Emerging technologies are allowing new and innovative applications of teaching cases. Videotape can be useful in capturing actual events, or realistically simulated events, to serve as the basis for a case, and supporting text materials can guide both teachers and learners in the use of such cases in instructional settings. CD-ROM technology has been used in several instances to overcome limitations inherent in the linear format of video by making it easier for users to interact with the case and supporting instructional materials. The Internet and telecommunication technologies have also provided new vehicles for delivering cases to learners. Because of its ability to transmit text, graphics, sound, and short movies, the World Wide Web offers substantial potential for the development and presentation of case materials.
MOOs present another interesting medium for case use.
However, MOOs are much more than real-time chat. MOO environments are populated with text-based descriptions of objects that can be manipulated. A virtual letter can be read as well. As such, virtual rooms, objects and exhibits are programmed for people to interact with. MOOs also allow individuals to assume different identities with ease and allow geographically separated individuals to collaborate in a common setting.
