As researchers learn more about how childrens intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home. To begin with, all the factors that are

50、part of intelligence the childs understanding of language, learning patterns, curiosity are established well before the child enters school at the age of six. Study after study has shown that even after school begins, childrens achievements have been far more influenced by parents than by teachers.

51、This is particularly true about learning that is language-related.In view of their power, its sad to see so many parents not making the most of their childrens intelligence. Until recently parents had been intimidated by educators who asked them not to educate their children. Many teachers now reali

52、ze that children cannot be educated only at school, and parents are being asked to contribute both before and after the child enters school.
