A specific learning disability (LD) is in most situations a "hidden disability." Because there are no outward signs of a disability such as a white cane or wheelchair, people with an LD are often neglected when considering adaptive computer technology. However, many people with learning disabilities can benefit from mainstream and specialized hardware and software to operate a computer and further their academic and career goals.
Definitions and Terminology
A specific learning disability is unique to the individual and can appear in a variety of ways. It may be difficult to diagnose, to determine impact, and to accommodate.
Generally speaking, someone may be diagnosed with a learning disability if he/she is of average or above-average intelligence and there is a lack of achievement at age and ability level, or a large discrepancy between achievement and intellectual ability.
An untrained observer may conclude that a person with a learning disability is "lazy" or "just not trying hard enough." He may have a difficult time understanding the large discrepancy between reading comprehension and proficiency in verbal ability. The observer sees only the input and output, not the processing of the information. Deficiencies in the processing of information make learning and expressing ideas difficult or impossible tasks. Learning disabilities usually fall within four broad categories:
- Spoken language - listening and speaking.
- Written language - reading, writing, and
spelling.
- Arithmetic - calculation and concepts.
- Reasoning - organization and integration of ideas and thoughts.
A person with a learning disability may have discrepancies in one or all of these categories. The effects of an LD are manifested differently for different individuals and range from mild to severe. Learning disabilities may also be present along with other disabilities such as mobility or sensory impairments. Often people with Attention Deficit Disorder/Attention Deficit Hyperactive Disorder (ADD/ADHD) also have learning disabilities. Specific types of learning disabilities include:
- Dysgraphia - An individual with Dysgraphia has a difficult time with the physical task of forming letters and words using a pen and paper and has difficulty producing legible handwriting.
- Dyscalculia - A person with Dyscalculia has difficulty understanding and using math concepts and symbols.
- Dyspraxia - Language comprehension of a person with Dyspraxia does not match language production. She may mix up words and sentences while talking.
- Non-verbal Learning Disorder - A non-verbal Learning Disorder is demonstrated by below-average motor coordination, visual-spatial organization, and social skills.
- Dyslexia - An individual with Dyslexia may mix up letters within words and words within sentences while reading. He may also have difficulty spelling words correctly while writing; letter reversals are common. Some individuals with Dyslexia may also have a difficult time with navigating and route finding using right/left and/or compass directions.
Accommodations
Assistive and adaptive technology does not
"cure" a specific learning disability. These tools compensate rather than
remedy, allowing a person with an LD to demonstrate their intelligence and
knowledge. Adaptive technology for the person with an LD is a made-to-fit
implementation. Trial and error may be required to find a set of
appropriate tools and techniques for a specific individual. Ideally, a
person with an LD plays a key role in selecting her technology. She should
help to determine what works and what does not. Once basic tools and
strategies are selected, they can be "test driven," discarded, adapted,
and/or refined.
Following are descriptions of some computing tools that have been used effectively by individuals with specific learning disabilities. This list is not exhaustive and should not limit the person with an LD or the adaptive technology practitioner from trying something new. Today's experimental tinkering could lead to tomorrow's commonly used tool.
- Word Processors
Computer-based accommodations for Dyslexia may not require specialized hardware or software. For example, a person with Dyslexia can benefit from regularly using built-in word processor features such as:
- Spell checking
- Grammar checking
- Font size and color changes
These built-in features are relatively low priced tools that, when
used together, provide an alternative to handwritten expression. The use
of spell checkers can allow the person with learning difficulties to
remain focused on the task of communication, rather than getting bogged
down in the process of trying unsuccessfully to identify and correct
spelling errors. Many word processing programs also include tools for
outlining thoughts and providing alternative visual formats that may
compensate for difficulty in organizing words and ideas. Additionally,
color-coded text options and outline capabilities present in many word
processing programs are useful tools for those with difficulty sorting and
sequencing thoughts and ideas. Additionally, color-coded text options and
outline capabilities present in many word processing programs are useful
tools for those with difficulty sorting and sequencing thoughts and ideas.
