Although the implementation of blended learning in organic chemistry is rapidly growing, thus far, there are few studies published on the evaluation of supplemental types of blend in organic chemistry. This report covers a phenomenographic study that was designed to evaluate a supplemental type of blended learning approach implemented in a second-year organic chemistry course in a South African context. It offers a unique contribution in terms of catering to the needs of a diverse student body. Three open-ended questionnaires were used to probe: (1) students’ perceptions of the learning support; (2) students’ preferences for different types of learning support offered; and (3) students’ suggestions for improvement. Semi-structured individual interviews were used to obtain clarity on some of the responses from the questionnaires. Analysis of students’ responses revealed that the face-to-face component was highly valued as it gave the students the opportunity to ask questions and obtain answers in real time; the online component, especially Learnsmart, was found helpful for its flexibility and providing limitless opportunities to practice or revisit concepts. The discussion board was the least valued due to the overwhelming number of postings, and the students felt they were forced to participate in order to get marks. The students experienced the course as too fast-paced possibly reflecting cognitive overload, a potential weakness of the supplemental blend. The findings will be useful in many other contexts where the student body is diverse in terms of language proficiency and the level of preparation for the demands of organic chemistry as a discipline.
South Africa is known as the Rainbow Nation because of a diversity of culture, race, ethnic groups, religion, heritage and tradition. This diversity is also represented in the second year organic course in terms of race, home language, schooling systems (rural, township and city schools are reflected which represent a wide variety in the quality of the students’ high school education), access to computers and the internet. In order to have access to online learning opportunities, students were expected to have a tablet or laptop, and internet access. Although 91% of the students enrolled in the second year organic course owned either a tablet or a laptop, only 39% had uncapped access to the internet during school term; 49% had limited access during school term; and 12% did not have access to the internet during school term. The students without internet access had to therefore complete the online components of the course on campus where free access is available.
Seeing that teaching and learning is such a complex phenomenon, we set out to determine which aspects of the blended learning approach were most conducive to learning by looking into students’ perceptions of the affordances and hindrances associated with it. Therefore, our aim was to evaluate the blended learning approach implemented for the theoretical component of the second year organic chemistry course. In order to achieve this goal, we decided to explore students’ perceptions and preferences of the learning support provided as part of the blended learning approach. By describing the full range of experiences and perceptions, we will reveal the affordances and hindrances of the supplemental type of blending; and we may be able to see if such a blend is an equitable offering.
According to Twigg (2003), a blended learning approach can be categorized as one of the following models, namely, replacement model, supplemental model, emporium model and buffet model. The replacement type of blending involves the partial or full substitution of face-to-face lectures by online learning opportunities hence resulting in the reduction of the number of face-to-face classes. Contact lectures are often replaced by videos of the lecture posted online. Since face-to-face lectures are moved online, class time meetings are usually used for answering lecture related questions and engaging in problem solving activities. The supplemental type of blending retains normal class meetings; however, additional learning resources are made available online. Students are required to make use of the additional technology-based learning resources either for preparing for class, homework, or further engagement with course content. The supplemental type “helps strengthen course input and motivate students who may be falling behind,” (Derbel, 2017, p. 144). In contrast, the emporium type of blending is structured in such a way that face-to-face class meetings are replaced with a learning resource center “featuring online materials and on-demand personalized assistance,” (Twigg, 2003, p. 34). This type of blended learning approach is dependent on instructional software including interactive tutorials, computational exercises, electronic hypertext books, practice exercises, solutions to frequently asked questions and online quizzes. The buffet type of blending is flexible in a sense that it provides various face-to-face and online learning activities, and students choose any combination that suits their needs, lifestyle or schedule. In the current study, the course design fits the supplemental model of the blended learning approach, that is, it consisted of a combination of traditional face-to-face learning with additional learning resources/learning supports made available online.
