2. Autism brought by online courses. The learning environment of online courses is a relatively autistic environment. Pure online learning is to communicate with each other through a set of network equipment, which virtually reduces direct contact with the crowd. Although the network can show the whole world in it, it is a world after all, and it should be admitted that it can completely replace reality. Therefore, we should organically combine online courses with other learning methods, and give full play to the advantages of each method, so as not to isolate the connection between individuals and groups while using online autonomous learning.
3. Other side effects brought by online courses. First of all, the study of online courses is prone to fatigue. Facing the fixed machine, staring at the screen for a long time will bring visual fatigue; When using the terminal, the fixed body, posture and sometimes boring learning content not only affect the learning effect, but also are often the main reasons why people give up online learning. This requires the designers of network equipment to consider from many aspects, and the designers of network courses should also pay special attention to the diversity of design. Secondly, people have become accustomed to the traditional listening and thinking in class, which will cause resistance to online course learning. Although multimedia courseware has rich means of expression, people also need a process of adaptation and acceptance.
