Development of mathematics teaching materials using project-based learning integrated STEM

Developmet of mathematic’s teaching materials using project-based learning model integrated STEM in junior high school not much done yet. Integration of STEM in education becomes a necessary thing to do based on the high demand for human resources who master the STEM field. Project-based learning provides space for students to choose activities to be undertaken during the lesson as well as providing opportunities for implementers of learning to observe activities that are considered more effective in developing student skills. The process of choosing the learning activities undertaken on each student begins with a thought process that results in a decision. This study aims to develop a project-based teaching materials which presents mathematical topics combined with other STEM fields. Based on the analysis of research data, the design of teaching materials often undergoes changes in arrangements of delivery and the amount of content that can be delivered is also accepted by students depending on the diversity of students’ abilities.
