Application of Project Based Learning Methods to Improve Mathematical Problem Solving Abilities in Senior High Schools

Abstract

This research aims to evaluate the effectiveness of project-based learning methods in improving students' mathematical problem solving abilities in high school. This method engages students in learning activities that focus on real projects, allowing them to develop critical and creative thinking skills and apply mathematical concepts in real-world contexts. The research was carried out using a quasi-experimental design, where one class was used as an experimental group using project-based learning methods, and another class was used as a control group using conventional learning methods. Data was collected through tests of mathematical problem solving abilities before and after treatment, as well as questionnaires to measure student responses to the learning methods used. The research results showed that students who studied using project-based learning methods experienced a significant increase in mathematical problem solving abilities compared to students who studied using conventional methods. Apart from that, students also show a more positive attitude towards learning mathematics. These findings indicate that project-based learning methods can be an effective alternative for improving the quality of mathematics learning in high schools.
