Analytical Survey of information and communication technology in special education
Executive Summary
Promotion of education is a fundamental
objective of UNESCO. By definition, people with disabilities are often
restricted in the extent to which they can take a full part in the society in
which they live, but many of those restrictions can be reduced by their
receiving good education.
The most important educational resource is people –
teachers. However, it has to be recognized that in the present and the
foreseeable future, economic and political restrictions are unlikely to be such
that adequate supplies of suitably trained teachers will be available to
completely fill the need for them. When human resources are inadequate, it is
often easier to procure and provide technological solutions and it is most
fortunate that in special education, technology can play a highly beneficial
role. Although economic restrictions can affect access to technology, it can
represent a good investment.
This document outlines the role that information and
communication technology (ICT) can achieve in special education, with the
objective of getting it more widely adopted and used in UNESCO Member States.
It establishes some definitions and then outlines the role ICT can play in
education in three identifiable roles:
Prosthetic
Technology can substitute or compensate
for the lack of natural function. This is important for all people with
disabilities and has a particular importance in education.
Educational
Again, ICT is growing in importance in all
forms of education but can have a particularly valuable role for this with
special educational needs.
Communication at a distance
Technology can mediate communication
between people with disabilities. Furthermore, where teachers are in short
supply (as in special education) distance teaching methods can help to share what
expertise there is. A mapping of technologies to communication needs is
presented.
Educational and other cultural challenges may be difficult
to address because of economic, social and political constraints and sometimes
technology is the easiest way around some of those constraints. This is the
case in special education where ICT can have a significant role to play and
this can apply in many different environments regardless of their level of
educational, technological and economic development.
Analytical Survey of information and communication technology in special education
Preface
In 1988 UNESCO
published the Review of the Present Situation of Special Education, presenting
information gathered in 1986‑1987, covering issues related to policies, legislation,
administration and organization, teacher education, financing and provision for
special needs education. The Review was widely disseminated and served as a
reference to a number of studies, seminars and other national activities.
In view of the incessant
demand for information of this nature, reflecting on trends and developments in
this domain, UNESCO carried out an up‑date of the review in 1993-1994. Ninety
Member States were initially contacted to contribute to this exercise, sixty‑three
of which responded. Replies were received from countries representing the
different world regions as follows: thirteen from Africa, seven from Arab
States, twenty‑one from the Europe Region, thirteen from Latin America and the
Caribbean, and nine from Asia and the Pacific.
UNESCO’s action
also focuses on reducing the educational inequalities to which some groups
having only limited access to traditional forms basic education are exposed,
such as street children, children who are the victims of war, refugees and displaced
persons, the handicapped, and all those who have special educational needs.
With the assistance of a variety of partners, the Organization brings together
administrators, decision‑makers and educators at regional and sub‑regional
seminars in a bid to come tip with answers to the special needs of these children. It provides support
for pilot activities, organizes training workshops, fosters exchanges of
experience, and produces guides and other types of material to help educators
and national officials make better provision for everyone to have equal access
to education.
Although some
countries have made major strides in education of people with disabilities, the
fact remains that, for the majority of countries, especially developing
countries, the reality is bleak, both in terms of access and quality education
for disabled persons. The findings of the UNESCO survey conducted in 1986/87
revealed that 34 out of the 51 countries supplying information had fewer than
1% of all pupils for whom special educational provision had been made.
The world-wide
discrepancy between needs and provision has stimulated a reappraisal of
educational strategies. Many countries, after the World Conference on Education
for All, are taking steps to enhance services for children with special
educational needs within mainstream education and community-based programmes.
The main thrust of
UNESCO activities today is on policy and planning and teacher training within
mainstream education. To this end,
UNESCO organized a series of five regional seminars to mobilize support of
education policy‑ and decision‑makers for ensuring wider access for children
with special educational needs into the regular school system, and to encourage
reorientation of education strategies.
The scarcity of materials
and literature at the disposal of teachers, parents, and community workers in
developing countries has prompted UNESCO to publish a series entitled “Guides
for Special Education”. More
recently, in connection with training, UNESCO has ventured into the production
of video materials for parent education and early intervention.
In 1994, more than
300 participants representing 92 governments and 25 international organizations
met in Salamanca, Spain, at the World Conference on Special Needs Education: Access
and Quality, to further discuss the objective of Education for All by
considering the fundamental policy shifts required to promote the approach of
inclusive education. The Salamanca
Statement and Framework for Action on Special Needs Education adopted
unanimously at the Conference, are based on the principle of inclusion that ordinary schools should accommodate all
children, regardless of their physical, intellectual, emotional, social,
linguistic or other conditions. It reaffirms the commitment to Education
for All, recognizing the necessity and urgency of providing education for all
children, young people and adults.
