    Arnold H. Packer is a senior fellow at the Institute for Policy Studies at Johns Hopkins University and recently served as executive director of the U.S. Labor Department Secretary's Commission on Achieving Necessary Skills (SCANS). He is currently chair of the SCANS/2000 Center. Dr. Packer has extensive experience in the fields of restructuring U.S. education and policymaking and is co-author of Workforce 2000, a publication that has influenced the national conversation about human resource education. He has worked extensively with distinguished representatives from business, labor, education, and government to define the skills needed by all high school graduates to succeed in the workplace. Dr. Packer previously served as the assistant secretary for Policy, Evaluation, and Research at the U.S. Department of Labor, where he formulated the administration's approach to work-based welfare reform and to retraining workers dislocated by economic change. His most recent book is School-to-Work: Reinventing the Learning Enterprise.

    Andries van Dam is Thomas J. Watson, Jr., University Professor of Technology and Education and professor of computer science at Brown University, and was one of the Computer Science Department's founders and its first chair, from 1979 to 1985. His research has concerned computer graphics, text processing, and hypermedia systems. He has been working for more than 30 years on systems for creating and reading electronic books for use in teaching and research. The current project in this research, Exploratories, addresses the educational challenges implicit in a rapidly changing, Web-based environment. An exploratory is a computer-based combination of an exploratorium and a laboratory that embeds in a hypermedia environment a multifaceted interactive microworld that models objects, phenomena, and concepts. In addition, he has been concerned with teaching object-oriented programming and design, including elementary design patterns, in an introductory computer science course. Professor van Dam received the B.S. degree with honors from Swarthmore College in 1960 and the M.S. and Ph.D. from the University of Pennsylvania in 1963 and 1966, respectively. He co-founded ACM SIGGRAPH, has been on the editorial board and served as editor of several computer graphics journals, and is on the technical advisory board of several startups and of Microsoft Research.
