PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE THINK PAIR SHARE TERHADAP PEMAHAMAN KONSEP MATEMATIS

This quasi experimental research aimed to know the influence of cooperative learning model of Think Pair Share (TPS) type towards student’s mathematical conceptual understanding in eight grade students of Junior High School state 4 Way Tuba in academic year 2012/2013. The population was all eight grade students of Junior High School state 4 Way Tuba in academic year 2012/2013. The samples were students of VIIIA class as experiment class and VIIIB class as control class. The samples were chosen by purposive sampling technique. This research used post-test only control group design. Based on result research,it was concluded that the implementation of cooperative learning model of TPS type influences student mathematical conceptual understanding.Penelitian eksperimen semu ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran kooperatif tipe Think Pair Share (TPS) terhadap pemahaman konsep matematis siswa kelas VIII SMP Negeri 4 Way Tuba tahun ajaran 2012/2013. Populasi pada penelitian ini adalah seluruh siswa kelas VIII di SMP Negeri 4 Way Tuba tahun ajaran 2012/2013 yang terdistribusi dalam tiga kelas.
