أثر أنموذج بوسنر على التغير المفهومي في تعديل التصورات البديلة عن بعض المفاهيم الرياضية لدى تلاميذ الصف الرابع الابتدائي

Abstract EN

This study aimed at identifying the effect of posner's Model for conceptual change on modifying the alternative perceptions of mathematical concepts for the 4^th grade pupils at the primary education stage.

For achieving this objective, two units (Regular and decimals fractions) of the 4^th grade's mathematics book were analyzed to identify the mathematical concepts and then construct a test for checking them.

A sample of (72) pupils from grade 4 was selected in Hail, KSA, which in turn was divided into two groups: experimental and control.

The experimental group was exposed to teaching mathematics using posner's Model while the control group was taught in the ordinary method.

However, the findings revealed that there were significant statistical differences among the means of the sample's marks of both groups when post-testing the alternative perceptions in favor of the experimental group.

Finally, a number of recommendations of which the significant one was teaching mathematics for the primary stages, as proved posner's Model as proved efficient for correcting the common errors of the mathematical concepts.
