Analisis Kemampuan Pemecahan Masalah Matematis Siswa Kelas VII Pada Materi Bentuk Aljabar Menggunakan Model Pembelajaran Problem Based Learning di SMP Kristen Palla

Abstract

This study aims to analyze the mathematical problem-solving abilities of seventh-grade students at SMP Kristen Palla on the topic of algebraic expressions using the Problem Based Learning (PBL) model. This research employed a qualitative descriptive approach involving 20 student participants. Data were collected through problem-solving tests and interviews based on Polya's problem-solving steps: understanding the problem, devising a plan, carrying out the plan, and reviewing the result. Data analysis techniques using the Miles & Huberman model, namely; data reduction, data presentation, and drawing conclusions. The results showed that 10 students (50%) demonstrated high problem-solving abilities and achieved mastery, 6 students (30%) were in the medium category, and 4 students (20%) were in the low category. Based on the minimum mastery criterion (KKM) set at 75, 10 students (50%) met the standard, while the other 10 (50%) did not. The PBL model effectively supports students in developing critical thinking and problem-solving skills, making learning more meaningful and contextual. This study is expected to serve as a reference for teachers in implementing effective instructional strategies to enhance students' mathematical problem-solving abilities
