Penerapan Discovery Learning dan PSE untuk Meningkatkan Pemahaman Konsep Bangun Datar dengan Puzbang

Abstract

This research is motivated by the low understanding of the concept of plane figures in grade 4B students of SDN Bandungrejosari 1, Malang City, which is characterized by the inability to distinguish similar geometric shapes and the lack of active participation in the learning process. This study aims to improve mathematics learning outcomes through the application of the Discovery Learning model combined with the Social Emotional Learning Approach (PSE) and concrete media in the form of PUZBANG (Flat Building Puzzle). This research is a Classroom Action Research (CAR) with a quantitative descriptive approach implemented in two cycles. Data were collected through observation, documentation, and learning outcome tests. The results showed a significant increase in student understanding. In the pre-cycle stage, only 35.7% of students passed the KKM (≥75), increasing to 53% in Cycle I, and reaching 89% in Cycle II. In addition, there was an increase in social interaction, self-confidence, and active involvement of students in group discussions. These findings indicate that the combination of the Discovery Learning model, the PSE approach, and PUZBANG media can effectively improve learning outcomes while building students' social emotional skills. Therefore, this learning strategy is worthy of broader application in the context of elementary school mathematics learning.
