Aim to study the construction and teaching mode of colleague sports MOOC platform. Method through the literature analysis method and inductive method to summarize the design and teaching mode of college sports MOOC platform. Conclusion is MOOC is a new type of teaching mode, and its importance is also becoming increasingly prominent. All colleges and universities should firmly grasp the development opportunities brought by the network era and then deepen the reform of college sports majors. The birth of MOOC provides a new model for the effective implementation of the reform of the sports major. Also, this model is the breakthrough point of the reform of college sports majors. Under the background of "Internet +", MOOC is integrated with the physical education of colleges and universities, and the two complement each other. This is very helpful to the optimization of physical education teaching mode and the improvement of the utilization rate of physical education teaching resources, and further promotes the deepening of physical education reform in colleges and universities. In recent years, China has made great achievements in the development of the Internet. In this context, the theme of "Internet + education" has been born. However, although it has received a lot of attention, the impact on physical education is not great enough. Lots of schools are still self-sufficient and unwilling to change the traditional teaching mode. This has made it difficult to achieve the desired effect in physical education. Teaching enthusiasm is lost, students cannot get the exercise they deserved. This phenomenon, which is called "point water type" and "putting sheep type", frequently appears in college physical education teaching, and has brought a negative impact on students' physical and mental qualities. Therefore, under such a status quo, teachers should actively carry out teaching reforms, strengthen their ability to apply new media and information technology, and constantly explore innovations in the teaching process to find new ways to improve teaching efficiency. The emergence and development of large-scale online open courses are inseparable from the popularity of the Internet. It is a web-based open course with a very large scale. The English abbreviation is MOOC, and it is usually called "2.0" online education. It specifically refers to the individual or an organization recording the teaching process into a video purposefully, and then publishing it on the Internet to enable people to learn online, while the learners can communicate and discuss difficult questions with the instructors online to promote a wider spread of knowledge. However, as sports course has certain special characteristics compared with other courses which this makes MOOC cannot directly replace traditional physical education. The mix of physical education and the Internet is not as simple as addition. It requires Internet platform and information technology to maximize the key role of the Internet in optimizing the allocation of sports resources, and then realize the deep integration of traditional physical education and MOOC teaching.
