Abstrak

In the learning process problem solving skills are still not good in mathematics learning. So as to overcome these problems a learning model that is more focused on students is needed to be more active in thinking on problem solving abilities, one of which is assumed to be able to improve it is the Problem Based Learning (PBL) Learning Model. This study aims to determine the increase in students' problem solving abilities using the Problem Based Learning (PBL) learning model compared to students who use conventional learning models. The method used in this research is a quasi-experimental method with quantitative approach and design. The instrument used in the test of students' problem solving skills was in the form of problem statements consisting of six items for each ability. The population in this study were students of class VIII of SMPN 1 Cisalak, while the sample was taken purposively with the results of consideration of the selected class VIII-B as an experimental class and class VIII-C as a control class. The experimental class was given learning by using the Problem Based Learning (PBL) learning model and the control class was given learning by using a conventional learning model. The data analysis technique used two difference test, linear regression test, one and two line ANOVA test. Based on the analysis and data processing results, it can be concluded that the improvement of students' problem solving skills is better in the Experiment class that uses Problem Based Learning (PBL) learning models compared to the control class that uses conventional learning models based on KAM