‘Regular schools with this inclusive
orientation are the most effective means of combating discriminatory attitudes,
creating welcoming communities, building an inclusive society and achieving
education for all...’
(Article
2, Salamanca Statement)
'Educational policies at all levels,... should
stipulate that children with disabilities should attend their neighbourhood
school that is the school that would be attended if the child did not have the
disability’
(Article 18 Salamanca Framework for Action)
The Salamanca
Statement and Framework for Action called upon UNESCO:
• To
ensure that special needs education forms part of every discussion dealing with
education for all in various forums;
• To
mobilize the support of organizations of the teaching profession in matters
related to enhancing teacher education as regards provision for special
educational needs;
• To
stimulate the academic community to strengthen research and networking and to
establish regional centres of information and documentation; also, to serve as
a clearing house for such activities and for disseminating the specific results
and progress achieved at country level in pursuance of this Statement;
• To
mobilize funds through the creation of an expanded programme for inclusive
schools and community support, which would enable the launching of pilot
projects that showcase new approaches for dissemination and to develop indicators
concerning the need for and provision of special needs education.
Furthermore, the 28th
Session of the General Conference also invited the Director‑General to take
steps in ensuring that the concerns of person with disabilities will be
reflected throughout the Education Sector Activities, especially in policy and
planning, as well as in the Culture and Communication Sectors. It also called
for reinforcing the inter‑agency collaboration with ILI, UNICEF and WHO.
In pursuance of the
implementation of the 28C Resolution 1.5 adopted by the 28th Session
of the General Conference, and in line with Article 4 of the Salamanca
Statement, UNESCO organized an informal consultation in March 1995 with
Denmark, Finland, the Netherlands, Norway, Portugal, Spain, and Sweden, to
discuss the project proposal ‘Inclusive
Schools and Community Support Programmes’ with the aim of mobilizing
support from donor countries.
The ‘Inclusive
Schools and Community Support Programmes’ project departed from the principle
endorsed at Salamanca, namely, that it is better and socially and economically
more efficient to integrate ‑ to include ‑ children with disabilities and
learning difficulties in mainstream school and regular education programmes
than to segregate them in specialized institutions or, worse, not educate them
at all. The project’s aim thus has been to foster wider access and quality
education for children and youth with special educational needs, seeking to
promote their inclusion in regular education provision.
The Project aspires
to identify, support, and disseminate information on small‑scale innovations at
the national level, and is intended to serve as a catalyst for all countries
that wish to carry out initiatives in line with the Salamanca Framework for
Action. The Project target areas are policy and school development, teacher
education, education of the deaf, adult education, transition to active life,
development of educational support services in schools and communities, parent
education, early childhood education.
The basic
parameters of the ‘Inclusive Schools and Community Support Programmes’ project
place emphasis on:
• small
scale pilot/demonstration projects with built‑in dissemination strategies, i.e.
to ensure sustainability and replicability;
• capacity
building in the form of trained teams of professionals at national, provincial
and local levels;
• upstream
work to incorporate new initiatives into national planning;
• genuine
parental and community involvement in new initiatives;
• benefits
to a wider number of countries than those directly participating through
networking and exchange opportunities, particularly at the sub‑regional level.
The establishment
of the UNESCO Institute for Information Technologies in Education (IITE) in
Moscow, based on resolution 6 adopted by the General Conference at its 29th
session is part of an overall plan to reinforce the Organization’s activities
concerning the introduction and application of information and communication
technologies in education.
The Institute,
which benefits from the active and generous support of the Russian Federation
Government, is specifically mandated: to assist Member States in developing
their national infrastructure in this field; to train educational personnel; to
facilitate dissemination and exchange of information on the subject; to
mobilize partnerships within and outside UNESCO in all fields of the
Institute’s competence.
The 30th
Session of the General conference of UNESCO indicated the following priorities
of IITE:
• an
international network of national focal points established as an interactive
system fostering the exchange of information and experience;
• an
international project ‘ICTs in Education: State of the Art, Needs and
Perspectives’ focused on national action plans and policy documents launched;
• a
set of training and self‑training modules for different categories of
educational personnel prepared and tested;
• partnerships
and co-operative agreements with existing institutions, programmes and
organizations established;
• national
pilot projects launched.
