THE EFFECT OF PROBLEM BASED LEARNING MODEL ON STUDENT’S LEARNING OUTCOMES ON GEOMETRY OPTIC TOPIC
Abstract
This research have purpose to know the effect of problem based learning model on student’s learning outcomes and student’s learning activity on geometry optic topic. This research is a quasi experiment using control group pre-test-post-test design. The sampel of theses research consisted of two classes, each contains 30 students. By using total sampling, one class is made as experiment class that uses problem based learning model, and one class is as control that uses conventional learning model, so class XI science -1 as control class and class XI science -2 as experiment class. The instrument used was a test of learning outcomes in the form of students learning outcomes in the form of 7 essay test. In the experimental class the average activity of students in the three meeting, are 62.44, 70.67 and 77.78. The learning activity have increase during three times meeting and have average value 70.33 and have good category. The data obtain so problem based learning model can increase learning activity on geometry optic topic of SMA Negeri 2 Lintongnihuta class XI science second semester A.Y. 2017/2018. The value of the average post-test experimental class was 75.13 and control class was 67.10. Hypothesis with t-test shows the result there was a significant effect of problem based learning model on student’s learning outcomes on geometry optic topic of SMA Negeri 2 Lintongnihuta class XI science second semester A.Y. 2017/2018.
Keywords: Problem based learning model, conventional learning model, learning outcomes, quasi experiment, learning activity.
