CAL is the University of Pennsylvania School of Veterinary Medicine's Computer Aided Learning program. CAL projects are designed to supplement the veterinary curriculum offered by the School and provide the students with an alternative to traditional lectures. By providing the projects via the WWW, students may review the projects as often as they want. The graphics, video clips, case study formats, and the interactive nature of the projects help to actively engage the student in the learning process.