Following its
mandate IITE launch several projects adopted by the international IITE
Governing Board, and among them the project ‘ICTs in Education for People with
Special Needs’ aimed at providing an access to electronic educational materials
for this category of learners and other activities in this direction.
Starting the
investigation IITE met such difficulties as a lack or fragmentary character of
information on the use of ICTs in SNE. Collecting and systematization of
information on application of ICTs in SNE seems to be the most important and
complex task at the first stage. Stoking and analysis of this information
should become a basis for true recommendations for policy‑makers, educators,
learners and designers of soft and hardware and teaching/learning methodology.
That is the reason of drafting the first Analytical survey on this issue.

Analytical Survey of information and communication technology in special education
1. Foundations
Promotion of education is a fundamental
objective of UNESCO. By definition (UN 1981),
people with disabilities are often restricted in the extent to which they can
take a full part in the society in which they live, but many of those
restrictions can be reduced by their receiving good education.
The most important educational resource is people –
teachers. However, it has to be recognized that in the present and the
foreseeable future, economic and political restrictions are unlikely to be such
that adequate supplies of suitably trained teachers will be available to
completely fill the need for them. Apart from other restrictions, education is
a self-sustaining process; to have a good supply of teachers tomorrow we must
be educating numbers of children today. The availability of teachers trained in
the speciality of teaching children with disabilities is even lower.
When human resources are inadequate, it is often easier to
procure and provide technological solutions and it is most fortunate that in
special education, technology can play a highly beneficial role. Although
economic restrictions can affect access to technology, it can represent a good
investment.
2. Objectives
This document outlines the role that
information and communication technology[1]
(ICT) can achieve in special education, with the objective of getting it more
widely adopted and used in UNESCO Member States.
3. Fundamental assumptions
Technology is no substitute for human
teachers – but can be a most valuable tool to supplement their contribution.
ICT is rapidly expanding and developing. Any description
herein would inevitably be a ‘snap shot’ of the situation at the current time,
one that would be out of date before the report is even published. Therefore,
individual technologies are not described in any detail. Furthermore, it is
recognized that technology ages rapidly. This implies that what is available
today in technologically advanced states is not available in the less developed
ones, but by the same token, that technology will be available in those states
tomorrow. To reach the widest level of adoption we must not aim at the state of
the art.
By the same token, there is no point in trying to be
specific in this report about the state of the technology. It is better to
discuss in broad terms the capabilities of the technology and to encourage the
reader to pursue more timely sources of information with regard to specific
products and facilities.
The acquisition and use of ICT must be placed in an
appropriate context. An increased reliance on ICT can only benefit those who
have access to it. In other words, there is a real danger that exclusion (for
whatever reason: economic, physical, social, or whatever) will constitute a
handicap (see the definition below). Furthermore, it is likely that many of
those who will be excluded will be the same people who are already
disadvantaged. Efforts must be expended on preventing the creation of an
excluded underclass, but those efforts must be co-ordinated and appropriate;
for instance, there is no point introducing electronic technologies to
communities which lack electricity power supplies or which are confronting more
fundamental needs – such as food and shelter.
It must also be recognized that educational systems vary
between countries. In the particular context of Special Education, an important
dimension is that of integration versus separation. That is to say that many
countries are attempting as far as possible to educate all children in the same
institutions, regardless of disability status, whereas other systems prefer to
teach children in separate, special schools (which are often residential).
Clearly the form of education will be different in these various institutions –
as will the role of technology.
This report has been written to be concise, rather than
comprehensive. It is assumed that the target readers have little time to read
through a long document. For anyone requiring more details, a bibliography is
provided at the end.
4. Definitions
4.1. Impairment, disability and handicap
The World Health Organization (WHO) is in
the process of creating new classifications and definitions of disability in
terms of impairments, activities and participation (WHO,
1997), but
for the purposes of this document, it is adequate to refer to the existing
definitions, as presented in UN (1981).
Impairment
Any loss or abnormality of psychological,
physiological or anatomical structure or function.
Disability
Any restriction or lack (resulting from an
impairment) of ability to perform an activity in the manner or within the range
considered normal for a human being.
Handicap
A disadvantage for a given individual,
resulting from an impairment or disability, that limits or prevents the
fulfilment of a role (depending on age, sex and social and cultural factors)
for that individual.
