提问是数学课堂教学中一种有效的教学组织形式,是一种最直接的师生双边活动,是引领学生索求知识、发现规律的有效途径。有效的提问是启发学生积极思考、调动学习主动性、提高课堂效率的关键。美国著名数学家哈尔莫斯说过:“问题是数学的心脏。有了问题,思维才有方向;有了方向,思维才有动力;有了问题,思维才有创新。”可见,教学中的“问题”对学生学习数学至关重要,它为培养学生良好思维和创新能力指明了方向。因此,
Questioning is an effective form of teaching and learning in mathematics classroom teaching. It is one of the most direct bilateral activities between teachers and students and is an effective way to lead students to seek knowledge and discover laws. Effective questioning is the key to inspire students to think positively, to mobilize the learning initiative and improve the efficiency of the classroom. Harmuth, a famous American mathematician, said: “The problem is the heart of mathematics. There is a problem, the direction of thinking is there. With the direction, the thinking is motivated. If there is a problem, the thinking is innovative.” “ Teaching ”Questions " is very important for students to learn mathematics, it is to develop students good thinking and ability to point out the direction of innovation. therefore,
