The Development of Problem Based Learning Model to Construct High Order Thinking Skill Students ’ on Mathematical Learning in SMA/MA

This research is a development research of learning model that aimed to develop problem based learning model to construct high order thinking skill of students on mathematical learning in SMA/MA. The experiment subject and dissemination were the students in the first grade of SMA/MA in three subprovinces of North Sumatera, those are SMA Swasta Yapim Taruna Stabat subprovince Langkat, SMK Negeri 6 Medan, SMA YPK Medan, and MAN Lubuk Pakam subprovince Deli Serdang. The data collecting instruments in this research are questionnair, observation paper, interview guidance paper, mathematics book for students in the first grade of SMA/MA, mathematics book for teacher guidance and pre- and posttests instrument. This model development was adopted from Thiagarajan, Semmel & Semmel model. Concretely, learning model was implemented to increase high order thinking skill of SMA/MA students for solving mathematical problem. Moreover, this research aimed to produce mathematics book for students in first grade of SMA/MA and mathematics book for teacher guidance that consist of structured steps for solving mathematical problem based problem solving to construct high order thinking skills. The experiment result shown that there is a significant improvement of mathematical problem solving skills of student
