In the context of modern education, it is essential for the sustainable development of the computer discipline to continuously explore the general process of course teaching and the strategy of class reform through the practice of new teaching methods. This paper discusses the practical application of the BOPPPS model teaching method in computer network courses and the strategy for class reform. The BOPPPS teaching model creates six teaching sessions in the Computer Networks course, which include an introduction, learning objectives, pre-test, participatory learning, post-test, and summary. Finally, we used student performance analysis and student questionnaires to understand the teaching effect of this teaching model. The study’s findings revealed that the average score of the case study questions in the experimental class was 3.32 points higher than that of the control class after adopting the BOPPPS teaching mode. During the learning process, both 33.5% and 39.5% of students expressed their ability to clarify and recognize learning objectives and think independently.
