有句话说,医生是靠病家的痛苦而生存的,教师是靠学生的无知而工作的。这虽属调侃之语,却也揭示了一个重要的事实:教育是建立在师生“差异”的基础之上的。但是,差异不仅是文化知识上的,还有心理认 There is a saying that doctors live by the pain of the sick family, and teachers work by their ignorance. Although this is a language of ridicule, it also reveals an important fact: Education is based on the difference between teachers and students. However, the difference is not only cultural knowledge but also psychological recognition.
