Abstract
This study aims to determine the effectiveness of the application of problem-based learning models (PBL) in improving students' critical thinking skills in the material of Newton's Laws. This study used a quasi-experimental method with a pretest-posttest one group design. The subjects of the study were 30 students of class XI-G of SMA Negeri 1 Nglames, Madiun Regency, in the 2024/2025 academic year. The instruments used included a critical thinking skills test in the form of descriptive questions and an observation sheet for learning activities. Data were analyzed using validity and reliability tests, Shapiro-Wilk normality tests, paired sample t-tests, and N-Gain tests. The results showed that the pretest and posttest data were normally distributed with significance values of 0.465 and 0.092, respectively. The results of the paired sample t-test showed a t-count value of 8.927 with a significance of 0.000 <0.05, which means there was a significant difference between the pretest and posttest scores. The average pretest score of 59.67 increased to 81.00 in the posttest, representing a 21.33-point increase. The N-Gain test showed a score of 0.59, which is categorized as moderate and effective. These findings indicate that the implementation of problem-based learning has a positive effect on improving students' critical thinking skills. Therefore, it can be concluded that the problem-based learning model is effective in physics learning.
