The Research Aims to design the programmed concept mapping displayed on the computer in order to recognize its effect on Learning Breast stroke to the 3rd year students of Physical Education Faculty in Sadat city and To build a knowledge test to the 3rd year students to measure the knowledge acquisition of Breast stroke , The researcher used the experimental method of two groups; an experimental and control groups as it suits the nature of the research , the sample contents of (22) students , The researcher applied the oral intelligence test which Gaber Abdel Hamid & Mahmoud Ahmed Omar (2007) [5] prepared and which proven its honesty and persistence to measure the description it was prepared for, and the statistical treatment was performed , the results ; The Programmed concept mapping positively affects the learning of Breast stroke and the knowledge acquisitions level of the experiment group's students , The traditional technique (the oral explanation & the practical example performance) positively affects the learning of Breast stroke and the knowledge acquisitions level of the control group's students , The programmed concept mapping was more effective and positive than the traditional technique on the learning of Breast stroke and knowledge acquisitions level which indicates its effectiveness , Knowledge test prepared by the researcher has high honesty and persistence interactions and is appropriate for measuring the knowledge acquisitions level of the 3rd year students of Breast stroke that included (technical analysis of Breast stroke – common mistakes – law).
