Upaya Meningkatkan Pemahaman Konsep Peserta Didik Pada Materi Pemanasan Global Melalui Model Discovery Learning

This study aims to measure the effectiveness of the Discovery Learning model in improving students' concept understanding of global warming material in class X of one of the high schools in Kotagede, Yogyakarta. This study used a quantitative research design with a sample of 10 learners selected through purposive sampling. The method involved two meetings, each allocated 2 x 35 minutes, which included a pretest, learning by applying the Discovery Learning model, and a post-test. The paired sample t-test analysis showed a significant increase in concept understanding, with the average pretest score of 65.5 increasing to 83.0 in the posttest. The Discovery Learning model's application improved student engagement and understanding of global warming material. Based on the results of this study, the Discovery Learning model is recommended to be applied in physics learning in high school.
