Research on the Innovation of English Teaching in Colleges and Universities under the Background of Internet

The intelligent development of society has brought new impetus to English teaching in universities, which has led education workers to update their education philosophy and realize the integration and innovation of teaching methods. This paper takes advantage of the Internet’s advantages in blended teaching as the entry point and constructs a blended learning model for English teaching. To verify the innovation and practicability of the model in teaching, the evaluation index system of the blended learning model of English teaching is constructed on the basis of the CIPP model, and the variance maximization idea is used to combine the weights of principal component analysis and entropy weights, which guarantees the scientificity and objectivity of the weights of the evaluation indexes. The blended learning model of teaching was quantitatively analyzed in terms of teaching objectives, programs, processes, and effects using examples. The results show that the blended learning model of English teaching is conducive to improving the level of English teaching in colleges and universities, and its overall evaluation score is 3.59, which is a good level. Each first-level index in the evaluation index system has a score range of 3.2 to 3.7, which is a good level overall. Under the background of the Internet, the introduction of blended teaching can effectively innovate English teaching, and on the basis of focusing on students’ learning behaviors, we should pay attention to the guiding role of teachers so as to boost the quality of English teaching.
