Improving Mathematics Learning Outcomes on the Area of Plane Figures Among Fifth Grade Students at SD Negeri 2 Kasri Through the Implementation of the Discovery Learning Method

Abstract

This Classroom Action Research aims to improve mathematics learning outcomes on the topic of Area of Plane Figures through the implementation of the Discovery Learning method among fifth-grade students at SD Negeri 2 Kasri. The background of this study is the low learning outcomes, where only 3 out of 17 students (18%) scored above the Minimum Competency Assessment (≥75) prior to the intervention. The main cause of this low achievement was the use of conventional teaching methods that did not actively engage students. The research was conducted in two cycles, following the steps of the Discovery Learning method: stimulation, problem identification, data collection, data processing, verification, and drawing conclusions. The results showed a significant improvement in student achievement. The number of students scoring ≥75 increased to 8 in Cycle I and 15 in Cycle II. Thus, the application of the Discovery Learning method proved effective in enhancing students’ understanding and learning outcomes on the given topic.
