I'm a qualified teacher.
I did a BA in education, and have QTS, so no post-grad.
Most if the course was spent in schools, on the job.
Bloody good job, IMO, since SEN theory was mentioned precisely once, for one afternoon session.
Behaviour management was a massive focus though. I did my training in inner London comprehensives, one of which had an 83% EAL rate, and 55% SEN. That was reasonably gruelling, but I can now confidently assure you that I could teach pretty much anywhere.
I saw qualified teachers in that school leaving the room in tears (men and women.) You would get such gems as "I'm going to fucking rape you, miss." These are kids who need strong, consistent boundaries from well-trained, consistent individuals.
I'm perfectly willing to accept that highly trained captains of industry might be able to impart information to a well- motivated top set who are interested in learning.
Dump them in a session with my year 9 group that contained variously
-a 6', 18 stone child who had a reading age of about 5, so acted out to hide it
- a boy with no English at all, recently arrived from a country where he had been a soldier
- a girl who lived separated from her parents in a refugee camp, in this country as an unaccompanied minor
- looked after, abused children
Plus the normal range of teenage shenanigans (who's shagging who, which wee girl is pregnant/ having a scare, who's using drugs etc)
How well would your average degree educated person on the street cope?
One class in one school, but pretty "normal" for inner city cohorts.
Teacher training is about a lot more than subject knowledge.