No attempt is made herein to list disabilities. It is
impossible to be definitive, particularly given the fact that handicap is
socially and culturally dependent.
Special Education is that sector which deals with the
education of all people identified as being disabled. The objective of all
education is to enable the student to take a fuller part in society. So,
according to the above definitions, the effects of a good education should be
to reduce the handicapping effect of the disability.
The educational needs of people with disabilities are vastly
diverse. They have the same needs as everybody else to learn the basic skills
of literacy and numeracy to the best of their ability as well as other
abilities that are required in the society in which they live. At the same
time, they have (by definition), educational needs that others do not have.
(Often referred to as special educational
needs).
For some students these needs are concerned with access to
education and materials; a blind student cannot use printed materials and must
have non-visual alternatives. For others, the needs may be educational in
themselves. That is to say, for example, that a cognitive impairment may
inhibit the student’s ability to learn, such that they need to be taught in a
different manner from students without that impairment. Also the needs of some
students will be more fundamental and lower-level. For example, it may be that
their education has to include areas that most children master at home before
they ever commence formal education.
4.2. The role of ICT
Information is a fundamental commodity. It
is through the discovery of new information[2],
its dissemination and sharing that society advances. Fundamentally information
is not modality-specific (i.e. not tied to its form of presentation, be it
visually, as sounds or whatever). Information may be defined as the
characteristics of the output of a process. These characteristics enhance
knowledge, being informative about the process and its input. Hierarchies of
processes, linked together, provide a communication channel between each of the
corresponding functions and layers in the hierarchies. But the end user
(destination, addressee) for whom the information exists, is a person who is
trained to manipulate through modality-specific notions (which are formed by
percepts). Therefore, within ‘information technology’ modal aspect of
information maybe more essential for development of relations between person
and computer.
Education is concerned with the imparting of information –
not just the simple acquisition of declarative facts, but also procedural
information such as how to do things, even how to learn. Technology to aid in
the processing and communication of information is not new; it is at least as
old as writing. However, in the past 50 years, the development of that
technology has accelerated exponentially, mainly due to the invention of
digital electronics.
A vital recent development has been the convergence of
technology concerned mainly with the processing of information with that which
deals mainly with its communication. This is clearly seen in the emergence of
the Internet, whereby the processing power in each office and school can
(easily) be connected and communicate with corresponding systems anywhere else
in the world. The better this integration is realized, the more blurred the
distinctions become. We can reach the point where the user does not know
whether the information resource being accessed is held on the local machine –
and (more significantly) does not care
where it comes from. This convergence is what is referred to as information and communication technology
or ICT.
One of the difficulties of special education is that it
requires special facilities and skills. These may be hard to find and
expensive. At the same time, the number of children needing them within any
group, may be relatively small. Again, ICT may have a role to play in
disseminating and sharing special forms of education.
It should not be forgotten that ICT is part of the
curriculum in all developed countries. The very ubiquity of ICT in society
means that to not be educated in its use could itself be a handicap. Thus,
though the emphasis in this paper is on use of ICT in education, it should not
be forgotten that students with disabilities should also be educated regarding
the technology itself. There is some disagreement as to the appropriate
description for this discipline. ‘Computer literacy’ is a generally accepted
term. Reading literacy implies the basic ability to read – and not necessarily
a facility at reading. Therefore, to some people the analogy is that computer
literacy would imply only an elementary familiarity with the technology,
whereas what is required is a fluent facility with it.
Another role for technology is in assessment. People change
and develop. Some impairments are progressive, but beyond such a ‘medical’
view, people change in reaction to their education and other changes in their
environment. It is important therefore that assessments should be carried out
regularly and these can be assisted by the use of technology.
In this context it is inevitable that the technology should
be applied to education. Furthermore, it has particular strengths in educating
people with disabilities, as discussed in the following section.
5. ICT in Special Education: An intermediary role
5.1. Prosthetic uses
Many forms of disability affect learners’
ability to access standard educational materials and ICT can surmount some of
these barriers.
5.1.1. Access to text
The key to many uses of ICT is the
availability of data in a machine-readable form. This is most malleable and
capable of being transformed into different formats. Printed text is not
accessible to people with a number of impairments, but if the same material is
available as a computer file then it can be presented in any one of a number of
ways (including enhanced printed forms, such as large-print text).
Conditions that affect text access:
• blindness;
• partial
sight;
• dyslexia;
• illiteracy[3].
Most text is of a literary form, which is to say that it is
composed of the alphanumeric characters that are found in the ASCII code set.
