数学教学的核心应是培养学生学会数学地思考,而核心问题就是引领数学思考的航标。核心问题可以指为了探究知识的来龙去脉而在关键环节所提的指向性问题。数学问题的来源有多种方式,可以由教师根据知识的重点和难点为学生预设;也可以由学生自学后提出,并通过课堂交流重组生成。以核心问题为导向,有利于突出教学内容的关键节点,引导学生关注数学知识与思想的核心本质。
The core of mathematics teaching should be to train students to learn mathematics to think, and the core issue is to lead the mathematical aids in navigation. The core issue can refer to the problem of pointing at the key point in order to explore the ins and outs of knowledge. There are many sources of math problems, which can be preset by the teachers according to the key points and difficulties of knowledge. They can also be proposed by the students after self-study and generated through the exchange and restructuring in the classroom. Guided by the core issues, it is helpful to highlight the key nodes of the teaching content and guide students to pay attention to the core essence of mathematical knowledge and thinking.
