Pyramidal Hologram technology in the form of a digital booklet and its impact on some defensive skills and cognitive level in handball

The aim of this research is to use hologram technology to support a digital booklet and to know its impact on the performance of some defensive skills and cognitive level in handball. The researcher used the experimental method using the experimental design of the pre and post measurements of two experimental groups and ,The sample included a number (44) students were withdrawn (12) students as a exploratory sample and the other of sample was divided into two groups, one experimental and the other control each of them (16) Students of the Second Division of the Faculty of Physical Education for Boys Benha University , researcher used software to design the digital booklet and the videos By Hologram ,the most important results indicated differences between the two pre and post measurements of the experimental and control groups for the post measurement, and the differences between the two post measurements between the experimental and control groups for the benefit of the experimental group, and ratios The change and improvement of the skills tests and the cognitive test were higher than the group for the training of the control group and the learning using the technology of hologram achieved the highest benefit to students and is considered to be a modern technology used in the educational process
