فاعلية نموذج مكارثي (Mc Carthy)‎ في تدريس الرياضيات لتنمية الاستدلال الرياضياتي لدى طلاب المرحلة الثانوية

Abstract EN

Study Title :The Efficacy of Mc Carthy Model in Teaching Mathematics to Develop Mathematical Reasoning among Secondary Stage Students The study aimed to identify : The Efficacy of the McCarthy model in teaching mathematics to high school students and its effect on the development of mathematical reasoning? To identify this effect, the researcher studied a theory about mathematical inferential thinking in mathematics.

The researcher conducted an experimental study.

The research sample consisted of (48) male and female students of the second year of general secondary school in Al-Wasta city schools, Beni Suef governorate.

And it was divided randomly, into two experimental and control groups, where the students of the experimental group (24 students) studied the unit "engineering and measurement" using the McCarthy model While the students of the control group (24 students) studied using the usual methods.

The study concluded that students who studied using McCarthy’s model outperformed students who studied using the usual methods of mathematical inference.

In light of the results of the study, the researcher recommends that attention should be paid to developing the content of the mathematics curriculum at the secondary stage according to the McCarthy Model criteria.

The study also suggested carrying out a study to determine the effect of the McCarthy model in reducing the phenomenon of school dropout.
