Abstract

The current research aims to know "the effect of the Lesh model on the mathematical communication skills and visual thinking of fifth-grade primary students". The research sample consisted of (40) students distributed to two groups, one is experimental and the other control, where each division includes (20) students. Furthermore, the two groups were rewarded in time age, intelligence test, previous knowledge test and the general average for the previous school year. Two tests were prepared,  the first one was for the mathematical communication skills, and the second for visual thinking, by (18) objective items for each test, and face validity was performed for them, and the reliability coefficient of the two tests was calculated using the (test and re-test method) and for both variables. Moreover, the validity value for the first test reached (0.88), while the validity value for the second test reached (0.91), while the statistical package for social sciences (SPSS) was used to analyze the results. Finally, the research results showed that there were statistically significant differences at the level of (0.05) between the average scores of the experimental group that studied by the Lesh model, and the control group for the experimental group.
