Used Numbers: Collecting and Analyzing Real Data

数据分析可以为小学儿童的关键数学技能教学提供一种强大而相关的方法。它为使用计算技能提供了一个有意义的背景。它让学生直接接触到适用于科学、社会科学和解决问题的重要数学思想。它是将数学的实际应用带入课堂的工具。这是教师们所熟悉的话题。计算器和计算机提供了收集和分析课堂数据的工具，这是以前没有的。该项目将开发建议、原型材料、计算器和计算机活动，以融入新的K-6数据分析课程。教材将强调与年龄相适应的数据分析技能，如计数、比较、分类、寻找模式、发现中心趋势和变化，以及预测趋势。该项目将面向广泛的学生，特别是那些历史上服务不足的学生（女孩、少数民族和弱势学生）。项目材料将通过一个网络发给大约1万名教师，该网络将分发一份通讯和学生材料。将制作录像带供教师教育使用。

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.