The majority of reports published in chemistry have concentrated on the replacement type of blending (usually referred to as flipped instruction) in which face-to-face lectures are either partially or completely replaced by online lectures. Research on the implementation of flipped instruction in chemistry falls mainly into two categories. The first type of studies investigated the influence of the flipped approach on student performance via comparison of student grades and/or class averages before and after the implementation of the flipped instructional approach (Fautch, 2015; Flynn, 2015; Weaver and Sturtevant, 2015; Yestrebsky, 2015; Mooring et al., 2016; Reid, 2016; Ryan and Reid, 2016; Cormier and Voisard, 2018). The second category of research concentrated on the evaluation of the flipped instructional approach through student surveys and course evaluations (Smith, 2013; Flynn, 2015; Mooring et al., 2016; Ryan and Reid, 2016). Very few studies conducted in chemistry, specifically organic chemistry, have focused on the supplemental type of blending in which face-to-face lectures are supplemented with additional online learning supports (Brown et al., 2012; Ryan, 2013). In his study, Ryan (2013) aimed to evaluate the effectiveness of using three technologies (Peer Learning Technology, Personal Response Devices and PeerWise) to promote peer learning. Results revealed that the students’ evaluations of the technologies were mainly positive thus indicating that students enjoyed using them. The technologies also assisted in improving student engagement and activity in and outside class. Brown et al. (2012) supplemented lectures with videos and animations in order to help students learn and understand mechanistic organic chemistry. Students reported that the use of online learning resources improved their understanding and ability to confidently apply mechanistic knowledge.
In this article, we describe students’ perceptions and preferences of a supplemental type of blended learning implemented in a second year organic chemistry course. The following research questions were addressed: (1) What are students’ perceptions of the learning support provided as part of the blended learning approach? (2) What are students’ preferences for the learning support provided by the blended learning approach? (3) In what ways, if any, do the students think the blended learning approach can be improved? Asking students to stipulate their preferences, and areas of improvement will help us to better understand the strengths and weaknesses of the supplemental type of blended learning approach, that is, it will inform us about the components of the blended learning approach that students found conducive for learning and those that were not conducive for learning. Learning support incorporates face-to-face lectures, face-to-face tutorials, and online learning resources.

The traditional course lacked meaningful formative assessment opportunities because of a shortage of tutors/teaching assistants and funds to pay them, so all feedback through the grading of tests came from the lecturers resulting in significant delays, such that the next theme was already completed before students received feedback. In 2016 the lecturers decided to implement the supplemental type of the blended learning approach with the aim of giving students access to real-time individual personalized feedback. Although the supplemental blend has the inherent risk of overloading students by adding more activities without taking anything away, this implementation represented a conservative approach, not taking away the face-to-face contact we thought that our traditional students would need. To introduce a meaningful blend of face-to-face and online learning opportunities each activity was considered for the value it would add to learning. Given the risk of overload, it was important to evaluate each learning opportunity for the value experienced by the students.
In 2017 Learnsmart assignments were used to encourage preparation for class through reading of the appropriate sections of the textbook before the work was discussed in class. However, informal student feedback suggested that Learnsmart was not being used for lecture preparation, instead students found the tool useful for enhancing conceptual understanding. Hence, in 2018, the motivation of the use of Learnsmart (Appendix 1) as presented in the course study guide was changed with Learnsmart being described as a tool to learn to read academic texts for conceptual understanding.
In 2018 we decided to advocate the discussion board activities as the “development of language skills” rather than for lecture preparation based on our observation that it was being used more after the class than in preparation for class. Furthermore, we felt that the most important gain from the discussion board in 2017 was the improvement in the students’ ability to verbalize chemistry because the discussion board did not readily cater for the use of chemical drawings. We hoped that the changed motivation for the use of the discussion board (Appendix 1) would change student's expectations and would answer to the general student request to use a forum that could incorporate chemical structures.