A word processor can also be used as a compensatory tool for a person with Dysgraphia. Use of a keyboard may be a viable alternative for an individual who has difficulty expressing his thoughts via handwriting.
- Reading Systems
An individual who can take in information through listening much
better than by reading may benefit from using a reading system. These
systems allow text on screen (document, web page, or email) to be read
aloud through the computer's sound card. A scanner and Optical Character
Recognition (OCR) software (e.g., Freedom Scientific's WYNN or Kurzweil
3000) adds the feature of reading printed text. Hard copy text is placed
on the scanner where it is converted into a digital image. This image is
then converted to a text file, making the characters recognizable by the
computer. The computer can then read the words back using a speech
synthesizer and simultaneously present the words on screen.
Reading systems include options such as highlighting a word, sentence, or paragraph using contrasting colors. If desired, the reader may elect to have only one word at a time appear on the screen to improve her grasp of the material. Increasing the size of the text displayed on the screen as well as changing text color can increase reading comprehension for some people with specific learning disabilities.
- Concept Mapping
Some individuals have difficulty organizing and integrating thoughts and ideas while writing. Concept mapping software allows for visual representation of ideas and concepts. These representations are presented in a physical manner and can be connected with arrows to show the relationship between ideas. These graphically represented ideas can be linked, rearranged, color coded, and matched with a variety of icons to suit the need of the user. Concept mapping software can be used as a structure for starting and organizing such diverse writing projects as poetry, term papers, resumes, schedules, or even computer programs.
- Phonetic Spelling
People with Dyslexia often spell phonetically, making use of word prediction or spell checking software less useful. Devices (e.g., Franklin Electronic Dictionary ™) or software (YakYak ™) that renders phonetic spelling into correctly spelled words may be useful tools.
- Word Prediction
Spelling words correctly while typing can be a challenge for some people with Dyslexia. Word prediction programs prompt the user with a list of most likely word choices based upon what has been typed so far. Rather than experiencing the frustration of remembering the spelling of a word, he can refer to the predictive list, choose the desired word and continue with the expression of thoughts and ideas.
- Speech Recognition
Speech recognition products provide appropriate tools for
individuals with a wide range of learning disabilities. Speech recognition
software takes the spoken word via a microphone and converts it to
machine-readable format. The user speaks into a microphone either with
pauses between words (discrete speech) or in a normal talking manner
(continuous speech). The discrete product, although slower, is often the
better choice for those with LDs because errors can be identified as
they occur. Making corrections after the fact using continuous speech
requires proficient reading skills. Speech recognition technology requires
that
the user have moderately good reading comprehension to correct the
program's text output. Because many people with LDs have reading problems,
speech recognition is not always an appropriate accommodation.
- Organizational Software/Personal Information Managers (PIMs)
Organizing schedules and information is difficult for some people
with dyslexia or a non-verbal learning disorder. Personal Information
Managers (PIMs) such as a Palm Pilot ™ or Casio ™ or
organizational software such as Microsoft Outlook ™ or Lotus
Organizer ™ can accommodate these disabilities. Such tools can be
helpful to those with LDs by providing a centralized and portable means of
organizing schedules and information. The cues provided by these tools can
assist keeping on task and may help provide visual alternatives to
represent what work needs to be done and what has been accomplished.
However, they may also put early learners at a disadvantage by requiring
yet another program and interface to learn and remember to use.
Individuals may lack the discipline/attention skills to regularly check
the application/device.
- Talking Calculators
A talking calculator is an appropriate tool for people with Dyscalculia. The synthesized voice output of a talking calculator provides feedback to the user that helps them identify any input errors. Additionally, hearing the calculated answer can provide a check against the transposition of numbers commonly reversed in reading by people with Dyslexia or Dyscalculia.
- Low Tech Tools (Post-It Notes, Highlighters)
Not all assistive technology for people with LDs is computer-based. The use of common office supplies such as Post-It Notes™ and highlighter pens provide elegantly simple means of sorting and prioritizing thoughts, ideas, and concepts. Often, tools of one's own making provide the most effective and comfortable accommodations for learning difficulties.
