Education
is of extreme importance as it is key to equipping the workforce
with the skills needed to develop national economies. The
importance is exemplified by the “Education for All”
movement, a global commitment to provide quality basic education
for all children, youth and adults, which links directly
to the UN Millennium Development Goals (MDGs). Sustainable
development of quality primary education is dependent on
complementary development in the secondary and tertiary
education sectors. With economies relying more and more
on the generation and application of knowledge, productivity
is increasingly dependent on the development and spread
of technological innovation. Higher education and life-long
learning are today more important to development than ever
before, due to the role knowledge plays in development –
“knowledge is power”.
But
inequalities in access to quality education are still tremendous.
The situation, for example, in Sub-Saharan Africa is particularly
dire. In 2000, only 5 per cent of the higher education age
group was enrolled in universities compared to a world average
of over 16 per cent. The problem of inadequate higher education
capacity, dwindling government support, low enrollments
in the secondary system and the introduction of school fees,
have resulted in limited and unequal access to higher education.
There is a need for large scale interventions to improve
the higher education sector not only in Africa, but also
in other regions, for example Latin America, Arab States,
Asia and South-East Europe, if the problems of access and
inequality are to be resolved.
In
many countries enrolment in tertiary education is significantly
lower than the norm and secondary education has expanded
to the point that large numbers of qualified school drop-outs
cannot get access to tertiary education. There is an unsatisfied
demand for tertiary education but there are not enough institutions
and trainers to train them, resulting in a shortage of qualified
labour within the national economies.
Low
enrolment in tertiary education is due to several factors.
The first is funding. There are competing needs that governments’
educational budgets have to satisfy and the relatively high
unit costs of tertiary education restrict university expansion.
The second is costly infrastructures, including student
housing, which will increase overall university costs. The
third is the lack of qualified academic staff, particularly
for those areas in which there is the strongest demand from
the private sector, such as computer science. In many countries
these problems are exacerbated by the dramatic effects of
HIV-AIDS both in skill shortages the result of high mortality
rates and in reducing the effectiveness of the workforce
through morbidity.
Furthermore,
there is an issue relating to the general quality of graduates
from the secondary school system. Curricula that are currently
in use at secondary level are often outmoded and cannot
be easily modified because of a lack of funds to update
teachers and produce new materials. Weaknesses in science
teaching at this level hamper learning of sciences at tertiary
level and (as a result) the ability of the countries in
question to compete in a global world. Graduates who do
not acquire the qualifications to proceed to the tertiary
level do not acquire the skills required to function effectively
in civil society. There are direct correlations between
investments in higher education on one hand and economic
growth on the other hand.
There
is a great uncertainty about the changing labour market,
coping with an avalanche of new knowledge, and new demands
on education in both traditional and emerging fields. There
is a need to provide educational services to everyone, anywhere,
anytime with a focus on learning and teacher empowerment
- all under conditions of an ever-expanding base of learners
and limited physical and human resources to get them ready.
Economic,
societal, political, and technological developments require
that all members of society have a minimum level of education.
The biggest challenge is to reach individuals and groups
that are historically underserved, such as girls and women,
groups with special needs, rural populations, and adult
workers.
Lifelong
learning and vocational training cannot be confined to the
traditional classroom and early life training. To cope with
the diversity, complexity, and changing demands for education
services, delivery must extend beyond the traditional “face-to-face”
teaching. It needs to include distance education, enrichment
through mass media, and non-formal instruction and training.

Role of Satellites in Education
The
evolution of technologies over the past decade, in particular
the utilisation of such telecommunications technologies
as satellites, has increased know-how about how to effectively
deliver distance education and integrate ICTs into educational
systems. Many countries have achieved successes in combining
pedagogical and organizational goals to create innovative
educational solutions using modern information and communication
technologies. The early experiences and a large number of
present distance training initiatives have focused on increasing
access and enhancing the kind and quality of instruction
through the delivery of education materials at a distance.
