Overview• PurposeTo determine if sound field reinforcement technology (teacher microphones)
enhances teaching and learning
• Phase I (2009-2010) Validation of Independent Research Results5 Schools – 2-3 classroom microphone systems per schoolSubstantial positive benefits reported
• Phase 2 (2010-2011) Product Testing & Evaluation of Large Scale Implementation5 schools – extended to 10-12 classroom microphone systems per school7 new schools – microphone system in every classroom
