Data analysis can provide a powerful and relevant approach to teaching key mathematical skills to elementary school children. It provides a meaningful context for the use of computation skills. It involves students directly with important mathematical ideas that are applicable to science, social science, and problem solving. It is a vehicle for bringing real applications of mathematics into the classroom. It is a topic that is familiar to teachers. And calculators and computers provide tools for collecting and analyzing data in the classroom that previously have not been available. This project will develop recommendations, prototype materials, and calculator and computer activities to be infused into a new K-6 curriculum strand on data analysis. The materials will emphasize age- appropriate data analysis skills such as counting, comparing, classifying, looking for patterns, finding central tendencies and variation, and predicting trends. This project will target a broad range of students, especially those who have historically been underserved (girls, minorities, and disadvantaged students). Project materials will reach approximately 10,000 teachers through a network that will distribute a newsletter as well as the student materials. Videotapes will be produced for use in teacher education.

数据分析可以为教学提供一种强大而相关的方法 小学生的关键数学技能。 它提供了一个 对使用计算技能有意义的上下文。 它涉及 学生直接与重要的数学思想是适用的 to science科学，social社会science科学，and problem问题solving解决. 它是一种交通工具， 将数学的真实的应用带入课堂。 这是一个 这是老师们熟悉的话题。 还有计算器和电脑 提供在课堂上收集和分析数据的工具， 以前是没有的。 该项目将制定建议、原型材料， 计算器和计算机活动将被注入到一个新的K-6 数据分析课程。 材料会强调年龄- 适当的数据分析技能，如计数，比较， 分类，寻找模式，发现中心趋势， 变化和预测趋势。 该项目将针对广泛的学生，特别是那些 在历史上一直得不到充分的服务（女孩、少数民族和弱势群体 学生）。 项目材料将提供给大约10 000名教师 通过一个网络，将分发一份通讯，以及 学生材料。 将制作录像带供教师使用 教育
