A computer with voice output software is an appropriate accommodation for students with learning disabilities. Consult the video presentation and publication Working Together: Computers and People with Learning Disabilities and the AccessSTEM Knowledge Base.
Consider reformatting documents to minimize clutter and/or providing materials in large-print format. Ask the student if this would be helpful.
Provide clear and specific instructions. Break down larger tasks into smaller chunks, and provide directions for only one or two activities at a time.
