Visual cues are also excellent for classroom management as well. Some examples of visual cues (this is the benefit for those who may not be be aware of what kinds of visual cues can be used):
*Yes - any object can be used to indicate who is doing the speaking and whose turn it is. I found this not only helps the deaf student, but the hearing classmates as well since it helps them with turn-taking skills, listening skills, and learning to look for information.
*if using a FM system, passing the microphone from speaker to speaker is important (of course, the kids will need to learn how to handle it properly and carefully, etc.)
*switching on the lights for attention
*all kids raise hands to indicate it is time to stop talking/working/playing and look for the teacher (kids who are engaged will see a kid with his hand raise, and then automatically know it is time to stop, raise his hand, and look for the teacher
*use a visual timer (I use the one on the Smartboard) to indicate it is time to stop and transit
*use visual color code system or signs to indicate a message (for example, I have a large sign with a STOP sign - when it is time for the kids who are playing outside to stop playing and line up, I put up the sign. This helps alert them that the "bell has rung")
*when in a group with kids, and one kid starts talking - the teacher needs to use some kind of cue to indicate WHO is talking (pointing at the kid, or using the sign for look at the kid (two fingers pointing at the direction of the speaker/signer)
*the teacher also should indicate when someone speaks on the intercom /PA system
