Based on gains in student achievement and teacher effectiveness many school districts across the country now include audio reinforcing technology in every classroom. Most of us can relate to conferences in large hotel rooms where the presenter fumbles with a wireless microphone questioning “Can you hear me now?” until someone in the back of the room acknowledges the volume is satisfactory. We have all been frustrated when a member of the audience states a question that no one hears and the presenter answers without repeating it. As adults we ask for presenters to speak up, adjust equipment or repeat the question because we are there for a purpose and the information is important to us.
Though the audience in a school classroom knows the information is just as important, the confidence and skill set needed to speak up and ask the teacher to do anything different is not likely to exist. If there is background noise, if the teacher speaks in low tones, speaks while facing the board, has an accent or talks fast, or if some children are hearing impaired; it is possible some students will not receive the information. Unlike adults, it is unlikely the child will complain they
cannot hear or make a request for the teacher to repeat information they did not hear.