However, a significant amount of text is written in special notations (beyond
the scope of ASCII). Most notable among these are mathematics and music.
Technology is less well developed for handing and transforming these notations.
5.1.2. Graphics
Pictorial forms of information can take a
vast range of forms from simple line diagrams to rich paintings. They differ in
form and purpose and correspondingly means of accessing them vary. The same
conditions, which affect access to text, also apply to graphical visual
presentations. Though there are no recognized conditions equivalent to dyslexia
or illiteracy with regard to pictures, it is clear that some people are better
at mentally processing and understanding them than others.
As special case of access to graphics is the graphical user
interface (GUI) as found on all modern computers. The interface consists of
graphical items, such as windows, icons and menus as well as text, and their
interpretation is a complex visual task. Thus, the advent of the graphical user
interface led to significant fears of blind people being excluded from computer
use. However, efforts put into addressing that problem have paid off and a
number of ‘screen reader’ programs are commercially available which give good
access to these interfaces.
As well as needing to read and appreciate graphics, it can
be important to be able to create them. Drawing programs can make it possible
for many people to generate good quality pictures and in some cases they may
make it possible for people to create pictures who could not using conventional
materials (notably blind people).
5.1.3. Writing
Some students lack the physical ability to
write. There are a number of alternatives that can be applied. Some are able to
use a standard keyboard and to type instead of hand writing. For those who may
have restricted dexterity, tools exist which can speed up their input by
reducing the number of key presses required, by anticipating subsequent
keypresses. Other people who lack the dexterity to type may be able to
wordprocess nevertheless by some form of keyboard emulation such that they
generate input on some other device, which is fed into the computer as if it
came from a keyboard.
There is a wide range of such devices available. The lowest
level of input is a single switch, which might be used by someone with severe
physical impairments, such as a tetraplegic. A switch would be operated by a
part of the body, which might be: a hand, foot, eye blinks, breathing (through a ‘sip and puff’ switch), the
head – or whatever part of their body they have sufficient control over.
Although simple, this form of input is also very slow. Different techniques
have been developed for the interpretation of single-switch input. One such
method is Morse code, which has the advantage of being long-established, and
has even been taught in mainstream education in some countries. Morse is quite
difficult to learn and remember, though, and some people chose instead to use
scanning, menu-based systems, which involve less learning and memorization. A
number of approaches exist which will maximize the amount of information
extracted from each switch press.
At the other end of the spectrum some keyboard alternatives
provide a high rate of input. Notable among these is speech input. Current
software can provide a good level of recognition of speech at conversational
speeds. There are some features to note though. First, current speech
recognizers are speaker-dependent and require training. Secondly, although
recognition levels are high, anything less than 100% can still be inefficient
in some real applications. Finally, English is the predominant language for
current systems. With time, we can expect improvements in all these aspects.
There are other people who have no difficulty with the
physical process of writing, but do have problems with composition. The largest
such group are those with forms of dyslexia which affect writing, but there are
also others who have different degrees of language impairment, perhaps due to
brain damage (possibly caused by trauma or stroke). A variety of tools exist to
assist such people. Modern word processors often have tools such as spelling
checkers, grammar checkers and outliners built in but there are also specialist
tools that will help with composition.
5.1.4. Speaking and face-to-face communication
Some people cannot communicate in speech. This may be due to
an inability to physically generate the sounds of speech or it may be due to
some language processing deficit. Clearly this is a handicap in most daily
activities, but will clearly have a particular effect on education.
A wide range of alternative and augmentative communication
(AAC) devices exist. They employ a range of input strategies, aimed to suit the
abilities of different users. Output may be in a written form, but most often
they produce synthetic speech, which is perhaps natural as it is speech that
they are intended to replace. The quality of the speech generated is most
important and is constantly improving. In spite of the fact that English (and
particularly American English) has received the most attention, synthesizers
for other languages are available and are constantly improving. Sign languages
are languages in their own right, but they tend to be used only by people who
need to use them. In other words, many deaf people learn sign, but not many
hearing people do. Also, there are a variety of sign languages, and they are
distinct from the spoken languages used in the same countries, so that, for
example, American Sign Language is quite different to British Sign Language
even though the spoken language is the same in those countries. All these
factors can contribute to the isolation of deaf people from the rest of the
community. For those who would prefer not to be so isolated, technology may
have a role to play. As yet, sign language interpretation and translation is
somewhat limited, but again it is probably only a matter of time before
adequate translation (such as sign to speech) is available.
