Lenny,
To answer your question of why I mark less now than normally:
I mark as little as possible normally, mainly assessments sat in controlled conditions in a classroom. The rest of the time I normally go through prep in class. Firstly, and most importantly, social media has made marking prep in Sciences (and, I would guess, maths) fairly pointless. The pupils are all in chat groups and (positively) help each other and, far less positively, just nick each others’ answers. Secondly, I find it boring and am just not prepared to spend hours doing it for very (if any) limited gains in pupil progress and attainment. I make exceptions for the sixth form and Year 11.
I now also have my own (primary aged) children half the week, who do not have the benefit of any face time with their teachers, so I teach them too.
It is very important for teachers, IMO, to enjoy teaching and ‘have a life’. They can then bring this to the classroom.
There is a perception here, and many teachers even buy into it, that ticking every SLT box by working 14 hours a day makes one a brilliant teacher. It really doesn’t.
If you think back to your school days, the inspiring teachers were the ones who walked into the classroom saying ‘erm, where were we..’ and them delivered a totally fascinating lesson complete with diversions into totally unrelated areas, with energy and enthusiasm obviously present throughout.
