After the search, we collated and uploaded all the identified records into EndNote v.X8 (Clarivate Analytics, Philadelphia, Pennsylvania) and removed any duplicates. Two independent reviewers (MCS and SA) screened the titles and abstracts for assessment in line with the inclusion criteria. They retrieved and assessed the full texts of the selected studies while applying the inclusion criteria. Any disagreements about the eligibility of studies were resolved by discussion or, if no consensus could be reached, by involving experienced researchers (MZ-S and RP).
The first reviewer (MCS) extracted data from the selected publications. For this purpose, an extraction tool developed by the authors was used. This tool comprised the following criteria: author(s), year of publication, country, research question, design, case definition, data sources, and methodologic and data-analysis triangulation. First, we extracted and summarized information about the case study design. Second, we narratively summarized the way in which the data and methodological triangulation were described. Finally, we summarized the information on within-case or cross-case analysis. This process was performed using Microsoft Excel. One reviewer (MCS) extracted data, whereas another reviewer (SA) cross-checked the data extraction, making suggestions for additions or edits. Any disagreements between the reviewers were resolved through discussion.
A total of 149 records were identified in 2 databases. We removed 20 duplicates and screened 129 reports by title and abstract. A total of 46 reports were assessed for eligibility. Through hand searches, we identified 117 additional records. Of these, we excluded 98 reports after title and abstract screening. A total of 17 reports were assessed for eligibility. From the 2 databases and the hand search, 63 reports were assessed for eligibility. Ultimately, we included 8 articles for data extraction. No further articles were included after the reference list screening of the included studies. A PRISMA flow diagram of the study selection and inclusion process is presented in Figure 1 . As shown in Tables 2 and and3, 3 , the articles included in this scoping review were published between 2010 and 2022 in Canada (n = 3), the United States (n = 2), Australia (n = 2), and Scotland (n = 1).

The following sections describe the research question, case definition, and case study design. Case studies are most appropriate when asking “how” or “why” questions. 1 According to Yin, 1 how and why questions are explanatory and lead to the use of case studies, histories, and experiments as the preferred research methods. In 1 study from Canada, eg, the following research question was presented: “How and why did stakeholders participate in the system change process that led to the introduction of the first nurse practitioner-led Clinic in Ontario?” (p7) 19 Once the research question has been formulated, the case should be defined and, subsequently, the case study design chosen. 1 In typical case studies with mixed methods, the 2 types of data are gathered concurrently in a convergent design and the results merged to examine a case and/or compare multiple cases. 10
“How” or “why” questions were found in 4 studies. 16 , 17 , 19 , 22 Two studies additionally asked “what” questions. Three studies described an exploratory approach, and 1 study presented an explanatory approach. Of these 4 studies, 3 studies chose a qualitative approach 17 , 19 , 22 and 1 opted for mixed methods with a convergent design. 16
In the remaining studies, either the research questions were not clearly stated or no “how” or “why” questions were formulated. For example, “what” questions were found in 1 study. 21 No information was provided on exploratory, descriptive, and explanatory approaches. Schadewaldt et al 21 chose mixed methods with a convergent design.
A total of 5 studies defined the case as an organizational unit. 17 , 18 - 20 , 22 Of the 8 articles, 4 reported multiple-case studies. 16 , 17 , 22 , 23 Another 2 publications involved single-case studies. 19 , 20 Moreover, 2 publications did not state the case study design explicitly.
This section describes within-method triangulation, which involves employing at least 2 data-collection procedures within the same design approach. 6 , 7 This can also be called data source triangulation. 8 Next, we present the single data-collection procedures in detail. In 5 studies, information on within-method triangulation was found. 15 , 17 - 19 , 22 Studies describing a quantitative approach and the triangulation of 2 or more quantitative data-collection procedures could not be included in this scoping review.
Five studies used qualitative data-collection procedures. Two studies combined face-to-face interviews and documents. 15 , 19 One study mixed in-depth interviews with observations, 18 and 1 study combined face-to-face interviews and documentation. 22 One study contained face-to-face interviews, observations, and documentation. 17 The combination of different qualitative data-collection procedures was used to present the case context in an authentic and complex way, to elicit the perspectives of the participants, and to obtain a holistic description and explanation of the cases under study.
All 5 studies used qualitative interviews as the primary data-collection procedure. 15 , 17 - 19 , 22 Face-to-face, in-depth, and semi-structured interviews were conducted. The topics covered in the interviews included processes in the introduction of new care services and experiences of barriers and facilitators to collaborative work in general practices. Two studies did not specify the type of interviews conducted and did not report sample questions. 15 , 18
In 2 studies, qualitative observations were carried out. 17 , 18 During the observations, the physical design of the clinical patients’ rooms and office spaces was examined. 17 Hungerford et al 18 did not explain what information was collected during the observations. In both studies, the type of observation was not specified. Observations were generally recorded as field notes.
In 3 studies, various qualitative public documents were studied. 15 , 19 , 22 These documents included role description, education curriculum, governance frameworks, websites, and newspapers with information about the implementation of the role and general practice. Only 1 study failed to specify the type of document and the collected data. 15
In 1 study, qualitative documentation was investigated. 17 This included a review of dashboards (eg, provider productivity reports or provider quality dashboards in the electronic health record) and quality performance reports (eg, practice-wide or co-management team-wide performance reports).
This section describes the between/across methods, which involve employing both qualitative and quantitative data-collection procedures in the same study. 6 , 7 This procedure can also be denoted “methodologic triangulation.” 8 Subsequently, we present the individual data-collection procedures. In 3 studies, information on between/across triangulation was found. 16 , 20 , 21
Three studies used qualitative and quantitative data-collection procedures. One study combined face-to-face interviews, documentation, and self-assessments. 16 One study employed semi-structured interviews, direct observation, documents, and service records, 20 and another study combined face-to-face interviews, non-participant observation, documents, and questionnaires. 23
All 3 studies used qualitative interviews as the primary data-collection procedure. 16 , 20 , 23 Face-to-face and semi-structured interviews were conducted. In the interviews, data were collected on the introduction of new care services and experiences of barriers to and facilitators of collaborative work in general practices.
In 2 studies, direct and non-participant qualitative observations were conducted. 20 , 23 During the observations, the interaction between health professionals or the organization and the clinical context was observed. Observations were generally recorded as field notes.
In 2 studies, various qualitative public documents were examined. 20 , 23 These documents included role description, newspapers, websites, and practice documents (eg, flyers). In the documents, information on the role implementation and role description of NPs was collected.
In 1 study, qualitative individual journals were studied. 16 These included reflective journals from NPs, who performed the role in primary health care.
Only 1 study involved quantitative service records. 20 These service records were obtained from the primary care practices and the respective health authorities. They were collected before and after the implementation of an NP role to identify changes in patients’ access to health care, the volume of patients served, and patients’ use of acute care services.
In 2 studies, quantitative questionnaires were used to gather information about the teams’ satisfaction with collaboration. 16 , 21 In 1 study, 3 validated scales were used. The scales measured experience, satisfaction, and belief in the benefits of collaboration. 21 Psychometric performance indicators of these scales were provided. However, the time points of data collection were not specified; similarly, whether the questionnaires were completed online or by hand was not mentioned. A competency self-assessment tool was used in another study. 16 The assessment comprised 70 items and included topics such as health promotion, protection, disease prevention and treatment, the NP-patient relationship, the teaching-coaching function, the professional role, managing and negotiating health care delivery systems, monitoring and ensuring the quality of health care practice, and cultural competence. Psychometric performance indicators were provided. The assessment was completed online with 2 measurement time points (pre self-assessment and post self-assessment).
This section describes data-analysis triangulation, which involves the combination of 2 or more methods of analyzing data. 6 Subsequently, we present within-case analysis and cross-case analysis.
Three studies combined qualitative and quantitative methods of analysis. 16 , 20 , 21 Two studies involved deductive and inductive qualitative analysis, and qualitative data were analyzed thematically. 20 , 21 One used deductive qualitative analysis. 16 The method of analysis was not specified in the studies. Quantitative data were analyzed using descriptive statistics in 3 studies. 16 , 20 , 23 The descriptive statistics comprised the calculation of the mean, median, and frequencies.
Two studies combined deductive and inductive qualitative analysis, 19 , 22 and 2 studies only used deductive qualitative analysis. 15 , 18 Qualitative data were analyzed thematically in 1 study, 22 and data were treated with content analysis in the other. 19 The method of analysis was not specified in the 2 studies.
In 7 studies, a within-case analysis was performed. 15 - 20 , 22 Six studies used qualitative data for the within-case analysis, and 1 study employed qualitative and quantitative data. Data were analyzed separately, consecutively, or in parallel. The themes generated from qualitative data were compared and then summarized. The individual cases were presented mostly as a narrative description. Quantitative data were integrated into the qualitative description with tables and graphs. Qualitative and quantitative data were also presented as a narrative description.
