Interesting thread but I don't really think I'd feel like I was 'admitting' to anything - I do what I feel (as a professional) is appropriate in my classroom, with my students within the framework of the school, to maximise the learning that goes on/progress made.
- listen to music players whilst completing work (unless it's a music lesson/relevant) - no, but I do have an SN class in which I will put the radio on through my laptop if we are doing revision/past papers as it helps them to focus and helps to prevent behaviours like work refusal, wandering around etc
- eat and/or drink (not water obviously) - no, but I do turn a blind eye to a few children eating in registration time as I know full well they have had no breakfast (if they have breakfast = less likely to behave poorly in lesson 1)
- get up and walk around at will - how exactly do you propose that I (a 5ft4 female) prevent a 6ft Yr 11 student from wandering? That is not to say that I do not address it, but it does happen.
- swear/use foul language to you/each other under their breath (whilst you pretend not to hear) - if I hear it, I address it, swearing at me = they go home.
- dry-hump each other (to which you merely raise an eyebrow) - I've never actually had this happen but similar attention-seeking behaviours are sometimes best ignored (you don't want to draw other pupils' attention to them as then they will start to perform for the class)
- routinely turn up to lessons with no pens, pencils, books - not a battle I'm willing to fight tbh, if they don't have a pencil or whatever, I give them one (this is in line with school policy)
- treat the floor as a bin - no
- deface books - they deface it, they recover or copy out or similar in their lunch hour
- break pens etc - again, I'm not quite sure how I'm supposed to actively prevent a child breaking a pen but I would address it
- use their mobiles for texting (against whilst you pretend not to notice) - not really a problem at my school (thank the lord - every sympathy for those of you where it is)
Why are you asking?
