Does your school use google classrooms or anything like that because I do the following:
KS3:
Set as many homeworks as multiple choice recall/reinforcement quizzes as possible - that get marked automatically and the software collates the class responses for you.
Only set one big 'marking job' per class per half term. Hand out paperclips and get pupils to place paperclip where the work is - this means you can go straight to where the work is rather than spending any time flicking through pages to find it. That saves you a lot of time over an academic year.
Use a technique where sporadically you are getting students to mark their own class work/partners work using a success criteria set by you during the lesson - obviously works best with concrete answers.
KS4:
I use a whole class proforma as most of the time there there are general things that benefit everyone. It also has a copy of the exam board mark scheme attached. So I fill it in once, by typing it all up - I then print it off, photocopy it and then handwrite in the specific feedback for pupils.
On my proforma that I fill in there are the following titles:
Clarifying misconceptions:
Reflection questions for students:
Specific feedback: - I handwrite this in
Response from student/Ways to improve: - Which they fill in
On the mark scheme from the exam board and using a high lighter pen - highlight for the individual student where they are exactly.
KS5:
They have to email their work to me as I much prefer marking it on my computer than random pieces of paper.
Marking is a bane but hopefully some of these tips might help. 😀
