美国著名数学家哈尔莫斯曾说:“问题是数学的心脏。”从数学教学的角度看,如何设计一个好的问题,它的标准该是什么呢?教师应依据学生已有的知识背景和生活经验,努力创设具有调动性的问题情境、激发学生参与热情、点燃学生思维火花的启发性教学过程。但目前的课堂教学中,有的课堂提问存在一些问题。如教师在上课的过程中,提问随意,想到什么提问什么,有些过于简单;提问过 Harmuth, a famous American mathematician, once said: “The problem is the heart of mathematics.” "From a mathematical teaching perspective, how to design a good question, what is its standard? Knowledge background and life experience, and strive to create a mobilization of the problem situation, stimulate students to participate in enthusiasm, spark ignited student thinking spark teaching process. However, in the current classroom teaching, some questions in the classroom exist some problems.
