The research evidence in this category is minimal and suffers, undoubtedly, from the same apparent “face validity” of the advantages in "response and navigation.” For students with physical and motor disabilities, the advantages of providing alternative tools and assistive technologies is so evident that researchers have not adequately researched their actual advantages for learning. The available research is also widely scattered in terms of the types of options provided (e.g., switch options, overlays, alternative keyboards, etc.). Scholarly reviews are devoted most often to highlighting best practices and comparative techniques.
