IDEA: Internet Differential Equations Activities

国家科学基金会资助的IDEA项目已成功地通过因特网向世界各地的学生及其教师提供了微分方程教材。它包括课堂练习，Java小程序来说明微分方程的原理，Java代码生成工具，和基于Microsoft Windows的微分方程求解软件。目前的项目旨在扩大和深化民主选举所的范围。它将提供额外的软件来解决边界值问题和偏微分方程，并以图形方式说明解决方案。该项目将包括从数学、化学、农业和经济学等不同领域继续开发额外的练习。此外，还将努力评估与该项目有关的现实问题和技术工具在课堂上的有用性。

The NSF-funded IDEA project has successfully delivered differential equations in instructional materials over the Internet to students and their instructors throughout the world. It encompasses classroom exercises, Java applets to illustrate principles of differential equations, Java code generation facilities, and Microsoft Windows based differential equations solving software. The current project is intended to broaden and deepen the scope of IDEA. It will provide for additional software to solve boundary value problems and partial differential equations, and to illustrate the solutions graphically. The project will include continued development of additional exercises from fields as diverse as mathematics, chemistry, agriculture, and economics. In addition, there will be an effort to evaluate the usefulness of the realistic problems and technological tools associated with the project in the classroom.
