I'd like to address how important I feel the teaching environment is. I know myself if a room is cluttered or unkempt I do not concentrate as well. Other things that should be monitored are the lighting and the temperature of the room. These things are as important for staying focused as are a good nights rest. I like to reevaluate my room for clutter and cleanliness at least once per day. If I notice a student adjusting looking like they are getting tired the first thing I think of is whether the heat in the classroom is too high. If a student appears to be squinting to see a powerpoint perhaps the lighting needs adjustment. In order for our students to absorb information the topic presentation should be the only thing on their mind. Atmosphere control can assist with this concern.
