Teachers in a Delaware district are using in-classroom amplification systems that allow students to hear the teacher and their classmates no matter where they are sitting. Teachers wear a wireless microphone, while students share a microphone, and their voices are broadcast through speakers. The systems have been shown to improve teaching and learning in classrooms nationwide. "If you're by the blower, the heating system, you're able to hear; whereas, before, it was always a problem," one teacher said. "No matter where you are in the room, the words being said, the concept being taught is right there, it's closer to you."
