The result of preliminary study on junior high school students in Ambon city shows that students thinking ability is relatively low. From 160 students from 4 junior high schools in Ambon city that became sample, it was found that 90,63% had high thinking ability in low and very low category, and only about 1,25% of students who had good ability. Primarily, this is due to the weaknesses of learning that involve less of problem solving processes, including high order thinking processes. This research is aimed to develop a new learning model called problem solving based learning model. There are six major components, they are: (1) syntax, (2) social system, (3) principles of reaction, (4) support system, (5) instructional effect and nurturant effect, and (6) evaluation system. This model consists of 7 (seven) phases, they are: (1) the introduction, (2) material discussion, (3) problem solving, (4) presentation, (5) extension of problem solving, (6) presentation, and (7) closing. Problem presentation and problem solving process in this model is started from simple to complex one. In this model, learning activities are directed at problem solving which is believed will be able to stimulate students thinking and develop highorder thinking skills. Key words: Problem Solving Based Learning Model, High Order Thinking.
