Summary:

This study was designed to explore the effectiveness of the 7E instructional model in teaching the concept of factors affecting the rate of chemical reaction to ninth-grade chemistry students in one of the schools in Bhutan. The research design was quasi-experimental, and the study was conducted over a month. Quantitative data was collected from 62 students using convenience sampling, with 31 students each in the experimental and control groups. In addition, a purposeful sampling method was used to gather qualitative data from six students specifically chosen from the experimental group. Quantitative data for the study was obtained using the test and survey questionnaires, whereas qualitative data was collected using semistructured interviews. The test scores underwent descriptive and inferential analysis, while the survey questionnaires were subjected to mean and standard deviation calculations. Thematic analysis was used to analyze the semi-structured interviews. The study found a significant mean difference in the academic scores of students in chemistry when taught using the 7E instructional model compared to the lecture method. Likewise, the study found students exhibited positive attitudes toward chemistry when exposed to the 7E instructional model. Moreover, the study revealed a significant strong correlation between students’ attitudes and test scores. The findings suggest that the 7E instructional model enhances students’ academic performance and fosters a more positive attitude toward learning chemistry. The researchers recommend adopting the 7E instructional model, as it offers a more engaging learning experience that enhances students’ understanding and application of scientific concepts.
