Given that we're talking about workload, I thought I'd try and demystify the process of lesson planning. I probably won't succeed.
I think a large number of people (not in this thread, but generally in life) vastly underestimate the amount of planning required in state schools. For each one hour lesson I taught, on average, I would spend around an hour planning. Sometimes it was easier and took a little less time (I had two year seven classes, for instance, so there was a certain amount of duplication*), a lot of the time it was much harder, and took much, much longer (I did not have proper schemes of work for some of my classes, so had to start entirely from scratch, resulting in weekends, not hours, of work), but 1h prep for a 1h lesson is a fair average.
For some idea as to what planning involved,
here is a PDF of a lesson plan from one of my own Y7 lessons (names/details censored, of course). Looking over it, it's actually not a particularly good one - the learning outcomes are a bit basic, key answers are sketchy, and my assessment methods are poor. Eh, it's from near the start of my teaching career, and it's the first one I laid my hands on and could quickly anonymise.
Still, one of these, for each and every lesson. That's around 18-19
every week when you're newly qualified, and 22ish after your first year. Of course it gets easier the longer you teach, and the plans can become less detailed. You can also recycle plans to a small extent, but as I note below, every class is different, so every class needs an individual plan.
This was in addition to an overall weekly plan, to make sure I was sticking to schedule, was not too far ahead of/behind other teachers, to make sure I would cover the specification, and to ensure my daily workload was managable (a hard feat, ensuring you don't accidentally plan a day with five heavily practical lessons, for instance). This is what was done in the infamous 'teacher's planner'.
Those plans were also in addition to my weekly requisitions - as a Science teacher, I needed to take my weekly lesson plan, work out what equipment I needed for each lesson, and then fill out a requisition form a week in advance, for the following week, to allow the technicians to prepare equipment for my lessons.
I also had to prepare any exercises, worksheets, homeworks etc. for students to do during/after lessons. They're not all pre-prepared - many you have to write from scratch. That's surprisingly difficult.
That just covers the lesson planning. I then of course had to...
- Deliver the lessons - that of course was the majority of my '8am - 3:30pm work'
- Evaluate some lessons, to ensure that I was doing the right thing
- Mark classwork, homework, tests, exams, coursework (very, VERY big job), and any other work.
- Moderate work marked by other teachers, and evaluate my marked work that's been moderated
- Track each students progress, making regular judgements as to their attainment, progress, understanding etc. (Remember, in a Secondary teacher's case, that could be 200+ students. In a Primary teacher's case, that's 31-odd students in 8+ subjects)
- Write full summative reports to go to parents. Tricky, especially with so many students
- Help students falling below target, or who are keen to learn more, outside of planned lessons
- Deal with behavioural and work related issues - detentions, logging problems, spotting patterns etc.
That's just curricular stuff that I can remember off-bat - there is undoubtedly more that I have omitted.
That doesn't include pastoral work - looking after a tutor group, and ensuring the social welfare of all those pupils. Preparing for tutor time as well.
That doesn't include any extra-curricula activities, which as a teacher you are expected to (and want to!) be involved in.
Overall, it's a huge amount of work
I'm not trying to suggest that other professions don't have large workloads - they of course do. Just never, ever suggest that teaching is a 'doss subject', to use a pertinent bit of school language.
It's anything but.
*Note that I'd still have to produce a full lesson plan for each and every lesson, even if it was the same lesson to two Y7 classes - two classes, two different sets of pupils, two abilities, two differing styles that worked with one but not the other etc. etc. etc.
