Which of the following is a type of direct selection tool?

A dowel is indeed a type of direct selection tool because it is a physical means that an individual can directly use to make a selection or communicate their choice. In assistive communication contexts, direct selection refers to methods where the user physically interacts with a communication device or method, such as pointing, touching, or using a tool like a dowel to select an item from a grid or board.

In contrast, the other options involve indirect selection methods or prompts. Auditory scanning and partner directed scanning require an intermediary process where selections are made based on the auditory or visual prompts provided by another person or device. Visual prompts are supportive cues to assist in making selections but don't represent a direct means of selection as the dowel does. Thus, the dowel stands out as a clear tool that allows for autonomous and immediate communication through direct interaction.
