English summary The effect of using chroma-based virtual reality technology on Learn some basic volleyball skills Dr. Dalia Ahmed Raslan Shamandi Lecturer, Department of Games, Faculty of Physical Education for Girls, Zagazig University The current research aimed to identify the effect of using virtual reality technology based on chroma technology on learning some basic skills in volleyball. To achieve the goal of the research, the researcher used the experimental approach through the experimental design, which relies on the pre and post measurements of two groups, one of which is experimental and the second is a control one. Their number is (72) students, and the research sample was chosen by the intentional method, and their number is (60) students, and they were divided into two groups, an experimental group and a control group, the strength of each group is (30) students. Volleyball is under research, and the researcher has used virtual reality technology based on chroma technology on the experimental group, and the method used (explanation and model) on the control group, and after completing the data collection, the researcher subjected it to statistical treatments to obtain the results, and the researcher concluded that the experimental group was superior to the control group In learning some basic skills in volleyball for students of the Faculty of Physical Education.
