Abstract
In this study, green chemistry experiments have been used as learning events in the dual-situated learning model (DSLM), and the effectiveness of green chemistry-based DSLM in reducing misconceptions and improving understanding of acid–base concepts was measured. A total of 59 15-year-old Form 2 (equivalent to grade 8) students participated in the study that used a quasi-experimental design involving two groups, namely a comparison group (N = 29) and an experimental group (N = 30). A two-tier Acid and Base Diagnostic Test (ABDT) was used to measure misconceptions on acids and bases held by the students. One-way analysis of covariance (ANCOVA) was performed on the post-test scores with pre-test scores as covariates. The post-test mean score of the experimental group (M exp = 53.23; SDexp = 9.42) appears to be higher than the comparison group’s post-test mean score (M com = 49.59; SDexp = 10.20) and the difference between the mean scores was significant (F (1, 56) = 24.69, p < 0.05). The findings of the study indicate that green chemistry-based DSLM resulted in reducing students’ misconceptions and improving understanding about acids and bases.
