Abstract


Learning process still emphasizes on knowledge aspect and materials comprehension, students’ active participation is very low, and students’ learning competencies are still low too.  One way to solve those problems is by doing research using Problem Based Learning model. The purpose of the research was to know the effect of Problem Based Learning model towards students’ critical thinking and students’ learning competencies. It was a quasi experimental research. The population of the research was students of VIII grade in SMPN 21 Padang in academic year 2017/2018. The samples were taken by using random sampling technique. As a result, class VIII3 was as experimental class and class VIII4 was as control class. The instruments used were objective test, critical thinking ability test, observation sheet to see affective aspect and assessment sheet to see psychomotor aspect. The analysis of data used T-test for cognitive competence and Mann Whitney U test for affective and psychomotor competences. The result showed that students’ critical thinking ability and score in learning IPA of experimental class is better than students’ critical thinking ability and  score in learning IPA of control class
