This research is based on the development of 21st century learning, where PowerPoint is one of the applications that support learning with attractive designs. This research is a type of R&D development research with the ADDIE model as the development model. The research population was class II students, with a sample of 10 students from SDN Gempolkerep. The data analysis technique used is the Likert Scale. Flat shape material is introduced at the low grade level, and in this product, the material is associated with local culture, especially the culture in Mojokerto, East Java, which is adjacent to this research area. The results showed that the interactive Flat Math media had been tested for its feasibility and declared fit for use. The validation results of media experts get a percentage of 75% which indicates eligibility, while the results of the validation of material experts get a percentage of 86% which indicates very feasible qualifications. Linguist validation also shows decent results with a percentage of 76%. The average questionnaire results from student respondents show a percentage of 80.4% which indicates that this media is very feasible to use. In addition, the teacher's assessment also gave a percentage of 82%. Based on the data analysis, it can be concluded that Flat Math interactive media is appropriate for use in supporting learning in flat shape material.

Students feel physics is a difficult subject and full of formulas, the amount of subject matter that must be memorized, lack of motivation from within students to learn physics, and the inaccuracy of models, methods, and learning media used by teachers, so that learning activities feel bored and boring. Theaim of the research to determine student learning outcomes using the Discovery Learning model assisted by Powerpoint media. This type of research is quantitative research. From the data analysis, the average score of the experimental class was 10.32 with a classification standard of 2.19 and the average score of the control class was 10.06 with a division standard of 2.08. In the normality test for the experimental class obtained Lcount< Ltable = 0.066 < 0.246 and in the control class Lcalculate< Ltable = 0.056<0.234 then both classes have normal distributed data. In the homogeneity test of the data of both samples obtained Fhityoung ≤ Ftabel = 0.429 < 0.657 then both samples came from samples that Homogeneous. The results of the t test are obtained tcount>t table = 2.021 > 1.684 so that Ha is accepted. Thus, this study shows that there is a significant influence on the discovery learning learning model using PowerPoint media on student learning outcomes at SMAN 1 Tanoh Alas.
