اثر استخدام أنموذجي (بوليا و بيل)‎ لحل المسائل الفيزيائية على أداء طالبات الصف الخامس العلمي للمسائل الفيزيائية و تنمية اتجاههن نحو مادة الفيزياء

الملخص EN

This study aims to know what influence is there in using the two models of (Polya and Bell) for solving physical problems on the students performance at 5th scientific preparatory stage and to develop their attitude to wards physics .We chose the experimental design of three groups (two experimental and the other adjustable) .After making the groups are equivalent in some changes ,The first experimental group was studied according to Polya's model and the second according Bell's model, while the third (the adjustable) according the ordinary way .The three groups were taught ,the three chapters (three ,four and five ) in physics for 5th scientific class.

After finishing teaching ,we apply the two tools of the research which are solving physical problems contains (9) problems divided in to three problems for each chapter and the other is the measurement of direction towards physics which contains (42) parts.

By using the statistical instruments (the analysis of unique discrepancy , Scheffe value for knowing the difference among three groups and t.test for knowing the difference among mediators of the marks of the three groups.

The results showed that there is appositive influence of statistical significance for the two models in solving physical problems as compare with the ordinary group .It also showed that there isn’t a significant difference among mediators for the marks of the students of the three groups in measurement of attitude towards physics.

The study concludes that there is a development in direction towards physics at the students of the two experimental groups as compare with the ordinary ,but it doesn’t reach to statistical ,significant level .
