The purpose of this research is to examine the effectiveness of student worksheet (LKPD) based on realistic mathematics educations (RME) of class VIII of Junior High School. This is a development research with Plomp Model. The research design employs quasi experiments with Only-Posttest Control Group Design. This research took place in Public Junior High School (SMPN) Padang of class VIII. The sample is determined by purposive sampling. The treatment toward experiment group is learning by using LKPD based on RME. Meanwhile, control group is using student book according to curriculum 2013. The research instruments are test items, learning observation sheet, and learning device which had been tested for validity and practicality in the development research stage. Data analysis is conducted through t test for the mean difference test and the Scheffe test for the effectiveness of the LKPD test. The research result showed that students' mathematical communication ability of class VIII of Junior High School (SMP) by using LKPD based on RME is better than student who uses student book. Finally, it can be concluded that LKPD based on RME is effective in improving students' mathematical communication ability. © 2020 Published under licence by IOP Publishing Ltd.
