Physical Access to ICT
When thinking about the kinds of ICT resources for pupils
with special needs the first consideration should be the physical
access to the equipment and then the effective use of that
equipment. This is influenced by several factors including:
Physical Stability and Positioning
Communication
Cognition and Learning
Physical Stability and Positioning
For those who have some
kind of physical difficulty, for example; dyspraxia, Cerebral
Palsy, types of muscular dystrophy or other conditions, there
may be issues with balance and /or stability. The objective
is to enable access to the equipment by overcoming any stability
problems.
Correct seating and postural stability is the foundation
for comfortable and efficient use of any equipment. Imagine
trying to operate the mouse or touch the screen accurately
while sitting on a large ball with no firm footing. This would
make using the equipment more difficult because the brain has
to process and manage all the signals from the body and compensate
and correct movement at the same time as concentrating on the
task and controlling the equipment. When coordination has not
become fully automated or is interrupted because of a person’s
physical difficulty, the effort of controlling the extra movement
can take up more of the “working memory” which
is also needed to cope with the processing of the instructions
and information related to the task.
In general stability will be improved with:
- Appropriate seating and foot, back and arm rests where
necessary.
- The type of furniture. Many tables, or shelving on which
computer technology is placed is not conducive to ease of
access and
precludes the above happening. Monitors can be placed on
extendable arm brackets if the table cannot be raised or
lowered.
- The mounting and position of the monitor
- The correct input device and its positioning for the user
A user’s reach and range of movement along with the
quality and consistency of that movement is also linked with
stability. Some users may use an access device other than a
mouse and mounted as a head, foot or mouth switch for instance.
Equipment needs to be placed in a position that allows the
user to manipulate it with as much control as possible without
over-stretching, extension or flexion of limbs or joints.
A Physiotherapy and Occupational Therapy advice needs to
be obtained to ensure that proper seating, furniture and adaptations
are recommended for those with Physical Disabilities and this
advice should be sought by the school as well, especially where
disability carries a risk of developing scoliosis of the spine
and contractures of the joints.
Types of Access Equipment
This is not an exhaustive list and suppliers such as SEMERC
and Inclusive Technology have on line catalogues of a full
range of access devices and solutions. MGL consultancy can
also provide advice and assessment for schools and individual
pupils who need to review their ICT Access, by emailing alastair.fielden@mglworld.com
Alternative Mouse inputs:
Touch Pad
Various Switch types
Roller Ball
Joystick
Touch Screen or Monitor
Eye track and head pointing devices
Alternative Keyboard inputs:
Voice recognition software Various sized keyboards such as Big Keys, Small keyboards
On-screen keyboards – Win Xp has an in-built one in
the Accessories panel
Concept keyboards such as Intellikeys To Teach typing skills or Not?
One issue that is sometimes hotly debated is whether to “teach” formal
keyboarding skills in this context. Adding another layer of
physical manipulation, and thereby learning, in the case of
pupils with motor control and processing difficulties, by requiring
them to physically learn the placing of the fingers on the
Keyboard using the finger isolations and targeting the keys
accurately, can work against success and be a cause of frustration.
If the user is not going to type, use an on-screen keyboard
or other form of letter by letter input device then this is
a moot point. However, keyboard familiarity can be taught away
from the computer with a keyboard game such as Keyboard Crazy
from www.keyboardcrazy.co.uk/
Communication The area of Communication covers verbal, non-verbal, signing
and the use of symbols, such as REBUS, or pictures such as
PECS (Picture Exchange Communication Symbols). Where there
is a difficulty with Communication then referral to the Speech
and Language Therapy service should have been made. Where it
is suspected that a specific learning difficulty such as Dyslexia
is may be present then a referral for a specialist assessment
would be needed. MGL Consultancy is able to provide assessment
for Dyslexia.
A difficulty with communication can often be a main source
of stress and frustration, which can sometimes show itself
as:
- A general avoidance of language-based activities – Could
also show in behavioural outbursts
- Excuses for not reading and /or writing
- Passive communication, relying on others to communicate
for them,
- Reduced written output either because of a lack of physical
stamina, or problems with language processing and output
There are a large number of ICT resources designed for developing
and aiding communication, reading and writing. As a guiding
principle for choosing software and tasks on the computer the
following will be helpful:
- Speech Feedback; The program speaks the letter, word, phrase
or whole page text
- Age and Reading age appropriate text
- Clear uncluttered screen layout
- Writing frames and structure to help learn spelling conventions
and grammatical structure
- With the flexibility for symbol or picture support should
this be needed
Cognition and Learning
This area is likely to be addressed by the school through
the educational psychology assessments and the advice that
results from this. In general terms, the areas of cognition
that can influence the choice of equipment, software and tasks,
need to take account of a pupil’s:
- Attention Control
- Concentration
- freedom from distractibility
- Sequencing and Processing instructions and information
along with formulating and producing a response
- Memory and recall, digit span
- Main strength for information gathering; Visual, auditory
or kinaesthetic.
It is worth remembering that when pupils with such learning
needs are using ICT it is the QUALITY of the activity rather
than the QUANTITY of time at an activity that is important.
The pupils’ ability to remember the task, recognise the
target and work through the steps of the task, while navigating
the program and controls can influence the complexity of the
task and speed at which the user can accomplish it.
One of the benefits of using ICT as a tool in the learning
process is that it does not “criticise” the user.
There is a correct or incorrect response from the program which
is non-judgemental. Some pupils enjoy the “rewards” built
in to some of the programs. An appropriate program, used effectively,
can:
- Remove or at least reduce a lot of the stress that pupils
often associate with language work
- Speech feedback and visual prompts can take away the guess-work
of spelling involved
- Structured activities and frameworks can guide the user
through the production of a piece of text
- Word prediction software also reduces an amount of physical
typing needed and can help to speed up output
- An adult working with the pupil can use the computer as
an intermediary and reduce the potential for conflict “what
is the computer wanting you to do now?”, rather than, “Now
I want you to do..?”
- The formatting available and the printed output looks neat
and tidy and this presentation can help the pupil’s
self esteem.
When working with pupils at a lower level of ability then
the general principles of differentiation apply. When differentiating
the task through ICT build in time to become familiar with
the program and the task.
