Abstract:
Research on the application of learning strategies beach ball has been carried out
to determine the increase in student achievement on the subject of the colloidal
system in class XI Science SMAN 10 Pekanbaru. form of research is experimental
research with pretest-posttest design. time data collection begins from the date of
May 14 to 29 2013. sample consisted of two classes, namely class XI science 3 as
the experimental class and the class XI science 5 as control class is randomly
selected after the homogeneity test. experimental class is a class that is treated by
applying learning strategies beach ball, while the control class is treated to a
lecture and discussion methods usual. data analysis techniques is used by t-test.
based on final data processing results using t-test formula obtained t
hitung
> ttable
(3.06> 1.994) it means the application of learning strategies beach ball to improve
student achievement on the subject of colloidal systems in class XI Science
SMAN 10 Pekanbaru. Size of category increase student achievement on
experiments class is supported with the normalized gain scores (N-gain) of 0.777
is high category.
