创设问题情境是课改以来广泛被数学教学应用的一种有效的教学方法,目的就是要加强师生之间的互动,鼓励学生在自主思考问题、解决问题的过程中掌握基本的数学知识,提高学习效率。因此,本文就从以下几个方面入手对如何借助问题情境的创设来构建高效的数学课堂进行论述。一、在数学导入环节中创设问题情境导入环节是一堂课的第一步,也是决定高效课堂顺利实现的 The establishment of the problem situation is an effective teaching method widely used by mathematics teaching since the curriculum reform. The purpose is to strengthen the interaction between teachers and students and to encourage students to master the basic mathematical knowledge in the process of thinking independently and solving problems Learning efficiency. Therefore, this article starts from the following aspects on how to construct a highly efficient math class by means of the creation of problem situations. First, the introduction of mathematics problems in the creation of links into the situation is the first step in a class, but also decided to implement efficient classroom successfully
