I have a year 12 Theatre Studies lesson I'm planning for later this week. I have the basic PowerPoint which I use as a base every year, but every year I have a different number of students in the class, with different abilities.
Last year I had 5 students, this year I have 9. Theatre Studies is practical as well as theoretical, and each student needs a tailored approach - if we look at a Shakespeare speech, they need to work on an equal section - or I need to annotate a second speech for more students.
I've also had to adapt the content - last year the students did Romeo and Juliet. This year they've already confirmed they want to do Henry V. It's a very different play - I have to re-work the whole approach
Plus several other issues which I won't go into.
It took me about 90 minutes to rework the lesson and I've also had to differentiate the home learning element of it. I also need to plan the delivery over Teams which is a lot different to class delivery.
Their homework will take me probably 20 minutes each to mark. That's 3 hours.
I also teach years 7-10 and have a form, which is pastoral and as it's year 12, we are working on UCAS applications. There are 20 students in my form. Their personal statements and tutor references are as individual as they are and I will spend hours with each of them on this. Hours
If I work with 4 students a week, that will be at least 4 hours a week extra for 5 weeks. At least.
Stuff takes a while.
