Abstract


This research motivited by the low of students' mathematical problem solving abilities. The one of  alternative learning that is applied to improve the mathematical problem solving ability of students by using Open-ended approach. The purpose of this research was to find out whether there were differences in the improvement of mathematical problem solving abilities between students using Open-ended approach and students used the Problem-Based Learning model, as well as knowing the students' self-concept of mathematics learning with the Open-ended approach. The method was used in this study is a quasi-experimental method, with a pretest-posttest control group design research. The study was conducted in one of the junior high schools in Bandung Regency. The population in this study were all seventh grade students of one of the junior high schools in Bandung Regency, while the samples were students of class VII-A as an experimental class and class VII-D as a control class. The experimental class is treated with Open-ended approach and the control class is treated with Problem-Based Learning model. The instrument were a mathematical problem solving ability test, student questionnaire and teacher observation sheet. In this study quantitative and qualitative data were obtained. Based on the analysis of the results of mathematical problem solving tests, the conclusion is the improvement of students' problem solving ability using the Open-ended approach is no better than the students who use the Problem-Based Learning model in mathematics learning. Although the improvement of problem solving in experimental class students is not better than control class students, but at least the Open-ended approach has a positive effect on students' self-concept.


Keywords
