思维起源于问题,问题是数学的心脏。著名教育家陶行知先生说:“发明千千万万,起点是一问……智者问得巧,愚者问得笨。”创新教育要求数学教师把“问题”作为教学的出发点,提出带有启发性和挑战性的问题。作为教师要考虑问什么,什么时候问。如果教师准备不足,想问什么就问什么,就会使课堂显得松散起不到提问的作用。所以提高数学课堂的有效性需教师精心设计课堂提问。 Thinking originated in the question, the problem is the heart of mathematics. Mr. Tao Xingzhi, a famous educator, said: “The invention of tens of millions, the starting point is a question ... ... smarter asked dexterity, fool asked stupid.” Innovation education requires mathematics teachers to “problem ” as a starting point for teaching , Raised enlightening and challenging questions. As a teacher to consider what to ask, when asked. If the teacher is short of preparation, what he or she wants to ask will make the class less likely to ask questions. Therefore, improving the effectiveness of math classrooms requires teachers to carefully design the classroom questions.
