I do wish we could instill such a respect in the classroom. Other writers have written about the interruptions of a class period - door knockers, intercoms, and people entering and exiting freely as if nothing of value was happening inside. The last two weeks were especially bad:
Can we possibly schedule things better and respect the lessons that are being taught? The time that it takes to readjust attention spans and maintain continuity is just not worth the interruption. People on the outside do not see what an interruption - even the simplest interruption - can do to a lesson. When my students are rolling with me, enthralled in the most suspenseful or intriguing portion of an experiment or a story, I need for them to stay with me. I don't need them taking little breaks from the lesson.
