Many schools have an expressed an interest in using the Internet as a vehicle to conduct problem-based learning (PBL), although opinions regarding the criteria for online PBL are as varied as methods of its standard implementation.  However, all agree that the Intranet has brought numerous options for enhancing the original precepts of this form of learning. 

At the University of Colorado we have developed a system which employs a CD-ROM/Web hybrid program.  This met our need to provide guided design digital video cases to students at remote clinical sites which serve as a stimulus for learning with asynchronous case discussions.  Designated as Project L.I.V.E., this series of cases features progressive disclosure with digital video of patient/physician encounters from a CD-ROM.  Links take students to a form in which they enter what they know about the case, their hypotheses, and their learning issues.  Groups of 4-5 students and a faculty facilitator discuss the case, teaching each other within the discussion section.  This blend of technologies requires students to work through the case both individually and collaboratively.
