Abstract
The purpose of this study was to obtain an overview of improving problem solving abilities and mathematical self-efficacy of students who received learning using a problem-based learning (PBL) model. The research method used is a quantitative research method. The type of research conducted is a quasi-experimental in the form of the nonequivalent pretest-posttest control group design. The population of this study were students of class XI in one of the high schools in Ciamis district, by taking samples using the purposive sampling technique. The instrument used in this research are test and non-test (observation sheet). Data collection techniques used in this study were pretest and posttest and observation sheet techniques. The subject that is presented as material is a linear program. The data analysis technique used parametric test, namely t test, Mann-Whitney non-parametric test and correlation test. The results of this research are (1) the increase in the mathematical problem solving ability of students who receive learning using Problem Based Learning (PBL) models is better than students who receive learning using conventional learning, (2) improving the mathematical problem solving ability of students who receive learning using the Problem Based Learning (PBL) model is better than students who receive conventional learning in terms of KAM, (3) increasing the ability of mathematical selfefficacy between students who receive learning using the Problem Based Learning (PBL) model is better than students who receive conventional learning, (4) there is a significant relationship between mathematical problem solving ability and mathematical self-efficacy.
