Aim of the research: Facilitating The Learning of Butterfly Stroke for the students'   Research hypotheses: 1. There are significant differences between the pre and post measurements of the experimental group in some physical variables, the level of knowledge acquisition, and the quick learning of the butterfly swimming of the students at the Northern Borders University, in favor of the pre measurement. 2. There are significant differences between the two pre and post measurements of the control group in some physical variables the level of knowledge acquisition, and the quick learning of the butterfly swimming of the students at the Northern Borders University, in favor of the pre measurement. 3. There are significant differences between the two post measurements of the experimental and control groups in some physical, the level of knowledge acquisition, and the quick learning of the butterfly swimming of the students at the Northern Borders University, in favor of the experimental group. Research Methodology: The researcher has used the empirical method, using the experimental design to two groups, an experimental group and a control one, depending on the pre and post measurements appropriate to the nature of the study. Research population: The research population was chosen of the students of the University of the Northern Borders, Saudi Arabia - Ar'ar who are enrolled in the courses of swimming for the academic year 2013/2014, with a total number of 80 students. Research sample: The sample was randomly selected of the students of the University of the Northern Borders in Saudi Arabia, Ar'ar- total number of (52) students were picked up (40) students were The basic research sample that have been divided into two groups as an experimental group and control group
