The research aimed to get acquainted with the impact of this research to design an educational program using Edmodo educational platforms and know its effect on the level of performance, time to start, rotation and achievement motivation in swimming crawling on the abdomen, and the researcher used the experimental approach on a sample of (24) students in the fourth group at the Faculty of Physical Education Girls - University Zagazig were divided into two groups, one of which is an experimental group (educational platforms), and the other is a control group (learning by orders) consisting of (12) students, and among the research tools: skill tests - high intelligence test - achievement motivation scale - tests of starting skills and parents Run in the crawl swimming on the abdomen - the proposed educational program using educational platforms, and the researcher used the following statistical methods: mean - standard deviation - median - torsional coefficient - simple correlation coefficient - "T" test - improvement ratios. Among the most important results: 1- Edmodo educational platforms contributed in a positive way to improving the level of performance, start time, rotation and achievement motivation in swimming crawling on the abdomen. 2- Traditional learning (verbal explanation and performance of the practical model) contributed positively to learning the skills of starting and turning in swimming crawling on the abdomen, while not contributing positively to improving the motivation of achievement. 3- The experimental group that used Edmodo educational platforms outperformed the control group that used traditional learning (verbal explanation and practical model performance) in the level of performance, start time, rotation, and achievement motivation in crawling swimming on the abdomen.
