Presentation Transcript

  1. Digital Information and Communication Peters Chapter 6

  2. Unparalleled Change • Development of the PC • Improvement of telecommunications • Development of multimedia technology • Development of larger and more extensive databases connected to Internet

  3. An Optimistic Assessment • Convergence of media • Computer as a multimedia communications device • Audio and video conferencing on the desktop

  4. Widen Communication Channels • Distance turns into virtual proximity • Writing can be replaced with oral • Inclusion of live voice of teacher and learner • Rich dialog

  5. A Realistic Interpretation • Presence of media does not guarantee use • Hype does not translate into practice • Obstacles include: • Money • Practice • Institutional custom

  6. First Pedagogical Analyses

  7. Learning with files • The ability to create and extend personal files of knowledge • This potential for self-learning can only be speculated at (growing hypertexts)

  8. Hypermedia • Changing teaching behavior • Must teach on many levels • Break text into nodes • Great promise for addressing students in a multi-modal way • Difficult to create

  9. Hypermedia • Changing learning behavior • Granted more freedom • Must find their way through hypertext • Strategies dealing with implicit and explicit linking. Three possible ways: • Browsing • Searching for defined information • Following a teacher-defined path

  10. Knowledge-building Community • Bootstrapping knowledge creation through shared contributions • All have role as learner and teacher • Is constructivist, autonomous, collaborative, authentic

  11. Teaching Programs • CAI - known strengths and weaknesses

  12. Learning with data-file courses • From print to new media • Is the medium the message, or is there no difference between delivery? • Richer opportunities in new media

  13. Computer Conferencing • Dominance of text is “absurd”

  14. Computer Conferencing • Advantages • Detailed record of class proceedings • Students consider replies more deeply • Virtual tutorial space • Peer discussion predominate • Lessens isolation • Even some emotional and social bonds that are uniquely strong

  15. Computer Conferencing • Disadvantages • Less spontaneous • Some students tend to dominate • Students can drop out and not be missed • Can be overwhelmed by data if not logged in for a while • If not well moderated, can degenerate to "small-talk"

  16. Audio- and Video-Conferencing • What innovations do these bring? Garrison • Essence of learning and teaching is communications • Dependent on quality of communication • Are able to [re]capture all classroom techniques • Many strive to recreate the university classroom in these media

  17. Audio- and Video-Conferencing • Four types of teleconferencing • Two-way audio • Two-way audiograhics (adds graphics to communications line) • One-way video and two-way audio • Two-way video and two-way audio • All improved by great bandwidth and computer enhancement

  18. Audio- and Video-Conferencing • Have created an explosion of learning

  19. Audio- and Video-Conferencing • American model • Extended university classroom • Always interactive and in real time • Requires the least change of instructors • 'Face to face teaching at a distance’

  20. Audio- and Video-Conferencing • Ways to get beyond this conservative model • Mixed mode with only some class functions in teleconference • Partial use as extension of classes • Search for other pedagogic models • Concludes that use intimating classroom is transitory

  21. Commentary on VC • Does this represent the future of distance education? • NO! • American videoconferencing is NOT distance education • Americans are concerned with 'access', Europeans with pedagogy

  22. Autonomous Learning • This is the ultimate goal of education • Reality cannot be taught, but must be constructed by an autonomous learner • Argues that learning is simple a process of individual searching and constructing

  23. Autonomous Learning • Tight leash or more autonomy? • Computer • Storage frees student memory • Provides access to large quantities of information • Create independent assessment • Create personal knowledge structures • Graphical representations

  24. Summary • Learners become researchers and designers

  25. Integrated Presentation • Escape from tyranny of text to orality • Motion pictures and animation • Accounts for television and new sense balances • DE practitioner must provide multi-modal environment

  26. Occasional & Transversal Learning • Just-in-time learning • Trans-discipline learning • Embedded in life • Non-sequential, but determined by need

  27. End Return to Agenda
