The networking and informatization of education are the inevitable trend of the rapid development of computer technology and educational reform. Compared with other subject education, physical education is less informationalized because of its practicableness. This paper puts forward the idea of sports blended learning based on Moodle platform, aiming at combining web-based learning and traditional physical education so as to promote the reform and development of physical education in colleges and universities. The paper first introduces the research background of Moodle platform and the related theories of blended learning and compares the differences between the college sports blended learning and traditional physical education in terms of teaching process, mode and design. Then based on this, it completes the teaching design based on Moodle platform. At last, it conducts an empirical research on the application of college sports blended learning to badminton teaching, verifying its feasibility and effectiveness in college physical education.
