摘　　要：本文以美国教育百科出版社出版的供美国5～8年级书生使用的数学教材《情景数学》(Mathematics in Context)中的计算单元为载体通过该教材对因数和除数、平方数、实数的处理,从内容、编排以及习题上比较分析了该教材如何借助丰富生动的情景引导学生一步一步从现实世界走进抽象世界的过程,本文通过该教材与中国教材的比较探讨了研究该教材的意义,得出了包含信息量大、问题串式教学等看法.本文的内容对我国正在进行中的数学课程教材改革有着重要的参考价值.According to the American Encyclopedia Britannica Educational Corporation for the United States 5～8 grade student using a mathematical textbook Mathematics in Context which belongs to the computation unit as the carrier through the materials to the factor and the divisor,square number,real number processing,from the content,layout and exercises on the comparative analysis of the textbook how to use rich and vivid scenes to guide students step by step from the real world into the Abstract world process,through the teaching material and Chinese teaching material comparison study of the textbook,that contains a large amount of information,questions string type.The content of this article is carrying on in our country mathematics curriculum in the reform of teaching materials has important reference value.
