الملخص EN

The aim of this research is to identify )the effect of the Whitley model on the development of mathematical thinking skills for fourth graders) To achieve the research objective, the researcher put a zero hypothesis.

The experimental design was used for two groups the first is experimental groups and the second was the normal group.

The sample size was (56) pupils from the fourth grade pupils, by (28) students for the experimental group and (28) students for the normal group.

Where the researcher was balance between the two groups in variables according to(age, intelligence , parents' achievement, mathematics grade of the previous year, general average grade of the previous year, the skills of mathematical thinking), the researcher applied the pre and post testing of mathematical thinking skills, and after the data processing statistically by using the (t.

test) of the two independent groups, The results showed statistically significant difference between the average post-application of mathematical thinking skills of the experimental group students studied using the Whitley model and the control group students studied using the normal method.
