Abstract: The purpose of this study was to determine the effectiveness of contextual supplements based on students' critical thinking skills. Pre Experiment research design with One Group Pretest-Posttest Design. The study was conducted at Tri Sukses High School class XII. The treatment in the experimental group was learning to use contextual supplements. The instruments used were test items, student activity observation sheets, and observations of learning outcomes. effectiveness is measured based on n-gain test results analyzed with paired sample t-test, student responses to contextual based supplements, and student activity. the results showed that the use of supplements was quite effective in practicing students' thinking skills, as evidenced by the n-gain grade of 0.55 in class XII IPA 1 and 0.65 in class XII IPA 2, as well as the t-test of 0,000 for classes XII IPA 1 and XII IPA 2. by students sebesae 81%, and the percentage of student activity by 83.06%. The results showed that contextual-based supplement was effective for practicing critical thinking skills
