Alec M. Bodzin is an Assistant Professor of Science Education in the Department of Education & Human Services at Lehigh University. He received his PhD in Science Education at NC State University. His interest in instructional technology began in the early 1990s with his use of hypermedia applications that interfaced with laserdiscs for instruction in secondary science classrooms. His interests include incorporating telecommunications into science curriculum development and implementation with emphasis on the roles that visual instructional technologies can play in these areas. He is currently involved in the development of a variety of science education multimedia projects, including CD-ROM and World Wide Web technologies as a member of the SERVIT group. 

John C. Park is an Associate Professor of Science Education at NC State University. He came to NC State in 1985 after completing a PhD in Science Education at The Ohio State University. His interest in instructional technology developed from his early 1980s use of the microcomputer for instruction in science. Although his main research effort is in the use of the microcomputer-based laboratory, his interests have expanded to the use of all visual technologies. Dr. Park organized a research group in 1997, Science Education Research in Visual Instructional Technologies (SERVIT). The group's goals include exploring, developing, and researching the use of new instructional technologies in the pre-college science classroom and laboratory.
