Online courses are becoming more and more popular. Can it replace offline classes soon?

At present, a major event in the field of education is the popularity of various online courses, especially during the COVID-19 epidemic, which provided fertile soil for the development of online courses. In order to minimize the impact of epidemic prevention and control on students, schools all over the country have put forward the concept of suspension of classes. From universities to primary schools, online classrooms have been vigorously promoted, allowing teachers to take classes online and provide guidance to students. All kinds of training institutions seize the opportunity to develop it as an industry. From the advertising intensity of online courses, we can see their importance. Many training institutions do not hesitate to invite famous teachers to broadcast live online classes to expand their influence and students.

Online classes are becoming more and more mature. Not only can you assign homework, check homework, correct homework, and take exams, but you can also have functions such as signing in, roll call, and raising your hand in class. Even because some online courses are too powerful, they are scolded by the majority of students, thinking that their management is too strict, and calling on students to lower their program scores. However, it still can't stop the tide of online classes. In some places, the province has even made efforts to promote online courses. For example, the classrooms in Guizhou are officially built, and classes can be held on TV, mobile phones and computers. It can be said that there is no dead angle in 360 degrees. Judging from the quality of online courses, we can see that the preparation work is sufficient. From the production of ppt, to the arrangement of homework, to the setting of question and answer session, it is very attractive. Many people think that online classes are of higher quality than online classes. So in this case, is it possible for online classes to replace offline physical classes? Bian Xiao thinks this is irreplaceable for the following reasons.

First, emotional input is difficult to have an effect. As we all know, teaching and educating people are linked. Education is a job that needs emotion. Classroom is not only the exchange of knowledge, but also the exchange of feelings. In terms of class quality, the online curriculum may indeed be better and higher than some teachers in other schools. However, the online classroom puts students and teachers at both ends of the network, and the communication between teachers and students is not sufficient, even if there is not much communication, there is no emotional communication, so it is impossible to communicate. Working in the line of some training institutions requires thousands of classes in one class. How do teachers communicate? Only from this point can we be completely sure that online classroom can not replace the real classroom, but can only be used as a supplement to the real classroom.

Second, the classroom effect is difficult to guarantee. Why do you say that? Teaching should pay attention to the effect. A good teacher does not mean a good classroom effect. Classroom effect requires in-depth interaction between teachers and students, but online classroom often can't. Because it is difficult for students to be single-minded in online classroom teaching, it is impossible for teachers to monitor every student's situation, while physical classroom teachers can monitor every student's situation. Online classroom depends entirely on students' consciousness to ensure the learning effect. After all, students can feel the situation of teachers at both ends of the network cable, but teachers can't feel the situation of all students. The teacher doesn't know if he has listened carefully, if he has any other tricks, if he is doing other things, if he has listened carefully and if his thoughts can keep up. In fact, this teaching mode can be said to be a return to the previous spoon-feeding teaching, and no matter what tricks he takes, this fact cannot be changed.

Third, it is difficult to take into account the academic situation. As we all know, the first thing to analyze in teaching is the learning situation, which is the basis to ensure the teaching effect. Even in a school, students will be divided into different types and categories for targeted teaching. For example, which class of students speaks more thoroughly, which class of students is only suitable for telling them basic knowledge, which class of students makes faster progress, and which class of students definitely makes slower progress. In these cases, online courses can't take care of both at all, but can only be generalized, and the overall effect is debatable.
