Strategy	Content
Demonstration	In the teaching process, it is child-centered and combined with the environment. In the teaching process, there are specific teaching aids, teaching postures, and teaching contents for children to imitate or follow and repeat.
Tips-demonstration	In the process of teaching, the teacher asks the children to wait systematically or delay for a short time before giving assistance, so as to encourage children to actively interact.
Time delay	In the process of teaching, the teacher asks the children to wait systematically or delay for a short time before giving assistance, so as to encourage children to actively interact.
Random teaching	The purpose is to trigger more complex language types and higher language skills for specific subjects, so as to improve the ability of conversation and prolong the time to talk about the subject.
