Abstract

Mathematics is a discipline that focuses on developing thinking skills. Learning mathematics can hone critical thinking skills, which form the foundation for understanding mathematical concepts and effectively solving problems. This Classroom Action Research (PTK) study was conducted to improve students' critical mathematical thinking skills through a PBL approach. Medical School Negeri 2 Medan was the site of the research. A total of 36 students from the 2023/2024 academic year at SMA Negeri 2 Medan's class XI MIPA 9 served as the study subjects. There were two cycles to this research, and each one included the following steps: preparation, action, observation, and reflection. The data was analyzed using quantitative descriptive analysis, and the methods for data gathering included both tests and non-tests. The results showed that the PBL model has improved the critical mathematical thinking skills of students in class XI MIPA 9 at SMA Negeri 2 Medan. In the first cycle, students' critical mathematical thinking skills reached 75.52% with a high qualification, and in the second cycle, they increased to 87.27% with a very high qualification.

Abstract

The purpose of this study is to determine whether and how the Problem Based Learning approach enhances students' capacity for mathematical creativity. The research was conducted in two cycles using Classroom Action Research (PTK). A total of 36 students from class XI at MIPA 7 SMA Negeri 2 Medan participated in the study. To be considered effective, this research must achieve the following criteria: (1) Students' mathematical creative thinking capacity must rise by 85% or more, falling into the medium group; and (3) Both student and teacher observations must indicate a good level of performance. The study found that while the average score on the first ability test was 58.85, it increased to 67.12 during cycle I and 84.78 during cycle II. Along with an increase in initial ability test scores, there was a rise in classical completeness; in cycle I, that number rose to 24 students (61.11%), and in cycle II, it reached 36 students (100%). The findings suggest that the PBL approach can help students develop their critical thinking skills.
