Integration of motion diagram based module to improve students’ conceptual understanding of 1 dimentional kinematics

This study aims to see the effectiveness of using motion diagram-based module to improve students’ conceptual understanding of 1D Kinematics. We have integrated module in online learning during the COVID-19 pandemic. This research was an experimental research with one group pretest-posttest design. The research was conducted on 36 first year Physics undergraduate students. The research instrument consisted of 14 reasoned multiple choice questions. Data analysis was performed using paired sample t-test, N-gain, and d-effect size. The results showed that t = -47.81 [df = 35; sig.(2-tailed) = 0.000] so it can be concluded that students’ understanding of concepts is significantly different. The results of N-gain = 0.543 indicate that the increase is in the upper medium category and the d-effect size = 2.189 indicates that the influence of learning has a strong effect on increasing students’ conceptual understanding. The results of this study indicate that the use of motion diagram-based module can improve students’ conceptual understanding of 1D Kinematics. The students’ conceptual understanding that increased the most significantly was related to compare the velocity of two objects moving in opposite directions. But, many students still have difficulty in determining the instantaneous velocity from the x-t table.
