The researcher used the experimental method on a sample of (40) students of the second year students of the Faculty of Physical Education Girls Zagazig University were divided into two groups, one experimental and the other control officer each (20). Students. Research tools include: Skill Tests - Cognitive Achievement Test - Educational Program. The researcher used the following statistical methods: - Arithmetic mean – standard deviation – median – torsion coefficient – T – test – correlation coefficient – improvement rates%. The most important results are: 1- The experimental group that used the Dalton method supported by mobile learning (M-Learning) over the control group that used the traditional method (verbal explanation and performance of the practical model), which shows its effectiveness and its effect on learning chest swimming. 2- Dalton method supported by mobile learning to take into account the differences between the individual students. Key recommendations include: 1- Using the Dalton method supported by mobile learning with other swimming methods and other sports activities. 2- The need to hold training courses for those teaching swimming, in order to identify the latest educational methods. 3- Attention to the teaching of cognitive content beside the skill content of swimming, which helps to expand the learner's perceptions, which facilitates the learning process.
