OP, what does an A mean? 20 what? What are the points for?
These are generally arbitrary measures which mean nothing. I know loads of random red pen makes parents feel better, but (yeah, hit me, I'm gonna go for it) it has been proven over and over again to have bugger all impact on students' learning.
I've just spent five hours marking a set of exam papers for one and a half classes. I am resentful, because this means that my lessons tomorrow are going to be pretty ropey because I just don't have time to plan them properly.
How many of those students will actually look at any of my comments? How many of them will use the information that I have spent hours writing to help them raise their grade? Maybe three might remember it vaguely. The rest of them will spend the whole lesson shouting across the room at each other trying to find out what marks their friends got.
Right. Think to yourself. Why do you want a random grade or number? What do you think it is:
a) A measure of the teacher's opinion? What if the teacher liked or disliked your child more than other students? Would this be a reason for giving them a higher/ lower score?
b) A measure of the ranking of your child within the class? Why would you want this? What on earth does it mean? You are creating some sort of artificial norm against which you are measuring success and this whole concept hinges on you wanting to be able to tangibly see your child doing better than somebody else's
c) A set of criteria. And what are these criteria? How on earth, in a subject like Art can you measure how well a child is doing? Really?
The very best sort of assessment is actually self-assessment, as you are supposed to be preparing students for their future lives in which it will be them who are responsible for assessing the quality of their own work. Thus helping them to learn how to evaluate it is the best form of learning, giving them confidence in their own achievements and certainty about the best way to improve it.
The piece of research most worth reading is called, 'Inside the Black Box' by Paul Black. It would make anybody question the purpose of assessment. Some very important points that he makes include:
- Why do we assess at the end of a course? If the purpose of assessment is to help students learn, how can they learn how to do better from something that is done after they have finished?
- If a test was valid proof of a students' result or ability, surely they would get the same result if they did it again? If you can alter your result, what are they actually a test of?
Sorry OP. You caught me at a bad moment. Since I read the research above (and other stuff too) and saw evidence for what I'd always known, marking puts me in a very bad mood.
BTW I didn't ask, but if you're child's in KS3 they won't be getting much marking done in exam season.
