The first year will be hard, but you'll have more power than you did on prac. Be consistent and referee-like. Kids don't handle teachers bending their perceptions of what the teacher's role is, unless it's "cool teacher" - which then leads to your aforementioned "being walked over". So just be businesslike, and do what the other guy said in relation to school discipline plan, etc. Be the teacher, not their mate, and don't try to redefine teaching as we know it...just be one...
You might need those buddy teachers on hand, but if you do it in a way that makes you look like you're simply following procedure and not palming the kids off because "you can't handle them", you'll be respected. Before that though, get on top of things yourself. Senior teachers get a little annoyed at newer teachers who kick their kids out too often...
And don't get hung up on finding your discipline strategy. There are many, and none of them work all of the time. It's between you and the kids, so just get knowledgeable about them. Takes ages. In the meantime, use the phone, and ring the parents often...
Thanks for the tips and advice. Will definitely take into consideration.
I guess I'm pretty lucky that I've gotten a job where my brother works, so he's filled me in about a few things already.
I've tried the 'cool teacher' with High School students and it worked a treat. Not so much with Primary students, they completely walked over me (which is partly my mentors fault because they did the same with her).
