I shouted at a year 9 boy in my very first lesson with him. I can read students well and it was obvious that if I had not put him in his place quickly he would think he was boss. It was short, very effective and we have got on marvellously since with a very 'positive relationship'. I did not scar him for life.
I was right about him. He is rather full of himself. Lots of student either fear or dislike him and he is very domineering in some lessons.
Teaching is to an extent about power. We are the adults. We aren't 'first among equals'. They do need to learn that the relationship is not meant to be a tussle and that they don't always have right to reply. I don't aim to intimidate or bully and we have all seen teachers who are bullies - but I do need to assert my authority over young people who don't always understand or accept the authority of adults. They also do need to be taught manners, and sometimes need to (even at age 15) be told what things are considered rude and insolent. It seems to me that they increasingly are not taught this by primary school teachers, other secondary teachers or by their parents.
Examples (provided by DS2) of knowingly rude behaviour : loud sneezing, loud 'bless yous' , going 'iIm sooooorrry', saying 'Oh my Goood' when told off. 'yawning loudly. , loud apparently uncontrollable hiccups This has definitely become more commonplace. And all, if not accepted as rude by the child would definitely, after a while, incur my wrath. Either a sending out (actually I was always told that was weak), a stern talking to inside or outside of the room, a withering look , a lecture or - if all of those failed , or if the child themselves shouted (they do you know) I would and will shout. If they apologise, learn, move on ,and if the teacher also puts it away and forgets about it afterwards and juts carries on then no damage has been done. Some non shouting teachers are actually very fussy, quite vengeful and full of processes and administrative procedure And are often the 'telling someone else in the hope that they will deal with it' types.
I am not going to go into the exact details of why I shouted at the student the other day but, suffice to say, many other strategies had been deployed first (although I can also do the 0-60 in 2 seconds and back again approach).
I would add that I have increasingly perceived that students think of most female teachers as soft targets these days and , particularly when they are unknowns in a corridor, the default is to be rude and difficult when reprimanded. Definitely in those circumstances I do relish showing them who is actually boss.
