Distance Learning Tech: First and Second Generations
• First Gen: Mainly utilized written and printed texts incl. books, manuals,
research papers etc.
• In First Gen, student evaluation was typically summative and was usually done at mid- and end- of the course. This emulated the classroom teaching for those who could not regularly attend classes, but with only limited interaction between students and teachers.
• Second Gen: Initially started with radio, TV as instructional media. But gradually incorporated interactive multimedia learning materials in CD-ROM as well as on web.
• Second Gen subsequently adopted ICT to provide interaction in addition to
content delivery. Tele-learning model subtleties have been discussed at length in this slideset [see later]. Author’s earlier work in Hughes has been presented in Pacific Telecom Council India Foundation (PTCIF) Annual Conference,
New Delhi, Feb. 2003 as Invited Speaker). [Cover & Inside Photo: Univ. of Chicago, Next Page Photo: MIT and Harvard who pioneered edX Program]

Distance Learning Tech: Third Generation with MOOC
• Third Gen: Flexible Learning model got introduced based on online delivery via internet. Subsequently this is made intelligent by making learning interactive. Personalization of content made possible based on learner’s learning preference.
• Massive Open Online Course (MOOC) aims at unlimited participation and open access via web. 2012 became “the year of MOOC” with Coursera, Udacity, edX services. Along with top university-supported such platforms, also came other e-learning platforms such as Khan Academy, P2PU, Udemy and others.
• The author serving as member of Corporate Advisory Board in edX since 2016. EdX marks a 73% growth in India in one year – IndiaInfoline

Need for Broadband Networks
– Audio-conferencing
– Video-conferencing
– E-learning---Transformative application
area dependent on emergence of
ubiquitous, low-cost, high-bandwidth
networks
– “Next Internet” for Multimedia learning

Canadian Experience of Tele-learning
– 2000: 60% of colleges, univ offered more
than 3000 on-line courses
– Alliances and consortium arrangements
– First country to connect all its K-12
schools and libraries to internet
– Many courses with low bandwidth
requirements; but barely scratch e-
learning potential
