Development of Physics Teaching Materials Based on Mind Maps with Multimedia Concepts to Improve Student Learning Outcomes. This study aims to 1) Develop teaching materials based on mind maps with multimedia that are feasible to use. 2) Learning materials with a concept (mind map) with multimedia can improve student learning outcomes. The research method used is the research and development method (Research and Development). The subject of the research trial consisted of theoretical trials and empirical trials. The theoretical trial consists of 2 people divided into 1 person as an expert on design & learning and 1 person as a theorist in the field of physics. For the empirical test consisted of 10 people for the small group test, 20 people for the field trial and 30 people for the operational test. The instruments used in this study were questionnaires and test results. Data on student learning test results from 2 groups were analyzed by the experimental method pretest-posttest control group design. The data were analyzed descriptively and the mean difference test. In accordance with the testing criteria, namely if the significance value or sign (2 tailed)> 0.05 then H0 is accepted and H1 is rejected and if the significance value or sign (2 tailed) <0.05 then H0 is rejected and Ha is accepted. Then based on processing data obtained a significance value of 0.009 <0.05. So that it can be concluded that, the average learning outcomes using multimedia-based mindmap teaching materials is higher than conventional teaching and learning materials.
