This document provides instructions for observing classroom use of augmentative and alternative communication (AAC) methods. Teachers are instructed to check boxes when specific unaided and aided communication approaches are used, either every time a new topic is introduced or at fixed time intervals. The goal is to collect data over a week to analyze which methods are used most and determine if adapting AAC use could better meet students' needs. Boxes are provided to check uses of unaided gestures and signs, low-tech tools like pictures and symbols, and high-tech devices from single-message to complex computer systems.
