Improving Second-Grade Students’ Mathematics Learning Outcomes on Picture Diagram Material through Picture-Based Media at Public Elementary School 018 Bukit Sembilan

Abstrak

Mathematics learning is a structured process in which students acquire learning experiences through systematically planned instructional activities. This study was conducted in response to students’ low interest and engagement in the mathematics learning process. The purpose of this research was to improve students’ understanding of picture diagram material in mathematics through the use of picture-based media. The study employed a Classroom Action Research (CAR) design conducted in two cycles at Public Elementary School 018 Bukit Sembilan, focusing on second-grade mathematics instruction using visual media. Data were collected through achievement tests administered at the end of each learning cycle to measure students’ learning outcomes. The results indicated that the use of picture media significantly improved students’ mathematics learning outcomes. At the initial stage, the average student score was 70, with only 5 out of 18 students achieving the minimum mastery criterion (KKM = 75). After the implementation of colorful star picture media in Cycle I, the average score increased to 81, with 12 students meeting the KKM. In Cycle II, the average score further increased to 91, and all 18 students achieved mastery. These findings demonstrate that the use of visual media is effective in improving mathematics learning outcomes and enhancing students’ engagement and interest in the learning process.
