PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING UNTUK MENINGKATKAN HASIL BELAJAR MATEMATIKA PADA MATERI BANGUN DATAR SISWA KELAS III SEKOLAH DASAR

Abstract

This study aims to improve the mathematics learning outcomes of third-grade students at SD N 2 Bebandem on plane geometry by implementing the Problem Based Learning (PBL) model. The research method used was Classroom Action Research (CAR), implemented in two cycles, with the stages of planning, action, observation, and reflection. The subjects were 19 third-grade students at SD Negeri 2 Bebandem. Data collection techniques included observation, testing, and documentation, while data analysis was conducted using descriptive quantitative methods. The results showed an improvement in student learning outcomes in each cycle. The average student score increased from 62 in the pre-cycle to 71 in the first cycle, and again to 83 in the second cycle. The learning completion percentage also increased from 37% in the pre-cycle to 58% in the first cycle, and reached 84% in the second cycle. These results indicate that the implementation of the Problem Based Learning model is effective in improving students' mathematics learning outcomes on plane geometry. Furthermore, this model is also able to increase students' activeness, collaboration, and critical thinking skills during the learning process.
