فاعلية استخدام الفيديوهات التعليمية الرقمية (اليوتيوب) في تحسين تحصيل التلاميذ الصم في مادة العلوم في الصف الثالث الأساسي
The aim of the research is to reveal the effectiveness of using digital educational videos (YouTube) in improving the achievement of deaf students in science in the third grade in the basic education stage. The research sample included (26) deaf students in the third grade of basic education at Al-Amal School for the Hearing Impaired, where the research sample was distributed randomly drawing into two groups. 1) the first is an experimental group consisting of (13) students. 2) and the second is a control group consisting of (13) students. The researcher adopted the quasi-experimental approach, and prepared the study tools represented by the achievement test for the science subject for the educational unit. The educational lessons were designed using the educational digital videos for the lessons of the educational unit. In order to find out the significance of the differences in the achievement between the students of the experimental group who were taught using digital educational videos and the students of the control group who were taught the same content in the traditional way, the researcher applied the achievement test to the students of the two groups and the results showed that there were statistically significant differences between the mean scores of the deaf students in the third grade from basic education in science in the experimental and control groups in the post-achievement test in science in favor of the experimental group. This indicates the effectiveness of using digital educational videos in improving the achievement of deaf students in science in the third grade of primary school. (Published abstract)
