The investigators are implementing Calculus on the Web (COW), an interactive electronic learning system for basic mathematics. It is accessible through the internet from any platform capable of running a standard web browser, at http://cartan.math.temple.edu/~cow/. The system presents in modular form units for study, practice and "hands-on" experimentation for each of the great variety of topics in a number of courses. Some key features of COW which distinguish it from the current generation of mathematics learning software are: (i) the system is not a canned, multiple choice question environment, but requires the student to compute and enter a numerical or mathematical expression; (ii) the system algebraically analyzes answers and has the flexibility to detect partially correct responses and create individually tailored replies. For the current project, the system will be developed for a complete treatment of calculus, for precalculus and linear algebra. The educational objectives of COW are: 1. To create an interactive platform for mathematics skill development and intellectual exploration without the overhead of supervision and technical training of students in specialized software. 2. To provide an on-line version of assigned, graded homework, particularly useful for large or multi-section courses without graders. 3. To offer the electronic equivalent of mathematics tutoring, at home or any campus workstation. 4. To make the system available for all calculus classes at local high schools, and to all other US universities that wish to use it. 5. To do all this with a low maintenance, simple-to-use system exploiting existing university facilities and internet technology.

研究人员正在实施网络微积分（COW），这是一个基础数学的交互式电子学习系统。它可以通过互联网从任何能够运行标准Web浏览器的平台访问，网址为http://cartan.math.temple.edu/~cow/。该系统以模块化的形式为许多课程中各种各样的主题提供学习、实践和“动手”实验的单元。COW区别于当前一代数学学习软件的一些关键特征是：（i）该系统不是一个罐头，多项选择题环境，但要求学生计算和输入数值或数学表达式;（ii）该系统代数分析答案，并具有检测部分正确答案的灵活性，并创建个性化的答案。对于目前的项目，该系统将开发一个完整的治疗微积分，为precalculus和线性代数。 COW的教育目标是：1。为数学技能发展和智力探索创建一个互动平台，而无需对学生进行专业软件的监督和技术培训。2.提供在线形式的指定、评分作业，特别适用于没有评分员的大型或多部分课程。3.在家里或任何校园工作站提供数学辅导的电子等价物。4.使该系统可用于当地高中的所有微积分课程，以及所有其他希望使用它的美国大学。利用现有的大学设施和互联网技术，通过低维护，简单易用的系统来实现这一切。