Phenomenographic analysis aims to qualitatively identify the various ways in which participants perceive or experience a phenomenon (Marton, 1981; Orgill, 2007). Consequently, during data analysis, our aim was to identify the different ways in which the students experienced or perceived the blended second year organic course. Transcriptions were read a number of times in order to understand and become familiar with them. This was followed by the initial generation of codes that addressed the proposed research questions. Labels used for the generated codes were either directly from the data or from the researcher's mind (Strauss and Corbin, 1998). The initial coding was followed by comparing the generated codes with each other and their supporting data in order to combine similar codes to form overarching themes that portray students’ perceptions of the course (Strauss and Corbin, 1998; Braun and Clarke, 2006). This was followed by refining the generated themes. During the process of refining the themes, excerpts of themes were read in order to check if they formed a “coherent pattern” (Braun and Clarke, 2006). In cases where some data excerpts did not form a coherent pattern with the rest of the data excerpts, such excerpts were moved to other themes. Once the refinement of themes was done, data excerpts under each theme were read in order to provide a detailed description of what each theme revealed regarding students’ perceptions of the course. In phenomenographic data analysis, it is important to ask “what does this tell me about the way the participants understand the phenomenon?” (Rands and Gansemer-Topf, 2016, p. 12). Similarly, during the analysis of data, the researchers continually asked the same question, that is, “What does this tell me about students’ perceptions and preferences of the course?” It is important to state that the generation of codes, development, and refinement of themes was halted once theoretical saturation (Bowen, 2008) was reached. That is, coding of data from the 39 participants was stopped once the researchers realized that there were no longer any new themes that emerged from the data.
In addition to providing a rich detailed description of the study setting and participants, peer debriefing (Creswell and Miller, 2000) was also employed to establish the credibility of our findings. That is, the codes were developed and refined by two of the co-authors and the third co-author confirmed the coding and descriptions of the themes.

Themes | Examples of student quotations |
Discussion platform | “I find the discussion board very helpful, seeing as we can ask for help on specific concepts. It also enables us to answer fellow students and demonstrate that we understand our work […].” |
“On the discussion board you also get the option to share your opinions with one another and it's nice to see how the people interpret the things as well.” | |

One interesting aspect to point out is that although the majority of the students in 2018 did not find the discussion board to be helpful, pilot data collected in 2017 (Table 3c) showed that the participating students liked the discussion board because it gave them the opportunity to confirm their knowledge through answering other students’ questions, and writing theme-summaries. Other students appreciated the discussion board because it provided a platform where they could ask questions, discuss answers and see how other students thought about concepts.

The second main finding of this study is students’ preference for face-to-face lectures and tutorials because these provided student-lecturer interaction which allowed students to ask questions and obtain answers in real time, and also gave the lecturer the opportunity to explain concepts thoroughly. A number of studies into students’ perceptions of blended learning have reported that although students favoured the online components of blended learning (Chen and Jones, 2007; Akkoyunlu and Soylu, 2008; Chandra and Fisher, 2009) they also valued face-to-face interaction as an important part of learning. The reason being in face-to-face interaction, instruction is clearer (Chen and Jones, 2007), and they are given the opportunity to ask questions and receive immediate feedback (Akkoyunlu and Soylu, 2008; Chandra and Fisher, 2009; Horn, 2013). Giving students immediate feedback is considered to be one of the seven principles of good practice in undergraduate education (Chickering and Gamson, 1987) as it (i) improves students’ self-awareness and confidence (Horn, 2013); (ii) assists lecturers to monitor individual progression (Cormier and Voisard, 2018); (iii) and helps “reduce the gap between current and desired understanding” for students (Hattie and Timperley, 2007, p. 86).