These include both distance education based on postal exchange
of educational correspondence between teachers and remote
learners, and the use of radio and television to broadcast
non-interactive education programmes.
Today,
distance education consists of a richer set of practices.
These include education activities with geographical or
time drift between teachers and learners with possibilities
for self-paced education, instructor- and tutor-facilitated
education and instructor-led education. Current models offer
two-way synchronous and asynchronous communication channels
to provide for teaching and tutoring that has alternative
feedback paths, that allow learners to communicate among
themselves, and to provide all education partners with quick
access to other educational databases, resources, methodologies
and tools.
Open
learning is yet another concept that introduces additional
flexibility in the learning process and in curricula certification.
The goal is to facilitate access to education for learners
facing constraints when it comes to admission and required
prerequisites, pace of learning, and to alternate ways to
earn certification and qualification. Open learning can
include both distance training and distance education. Open
learning is well adapted to life-long learning and professional
development outside the traditional academic environment.
Access
to education is not only about access to technology but
also access to content, services, expertise, through different
forms ranging from off-line databases (such as directories,
training materials, guidelines) to distant publishers, databases,
web sites, and other open distance learning resources that
can be reached in real time or not.
This
new educational and technological context requires of educational
planners and providers the operation of a variety of specialized
sub-systems interacting with each other and managed in a
very comprehensive way. The development, delivery and management
of e-learning has emerged as a complex process that includes
different stages and requires a large variety of actors
and modalities of work, producing deliverables, products
and services. The educational delivery system is in some
ways similar to an industrial process: there are learners,
teachers and trainers, instruction and multimedia designers,
information and ICT professionals, managers, and decision
makers, and all these must work smoothly together.
Networking
of the various education actors is essential for providing
them with an environment primed for teamwork, open to the
possibilities of exchanging knowledge, know-how, best practices
and information, for teaching and learning, and for delivering
and accessing quality education.
Such
a model is as follows.

Technologies used in distance and open education systems
are a combination of traditional technologies and communication
channels to include face-to-face sessions, correspondence,
telephone and fax, radio and television, audio and video
cassettes, and other off-line and on-line electronic media
such as CD-ROM, e-mail and electronic forums, television
broadcasting, digital audio and video multicasting and streaming,
digital libraries and e-books, shared and distributed applications
and the World Wide Web. They are used for the development
and storage of education content, provision of access to
and dissemination of educational materials, for managing
learning processes and ensuring the quality of education.

The Experience of India
India
has a long experience in the use of satellite for education.
Its first satellite service for education was launched in
1975 within the framework of the Satellite Instructional
Television Experiment.
Video
tapes were prepared by All India Radio/Doordarshan in Delhi,
transferred to the Ahmedabad Centre and beamed from its
ground station to the Satellite. The programmes achieved
considerable progress in the areas of information, awareness
and knowledge of health, hygiene, family planning, political
processes and overall contemporary thinking. In addition
50,000 rural teachers were enrolled during the experiment
in a multimedia programme, training them in the teaching
of mathematics and general science. The simplicity of community
television sets and the efficiency of their maintenance
were sufficient to keep 90 per cent of the sets working
at any time providing a picture quality better than the
normal VHF receivers in Indian cities. One and a half hours
of broadcasting in the morning were devoted to school children
and two hours in the evening to general audiences, which
averaged 100 people per set. From a total of 2,400 villages
in six states receiving the programmes, 27 were chosen for
continuous analysis, with 270 interviews per day.
Mr.
Yash Pa1, the Director of the Space Application Centre,
Ahmedabad, reported that the experiment was a valuable experience
for all, that the benefits were greater for the under-privileged
classes, such as females and illiterates, and that these
gains increased as TV viewings multiplied.
In
1993, the Indira Gandhi National Open University (IGNOU)
and the Indian Space Research Organisation (ISRO) initiated
collaboration for the development of a satellite network
for education by delivering IGNOU distance education programmes.
