The aim of this study is to enhance students' creative problem-solving ability using a project-based learning approach. The study was based on a quasi-experimental design and the participants were 69 postgraduate students in the field of education management. There were 35 of the students assigned to the experimental group, and the remaining 34 to the control group. The experiment was conducted over 15 classes for 2 months. A creative problem-solving questionnaire was used as a pre-test and post-test before and after the experiment. The results showed that the students' creative problem-solving ability had been effectively enhanced by the intervention of project-based learning, especially in terms of identifying problems, finding solutions and evaluating them.
