Abstract

This research development aims to develop learning tools realistic mathematics education valid, practical and effective and analyze the improvenment of communication skills in the application of realistic mathematics education learning tools. This study uses 4-D model. The result showed that, validity of RPP product total score of 4.1 was in the “valid” category. Teacher book and student book total score of 4.2 is was in the “valid” category. The LKS total score of 4.1 was in the “valid” category. Practically of learning tools based on the implementation of learning reaches an average of 3.5 with a high category. The effectiveness of learning tools based on student‟s learning reached 85% with complete criteria and improvement of student‟s mathematical communication skills, which increased from 35% to 72%
