Improving the Mathematics Learning Process and Students' Problem-Solving Skills through Problem-Based Learning
Abstract
This study aims to improve the learning process and improve students' mathematical problem-solving abilities by implementing the problem-based learning model. The subjects of this study were students of class VIII.1 of SMP YLPI P. Marpoyan in the first semester of the 2024/2025 academic year. This study consisted of two cycles, the first cycle containing two meetings with the material One Variable Linear Equations, and the second cycle containing two meetings with the material One Variable Linear Inequalities. Data analysis was carried out using a combination of qualitative descriptive analysis and quantitative descriptive statistical analysis. The data analysis technique used in this study consists of analyzing data on teacher and learner activities and analyzing data on students' mathematical problem-solving abilities. The results showed that the application of the problem-based learning model improved the learning process and improved students' mathematical problem-solving abilities. The average N-gain score increased from 0,58 with a medium classification in cycle I to 0,88 with a high classification in cycle II. In addition, the average student test increased from 54,38 in cycle I to 76,88 in cycle II. The results showed that the application of the problem-based learning model improved the learning process and improved the mathematical problem-solving abilities of class VIII.1 SMP YLPI P. Marpoyan.
