Abstract:
This research aims to increase mathematics learning outcomes of
students by implementing cooperative learning model of numbered heads type
approach in class X
2
SMA Negeri 2 Tanjungpinang even semester of academic
year 2011/2012 . This study uses action research of class. It was conducted in two
cycles. The subjects studied were students of class X2
SMA Negeri 2
Tanjungpinang with the number of 32 people comprising from 17 male students

cycle of two, a teams awarded good team and seven other awarded great team,
while in the second cycle, six teams awarded great team and two teams awarded
the super team. The conclusion of the study showed that the implementing
cooperative learning model of numbered heads type approach could improving
mathematics learning outcomes of students.