Of the multiple-case studies, 5 carried out cross-case analyses. 15 - 17 , 20 , 22 Three studies described the cross-case analysis using qualitative data. Two studies reported a combination of qualitative and quantitative data for the cross-case analysis. In each multiple-case study, the individual cases were contrasted to identify the differences and similarities between the cases. One study did not specify whether a within-case or a cross-case analysis was conducted. 23
This section describes confirmation or contradiction through qualitative and quantitative data. 1 , 4 Qualitative and quantitative data were reported separately, with little connection between them. As a result, the conclusions on neither the comparisons nor the contradictions could be clearly determined.
In 3 studies, the consistency of the results of different types of qualitative data was highlighted. 16 , 19 , 21 In particular, documentation and interviews or interviews and observations were contrasted:
Both types of data showed that NPs and general practitioners wanted to have more time in common to discuss patient cases and engage in personal exchanges. 21 In addition, the qualitative and quantitative data confirmed the individual progression of NPs from less competent to more competent. 16 One study pointed out that qualitative and quantitative data obtained similar results for the cases. 20 For example, integrating NPs improved patient access by increasing appointment availability.
Although questionnaire results indicated that NPs and general practitioners experienced high levels of collaboration and satisfaction with the collaborative relationship, the qualitative results drew a more ambivalent picture of NPs’ and general practitioners’ experiences with collaboration. 21
The studies included in this scoping review evidenced various research questions. The recommended formats (ie, how or why questions) were not applied consistently. Therefore, no case study design should be applied because the research question is the major guide for determining the research design. 2 Furthermore, case definitions and designs were applied variably. The lack of standardization is reflected in differences in the reporting of these case studies. Generally, case study research is viewed as allowing much more freedom and flexibility. 5 , 24 However, this flexibility and the lack of uniform specifications lead to confusion.
Methodologic triangulation, as described in the literature, can be somewhat confusing as it can refer to either data-collection methods or research designs. 6 , 8 For example, methodologic triangulation can allude to qualitative and quantitative methods, indicating a paradigmatic connection. Methodologic triangulation can also point to qualitative and quantitative data-collection methods, analysis, and interpretation without specific philosophical stances. 6 , 8 Regarding “data-collection methods with no philosophical stances,” we would recommend using the wording “data source triangulation” instead. Thus, the demarcation between the method and the data-collection procedures will be clearer.
Yin 1 advocated the use of multiple sources of evidence so that a case or cases can be investigated more comprehensively and accurately. Most studies included multiple data-collection procedures. Five studies employed a variety of qualitative data-collection procedures, and 3 studies used qualitative and quantitative data-collection procedures (mixed methods). In contrast, no study contained 2 or more quantitative data-collection procedures. In particular, quantitative data-collection procedures—such as validated, reliable questionnaires, scales, or assessments—were not used exhaustively. The prerequisites for using multiple data-collection procedures are availability, the knowledge and skill of the researcher, and sufficient financial funds. 1 To meet these prerequisites, research teams consisting of members with different levels of training and experience are necessary. Multidisciplinary research teams need to be aware of the strengths and weaknesses of different data sources and collection procedures. 1
When using multiple data sources and analysis methods, it is necessary to present the results in a coherent manner. Although the importance of multiple data sources and analysis has been emphasized, 1 , 5 the description of triangulation has tended to be brief. Thus, traceability of the research process is not always ensured. The sparse description of the data-analysis triangulation procedure may be due to the limited number of words in publications or the complexity involved in merging the different data sources.
Only a few concrete recommendations regarding the operationalization of the data-analysis triangulation with the qualitative data process were found. 25 A total of 3 approaches have been proposed 25 : (1) the intuitive approach, in which researchers intuitively connect information from different data sources; (2) the procedural approach, in which each comparative or contrasting step in triangulation is documented to ensure transparency and replicability; and (3) the intersubjective approach, which necessitates a group of researchers agreeing on the steps in the triangulation process. For each case study, one of these 3 approaches needs to be selected, carefully carried out, and documented. Thus, in-depth examination of the data can take place. Farmer et al 25 concluded that most researchers take the intuitive approach; therefore, triangulation is not clearly articulated. This trend is also evident in our scoping review.
Few studies in this scoping review used a combination of qualitative and quantitative analysis. However, creating a comprehensive stand-alone picture of a case from both qualitative and quantitative methods is challenging. Findings derived from different data types may not automatically coalesce into a coherent whole. 4 O’Cathain et al 26 described 3 techniques for combining the results of qualitative and quantitative methods: (1) developing a triangulation protocol; (2) following a thread by selecting a theme from 1 component and following it across the other components; and (3) developing a mixed-methods matrix.
The most detailed description of the conducting of triangulation is the triangulation protocol. The triangulation protocol takes place at the interpretation stage of the research process. 26 This protocol was developed for multiple qualitative data but can also be applied to a combination of qualitative and quantitative data. 25 , 26 It is possible to determine agreement, partial agreement, “silence,” or dissonance between the results of qualitative and quantitative data. The protocol is intended to bring together the various themes from the qualitative and quantitative results and identify overarching meta-themes. 25 , 26
The “following a thread” technique is used in the analysis stage of the research process. To begin, each data source is analyzed to identify the most important themes that need further investigation. Subsequently, the research team selects 1 theme from 1 data source and follows it up in the other data source, thereby creating a thread. The individual steps of this technique are not specified. 26 , 27
A mixed-methods matrix is used at the end of the analysis. 26 All the data collected on a defined case are examined together in 1 large matrix, paying attention to cases rather than variables or themes. In a mixed-methods matrix (eg, a table), the rows represent the cases for which both qualitative and quantitative data exist. The columns show the findings for each case. This technique allows the research team to look for congruency, surprises, and paradoxes among the findings as well as patterns across multiple cases. In our review, we identified only one of these 3 approaches in the study by Roots and MacDonald. 20 These authors mentioned that a causal network analysis was performed using a matrix. However, no further details were given, and reference was made to a later publication. We could not find this publication.
Because it focused on the implementation of NPs in primary health care, the setting of this scoping review was narrow. However, triangulation is essential for research in this area. This type of research was found to provide a good basis for understanding methodologic and data-analysis triangulation. Despite the lack of traceability in the description of the data and methodological triangulation, we believe that case studies are an appropriate design for exploring new nursing roles in existing health care systems. This is evidenced by the fact that case study research is widely used in many social science disciplines as well as in professional practice. 1 To strengthen this research method and increase the traceability in the research process, we recommend using the reporting guideline and reporting checklist by Rodgers et al. 9 This reporting checklist needs to be complemented with methodologic and data-analysis triangulation. A procedural approach needs to be followed in which each comparative step of the triangulation is documented. 25 A triangulation protocol or a mixed-methods matrix can be used for this purpose. 26 If there is a word limit in a publication, the triangulation protocol or mixed-methods matrix needs to be identified. A schematic representation of methodologic and data-analysis triangulation in case studies can be found in Figure 2 .

This study suffered from several limitations that must be acknowledged. Given the nature of scoping reviews, we did not analyze the evidence reported in the studies. However, 2 reviewers independently reviewed all the full-text reports with respect to the inclusion criteria. The focus on the primary care setting with NPs (master’s degree) was very narrow, and only a few studies qualified. Thus, possible important methodological aspects that would have contributed to answering the questions were omitted. Studies describing the triangulation of 2 or more quantitative data-collection procedures could not be included in this scoping review due to the inclusion and exclusion criteria.
Given the various processes described for methodologic and data-analysis triangulation, we can conclude that triangulation in case studies is poorly standardized. Consequently, the traceability of the research process is not always given. Triangulation is complicated by the confusion of terminology. To advance case study research in nursing, we encourage authors to reflect critically on methodologic and data-analysis triangulation and use existing tools, such as the triangulation protocol or mixed-methods matrix and the reporting guideline checklist by Rodgers et al, 9 to ensure more transparent reporting.

The case study research design have evolved over the past few years as a useful tool for investigating trends and specific situations in many scientific disciplines.
The case study has been especially used in social science, psychology, anthropology and ecology.
This method of study is especially useful for trying to test theoretical models by using them in real world situations. For example, if an anthropologist were to live amongst a remote tribe, whilst their observations might produce no quantitative data, they are still useful to science.
Basically, a case study is an in depth study of a particular situation rather than a sweeping statistical survey . It is a method used to narrow down a very broad field of research into one easily researchable topic.
Whilst it will not answer a question completely, it will give some indications and allow further elaboration and hypothesis creation on a subject.
The case study research design is also useful for testing whether scientific theories and models actually work in the real world. You may come out with a great computer model for describing how the ecosystem of a rock pool works but it is only by trying it out on a real life pool that you can see if it is a realistic simulation.
