Abstract: Based on the current background of the teaching reform of public sports clubs in colleges and universities, an experimental study on the application of "SPOC + flipped classroom" mixed teaching mode in public sports dance teaching is carried out. The article adopts research methods of literature, interviews with experts, and experimental teaching. By constructing a "SPOC + flipped classroom" mixed teaching mode for public sports dance teaching, it implements and analyzes the differences between the "SPOC + flipped classroom" mixed teaching mode and traditional teaching mode in public sports dance courses in colleges and universities. The results show that the mixed teaching mode of "SPOC + Flip Classroom" has positive value characteristics for improving the autonomous learning of public sports dance students, improving the teaching effect of public sports dance teachers and optimizing the teaching place of public sports dance. Based on this, this paper puts forward some constructive suggestions, such as strengthening the construction of online and offline sports dance course resource database, strengthening teachers' training in online teaching course website, using online courses for teaching, online teaching safety awareness, establishing a better online teaching course supervision and management system, and improve the quality of public sports dance teaching in colleges and universities.
