The statistical population of the present study was all female students of the sixth grade elementary school in the city of Roudehen, who studied in the academic year of 1395-96. The research sample included all students in two classrooms selected randomly. Then, 35 students as an experimental group of origami, 35 people were selected as Dynamic geometry software and 35 controls as control group. The experimental groups were trained for twelve 40-minute sessions of mathematical education using Origami techniques and dynamic geometry software. The data collection tool included: (a) the Minnesota Space Visualization Test; and (b) the researcher's academic achievement test. To test the hypotheses, t-test and MANOVA were used. . The findings showed that the dynamic geometry software based on spatial and origami skills influenced the visualization of space and learning the mathematics lessons of students. In the t-test, the mean post-test scores of the dynamic geometry and post-test of origami software were significantly different with their pre-test. From these findings, it can be concluded that mathematics education, with the help of geometric and origami software, can improve spatial visualization and the learning of students' mathematics lessons.
