    Internet in the mid-1990s, the notion of a
    knowledge-based society has gained considerable
    acceptance
  • Various trends reflect this emergence
  • Jobs are shifting froma dependency on relatively
    low skills to high skills
  • Major transformations are affecting key sectors
    with the emergence of E-learning, E-commerce,
    E-government E-health
  • Skills knowledge upgrading are becoming a
    continuous requirement associated with on-the-job
    training

The Need for Continuous Learning
  • In the New Economy knowledge is a key resource
    and the quality of a nations work force is
    critical to ensuring competitiveness
  • The key to this transition is for workers to make
    intelligent use of information
  • This capability will increasingly be the measure
    of an individuals contribution to the economy
  • Therefore, life-long learning becomes an
    imperative

10
Emergence of Network-based Education
  • Traditional education is being transformed by the
    enabling capabilities of the Internet, which
    offer
  • new ways of teaching
  • new models of learning
  • means to absorb rapid increase in numbers of
    students
  • means to deliver education/training with
    decreasing numbers of instructors
  • The Internet is globalizing education with the
    emergence of anywhere - anytime E-learning

Future Directions Enabling Technologies
  • Learning Object Repositories
  • Optical Networks
  • Grids
  • Web Services

16
What is a Learning Object Repository (LOR)?
  • A collection of learning objects on a
    distributed network
  • Conforms to certain standards
  • An elegant structure that promotes sharing of
    content without giving up control of curriculum
  • Consistent with emerging Web Services concept

17
What are Learning Objects?
  • Small (or granular) pieces of multimedia (text,
    audio, video, etc.) content that capture specific
    information or concept
  • Learning objects are tagged with metadata in
    standardized ways to ensure consistency,
    accessibility, etc.

18
What is Metadata?
  • Keywords that describe the learning object,
    similar to a library card file
  • Specifications for metadata are being developed
    IMS, SCORM, CanCore
  • International standards will emerge over the next
    few years

19
Why are LORs Important?
  • E-learning content development is expensive and
    time consuming LORs provide a mechanism to
  • share content easily
  • re-purpose content from other sources
  • update content that changes
  • locate desired content quickly
  • control access to appropriate users

20

Summary
  • Learning Object Repositories hold enormous
    promise as effective means for developing,
    storing, retrieving, maintaining, and using
    e-learning content
  • International standards are being developed
  • LORs fit within the context of emerging Web
    Services

27
Future Directions Optical Networks
  • Optical fiber will be the dominate conduit in
    future networks
  • Optical signals multiplexed using wave division
    techniques (i.e., WDM allows for many
    Gigabits/optical strand)
  • LAN technology invading the WAN (e.g., Gigabit
    Ethernet - based on widely known well
    understood principles)
  • Trend towards building your own network using
    dark fiber (e.g., many school districts in
    Québec, Canada)
  • This kind of networking is driving the need for
    new network architectures, based on a multitude
    of wavelengths, that are configured scalable
    while under customer control

28
Future Directions Optical Networks - CAnet 4
  • A Grid based on optical wavelength routing
  • Network scalable to any number of wavelengths
  • To give backbone access points at the edge of the
    network (and ultimately their participating
    clients) the ability to setup and manage their
    own wavelengths across the network thus allow
    direct peering between these access points using
    dedicated wavelengths optical cross connects
    that they control manage

29
Future Directions Optical Networks - CAnet 4
(cont.)
  • To allow the establishment of wavelengths by the
    backbone access points their participating
    institutions in support of QoS grid
    applications
  • Includes sharing of wavelengths with European
    Asian partners
  • To allow connected regional and community
    networks to setup transit wavelength peering
    relationships with similar like minded networks
  • To offer an optional layer 3 aggregation
    service for those networks that require or want
    such a facility

Future Directions GridsThe General Concept (1)
  • The structure of a computer-based Grid is like a
    utility grid or transportation grid - nodes
    connected to a physical network (e.g., power
    generation facilities connected to electricity
    users via a network of electrical transmission
    storage facilities)
  • Thus, a Grid is a scalable wide-area network
    linking data collecting and data handling
    capabilities, often with computational resources
    and support infrastructure distributed across the
    network

33
Future Directions GridsThe General Concept (2)
  • In computer-based Grids
  • the nodes are computing resources like high
    performance computers, massive databases
    scientific instruments
  • the physical network is comprised of wire line
    and wireless communications networks
  • the enabling power of a Grid is achieved through
    software environments that allow sharing of
    geographically distributed resources for data
    gathering storage, computation and visualization

34
Future Directions GridsTypes of Grids
  • Access Grids provide remote use of
    instrumentation over geographic distances
  • Computational Grids primarily used for large
    scale-computing
  • Data Grids provide a means of distributing
    sharing massive data sets

35
Future Directions GridsSocio-Economic Impact
  • Longer-term influences anticipated to include
  • development of new science engineering leading
    to new technologies, products and services thus
    creating comparative competitive advantages
  • enhanced capabilities innovative new models of
    E-learning, E-government, E-health
    E-commerce, to name a few
  • new forms of human, human-machine
    machine-to-machine collaboration leading to a
    plethora of new opportunities

36
Future Directions Web ServicesThe General
Concept
  • Web Services allow for two-way transactions
    compared to the passive environment of most of
    the Web were users extract information from a
    given site but do not post information to that
    site
  • Web Services allow Web-based computer-to-computer
    communications information sharing
  • Web Services happen in a back-end context are
    transparent to the user

37
Future Directions Web ServicesA Definition
  • Web Services are enabling technologies that
    facilitate the assembly integration of
    applications in order to create new, more
    meaningful and/or more user-specific applications

38
Future Directions Web Services Assimilating the
Capability
  • Web Services are expected to have major
    implications for the future of on-line teaching,
    learning research
  • The technical architecture that will drive Web
    Services needs to be properly defined
    communicated throughout the educational community

39
Summary E-Learning Tomorrow (1)
  • Universally improved access to the Internet
  • Content developed from repositories of multimedia
    learning objects
  • Courses designed for broadband will allow for
  • the use of rich multimedia content
  • dynamic interaction between content the student
  • Global community of students studying learning
    from anywhere, anytime at any pace

40
Summary E-Learning Tomorrow (2)
  • If social economic benefits of anyone,
    anywhere, anytime, any pace E-learning are to be
    realized, there is a requirement for widespread
    access to broadband to where ever learners need
    learning (e.g., especially the home)
