ABSTRACT Background Much of the research into the use of drama in science education has been qualitative, with its primary focus being on its affective value amongst students aged 6–14 years, with a smaller fraction on effectiveness in terms of academic achievement and understanding of chemistry amongst older school students (16–18 years). Purpose This article reports on a study that compared the effectiveness of drama, as a pedagogy, with a didactic practice-examinations-questions-based approach on students’ understanding of chemistry organic reaction mechanisms as measured by examination question scores. Sample Data were collected in seven 11–18 schools and a Further Education (FE) college in England, with a total of 236 students, aged 16–18 years, studying Advanced (A) Level chemistry. Each institution had two different classes studying chemistry concurrently. Design and methods The research was a quasi-experimental intervention with one class of A Level chemistry students in each institution being taught an aspect of organic reaction mechanisms using drama and the second, non-drama, class being taught the same material using practice examination questions. Post-intervention, all students completed previously unseen A Level examination questions and, in one phase of the study, a diagnostic question designed to probe deeper understanding. The responses were subject to statistical analysis. Results In all cases there were no statistically significant differences between the test scores of the two groups for the answers to the examination questions. However, answers to a diagnostic question, probing deep level understanding, showed a statistically significant difference between the two groups in favour of the drama group. Conclusions Whilst drama is at least as effective as the use of practice examination questions in the teaching and learning of organic reaction mechanisms it was statistically significantly more effective in terms of the development of deeper level conceptual understanding.
