Abstract
This study aims to develop teaching materials based on Community Science Technology (STM) for natural science subjects on changes in the shape of objects. The research method used is a type of research and development (R&D), using the ADDIE model, namely analysis, design, development, implementation, and evaluation. The data collected in this study are related to validity, practicality and effectiveness data. Data obtained from the validation results of material experts showed an average score of 82.3% in the very feasible category, and media experts obtained an average score of 83.5% in the very feasible category. The results of practicality based on the teacher's response obtained an average score of 82% in the practical category and student responses obtained an average score of 80% with practicality. The next data relates to the effectiveness of the product which scored 91% with very effective criteria. From the results of the research conducted, it was concluded that teaching materials based on community science and technology (STM) were stated to be very valid, very practical, and very effective so that they could be used in natural science learning material for changes in the shape of objects.
