Effect of Hearing Loss on Development
• Student is unlikely to use speech if hearing loss is– Pre-linguistic: before the development of language– Congenital: genetic or at birth
• Student is more likely to use speech and to speech-read if hearing loss is– Post-linguistic: after the development of language– Adventitious: caused by accident or illness

Meeting Learning Needs
• Make classroom visually friendly– Don’t speak with your back to students– Make sure everyone can see everyone else’s face
when students are speaking
• Include many visuals in lessons
• Encourage interaction among all students
• Understand that the sign-language interpreter is there for the student, not as a classroom aide
