Abstract
The rapid advancement of technology and science education demands innovative approaches to develop students' critical and creative thinking skills. However, there is limited systematic evidence about the effectiveness of different physics teaching materials in fostering these essential 21st-century skills. This study aims to investigate the effect of physics teaching materials on critical thinking skills and creative thinking skills of high school students through a comprehensive meta-analysis of recent research. Using purposive sampling, 20 articles from national journals published between 2019-2023 were analyzed. The results revealed three key findings: (1) physics teaching materials showed varying degrees of effectiveness across different formats, with modules and student worksheets demonstrating the highest effect sizes (3.93 and 3.97 respectively); (2) physics teaching materials significantly enhanced students' critical thinking skills with a high effect size category (3.97); and (3) these materials effectively improved creative thinking skills with a high effect size category (2.97). These findings provide valuable insights for educators and curriculum developers in designing and implementing effective physics teaching materials