For psychologists, anthropologists and social scientists they have been regarded as a valid method of research for many years. Scientists are sometimes guilty of becoming bogged down in the general picture and it is sometimes important to understand specific cases and ensure a more holistic approach to research .
H.M.: An example of a study using the case study research design.
Some argue that because a case study is such a narrow field that its results cannot be extrapolated to fit an entire question and that they show only one narrow example. On the other hand, it is argued that a case study provides more realistic responses than a purely statistical survey.
The truth probably lies between the two and it is probably best to try and synergize the two approaches. It is valid to conduct case studies but they should be tied in with more general statistical processes.
For example, a statistical survey might show how much time people spend talking on mobile phones, but it is case studies of a narrow group that will determine why this is so.
The other main thing to remember during case studies is their flexibility. Whilst a pure scientist is trying to prove or disprove a hypothesis , a case study might introduce new and unexpected results during its course, and lead to research taking new directions.
The argument between case study and statistical method also appears to be one of scale. Whilst many 'physical' scientists avoid case studies, for psychology, anthropology and ecology they are an essential tool. It is important to ensure that you realize that a case study cannot be generalized to fit a whole population or ecosystem.
Finally, one peripheral point is that, when informing others of your results, case studies make more interesting topics than purely statistical surveys, something that has been realized by teachers and magazine editors for many years. The general public has little interest in pages of statistical calculations but some well placed case studies can have a strong impact.
The advantage of the case study research design is that you can focus on specific and interesting cases. This may be an attempt to test a theory with a typical case or it can be a specific topic that is of interest. Research should be thorough and note taking should be meticulous and systematic.
The first foundation of the case study is the subject and relevance. In a case study, you are deliberately trying to isolate a small study group, one individual case or one particular population.
For example, statistical analysis may have shown that birthrates in African countries are increasing. A case study on one or two specific countries becomes a powerful and focused tool for determining the social and economic pressures driving this.
In the design of a case study, it is important to plan and design how you are going to address the study and make sure that all collected data is relevant. Unlike a scientific report, there is no strict set of rules so the most important part is making sure that the study is focused and concise; otherwise you will end up having to wade through a lot of irrelevant information.
It is best if you make yourself a short list of 4 or 5 bullet points that you are going to try and address during the study. If you make sure that all research refers back to these then you will not be far wrong.
With a case study, even more than a questionnaire or survey , it is important to be passive in your research. You are much more of an observer than an experimenter and you must remember that, even in a multi-subject case, each case must be treated individually and then cross case conclusions can be drawn .
Analyzing results for a case study tends to be more opinion based than statistical methods. The usual idea is to try and collate your data into a manageable form and construct a narrative around it.
Use examples in your narrative whilst keeping things concise and interesting. It is useful to show some numerical data but remember that you are only trying to judge trends and not analyze every last piece of data. Constantly refer back to your bullet points so that you do not lose focus.
It is always a good idea to assume that a person reading your research may not possess a lot of knowledge of the subject so try to write accordingly.
In addition, unlike a scientific study which deals with facts, a case study is based on opinion and is very much designed to provoke reasoned debate. There really is no right or wrong answer in a case study.

In this study, the researchers explore lecturers’ perspectives on the impact artificial intelligence (AI) has on blended learning within the context of South African higher education. AI is transforming traditional teaching and learning by enabling academic institutions to offer computerised, effective, and objective educational processes. The research was conducted to address the growing need to understand lecturers’ viewpoints on how AI can enhance educational practices and overcome existing challenges in blended learning environments. To investigate this phenomenon, the researchers applied the Substitution, Augmentation, Modification, and Redefinition (SAMR) model as theoretical framework for the study. Their qualitative research undertaking employed a singular case study design focusing on 15 lecturers from the College of Education at a selected academic institution, to arrive at an in-depth understanding of lecturers’ experiences and perceptions of how AI is integrated in blended learning. The researchers examined both the benefits and challenges associated with a blended teaching and learning mode, in the context of AI integration. The data collection process involved semi-structured focus group interviews that allowed for in-depth discussions to be conducted. This was complemented by detailed document analysis to analyse the course materials and teaching methods used by the lecturers. Homogeneous, purposeful sampling was applied to select participating lecturers who shared specific characteristics relevant to the study. Data analysis involved coding through the induction method, which helped to reveal relevant codes that were subsequently categorised. The study also included a comprehensive literature review of recent research findings, which were correlated with the collected data. The findings underscored the critical need for supportive measures, such as management backing, enhanced training opportunities, professional development initiatives, reliable technological infrastructure, improved internet connectivity, and additional time allocation, for the successful implementation of blended learning which integrates AI. This study contributes valuable insights into, and discussions on, the implications of adopting AI in a hybrid learning environment.

Over the past few years there have been notable advances in supporting lecturers to enhance their teaching methods, and in improving students’ learning experiences through the adoption of blended learning. Defined as a combination of face-to-face (F2F) and online learning, blended learning offers more flexible learning experiences that are also deemed to be more effective. Also known as "brick-and-click" instruction, hybrid learning, dual-mode instruction, blended pedagogies, or HyFlex, targeted, multimodal or flipped learning [ 5 , 38 ], this approach is becoming increasingly popular. The approach, which combines traditional classroom F2F learning with online components, facilitates the application of asynchronous teaching and learning in educational settings [ 16 ]. In recent years, educational institutions have widely embraced blended learning as the preferred teaching method, expressing appreciation for its flexibility, timeliness, and uninterrupted learning opportunities. As hybrid learning gains popularity, so it has become increasingly important to find new ways of improving the effectiveness thereof [ 17 ]. Recent developments in artificial intelligence (AI) are one way of enhancing the efficacy of blended learning approaches. With the integration of AI into academic environments, individualised learning experiences can be provided, administrative tasks can be automated, and such systems can be adapted to student needs [ 20 , 44 ]. For these reasons, the researchers sought to understand lecturers’ views on the relationship between AI and blended learning, as those perspectives are crucial for developing effective teaching and learning practices in higher education contexts.
AI involves the study and development of computer programs that display ‘intelligent’ behaviour, mindful of the fact that machine intelligence is distinct from the natural intelligence that is inherent in humans and animals. Other definitions of AI examine efforts to enable computers to possess intelligence [ 19 ]. Ultimately, AI extends much further than just robotics, however, to include the human capacity to program computers and other technology-enabled devices, so that they comprehend the principles of intelligent thought and behaviour. As a key invention of the Fourth Industrial Revolution (4IR), AI is considered one of the most influential technologies of our time [ 19 ]. For the purposes of this research, AI will be taken to refer to the development of computer systems capable of performing tasks that typically require human intelligence, such as learning, problem solving, and decision making. From the point of view of lecturers, such integration would require them to adapt their teaching and learning approaches, to make them more efficient and effective in addressing diverse student needs [ 25 ].
It is against this background that the researchers felt the need to investigate what impact AI has on blended learning, which includes lecturers having to revisit the way in which they usually lecture (the educator teaching, and students listening and regurgitating what they have been taught), to scenarios where AI is infused into a hybrid learning approach. It is crucial to emphasise that, in the context of this paper, blended learning is deemed to comprise more than the mere incorporation of technology into an academic programme. The adoption of the term, in this instance, aligns with what Lee [ 24 ] describes as a hybrid teaching approach, integrating traditional F2F lecturing with the latest, updated technologies. This mode aims to enhance student success and promote the relevance of the course content. Interaction among students, and between lecturers and the student cohort, is accomplished through various internet-enabled learning technologies, including platforms such as online discussion forums [ 3 ]. These technologies play a crucial role in promoting communication between educational stakeholders. Consequently, the smooth integration of conventional classroom instruction with e-learning offers valuable support for students’ asynchronous and collaborative learning [ 15 ]. In addition, the use of AI supplements these interactions by providing personalised feedback, allowing for two-way discussions, and for learning resources to be adapted to individual students’ needs. This combination of traditional and e-learning environments through the adoption of AI technologies makes for a more engaging and effective educational experience. It improves educational access, and promotes inclusive and equitable education, resulting in a sustainable, efficient, and accessible system of blended learning [ 3 ].
Although blended learning is not a novel concept, its use has remained largely unchanged. Its numerous challenges require further and more in-depth research into its efficacy [ 5 , 38 ]. Various aspects, including the specific technological tools and learning approaches used, and the overall quality of the teaching and learning on offer, need examination [ 5 ]. While blended learning has long been used as an approach to enhance students’ learning experiences, much of the research has focused on countries in the Global North, such as Belgium, the United Kingdom (UK), and Italy [ 6 ]. Limited research has been conducted in the South African context in this regard [ 43 ]. Notably, a search on Google Scholar revealed that only minimal related research has been published in the past 5 years (only eight research resources), with none of them originating from South Africa. Despite the increased uptake of hybrid learning in academia, AI is often perceived as a separate technological tool with limited influence on teaching and learning approaches. To enhance the effectiveness of blended learning in higher education contexts, it is essential to identify and understand lecturers’ views on the incorporation of AI into their teaching and learning, taking into account the SAMR model [ 34 ].
