[...] if the network course interface is not equipped with high usability, it is difficult for network course education to continue.[...] the usability analysis of network course interface is of great significance for the optimization of network course learning. If the network course interface is unable to attract the interest of learners, they may terminate their study immediately.[...] the usability analysis of the network course interface is important for the optimization of network course learning (Allen, 2006). In this way, the effect of the network course education cannot be fully exerted.[...] the design and development of network courses requires a great deal of money and manpower (see Figure 2).(4) Fault tolerance: Since students and teachers do not necessarily have a good network technique level, the network course interface itself needs to be equipped with the ability to prevent students and teachers from performing incorrect input and incorrect operation.
