Let the children speak for themselves. The teacher asked leading questions and let the children tell themselves what to do. For example, before going out, the teacher asked the children how to pay attention to safety on the road. What should I pay attention to when I get to the library? What polite expressions should we use? How can I thank the staff for coming back? The teacher only needs to record the results of the children's discussion.

Go on. Every time I encounter a similar situation, I will organize children to discuss it. It doesn't matter if you can't do it once or twice. Children are like this, and it will have an effect after a long time.

The above is far better than the teacher's preaching.
