Implementation of STEM based PBL with design thinking strategies to improve students creative problem solving capability on renewable energy topics

This research aims to describe the effectiveness of STEM-based PBL with design thinking strategies in improving students' creative problem-solving abilities on renewable energy. This research was conducted at SMAN 1 Sungkai Jaya using a non-equivalent control group design research design. The research instrument used was a description test sheet. Learning by applying the STEM-based PBL model with design thinking strategies can improve creative problem-solving abilities; this can be seen from the average N-gain for the experimental class of 0.49 in the medium category. This is also supported by the data obtained from the Independent Sample t-test, which obtained a Sig value. (2-tailed) is 0.000, and the effect size value is 0.862 in the large category, which can be concluded that the implementation of STEM-based PBL with design thinking strategies can improve students' creative problem-solving abilities on renewable energy topics.
