Abstract

In this paper we express a concern that there is a treasury of \advanced" mathematical ideas and experiences that are natural and accessible to children in grades K-4, and yet appear nowhere in the standard contents of the mathematics curriculum for these grades, including the NCTM Standards. We argue: (1) that Standards 1-4 (mathematical reasoning, problem solving, communication and making connections) are the most signiicant of the NCTM Standards and cannot be realized without an expanded mathematics content agenda; (2) that the project of implementing Standards 1-4 is intrinsically connected to the issue of mathematical science popularization, and is well-served by approaches that include manipulative, experiential, and open-ended topics based on deep mathematics; (3) that literature and literacy provide useful and powerful metaphors for understanding the important issues in mathematics education reform. In the project of enriching the mathematics content agenda for grades K-4 there is an especially important role for the wealth of concrete topics and mathematical models of modern discrete mathematics and computer science.

落实标准:抓好“前四”
在本文中,我们表达了一种担忧,即K-4年级的儿童自然可以获得的“高级”数学思想和经验的宝库,但在这些年级的数学课程的标准内容中却没有出现,包括NCTM标准。我们认为:(1)标准1-4(数学推理,解决问题,沟通和建立联系)是NCTM标准中最重要的,如果没有扩展的数学内容议程,就无法实现;(2)标准1-4的实施项目与数学科普问题有着内在的联系,并且采用了基于深度数学的操作式、体验式和开放式的方法;(3)文学和读写能力为理解数学教育改革中的重要问题提供了有用而有力的隐喻。在丰富K-4年级数学内容议程的项目中,丰富的现代离散数学和计算机科学的具体主题和数学模型具有特别重要的作用。
