برنامج تعليمي على وفق استراتيجيات حل المسائل الرياضية و أثره في تنمية التواصل الرياضي لدى طلاب المرحلة المتوسطة

Abstract EN

The research aims at recognizing the impact of a training program based on problem-solving strategies and the resulted development of a mathematical communication among secondary school students.

verified in terms of validity, reliability and psychometric features.

The pretest was applied to the students, and after getting the results, the program was applied then to develop the mathematical contacts among them during the first semester (2018-2019).

There were 5 lessons per week, each lesson lasted 45 minutes.

After that, the post-test was applied to them.

The results showed that there are statistical differences at the level of (0.05) on behalf of the post-test.

The main statistical means used in this study were t-test done for one sample, t-test for two unconnected samples, and tow connected samples, Alpha Cronback coefficient, coefficient of agreement, and Pearson coefficient correlation.
