In the process of the game, the teacher did not control the children in their own field of vision, and did not give them the process of gradual adaptation. Teachers did not pay attention to children's fatigue, remind children to rest and add water, or relax. In the observation, most kindergartens organize children to go out for activities in the morning. When children have outdoor activities, many teachers will gather together to chat, fail to control the scope of children's activities in their own field of vision, and completely let go of children.
