Abstract

The 2015 TIMSS and 2018 PISA results show that Indonesia's science performance remains below the international average and declined further in 2022. This indicates students weak critical thinking skills (CTS) in understanding scientific concepts. An effective and interactive learning model is needed. This study aims to compare students' CTS using the traditional game in problem-based learning (TG-PBL) model and the problem-based learning (PBL) model. The research used a quasi-experimental design with a pretest-posttest non-equivalent control group and purposive sampling. Statistical tests included the paired sample t-test, independent sample t-test, and N-gain score. The independent t-test showed a significant difference between TG-PBL and PBL classes (0.000). The paired t-test showed a difference between pretest and posttest in both classes (0.000), with a greater increase in the TG-PBL class. The N-gain in the TG-PBL class was 0.57 (medium category), while in the PBL class it was 0.24 (low category). The highest improvement in the TG-PBL class was in the basic support indicator (0.630), while in the PBL class it was in strategies and tactics (0.398). The TG-PBL model is more effective in improving students CTS. It creates a more interactive, relevant, and innovative science learning environment in junior high schools

Abstract

Critical thinking skills (CTS) are essential in the 4.0 era. However, the attempts to enhance these skills during learning are still suboptimal, particularly in science education at the junior high school. Gender is believed as one affecting factor on students critical thinking. The research investigated the effects of problem based learning (PBL) student worksheets on students critical thinking from the perspective of gender differences. This quasy experimental research applied pretest-posttest nonequivalent multiple group design. The samples were chosen through purposive sampling, resulting in one male class having 24 students and one female class having 24 students. The research instruments included a lesson plan, a PBL-based student worksheet, and pretest-posttest questions that had been validated. Data analysis uses statistical tests in the form of paired and independent sample t-tests, and N-gain. The analysis indicated that using PBL-based student worksheets increases CTS more effectively in female students than in male students. These are proven by paired and independent sample t-tests showing a significant difference (Sig. 2-tailed = 0.000 0.050) with N-gain signifies a moderate increase of 0.6 for male students and a high increase of 0.7 for female students. These findings may serve as recommendations to enhance students critical thinking and as a reference for gender-segregated schools in designing learning programs that optimize the role of each gender
