One Third Makes It Worse

Over a third of feedback interventions decrease performance. Before giving feedback, check: does this comment address the work or the student? If it is about the student, rewrite it.

Why you might use it

The problem it may help with

Kluger and DeNisi's finding is one of the most sobering in this strand: over a third of feedback interventions made performance worse. Feedback is powerful, but the power runs in both directions.

The dividing line in their analysis is where attention goes. Comments that keep a pupil's attention on the work tend to help; comments that pull attention to the self tend not to. The check on the card, work or student, is the practical version of that finding.

What it might look like

One version of it, in a classroom

Before returning books, a languages teacher reads her own comments as if she were the pupil receiving them. Two turn out to be about the pupil rather than the translation in front of them; both get rewritten to name something in the work: this tense is the one to fix, these five words need the accent check you used above.

What to notice

Reading what happens

  • How pupils respond in the moment work is returned: heads down into the work, or looking around comparing themselves with others.
  • Which of your comments you would be glad to receive about your own work.

Things to think about

Before and while you use it

  • A comment can be about the student without naming them. Try harder, more effort needed and you can do better are all self-directed, whatever the phrasing.

The wider thinking

Where the evidence sits

As the strand's opening argument puts it, some feedback helps, some does very little, and some makes things worse; Kluger and DeNisi supplied the numbers behind that sentence. The card’s attribution stands as published: Kluger & DeNisi.
