The integration radically changes the essence of college English teaching, and therefore the traditional teaching mode has been challenged. In other words, information technology has become an integral part in today＇ s web-based college English teaching classroom. This paper attempts to read in detail about the Boyer＇ s teaching academic thought. Combined with the current situation of college English teaching, this paper discusses the feasibility of teaching academic thinking is applied to the English network teaching. A model is established by exploratory factor analysis and confirmatory factor analysis. Through the way of questionnaire to the research on the college English network teaching, so as to put forward the solutions and improve the quality of teaching.展开更多
