  1. Mbone Virtual Classroom Tom Miller Associate Dean for Distance Education & Information Technologies NC State Univ. College of Engineering ALN Conference, Oct 10, 1999

  2. Synchronous Asynchronous Distance Education:Modes of Interaction Same Time Different Place Different Time Different Place Space Same Time Same Place Different Time Same Place Time

  3. NC Engineering Education Partnership

  4. Virtual Classroom Model“It’s all about communication” • Technology serves to facilitate teacher/student and student/student interaction at a distance • Enriched interactive communication through integrated voice, video, and data. • The Web plays a supporting role

  5. Desktop Conferencing “virtual conference room” symmetric peer-oriented continuous presence few-to-few with spontaneous interaction Desktop Classroom “virtual classroom/ auditorium” asymmetric teacher/audience floor control one-to-many with controlled interaction A Different Interaction Model

  6. MBone “Virtual Classroom” • Low cost - desktop computers + Internet • Scalable - IP multicast protocol • Fully integrated voice, video and data • Highly interactive • Classroom cost = ~ $50K • Receiver cost = ~ $2-4K

  7. Teacher Student Student Student Multicast “Class Session” Multicast Session

  9. Real-time Interaction

  10. Shared Whiteboard

  11. Lessons Learned • Technology must be transparent • Audio and whiteboard significantly more important than video in most cases • Continuous presence audio not good for “virtual classroom” • Use electronic “hand raiser” instead • Instructor must be able to point and draw • Synchronous delivery alone not good enough

  12. “DETA” Distance Education Teaching Assistant

  13. Touch-screen “SmartBoard”

  14. Integrated Record & Playback

  15. mMOD - MBone Media on Demand