The significance of the study thus lies in elucidating lecturers’ viewpoints on the impact which AI and blended learning have on teaching and learning. The researchers also set out to assist higher education institutions (HEIs) in creating, adapting or changing conditions so that they are more relevant and meaningful, and ultimately enable lecturers to ensure that students are more successful in achieving specific learning outcomes. Clearly, AI is a tool that must be embraced in this modern, ever-evolving technological world.
The main research question designed to guide the study, was:
How do lecturers perceive the influence of AI on blended learning in the context of a South African higher education institution?
Four sub-questions were also formulated in this regard:
How do lecturers in South African higher education institutions perceive and integrate AI technologies into blended learning lessons within the SAMR framework?
What challenges do lecturers identify when incorporating AI into blended learning lessons, considering the SAMR levels of substitution, augmentation, modification, and redefinition?
How does AI influence student engagement, interaction, and learning outcomes in blended learning environments?
What support mechanisms do lecturers require to ensure the successful incorporation of AI into blended learning lessons?
Following the above introductory discussion on lecturers’ perspectives on blended learning and AI integration, the sections which follow focus on a comprehensive literature review on the topic, the theoretical framework chosen for this research, an exploration of the selected research methodology, the findings, and recommendations for the successful implementation of blended learning infused with AI. Lastly, concluding remarks summarise the key findings, and outline implications for future research and educational practice.
After exploring the background and rationale for this study, it is crucial that this study examines the existing body of research related to blended learning and Artificial Intelligence integration in higher education which is the focus of the next section.
2.1 blended learning as an approach to teaching and learning.
In recent years, the educational domain has experienced significant transformations, driven by the continued evolution of information technology. One notable outcome is the emergence of blended learning, a pedagogical approach that integrates diverse methods of delivering information, such as web-based software courses, coupled with the management of practical knowledge [ 33 ]. According to Damanik [ 12 ], Choi and Park [ 10 ], and Qiu et al. [ 35 ], blended learning can be implemented both on- and offline. Bozkurt [ 8 ] expands on this, emphasising that blended learning encompasses F2F interactions and online engagement through specific mediums. The positive impact of the blended learning model on students’ learning outcomes, through fostering heightened engagement, is echoed by Santosa et al. [ 39 ]. This model, as observed by Nugraha et al. [ 31 ], also enhances students’ problem-solving abilities and understanding of the module content. This ensures adaptability and flexibility that caters to individual students’ needs, preferences, and schedules [ 43 ]. While initially designed for specific modules and their content, this approach prioritises student-centred satisfaction [ 43 ], thereby supporting HEIs in pursuing their goals and ultimately achieving the successful attainment of the learning outcomes set [ 38 ]. At its core, the concept of blended learning is built on the understanding that learning is not a singular, isolated event, but rather an ongoing, continuous process [ 33 ]. This transformational shift aligns with the modification level of the SAMR model, as it goes beyond merely substituting traditional teaching methods with technology, instead modifying the entire learning experience. Admittedly, the development of efficient blended learning systems can be demanding, particularly in respect of their endurance and flexibility to adapt to modern technological developments [ 3 ].
The integration of Artificial Intelligence (AI) in blended learning environments has been the subject of increasing debate in recent years. A review of the literature reveals that while there are some global studies completed which have explored various aspects of AI in education, research originating from South Africa is notably sparse. Alshahrani [ 3 ], Ferry et al. [ 13 ], and Rahman et al. [ 37 ] have all examined the impact of AI on student engagement and learning outcomes in blended learning, highlighting the potential benefits of AI-driven feedback and personalised learning experiences. However, research from a South African context is underrepresented, which may limit the generalisability of these findings to local settings. This gap highlights the need for more region-specific studies, particularly in HEIs.
The year 2017 marked a significant milestone, with extraordinary and unique developments in our understanding of the possibilities of the merging of technology and AI. As a rapidly advancing field, AI has the potential to influence the future of information technology and, for this reason, training in that regard is imperative [ 33 ]. The study of AI is fascinating and intriguing, representing the future of information technology. AI has the potential to enhance people’s lives by ensuring that tasks are accomplished more rapidly and more accurately. Petrova [ 33 ] suggests that soon AI will be integrated into all platforms and technologies, across different spheres. This development represents a shift toward the redefinition level of Puentedura’s [ 34 ] SAMR model. It transcends the traditional roles of both lecturers and students and introduces new possibilities for teaching and learning through the use of technology. While there is still substantial work ahead, AI empowers lecturers to achieve more—and with greater efficiency—than ever before. In the past, AI was a technology that instilled fear in many. The notion that computers could think and learn like humans raised concerns about our ability to comprehend and constrain machines. However, as we move away from the pursuit of human-like AI, we can now view its progress as a tool serving to develop and enhance every industry [ 33 ].
AI stands out as a potential answer to improve the efficiency and durability of blended learning systems [ 3 , 23 ]. Through the use of AI techniques such as machine learning (ML), natural language processing (NLP), and chatbots, opportunities are created which allow for the automation of diverse features of the learning journey, including content delivery, assessment, and feedback [ 3 , 22 ]. Furthermore, AI allows for the customisation of the learning experience for individual students, ensuring increased engagement and enhancing learning outcomes [ 3 ]. The fact that AI makes it possible for lecturers to adapt and automate their teaching, represents a change in traditional teaching and learning methods, aligning with the substitution as well as modification levels of the SAMR model, as technology can be used as a direct substitute for conventional teaching and learning methods, while also accommodating or revealing new capabilities. It offers a vast range of new possibilities to help ensure the successful achievement of a module’s learning outcomes—something that was not possible with conventional approaches.
It became clear to the researchers that while relevant, limited studies on this theme exist in South Africa, Mhlanga [ 27 ] and Mokoena [ 28 ] explored the challenges and opportunities of implementing AI in South African HEIs. These studies highlight the need for more specific approaches that consider the unique socio-economic and technological constraints, such as limited access to high-speed internet and the variability in digital literacy among both students and staff. These insights are crucial for understanding how AI can be effectively integrated into blended learning environments in South Africa, ensuring that such integration is successful, equitable and sustainable.
Moreover, there is a critical need for research that addresses the localised implementation of AI-driven blended learning solutions, particularly in rural and under-resourced areas where access to technology is inconsistent [ 27 ]. Such studies would provide valuable insights into how AI can be utilised not only to enhance learning outcomes but also to bridge the educational disparities that persist across different regions of the country. While limited, some relevant studies do exist. Mhlanga [ 27 ] and Mokoena [ 28 ] explored the challenges and opportunities of implementing AI in South African HEIs. These studies highlight the need for more specific approaches that consider the unique socio-economic and technological constraints, such as limited access to high-speed internet and the variability in digital literacy among both students and staff. These insights are crucial for understanding how AI can be effectively integrated into blended learning environments in South Africa, ensuring that such integration is successful, equitable and sustainable.
Integrating AI into blended learning systems offers the potential to establish an education system that is not only efficient, but also sustainable. The use of AI in education, particularly in blended learning, revolves around delivering personalised learning experiences, and optimising course delivery [ 3 , 2 , 24 ]. Through the adoption of AI technology in hybrid learning systems, it is easier for lecturers to analyse student performance data for a personalised learning experience which aligns with individual strengths, weaknesses, and interests [ 3 , 25 ]. The implementation of AI in blended learning streamlines tailored assistance for students. Alshahrani [ 3 ] concurs that AI allows for responsive interaction. This corresponds to the augmentation (A) level of the SAMR [ 34 ] model, where technology is used to improve the learning experience, exceeding what was achievable with traditional methods. Personalised support can easily be based on individual student needs. The personalised approach assists students in navigating complex concepts, thus helping to ensure the achievement of learning outcomes, and ultimate success.
AI is also conducive to enhancing teaching and learning methods, increasing efficiency through automated administrative tasks, and refining content delivery. Introducing AI tools to ensure a sustainable and efficient blended learning system allows lecturers to lessen the strain on the environment, by reducing paper usage and minimising the carbon dioxide emissions associated with physical (F2F) lectures or meetings. This not only improves educational effectiveness and accessibility, but also empowers students to acquire the essential knowledge and skills for building a sustainable future [ 3 , 36 ].
Viktorivna et al. [ 40 ] point out that AI serves to enhance student engagement, and the effectiveness of their learning. AI also facilitates a more straightforward explanation of subject matter [ 32 ], thereby encouraging students to develop and enhance skills required in the twenty-first century [ 11 , 42 ]. AI is a valuable educational resource for blended learning, as it grants access to an ever-expanding range of learning materials. Furthermore, AI helps in the creation of lessons, quizzes, and rubrics which allow lecturers to reorganise the curriculum and content of a module. AI-generated resources can even be customised to align with students’ instructional preferences, thereby fostering a flexible and inclusive learning experience [ 3 ].