In 2000, Gyan Darshan launched from IGNOU a bouquet of TV
channels as a common channel for the Indian education system.
Today, IGNOU has 775 nationally distributed interactive
terminals.
In
September 2004, ISRO launched EDUSAT in a Geo-Stationary
Orbit. EDUSAT is the first Indian satellite designed and
developed exclusively for serving the educational sector.
It is mainly intended to meet the demand for an interactive
satellite-based distance education system for the country.
It
reflects India’s commitment to use space technology
for national development, especially for the development
of the population in remote and rural locations. EDUSAT
is a collaborative project between the Ministry of Human
Resources Development (MHRD) and ISRO. MHRD proposed to
use the ICT capabilities of the EDUSAT satellite for Elementary
Education, Literacy, Vocational Training and Teacher's Training.
A later phase will include agriculture, health and community
development programmes. EDUSAT, in its first stage, is providing
benefits to:
- Indira
Gandhi National Open University (IGNOU);
- All
India Council for Technical Education (AICTE);
-
Indian Council of Agricultural Research (ICAR);
-
National Council of Educational Research and Training
(NCERT);
-
University Grants Commission (UGC).
The
adopted education strategy is based on linking existing
resource centres like IGNOU, NCERT, SIET to share initial
expertise and experience, translating and transforming available
content and the participation of some of the best teachers
and experts available at the State and national levels for
recording their lectures and their interactions with students.
The
EDUSAT satellite has six Ku-Band transponders and six C-Band
transponders, as shown in the map below.

Critical Success Factors
The
quality of results obtained by using ICTs and satellites
in education does not depend solely on the technology used
in distance education delivery. The level of education and
the methodology for disseminating education programmes and
implementing projects are also important. A number of distance
education projects, using radio or television, did not produce
the expected results and failed because:
-
they intended to reproduce traditional face-to-face education,
especially in primary education;
- their
scope was too ambitious and the educational and social
risks were underestimated;
- their
human resources were mainly based on outside technical
assistance, ignoring local capacity; and finally,
- some
of them were principally technology driven.
In
most developing countries the constraints facing ICT and
education are related to policy matters, insufficient financial
resources, poor infrastructures and weak technical capacities
and lack of skilled staff. Important parameters are the
appropriateness of technologies, the suitability and quality
of instructional materials and educational services made
available, learning effectiveness and appropriation of new
ways of work, and the cost benefit ratio. It is, therefore,
important that policy makers are sensitised to the need
for national plans for ICT in education at all levels.
For
example, unfavourable telecommunication policies impede
ICT-enhanced education programmes, network-based activities
and interaction, and access to sources of information. Some
countries charge a high tax on computing and telecommunications
equipment making the costs unaffordable or prohibit the
installation and use of some telecommunications technologies,
which limits the utilization of large bandwidth capabilities.
Another example is the price of computers and software licenses,
which are significantly higher in developing countries than
in industrialized countries. In this context, cooperation
with the private sector is required so as to make equipment,
software and services affordable, especially to educational
and research institutions. Free and open source software
can be a means to strengthen long-term capacities.
The
appropriate and effective use of technologies requires access
to technology, content and services, the availability of
competent, committed people, and the continued development
of their capacity. In this context, capacity building of
e-education professionals in charge of developing content
and networks, delivering education programmes and services,
managing the e-learning process and the interconnecting
networks, is a key success factor. Capacity building should
be approached in a systematic way based on a comprehensive
definition of profiles and skills. Such a definition includes
all education professionals concerned, such as teachers,
e-learning and distance education designers and tutors,
support and administrative staff, education technology specialists
and information professionals.
