美国数学家哈尔莫斯说:“数学真正的组成部分是问题和解答,问题才是数学的心脏。”数学教学应围绕着问题来设计。一个好的数学问题离不开一个好的问题情境。数学问题情境是指学生在学习过程中出现了新的目的、新的问题,而已有的知识、经验、方法和手段已经不够用了,此时,他们就会有一种渴望达到目的、解决面临的问题的需求。在教学过程中,如果我们注意“问题情境”的创设,就会使学生产生渴望解决问题的需求,对教学内容发生直接兴趣。数学问题情境的创设,
Harmuth, an American mathematician, said: “The real part of mathematics is the questions and answers, and the problem is the heart of mathematics.” Math teaching should be designed around questions. A good mathematical problem can not be separated from a good problem situation. Mathematical problem situation refers to the students in the learning process has emerged a new purpose, new problems, and existing knowledge, experience, methods and means are not enough, then, they will have a desire to achieve the goal, to solve the problem The needs of the problem. In the process of teaching, if we pay attention to the creation of “problem situation”, we will make students have the desire to solve the problem and have a direct interest in the teaching content. Mathematical problem situation creation,
