<p>Walking around can be energizing and stimulating. Students respond well.&nbsp; I like to walk around a lot in a classroom, especially when working on a class exercise. Sometimes it give me a chance to pause by a student's desk who is "weaker" in a study and I can offer a bit of insight and then move on. If gives me a good idea where my students are individually and as a group and what I may have to do to "reteach" or "add to" material I have presented.</p>
