Information technology, especially the Web, is creating tremendous opportunities in education. With the Internet's rapid growth, the Web has become a powerful and interactive medium of teaching and learning in physical education. We have the question "What does it take to provide the best and most meaningful learning environments for learners?" For answer this question, we have opened a course(swim 5; Butterfly) supported by Webclass serviced by CTL(Center bfor Teaching and Learning) at S Univ. First, We described the Webclass is applicable for not only other classroom classes but also physical education classes and there are much more difficulties solved. Second, there needs some connection between University Adminstration and Webclass(CIL) so as to be convenient for teachers. Physical educators who want teach better will prepare their work well by this case study.
