Abstract
Creative thinking ability is one of the capabilities needed to face up various situations and problems in life, So students should have this ability. The purpose of this study is to determine the effectiveness of the use of problem-based learning method in improving students creative thinking ability. The method used is a mixed method with the explanatory sequential design. This method begins with the use of quantitative methods by performing pretest and posttest to find out the average gains normalized their creative ability, then continued the interview to find out more about their experience in using problem-based learning and its effectiveness in improving the ability of creative thinking. The result of the research shows that there is an increase of students creative thinking ability by using problem-based learning model, with pretest rate (19,9) and posttest (71,4) normalized gain score 0,856, the increase is in the high category. Interview results also show that problem-based learning is effective and can accommodate creative thinking ability, also provides flexibility to improve other cognitive abilities
