Direct questions for the hearing-impaired student to the student, not the interpreter. Interpreters do not participate in the class and cannot speak or think for the hearing-impaired students. Understand that the interpreter may need to adjust the lecture pace and sometimes it may be necessary for professors to adjust to the pace of the interpreter. So that the student can maintain eye contact with both professor and interpreter, understand that the interpreter will generally sit to the left or right of the professor facing the class. Assist with any needed classroom re-arrangements so that the interpreter will be sitting in good lighting.
Sign language is a concept-based language.
There may not be a specific sign for specialized jargon . Usually, the interpreter will have to fingerspell specialized jargon using a manual alphabet. Writing any jargon on the chalkboard or giving a list of words to the interpreter before class can be very helpful. Hearing-impaired students find it difficult to continually shift eye contact between the chalkboard and the interpreter when professors simultaneously lecture and use chalkboard demonstrations. When lighting is reduced, it is important to make sure there is still sufficient lighting for the interpreter to be seen.
