“问题”是数学的心脏。数学课堂上,教师需要为学生的学习设计出有效的数学问题,引领学生进行思考与探究。设计有效的问题,教师不妨“三问”。一、问题,激发学生思考的兴趣了吗?小学生的数学学习以直观思维为主,抽象思维能力正处于形成与发展阶段,因此教学时,教师要给学生提供丰富的感性材料,以此激发学生的求知欲望。设计问题,要建立在学生的认知发展水平和已有经验的基础上,注重问题的趣味性。 “Problem ” is the heart of mathematics. In mathematics classroom, teachers need to design effective mathematical problems for students’ learning and lead them to think and explore. Design effective questions, teachers may wish “three questions ”. First, the question, to stimulate students’ interest in thinking? Primary school mathematics learning to intuitive thinking, abstract thinking ability is in the formation and development stage, so teaching, teachers should provide students with a wealth of perceptual material, in order to stimulate students Desire for knowledge. Design issues, to be based on the level of cognitive development of students and based on existing experience, pay attention to the fun of the problem.
