DIFFERENCES IN STUDENTS’ MATHEMATICAL COMMUNICATION ABILITY USING RME APPROACH AND PROBLEM POSING APPROACH AT SMP NEGERI 1 BANDAR

This research aims to find out whether students' mathematical communication ability using the RME approach higher than problem posing approach at SMP Negeri 1 Bandar. This research is a quasi experiment. The population in this research were students of SMP Negeri 1 Bandar. Taking samples was carried out by a simple random sampling technique. Sample in this research were 2 classes, class
VIII-1 as the experimental class I which totals 29 students and class VIII-2 as experimental class 2 which totals 29 students. From the results of research after being treated for 3 meetings, namely in the experimental class I with the RME approach, the pretest average was 20.38, the post-test average was 83.55 and the experimental class II with the problem posing approach obtained the pretest average was
21.86, and the post-test average was 77.59. The results of t-test with dk = 56 and α = 0.05 obtained post-test data was found that tcount > ttable namely 3.158 > 2.00324 which means Ha is accepted. The conclusion is students' mathematical communication ability using the RME approach higher than students’ mathematical communication ability using problem posing approach.
