Technology Transitions Mathematical Modules for Preservice Teachers

该项目旨在满足K-12数学教师有效使用技术和透彻理解数学概念的需要。然而，为职前教师提供的典型的数学方法或内容课程，几乎没有提供以连贯和统一的方式解决这两个问题的机会。在这个项目中，正在开发一个用于数学的“过渡模块”资料库，并为从幼儿到中学的职前教师开设教学课程。每个过渡模块专注于一个单一的数学概念，使用多种不同的技术引导学生完成一系列调查。因此，术语技术指的是做数学或教数学的任何工具，包括机械手、纸和铅笔、计算器、计算机和互联网。这些活动培养了比较和对比不同技术在数学学习和教学中的使用的经验。它们还通过使用应用于同一问题的多种技术来促进更好的数学理解。一旦开发，过渡单元将按课程分组成实验室手册，并通过万维网在全国范围内传播。商业出版也可以通过传统的书籍形式或CD-ROM来实现。目前正在执行一项全面评价计划，以衡量单元对教与学的影响。

This project addresses the need for K-12 teachers of mathematics to use technology effectively and to have a thorough understanding of mathematical concepts. The typical mathematics methods or content course for preservice teachers, however, offers few opportunities to address both of these issues in a coherent and unified manner. In this project, a library of "transitions modules" for use in mathematics and content courses for preservice teachers ranging from the early childhood to the secondary level are being developed. Focusing on a single mathematical concept, each transitions module leads the student through a series of investigations using a number of different technologies. Hence, the term technology refers to any tool for doing or teaching mathematics, including manipulatives, paper and pencil, calculators, computers, and the Internet. These activities foster experiences in comparing and contrasting the uses of different technologies in learning and teaching mathematics. They also promote better mathematical understanding through the use of multiple technologies applied to the same problem. Once developed, the transitions modules are being grouped by courses into laboratory manuals and disseminated nationally via the World Wide Web. Commercial publication is also envisioned in either traditional book form or on a CD-ROM. A comprehensive evaluation plan is being implemented in order to measure the effects of the modules on teaching and learning.
