The aim of the research is to identify, The effectiveness of the Geogebra program in developing the visual thinking and mathematical communication skills among the students of the fourth stage in the mathematics department. In order to achieve the objective of the research, the experimental method was adopted in the two groups (experimental and control). The number of members of the research sample (68) students from the fourth stage in the mathematics department was divided into two groups, one experimental, the number of its members (35) students studied according to the program, (33) students were studied according to the normal method, and the two groups were equalized by a number of variables. The visual thinking test was developed from a multiple choice type consisting of (25) experimental paragraphs, and a sports communication skills note card was constructed from (30) paragraphs. The results showed that the experimental group studied using the Geogebra program was superior to the control group in visual thinking and communication skills.
