PERBEDAAN KEMAMPUAN KOMUNIKASI MATEMATIS SISWA MENGGUNAKAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) DENGAN MODEL PEMBELAJARAN KOOPERATIF TIPE STAD DI KELAS VIII SMP NEGERI 1 SELESAI T.A 2015/2016

Abstract

study aims to look at the differences in students' mathematical communication skills by applying two models of learning, ie learning model Problem Based Learning (PBL) and cooperative learning model STAD on the  Pythagorean theorem material. Research conducted  at SMP Negeri 1 Selesai with the sampling technique is simple random  sampling  and  selecting classes done at random, obtained class VIII-3 as the experimental class A and class VIII-7 as the experimental class B respectively numbered 34 and 32 students , The instrument used in this study is a test essay by the number of items have been about 6 divalidkan by the validator. Data analysis using t test at significance level of 5% with the prerequisite test of normality and homogeneity. In both classes the pretest data testing showed  that  both classes  of data were normally distributed and homogeneous. T-test-pretest posttest difference of data obtained t = 7.78255, while table = 1.669. Because t_count> t_table (7.8255> 1.669), then Ho is rejected and Ha accepted, which means that there are differences in students' mathematical communication skills taught by learning model Problem Based Learning and the model type STAD cooperative learning in class VIII SMP Negeri 1 Selesai.
