The geometric increase in computer power and the ubiquitous availability of network connectivity are revolutionizing computing. A computer science curriculum based on old teaching techniques may seem dull and irrelevant to the modern student. Instruction in the undergraduate curriculum for the most part does not make active use of new technology. A multimedia presentation during a lecture by an instructor is considered to be a passive use of technology. In contrast, a student who can control a multimedia visualization is making active use of such technology. The difference between passive and active use of technology is similar to the difference between watching a laboratory demonstration and performing an experiment. Aside from making the learning experience more interesting, a well-designed experiment can challenge the student and encourage creativity. A user-controlled animation can have a similar effect and provide the student with a virtual laboratory environment. A Colleague and I have already successfully redesigned about half of the curriculum for an undergraduate operating systems course by constructing a series of programming projects that enable students to experiment with congruency and communication. This work has been recently published in a book by Prentice Hall and is gaining acceptance at prestigious universities. The remainder of the curriculum in a traditional operating systems course does not easily lend itself to exploration using programming projects that can be completed by a student in a short period of time. I will design a curriculum for this second part of operating systems and for computer networks in which students perform experiments in a virtual laboratory setting. The laboratory experiments will use animated simulations written in the Java language allowing them to be run on virtually any computer connected to the Internet. A framework for developing active animations will be set up so that these animations can be efficiently produced. *

计算机能力的几何增长和网络连接的无处不在正在彻底改变计算。基于旧的教学技术的计算机科学课程对现代学生来说可能显得枯燥乏味。大学课程的教学大部分没有积极利用新技术。讲师在讲座期间进行多媒体演示被认为是对技术的被动使用。相比之下，能够控制多媒体可视化的学生正在积极利用这种技术。被动和主动使用技术之间的区别类似于观看实验室演示和进行实验之间的区别。除了使学习体验更有趣之外，精心设计的实验还可以挑战学生并鼓励创造力。用户控制的动画可以具有类似的效果，并为学生提供虚拟实验室环境。我和一位同事已经成功地重新设计了大约一半的本科操作系统课程，通过构建一系列编程项目，使学生能够实验一致性和通信。这项工作最近已发表在一本书中的普伦蒂斯霍尔和正在获得接受在著名的大学。传统操作系统课程的其余部分不容易使用学生可以在短时间内完成的编程项目进行探索。我将为操作系统的第二部分和计算机网络设计一个课程，让学生在虚拟实验室环境中进行实验。实验室实验将使用Java语言编写的动画模拟，使它们能够在几乎任何连接到互联网的计算机上运行。将建立一个开发活动动画的框架，以便有效地制作这些动画。 *
