Critical thinking skills are essential for students in the 21st century. Through this skill, a person can solve problems systematically to reach rational and logical conclusions. Critical thinking skills can be improved by using appropriate media and learning models in the classroom. This research focuses on the influence of using Game-Based Learning (GBL) media taught using the Problem-Based Learning (PBL) model on students' critical thinking skills in science learning with the topic of earth structure. This research is quantitative research using a pre-experimental design through a one-group pretest-posttest design. The sampling technique was carried out using cluster random sampling, and a research sample of 32-grade seventh students at SMP Negeri 1 Sampit was obtained in the even semester of the 2023/2024 academic year. Data collection techniques are carried out using tests. The data analysis technique used is a paired sample t-test. The research results show that science learning using GBL media with the PBL model can improve students' critical thinking skills with a two-sided p-significance value of <0.001 and a Cohen's d effect size of 0.972, included in the large category. All indicators of critical thinking skills have increased, with the highest increase occurring in the analyzing indicator and the lowest increase in the evaluating indicator. Based on these results, learning using GBL media and the PBL model can be a recommended science learning strategy. © 2024 IEEE.
