Mathematical communication skills are one of the important abilities possessed by students in learning mathematics. Based on several results of the literature study showed that students' mathematical communication skills are still relatively low. One effort that can be done to improve students' mathematical communication skills is to apply the 7E learning cycle learning model. The purpose of this study is to investigate the improvement in mathematical communication skills of students who use the 7E learning cycle learning model is higher than students who use conventional learning. This type of research is a quasi-experiment using pre-and posttest design. The population in this study were students of class VIII of Junior High School 1 Gantung and the sample of this study was students of grades VIII C and VIII D. The sampling technique used was convenience sampling. The research instrument used to answer the problem formulation was an instrument of mathematical communication ability test in the form of the problem description. The subject in this study is the prism material. The formulation of the problem in this study was answered by inferential statistics using the pooled variance model t-test. The results showed that an average increase in mathematical communication skills was 0.330 for the experimental class and 0.241 for the control class so that the conclusion was that the increase in mathematical communication skills of students who used the 7E learning cycle learning model was higher than that of students using conventional learning.
