Abstract: This study aims to develop science teaching materials with discovery learning-based visual media and discuss improving student learning outcomes using science teaching materials with discovery learning-based visual media on human circulatory system material. This research refers to the procedure of conducting research "Research and Development" follow the stages of floating research according to the Directorate General of Higher Education by combining the stages of Dick and Carrey. The test subjects consist of theoretical trials and empirical trials. The theoretical trials consist of learning material experts and instructional media experts in the field of Natural Sciences. The empirical trial consists of 10 students in small groups and 16 students in large groups. The instruments used were interviews, questionnaires, and learning achievement tests. The results of the validation of expert learning materials and media products were included in the excellent category with a value of 90.76% The data obtained were analyzed by using an Paired Sample t Test was found to be Sig (2-talied) <0.05, meaning that the development of teaching materials with visual media based on discovery learning was already good and feasible to be used in the implementation of learning and development of teaching materials with teaching media based on visual media Discovery learning is very good to use because it can significantly improve student learning outcomes in the material of the circulatory system in humans in class VIII.A in Wori Christian Middle School.
