Additional Strategies In addition to consistent vocabulary, customization of the system was vital. It may seem that the sound patterns we used are not an exact match for CoreScanner now. We found it impor- tant to change the scan patterns, so back was always the first choice. This was done so that in the event a block was selected in error; it would save time for the user should they need to go back, rather than having to scan through nine icons before being able to exit the block. Additionally, the alphabet was reorganized so more frequently used letters required fewer switch hits to access (see Image 5). New alphabet songs were created to teach the new order of the letters. Songs were also made for each of the letter blocks using the same drum and cymbal sound patterns as well as lyrics to learn the name and sound of the letters during literacy instruc- tion. A low-tech board to replicate the system was used to supple- ment teaching vocabulary within the blocks (see Image 6). Eight large 12” x 12” cardboard pieces were used to make a low-tech board. One side of the 12’ x 12” removable piece was the corner- stone word, and the other side contained 4”x 4”removable icons. These low tech pieces were used during teaching activities for language learning such as pronouns; he, she, it or concepts; big,
little, fast. We also used the larger icons when listening to “Name That Tune” songs.
Other Devices This strategy has been used with multiple students with a variety of systems. CoreScanner by PRC was selected specifically for Corinne to access through auditory scanning when we started this project. CoreScanner is a robust language system and with customization is an excellent choice for auditory scanners. We have had great success with this strategy using CoreScanner with Corinne as well as other students. Sometimes we get students that already have a device in place. When this happens, we do our best to use the device that user has and try to make it work so that they can have access to a robust language system while still considering the access needs. This often means that vocabu- lary, pages and folders need to be made from scratch and scan- ning patterns need to be programmed. It can be a significant time commitment upfront to make a system work effectively to meet the needs of auditory scanners. Additionally, consideration must be given to the additional equipment needed to connect switches to iPads and computers as well as the setting up switch control or in-app scanning settings. Each system has pros and cons for switch users.
