The role of computers becomes an inseparable part of daily life, including as a media for learning mathematics, including making it easier to visualize 3D objects (building three-dimensional space). GeoGebra is software that can be used for mathematics education by combining geometry, algebra, and calculus. This research is an experimental research and the design used is the nonequivalent control group design. Sampling and sampling in this study using purposive sampling techniques. Based on the different test of the two average gain indexes, it was concluded that improving the problem-solving ability of students who studied using the GeoGebra-assisted problem-based learning approach was better than students who studied with conventional learning. The results of the attitude scale, it was found that in general students are positive towards mathematics learning by using the GeoGebra-assisted problembased learning approach. The results of the bivariate correlation calculation concluded that there is a positive correlation between students 'attitudes towards learning using the application of GeoGebra-assisted problem-based learning and improving students' mathematical problem-solving abilities.
