Hawthorne Factory in the suburb of Chicago, USA, is a factory that manufactures telephone exchanges. It has perfect recreational facilities, medical care system and pension system, but the workers are still aggrieved and the production situation is not ideal. Later, psychologists specially conducted an experiment on it, that is, in two years, experts had more than 20 thousand individual conversations with workers, stipulating that workers should patiently listen to their opinions and dissatisfaction with the factory during the conversation. This talk experiment has received unexpected results: the output value of Hawthorne factory has greatly increased. Every parent understands this truth, knows to pay attention to their children's inner world, and knows to have a heart-to-heart relationship with their children. But why don't children want to talk about it? "Jiao Jiao, this is the new teacher. Come and say hello to the teacher. " How does this sentence feel to children? "Mom found me a teacher again. Is she afraid that I will only play at home alone? Hum, this brother doesn't look big. Why should I call the teacher to say hello? " This inner monologue was told to me after I got acquainted with the little girl. Parents always talk to their children in an adult way, hoping that their children will understand. What I mean here is not tone, but way of thinking. Replace the opening sentence with "This is my Jiao Jiao". You two should meet first. "I think this little girl will have the psychology that her territory has not been violated and her mother attaches great importance to my feelings. I think if parents can do this, I believe no child will refuse to talk about this kind of venting pleasure. Ok, then I entered the formal class stage. For the above two questions, I decided to correct the little girl's psychological cognitive mistakes first. I said to the little girl, "My brother actually took the initiative to ask your mother to study with you, because my brother found that you have a different talent in mathematics than other children, but you need a special way to open it." The little girl blinked and said, "Really?" "Really, I believe my brother." In this way, this smart and lovely little girl began to have a little interest in mathematics again. I know that for a little girl, this interest cannot be easily erased, so in the process of teaching her, I will only criticize the mistake once, and if it is correct, I will praise it repeatedly, but is it really good?
