Improving Student Learning Outcomes through the Discovery Learning Model on the Basic Laws of Chemistry Material in Class X E2 of SMA Negeri 1 Palu

Abstract

This study aims to improve student learning outcomes through the application of the Discovery Learning model on the Basic Laws of Chemistry Material in Class X E2 of SMA Negeri 1 Palu. The research employed Classroom Action Research (CAR) conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. The participants were 36 students of Class X E2. The participants were 36 students of Class X E2 of SMA Negeri 1 Palu. Data were collected through activity observation and learning outcome tests. The results of the study showed an increase in student learning outcomes and activities in each cycle. In cycle I, the average score was 73.61 with 63.89% completeness and 83.33 activity scores. In cycle II, the average score increased to 86.67 with 88.89% completeness and 91.67 activity scores. These results indicate that the Discovery Learning model effectively enhances student engagement and achievement, making it a feasible alternative teaching strategy in chemistry learning at the senior high school level.
