In recent years, due to the epidemic, the country is vigorously developing online teaching, which further promotes the development of hybrid English teaching. Online and offline hybrid teaching combines face-to-face classroom and online teaching. Offline traditional classroom and online auxiliary teaching can complement each other. However, in actual teaching, mixed teaching still suffers some defects, which can undermine the learning outcomes. In this paper, the Internet of Things information technology is used to study hybrid teaching. Firstly, relevant core concepts are clarified. After that, this paper designs an English online hybrid teaching model based on Internet of Things information technology and verifies the feasibility and effectiveness of this model through experiments. The results show that, compared with the simple mixed teaching, the average score of students’ final evaluation under this mode increased by 5.11 points. And the proportion of students with classroom interaction and autonomous learning also rose by 12.1%. This shows that under the promotion of Internet of Things information technology, the online hybrid teaching mode has great guiding significance for middle school English teaching.
