Case Study Hall© is an education (and research) tool which incorporates the teaching concepts of problem-based learning and student-centered learning. This occurs through the use of case studies. Users are presented with problems, such as a patient with a list of symptoms. The user searches through the available information in order to diagnose the underlying problems. If a knowledge deficiency is discovered during the process, a user can logoff the system, gather reference material, eliminate the deficiency, then return back to where he/she left off.
