Second, there is a lack of face-to-face communication between teachers and students. The new curriculum reform teaching model is not easy to develop, and there is a lack of effective communication between teachers and students and between students. It is difficult to guarantee the effectiveness of teaching effect.
Third, classroom feedback will be discounted. Online teaching, without the on-site guidance and supervision of teachers, students' learning dynamics can not be controlled, especially those students who lack self-discipline and have relatively poor foundation, and the effect will not be good. What's more, after-school homework is inevitably perfunctory and plagiarized, and after-school feedback will lose its effectiveness, which naturally cannot guarantee the teaching effect.
Fourth, it is not good for your health. From the perspective of students' health, online teaching has a great influence on students' eyesight. The equipment for online teaching is a computer or a mobile phone. Students staring at the screen all day will pose a threat to their eyesight. Those middle and senior students have to stay in front of computers or mobile phones for at least 6 hours every day, which has a great influence on their eyesight and even their health!
With the advent of the Internet era, online teaching has become an important part of the education industry. The most important thing is to make full use of all advantages, reduce the influence of disadvantages and constantly improve the teaching mode.
