With the development of modern information technology, network education is becoming more and more popular, showing a trend of rapid development. Compared with traditional education methods, online education is conducive to breaking the restrictions of time and geographical environment on learners, obtaining richer multimodal education resources, and realizing personalized learning. However, in the actual network education, there are some problems such as the lack of students’ autonomous learning ability, the lack of effective learning supervision, the disharmony of classroom relations, and the lack of intelligence and emotion in human-computer interaction systems. In the face of this situation, this paper studied the teaching mental model in the network education environment, with a view to building a more harmonious human-computer emotional interaction system, so as to enhance the level of students’ positive emotional input and improve the efficiency of students’ learning. This paper drew the following conclusions through the analysis and evaluation of the application needs of the mental model of network teaching. 91.77% of the students thought their level of positive emotional input is not high, and 93.07% of the students thought their efficiency was not high enough. Most students were not satisfied with the human-computer interaction system in online education. Experts have high scores in the feasibility evaluation and effectiveness evaluation of the mental model of online teaching. The mental model of network teaching has obvious application demand, and has certain feasibility and effectiveness.
