IMPROVING MATHEMATICAL COMMUNICATION ABILITY OF JUNIOR HIGH SCHOOL STUDENTS CLASS VII THROUGH REALISTIC MATHEMATICS EDUCATION
The main purpose of this study to investigate the ability of mathematical communication ofHigh School Students, as a result of learning mathematics through application RealisticMathematics Education (RME). Research design used was a quasi experimental. Subjects inthis study consisted of 70 students of class VII Junior High School, Junior High School on oneof the states in Bandung academic year 2015/2016. Subject determined by purposivesampling techniques, and this study using pretest-posttest design of the control group. Datacollected with a mathematical communication ability test descriptions. Data were analyzedusing parametric statistical tests which is Test Independent Sample T-Test and nonparametrical tests which is Test Mann-Whitney. The results showed that: (1) students wholearn math with RME approach has a better ability mathematical communication of studentswho do not learn math with RME; (2) increasing mathematical communication ability ofstudents who learn with RME better than students who do not learn with RME; (3) students'attitudes toward learning mathematics through RME showed a positive attitude.
