The research aimed to identify the effect of using the hybrid learning strategy on the cognitive achievement and the level of technical performance of back crawl swimming, The researcher used the experimental method on a sample of (30) female students in the third year specializing in swimming at the Faculty of Physical Education Girls Zagazig University, and they were divided into two groups, one of them is an experimental group and the other is a control group of (15) students each, and among the research tools: cognitive achievement test - intelligence test Higher - A form for evaluating the level of performance of the stages of backstroke performance - the educational program using the strategy of the hybrid learning strategy. Among the most important results: 1- The educational program using hybrid learning has a positive, statistically significant effect at the level (0.05) on the cognitive achievement and the level of technical performance of back crawl swimming. 2- The learning style by command (explanation and model) has a positive, statistically significant effect at the level (0.05) on the cognitive achievement and the level of technical performance of back crawl swimming. 3- The experimental group that was taught in the educational program using hybrid learning outperformed the control group that was taught by the method of learning by command (explanation and model) in cognitive achievement and the level of technical performance of back crawl swimming. Among the most important recommendations: 1- Working on using the educational program using hybrid learning to improve the cognitive achievement and learn and master the back crawl swimming for the third year students majoring in swimming at the Faculty of Physical Education for Girls - Zagazig University.
