The project, operated as a collaborative grant between the University of Oregon and the University of Arizona, is developing interactive experiments and delivering them over the Internet. Most of these experiments are executed using the JAVA programming language extension to HTML document structure. Others use the VRML extension to HTML, which allows 3D representations of complex spatial relationships. These tools will be integrated into a fully-featured World Wide Web site which will act as a virtual classroom for about 5400 students per year at the University of Oregon and the University of Arizona. The Web site will have an electronic textbook, research databases, supercomputer simulations, and animations. There is a critical need to engage introductory science students in an experimentation mode that will lead to student-driven inquiry. This project aims (1) to allow students to use active experimentation to learn abstract topics, (2) to incorporate scientifically realistic modes of inquiry into instructional technology, (3) to build a library of experiments that is adaptable to any curriculum, and (4) to construct a Web site that can be customized for use by any instructor. Instructional technology can be a very cost-effective means of achieving our main pedagogical goal: teaching science as a discovery process that relies heavily on experimental results, not memorized facts and figures. The project also has distance education dimensions, involves the cooperation of institutions for curriculum development, and uses emerging technologies to engage the students in this new learning mode. The potential audience for these tools extends to the 500,000 physics and astronomy students at two and four year colleges nationwide and more students at the high school level. The work builds on an already highly successful implementation of hypertext based course material, in which professional data, scientific animation, and links to other resources are all organized into a network textbook that beco mes the lecture and learning tool that students see in class and access out of class. Building more interactivity into this curriculum is both the next logical and most critical step.

该项目由俄勒冈大学和亚利桑那大学合作资助，正在开发交互式实验，并通过互联网发布。这些实验大多是使用JAVA编程语言扩展到HTML文档结构来执行的。其他人则使用HTML的VRML扩展，它允许复杂空间关系的3D表示。这些工具将被整合到一个功能齐全的万维网网站中，该网站将作为俄勒冈大学和亚利桑那大学每年约5400名学生的虚拟教室。该网站将有电子教科书、研究数据库、超级计算机模拟和动画。我们迫切需要让理科入门学生参与实验模式，这将导致学生驱动的探究。这个计划的目的是(1)让学生通过积极的实验来学习抽象的主题，(2)将科学现实的探究模式融入到教学技术中，(3)建立一个适用于任何课程的实验库，(4)构建一个可供任何教师定制使用的网站。教学技术是实现我们主要教学目标的一种非常经济有效的手段：将科学教学作为一个发现的过程，在很大程度上依赖于实验结果，而不是死记硬背的事实和数字。该项目还具有远程教育维度，涉及机构合作开发课程，并使用新兴技术使学生参与这种新的学习模式。这些工具的潜在受众扩展到全国两年制和四年制大学的50万名物理和天文学学生以及更多的高中学生。这项工作建立在一个已经非常成功的基于超文本的课程材料的基础上，其中专业数据、科学动画和其他资源的链接都被组织到一个网络教科书中，成为学生在课堂上看到和在课堂外访问的讲座和学习工具。在这门课程中建立更多的互动性是下一个合乎逻辑也是最关键的步骤。