The third main finding of this study is that the discussion board was the least preferred of the range of learning opportunities offered. The reasons given for it not meeting their needs could provide insight for improving the offering and for blended course design. About a third of respondents indicated that the discussion board did not meet their learning needs without expanding on the details. The second most frequent reason given for not preferring the discussion board was that they did not know how to use it. One tends to make the assumption that 21st century students will navigate their way through e-platforms without assistance, but this should not be taken for granted in a class from diverse backgrounds. The discussions became unstructured with questions and answers being separated reflecting the students’ uncertainty of how and where to make a contribution. The introduction of a few short instructions at the point of use e.g., “to ask a question or post a summary ‘reply’ to the relevant topic; to answer a question ‘reply’ to the question,” could address this need. It also became clear that discussions with many participants got messy when not tightly managed to avoid postings under wrong headings and duplication of content. The third most common complaint indicates that balance is needed in using marks to encourage engagement versus controlling participation. In the course design, the discussion board was meant to be an alternative to Learnsmart. Students were required to make one contribution to qualify for the full 5% in order to encourage them to experience what the discussion board has to offer. Several students expressed the view that the discussion board should not be for marks which indicates either that they had not understood that the discussion board and Learnsmart were meant to be alternatives or that they resented the requirement to make at least one contribution. Deadlines were not as tightly managed for the discussion board. It is therefore possible that some students made use of the opportunity simply to gain marks by participation in the discussion when they had missed the deadlines to complete Learnsmart assignments. This participation led to the fourth reason given for not preferring the discussion board: the number of posts was overwhelming. The number of new posts would have been particularly daunting to intermittent users or first time visitors to the discussion board because time is required to read the postings, think about a response, prepare a response, and examine responses from other students (Ryan, 2013). As one student recommended, a regular group of more committed participants could have transformed the discussion board into a more useful learning platform. Therefore, when using discussion forums in blended learning courses, there is a need for lecturers to provide clear instructions regarding what they expect from students; motivate the students to participate constructively in the discussion; provide constant feedback; and organize the discussions in such a way that students will find it easy to find useful information at a later stage (Roper, 2007). The fifth significant concern expressed by a few students was that they did not have confidence in the validity of the contributions of their peers. While lecturers did correct content behind the scenes, there was no obvious endorsement of answers by the lecturers. In a small class, students might know the other class members and be able to recognize contributions coming from stronger students as trustworthy, but this was not the case for this course. If an environment could be created where mistakes are valued as learning opportunities and openly corrected by lecturers with sensitivity and appreciation, there could be great learning gain. The effectiveness of the discussion forum is influenced by the lecturer's involvement “especially in the form of technical support, providing constructive feedback, and setting clear expectations to help students understand what is expected of them,” (Mokoena, 2013, p. 97). Offering feedback provides evidence to the students that the lecturer is interested in their comments, (Mokoena, 2013). Despite the lack of preference for the discussion board as a learning opportunity in the 2018 study, the pilot study showed that some students did find the discussions useful for peer learning from the questions and answers of others; and through the discipline of summarizing the work for the benefit of others. This suggests that there is value in providing a selection of different activities and allowing students to choose to use those that best suit their needs.
The consistent rating of the discussion board as the least preferred learning support in 2018 came as a surprise given that it had received some positive endorsement in 2017 and there had been no negative comments. There were two changes in implementation from one year to the next: (i) how it was advocated in the study guide with a corresponding change in the title for the marks earned – “Professional Development Points”; and (ii) the marks earned were regularly updated on the LMS with students being reminded not to forfeit the opportunity to earn marks through either doing Learnsmart or contributing to the discussions. The number of contributions in the discussion forums for themes 4, 5 and 7 were substantially higher in 2018 compared to 2017. Comments from students that participation was “forced” taken together with the observation that participation increased suggests that the regular reminders and updating of marks had a bigger effect on the student experience than how it was advocated in the study guide. It appears that participation for the purpose of collecting points rather than learning may have led to lower quality contributions, overcrowding of certain themes and loss of structure. This had a detrimental effect on the overall learning experience.
The fourth main finding is that students were not satisfied with the format of the course. They suggested that the course should be offered over a semester (14 weeks) rather than quarterly (7 weeks); the pace at which the course is taught should be slowed down; more tutorial sessions should be offered; and participation in the discussion board should not be marked. Students might have suggested these improvements because they believe these will create a better learning environment. For instance, if the course is offered as a semester course, the students will have more time between classes to digest the work taught. Exposing students to too much information too quickly is a disadvantage because the human information processing system has limited capacity (Mayer and Moreno, 2003). These comments also suggest that the supplemental blend may be overloading the students, but without it, those without good self-regulation skills would fall behind in such a challenging fast-paced course.
