Assistive technology refers to any equipment or device that helps students with disabilities function independently in the classroom. This includes simple devices like pencil grips as well as complex technologies like motorized wheelchairs. The Individuals with Disabilities Education Act requires schools to evaluate students' needs and provide assistive technologies if deemed necessary by a student's IEP team. Examples of assistive technologies discussed in the document include FM systems to help hearing impaired students, video magnifiers with text-to-speech for visually impaired students, talking spell checkers for learning disabilities, and oversized trackball mice for physical disabilities.
