Problem-based learning to improve students' mathematical communication skills and learning motivation

This study aims to analyze the implementation of Problem-Based Learning (PBL) in improving students' mathematical communication skills and learning motivation. The method employed was a Systematic Literature Review (SLR), which analyzed ten published articles from 2019 to 2024. The results indicate that PBL is effective in enhancing students' mathematical communication skills, with 75% of the reviewed articles reporting significant improvements. These improvements were primarily achieved through discussion activities, problem-solving, and collaboration. Furthermore, learning motivation exhibits a positive correlation with mathematical communication ability, as students with higher motivation tend to demonstrate better communication skills. The findings of this study confirm that PBL can serve as an innovative solution to improve students' mathematical communication skills and learning motivation.
