The low critical thinking skills of students are attributed to suboptimal instruction that fails to adequately center on the students during the learning process. This research was conducted to investigate the effect of Case Method based Student Worksheets (LKPD) in enhancing students' critical thinking skills. The instruments utilized included the Case Method LKPD, which had been declared valid by experts, and a student critical thinking skills test. The Case Method based LKPD has fulfilled the effectiveness criteria, wherein: (a) there was an increase in the average score of students' critical thinking skills by 21.51; (b) it was statistically proven that there is a significant difference in the critical thinking skill scores of students in the control and experimental classes utilizing the Mann Whitney test (U = 28.500, p = 0.00); and (c) a total of 10 students experienced an enhancement in critical thinking skills with a gain score of 0.7 ≤ g within the high category, while 25 students experienced an enhancement in critical thinking skills within the range of 0.3 ≤ g < 0.7 within the moderate category.
