Improving Science Learning Outcomes on Vibration and Wave Materials Through Discovery Learning for SMP Negeri 1 Tegalrejo

Abstract

Science learning outcomes, especially vibration and wave material, are not optimal. The enthusiasm of students in participating in learning is less than optimal, which is indicated by the number of students who are less focused, less disciplined, and less active. To improve the science learning outcomes of vibration and wave material, research was conducted using the Discovery Learning model in class VIII D SMP Negeri 1 Tegalrejo, totaling 30 students. This research is a type of classroom action research conducted with two cycles. The method of data analysis of the research results used is descriptive quantitative and descriptive qualitative. From the initial test results of the cycle there were 9 students who completed learning individually with a percentage of learning completeness of 30%. In the first cycle test results, 20 students were declared individually complete with a percentage of learning completeness of 73.33%, while in cycle II the number of students who were individually complete was 26 students with a percentage of learning completeness of 86.67%. Based on the results of the study, it can be concluded that learning using the Discovery Learning model can improve the learning outcomes of IPA vibration and wave material in students of class VIII D SMP Negeri 1 Tegalrejo.
