Turnitin: The Development of Learning Instruments through the Problem-Based Learning Model to Enhance Students' Creativity

Lack of opportunities for students to express ideas during the learning process makes students having difficulty in solving their daily life problems. Realizing the importance of mathematical creative thinking ability, it required the development of learning tool through Problem Based Learning (PBL) model. This study aimed to develop the valid learning tools through the PBL model to improve the creativity of students. Learning tools were developed based on the 4D model, that refers to define, design, develop, and disseminate. However, this research only focussed on the first three stages. The results showed that learning tools through the PBL model in improving student creativity meet the criteria of validity, in which the score was 4.13 (highly valid). Furthermore, the learning tools developed through the PBL model in this study can be used for further analysis, including in practicality and effectiveness phases.
