But the key question is, what is the performance and speed of mental rotation in boys and girls of different grades? Aims: The purpose of this study was to investigate the evolution of students' mental rotation. Method: This was a descriptive study. The statistical population consisted of Abik elementary and high school students in the academic year 2016-2017, who were selected by cluster random sampling method (400 male students (203 boys and 197 girls). Research tools include: Gannis & Kuwait Mental Rotation Computer Test (2015). Data analysis was performed using ANOVA and Tukey post hoc tests. Results: The results showed that the ability of children's mental rotation in the first to eleventh grades was significant (p= 0/000). In both tests, male students were better than female students (p= 0/001) performance and(p= 0/008 speed of action). The pattern of mental rotation showed greater differentiation of fourth- to sixth-grade students, but the rate of deceleration from first to sixth graders and then higher speeds were higher in practice. Conclusions: The model of mental rotation transformation can be an appropriate context for targeted educational programs. M3 ER -
