Abstract

This study aims to determine the effectiveness of the Problem Based Learning (PBL) model on the mathematical problem-solving ability of high school students on the topic of quadratic functions. The research method used was a quasi-experimental design with a pretest-posttest control group design. The research population consisted of eleventh-grade high school students, with a sample of 60 students divided into two groups: an experimental group of 30 students (PBL) and a control group of 30 students (conventional learning). The research instrument was a validated mathematical problem-solving ability test based on Polya's indicators. Data were analyzed using an independent sample t-test and Cohen's d effect size. The results showed a significant difference in mathematical problem-solving ability between the experimental and control groups (p
