Abstract


The aim of study is to identify the effects of Problem Based Learning (PBL) model on the students’ cognitive ability and creativity. The research method used is a quasi-experimental one group pretest and posttest design. It involved 38 students of class XI in SMA at Bandung. The improved learning outcomes are calculated by using the formula N-gain. We use pearson correlation to see the relationship between the improvement of cognitive ability with high category (N-gain average= 74,05%). Achievement of fluency aspect is (84,04%), then for flexibility (87%), originality ( 89%), elaboration (72,05%), and evaluation (51,06%). Increased creative act of student in fluency aspect is (80,74%), then for flexibility (91,56%), originality (83,28%), elaboration (72,76%), and evaluation (89,64 %). There is a strong relationship between improve cognitive ability and creative thinking skills (r=0,602). The relationship of improve cognitive competence and creative act is weak (r= 0,367) and the relationship of creative thingking and creative act is moderate (r= 0,424). Digester biogas is the creative product of student.
