CD-MANIC the best of both worlds
  • CDs
  • for bandwidth intensive content
  • internet for
  • content updates
  • logging student behavior
  • collaboration
  • search
  • external links
  • overcomes any bandwidth constraints provides
    convenience
  • contents dont change often
  • use anywhere
  • planes, trains, behind firewalls

Multimedia Virtual Classroom
  • Automatic data collection and indexing
  • Audio/video
  • PPT, handwriting
  • online materials, etc
  • Collaborative Learning Environment (CLE)
  • Active
  • Coversational
  • Constructive reflective
  • Intentional contextual

10
MVC as an active CLE
  • active
  • Goal active interface, navigation
  • base index, simple search
  • extended search, active objects (text,
    images)
  • learner-controlled interface

11
MVC as an conversational CLE
  • conversational
  • goal support collaboration
  • base threaded discussions
  • CLIMANIC

12
MVC as a constructive reflective CLE
  • constructive reflective
  • goal notation, collaboration
  • base none
  • notes on slides, threaded discussions, save
    CLIMANIC collaborations, integrated reporting

13
MVC as an intentional contextual CLE
  • intentional complex contextual
  • goal problem-focused pedagogy active classroom
    strategy, realistic problem domains
  • base problem-focused learning
  • CASA, on-campus distance learning
    integration, design tools environment

MVC supporting learner logger
  • important tool for assessment
  • goal assessing individual and course learning
    goals
  • base quizzer, logger
  • integrate with new tools extended search,
    notation, collaboration
  • extend to integrated design tools environment
  • integrate with CMS (OWL, WebCT, Blackboard)

CCNY Virtualized Classroom
  • Automated MM data capture
  • Sensing, synchronization and recording
  • Intelligent MM data integration
  • Video, PPT slides, Mimio handwriting pages
  • Flexible User Interface
  • Course adaptive, user customized
  • Virtualized Classroom (VC)
  • A new e-learning environment generated and
    enhanced from materials captured from real

22
VC Media Integration (1)
  • PPT_at_ Slide Mimio page registration

Question What if one of the devices move?
23
VC Media Integration (1)
  • Dynamic registration of PPT_at_ Slide Mimio page
    because
  • Hard to mark in some cases
  • due to occlusion and height
  • Instructor may forget to do it
  • Devices may not be able to keep stationary
  • Camera, projector, Mimio capture bar
  • completely automatic and mind-free approach
