The purpose of this study is to explore the impact of classroom interactive Chinese teaching mode based on IoT technology on university students’ language learning. The study adopted the methods of questionnaire survey and experimental research, and selected two grades of Chinese teaching classes of a university in a city as the research object, totaling 120 college students, divided into experimental group and control group, and conducted a 6-month experimental teaching. The experimental group adopted the classroom interactive Chinese teaching mode based on IoT technology, and the control group adopted the traditional Chinese teaching mode. Before and after the experiment, the college students in the two groups were tested on their comprehensive language ability and questionnaire survey on their satisfaction with language learning, and at the same time, the college students in the experimental group were interviewed to collect their evaluations and feedbacks on the teaching mode. The experimental results show that the comprehensive language ability and language learning satisfaction of the college students in the experimental group are significantly higher than those in the control group, and both of them are significantly improved during the experimental period, which indicates that the teaching mode has a positive impact on college students’ language learning. The results of the questionnaires and interviews also showed that the college students had a positive attitude toward the teaching mode, believing that it could make the language classroom more vivid and interesting, increase the interaction between teachers and students as well as among students, and improve the efficiency and quality of language learning. This study provides theoretical guidance and practical reference for the reform and innovation of interactive Chinese teaching, as well as an outlook for further expanding the scope and extending the duration of the study.
