In the information age, teachers are not the only source of information. The traditional teaching method brings problems such as passive learning and low interest in learning. This paper is aimed at studying how to analyze and study the hybrid teaching of English online and offline based on cloud collaboration and describing edge computing. This paper proposes the problem of mixed teaching of English online and offline. This question builds on the fundamentals of cloud collaboration. Therefore, the concept and related algorithms are expounded, and the case design and analysis of blended teaching are carried out. The experimental results show that in the follow-up questionnaire survey, online and offline blended teaching is applied to teaching practice. This brings the average academic performance of college English courses to 4.03. Compared with the previous academic performance, there has been obvious progress and improvement.
