Abstract:
This research aims to improve student’s mathematics learning
outcomes by implementing cooperative learning model of Students Teams
Achievement Division (STAD) type in class IV SD Negeri 002 Sipungguk, in
even/second semester of academic years 2012/2013. This study uses the
classroom action research. The subject studied were students of class IV SD
