فاعلية وحدة في الهندسة قائمة على نظرية التعلم المستند للدماغ لتنمية مستويات التفكير الهندسي لفان هايل لطلاب المرحلة الإعدادية

Abstract EN

The Research aimed to identify the effectiveness of the two units (areas and similarities and the opposite of Pythagoras and Euclid) based on the theory of brain-based learning in developingVan Hiele's Geometric Thinking Levels Among second-grade students of The Preparatory Stage Pupils' for the academic year 2019/2020.

To achieve the goal of the research, the semi-experimental curriculum was used.

The research sample consisted of an experimental group of (30) students, and a control group of (30) students from the Shaheed Muhammad al-Shazly preparatory School in Kafr al-Zayat center, gharbia governorate.

To collect Research data, tools and materials were prepared as follows:
- Card analysis of the content of units (areas, similarities, The opposite of the Pythagorean theorem and Euclid).

- Card analysis of the content of units (areas, similarities, The opposite of the Pythagorean theorem and Euclid) according to Behavioral Objectives.

- geometric thinking test based on first four Van Hiele's levels.

- Teacher's guide for the "areas, similarities, The opposite of the Pythagorean theorem and Euclid" and activity booklets.

The Research reached the following results:
There is a statistically significant difference between the mean scores of the two groups (experimental, and control) in the post- application of the geometric thinking test based on the first four levels of Van Hile's levels (visual - analytical - Informal deduction - Formal deduction) as a whole and at each level separately in favor of the experimental group, The research has proven that the two units based on the theory of brain-based learning are highly effective in developing geometric thinking of Van Hiele's levels among second-grade preparatory school students.

In light of this, the research made recommendations related to the necessity of increasing awareness of the parties to the processes of teaching and learning mathematics of the van hiele's geometric thinking levels in a variety of ways and suggested some future studies related to the variables of the current research and their development.
