The application of information technology in the education business makes the traditional education mode gradually withdraw from the stage of history, and the online learning classroom begins to emerge in the teaching field. This paper builds an online learning community classroom for teacher-student relationships by combining MVC architecture technology with various online learning modes in the online classroom. FIAS interaction analysis and multiple regression models are used to quantitatively analyze interactive behaviors and changes in teacher-student relationships. The online learning community classroom model of this paper improves the average grade of the experimental class by 3.15 compared with the control class, with a p-value of 0.015, which is less than 0.05, and there is a statistically significant difference in the data. The teaching model of this paper can adjust the structure of teacher-student speech in teaching, and the teacher changes from “teaching alone” to “discussing with teachers and students”, and the students’ speech improves by more than 10%. In addition, this paper finds that for every one unit change in subject and teacher, the teacher-student relationship changes by 0.135, 0.261, and for every one unit increase in the teacher’s “creation of learning groups for grouping tasks”, the teacher-student relationship improves by 0.364. Similarly, for every one-unit increase in the teacher-student verbal interaction, the relationship between the teacher and the student increases by 0.142, 0.364, and 0.364, respectively. In summary, through the design and practical application of the online learning community classroom model in this paper, the functions and effectiveness of the system have been verified, which basically meets the needs of teacher-student interactive teaching.
