Constructing educational model of university physics experiment based on OBE concept, take the “Michelson interferometer measures wavelength of laser” experiments as an example, to carry out educational reform and pilot program of university physics experiment based on OBE concept. After two terms, it is proved that the teaching result of education model based on OBE concept is obviously improved than that of traditional, for example, students can take the initiative to learn, classroom atmosphere is more active, higher efficiency in class and so on.
