This research aimed to describe the effectiveness of problem solving learning model to improve student’s flexibility thinking skills in acid-base subject matter. The population of this research was the students of class XI IPA SMA Al- Azhar 3 Bandar Lampung on academic year 2013/2014. The sample was taken by purposive sampling technique and obtained class XI IPA 4 and XI IPA 5 as sample classes. This research used quasi experimental method with non equivalent pretest-posttest control group design. The effectiveness of problem solving learning model was showed by the significant difference of n-Gain between control and experiment class. The result showed that the average n-Gain of flexibility thinking skill of control class and experiment ...
