Hearing Impairments
Request and encourage student input on how to best accommodate the student's learning needs.
Provide a sign language interpreter, real-time captioning, and/or an FM system.
Use visual aids to explain concepts to the student.
Give assignments, lab instructions, and demonstration summaries in writing.
Use electronic mail for class and private discussions.
Face students with hearing impairments so that they can see your lips. Speak clearly. Repeat questions or comments from others.

Learning Disabilities
Request and encourage student input on how to best accommodate the student's learning needs.
In activities that require writing, consider computer accommodations. Use built-in word processor features such as the spelling checker and grammar checker. For more information, consult the video presentation and publication Working Together: Computers and People with Learning Disabilities.
Talking calculators may be appropriate for some students. For information on talking calculators, consult Independent Living Aids.
Consider reformatting documents to minimize clutter and/or providing materials in large-print format. Ask the student if this would be helpful.
Allow extra time for assignments and exams. Provide alternative testing arrangements.
Minimize distractions as much as possible. Keep the classroom door closed, and seat the student with attention deficits away from windows and other distractions.
Provide clear and specific instructions. Break down larger tasks into smaller chunks, and provide directions for only one or two activities at a time.
Consider the needs of students with disabilities during lab orientation and lab safety meetings.
Assign group activities in which all students take responsibility and contribute according to their abilities.
Use multiple formats—oral, written, visual, tactile, electronic—for instruction and demonstrations.

Mobility Impairments
Request and encourage student input on how to best accommodate the student's learning needs.
Assure that classrooms and labs are in wheelchair-accessible locations.
Assure that there is enough space between lab tables to allow for wheelchair access.
Consider providing a note taker.
Support the student's use of a computer equipped with a special input device (e.g., voice input, Morse code, alternative keyboard) whenever appropriate. For more information, consult the video presentation and publication Working Together: Computers and People with Mobility Impairments or the AccessSTEM Knowledge Base.
Because this unit involves manipulation of small objects, make adjustments for a student with upper body mobility impairment or fine motor coordination issues; sometimes working with a partner is effective. Also, consult lab design recommendations for students with mobility impairments at AssisTech.
