Can online classes replace teachers' offline teaching?

Although online courses are becoming more and more popular at present, personally, as a relatively new teaching mode, it is unrealistic to completely replace physical courses at least at present.

First of all, people are more or less inert in the process of learning new knowledge. If what they are learning is of great interest to them, the situation may be better, provided that the learners themselves have a certain awareness and ability of autonomous learning, such as adult students. Otherwise, for other students who are not very conscious of learning, such as primary and secondary school students, the learning effect of online classroom is not necessarily better than that of physical classroom. Teachers teach online, but they can't see what the children are doing. Some children are always teaching online classes, but they don't look at their teachers carefully in private and can't play a supervisory role.

Secondly, different teaching contents have different requirements for teaching methods. Some theoretical explanations, such as the derivation of formulas or accumulated knowledge, such as historical knowledge. No matter whether you study in an online classroom or a physical classroom, it should not have much influence on your grades. However, for those who tend to learn communication skills, such as oral English, online classroom still has some limitations compared with physical classroom: on the one hand, language application includes silent information such as expressions and body language besides audio information; On the other hand, it also has certain requirements for the interaction between teachers and students, which is difficult to achieve in online classroom.

Of course, the popularity of online classroom is inseparable from its advantages of saving money, convenience, wide choice and free time. Online classroom and physical classroom have their own advantages and limitations. I think instead of spending time discussing who will replace who, we should consider how to complement each other and provide learners with a more comprehensive and efficient learning experience.
