Introduction
This Unit covers basic ICT in the context of
pupils with a visual impairment. The different media (visual, auditory and
tactile) are explained, and their role in developing initial listening and the
tactile skills of pupils is considered.
After introducing underpinning concepts, a
number of scenarios are presented and explained, which demonstrate effective
use of ICT for pupils in a range of circumstances.
Pupils with a visual impairment can make use of
ICT such as overlay keyboards, talking word processors and touch screens to
develop fundamental skills and concepts. These are the building blocks that can
be used by older pupils to be independent and effective learners.
Both this Unit and
Unit 10
ICT for visually impaired pupils cover a similar range of
underpinning concepts. However, the latter Unit also considers the technologies
that pupils can use to study independently such as note-takers, text scanning
systems and Internet access. It is anticipated that teachers will choose
between these Units as appropriate to their pupils needs and their own
professional development plans.
Visual impairment
Visual impairments in pupils take many forms;
for example, pupils may be born blind, or may lose their sight as a result of
injury or slow deterioration; in some cases the visual impairment is one aspect
of multiple disability.
In these Units the term visual
impairment is used broadly to refer to both blind and partially sighted
pupils.
Pupils are often grouped according to the
classifications blind or partially sighted, but these two classifications give
little indication of levels of functional vision. The vast majority of pupils
have some useful sight; the two key measures of vision, which give information
concerning the impact of the visual impairment, are:
- acuity how sharply and in how much detail the
object is seen
- field the area seen by the pupil as they look
straight ahead
Each childs eye condition is quite
specific and the impact it has on their learning is unique. How this functional
vision is utilized will determine the impact it has on their development.
Much information is gathered concerning the
pupil and assessments often take a multidisciplinary approach. Input is
gathered concerning the childs functional vision, mobility needs,
psychological functioning and curriculum access needs, including the
possibility of utilizing technology. Once gathered, this information must be
collated to evaluate the overall effectiveness of the organization of the
learning environment, make recommendations for the strategic implementation of
specific strategies to afford greater independence when accessing the
curriculum and, at the same time, provide further tools to complement existing
teaching programs.
By the end of this Unit, participants will
- have an understanding of what basic ICT means in the
context of pupils with a visual impairment
- have an understanding of the key issues involved in
making appropriate ICT choices for pupils with a visual impairment
- be aware of the complex and unique needs of pupils with
a visual impairment in relation to technology intervention
- be aware of possible basic technology solutions to
implement within the learning environment of pupils with a visual impairment
- be aware of ICT-based activities to support pupils
progress towards identified teaching objectives
- have an understanding of the contribution technology
makes to the assessment of learning, being able to make decisions concerning
its appropriateness.
Adapt the input medium through the use of tactile or
visual labels
Alter the labels on the input device, for example using
keyboard stickers or adapting the labels on a programmable robot.
See Scenario 1
Use a programmable floor robot
Develop spatial awareness, positional concepts and improved
use of functional vision through the use of a programmable floor robot.
See Scenario 1
Use a low vision aid to access printed materials
independently
Control the size, contrast and position of an image through
the use of a magnification system. (CCTV)
See Scenario 2, Example 2a
Use a talking word processor with on-screen word
banks
Adopt a multi sensory approach to support emergent literacy
skills through speech output and enlarged on screen text.
See Scenario 2, Example 2c
Configure the screen to allow a pupil to make the most
use of their functional vision
Configure toolbars, screen presentation, enlarged mouse
pointer and text presentation size to suit the individual visual needs of the
pupil.
See Scenario 2, Example 2c
Configure speech output options to respond to a
pupils preferences
Alter the voice, pitch, speed, prosody, character and word
or sentence echo to suit the preferred needs of the pupil.
See Scenario 2, Example 2c
Set up and configure a Brailler with additional
peripherals, keyboard and printer
Provide a Braille production system, which provides hard
copy Braille, has Braille and QWERTY input and has the flexibility
to provide speech output for people with and without Braille skills.
See Scenario 2, Example 2d
Design and create tactile overlays
Use equipment to produce tactile diagrams to support the
demands of the curriculum through the use of specialist equipment.
See Scenario 2, Example 2e Scenario 3, Examples 3a, 3c, and
3d
Design and create on-screen grids (with / without switch
access)
Develop tailor made and differentiated grids to support a
breadth of curriculum requirements and access needs, altering content,
presentation and input method.
See Scenario 3, Example 3a
Use authoring software to develop appropriate curriculum
materials
Use framework packages such as PowerPoint, IntelliPics and
SwitchIt! Maker to design differentiated materials to develop appropriate
curriculum materials.
See Scenario 3, Example 3b
Use technology to support the development of eye-hand
coordination
Use commercially produced or individually tailored
applications to assess and develop eye-hand coordination, making adaptations
where appropriate.
See Scenario 3, Example 3e
Use ICT to support the development of keyboard
familiarity and keyboard skills
Use PC-based exercises to develop keyboard familiarity and
skill through the enhancement and adaptation of the screen presentation and
speech output.
See Scenario 3, Example 3f
Use key strokes as appropriate to replace the need for
positional mouse clicks
Develop and awareness and understanding of the use of key
strokes to replace the need for positional mouse clicks where movement of the
pointer inhibits visual tracking and location.
See Scenario 3, Example 3g
