This will be a bit of a rant, but I'm starting to feel like I'm all for a detention for forgetting equipment. I'm a secondary school teacher (on my day off) and yesterday in one Year 8 lesson there were 5 students who arrived without pens (after lunch, so not the first lesson of the day), 3 who wanted to borrow a ruler to underline the date and title, 2 who asked to borrow a pencil. Each of these asked me at separate points. Two of the pen students had just sat there and not even bothered to ask for ten minutes until I noticed they hadn't done the title, date and first task at which point they said "I don't have a pen" - one of them in a tone that heavily implied this was my fault.
Each time it roughly took me around 30 seconds to pause what I was doing, locate a spare piece of equipment (we lend out so bloody much and I share a classroom so things aren't always where I would leave them!) and give it to the student. So that was around 5 minutes of a 60 minute lesson just dealing with equipment issues.
Later on we self marked in green, and I got the pot of green pens out and then we spent two minutes all getting those handed out too. Students are meant to have their own, but I gave up that battle a very long time ago.
It drives me absolutely mad because something to write with is ESSENTIAL, and yet so many students just don't bring one. Or they do, but leave it somewhere. And we obviously have to give them one to write with, because otherwise they can't do anything! The rulers and pencil I suppose could have said no to the borrowing requests - but I do want them to do their work neatly, and until there's a big push on equipment and organisation again at my school, it's like swimming against the tide. We loose loads of equipment each week as students don't give it back. I can write down names as they borrow it, but that takes even more time...
Basically much as I would really dislike enforcing it, I feel that the super punitive 'detention for one missing piece of equipment' would probably improve things hugely as I strongly suspect most learners would organise themselves far more effectively than they are doing currently in my school!!
(Should add that I never begrudge lending a pen to a child who is clearly having an off day and has forgotten something for the first time ever, and always give students with SEND the benefit of the doubt...)