A
number of assumptions lead to success (or failure) of distance
education, in particular the following:
-
Distance education and learning are not similar to traditional
face-to-face education and training;
-
Face-to-face teaching and education support is strongly
dependent on the age of learners ranging from children
to adults;
-
The quality of distance training materials is often poor
and their interactive character undeveloped, in particular,
their capabilities for simulation and virtual action;
-
The wide range of skills and profiles required from human
resources involved in distance learning and e-learning;
-
The need for education-driven policy and projects rather
than technology-driven.
Distance
education has been frequently implemented through pilot
projects and, therefore, is not considered a component of
regular education requiring a large spectrum of inputs,
in which capacity building takes a large place. A number
of initiatives for the introduction of ICTs in education
failed because of an under-estimation of capacity building
requirements, limiting it to some technical skills. In fact,
applications of ICTs in education require a wide range of
skills and the definition of new multidisciplinary professional
profiles.
In
this context, the international community has underlined
a number of priority areas for integrating ICTs in education,
and has included them in the World Summit on Information
Society (WSIS) Plan of Action and UNESCO’s Information
for All Programme objectives:
-
The creation of programmes for capacity building with
an emphasis on creating a critical mass of qualified and
skilled ICT professionals and experts,
- The
integration of ICTs into pedagogy, both directly into
curricula at all levels, and indirectly, as a means to
improve education through services to all education actors,
-
The development and delivery of distance learning, training
and other forms of education and training as part of capacity
building programmes,
- The
development and dissemination of innovative ICT-based
alternative educational delivery systems,
- The
deployment of new forms of ICT-based networking, linking
education, training and research institutions between
and among developed and developing countries and countries
with economies in transition.
-
Cooperation with the private sector to enhance the capacity,
notably, of leaders and operational staff in developing
countries and LDCs, and to apply ICTs effectively in the
whole range of educational activities, and
-
International and regional cooperation in the field of
capacity building, including country programmes developed
by the UN and its Specialized Agencies.
In
May 2005, UNESCO and the Club of Rome organized a conference
in relation to Chapter 4 “Capacity building”
of the “Declaration of Principles” and the “Plan
of Action” respectively, adopted by WSIS in December
2003 in Geneva, Switzerland. Chapter 4, paragraph 11 of
the WSIS Action Plan stated, “Everyone should have
the necessary skills to benefit fully from the Information
Society. Therefore capacity building and ICT literacy are
essential. ICTs can contribute to achieving universal education
worldwide, through delivery of education and training of
teachers, and offering improved conditions for lifelong
learning, encompassing people that are outside the formal
education process, and improving professional skills.”
The
Conference aimed at discussing the use of ICTs, including
satellites for capacity-building, and their strategic role
in achieving the UN’s Millennium Development Goals
(MDGs) and for building knowledge societies. Its main focus
was on new delivery methods of formal learning and associated
skills development. It gave particular attention to the
special needs of marginalized groups in areas that are un-reached
by the traditional education systems but could be given
access to new forms of education delivery through satellite
technologies.
The
purpose of the Conference was to identify prerequisites
and success factors for capacity-building using ICTs to
collect and disseminate testimonies and case studies from
around the world on how to make a quantitative leap in development
by using ICT, and to give the IT industry a platform from
which to present technology that is both appropriate to
the development environment and will meet the needs of emerging
markets.
The
Conference identified twelve factors that are critical for
the success of projects in the area of ICT and capacity
building. They should correspond to a clear vision and have
a holistic and integrated approach. Local ownership and
community participation are required. Government support
and multi-stakeholder partnerships are essential. Such project
should have the goal of developing human capacities, not
only skills but state of mind and attitude. A large contingent
of women should be involved. Projects should be adapted
to local communities and contextualized to take account
of local competencies (e.g. in terms of language), curricula
and content. Projects should be based on flexible, innovative,
and appropriate technology that require changes in attitudinal
approaches and state of mind in order to meet the different
levels of sophistication of the users. Projects must become
integrated in the life of community to be sustainable and
include monitoring and evaluation mechanisms for identifying
intermediary and final outcomes that can be measured.
