Solving locus problems requires abstract thinking. It is difficult to remove this difficulty in traditional learning environments in which locus problems are solved with paper, pencil and ruler. The lack of visualization in traditional environment to solve locus problems demands alternative learning environments. Dynamic geometry software (DGS) with various functions is opening new windows to students and teachers for exploring geometry. In this study it is aimed to investigate the effect of

Quasi experimental design was used by determining Karadeniz Technical University Faculty of Education primary mathematics teachers as control and second education (evening) primary mathematics students as experimental group. Locus problems were solved in computer based environment with experimental group and traditional learning environment with control group. At the end of the practice an open-ended test consists of 8 items was administered to the both groups. The findings of the test indicated that DGS can increase students" abilities to conjecture and mathematical explanation in locus problems. In the light of findings it is determined that DGS-Cabri have a positive effect on students achievement on locus problems in general meaning.
