Calculus on the Web

在过去的两年中，主要研究人员开发并实施了网络微积分（COW），这是一个基于互联网的交互式模块化学习系统，用于微积分的研究，包括基本技能和技术的实践，以及对基本概念的“动手”实验。注册用户或匿名访问者都可以免费访问COW环境。本项目将通过以下方式完成《微积分教程》环境：1)创建新的模块结构，使《微积分教程》成为完整的在线教材；(2)进一步发展COW的逻辑、句法和数学分析及其用户交互的“智能”和“人性化”特征。环境测试涉及各种机构，包括中学部分。证据还表明，这种特殊的网络环境有助于女学生以高水平的兴趣参与微积分主题。

Mathematical Sciences (21) Over the last two years, the principal investigators have developed and implemented Calculus on the Web (COW) - an interactive Internet-based modular learning system for the study of calculus, including practice of basic skills and techniques, and "hands-on" experimentation with basic concepts. The COW environment is freely accessible to either registered users or anonymous visitors. This project is completing the COW environment to address a full three-semester sequence in basic calculus by: (1) creating new module structures that broaden and diversify the COW as a complete, on-line textbook; and, (2), further developing the "intelligence" and "human" character of COW's logical, syntactical and mathematical analysis and of its user interactions. Testing of the environment involves a variety of institutions and includes a secondary school component. Evidence also suggests that this particular online environment helps women students engage with the subject of calculus at a high level of interest.
