The effectiveness of problem based learning assisted by cabri 3D on student's mathematical communication writing and drawing skills

Abstract

This study aims to describe: (1) the effectiveness of the Problem Based Learning (PBL) model assisted by Cabri 3D on student's mathematical communication writing skills and student's mathematical communication drawing skills; and (2) comparison of effectiveness between PBL models assisted by Cabri 3D and conventional learning on student's mathematical communication writing skills and student's mathematical communication drawing skills. This research is a quasi experiment. The data was collected through tests of student's mathematical communication writing skills and student's mathematical communication drawing skills. The data was analyzed descriptively and statistically. The data is displayed based on average and standard deviation as a descriptively. The statistical test is used to the proportion's test of one population and the proportion's test of two populations. The results of the study is the 5% significance level, it can be concluded that (1) PBL models assisted by Cabri 3D effective on student's mathematical communication writing skills and student's mathematical communication drawing skills; and (2) PBL models assisted by Cabri 3D are more effective than conventional learning models on student's mathematical communication writing skills and student's mathematical communication drawing skills.
