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

9819107 . cannon这个教学材料开发领域的项目将为K-8级的数学开发一个独特的交互式网络虚拟操作库。这些材料大部分将以Java applet的形式提供，并且将免费提供（通过internet）。它们还将成为全国数学教师委员会《学校数学原则和标准》电子格式版的组成部分，并与其他可能的传播途径联系起来。虽然这些材料是针对儿童的，但它们也将对学前和在职K-8教师的数学背景有用。共同负责人认为，虚拟教具将促进儿童更好地理解重要的数学概念，并与教师的内容理解需求联系起来。此外，根据上述传播计划，项目材料将从两个网站中的任何一个网站提供，供联机使用或免费下载到当地网络或通过CD-ROM提供。

9819107CANNONThis project in the area of Instructional Materials Development will develop a library of uniquely interactive web-based virtual manipulatives for mathematics in levels K-8. 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.
