My interest in assessment & grading began shortly after the first few months of teaching right out of grad school. I noticed that some students did well with the content from the first few textbook chapters, but others didn’t do so well at all. Thus, beginning the year with low self-efficacy that was hard to turn around. By November, I realized that students were comfortable with the vocabulary and grammar from the first few chapters of the textbook. Then hit me; if I had just delayed those first assessments by a month or so, ALL STUDENTS would have aced them! What is more, the students who actually improved had that lower 1st quarter grade (e.g. C) averaged with the new, higher grade (e.g. A), producing a skewed reflection of their ability (e.g. B). None of this made sense; I was playing gods & goddesses with my students’ GPA.
I began researching how to arrive at a course grade that actually reflected ability—not just the averaging I was familiar with and somehow never questioned (or was even taught about in grad school). I spent months reading up on grading from experts like Marzano, O’Connor, and even some stuff from Alfie Kohn. I moved towards a system that showed where students were at the very moment of the grading term’s end without penalizing them for understanding the content slowly at first, or even having those bad days that students inevitably have. This was how I came to use Proficiency-Based Grading (PBG), and subsequently the kind of no-prep quizzes that haven’t added anything to my planning time in years.
If you’re ready for that, hooray! If not, at least consider 1) NOT averaging grades, as well as 2) delaying your assessments until students have already shown you that they understand the content!
