This study aims to produce effectiveness from the development of learning design through statistical concepts using the Reali stic Mathematics Education (RME) approach to mathematical communication skills implemented in HLT (Hypothetical Learning Trajectory), teacher and students book which valid and practical. The method used is a combination of the Plomp design research model and the Gravemei jer & Cobb model, which consists of 3 phases, namely the preliminary research phase (preliminary research / preparing for the experiment), the development phase (development or prototyping phase / design experiment) and the assessment phase ( assessment phase / retrospective analysis). The subjects of this research were students of class VIII junior high school. Data collection techniques that will be used were posttest tests from two classes, namely the experimental class and the control class. Data analysis technique was using the Independent-Sample T Test. The analysis shows that p-value = 0,000 <0.05 means that there are significant differences between the two classes. So, the development of learning design based on Realistic Mathematics Education has a positive impact on students' mathematical communication skills on statistical material. © 2019, IJSTR.
