With the development of information technology, online and offline blended learning has become a universal learning form. In order to investigate and optimize the online and offline blended learning of English in higher vocational colleges, this paper introduces the CoI theory to analyze blended learning. First, design the questionnaire based on the three elements of the CoI theory. After analyzing the results of the questionnaire, conduct related experiments. In order to ensure the accuracy of the results, an experimental group and a control group are set up. After three months, most of the students in the experimental group have improved their performance. The experimental results show that blended learning has a certain positive effect on the improvement of vocational students’ English performance. In addition, it is found through research that there are certain differences in the promoting effect of blended learning on English scores under different scores. Therefore, this article puts forward some suggestions for blended learning.