Various studies have shown that the infusion of AI in a blended learning module enriches the learning process for students, helping them attain specific learning outcomes [ 13 , 14 , 37 , 39 ]. The collaborative and conversational capabilities of AI enhance the overall learning experience, resulting in an enjoyment of the course and heightening active participation among the student cohort. Concerted engagement delivers improved learning outcomes, and a more profound understanding of the subject matter [ 3 ]. This aligns with the Augmentation (A) level of the SAMR model, as technology (AI in this instance) goes beyond merely enhancing traditional methods, to develop a more interactive and engaging learning environment, thus fostering increased student participation and leading to a better grasp of the subject matter.
The AI-based blended learning model boosts students’ digital literacy levels as well as their 21st-century thinking skills [ 37 ]. This innovative approach helps to improve their critical thinking skills, for use in the learning process [ 18 ]. Ultimately, models can be created using a variety of AI-based technologies, thereby saving lecturers time and enhancing students’ learning opportunities [ 37 ].
In higher education, large class sizes make it difficult for lecturers to offer individualised teaching and can impede swift and direct student support. AI negates this challenge by rendering personalised support. As such, AI delivers real-time answers and support, easing the workload on lecturers and enriching the learning experience. The rise in popularity of AI has initiated extensive discourse and research regarding its potential influence in the education sector, particularly in higher education where limited lecturer–student ratios present unique challenges [ 3 ]. Thus, it is clear that AI serves as a valuable asset in blended learning.
AI also enables the delivery of customised support, feedback, and motivation to students. Investigating these aspects will further our understanding of AI’s integration in blended learning, unveiling fresh insights to guide the design, implementation, and ethical use of related technologies in educational environments that adopt a hybrid learning approach [ 3 ]. Since this is a relatively new technological development and thus a relatively novel approach to teaching and learning, further research is needed, especially at HEIs, to analyse the exact impact on students’ performance. As Rahman et al. [ 37 ] concur, this approach needs further development. This research paper extends the current knowledge base in the field of blended learning, particularly in higher education, by providing insights into the integration of AI for enhanced student literacy, thereby filling a significant gap in the existing literature. Closing this gap will not only expand our understanding of emerging educational practices, but also provide valuable insights for educators, institutions, and policymakers aiming to optimise the student learning experience.
The follow section reviews the theoretical framework that guided this research.
For this research, the Substitution, Augmentation, Modification, and Redefinition (SAMR) theoretical model was selected, to establish a solid foundation for investigating intricate aspects of AI’s influence on blended learning in HEIs. The model was chosen for its applicability to an understanding of the transformative impact of AI on blended learning, within the South African higher education milieu.
As per Puentedura’s [ 34 ] SAMR model, digital technologies can either enhance or transform educational practice. Enhancement involves substitution without functional change, or augmentation with functional improvement. Transformation, by contrast, requires significant task redesign or redefinition, leading to the creation of new tasks that were previously inconceivable. The model, which explores the creative application of technology to enhance the learning experience, serves as a useful guide for lecturers facing pedagogical changes as a result of using new learning technologies in their courses [ 30 ].
The SAMR model comprises four hierarchical levels. Firstly, the substitution level in which technology is used as a direct substitute for a traditional tool, with no functional change. At this level, the lecturer is tasked with substituting an older technology to perform the same activities as previously. While this may set the stage for future development, it is unlikely to have a significant impact on student outcomes at this stage [ 30 ]. The second level, augmentation, prompts lecturers to consider whether or not the available technology improves their teaching and learning. Instead of merely observing how students performed a given task before, lecturers must now focus on specific features of the technology, to accomplish the task more effectively, informatively, and swiftly. This approach aims to enhance students’ performance in completing assigned tasks [ 30 ]. Thus, technology acts as a direct substitute, with some functional improvement. The third level is the modification level in which technology allows for significant task redesign and, during modification, the lecturers’ objectives are to successfully achieve lesson outcomes with technological assistance. Teaching methods are thus adapted to ensure the incorporation of technology. While the syllabus remains unchanged, teaching approaches are modified to enable students to attain new goals that were previously deemed challenging [ 30 ]. The final level of redefinition empowers lecturers to replace older teaching techniques with newer, more effective teaching ideas. This is achieved through the use of technology, which allows for the creation of tasks once deemed inconceivable [ 7 ]. These teaching methods mainly seek to capture and retain students’ attention [ 30 ].
The SAMR framework enhances the value of the accumulated data, by offering a decision-making model for assessing the design of research interventions. The lowest levels—substitution and augmentation—encourage participants to actively engage, thus overcoming challenges related to technology, pedagogy, and their consequences. At the higher levels—modification and redefinition—the design of research questions becomes crucial for considering potential challenges in participants’ understanding of increasingly complex topics. This approach aims to purposefully overcome obstacles associated with the evolving nature of the scheduled tasks [ 4 ].
The application of the SAMR model in the context of this research involved a comprehensive examination of how AI influences blended learning practices. At the Substitution level, the study explored how AI replaces or replicates traditional teaching methods, offering insights into its role in directly substituting conventional approaches. Moving to the Augmentation level, the research assessed how AI enhances or improves existing educational practices, particularly in terms of providing additional features or functionalities that support teaching and learning. The Modification level focused on analysing how AI introduces significant changes in the execution of educational tasks, transforming traditional methods into more dynamic and effective practices. Finally, at the Redefinition level, the study evaluated how AI facilitates entirely new and transformative educational practices that were previously unattainable, showcasing its potential to revolutionise blended learning environments in ways that were not possible before.
Using this framework ensured that the research could follow a systematic approach to assessing the influence AI exerts on blended learning. It allowed the research to progress from simple enhancements to transformative changes. By offering a structured method for assessing the extent of AI integration in various facets of teaching and learning, the researchers gained valuable insights into the evolving landscape of educational technologies.
It is against this background that the chosen methodology is discussed next.
4.1 research approach.
This study applied a qualitative methodology to investigate lecturers’ views on the influence AI has on blended learning. A qualitative approach involves a thorough exploration and grasp of phenomena, using non-numerical data and highlighting context, meanings, and subjective experiences [ 21 ]. The researchers deemed this method best suited for its exploratory nature of extracting relevant information. Focus group interviews were conducted, as Islam and Aldaihani [ 21 ] suggest, to allow for the coordination of discussions among a small group of participants, to mine and gather their views on a specific topic or phenomenon. For this research the focus was on the modules, lessons, and assessments of the participating lecturers. In addition, the researchers employed document analysis, which enabled them to explore the actual course content, lesson plans, and discussion forums.
In this way, the researchers arrived at an in-depth understanding of the specific phenomenon under investigation, as proposed by Morgan [ 29 ]. This approach enabled the researchers to scrutinise the lecturers’ experiences and opinions, focusing on their knowledge of, and encounters with, AI and blended learning.
The researchers applied a singular case study research design. This involved focusing on a single participant or unit of analysis, for an in-depth exploration of the intricacies and dynamics of a specific case [ 1 ]. This approach made it possible to conduct a thorough examination of the perceptions of lecturers employed in the College of Education at the HEI in question. The choice of design was prompted by ongoing developments in both AI and blended learning, which enabled the researchers to gain insights from lecturers actively engaged in related emerging educational practices.
Identifying a population for a particular research study enables the researchers to gather pertinent information from a smaller representative sample. This ensures that each distinct element of the collected information with similar characteristics is given the opportunity to be part of the sample. The researchers opted to employ a homogeneous purposeful sampling technique, intentionally selecting a group of participants who shared specific characteristics or traits deemed relevant to the research objectives. Participants were thus chosen based on shared traits, including gender, age, years of experience, the college in which they lectured, and their use of AI and blended learning, in order to align with the study’s purpose and objectives (Table 1 ).
Here, the group of participants selected were part of the same college at the specific HEI. The criteria for selection encompassed their approachability, availability to actively participate in the study, responsiveness to the interview questions, and willingness to share the content of their modules, lessons, and assessments. For this study, 15 lecturers agreed to participate: two males and 13 females, ranging in age between 32 and 63. Importantly, age has an impact on a user’s acceptance and embrace of AI in teaching and learning. Older lecturers often express discomfort with new technology adoption, and tend to be resistant to change. They are usually more comfortable with traditional ways of teaching and are fearful of using cutting-edge technological innovations. The participants’ readiness to openly share their course content, lessons and assessments, assisted the researchers in effectively analysing the collected data through the chosen document analysis data-collection technique. Consequently, the participants contributed valuable information that enhanced the depth of the study. Their active involvement in university affairs (especially the teaching and learning programmes) provided information that was highly relevant to this research .
