Abstract


This research aims to find out whether the Realistic Mathematic Education approach-based polyhedron teaching materials that were developed achieve the criteria for being suitable for use and to find out whether teaching materials based on the Realistic Mathematic Education approach can improve students' mathematical understanding abilities. This type of research is research and development (R&D) using development procedures which include: Define, Design and Develop. Data collection used instruments for the appropriateness of teaching materials by teachers and lecturers, and instruments for understanding the concept of polyhedron. The results of research on teaching materials according to experts show that the teaching materials developed have very feasible criteria with an average score of 4.48. The test results for the ability to understand mathematical concepts showed an increase with an average score of 0.64.

Keywords
