This video discusses the importance of comprehension in demonstrating an understanding of what is being read or said. The speaker suggests that before students can answer questions, they need to practice asking questions and learn about “Who” questions like “who” and “where”. The video explains how to use “Who” questions with AAC to work on these skills, including asking and answering questions related to a story. The speaker encourages the use of high or low tech voice output or printed options to assist with communication. They also suggest discussing aspects of a story such as the setting, vocabulary, and characters to improve comprehension. The goal of the activity is to expose the child to different aspects of a narrative, not to test them. The speaker recommends letting the student pick which “Wh” question they want to ask and modeling how to navigate to the correct category or word.
