I wonder if any other music teachers have come across this and how you dealt with it? I teach music in an independent school 3 afternoons a week to K - 3's. I teach in the auditorium, which is used for other things, like storing chairs, music stands, tables, etc. and the stage has a back door access and is used for storage when not in use. I am in my 3rd year there now and most of the teachers have been there forever, so I'm still "new" in comparison. The problem is that people just walk into the class (teachers, EA's included) without excusing themselves, distract my class which I work hard to keep engaged and sometimes proceed to make a whole bunch of noise which totally disrupts the flow of the class causing me endless frustration. It's not always the same person/people, and I'm wondering how I deal with this without seeming like I'm trying to 'throw my weight around'! I get the feeling that people think - "It's only the music class" and I want to try and change that mind set, but in an effective way that will result in a mutual respect not resentment. I've thought about putting some kind of sign on the door when I'm using the room as a start - anyone have any thoughts about this?
