Characteristic Analysis of The Discovery Learning Model in Chemistry Learning of Grade X High School Students in Padang Sidempuan

Abstract

This research analyzes the effectiveness of the Discovery Learning learning model in increasing the understanding of chemistry concepts in class X students at a High School in Padang Sidempuan. Using a quantitative approach with a descriptive-analytic design, this research involved 100 students selected through purposive sampling. The research results show that Discovery Learning significantly increases students' understanding, as evidenced by the increase in the average post-test score from 56.4 to 78.3 and the paired t-test results (p-value = 0.001). Students also demonstrated positive perceptions of the model, with a mean score of 3.73, reflecting increased motivation, active engagement, and critical thinking skills. However, challenges in time management during the implementation of Discovery Learning require further attention. Discovery Learning proved effective in secondary school chemistry learning, with important implications for curriculum development and teaching strategies.
