This project seeks to extend the work already being done (with NSF funding) on a web-based library of virtual manipulatives for students in grades K-8. Materials will be developed serving grades 9-12. Other features to be added would be translation into Spanish and voice-overs for existing materials, and the capability of printing and saving student work. A set of software tools for teachers would enable them to construct customized web pages using the manipulatives, as well as small modules ready for insertion into existing curricula. New materials developed for teachers will include lists of instructional objectives, suggested learning activities and assessment tools. Evaluation will investigate the quality of human/computer interaction, the relevance of the materials to current pedagogy, the effectiveness of the resulting instruction and the process of building communities of users of the materials. Questions to be asked in evaluation include: Does the project increase student access to the potential of the computer? Does it increase the perceived relevance of the mathematics to the student? Will it increase collaboration between on-line users? Quasi-experimental studies, observations interviews, and surveys will be used to answer these questions. Dissemination will proceed through commercial publishers who have already committed to this project, through the Web, and through professional journals and conferences.

这个项目寻求扩展已经完成的工作(由美国国家科学基金会资助)，为K-8年级的学生建立一个基于网络的虚拟操纵库。材料将为9-12级开发。其他将增加的功能包括将现有材料翻译成西班牙语和画外音，以及打印和保存学生作业的能力。一套供教师使用的软件工具将使他们能够使用操纵器构建定制的网页，以及准备插入现有课程的小模块。为教师编写的新教材将包括教学目标、建议的学习活动和评估工具的清单。评价将调查人机交互的质量、材料与当前教学方法的相关性、所产生的教学效果以及建立材料使用者社区的过程。评估中要问的问题包括：该项目是否增加了学生接触计算机潜力的机会？它是否增加了学生对数学的感知相关性？它会增加在线用户之间的协作吗？准实验研究、观察访谈和调查将被用来回答这些问题。传播将通过已经致力于这一项目的商业出版商、网络以及专业期刊和会议进行。
