فاعلیة استخدام النمذجة في تنمیة مهارات حل المسألة الریاضیة لدى التلمیذات بطیئات التعلم بالمرحلة الإبتدائیة
The aim of this research is to study of the effectiveness of the use of modeling in the development of mathematical skills, to solve the issue (to understand the issue -develop a plan to solve the issue - the implementation of the solution and to ensure health solution) related with slow-learning students in primary school in the Asir region of Saudi Arabia. This paper is based on procedures with quasi-experimental approach, that is based on the design of experimental and control groups, in which the first group received the treatment trial, was the use of modeling in the teaching of Chapters VII and VIII of the subject of Mathematics of sixth-grade primary school, While the second group received treatment, was control group, using the usual method of teaching. And for the experiment was carried out by selecting (95) school girls with slow- learning, where the number of the experimental group is (45), while the number of the control group is (50). I have reached to the conclusion to the effectiveness of the use of modeling in the development of skills to resolve the mathematical issue, as well as the subskills (to understand the issue -to develop a plan to resolve - the implementation of the solution – to ensure health solution) related with slow-learning students of primary school, where statistician has been found so far at the level (0.01 ) between the average score for the students of the experimental group and the students of the control group, to test the skills of resolving the mathematical issue as a whole , as well as the sub-skills components individually. In the light of these results, some of the recommendations is presented, such as, including the training of teachers of mathematics at the primary level in the use of modeling in teaching to develop the skills resolve the matter with the mathematics students, especially slow-learning students.
