فاعلية برنامج مقترح قائم على نموذج أبعاد التعلم في تنمية التحصيل الأكاديمي و البراعة الرياضية لدى طلبة الصف الحادي عشر بسلطنة عمان

Abstract EN

The current study aimed to build a proposed program based on learning dimensions' model, and determine its effectiveness in developing the academic achievement and mathematical proficiency skills of eleventh grade students in Oman.

The study relied on the experimental method, based on a quasi-experimental design with two groups (experimental and control groups - pre/post measurement).

The study sample was comprised of an experimental group of n = 60 of 11th grade students of classes nr.

11/2 and 11/4 in Al-Nahda School in Salalah, Oman, and a control group of n = 60 of 11th grade students of classes nr.

11/1 and 11/3 in the same school.

The study tools consisted of an achievement test in the probability unit, and a test in mathematical proficiency.

The differences in pretest-posttest gains were analyzed using mean, standard deviation, t-test, eta-square (η2), and effect size.

The study found the effectiveness of the proposed program in developing the academic achievement and mathematical proficiency skills of the study sample students, with a strong impact size, as the results proved that there were significant differences at (α = 0.01) between the mean of the experimental and control group students in the post application of both the Achievement Test and the Mathematical Proficiency Test in favor of the experimental group.

The study recommended the need to develop the content of mathematics curricula, to include many activities that contribute to the development of mathematical proficiency skills, and higher levels of academic achievement for students.
