I have an education question for anyone with expertise in assessment:
Are there any studies examining the notion that marking all of one assignment/paper contemporaneously leads to more consistency?
It strikes me as intuitively true, but I’d love to find citations to studies that have examined this.
So far, I’m turning up empty.
Is it possible that NO-ONE has studied this claim to see if it actually has merit?
I’m not saying it isn’t true; I am asking how we can be sure it *IS* true?
For my part, I can say from 1st hand personal experience that I DO NOT grade the first exam in the exactly the same way as I grade the 20th, no matter how much I may try to.
Since I gave up using hard deadlines in my classes, I get assignments submitted to me throughout the term. Also, since fast turn-around of feedback is very important in my classes, I mark within a few days of those submissions. I have found that, at least, for me, I do the best job of marking on the FIRST assignment when I am doing a bunch at the same time. I don’t like that that’s true, but it is. When I get things handed in at various times, and when I mark them as they come in, I end up effectively marking EVERYONE’s assignment as if it were the first one.
Has anyone studied this?
