Abstract
The purpose of this study was to determine the differences in the increase in students spatial thinking abilities; differences in achievement of spatial thinking skills based on students Early Mathematics (PAM) knowledge; and the difference in increasing the mathematical character of students between before and after mathematics learning using the Cabri 3D software with a scientific approach. This study uses quasi-experiment, the experimental class uses Cabri 3D software with a scientific approach and the control class uses conventional learning. The results showed that: there were differences in the increase in spatial thinking skills; there are differences in achievement of spatial thinking skills based on PAM and there is interaction between PAM categories of students with learning in achieving students spatial thinking skills; there is a difference in the improvement of students mathematical characters between before and after mathematics learning using the Cabri 3D software with a scientific approach. Mathematics learning using Cabri 3D software with a scientific approach is one alternative to improve spatial thinking skills and mathematical character of students
