Online courses are usually taught by video, but in this way, teachers and children can't have face-to-face conversations, teachers can't judge whether children's attention is concentrated or not through their classroom performance, and they can't judge whether children are growing up in class.

Second, there is a lack of effective management.

Because it is an online course, teachers can't directly grasp whether online students are focused on the classroom. There are many small videos on the internet that spoof students' class status. Although it can't be said that all students are, there must be some students who are like this. Therefore, this method requires children's self-discipline, and it is difficult for children without self-control to gain something from online education classes.

Third, lack of practice.

Online classroom can only impart knowledge, but can't lead students to practice in person, but practice is often the most interesting teaching content for students. Through practice, students can master what they have learned more deeply and have a stronger interest in the subject.
