Abstract:
The Research is about using cooperative learning of model Bermain
Jawaban which has been done to improve student’s achievement on the topic of
reduction and oxidation reactions at 10
th
of SMA Babussalam Pekanbaru in March
2013. This research is experimental research based on pretest-posttest design. The
sample consisted of two classes, X.1 class as control class and X.3 class as
experiment class that randomly selected after testing homogeneity. Cooperative
learning of model Bermain Jawaban is applied in X.3. Analysis of data used t-test.
Results of data processing obtained tcount > ttable (2.67 > 1.67). It means that using
cooperative learning of model Bermain Jawaban can improve student’s
achievement on the topic of reduction and oxidation reactions at 10
th
of SMA
Babussalam Pekanbaru. The improvement of student’s achievement in experiment
class was supported by N-Gain score as many as 0,74 that included in high
category.
