Developing the Geometry Teaching Module by Using a Metacognitive Approach in Kurikulum Merdeka to Improve the Students’ Critical Thinking Skills

This research aims to solve the problem of students’ critical thinking skills to follow instructions in solving mathematical problems. Students are often unaware of what they do, why they do it, and do not even know what they are supposed to do with the assignment. Meanwhile, to be a good problem solver, someone must develop good metacognition skills. By having metacognitive awareness, students are trained to solve mathematical problems through the stages of planning, monitoring, controlling and evaluating. The method used in the research is Research and Development with the model developed by Thiagarajan, Semmel & Semmel (4-D). The data collection was based on the pre-test and post-test scores in the experimental and control groups to measure the students’ critical thinking skills. The result of the post-test in the students’ critical thinking skills by using ANOVA test with significance level in 0.016 (< 0.05) shows that there was significant difference of teaching module with metacognitive approach in the material about circle within Kurikulum Merdeka to the students’ critical thinking skills.