There are a number of other possible uses of ICT in relation
to sign language. It has to be remembered that to many deaf people, sign is
their first language, and they can
have difficulties with spoken and written language. Sign may be presented
through technology, so that an animated figure on a screen might sign a message
in place of text or speech. Also, sign is by nature dynamic, so that
dictionaries of sign with animation on a computer screen are much richer than
books with static pictures.
5.1.5. Other therapeutic applications
The flexibility of ICT and the variety of input
and output forms that can be handled, creates possibilities for therapeutic
uses. For instance, speech inputs can be processed and displayed visually to
help deaf students improve the quality of their speech. Another example is that
gesture-based input has been used as the basis of physical therapy (Wong
1991; Pausch and Williams 1995).
5.2. Educational uses
Computer programs can be used to teach
directly to students[4].
They have a number of benefits. They offer a form of individual attention to
the learner. A program is infinitely ‘patient’ and can present a lesson or idea
repeatedly and consistently without variation or fatigue. That is particularly
useful in drill-and-practice lessons, where repetition is necessary in order
for a concept or skill to be learned. This can be most useful for children with
learning disabilities.
It is important in computer-aided learning that a machine
cannot be judgmental. Children with learning disabilities are accustomed to failing and will often adopt strategies
such that they can avoid situations in which there is a danger they may fail
again. They avoid the risk of failure. However, when interacting with a machine
there is not the danger of annoying or upsetting another person, no matter how
many mistakes one makes.
Much of the educational software currently available is
based on a playful, games-style approach. There is relatively little that is
designed specifically for children with learning or other disabilities, but it
is often possible to use software targeted at one group with others. The
increasing availability of multimedia forms of interaction is important, too.
For example, pre-literate students may be taught to read with the aid of
programs that will produce speech.
Almost all the other features of ICT mentioned in this
report can have a relevance to direct educational use of the computer. For
instance networks and communications can mean that educational programs can be
delivered at a distance. Similarly, the flexibility of input and output
channels that are available can be important. An example would be a child using
a simplified form of input such as a touch-sensitive pad, rather than a
keyboard. Thus lessons on handling money might be taught through pressing real
coins on a touchpad, to someone who would not be able to type arithmetic sums
on a keyboard.
There are reasons to believe that one particular group of
students with special needs can benefit from computer-based learning, and that
is those who are autistic. Autism is mainly a social handicap, characterized by
difficulties in relationships with other people and one suggestion is that such
people have less difficulty forming a ‘relationship’ with a machine.
Furthermore, regularity and predictability are important to autistic people and
computers are, by nature, consistent and logical.
An important example is the use of everyday computer tools,
especially word processors. As discussed elsewhere, the word processor may be
used prosthetically as a writing aid for someone who cannot write manually. It
can also be used, though, by someone who can write – but not very well. The
motivational effect of being able to produce a piece of written work which is
neat and correct and printed with high quality, can be significant, and with
the facilities of editing, correcting and printing this is possible for anyone.
Motivation is also apparent in that children often greatly
enjoy interacting with computers. Some programs – notably games – are
specifically designed to enhance motivation (Malone
1982),
but even with more mundane programs seem to capture children’s attention and
make them concentrate for longer than they find possible for other activities.
As has been stressed elsewhere, technology can never be a
substitute for the human teacher. It is in the area of educational software
that it is most tempting to try to make that substitution, but in general it is
best to see software as a tool that the teacher can choose to use. The best
software should be intelligent. That is to say that it should incorporate a
student model, a representation of the individual student.
5.3. Communication at a distance
ICT can be used as part of distance
teaching. This can be important when (specialized) teachers are in short supply
and have to be shared between geographically dispersed students and teachers.
Communication can take place in different modes and requires different rates of
information flow (bandwidth). These are all summarized in Table 1.

Table 1. Summary of communication styles
The different styles of communication have different
characteristics in terms of teaching objectives. For example, to demonstrate a
physical action, a synchronous (real-time) connection (presumably a video link)
is required, whereas the imparting of factual information can be achieved by a
low-bandwidth, asynchronous channel, such as email.
There is effectively a simple relationship between bandwidth
and cost: the greater the bandwidth the greater the cost. So, while video
conferencing may offer the broadest possibilities for communication, it may be
too expensive, or the infrastructure to support it may not be available. At the
same time, advancing development implies that bandwidth is constantly becoming
cheaper. In technologically advanced countries, demand for bandwidth is always
slightly in advance of its availability (we always want more) and in less
developed countries the bandwidth available is less than the current state of
the art.
