Abstract:
The research on the application Problem Solving model is conducted at XI IPA
class of SMA Muhammadiyah 1 Pekanbaru which is apllied on colloidal topic in
2013. The research is an experiment with pretest-posttest design. The sample
consisted of two classes, named class XI IPA3 as the experiment class and the

solving model, while the control class was treated to as convensional. Data
analysis technique used the t-test. The result of research showed tarithmetic
>ttable
(4.97 > 1.67) and n-gain is 0,71. It is high category. It means the application
Problem Solving model can to increase learning achievement on colloidal topic at
