“创设情境”是数学课堂中一道亮丽的风景线。《数学课程标准》在实施建议中明确指出,数学教学要紧密联系学生的生活实际,从学生的生活经验和已有知识出发,创设各种情境,为学生提供有利于数学学习的课堂环境。为了构建生动活泼、富有个性的数学课堂,许多教师把创设情境、激发学生的学习兴趣当成数学教学的重头戏,有些教师为了片面追求教学情境,淡化甚至扭曲了情境教学的初衷,降低了数学教学的实效。究竟如何来创设数学课堂的有效 “Create situation ” is a beautiful landscape in mathematics classroom. In the implementation of the “Mathematics Curriculum Standards” clearly pointed out that mathematics teaching should be closely linked with the students ’actual life, starting from the students’ life experience and existing knowledge, to create a variety of situations, to provide students with a classroom environment conducive to mathematics learning. In order to build a lively and personalized mathematics classroom, many teachers regard creating situations and stimulating students’ interest in learning as the highlight of mathematics teaching. Some teachers, in order to unilaterally pursue teaching situations, dilute or even distort the original intention of situational teaching, Effective. How to create an effective mathematical classroom
