I am a teacher. I understand you may not wish to say how you know these things, I'll try to explain possible reasons. I'm not saying I'd do these things - but the beauty of teaching is that we all have our own styles.
Shouting is often subjective. Now and again a child will tell their parents I shouted when I didn't think I had.
Breaks: Peer pressure is often used to try to get the others to behave. I suspect the idea behind it is to get the other children to behave because they're all losing out. It's a behaviour strategy, I'm not saying it's necessarily a good one. A lot depends on the children themselves whether you should use it.
Names on the board: Again, a recognised behaviour strategy. Can work brilliantly, the child does not want to be on the board. Can be counter-productive, the child may like the attention.
The tally thing: I understand you don't want to go into detail. It can be used as a peer pressure/intervention style strategy. Obviously depending on the transgression.
I suspect that Year 1 is a little young for these strategies. And I will admit that none of them are ones I am a particular fan of. But they are recognised strategies that are out there in education.
I guess to decide if you are BU or not you have to ask yourself: do these strategies actually work for this particular class? If so, then they're probably ok.
