Abstract

One effort to improve understanding of concepts and problem-solving skills in learning physics is to provide instructional materials in accordance with the characteristics of the students and help students learn. The purpose of this study are: (1) developing a high school physics teaching materials especially materials Rotation Dynamics and Equilibrium Rigid objects using multiple representations approach to improve the understanding of physics concepts, (2) test the effectiveness of instructional materials development results. This research method is the development of research using Dick & Carey model tailored to the needs of research. The research instrument used in the form of feasibility questionnaire. The type of data that is obtained is quantitative data and qualitative data. Experimental results show that the result of the development of teaching materials can be categorized as very feasible. Results of field trials showed that: (1) most of the students in the experimental class above KKM obtain test results, (2) the results of the experimental class postes greater than the control class, so that teaching materials said to be effective, but not significant to improve the understanding of physics concepts.
