小学数学作为一门基础性的学科,它又是一门工具性很强的应用学科,小学数学的教学大纲中明确规定:小学数学的教学要以学生实际开始,遵循学生的年龄特征和认知结构水平,使学生在数学教学中获取必要的数学知识,形成数学的技能和发展学生的诸多能力,产生积极的创造思维,能够运用所学知识解决实际问题。数学课堂教学要实现这些教学目标,笔者认为,通过创设情境,让学生能够在情境中自主构建数学知识,这样学习才有效,课堂教学才高效。
Elementary mathematics is a basic subject. It is also a highly applied subject. The teaching outline of primary mathematics clearly stipulates that the teaching of primary mathematics should start with the actual students and follow the characteristics of students’ age and cognition The level of structure enables students to acquire the necessary mathematics knowledge in math teaching, form math skills and develop students’ abilities, to create positive creative thinking and to apply the learned knowledge to solve practical problems. In order to achieve these teaching goals in mathematics classroom teaching, I believe that by creating contexts, students can independently build mathematical knowledge in the context so that learning is effective and classroom teaching is efficient.
