Abstract

This research aimed to know the effectiveness of problem based learning towards students mathematical communication skill. The population of this research was students of grade VII in SMP Negeri 3 Metro in academic year of 2017/2018 that were distributed into 7 classes. The samples of this research was students of class VII-D and VII-E which were chosen by purposive sampling technique. The design of this research was pretest-posttest control group design. Research data were obtained through test of mathematical communication skill. The statistical test used was t-test and z-test. Based on the result of the research, it was concluded that problem based learning was not effective towards students mathematical communication skill. Penelitian ini bertujuan untuk mengetahui efektivitas problem based learning terhadap kemampuan komunikasi matematis siswa.
