I would arrange my students desks in a cirlce. That way I would always be the center of attention. In my opinion, this would make learning easier. I would also have areas in my room designed for different purposes. For example there would an area for quiet time where a student could read, do homework, or even relax.
School can be stressful at times.
If my classroom did not have windows, I would design windows with changeable scenarios. I would also create student-teacher time. I want to make learning and teaching fun not only for the students but for myself as well. My classroom will never be dull. Most important there will be a minimum of 15 minutes set aside each day for reading and discussion.
