Abstract

This study was motivated by the low level of critical thinking skills among students at SMAN 1 Tanjung Raya. This situation is caused by a learning process that does not fully utilize a learning model appropriate to its stages, resulting in students being passive during the learning process. Therefore, an educational innovation is needed that actively involves students and fosters critical thinking skills through the use of worksheets based on the problem-based learning model. This study aims to analyze the effect of using worksheets based on the problem-based learning model on the critical thinking skills of students at SMAN 1 Tanjung Raya. The research design used is a quasi-experiment with a posttest-only control design. The study population consists of all students in Grade 11 Phase F at SMAN 1 Tanjung Raya for the 2025/2026 academic year. The sampling technique employed is purposive sampling. The sample in this study consisted of the 11th-grade health major class, comprising 31 students as the experimental group, and the 11th-grade engineering major 2 class, comprising 32 students as the control group. Data on critical thinking skills were obtained through a test instrument in the form of essay questions. The analysis techniques used were the normality test, homogeneity test, and hypothesis testing using the independent samples T-test. The results of the study indicate that the average critical thinking skills of students in the experimental class were higher than those of the control class, specifically . The results of the hypothesis test showed that the significance value obtained was 0.00, which is smaller than the significance level of 0.005. Thus, the null hypothesis “ ” was rejected, and the alternative hypothesis “ ” was accepted. It can be concluded that there is an effect of using worksheets based on the problem-based learning model on students’ critical thinking skills in the vector and kinematics material for 11th grade.
