أثر استخدام برامج الرياضيات الذهنية في تدريس الرياضيات في تنمية مهارات إجراء العمليات الحسابية لدى تلاميذ المرحلة الإبتدائية
The aim of the research is to identify the effect of using mental mathematics programs in teaching mathematics on developing the skills of conducting mathematical calculations skills among primary stage students, on two experimental groups (20) and control (20) in two schools of the Nasser educational administration schools in Cairo governorate, and equivalence was achieved between the students of the two groups in terms of some of the variables. The researcher prepared a test of the skills of conducting operations without using a calculator, and by processing the data using appropriate statistical methods, the results of the research concluded that the students of the experimental group that were taught using mental mathematics programs outperformed the students of the control group that studied in the usual way. And the previous foreign language in order to prepare a curriculum that includes study units that includes teaching mental mathematics programs in all stages of basic education, and to encourage primary school mathematics teachers to link the skills of performing arithmetic operations, which include numerical sense, mental computation, and approximation to the daily life of students, which he feels is important to them.