For this study, data were acquired by conducting interviews with the participating lecturers, enhanced by document analysis (see appendices A and B). The application of these data-collection techniques enabled the researchers to gather pertinent insights into the lecturers’ practical encounters with AI and blended learning in their teaching and learning. The use of open-ended, semi-structured interviews, along with document analysis, facilitated the analysis of the data, thus ensuring a thorough and precise in-depth study of the subject matter. The thematic approach adopted in this research aimed to pinpoint repeated topics identified in the data gathered. This enabled the researchers to concentrate on emerging themes specific to the realm of AI and blended learning, rather than providing mere synopses of the data [ 9 ].
To gain valuable insights from the participants’ answers to the interview questions, and information derived from the document analysis, a thorough study and interpretation of the collected data was imperative—an analytical process which is crucial for answering the research questions effectively. The researchers actively engaged in interpreting, consolidating, and synthesising the lecturer participants’ statements, to assign meaning to the data. This involved transcribing, comparing, and scrutinising the interview responses, along with the content of the modules, lessons, and assessments. The participant responses were coded manually, using letters of the alphabet, to ensure anonymity. Each response was tagged with a corresponding letter, making it possible to trace every piece of data back to the specific participant who supplied it. Each statement was carefully linked to specific codes and themes, especially given the fact that AI does not replace F2F lecturing, but rather augments teaching and learning. The coding process involved categorising data into the SAMR [ 34 ] levels, to reach conclusions about how lecturers perceive AI's influence on different aspects of blended learning.
The thematic approach was used to identify patterns and themes in the data, which were then related back to Puentedura’s [ 34 ] SAMR model. This allowed for a comprehensive review of how AI is being used at different levels of integration in a specific hybrid learning environment. An inductive approach, specifically axial coding, was followed to analyse the data collected. This involved a systematic comparison of the gathered data to identify codes, categories, and subcategories. A natural analysis of the data, without preconceived notions, was achieved by using an inductive approach, which enabled an unbiased analysis of the lecturers’ actual experiences. Through this comparative analysis, the researchers aligned the collected data with information derived from the literature review. The adoption of these methodologies facilitated the analysis of findings, reinforcing the credibility and reliability of the data. The theoretical justifications for this approach included grounding the findings within the SAMR framework, to enable the data-analysis process to align with the study objectives and research questions throughout.
Ensuring the credibility and trustworthiness of research findings is the prerogative of every qualitative researcher. In this study, the researchers developed a lasting, reliable, and open relationship with the participants. This approach guaranteed the latter’s willingness to actively participate in the study, and to share their personal experiences of the impact which AI has on blended learning. Moreover, the lecturers were encouraged to review and offer feedback on the researchers’ summary of the interview responses, further confirming the accurate representation of all data, and strengthening the trustworthiness of the research.
The coding process for this study was primarily conducted by Researcher A who began the initial coding of the qualitative data, identifying preliminary themes and patterns. To enhance the reliability of the analysis, researcher B participated in the second phase, where both researchers reviewed and validated the initial codes and themes. This collaborative approach involved both open coding and axial coding and ensured a thorough and unbiased interpretation of the data. A critical reader provided feedback and suggestions, which helped refine the coding framework and resolve any discrepancies. This process promoted credibility by introducing different perspectives, which prevented individual prejudice and improved the accuracy of the data interpretation. Transparency was achieved by clearly documenting each researcher’s role and contributions, making the process open to scrutiny and validation by other future researchers. The method ensured the reliability and comprehensiveness of the data analysis and actual results.
The researchers adhered strictly to qualitative research principles, ensuring transparency in their data-collection methods and meticulousness in their data-analysis techniques. Participants were continually asked to check the researchers’ notes, interpretation of the interviews, and transcriptions (member checking). Detailed descriptions of the participants’ experiences were provided to enable the transferability of the findings. This precise approach guaranteed the reliability and validity of the findings. By integrating the findings from the interviews, document analysis, and literature review, the validity and trustworthiness of the conclusions were further enhanced. Through this methodological approach, the researchers ensured the trustworthiness of the research findings and were able to make informed recommendations based on the results reported on here.
The chair of the department in which the research was undertaken, obtained comprehensive ethical clearance covering the entire department from the Research Ethics Review Committee of the College of Education of the particular HEI. This clearance authorises all researchers in the department to conduct research within the institution, under ethics clearance number 90060059MC.
In ensuring that the highest ethical standards were maintained, the researchers pledged to use codes to protect the identity and privacy of the participating lecturers. The lecturers were also required to give the researchers permission to record the interviews, and to analyse their module content, lessons, and assignments. They were explicitly informed that their participation was voluntary, and that they were free to withdraw from the study at any stage without fear of penalty.
Here, the researchers summarise the outcomes of the research based on insights derived from the responses provided during the interviews with the participating lecturers, and the document analysis. The findings are organised to address the main research question and sub-questions.
Of the 15 participants interviewed, 12 reported using AI to ensure that student queries were answered, and that they could find additional information as required, thus personalising the entire academic journey. In the words of Lecturer H:
I use AI in my modules to ensure that students can easily obtain answers to their questions. It is an amazing tool which helps suggest supplementary resources based on students' progress. This ensures a learning experience which is better, as it is adapted to my students’ progress.
Lecturer C corroborated this:
These systems can answer questions, provide information, and simulate conversation, creating an amazing and enjoyable interactive environment.
The same 12 lecturers deemed AI very useful for facilitating discussions between lecturers and students, and students amongst themselves. This was achieved because AI streamlined communication, enhanced interaction, and provided valuable support. Lecturer F said:
AI has significantly improved communication channels; it allows me to develop interactive and engaging discussions between students and between students and myself, and even encourages students to discuss the course content amongst themselves.
Lecturer H concurred:
The use of AI chatbots has created a space for students to collaborate effectively. This offers immediate assistance and helps develop a sense of collaboration in our blended learning environment.
All the interviewees maintained that the use of AI to generate relevant and customised learning materials and assessments was a very useful feature that could easily be adopted in blended learning modules. In this regard, Lecturer C said:
I use AI to create customised learning materials, quizzes and even games that align with the specific learning outcomes of my modules.
Lecturer G stated:
I find that the fact that AI can create adaptive assessments that adjust difficulty levels based on the individual performance of my students, is very useful.
Five participants highlighted the value of AI for translation. This was considered extremely useful, particularly in the South African context with 11 official languages. Lecturer M explained:
The ability of AI to facilitate translation greatly benefits our students from diverse backgrounds. It is so easy for any of us [lecturers and students] to quickly translate a word or even a whole paragraph, which makes the understanding of the module so much easier.
Lecturer H added:
I find that it helps students who are more comfortable in their home language to participate in the course content. This ensures that learning materials are accessible to everyone, regardless of their language preference.
The researchers’ document analysis showed that lecturers who mentioned the benefits of AI for creating customised learning materials and adaptive assessments had indeed merged these elements into their module sites. This correlated with the findings obtained from the interviews, where 12 of the 15 participating lecturers highlighted the positive impact AI had on facilitating communication, enhancing interaction, and offering support in hybrid learning environments. In addition, the analysis revealed instances where AI tools were used to support F2F classes by providing real-time feedback and interactive activities, thus enriching the blended learning experience. Using technology to individualise learning experiences and adapt teaching strategies in real-time helps students adapt to such approaches, thereby supporting traditional teaching methods and enriches learning environments.
Lecturer C had integrated AI-generated, scenario-based case studies into the course material. The document analysis revealed a scenario related to cultural integration through language teaching and learning. Students were presented with a case study involving a classroom with learners from diverse linguistic and cultural backgrounds. They were tasked with designing a language lesson that not only focused on language acquisition, but also promoted cultural understanding and integration. AI was used to evaluate the students’ answers to the case study. Based on individual performance, the system provided feedback to each individual student, and suggested additional resources or challenges to focus on specific areas of improvement in designing the language lesson.
The document analysis (as outlined in the second criterion, which aimed to “examine evidence of how assessments reflect the unique contributions of AI to student learning outcomes”) also ascertained the presence of adaptive assessments that were able to adjust complexity levels based on individual student performance. Lecturer G, who felt that AI was beneficial for creating such assessments, had incorporated quizzes with dynamic difficulty levels into the module site. Students were able to complete personalised assessments, with questions based on their previous performance.
The researchers noted the integration of AI-based translation services. Lecturer M, who highlighted the value of AI for translation, had implemented an AI-driven language translation tool on the module site. The researchers noted that some students had translated sections of the course content into their preferred language, promoting inclusivity and ensuring that the specific learning materials were clear to everyone, regardless of their language preference.
Four of the lecturers interviewed, described the adaptation of new methods of teaching and learning, when using AI in their blended learning modules, as a challenge. In response to interview question 5 (What challenges have you encountered when incorporating AI into blended learning, and how did you overcome them?), Lecturer H commented:
Incorporating AI into my modules requires a delicate balance. I found that at times AI tends to minimise the importance of traditional teaching and learning methods, and not actually enhance them.
