Effectiveness of applied model unints supported by digitaalmultimedia on performance accuracy of some technical skills of volleyball juniors

Aim of research to identify the effectives of using applied model units supported by digital multimedia on performance accuracy of technical skills (underhand front serve – receive forearm serve- overhand pass (set) of volleyball juniors. Researchers used the experimental method with experiments design of two groups one of them experimental and the another one is central they were selected by purposed way of clubs juniors( ethad Jeddah-ahly jeddah) born in 2003 they were (30) juniors distributed in two groups one is experimental and the another one is control. Researchers used tests of physical components technical skills and photographer iq. The basic experiment has been from Monday 1/6/2014 to Saturday 1/9/2014. The results asserted excellence of experimental group on control one in performance accuracy of technical skills (underhand front serve – receive forearm serve- overhand pass (set ) of  volleyball juniors as a result of using the applied model units supported by digital multimedia .Researchers recommend by using the applied model units supported by digital multimedia to learn technical skills for volleyball juniors where have a positive effect on performance accuracy.
