Abstract

This study aims to determine the effectiveness of using web-based interactive multimedia with feedback on conceptual understanding of rotational equilibrium and dynamics. The data collection method used a quasi-experimental design with a pretest-posttest control group design. The sample used in this study were 30 students in the control class and 30 students in the experimental class, who had studied rotational equilibrium and dynamics. Data analysis techniques used descriptive statistics calculations, independent-sample t-tests, effect size, and N-Gain. The results of the independent-sample t-test obtained p = 0.000 <α = 0.05, indicating a difference in conceptual understanding between the control and experimental groups. The effect size value of d = 0.85 is categorized as high, meaning that the score of the group using web-based interactive multimedia significantly influenced students' conceptual understanding compared to the score of the group that did not use web-based interactive multimedia. Meanwhile, the N-Gain value of 0.31021 indicates that the increase in pretest and posttest scores is in the moderate to upper range. This indicates that the effectiveness of using web-based interactive multimedia programs with formative feedback can improve students' conceptual understanding.
