Abstract:
The purpose of this research to increase student achievement on the subject of
solubility and solubility product in class XI SMA Al Huda Pekanbaru. Form of
research is experiment research with pretest-posttest design. The sample
consisted of two classes. Experiment class was given implementing model
cooperative learning Active Knowledge Sharing, while the control class wasnot
given implementing model cooperative learning Active Knowledge Sharing. The
t-test is used for data analysis technique. Based on the final results of data
processing using t-test formula with dk=53 and ɑ =0,05 obtained tarithmetic>ttable
(2.68>1.67) means that the application of model cooperative learning Active
Knowledge Sharing can improve student achievement on the subject of solubility
and solubility product in class XI SMA Al Huda pekanbaru. Category Increased
student achievement on experiment class including high with the normalized gain
scores (N-gain) about 0,75
