Visual issues can be a hidden Visual issues can be a hidden problem…problem…
A large percentage of children with multiple disabilities are visually impaired
“Over 40% of the brain is devoted to visual function, so it is not surprising that a large portion of children with damage to the brain have visual problems.” *
* Dr. Christine Roman-Lantzy, Cortical Visual Impairment, AFB Press, 2008, pg. 10.

Impact of Vision Loss on Impact of Vision Loss on LearningLearning
Limits ability to learn incidentally from the environment
About 80% of what children without visual impairments learn is through visual cues *
The other senses do not fully compensate – the only other distance sense, hearing, does not give long-lasting information that can be re-examined easily

Using a Symbol System for Using a Symbol System for Communication & LiteracyCommunication & Literacy
Ultimate = print/braille & spoken language
Common alternative = symbol or photograph based system
Many MD/VI students struggle with symbols

Common Problems Using Common Problems Using SymbolsSymbols1. Materials with symbols are
visually complex2. Learning medium isn’t
considered – incorrect symbol type is chosen

Problem 1 – Symbols are Problem 1 – Symbols are ComplexComplex
The drawings can be very abstractThe parts necessary to determine
exact meaning can be very small1 1/2” size typically used is usually too
smallMultiple colors can be cluttered &
distractingRemember, students usually can’t read

Better ways to use Symbols –Size & Better ways to use Symbols –Size & GlareGlare
Use symbols large enough to correctly discriminate – my standard is 3” square
Size is even more important when the student has limited motor skills
Consider lighting & glare ◦Check glare at kid’s eye level◦Reposition materials/student◦Glare from laminating film◦CRITICAL for computer/device screens

Problem 2 – Correctly Consider Problem 2 – Correctly Consider Learning MediumLearning Medium
Learning Medium = what sensory channel is used for learning◦Vision, tactile, auditory
Usually a primary and secondary medium
Learning Medium determines the type of symbol system that is needed
TVI and Speech must work together

CVI Challenges with 2-D imagesCVI Challenges with 2-D images
Photos or symbols are not recommended for children with a CVI Range score less than 6 due to visual processing issues *
Teach more complex symbols over time as CVI score improves

Classroom AT tools for Literacy and Communication need to be used differently for MD/VI students
Individual visual functioning must be considered for each student – TVI’s area of expertise
Visual and motor needs are hard to separate - coordination between the TVI, SLP, OT, and PT is needed

SummarySummary
The TVI is a critical element in a team of specialists who collaborate regularly
Selecting the appropriate symbol system is critical for communication and literacy to be accessible
Changing how we use devices and set up the environment is key to helping students with MD/VI be successful communicators
