For more experienced AAC users, words that may not be on their immediate communication pages can be accessed through the dictionary pages. Involving the AAC user to the fullest extent possible when completing a vocabulary gathering task for page creation is another powerful way to introduce new words. This can be integrated into everyday educational and therapy activities. When looking for words and messages to include on a communication page, allow the AAC user to choose words or symbols that will be placed on their page. This provides an excellent opportunity to teach new words and symbols.
Morphology refers to the rules for building and modifying the meaning of words.
Research shows that AAC users often do not have the symbols necessary to indicate morphological changes or have not learned the rules of morphology with adequate opportunities to practice. There are several low and high tech methods for providing access to different grammatical word forms. For example, many high-end voice output AAC devices allow individuals to have access to grammatical morphemes and the ability to change word forms. By providing these tools and providing functional instruction, augmented communicators can be well on their way to expanding their language. It is necessary to provide modeling in functional situations.
