  • Problem Based Learning is a set of teaching models that use problems as a focus for developing problem solving skill. The purpose of this study is the produce qualified learning materials which is developed based on Problem Based Learning and analyze the improvement of students mathematic problem solving ability which is learned using Problem Based Learning materials. This research is a development research using the Thiagarajan 4-D development model. Trials of learning materials based on Problem Based Learning were conducted three times to obtain quality devices. Based on the analysis, Problem Based Learning based learning materials that are taught have good quality at the stage of dissemination and the ability to solve mathematical problems learned by using Problem Based Learning devices is increased during the disseminate stage. The results of the analysis of the data obtained indicate that Problem based Learning materials can improve mathematical problem solving ability.
