  1. Computer Mediated Communications Week 9 LBSC 690 Information Technology

  2. Agenda • Questions • Computer mediated communications • Computer-Supported Cooperative Work • Educational computing • Project presentations

  3. Computer Mediated Communication • CMC refers to human communication via computers--including computer network communication on the Internet and the World Wide Web. People interested in CMC study a range of phenomena--from the dynamics of group communication in Usenet news articles to how people use hypertext to shape meaning. from http://www.ibiblio.org/cmc/center.html

  4. Describing CMC Applications • How many participants? • One or many • When? • Synchronous or asynchronous • Where? • Local or remote

  5. Cooperative systems Inspired by the table in Shneiderman’s “Designing user interfaces”

  6. Asynchronous Remote • Email: centralized storage • Individual • Mailing lists • Usenet: distributed storage • Hierarchical organization • comp.edu.languages.natural • Archive: groups.google.com • Analysis: research.microsoft.com/~masmith/ • Threaded discussion lists • Example: http://discus.hope.edu/f05

  7. Synchronous Remote • Instant Messaging (IM) • e.g., AIM, MSN Messenger • Chat Rooms • Whole lines are sent at a time • e.g., chat.yahoo.com • NetMeeting • IM+audio+video+whiteboard+shared applications • MSN Messenger now includes these capabilities

  8. Glass Wall • Unplanned interactions • Informal communication

  9. Synchronous Local • Meeting support systems • Brainstorming • Online review • Annotated minutes • Example • Teaching theater student tools

  10. Computer SupportedCooperative Work (CSCW) • Work • Grounded in the study of work processes • Cooperative • Assumes a shared objective, task • Technology-supported • Computers are just one type of tools used • “Groupware”

  11. Key Issues in CSCW • Shared information space • Group awareness • Coordination • Concurrency control • Multi-user interfaces • Heterogeneous environments

  12. Case Study: Virtual Reference • Required functions • System architecture • Adoption

  13. Case Study 2:Your Project Team! • Face to face meetings • Teleconferences • Shared workspace on WAM • IM-synchronized work sessions • NetMeeting?

  14. Educational Computing • Computer Assisted Education • What most people think of first • Computer Managed Instruction • What most people really do first! • Computer Mediated Communication • All that CSCW stuff applied to education • Computer-Based Multimedia • Just another filmstrip machine?

  15. Rationales • Pedagogic • Use computers to teach • Vocational • Computer programming is a skill like typing • Social • Computers are a part of the fabric of society • Catalytic • Computers are symbols of progress

  16. Conditions for Success • Most prerequisites are not computer-specific • Need, know-how, time, commitment, leadership, incentives, expectations • The most important barrier is time • Teacher time is by far the most important factor

  17. Alternatives • Facilities • Computer classrooms (e.g., teaching theaters) • Computers IN classrooms (e.g., HBK 2119) • Objectives • “Computer Literacy” • Not so in the Maryland teaching theaters • Comparatively few technology classes

  18. Discussion Point:Computers as Educational Media • What are the most salient characteristics • Books • Video • Computers

  19. Distance Education • Correspondence courses • Focus on dissemination and evaluation • Instructional television • Dissemination, interaction, and evaluation • Computer-Assisted Instruction • Same three functions w/ubiquitous technology
