Creating a National Library of Interactive Web-based Virtual Manipulatives for K-8 Mathematics

他在教学材料开发领域的项目将开发一个用于K-8级数学的独特交互的基于网络的虚拟操作库。这些材料大部分将以Java小程序的形式出现，并将(通过互联网)免费提供。它们还将成为全国数学教师理事会《学校数学原理和标准》电子版的组成部分，并与其他可能的传播渠道建立联系。虽然这些材料是为儿童提供的，但它们也将对K-8预科教师和在职教师的数学背景有所帮助。Co-Pi认为虚拟操纵器将促进儿童对重要数学概念的更多理解，并与他们的老师的内容理解需求相联系。此外，根据上文讨论的传播计划，项目材料将可从两个网站中的任何一个网站获得，这些网站可在线使用，或可免费下载到当地网络或通过光盘获得。

The materials will be, for the most part, in the form of Java applets, and will be available free (via the internet). They will also become a component of the electronic format version of the National Council of Teachers of Mathematics' Principles and Standards for School Mathematics as well as link with other possible dissemination avenues. While the materials are for children, they will also be useful for the mathematics background of both pre- and inservice K-8 teachers. The Co-PI's feel that the virtual manipulatives will promote greater understanding of important mathematics concepts for children and link to the content understanding needs of their teachers. In addition, the dissemination plans discussed above, the project materials will be available from either of two web sites to be used on-line or freely downloaded onto local networks or available via CD-ROM.
