In the context of the pan-media era of “Internet +”，it is necessary to make new explorations of physical experiment of college based on online teaching platform and social network．In order to allow students to learn physical experiments of college more scientifically and efficiently，we should highly integrate experiments and internet information technology to create smart classes，demonstrate physical experiment phenomena through new media and operation precautions，expand teaching resources，reform experimental teaching modes，and improve the quality and of efficiency experimental teaching．This kind of innovative smart class based on “Internet +”can not only stimulate students’interest in learning，promote students to master scientific and reasonable learning methods，but also exercise the practical ability of college students in physics experiments，thereby cultivating students’sense of innovation and scientific literacy．
