  • The Future of Distance Learning Technology in Rural Missouri J. Scott Christianson, Owner Kaleidoscope Consulting Lessons From Ten Years of I-TV
    • In 1989-90, the University of Missouri established videoconferencing facilities and links between UMSL, UMKC, and UMC.
    • In 1993, a pilot project formed three K-12 networks in the state. Funding was provided by local telephone companies.
    History of I-TV in Missouri
  • WeMET
    • Dedicated T1 Network
    • Six high schools
    • Central Missouri State University serves as the higher education partner
    History of I-TV in Missouri
  • MITE Network
    • Dedicated T1 network
    • Five high schools
    • Central Methodist College serves as the higher education partner
    History of I-TV in Missouri
  • EPN Network
    • Analog Fiber Network
    • Four high schools
    • Higher education partner is North Central Missouri College (without direct connect to network)
    History of I-TV in Missouri
  • Results of Pilot Project
    • Two-way Interactive Television proved itself to be a distance learning technology that can accommodate many of the same modes interaction between teachers and students used in the traditional classroom.
    • It can help schools maintain the benefits of small size while expanding opportunities for their students.
    History of I-TV in Missouri
  • Number of K12 Sites From MODLA data I-TV Growth in Missouri
  • Types of Growth
    • New Clusters
    • Additions to existing network/clusters, a case in point is the MIT-E Network:
      • MIT-E Central added in 1999 (5 schools)
      • MIT-E South added in 2000 (4 schools)
      • Addition of three more schools to South and Central in 2001
    • Schools that are independent of clusters. These typically connect via H.323 over existing MOREnet connection.
    I-TV Growth in Missouri
  • I-TV Technologies TIME H.323 H.320 Dedicated T1 ATM Analog Fiber DS3-J Series DS3-M Series POTS IsoEthernet H.322 H.310 H.321 ISDN I-TV Growth in Missouri
  • Videoconferencing Standards
    • H. 323 is, in many ways, still developing. The basis for voice over IP telephony, it’s reach is rapidly expanding and it is widely supported by WANs.
    • H.320 is the tried and true standard for videoconferencing, having been perfected over the years. While it is on the way out, it is reliable and predictable. Don’t expect to see many new features added to this standard.
