EFEKTIVITAS MODEL PEMBELAJARAN KOOPERATIF TIPE TSTS DITINJAU DARI PEMAHAMAN KONSEP MATEMATIS SISWA

Abstract

This quasi experimental research aims to know the effectiveness cooperative learning type two stay two stray considered by student's mathematical conceptual understanding. The research design uses posttest only control group design. The population of this research is seventh grade students of junior high school state 26 Bandar Lampung in academic years 2012/2013 and the samples of reseach are VII A and VII D that is choosen from six classes by using purposive sampling technique. Based on data analysis, it is gotten the average of congnitive value of student’s mathematical conceptual understanding in class with cooperative learning type TSTS is higher than in class with conventional learning and also 70% or more students in class using cooperative learning type TSTS have completed in learning mathematics. The conclusion of this research is cooperative learning type TSTS effective considered by student's mathematical conceptual understanding.
