We envision CD-ROM cases, to become available in mid-1995, meeting a wide array of professional needs. First, the CD cases should enhance teacher preparation. For example, class discussions may be augmented by students' prior viewing of a case. Recently, masters level students suggested that they use the CD ROM to prepare for class to gain a far richer understanding of the issues prior to the case discussion. After class, students working alone or in groups can continue to explore the case and its resources. Throughout the process, the on-line notebook tools that document the students' questions and reflections may provide creative opportunities for innovative assessments of students' progress.

Curriculum for distance learning is avenue for using CD-ROM case materials. The instructor can conduct the case discussion via interactive video, simulating the immediacy of a classroom. CD materials might also be shared electronically via multi- user shared environments (MUSE), networked computers that would enable case viewers at physically separate locations to share screens and work simultaneously on the same case. Again, proximity is created through the CD even though the participants may be at considerable distance from one another.

The compact discs can be used as part of ongoing professional development for experienced teachers. The program's e-mail and internet video conferencing tools will link experienced teachers at diverse geographic locations. They can discuss issues raised in the case that are pertinent to their implementation of reform. Beginning teachers can also interact with experienced teachers throughout the state or nationally. Mentoring activities are now possible on a immediate basis. These collaborative activities underscore how even a self-contained CD ROM can preserve the key feature of the case method: Intense participation in the discussion of professional dilemmas and pedagogical issues.
