If new vocabulary cannot be presented in advance, write the terms on paper, chalkboard, or an overhead projector. Repeat questions or statements made from the back of the room and point to the person speaking. Remember that deaf and hard of hearing students are cut off from whatever happens outside of their visual area. If a student doesn't understand you, rephrase your message instead of repeating it in a louder voice. Use short sentences.
Writing is a good way to clarify important points.
Approximately thirty percent of all spoken sounds are visible on the lips. Many deaf people learned English as a second language and may have some English-language challenges. Make sure lighting makes your face clearly visible. If you plan on showing films or videos, please inquire as to the availability of a captioned or close-captioned version. Ask the student if you have questions or need information.
