There is no statistically significant difference at the level of significance (0.05) between the average scores of the experimental group students who will study mathematics according to the Treagust model and the average scores of the control group who will study the same subject according to the usual method of the pivotal thinking test.
The research community that represents intermediate and secondary schools for girls was identified within the General Directorate for Education of Al-Rusafa First. The research sample was chosen from (64) female students of the second intermediate grade in Al-Asma'i Intermediate School for Girls intentionally, and the sample was divided into two groups, an experimental group and a control group. The experimental group included (33) A student studied according to the Treagust model, and the control group included (31) students who studied according to the regular method.
Equivalence was made between the two research groups in some variables (previous achievement, parents ’academic achievement, previous information, intelligence, and axial thinking), and two tests were built:
The pivotal thinking test: it consists of (24) paragraphs of the objective type in its final form.
The experiment was applied in the first semester of the academic year (2020-2021) at the rate of (6) lessons per group per week. The researcher studied the two research groups on her own after formulating behavioral goals for the three semesters and for the six levels of Bloom's cognitive field. The number reached (106) goals. (20) Teaching plan for each group that included research topics.
Appropriate statistical analyzes were carried out for the test results, as the Keoder-Richardson equation (K-R20) was used to calculate the coefficient of the stability of the axial thinking test, the coefficients of difficulty and discrimination, the effectiveness of alternatives, the Pearson correlation coefficient and the t-test for two independent eyes, and the results indicated the superiority of the experimental group over the control group students. In the axial thinking test.
