IMPROVING MATHEMATICAL CREATIVE THINKING ABILITY OF JUNIOR HIGH SCHOOL STUDENTS WITH PROBLEM BASED LEARNING MODEL THROUGH STEM
Keywords:
Mathematical creative thinking, Pbl, STEMAbstract
21st century learning intensifies to use creativity in learning. Creativity is essential for all disciplines and learning activities. The STEM integrated PBL model is combined in a teaching material that is prepared with problems that are adapted to mathematical creative thinking indicators. This research aims to study the improvement of creativity in mathematics learning through solving problems in creative ways. The method used is quantitative using t-test, proportion test and N-Gain. The research was conducted at one of the state junior high schools in Semarang Regency. Quantitatively obtained an average pretest value of 72.44 and an average posttest value of 85. 66 and an N-gain test for all indicators of mathematical creative thinking averaged 0.51 with a medium improvement category. The fluency indicator gets a result of 0.38 in the medium category, the flexibility indicator 0.46 on the medium category, the elaboration indicator on 0.48 in the medium category, and the originality indicator gets a result of 0.64 in the medium category. The results showed that STEM learning with the PBL model can improve students' mathematical creative thinking skills through solving problems in teaching materials. The application of stem integrated PBL models can be integrated into interactive media or learning resource materials and integrating STEM learning can be done with direct practical activities.
