Hands On Data: Direct--Manipulation Environments for Data Organization and Analysis

当前课程思想的趋势反映了这样一种认识， 使用真实世界的数据可以增加丰富性，相关性和 具体到数学和科学的研究。 但 学生在数据组织和数据方面的能力目前很差 分析表明，我们需要帮助学生发展 数据建模的技能和概念-即设计，收集， 组织、解释和评论数据。 新的计算技术使一类高度可视化， 用于处理“属性数据”的高度交互式工具， 数据库程序目前用于的重要数据类别 主要可用工具。 这些新工具可以（1）描绘差异 （2）让学生互动 更直接地与数据嵌入的结构相关联;以及（3） 把前所未有的分析能力在所有学生的处置 年龄 这个项目追求这样的工具可以支持的猜想 学生学习数据建模的概念，开拓新的 发展面向世界、以探究为基础的 数学和科学课程，这是现在很多人提倡的。 本项目将（1）确定与数据有关的概念挑战 建模，（2）开发和测试软件设施和教学 针对这些挑战采取的措施。 研究和形成 评估将在临床环境中进行，主要是在 中学水平，但对年轻人和老年人有所关注 学生

Current trends in curricular thinking reflect the recognition that working with real-world data can add richness, relevance and concreteness to the study of mathematics and the sciences. However, the current poor state of student abilities in data organization and data analysis suggests that we need ways of helping students develop the skills and concepts of data modelling -- that is, designing, collecting, organizing, interpreting and critiquing data. New computing technologies make possible a class of highly visual, highly interactive tools for working with "attribute data, " an important class of data for which database programs are currently the primary available tool. These new tools can (1) portray differences among categorical, ordinal and numerical data; (2) let students interact more direcly with the structures in which the data are embedded; and (3) put unprecedented analytical power at the disposal of students of all ages. This project pursues the conjecture that such tools can support students' learning of data modelling concepts and open up new opportunitites for the development of world-situated, inquiry-based curricula of mathematics and science which so many are noow advocating. This project will (1) identify conceptual challenges relating to data modelling, and (2) develop and test software facilities and pedagogical approaches targeted to these challenges. Research and formative evaluation will be carried ouot in clinical settings, primarily at the middle school level but with some attention to younger and older students.
