Feedback and its effectiveness in a computer-aided personalized system of instruction course.

Researchers built a computer course that teaches college material using the Personalized System of Instruction.

Students first studied alone, then took short quizzes on the computer.

After each quiz, a classmate gave written feedback through the same computer system.

The team tracked how accurate the peer feedback was and how often students actually used it.

Peer comments hit the mark a large share of the time.

Students followed the advice a large share of the time.

Those numbers show peer feedback can work in a computer-managed course.

It is not perfect, but it is good enough to keep.

Moss et al. (2009) looked at 55 staff-training studies and found the same pattern: feedback raises accuracy.

Their meta-analysis says the best recipe is classroom teaching plus on-the-job coaching with verbal feedback.

McIntyre et al. (2002) now shows the same boost can come from peers inside a computer course.

Cochrane et al. (2022) trained peers to give video feedback on weight-lifting form.

Every lifter reached perfect form, proving peers can give useful feedback even outside the classroom.

Blackman et al. (2022) warns that watching alone is not enough.

Most trainees needed direct feedback to hit the goal.

McIntyre et al. (2002) agrees: adding peer comments lifted performance above self-study alone.

If you run a computer-based course, add a simple peer-feedback step.

Let students type short notes after each quiz.

Expect about six in ten to use the advice and scores to rise.

It costs nothing but a few minutes and may save you hours of later re-teaching.
