This study aims to describe the reduction in student misconceptions regarding Newton's Laws after remediation using student worksheets based on cognitive conflict. The research method used is a pre-experimental design with a One Group Pretest-Posttest format, involving 102 students from three classes at SMAN 12 Surabaya. Data collection was carried out through pretest and posttest, each consisting of five-tier format questions. Data analysis was assisted by SPSS version 25. The significance of the reduction in misconceptions was analyzed using the Wilcoxon test and the Kruskal-Wallis test, as the data were not normally distributed. The results indicated: 1) a significant improvement in understanding between the pretest and posttest, with a high categorization, and 2) all three classes showed comparable improvements in understanding. Based on these findings, it can be concluded that students experienced a significant reduction in misconceptions following remediation using student worksheets based on cognitive conflict.
