Abstract EN

The objective of this study is to know the effect of Modeling Strategic on fourth class students for the Mathematics Applied and their beliefs towards learninig and teaching Mathematics.

The researchers has put three null hypothesis, the first hypothesis is concerned with the students achievement.

The second hypothesis is related to diffrences between achievement of male and femael students and the third hypotheses related to the Student beliefs towards learninig and teaching .Mathematics.

All of them were tested The study sample consist of 55 students of mathematics, from the fourth stage (College of Education for Pure Science, university of Basrah), this sample divided randomly into two teams.

First team consist of 27 studenst and was taught due to normal method.

The second team is experimental consist of 28 studenst and was taught due to the strategic of Modeling.

These two teams were equal to each other into variables (age, previous mean in mathematics and in the .(intellechents Two research tools were conducted: one is for measuring the student's achievement, and the other for measuring student beliefs towards learninig and teching Mathematics.

The achievement test composes of (16) questions, type multiple choice), and the achievement test includes also four essay question).The validity of the test has been checked for its face validity, content validity, item difficulty coefficient, item discrimination and effectiveness of distracters.

So the researcher has extracted the reliability of the test by the equation of Cronbach’s Alpha.

As for the measuring of student beliefs towards learninig and teching mathematics, it contains (40) items, type (Forte araee; a graee, don’t certain; refuse and forte refuse), the researchers has confirmed the face and construct validity of the test, then he has estimated the test reliability coefficient by using .repeat test By the end of the experiment, tests of achievement and student beliefs towards learninig and teching mathematics were applied on them.

The data were :analyzed by spss programs.

The results of the study show that There are statistical significant differences among the grades means of the two research groups in the achievement, and in the measuring of student beliefs towards learninig and teching mathematics, and this was for the experimental .team There are no statistical significant differences among the grades means of the mail and femail in the item of achievement test which was taught due to the Modeling strategic.
