The reason for this is the following：

1, kindergarten children themselves are mainly not learning knowledge. Going to kindergarten is actually a way for children to adapt to social life, rather than learning knowledge. Preschool children still play mainly. During this period, it is mainly to cultivate good eating habits, interest in learning and the ability to communicate with children. The online teaching function of kindergarten teachers is also limited.

2, children are not suitable for watching the screen for a long time. Today's children themselves are easily immersed in electronic devices such as mobile phones and iPad. Children should look at the screen in class, which virtually guides them to look at the screen more. And a class of about 30 minutes is harmful to children's eyes.

3. Children's concentration is limited, and children aged five or six are better. For three or four-year-old dolls, concentration is not enough to support online teaching mode. Children may really learn nothing by watching the teacher speak alone in front of the screen. Especially children in small classes, it is estimated that most of them can't sit still.
