Make sure you have a deaf student's attention before speaking. A light touch on the shoulder, a wave, or other visual signal will help. Look directly at a person with a hearing loss during a conversation, even when an interpreter is present. Speak clearly, without shouting. If you have problems being understood, rephrase your thoughts.
Writing is also a good way to clarify.
Make sure that your face is clearly visible. Keep your hands away from your face and mouth while speaking. Sitting with your back to a window, gum chewing, cigarette smoking, pencil biting, and similar obstructions of the lips can also interfere with the effectiveness of communication. Modes of Communication Not all deaf students are fluent users of all of the communication modes used across the deaf community, just as users of spoken language are not fluent in all oral languages. Fingerspelling is the use of the manual alphabet to form words.
