The research aimed to identify the effectiveness of teaching using the strategy of reverse learning supported electronically in the level of performance of swimming crawling on the back of the buds of (9-10) years, and the researchers used the experimental approach on a sample of (20) buds of swimming buds from (9-10) years were divided into two groups, one experimental and the other control strength of each (10) buds. Among the research tools: physical tests - performance evaluation form for crawling backstroke - educational program using the electronically supported flipped learning strategy.
