摘要：The low effectiveness of mathematics learning is an indicator of the lack of activity of students in the learning process which has an impact on the low learning outcomes of students. Through the development of products based on problem-based learning activities students are expected to increase the effectiveness of mathematics learning. The research design used was the research on the development of Borg and Gall. The population in this study were all fourth grade students with a sample of two selected classes. The results of the study obtained a sheet of problem based learning based student activities that can be used to improve the effectiveness of mathematics learning. The difference test was obtained for the effectiveness of mathematics learning in the experimental class and the control class. Furthermore, the experimental class N-Gain was obtained by 0.64 with the medium category, while the control class N-Gain was 0.29 in the low category.
