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.

Resumo: Neste trabalho, descrevemos uma atividade associada à temática biodiesel desenvolvida junto a uma turma de segundo ano do Ensino Tecnológico. O objetivo foi trabalhar alguns conceitos de Química Orgânica e a associação desses com o meio ambiente ressaltando a discussão na produção de biocombustíveis. Buscamos como base para a metodologia de ensino os momentos pedagógicos propostos por Delizoicov e Angotti  (1991), por permitirem a realização de diferentes atividades. Para avaliar e validar esta prática, foi aplicado um questionário ao final, através do qual pode se destacar que a proposta é uma interessante estratégia de ensino na aproximação entre a ciência e problemas sociais e ambientais. Palavras-chave: Biodiesel. Ensino. Química Orgânica. Biodiesel: an experience from students of Technological Education Abstract: In this study, we describe an activity related to the biodiesel subject which was applied to a second year class of Technologial Education. The goal was to work on some Organic Chemistry’s concepts and its association to the environment emphasizing the discussion in the biodiesel production. We propose as teaching methodology the pedagogical moments proposed by Delizoicov & Angotti  (1991), which enable different activities to be done. A questionnaire at the end of the activity was filled out by the students in order to evaluate this approach, which validated the activities done as an excellent approach for teaching students to assign the science to the environment and social issues.

The Subject

Chemistry subject continues to be considered as difficult to teach and learn. This leads to students’ low academic achievement, retention, and negative attitude towards the subject. Organic chemistry as one of the concepts on which technological advancement is constructed sometimes appears to be enormously complex to students. There are some persisting misconceptions about it although different innovative instructional strategies have been applied and this area is of main concern as the learning of students can be extremely hindered in case their misconceptions are not minimized and/or corrected. The review then is to equip educators with knowledge about organic chemistry concept and source of students ‘misconceptions; the misconceptions of students about organic chemistry; the ways of diagnosing students’ misconceptions and remedies of those misconceptions; some learning theories for the effective organic chemistry instruction and classroom implications. The paper is also useful to know more about the minimization of students’ misconceptions and leading them to the great academic achievement and interest towards the subject by employing cooperative learning models; thus, many other different innovative teaching strategies are recommended to apply in organic chemistry instruction
