Powerpoint-based educational games on flat face three dimensional objects combined volume learning

Students are weak in visualization skills, so it is difficult to interpret geometric shapes. Therefore, learning media is needed that can help students learn flat side shapes, one of which is by using PowerPoint as an educational game. This research aims to describe the quality of PowerPoint-based educational games on the combined volume of flat side shapes in the eighth grade of junior high school. The development is carried out using the ADDIE model. The research subjects were 60 grade eight students of SMPIT Al-Uswah Banyuwangi. Data collection was carried out using interviews, observation, questionnaires, tests, and documentation. Data analysis with combined methods (quantitative and qualitative). The results showed that educational games were valid with an average score of 4.39, practical with an average score of 4.67 and the student responses were in a fairly good category with an average value of 3.94 and were not effective according to the analysis of test results which shows . So that the quality of the results of the development of PowerPoint-based educational games on the combined volume material for flat side shapes is not good and needs to be improved. Improvements can be made, especially in terms of sound so that it can be heard more clearly.
