The selection of subjects uses purposive sampling with the instrument of problem solving ability based on Polya and AQ questionnaire. Data validity uses data triangulation methods. This research uses data analysis in the form of data collection, data reduction, data presentation and drawing conclusions. The result of this research indicate students with the type of quitters are able to carry out the step to understand the problem. Students with AQ type campers are able to carry out the steps of understanding the problem, planning solution and carrying out a plan of resolution. Climbers type students are able to carry out step to understand the problem, plan the completion, carry out the settlement and check again.
