Abstract

Abstract. This study aims to produce mathematics teaching materials that satisfy the criteria of validity and through a process of validations teaching materials. Mathematics teaching materials developed by project-based learning integrated STEM can be said to be quite new so that the validation process is an important thing that teaching materials must be passed to measure its feasibility. This research is part of the research and developement (R & D) where this developement stage yields the percentage of the prevalence of teaching materials. Researchs data obtained from the process of face validation, construct validation, and content validation by the experts of material test, experts of media, and small scope trials in 36 student of junior high school. The results of the validation process of the test subjects can be concluded that the materials being developed are feasible and valid for use in broad scope trials or furthermore feasible to be used in the learning process.
