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.
Higher education institutions have a constitutional obligation to provide reasonable accommodation to students with disabilities. Although the teaching and learning of students with blindness and low vision in STEM disciplines are well documented abroad, to date, there are no published studies in South Africa on successful teaching and learning strategies for students with blindness and low vision in STEM fields, specifically in science disciplines. Therefore, in this paper, we report on how teaching, learning, and assessment were adapted to make science disciplines accessible to John, a blind student enrolled in a biological sciences degree at a research-intensive university in South Africa. Several factors contributed towards the successful completion of John’s bachelor’s degree. These factors include the availability of tutors who committed a large amount of time to help John understand content presented in lectures, tutorials, and practical sessions; a well-resourced and effective Disability Unit; lecturers who ensured that John was well accommodated in lectures, tutorials, and practical sessions; and, finally, John’s commitment and dedication towards learning.
Student protests are a regular feature of the tertiary landscape. However, there are claims that disruptions and potential threats to the academic project at traditional universities can be partially mitigated by online teaching and learning. This paper reports on insights gained when the mode of instruction was changed at short notice from contact to online teaching during student unrests at a South African university in 2016. A phenomenographic approach was used to generate a meta-reflection on experiences as reported by lecturers from 13 science departments during a pecha kucha 1 event (very short PowerPoint presentations) at the beginning of 2017. Video data was analysed inductively to generate six themes/categories, encapsulating aspects of the challenges experienced by the participants, the insights they had and the actions they took to address these challenges. This paper attempts to demonstrate the approaches taken by lecturers and how they incorporated the blended learning environment to support their students to complete the academic year, despite difficult circumstances. It offers useful pointers to affordances and weaknesses of the virtual learning environment when implemented at short notice to replace contact teaching.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
