BioWorld is a computer-based learning environment that provides a realistic environment for students to learn about diseases through solving specific patient cases (Lajoie, Lavigne, Guerrera, & Munsie, 2001). BioWorld provides a hospital simulation where students learn diagnostic reasoning by visiting patients, interpreting patient symptoms, conducting diagnostic tests, and collecting appropriate information in the library. Solving a patient case in BioWorld not only consists of submitting the right diagnosis, but also requires the student to select and organize evidence that supports and justifies decisions made throughout the case resolution process. Interface of the BioWorld System


One key aspect of adapting BioWorld to a medical audience is to revise and construct cases at an appropriate level. In our attempts to create and develop valid cases in medical education, we have experimented with different methodologies and scenarios to structure case creation (Gauthier, Lajoie, Richard, & Wiseman,2007). The companion authoring tool, CaseBuider (Lajoie et al., 2001) was designed to allow both instructors and researchers to easily modify cases and also enable to explore instructional activities for case creation. A newly built web-based management interface allows instructors to manage student users, selectively release cases, and review dynamically-generated individual and class reports.
