Abstract

This study aims to determine the effectiveness of the Virtual PhET-assisted Discovery Learning model in improving students' science process skills on collision material. This study uses a quantitative approach with a quasi-experimental method and a non-equivalent control group design. The research sample consisted of 40 students of grade XI MAN 1 Pamekasan who were divided into an experimental class and a control class, each consisting of 20 students. The sampling technique used cluster random sampling. The research instrument was a multiple-choice science process skills test consisting of a pretest and a posttest. Data analysis used the Shapiro-Wilk normality test, homogeneity test, Mann-Whitney test, and N-Gain test. The results showed that the posttest significance value in the Mann-Whitney test was 0.000 < 0.05, indicating that there was a significant difference between the experimental class and the control class after being given treatment. In addition, the results of the N-Gain test showed that the experimental class obtained an average of 91.33% with an effective category, while the control class obtained an average of 59.58% with a fairly effective category. Based on these results, it can be concluded that the Virtual PhET-assisted Discovery Learning model is effective in improving students' science process skills on collision material.

Abstract

This Classroom Action Research (CAR) aims to improve the mastery of physics concepts of Work and Energy material for class XH students through the Discovery Learning model assisted by PhET Simulation media. The main problem in this study is the low mastery of concepts due to conventional learning and limited physical laboratory facilities. Through three cycles of action with the Kurt Lewin model on 36 students, the results of the study showed a linear increase in the class average score from 64.44 (pretest) to 81.51 (cycle III). The percentage of classical completeness also increased significantly from 38.89% to 100.00% at the end of the cycle. The decrease in the standard deviation to 6.42 proves the reduction in the gap in understanding between students. It is concluded that the integration of PhET Simulation with the Discovery Learning model is effective in visualizing abstract concepts, encouraging independent exploration, and optimizing students' cognitive learning outcomes.