Lecturer B said:
Finding the right blend is crucial, so students benefit from the best of both worlds. AI must enrich my module and definitely not disrupt it … [We have to find] a balance between the technology and the personalised touch.
Lecturer C indicated:
… it can be a challenge to decide exactly where AI should be incorporated into the actual content of the course. Determining this often requires me to rethink my learning outcomes and approaches to teaching the content of my modules.
Twelve participants expressed the view that resistance to change was a major impediment to the successful adaptation of AI in blended learning modules. This aligns with responses to Interview Question 9 (In your experience, what support or resources do lecturers currently require when implementing AI in blended learning?) where Lecturer G noted:
Change is always met with resistance, especially when it comes to technology, particularly amongst us older lecturers. Some may see AI as a threat to the traditional way of teaching.
Lecturer H stated:
There's a comfort in the familiar, and AI represents a significant shift. Overcoming resistance requires effective communication. It also requires practically exploring the uses and benefits of AI.
All the participants mentioned that, although AI definitely saved time, problems were experienced with finding additional time to investigate new technologies and adapt their modules accordingly. In the words of Lecturer A:
While AI streamlines certain processes, the challenge lies in actually finding dedicated time for exploring its full potential to ensure that AI helps both me and my students successfully achieve the outcomes of the specific module.
Lecturer G mentioned:
Despite the efficiency AI brings, we must confront the reality of time constraints. It is essential to find a balance between adopting new technologies and meeting existing teaching demands.
Eight participants mentioned that it was becoming increasingly challenging to cope with the problem of the “digital divide”, which pertains to the technological proficiency of the students. Lecturer E noted:
There's a noticeable difference in access to technology among our students, and it's becoming increasingly challenging for us lecturers to bridge this gap as a result of the fast pace of new technological developments.
Lecturer F concurred, adding:
The issue of unequal access is growing. We need effective strategies to ensure all students are given equal learning experiences, regardless of their experience using computers for actual learning.
Several lecturers discussed ethical and privacy-related challenges with regard to the integration of AI in their blended learning module. As Lecturer F indicated:
I find that a huge challenge is that of ethical considerations, especially with regard to the privacy of student data. Finding the correct balance between using AI and protecting our students' privacy is an ongoing challenge. Additionally, there's a need for clear guidelines from management on how AI should be used ethically in our teaching, to avoid unintended consequences.
Lecturer G opined:
The challenge lies in providing the benefits of using AI to achieve the outcomes of our modules without compromising the privacy rights of our students. Open discussions on ethical guidelines and continuous awareness among lecturers and management as well as lecturers and students [are] essential to overcoming these challenges successfully.
All 15 participating lecturers noted that using AI in their blended learning modules was beneficial, but not all believed they were using AI to its full potential, admitting there was room for improvement. Lecturer F stated:
While AI has enhanced certain aspects of my lecturing and interaction with my students, I really feel that there's much further potential for the use of AI in my modules, especially with regard to the advanced AI functionalities and typing in the correct prompts.
Lecturer O opined:
Integrating AI into blended learning helps me improve the actual teaching of the content of my modules. This allows me to individualise the learning experiences of each of my students, to ensure that their needs and preferences are met.
Lecturer A agreed:
Using AI in my blended learning course helps me adapt to my students' needs. This makes the teaching and learning much more flexible and meaningful, as it allows me to develop an individualised teaching approach to each student's strengths and weaknesses.
Nine of the participants highlighted the significance of AI’s prompt feedback to the inputs provided and queries posted on the AI system. In response to interview question 6 ("Have you received any feedback from students regarding their experiences with AI-infused blended learning?"), Lecturer B mentioned,
The quick feedback of AI has really changed the learning experience. Students receive real-time feedback [on] their progress, allowing them to make [the] necessary changes immediately.
Lecturer K echoed this:
I see AI as a game changer. Its ability to offer instant, personalised feedback has been a real […] eye-opener. It helps students understand their strengths and weaknesses without delay. This helps ensure a more integrated and authentic learning environment. It helps in identifying gaps in understanding and adapting teaching strategies.
Lecturer N concurred, adding:
From where I stand, AI's ability to analyse student data can provide valuable insights for personalised teaching and learning, and allows for instantaneous feedback. As a result, students' entire learning process is enhanced, resulting in an improved ability to achieve their learning goals.
Lecturer B, who viewed the instant feedback of AI as beneficial for enhancing teaching and learning, had used AI to create scenario-based feedback activities. The document analysis identified instances where students were presented with virtual scenarios representing diverse language teaching situations, such as classroom settings, one-on-one tutoring sessions, and language immersion programmes. AI was able to instantaneously analyse students' responses and actions in each scenario, providing immediate, real-time personalised feedback on their answers. This integration of AI thus enhanced both asynchronous learning and synchronous F2F interactions, by offering immediate feedback during live sessions.
The interview responses of seven of the participants revealed that AI is able to easily automate administrative tasks, through machine learning algorithms and natural language processing. This analytical capability allows instructional approaches to be adapted to individual student needs, ensuring that they successfully attain the learning outcomes of the module. Lecturer C said:
AI tools can streamline administrative tasks, allowing me to devote more time to my students and support them, especially where they are encountering challenges.
Lecturer F added:
I've used AI to analyse student performance data, which helps me adapt the content of my modules and teaching methods to make them more interactive. This can easily be based on my individual students’ needs.
The document analysis, which aimed to examine evidence of how assessments reflect the unique contributions of AI to student learning outcomes (the fourth criterion on the document analysis) also showed that modules where AI was integrated into feedback mechanisms saw improved student engagement. Studying the module site of Lecturer F, the researchers discovered that s/he used AI to automatically grade assignments (multiple-choice and written) and give immediate feedback. The reports generated were instantaneous and showed specific trends which helped the lecturer adapt the teaching and learning of this particular module.
It is indeed important to note how AI supports F2F teaching in class. As a result of this approach, learning during live lectures is made more dynamic and responsive to student needs. This point was highlighted by Lecturer M, who said:
The use of AI tools allows for instantaneous feedback to my students’ questions during lectures. It can give them various suggestions for additional materials and let them engage in interactive activities during face-to-face classes that will allow them to engage more deeply with the material.
All the participating lecturers confirmed the importance of comprehensive training and professional development. The need for comprehensive training and institutional support emerged as a critical theme. Interview Question 8 ("What kind of training or professional development opportunities do you believe are necessary for lecturers to effectively integrate AI into their blended teaching methods?") prompted responses highlighting the importance of ongoing professional development. In the words of Lecturer G:
Access to ongoing professional development courses focused on AI is essential for us lecturers to keep up to date with the latest developments in this field.
Lecturer M noted:
Professional development should include […] theoretical knowledge of AI as well as, specifically for us, its practical application in blended learning contexts.
Four participants stated that technological support was imperative if AI was to be instituted successfully. Lecturer O suggested:
Dedicated support teams must be specifically set up to assist with any technical challenges we may come across during the implementation of AI into our teaching and learning. This includes prompt responses to technical glitches and troubleshooting, to ensure that everything works properly for both me and my students.
We need assistance with initial setup and implementation, and with ongoing technical issues that may arise. This could be problematic as our IT help desk is already so overburdened. More IT staff definitely need to be employed.
Having institutional support for incorporating AI into the curriculum, is crucial. This involves not only providing resources, but also creating a culture that values and encourages the integration of AI technologies into teaching practices. This was echoed by all the lecturers interviewed. In the words of Lecturer A:
Having institutional support for incorporating AI into the curriculum is crucial. This involves providing resources as well as creating an institution that values and encourages the integration of AI into our teaching and learning.
Lecturer O echoed this:
Institutional commitment is key to the successful integration of AI. This should also include dedicated policies, so that we lecturers know exactly the correct process of AI.
Additionally, setting aside dedicated time for lecturers to adopt AI technologies was deemed imperative, as mentioned by ten of the participants. Lecturer H opined:
Allocating specific time for training and hands-on experience with AI tools is crucial. We need the opportunity to explore and familiarise ourselves with this new, exciting technology. This will definitely help us.
Lecturer E noted:
Having dedicated time for learning and experimentation is essential. This would give us more confidence in the actual implementation. But our schedules are already so busy that I have to wonder if this is at all possible.
Next, we examine the findings of the research.
Using the research findings as a starting point for drawing meaningful conclusions and contributing to scholarly discourse on the subject, this section provides a summary of the findings that correlate with the literature review. From the utterances of many of the participants it became clear that there is a positive attitude towards AI, its significance for blended learning, and the benefits for tertiary students, as long as HEIs make certain adaptations. This aligns with the Redefinition and Modification aspects of the SAMR [ 34 ] model used for this study.
