This document, which is designed for classroom teachers at all levels, examines the various electronic communications technologies available today and describes teaching methods and classroom techniques that teachers of business communication and other business education courses can use to introduce students to those technologies. Presented first are a brief introduction to available electronic communication technologies and their relevance to business students and a framework for organizing and selecting the best electronic communication tools for given tasks/settings. Next, available electronic communication tools are grouped as follows (based on the communications settings in which they have been deemed most appropriate): same time/same place tools (electronic meeting systems and presentation tools); same time/different place tools (online conferencing/chat, whiteboard conferencing, and videoconferencing); different time/same place tools (work group computing, word processing/electronic document publishing, bulletin board systems/Usenet newsgroups, and kiosks); and different time/different place tools (electronic mail/listservs and hypermedia/multimedia). After a description of the characteristics, applications, and benefits of each electronic communication tool, ideas for using the tool in business communication and other business classrooms are suggested. Concluding the document are a brief look at the future of electronic communication, glossary, and 38 references. (MN)
