الملخص EN

The present research aims at measuring second intermediate class students’ scientific reasoning in mathematics; and determining the impact of Denis’s module on procuring; scientific reasoning; and retention.

The research sample was second intermediate class pupils from intermediate schools of the General Directorate of Education of Thi-Qar governorate.

The research sample included (60) pupils.

Thirty pupils represented the experimental group and the other thirty represented the controlling group.

The researcher balanced between the two groups in terms of age variable, previous procuring, and the educational level of the parents.

The researcher prepared a thirty-item test whose validity had been approved by a jury.

However, the test reliability had been approved by re-test technique, where the reliability coefficient recorded (0.70).

The researcher prepared a thirty-item measure for scientific reasoning whose apparent validity was approved by a jury, and whose reliability had been approved by re-test technique, where the reliability coefficient recorded (0.91).

As for the statistical aids, the researcher used:- Pearson’s correlation coefficient, T-test coefficient, and Cronbach’s Alpha.

The researcher reached at the following results: 1.

There is a statistically significant superiority for the experimental group which studied according to Denis’s module over the controlling group which studied according to the normal method of procuring.

2.

There is a statistically significant superiority for the experimental group which studied according to Denis’s module over the controlling group which studied according to the normal method of scientific reasoning.

3.

There is a statistically significant superiority for the experimental group which studied according to Denis’s module over the controlling group which studied according to the normal method of retention.

The researcher recommends the following:- 1.

Adding Denis’s Module to the items of Mathematics Teaching Methods course for students of the college of Education.

2.

Designing a training programme for Mathematics teachers to teach according to Denis’s Module.

3.

Mathematics supervisors should urge mathematics teachers to use Denis’s module.
