Implementation of emerging technology in sub disciplines of mathematics education provides a potential for educators to elaborate the capacity of digitized learning for human being. Spatial thinking is considered as a factor of scientific deduction from a multi disciplinary point of view. This paper reports a study aimed at exploring the effect of a 3D Modeling program on the spatial ability of the 8th grade students through an experimental research design. The study also focuses on the relation between the gender difference and spatial thinking. The study population was consisted of 82 8th grade students and divided into the control group (n=40) and the treatment group (n=42). The data in the study were collected through a qualitative research method. According to the findings of the research, the success rate of post test increased after the application in terms of differential aptitude, mental rotation and spatial visualization. On the other hand, irrespective of the relevant literature, female pupils were observed as better performers comparing to the males on post application of the measurement instruments.