ICT can also form a useful communication medium between
people with different sensory abilities. Coombs,
(1995)
shows how a blind teacher may be able to communicate with a deaf student
despite their mis-match of abilities thanks to email . While email is normally
used for communication between distant locations, it can also be used as a
means to local, face-to-face communication.
The world-wide web is a particular form of communication. It
has rapidly gained in importance such that it is almost becoming an essential
information source, not the least in education. The implication is that
exclusion from access to the web for any reason may become a handicap. There
are a number of possible causes of exclusion, probably the greatest of which is
economics – simply not being able to afford the equipment and connections. The
same physical and sensory disabilities that can affect any access to computers
can also hinder use of the web. Efforts are being expended on ensuring that
material on the web is accessible and that there are tools that facilitated
that access.
6. Implementation
There are a number of points that have to
be considered if the introduction and maintenance of ICT in Special Education
is to be successful.
Probably the most important is the need to train teachers
well. While it may often seem hard to acquire the equipment, there is no point
in doing that if it is going to lie neglected and unused, and it will only be
adopted if the people who might use it are confident in its use and convinced
of its usefulness.
There is also a need for support staff. While a well trained
teacher should be capable of diagnosing and repairing faults, that is not the best
use of a teacher’s time and technical backup should be available. Equipment
must be maintained and repaired.
Constant monitoring at all levels is also vital. This
applies to programmes of ICT use, so that the job is not over when the
equipment has been obtained and the teachers have been trained. They should not
be simply left ‘to get on with it’, but should be supported and monitored.
Similarly, individual students develop and change over time, so that it is
important not to assume that once they have a piece of equipment that their
needs will be met in perpetuity. As they develop and learn and as the
technology also improves, there should be re-assessment and updating as
appropriate.
Many of the uses that ICT has been put to have been
technology driven. That is to say that people have done things with the
technology because they can. At the same time, the power of the underlying
hardware has grown exponentially (Moore’s Law) making new applications
possible. To be led by the technology may seem inappropriate (particularly in
such a human-centred area as education) it is to a large extent inevitable. It
might seem appropriate to ask special education teachers what their needs are,
what the technology might do for them, but in practice it is hard for them to
envisage what might be possible.
An example is speech input. Until quite recently this might
have been seen as a facility that would be useful for non-literate children,
but dismissed as impractical. However with the increase in computing power
available, it has become readily available and new applications – including in
special education – are being found all the time.
It seems likely that there will be three areas in which the
role of ICT will grow:
• prostheses;
• standard
software;
• educational
software.
In the prosthetic role, as ICT is increasingly used by
people with disabilities to reduce their handicap, so it will be applied in
special education. This is likely to encourage integration in educational
systems where that is preferred. Examples would be the use of alternative and
augmentative communication (AAC) devices for face-to-face communication.
General applications (word processors, spreadsheets, databases etc) will
continue to be used, but with the added empowerment that they can give to users
with disabilities. There is some cross-over with the prosthetic role, so that,
for instance, a spelling checker that is useful to most users is invaluable to
some dyslexic writers.
Educational software currently takes the form of games and
programs designed to teach skills and concepts. Computer-aided learning is
still of a fairly general, simple drill-and-practice style. This can be most
valuable to children with learning disabilities. Deeper learning will become
possible as more intelligent software is developed – which incorporates a model
of the learner. Such models are difficult to build for the average student and
are even more challenging for learners who are so unusual that they are classed
as having special educational needs. Such software will emerge – but not for
some time yet. It will depend as much on better understanding of the psychology
of learning as on better technology.
7. Conclusions
Children with disabilities generally have
special needs with regard to their education. Some of those needs can be met by
information and communication technologies. As the technologies become more
advanced and more available there is a significant opportunity to improve the
quality of life of this disadvantaged group significantly.
