1, experimental hypothesis h:
H 1: The frequency at which positive motivation can promote children's communication.
H2: Positive motivation can improve the quality of children's communication.
Variable operation: positive motivation (teacher praise); Frequency of communication (observing the number of interactions between children and their partners within one hour); Communication quality (evaluation of participants by partners after interactive activities)
Subjects: A kindergarten 1 class randomly selected a large class, a middle class and a small class as experimental classes; Select the corresponding class as the control version, the number of the two classes is almost the same, and so are the teachers (to be honest, the experimental research is more difficult, strictly speaking, it is quasi-experimental)
Experimental treatment: training teachers, teachers in the experimental class began to praise children, while the control class did not praise them. According to the operation form, we looked at the dependent variable after praise, and confirmed or falsified hypothesis 1 and hypothesis 2.
