Information Highway
  • Todays days Internet is the Information highway.
    The vast amount of information is available in
    the home through Internet. With communication
    convergence, information highway has attained a
    new dimension. The world is an information
    highway now with a multitude of different avenues
    for receiving it.
  • The global information and communications network
    includes the internet and other networks and
    switching systems such as telephone networks,
    cable television networks and satellite
    communication networks.
  • The internet, bulletin board services, online
    services and other services that enable people to
    obtain information from telecommunication
    networks. There is currently a national debate on
    how to shape and control this type of
    information.
  • Many people believe that the information highway
    should be designed and regulated by government,
    just like conventional highway systems. Nearly
    everyone agrees that accessing the information
    highway is going to be a normal part of everyday
    life in the current future.

  • The above figure says that the information in
    the form of packets sent through the mail,
    communications sent over a network are broken
    down into small packets and wrapped with shipping
    and assembly instructions, called protocols.

Knowledge Society for ICT, Education and
Development
  • The term Knowledge Society generally refers to
    a society where knowledge is the primary
    production resource. A knowledge society creates
    share and use knowledge for the prosperity and
    well-being of its people. In the social sphere,
    the knowledge society brings greater access to
    information and new forms of social interaction
    and cultural expression.
  • Education is of huge importance in the knowledge
    society, as a source of basic skills, as a
    foundation for development of new knowledge and
    innovation, and as an engine for socio-economic
    development. Education is, therefore, a critical
    requirement in creating knowledge societies that
    can stimulate development, economic growth and
    prosperity.

12
  • Thus, rather than considering ICT, education and
    development as separate pillars required to
    support the knowledge society. One may view
    education and development as interrelated drivers
    for development. In this view, ICT is the enabler
    for both innovation and education without which
    a knowledge society cannot be realized. This is
    visually captured in the following figure

education required for development and sustenance

Contd..
  • The potential impact of ICT on learning is the
    vision that it enables learning anywhere,
    anytime, and anyhow. With ICT, knowledge is not
    constrained by geographic, and offers more
    possibilities for sharing, archiving, and
    retrieving knowledge. In addition, the knowledge
    society and widespread use of ICT generates a
    need for new digital skills and competences for
    employment, education and training,
    self-development and participation in society.
    ICT has potential to widen access to educational
    resources, improve the quality of learning and
    improve management efficiencies of the education
    system.

14
Scope of ICT in Education
  • www is updating the knowledge warehouses for
    students, teachers and scientist due to
    tremendous progress of ICT. A person from village
    also can refer the latest information and
    research everyday. Open universities and distance
    education through ICT are new openings for
    working people to acquire, knowledge to study at
    home also.
  • Television broadcast is one of the best
    communication media to educate the students,
    farmers, sportsman with latest information with
    video clips. The costly and difficult
    experiments, advance surgery for medical students
    etc. can be viewed.
  • The curriculum, information about text books,
    reference books and references are available on
    internet.
  • Audio cassettes, video tapes, audio and video
    CDs, video multimedia interactive CDs are
    available in market for all types of students
    from KG (Kinder garden) to PG (Post Graduate).
  • Instead of overhead projectors, now LCD
    projectors can be viewed for effective teaching
    for large number of students.
  • The man power, the human mistakes can be avoided
    by on-line examination. Maharashtra State Board
    is conducting on-line examination for Information
    Technology (IT) subject for XII standard.
    Maharashtra Knowledge Corporation (MKCL) also
    conducts on-line examination for MSCIIT course.

15
ICT and changing role of educators to promote
literacy
  • It will become increasingly easy to create
    educational environments where the online world
    is integrated with the physical campus. The
    students will face a new set of educational
    challenges. To learn skills of using ICT in
    education, the professional role of teachers as
    mentors, able to impart the wisdom that only
    experience can provide, will grow in importance.
  • Following an overview of a few key ways in which
    educators will need to be able to mentor and
    guide learners in this environment.
  • Preparing background to accept computer
  • Learner
  • Planner
  • Teaching
  • Examiner

Changes will takes place in traditional education
system due to ICT
From To
Curriculum Institutional design curriculum or prescribed course. Learners need based curriculum courses demanded by learners.
Content Fixed or stable content for specific period Rapidly changing content
Teaching-learning method Teaching-learning process synchronous On campus or classroom Traditional student Face-to-face communication Detailed classroom teaching Asynchronous teaching-learning process. At home or work place Modern age students Electronic communication (one way, two way or multiple mode, etc) Decentralized learning, e-learning, use of PPT on LCD.
Classroom Communication is oral, lecture method. Technology related classroom communication. E.g. CDROM, internet and web related technology or multimedia presentation
Management Traditional methods are adopted for management Management through camera, office and library transaction of management through ICT
Evaluation Traditional methods of evaluation written, oral, practical exam, incidental observation. Online evaluation, evaluation through software, data representation and presentation and online result.

ICT and Challenging skill requirements
  • Education systems are faced with a need to
    provide formal instruction in information,
    visual, and technological literacy as well as in
    how to create meaningful content with todays
    tools. However, it is important to consider
    expanded definitions of these literacys that are
    based on mastering underlying concepts rather
    than on specialized skill sets. Education systems
    need to develop and establish methods for
    teaching and evaluating these critical literacys
    at all levels of education.
  • Basic Skills
  • Teaching Advanced Skills
  •  
  • The skill of Complex Communication
  • Making effective oral and written arguments,
    collecting information from others.
  • Can similarly be taught using existing subject
    matter. But teaching this skill requires both a
    change in emphasis and additional time.
  • Time needed to review and grade oral
    presentations and frequent student essays.

18
Transformative impact of ICT changing stories
  • The capacity of ICT to reach students in any
    place and at any time has the potential to
    promote revolutionary changes in the traditional
    educational model.
  • To avoid crowded classrooms, a school may adopt a
    dual-shift system without reducing its students'
    actual study time.
  • ICT can make multi grade schools in areas with
    low population density.
  • ICT can provide courses that small rural or urban
    schools cannot offer to their students because it
    is difficult for those institutions to recruit
    and retain specialized teachers, particularly to
    teach mathematics, science. Schools that do not
    need a full-time Physics or English teacher can
    use radio, TV, or online instruction, using
    already developed multimedia materials and
    sharing one "teacher" among several schools.
    Alternatively, retired or part-time teachers who
    live hundreds of miles away can teach the online
    courses.

  • Information Communication Technology used well
    in classrooms, enhance the learning process, in
    the following ways
  • Students are motivated only when the learning
    activities are authentic, challenging and
    multidisciplinary. Videos, television, and
    computer multimedia software can be excellent
    instructional aids to engage students in the
    learning process.
  • Teachers have a hard time teaching, and students
    have a hard time learning.
  • They provide opportunities for students to
    practice basic skills on their own time and at
    their own pace.
  • They allow students to use the information they
    acquire to solve problems, formulate new
    problems, and explain the world around them.
  • They provide access to worldwide information
    resources.
  • They offer the most cost-effective (and in some
    cases the only) means for bringing the world into
    the classroom.
