TouchChat is an Augmentative and Alternative Communication (AAC) app that supports communication for non-verbal/minimally verbal students. This tool customizes picture-based symbols and voice output. The layout allow for both core words and academic/content specific vocabulary. For math and science instruction, TouchChat can be programmed with subject-specific pages for example, science experiment steps (measure, mix, record, observe), math terms (add, subtract, equal, shape names, fraction), or sentence frames (The result is, I predict).

How it enhances language development/communication skills.
Allowing students to use TouchChat during math/science instruction enables them to:
Identify vocabulary.
Respond to questions during lessons.
Identify objects.
Describe observations.
When students use this tool, it allows them to share their thoughts/ideas, answer questions, and engage in discussions in class. This allows students to develop their language skills, expressive/receptive communication, and vocabulary within academic settings. For example, their speech improves and they learn new words. Students will also receive instruction that embeds language modeling, teachers will show students how to use AAC to make comments, describe observations, and ask questions. The more consistently they use their device, the more autonomy in communication they will gain, which will reduce frustration and support social interactions. Additionally, using this tool will promote literacy skills, as students will be able to combine symbols and spoken words to connect oral and written language.

How it supports instruction and collaboration.
Teachers, paraprofessionals, and speech-language pathologists (SLP) can work together to add words that match what students are learning in math and science. Collaborating during the planning process helps keep communication consistent across different settings. Teachers can plan lessons that incorporate the AAC device, SLPs will program/maintain vocabulary relevant (math/science units), and paraprofessionals will model the AAC use. Additionally, TouchChat lets teachers assess their student's understanding. When students use their devices to share answers, teachers will use the responses to make adjustments that will make lessons more effective, inclusive, and informed.
