The research aims at identifying the effectiveness of e-learning by using the mobile phone or the computer as browsers for the electronic platform to teach backstroke swimming techniques for the students of the Faculty of Physical Education by observing the ideal performance analysis of the world class backstroke swimmers and also the effect on the cognitive achievement of backstroke swimming by the students of the Faculty of Physical Education.
After completing the experiment period on the experimental group using the electronic platform in learning backstroke swimming – the performance level of the students in backstroke swimming was evaluated in the experimental and control groups – by giving scores for the arms movements, legs strokes and the overall compatibility of the method of backstroke swimming – by the judges to evaluate the performance – as well as the theoretical part of backstroke swimming to determine the effect of using the proposed electronic platform on teaching backstroke swimming for the students of the Faculty of Physical Education.

In light of the research results, the researcher concluded the following:
1- Using e-learning via the electronic platform in teaching backstroke swimming has improved the students' performance in backstroke swimming and had a positive impact on the cognitive achievement of the students of the experimental group.
2- Using the students of the experimental group for the electronic platform in learning backstroke swimming had a positive and statistically significant effect in the overall tests under research in favor of the experimental group.
