<![CDATA[Critical thinking is very popular in education, and its learning refers to reasoning, analyzing, problem-solving strategies, and finding solutions. Critical thinking is very important for students, but in reality, students' critical thinking skills are still low. The use of appropriate learning models can improve critical thinking, such as the PBL model, which is relevant to learning in the 21st century. The purpose of this study was to examine the effect of integrated interactive PBL learning media on improving critical thinking skills in the subject of the excretory system. This study used a quasi-experiment with a pretest-posttest control group. The sample consisted of two classes, namely the control class (XI MIPA 3) and the experimental class (XI MIPA 1). Data analysis was performed using the T-test. The T-test results with a significance level (2-tailed) < 0.05 showed that there was an effect of integrated PBL learning media on critical thinking skills. Abstrak.
