Assistive technology can help students with disabilities in several ways: it can present educational materials in audio or visual formats to help master grade-level content; it can improve writing skills through tools like speech recognition software and concept mapping; and it can aid reading skills by reading text digitally or at lower levels. Different types of assistive technology address individual strengths and needs, such as speech recognition software for good speakers or text-to-speech for strong comprehenders. Software also provides feedback, focus, organization, stress reduction, and expression support.
