This study investigated the effects of multimedia and dynamic classroom integrated instruction (DCII) on students' academic achievement in two biology topics, i.e., respiration and photosynthesis. A non-equivalent, quasi-experimental design with a mixed research approach was employed. A total of 94 secondary school students participated in the study. Data were collected using biology achievement tests, classroom observations, and focus group discussions. The data was analyzed using paired and independent sample t-tests, repeated measure analysis of variance, and thematic analysis. Using the Kuder Richardson −20 (KR-20) formula, the calculated reliability coefficient of the BAT was .78. The results revealed that in the pretest and posttests, there was a statistically significant difference in biology achievement within the experimental group (t 47 = −17.461, p = .000) and in the posttest between the comparison and the experimental group (t 92 = 5.39, p = .000). Multimedia and DCII is a crucial factor that significantly enhanced academic performance between pretest and posttest scores (time effect), regardless of learning style. Still, there is no significant score difference between the three learning style groups, irrespective of time, and does not interact with each other. In conclusion, multimedia and DCII address the needs of diversified classroom learners, create a more active learning environment, simplify complex content, make the classroom busy, buffer educational inequality between learners, and replace unpractical lab activities. Mainly for abstract content, implementing systematic multimedia-based pedagogy can enhance students’ achievement. |