Recommendations of the Meeting of Experts (Moscow, February 2000):
• UNESCO
and Member States should turn their attention to the fact that the real
break-throughs in special needs education could be provided by introduction of
ICTs in their learning, training and self-training;
• IITE
should become an international clearing house for the application of ICTs in
education, in particular special needs education, and promote exchange of
information and experience in this field. The examples of good practice of
application of ICTs in exclusive and especially inclusive education of people
with special needs in countries with different economic, social and cultural
environments should be found and disseminated;
• There
is a need for stocking existing data and knowledge bases on the use of ICTs in
special needs education and making it available for learners with special
needs, their teachers, teacher trainers, other educators, and decision-makers,
in particular through the IITE information facilities. Thus, for this purpose
an information sub-system ‘ICTs in Education for People with Special Needs’
within the framework of the IITE international project ‘ICTs in Education:
State-of-the-Art, Needs and Perspectives’ should be created. Specialized
questionnaires are necessary for its continual up-dating and replenishing;
• Education
modules on application of ICTs in special needs education, first of all such
modules for teacher training and re-training, should be developed within the
framework of the intersectorial UNESCO project ‘The Status of Teachers and
Teacher Education in the Information Society’ and included in the IITE
educational programme.
8. Glossary
AAC Alternative and augmentative
communication. Use of technology as a replacement for speech. The user
specifies utterances and these are (usually) translated into synthetic speech.
ASCII American Standard Code for
Information Interchange. Pronounced ‘Askey’. A standard data transmission code,
which is capable of representing 127 distinct codes, including all the Latin
letters (upper- and lower-case), the digits, 0 to 9 and punctuation characters,
such as brackets and full-stops. It also includes some unprintable control
codes for formatting and printer control (e.g. formfeeds to end a printed
page).
Asynchronous
communication
See ‘synchronous/asynchronous communication’.
See ‘synchronous/asynchronous communication’.
Bandwidth Broadly, the rate at which information can
be communicated along a channel. A high bandwidth interface can communicate a
lot of information quickly and is required for rich forms of information, such
as video. However, it will also be expensive. Simple information, such as text
requires lower bandwidth and is less expensive.
GUI Graphical user interface. A
computer that is controlled mainly through a visual form of interaction, based
on a screen, keyboard and mouse pointing device. Also sometimes referred to as
a WIMP interface (windows, icon, menu and pointer).
ICT Information and communication
technology. The term that has been coined to described the convergence of
technologies that process information (mainly computers) and those which
communicate it (networks).
Keyboard
emulation
This software generates output which is indistinguishable from keys pressed on a keyboard to other software (such as a word processor). In this way, someone who cannot physically press keys can nevertheless use standard, keyboard-based software through some other style of interaction (such as selecting letters from menus on screen, using a single switch).

Prosthetic
technology
Use of technology to reduce the handicapping effect of a disability. That is to say, using technology to perform actions that the non-disabled person might achieve without technology. An example is communication through an AAC device, in place of natural speech.

Screen
reader A piece of software which
effectively interrogates the contents of a computer screen and converts it into
a non-visual form. That form may be presented to the user in the form of
synthetic speech or braille.
Sip and
puff switch
A switch that is activate by a tube placed in the mouth. The switch has three states: neutral (off), one activated by blowing into it and the other by sucking on it.

Synchronous/asynchronous
communication
Loosely, synchronous communication involves both participants simultaneously. For instance, a telephone conversation requires both people to be on the line at the same time, to respond to each other in turn. Asynchronous communication does not require immediate responses. For example, an email message will be normally read and responded to the next time the recipient logs on to the system and not necessarily as soon as it arrives.

[1] Some writers refer to
information and communication technologies in the plural (i.e. ICTs). However, since the trend is towards the
convergence of the technologies, it seems appropriate to refer to them in the
singular; in time it will be too difficult to separate the communications
components from other aspects of the technology, so they might as well be
treated as one.
[2] Let us leave it to the
philosophers to argue whether information can be created. Is all information in some sense ‘out there’ waiting to be
discovered and codified, or can the truly creative mind spawn information that
is unique and novel?
[3] There can be some
debate as to whether illiteracy is a disability; one of the major objectives of
education is to impart literacy. However, there are cases in which a student
has a cognitive impairment which makes learning to read difficult or
impossible.
[4] A number of different
terms are used to describe this field, including Computer-Assisted Learning,
Computer-Aided Learning (both abbreviated to CAL) and Computer-Based Learning
(CBL)
[5] Synchronous also
implies real-time.
[6] Most communication can
be made to be 2-way, but some is inherently more conversational. For instance a
note in a newsgroup may generate a follow-up article, but nevertheless the
original note was essentially a one-way communication from the poster.
[7] Many-to-many also
implies the possibility of 1-to-1 and 1-to-many.
[8] Web pages may contain
high bandwidth material such as video clips or low bandwidth, if they are
simply text.
