Abstract: As the concept of micro-lecture becomes clear gradually, the research focus of micro-lecture transfers from resources construction to its effective application into education. In order to explore the application mode of micro-lecture assisted instruction in major curriculum of science and engineering majors, the optics course is used as a practical research to promote its teaching reform. The results show that the vivid micro-lecture used as warmer of class is efficient to quickly catch students’ attention; micro-lecture plays a prominent role in solving students’ difficulties; for after-school tutoring, micro-lecture also has a positive effect. Micro-lecture brings a change to the traditional teaching mode, letting classes more attractive, students more interested and teachers more relaxed.
