Development of STEAM-Based Mathematics Teaching Materials on Direct and Inverse Proportion to Improve Mathematical Problem-Solving Ability and Self Regulated Learning

This research was and development whose product in the form of teaching materials based on STEAM (Science, Technology, Engineering, Art, Mathematics). aims to analyze feasibility readability, as well test effectiveness improving problem-solving abilities Self Regulated Learning (SRL). The stages include potentials problems; data collection; design; design validation revision; trials (readability tests) revisions; trial implementation then final product. Furthermore, this study used a one-group pretest posttest design, carried out at MTs Al-Utsmani with 37 class VIID students 2022/2023 academic year respondents. results indicate that developed STEAM-based have level 92.82% very feasible criteria; legibility 63.22% easy-to-understand effectively improve SRL. is indicated by average mathematical after using more than or equal Minimum Completeness Criteria, ability who achieve Criteria complete classical manner proportion least 75%, Improvement students' moderate minimal category, SRL are categories, category while improvement category.
