Abstract


Kaseba (Multi-sided Bag) learning media is a media that can be used to improve student learning outcomes in Mathematics subjects on flat shapes. The purpose of this development research is to determine the validity, practicality, and effectiveness of Kaseba (Multi-sided Bag) learning media to improve learning outcomes on flat shapes in grade IV students of SD Negeri Bendungan 1 in 2025. The research method used in this research and development is R&D (Research and Development). The media developed through the validation stage of media experts and material experts. It can be seen that the media is suitable for use, because it obtained a score of 87,5% with very valid criteria. The results of the practicality of the teacher response questionnaire with a score of 94% with very practical criteria. The results of the practicality of the student response questionnaire got a score of 90% with very practical criteria. So that the Kaseba learning media can be said to be practical. The pretest score obtained an average of 55.93 and the posttest score obtained an average of 91.43. So that the N-Gain value was obtained of 0.8111 with high criteria. So Kaseba learning media can be said to be effective.
