Nowadays, the information technology has been widely used in teaching activities, enabling more and more teachers to improve and facilitate their ways of teaching and communicating. However, how does IT usage exert influence on teaching self-efficacy, especially in university classes, still needs to be further studied. Based on Bandura’s self-efficacy theory, and literature review of flipped classroom which is the most representative and latest application scenarios of information technology, we try to identify applicable conceptual dimensions of teaching self-efficacy of university faculty and to construct a research model of influencing mechanism of IT usage on faculty’s teaching self-efficacy. Further study directions are suggested at the end of the research.
