Why co-note?

It was a Tuesday evening. I had just finished marking a set of 22 essays — two hours of careful annotation, rubric rows filled in, margin notes written in full sentences, suggested fixes for various mistakes — the usual.

The next morning, I handed them back. Within thirty seconds, every student had flipped to the last page, looked at the grade, and put the essay away. Two students, the most studious ones, looked at the feedback and started mentally working on the changes they would make on the resubmission and had a few questions that I happily answered. The others just looked at me, waiting for the new lesson to start. One student asked me why he got that band, as if he didn’t hold in his hands the whole explanation in detail.

I stood at the front of the room and realised: everything I had written the night before was already in a mental bin. The feedback was just the fine print no one reads before agreeing to terms and conditions. It had simply never been “received” — and I had stayed up until 2 a.m. grading.

This isn’t a rare experience. Every writing teacher I’ve spoken to has the same story. I spend more time on comments than the student spent writing the essay. The student sees the grade and stops there; the grade is the validation.

The problem isn’t that students are lazy (they are, but it’s not the main issue here). It’s that the grade makes the comments optional. The moment the score is visible, there’s no reason to engage with anything else unless the grade is unexpected. The feedback loop closes — but not in the direction intended.

I started experimenting with a simple rule: no grade until the feedback is resolved.

Not read. Resolved. The student had to look at each tagged error, acknowledge it, and either revise the sentence or write a one-line response to show the work they’ll do on the issue. Only then did the score unlock. If we didn’t have much time, they could verbally tell me what they would change in each instance, and I could approve or deny on the spot. After all was settled, I would tell the student their grade and write it on the sheet in red ink.

The first time I tried it, the number of questions I got after class was overwhelming. Students who had never once asked about their feedback were coming to me with specific questions, “You flagged this as a coherence issue but I don’t understand why the paragraph doesn’t flow”, setences rarely heard under the old system.

I finally did it. I put the struggle where it belongs: the student. They are the ones with something to learn. Why was I doing the climbing? The best thing that happened with time is that I cut my grading time in half. Students became so familiar with the notes, rubric, and feedback style that my grading became looser — with the same results. I can now write “5 x SVA -10” and they will look up the mistakes by themselves, find each last one of them, and fix it without me flagging them one by one. I think it’s a game for them now.

That experience eventually became the thing that I built co-Note around. Not the rubrics, not the error tagging — though those help — but the gate. The idea that a grade is not released until some learning has actually happened.
