Abstract:
This research aims to improve students' mathematics learning outcomes by implementing cooperative learning model of Student Teams Achievement Divisions (STAD) type in class IVA SDN 009 Langkan, Langgam Sub District, District of Pelalawan, in the even semester of the academic year 2011/2012. This study uses action research. The subjects studied were students of class IVA SDN 009 Langkan with the number of 30 people consisting of 16 male students and 14 female students.

The conclusion of this study indicate that cooperative learning model model type Student Teams Achievement Divisions (STAD) can improve students' mathematics learning outcomes.
