WHO IS AN AAC USER?
Anyone whose communication is adversely affected by an adversely affected by an impairment in speech,
language, cognition, and/or physical abilities.
In education who relies on AAC ?
• Learners with significant problems in communicating using speech.
• Variety of disability groups: Physical-, intellectual-, sensory-, Physical-, intellectual-, sensory-, multiple disability, autism, DAS
• Learners whose 1st language differs from the language of teaching and learning (classroom language)
Benefits for the teacher
• Ensures that reach children with different learning styles e.g visual learners.
• Helps children to concentrate on the activity being presented
• Ensures that you reach children in your class with different home languages, as there is always a visual clue to help learn new vocabulary being taught in the classroom
How is AAC used in Education?
Graphic symbols are used to help the learners:– Understand classroom rules and instructions– Understand content– Express what they know about what they have been
taughttaught
Understand Classroom rules
Understand an activity e.g. Brushing teeth
Understand the curriculum
� “Try and see” vs “wait and see”
� Facilitate language development(receptive and expressive)
� Provide children with power and control
Goals of AAC in Education
� Provide children with power and control
� Enhance social interaction
� Increase independence

Importance of Aided language Input
• No one would dispute that it would be very difficult to become fluent in a new language if your instructor seldom used the language in your presence.
• In the same way it is difficult for a non speaker to become proficient in AAC if other people never model using it in an interactive way.using it in an interactive way.
• Prospective AAC users must be provided with frequent examples of interactive, generative use to acquire any semblance of proficiency.
• If an individual is to gain AAC proficiency in using their AAC system others must begin to use their AAC system with them.
Aided Language Stimulation
• Strategy that helps learners to understand instructions, ideas and the curriculum better.
• Teacher points to, or shows picture symbols on a communication display as she speaks.
• So the learner is not just hearing the message but also can see it i.e. making the message visible.

AAC Myths and Legends
• Introducing AAC will stop someone from developing speech.
• Low technology before high tech.• Has a little speech so does not need AAC.• Too cognitively impaired to use AAC.• Too cognitively impaired to use AAC.• AAC will fix communication difficulties• Too young for AAC• Does not need AAC because can express basic needs
Common Clinician mistakes
• All or nothing mentality considering AAC only when individuals are not succeeding with speech.
• Fearing AAC will impede progress with speech (“make ittoo easy”) – communication should be easy!
• Limiting AAC options to basic needs – most of us • Limiting AAC options to basic needs – most of us want to tell people other things than “I need to go to thebathroom”.
• Too little intervention - giving someone a device orcommunication board and expecting them to use it.

Single message SGD’s

Ideas for single message SGDS
• Asking for “help”at computer, bathroom door, doing work• Place by door so student can say “go”• Attention getter (come here please)• Social (hi, how’s it going?, bye)• Making a choice partner presents choices verbally and
‐student hits VOD saying “That one‐I want that one”• Repetitive lines in stories• Delivering messages from home to school, from classroom
to the office• Requesting “more”• Book reading‐ “turn the page”

Ideas for multi message SGD’s
• Can have a separate overlay for a specific activity such as reading a book with generic comments. – “That’s funny/scary”. “I like that./don’t like that”– Read it again, etc)
• There are many stories that have either repeated text or • There are many stories that have either repeated text or just a few parts to the story. Goldilocks’, ‘who ate my porridge?’ etc.
High tech AAC
• Custom speech generating devices• Mainstream Technology
– Ipod touch/Ipad/– Android tablets– Android tablets– Laptops– AAC software and apps
High Tech AAC
Historically had• research and development before being released.• Vocabulary systems which reflected good practice• Accompanied by teaching materials and supportButBut• High production costs in a relatively small market • made the price inaccessible for most parents and
families.
Mainstream Mobile Devices for AAC
Mainstream mobile technologies
• Ipad changed the face of high tech AAC dramatically• AAC becoming consumer driven• More easy accessible and therefore AAC has become
more mainstream• There are now approximately 200 AAC apps on the • There are now approximately 200 AAC apps on the
itunes store there is also now alot of choice.• Anyone can now get a high tech AAC system for under
R10 000.

Questions to think about
• How do I know which mobile device or app to choose?• Are they worth the cost?• What DO they offer which mainstream speech
generating devices don’t.• What DON’T they offer which traditional SGD’s do?• What DON’T they offer which traditional SGD’s do?
AAC Apps
• Approximately 200 AAC apps (applications) on the itunesApp store
• 75% of apps are designed by people with no background in communication.
• Unfortunately many apps don't reflect good practice and research.research.
Example 1 • We know that category based AAC organisation slows
down communication and impedes the development of language and communication skills
• We have known this since the 80s • Despite this, 43 of the AAC Apps on the App store (at the
time of writing) are straight category based apps.
AAC Apps (Cont)Example 2 • We know that voice output encourages speech
development • Some app developers don't include speech in their AAC
Apps claiming that this is because speech output will impede speech developmentimpede speech development
Example 3• We know that providing an AAC system at all times and
modelling use of the system throughout the day in multiple situations leads to maximum language development and best outcomes
• In the instructions for several AAC Apps users are advised to allow access to the user only a couple of times a week until they become more competent
AAC Apps (cont)
• Good news is that there are some well designed apps which reflect good practice.
• And their numbers are slowly growing.• Too many apps still lacking a research base.

What the current research is telling us
Question asked: Was an evaluation conducted to determine the iPod/iPad would be the most appropriate communication system?
• YES- 54.4%• NO- 55.6%• NO- 55.6%• What does this tell us?– How do we know if it is the best system?– Feature/Skill matching?
– Need to match the student to the tech not the tech to the student NB NB NB
Coming back to previous questions
• How do I know which mobile device or app to choose?• Are they worth the cost?• What DO they offer which mainstream speech
generating devices don’t.• What DON’T they offer which traditional SGD’s do?• What DON’T they offer which traditional SGD’s do?
