Abstract
This research is motivated by the importance of mathematical problem solving skills and the fact of low mathematical problem solving skills of junior high school students. The aims of this study is to find out which students^ mathematical problem solving skills improving better, who use the Group Investigation learning model or students who use hands-on learning. This research used quantitative approach with quasi experimental research method. The research design used is non equivalent control group design. This research was conducted at in one of junior high school in Karawang, Indonesia by sampling using puposive sampling technique, so that taking two classes as research samples, each of which 40 respondents will be used as experimental class and control class. The data collection technique used in this study is in the form of instrument tests. The results of the data analysis showed that the improvement of mathematical problem solving skills of students who obtained the Group Investigation learning model is better than in students who obtain direct learning model.
