数学是数学问题的科学,是数学问题提出与解决的科学。数学问题产生于数学情境,数学情境是从事数学活动的环境,产生数学行为的条件。在课堂教学中,课堂提问是一种行之有效的手段,也是所有的老师普遍采用的一种课堂组织形式。设置有效的数学情境和课堂问题,能充分调动学生的学习积极性,让学生积极参与到教与学的互动过程中来,让学生变成课堂的主体,在这过程中实现知识和能力的双丰收。然而,很多时候,教师预设的问题流于表面,不能环环
Mathematics is the science of mathematics, and it is the science that mathematics problems propose and solve. The mathematics problem arises from the mathematical situation. The mathematics situation is the environment that is engaged in the mathematics activity, and the condition that produces the mathematics behavior. In classroom teaching, questioning in class is an effective method and is also a form of classroom organization commonly used by all teachers. Setting up effective mathematics situations and classroom problems can fully mobilize the students’ enthusiasm for learning, enable students to actively participate in the interactive process of teaching and learning, and make students become the main body of the classroom. In this process, the realization of the double harvest of knowledge and ability. . However, many times, the teacher’s default problems flow to the surface and cannot be ringed.
