Children's Construction of uncertainty, chance and causality: Making sense of patterns and variability in data

该项目的重点是发展儿童对数据模式和可变性的解释;以及他们对这一过程中涉及的关键概念，不确定性，机会和因果关系的阐述。 孩子们解释的数据是他们自己在科学调查中收集的数据。 从若干角度来看，这一重点具有战略意义。 将数学教育实践转化为一个更加面向概念和应用的领域，符合NCTM的关注。 更具体地说，它符合NCTM建议教师如何在低年级开始开始非正式的统计和概率研究：让孩子们参与数据收集，数据表示和数据解释，以及他们对机会概念的探索。 这一研究议程同时解决了科学教育这一领域日益增长的关注，即尽可能考虑到发展的限制，儿童的科学教学应符合科学探究的性质雅阁。

This project focuses on the development of children's interpretations of patterns and variability in data; and their elaboration of key concepts involved in this process, uncertainty, chance, and causality. The data the children interpret are data they themselves have collected in the context of investigations in science. this focus is strategic from a number of perspectives. It accords with the NCTM's concerns to transform the practice of mathematics education into a more concept-oriented and applied domain. More specifically, it fits with how the NCTM recommends teachers begin informal study of statistics and probability in the early grades: engaging children in data collection, data representation, and data interpretation, in conjunction with their exploration of concepts of chance. This research agenda simultaneously addresses a growing concern within this field of science education that, as far as possible given developmental constraints, children's science instruction should accord with the nature of scientific inquiry.
