If students are telling you they ‘don’t know anything’ and it’s just before the exam, something has gone wrong. There’s only one thing for it, cramming.
But if students are saying this, might it be a good idea to consider why it is that they’ve sat in your classroom for 2 years and remember nothing?
Just think, current year 10 is next year’s year 11. Current year 7 is year 11 in four years.
Forget progress in 20 minutes, we can all play that game.
How about some long term learning?
What are you doing as a teacher, leader, manager to ensure that children are really learning?
Maybe it’s time to change what you’ve always done and do something that ensures last minute cramming isn’t needed.
