Abstract

This quasi experimental research aimed to know the effectiveness of problem based learning in the terms of student’s understanding of mathematical concepts. This research used pretest-posttest control design with population was all students of grade seven of SMPN 2 Way Seputih in academic year of 2014/2015 and samples were students of VIIA and VIIC class that were chosen by purposive random sampling. The data of research were obtained by essay test. Based on the result of research, it could be concluded that problem based learning model was not effective in the terms of students understanding of mathematical concept, but more effective than conventional learning model.Penelitian eksperimen semu ini bertujuan untuk mengetahui efektivitas model problem based learning ditinjau dari pemahaman konsep matematis siswa.
