爱因斯坦曾经说过：“提出一个问题往往比解决一个问题更为重要。”在课堂教学中，我们已充分认识到学生质疑问难的重要性，注意了对质疑能力的培养。但在学生思维活跃、质疑问难的过程中，我们常常发现，学生的质疑有的是我们没有想到的问题，有些问题甚至出乎我们的意料，“? Einstein once said: “It is often more important to ask a question than to solve a problem.” In class teaching, we have fully realized the importance of questioning students and paying attention to the training of questioning ability. However, in the process of students 'active thinking and questioning and answering questions, we often find that some of the students' questions are problems that we did not think of and some of our questions are even beyond our expectation.