Lastly, we had anticipated that the learning experience of students with English as a second language might have differed from the experience of English speaking students, but language issues did not feature in the students’ responses. This might be because the questionnaires were not designed to probe for such differences. It is also possible that because the lecturers were aware of and sensitive to the needs of second language students, the language of instruction was not a primary obstacle to learning.
Although students found the delivery of the course very demanding, the composition of the blend was validated as all components of the blend were endorsed by at least some students. It is beneficial to make a range of learning resources available in the supplemental model and students be given the flexibility to choose to use the supplemental support that serves their individual learning needs best so that they are not overloaded with learning resources. However, apart from providing a range of learning resources, we recommend that lecturers should advocate for their potential value, and students should be required to engage with each type of resource at least once in order to make an informed decision about how best to use their time. In addition, in the supplemental model assignments should be kept short or in the case of the discussion board constructive participation should be encouraged and rewarded, and it should be better structured to ensure that relevant content is found quickly.
In this study, the views of students representing diverse backgrounds were captured. The study was conducted in the context of a student body from diverse backgrounds in terms of language diversity, with the majority of students learning in their second language, and prior exposure to technology. This group endorsed the face-to-face component thus verifying that the conservative choice to implement a supplemental type of blending was best suited to their needs. For second language speakers the language demand of reading constitutes additional cognitive load. In this study all online support depended on reading in English. The most preferred online learning support was Learnsmart which guided students in reading the textbook. This matches our expectation that second language students would appreciate this resource and that it would help them make sense of the textbook. Some of the reasons given for not liking the online activities reflected the discomfort of some students in working with technology.
The study has several limitations which could impact on the generalizability of the findings, namely the limited size of the sample, and the unique context within which the study was conducted. Although the participants in this study represented students from diverse backgrounds, the study did not reveal how different demographics influenced the perception of each learning support. More data would have to be collected to address this matter. However, despite these limitations, our study provided powerful insights to inform the improvement of the second year organic course for future students. We anticipate that the findings will be useful in other contexts where the student body is diverse in terms of language proficiency and the level of preparation for the demands of organic chemistry as a discipline.
Learnsmart is an online tool that is designed to help students to read the textbook and understand core concepts by linking conceptual questions with the text book. This is not the same as learning procedures for solving test and exam problems. To get the most out of Learnsmart, you should make sure you understand the answers entered and not just look for keywords in the text. We would recommend that you use this tool if you find the textbook overwhelming or you aren’t used to using textbooks. Each completed Learnsmart assignment earns you 1 Professional Development (PD) point. There will be 11 Learnsmart assignments.
The Discussion Board on ClickUP is used to help you to develop the language skills for Organic Chemistry. Since the Discussion Board does not accommodate chemical drawings, you will need to use scientific English to describe chemistry. Fluent scientific language is necessary for job interviews, scientific discussions and presentations. There are three ways to make a contribution on the Discussion board:
• formulating meaningful questions about what you don’t understand;
• using references to the textbook in answering another student's question on the discussion board in a meaningful manner that involves interpretation of material from the textbook to make it more understandable for a fellow student;
• writing a summary of a topic.
Each quality contribution on the Discussion forum counts 1-PD point. To encourage you to stay up to date with the work in order to be ready for the next topic, the discussion forum for each theme will close at the end of each study theme. We recommend that you use this tool to help you develop your language skills. It is also really useful to put in words what you don’t understand or what you think you understand as this makes it clear where you need to focus your attention to improve your marks.
You will be expected to complete at least one Learnsmart assignment and make at least one quality contribution on the Discussion Board. To earn the full 5% professional development mark, you must have 12 PD points. The 12 PD's can be made up from a random combination of Learnsmart Assignments and Discussion board contributions. Fewer contributions are awarded fewer marks as follows: 12 or more = 5%; 10–11 = 4%; 7–9 = 3%; 5–6 = 2%; 3–4 = 1%; 2 or less = 0%.
