Developing instructional design of statistics material based on realistic mathematics education (RME) to improve mathematical communication ability and learning independence for junior high school grade VIII students Available to Purchase

Students' learning independence is still lacking, which is the reasons for conducting this research. The purpose of this study is to determine the effectiveness of the development of learning design through statistical concepts using the Realistic Mathematical Education (RME) approach to mathematical communication skills implemented in Hypothetical Learning Trajectory (HLT), teacher books and student books are valid and practical. The method used in this study is the combination of the Plomp design research model and the Gravemeijer & Cobb model. The research subjects were students of class VIII MTs. The data collection technique used posttest test from small group students. The results of the posttest test of students reached a value above the KKM (75) with an average of 87.96 and the average student learning independence during the learning process reached 76.07 with a good category. Therefore, the development of learning design based on RME approach is effective for students' mathematical communication skills in statistical material and can increase students' learning independence.
