Most feedback is written, read once, and never used. Four short lessons on making feedback land — then a self-check you can run before your next marking pile.
Feedback that's only transmitted rarely changes anything. Treat it as a loop: students need a chance to respond, ask, and act.
Students can't change a grade that's already in. The most useful feedback is about the next piece of work, not just the last one.
Late feedback is dead feedback. The trick is to make it timely and personal without doubling your workload.
Even great feedback fails if students can't interpret or act on it. Feedback literacy is a skill you can teach.
