The Impact of Practical Learning Methods on Physical and Chemical Changes of Student Academic Achievement at SMP Negeri 3 Cikancung
Main Article Content
Abstract
Science education in junior high school continues to face difficulties in improving student learning outcomes, especially in physical and chemical changes topic. This study aims to assess the effectiveness of the experimental learning method in improving student learning outcomes at SMP Negeri 3 Cikancung. The method used in this study is a quantitative approach with a One Group Pretest–Posttest design. Data were analysed using non-parametric statistical tests and N-Gain value calculations to measure the improvement in students' learning outcomes. The normality test showed that the data were not normally distributed, with a p-value of 0.000; therefore, the analysis was continued with the Wilcoxon test. The analysis results showed a significant difference between students' initial and final scores, with p = 0.000. The average final scores of the students increased, with a N-Gain percentage of 78.11%, which is considered high. This finding indicates that implementing experimental methods for the topic of physical and chemical changes is effective in improving students' learning outcomes. This research makes a significant contribution to the development of more innovative teaching methods in science education at the junior high school level.
