This research aims to determine the effect of Problem Based Learning using puzzle media on students' critical thinking. The study population was all grade VII students at SMP Muhammadiyah 3 Bandar Lampung totaling 192 people. The research sample was students from 2 classes, namely class VII D and VII F who were selected from the population by using purposive sampling technique. The research instrument used a pretest-posttest sheet. The design used is the nonequivalent control group design. The data analysis used t-test with a significance of 5%. The results showed a sig significance value. (2-tailed) 0.13 <0.05, which means that the n-Gain mean of critical thinking learning outcomes of students between the experimental class and the control class is significantly different. Thus, it is known that the problem-based learning model using puzzle media can affect the critical thinking skills of students.
