The Implementation of Problem Based Learning to Improve Student Mathematics Learning Outcomes of First Grade Students State Senior High School 2 Bandar, Simalungun

Abstract

This research has as purpose to boost the student learning process and improve student mathematical learning outcomes in first grade MIA 4 State Senior High School 2 Bandar, Simalungun second semester 2018/2019 within the subject of trigonometry (Sine and Cosine), to overcome a problem regarding the regulation of Sine Cosine after following learning material within the Problem Based Learning Model. This research used the class action research method. This research is a reflective and collaborative research which means the researcher collaborates with the mathematics teacher. The teacher takes a role as researcher carrying the action research. Action research in this analysis will be related to the Problem Based Learning model to improve student problem solving of Mathematics in the first grade of Senior High School. The learning process on every cycle has been improved more than before. During the first meeting, most students do not have any courage to state their own opinion and conclude the material they haves been taught, during the second meeting, there are more student who already have the courage to state their own opinion, the same thing happens during the third meeting. Based on the explanation of analysis result above, it can be concluded that the learning process has been improved to be a-better process after obtained action research.
