Hi April: We might first ask why students are disengaged in the first place? But let us assume that it is occuring as is most likely from time to time. Simple techniques can be effective, and sometimes more aggressive moves are needed. Simple would be like saying, " Bob, did you know that...blah, blah, blah? That command everyone listenting to hear the teacher and what Bob is going to say. Medium efforts might be to share a story or work related situation that has occured and students will re-focus - students like stories. More aggressive is like changing from lecture with PPT and whiteboard to small group discussion with class exercises. I call these change ups. Keeping variety in classes also helps keep attention of students. Change ups every 20 minutes would be ideal, but we can't always do it that frequently. BUt they'd stay focused! Regards, Barry
