Really struggling with classroom management

Spend half hour coming up with class rules that can be put up on the wall and consequences. I used to have my desks in an L shape (2together), you can move around them easily, students can do group work easily but all face the board. I found a U shape used to create more situations of throwing things across the room and shouting to each other

How long have you been teaching, does your school or college have a clear discipline policy that you are following? have you got a mentor, or someone who will give you practical suggestions?

Are your lessons planned, interesting, appropriately pitched and are you confident delivering them? Are they all disruptive or just a few and the rest are following on. Are you clear and consistent, do they know where they are with you and the activities?
Has this been going on since September?

You do realise that you are failing to provide them with an education if you can't get them on task, focused and learning? That there will be students in the class who are failing because of the disruption you are allowing that they are not a part of, and those that are disruptive are failing because you haven't got a clue that discipline doesn't involve barking orders that the class will ignore?
Are your children very young? Because yelling at teenagers is one of the least effective methods of getting them to listen and co-operate.
And WTF has attachment parenting got to do with inspiring, motivating and teaching 16 year old boys?
If you just can't do it, if all the boks on behaviour and classrom management aren't enough, and observation of other experienced staff isn't working, if they are learning nothing in your lessons, then there's only one thing you can do that is ethical and that's hand them over to someone else.

Do you want to tell us what the main issues are? I've been teaching teenagers for years and still get classes that I find a huge challenge - and the worst thing to hear is other people say 'oh, they're fine for me'

How is your classroom set up? Groups of desks is great with a well behaved class but with one like this a horseshoe works best.

Sit the students who cause the most problems at the ends of the horseshoe - if one acts up stand in front of him, with your back to him so that you can address the others but block him with your body (effectively cold shouldering) him

Once he has stopped move back to 'let him back in' to the group.

You don't need to bark orders, just be firm, fair and kind. Make the lessons busy and interesting and get to know the students and they will soon warm to you.

There arent two extremes of teaching style.

Sorry, rewrote that too many times and then didn't proof read!

Ask to observe them being taught by someone else. You don't need to 'bark' at them- there isn't two extremes of teaching style with nothing in between.

And parenting is NOTHING like teaching, so that has nothing to do with it.

Also I would look at your lesson content- give them interesting and challenging things to do that are worth behaving for.