The research questions sought to explore how AI influences student engagement, interaction, and learning outcomes in blended learning environments. Lecturer N’s opinion, that AI boosts the learning process as a whole, resulting in an improved ability to successfully complete the course , is consistent with the findings of Alshahrani [ 3 ], Ferry et al. [ 13 ], Fradila et al. [ 14 ], Rahman et al. [ 37 ] and Santosa et al. [ 39 ], who found that infusing AI into a blended learning module enriches the learning process for students, helping them to achieve the specified learning outcomes. The collaborative and conversational capabilities of AI enhance the overall learning experience, leading to an enjoyment of the course, and active participation by students. These findings support the SAMR [ 34 ] model’s Redefinition level, where AI transforms the learning experience. Accordingly, the researchers of this study recognised that while AI does enhance learning experiences, its integration must be carefully managed to avoid over-reliance on technology at the expense of fundamental pedagogical principles.
The research findings corroborate the potential benefits AI holds for blended learning, as identified by the interviewees. Lecturer H's use of AI for immediate student support aligns with the views of Alsaleem and Alghalith [ 2 ], Alshahrani [ 3 ] and Lee [ 24 ], who emphasise AI’s capacity for personalising learning experiences. Moreover, Lecturer B's opinion on the importance of using AI for the prompt integration of AI-driven feedback, is consistent with the findings of Alshahrani [ 3 ] and Khosravi and Heidari [ 22 ], which emphasise AI’s functionality of supplying instantaneous feedback to enhance the learning experience. This aligns with the Augmentation level of the SAMR [ 34 ] model, where AI enhances existing teaching and learning practices. This made it clear to the researchers that while AI-driven feedback can significantly improve learning efficiency, it also raises concerns about data privacy and the need for transparent feedback mechanisms.
The views of Weber et al. [ 41 ]—that resistance to change may be an obstacle to the effective implementation of AI—are consistent with the opinions of 12 of the study participants. Specifically, Lecturer G noted that transformation is often met with resistance, especially when it comes to technology, and AI may be perceived as a risk to the conventional mode of teaching. Addressing this resistance requires policy interventions and professional development programs to ease the transition and encourage AI adoption. This indicated to the researchers that creating a culture of continuous improvement and gradually embracing this new approach may prevent resistance to adopting AI by lecturers and their higher education institutions.
The perspectives of all the participants, as regards the significance of tailored training and professional development which are customised to their specific needs, align with the findings of Luckin et al. [ 26 ]. According to that study, training should be more specific, and be contextually relevant to the unique demands and settings of the educational environment. This approach encourages active engagement and participation. Lecturer M specifically noted that any related training should focus mainly on its application to blended learning, to be successful. This highlights the importance of ongoing professional development to keep pace with technological advances. Clearly, HEIs need to adapt their policies to integrate AI tools that support personalised and interactive learning experiences. This suggested to the researchers that for AI technologies to be successful in higher education, professional development programmes must be made easily accessible for lecturers.
Finally, as featured in Alshahrani’s [ 3 ] study, the ethical use of AI in educational environments that adopt a blended learning approach, must be considered. Two participants (F and G) expressed the same sentiment, stating that open discussions on ethical guidelines and continuous dialogue among lecturers, management, and students are essential for navigating these issues. This suggests that policy should include ethical guidelines for AI use in education, ensuring that such integration supports not only academic integrity, but also responsible teaching and learning practices. In view of these findings, the researchers concluded that there was a distinct need for the creation of specific ethical frameworks that would assist all stakeholders to address the emerging ethical concerns associated with AI use in higher education institutions.
It is important to note the limitations of this study, which affect the generalisability of the findings. First, the study was restricted to a single South African higher HEI and one specific college, which may limit the applicability of the results to other contexts or institutions. Additionally, the full impact of AI on the blended learning approach may only become apparent in the future, as the students from this cohort progress in their careers and enter their respective professions. Furthermore, AI is a rapidly evolving field, and its continual advancements could mean that the study’s findings might become outdated relatively quickly. Finally, the successful implementation of AI in blended learning modules may be hindered by the lack of requisite technological resources and infrastructure in some educational institutions, potentially affecting the feasibility and effectiveness of AI integration.
This paper discussed the impact of AI on a blended approach to teaching and learning in a particular HEI. It was based on the perceptions of 15 participating lecturers who lecture in the same college, albeit in different departments. The insights were based on the lecturers’ familiarity, experiences of, and involvement with, AI, and its impact on their teaching and learning. This positioned them to discuss the perceived advantages, disadvantages and supportive measures needed for such an approach to be successful. The use of focus group interviews and document analysis enabled the researchers to correlate what was actually taking place in this field of research, with the literature review undertaken.
Puentedura’s [ 34 ] SAMR model was chosen as theoretical framework to guide this undertaking, since it enabled the researchers to investigate how AI could bring about transformative changes in blended learning within the domain of higher education. The results highlight the significance of using AI in hybrid learning contexts, which has great potential for transforming traditional teaching methods. The study highlighted the implications of adopting AI to enhance the effectiveness of blended learning which offers personalised feedback, interactive discussions, and adaptive resources to cater to individual student needs. The findings draw attention to the crucial role of supportive measures such as management backing, improved training and professional development opportunities, reliable technological infrastructure, and improved internet connectivity, in ensuring the successful use of AI for blended learning modules. The findings thus enhance the knowledge base of this emerging field of study, by clarifying the perspectives of the lecturer participants at a particular HEI. Moreover, the findings can support future research on this topic, and may be used by other educational institutions—even those catering for different age groups.
Recommendations for further research include several key areas to enhance the understanding and implementation of AI in blended learning environments. First, investigating AI and blended learning across various HEIs, both within South Africa and internationally, would provide a more comprehensive understanding of lecturers' perceptions of AI's impact. Additionally, research should focus on the effect of AI on students’ achievement of learning outcomes, their engagement with modules, and their overall enjoyment of learning within hybrid environments. Examining specific support measures, particularly relevant training, could further assist lecturers in effectively integrating AI into their modules. Longitudinal studies are also recommended to track changes in lecturers’ perceptions as they adapt to and integrate AI over time. A thorough exploration of the challenges HEIs face during the implementation process should be considered to address potential barriers. Furthermore, research into the ethical implications of AI in education, including the development of necessary guidelines, is essential. Finally, future studies should aim to validate and expand upon these findings using quantitative methods, as this study was purely qualitative.

Case study researchers study current, real-life cases that are in progress so that they can gather accurate ...
Abstract This chapter explores case study as a major approach to research and evaluation. After first noting various contexts in which case studies are commonly used, the chapter focuses on case study research directly. Strengths and potential problematic issues are outlined, followed by key phases of the process. The chapter emphasizes how important it is to design the case, to collect and ...
1.2 Specific Character of the Case Study as Compared to Other Research Methods The case study strategy 1 requires an in-depth and comprehensive analysis of a case within its context. A group, an individual, an organization, a processes, or social relationships can all be considered "cases" and, as such, be subject to research. It is advisable to begin by imagining the case as an example of ...
A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research. A case study research design usually involves qualitative methods, but quantitative methods are sometimes also used.

This article reviews the use of case study research for both practical and theoretical issues especially in management field with the emphasis on management of technology and innovation. Many researchers commented on the methodological issues of the case study research from their point of view thus, presenting a comprehensive framework was missing.
The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design ...
A case study is an in-depth investigation of a single person, group, event, or community. This research method involves intensively analyzing a subject to understand its complexity and context. The richness of a case study comes from its ability to capture detailed, qualitative data that can offer insights into a process or subject matter that ...
Definition of the Case Study. "An empirical inquiry that investigates a contemporary phenomenon (e.g., a "case") within its real-life context; when the boundaries between phenomenon and context are not clearly evident" (Yin, 2014, p.16) "A case study is an in-depth description and analysis of a bounded system" (Merriam, 2015, p.37).
A case study relies on multiple sources of evidence, with data needing to converge in a triangulating fashion." 1(p15) This design is described as a stand-alone research approach equivalent to grounded theory and can entail single and multiple cases. 1,2 However, case study research should not be confused with single clinical case reports.
How to Design and Conduct a Case Study. The advantage of the case study research design is that you can focus on specific and interesting cases. This may be an attempt to test a theory with a typical case or it can be a specific topic that is of interest. Research should be thorough and note taking should be meticulous and systematic.
Researching Employee Absenteeism Using the Case Study Method Professor W. Tad Foster presents a case study that addressed an employer's concerns about absenteeism. Researching Innovation in Qualitative Research Using In-depth Case Studies Professor Melanie Nind discusses innovation in research methods and what it means to innovate.
The researchers applied a singular case study research design. This involved focusing on a single participant or unit of analysis, for an in-depth exploration of the intricacies and dynamics of a specific case . This approach made it possible to conduct a thorough examination of the perceptions of lecturers employed in the College of Education ...
