Sometimes called the feedback cycle. Distinct from a review at the end of a project — feedback loops repeat across iterations.
A feedback loop is the structured cycle of work, review, and revision that converts time spent into skill. A learner ships a draft, receives concrete feedback against criteria, revises, ships again, and repeats. The shorter and more concrete the loop, the faster the skill grows.
The two ingredients that make a feedback loop actually work are concreteness and timeliness. Generic feedback ("this could be stronger") does not move the work; specific feedback ("the recommendation in section three contradicts the data in section two") does. Late feedback is weaker than fast feedback because the learner has moved on.
Every Ewance challenge runs an explicit feedback loop. Reviewers — sponsor, professor, or peer — apply the rubric to the student's deliverable and produce concrete written feedback against each criterion. The student revises, the loop runs again. The rubric makes the feedback specific; the platform makes it fast.
The fastest way to know whether challenge-based learning fits you is to ship one.
