Learning Science · Feedback that leads to a next step
A criterion, the current work and the gap
Make feedback interpretable by connecting the goal, the current work and a specific difference between them.
Use the examples to connect this lesson with the earlier topics. No specialist equipment is needed.
Back to the chapterAfter reading, you can
- Describe a criterion in terms of observable work.
- Identify a gap without treating a score as a complete diagnosis.
Compared with what?
A comment says that a paragraph needs improvement. The learner needs to know what counts as an effective paragraph for this task and what the present paragraph does. A criterion is a feature used to judge the work. For an argument, it might concern whether the evidence supports the claim; for a calculation, it might concern valid operations and correct units.
The current work is the evidence to inspect. The gap is the difference between what that work shows and what the criterion requires. A score may summarise a judgment but usually leaves several possible gaps hidden. Two learners receiving the same score may need quite different next steps.
Make quality visible
Use a short description and contrasting examples to show what the criterion means. "Explain your reasoning" is vague until learners see a response that names an answer and another that connects it with evidence. Compare the difference in the work itself. A rubric can help, but its words need interpretation and examples.
Complex tasks often involve multiple criteria that interact. A paragraph can be clear yet scientifically inaccurate; adding more detail may reduce relevance. Avoid reducing quality to a count of visible features, such as requiring exactly three examples regardless of their function. Explain which feature matters to the present goal and why.
| Element | Concrete example |
|---|---|
| Criterion | Reader can identify variable and unit |
| Current work | Vertical axis says temperature only |
| Gap | Temperature unit is missing |
| Action | Check the measurement record and add the correct unit |
Choose a gap the learner can act on
Ask the learner to locate the relevant evidence in their work and restate the gap. This checks whether feedback is understood before revision begins. If they cannot recognise the criterion, teach it through a comparison. If they recognise it but cannot produce a better response, model a useful move or provide a focused practice task.
A formative-assessment theory emphasises learners understanding quality, comparing their work with it and having ways to make changes. This is a framework for designing learning, not proof that showing a rubric alone improves every outcome. The complete loop requires an interpretable standard, a meaningful comparison and an opportunity for informed action.
Worked example
A graph with an unexplained axis
What is the actionable gap in a graph labelled only “temperature”?
- The goal is to communicate measured temperature over time. The criterion requires a reader to identify each variable and its unit. The learner’s graph labels the vertical axis "temperature" but supplies no unit. The gap is specific: a reader cannot tell whether 20 means degrees Celsius or another scale.
- Feedback directs the learner to inspect the measurement record and add the correct unit, then check the horizontal axis too. It does not prescribe a prettier title as the main fix. The criterion, current evidence and revision are aligned with interpreting the data.
The missing temperature unit prevents interpretation. Check the actual measurement record and add its unit, then inspect the time axis.
Try it yourself
Think through each question before opening the answer.
Why is "7 out of 10" an incomplete diagnosis?
Show the answer and reasoning
It summarises performance but may not identify the missing concept, invalid step or communication issue.
Inspect the work against relevant criteria.
How can an example clarify a criterion?
Show the answer and reasoning
Comparing two responses makes the feature visible, such as the difference between naming evidence and explaining how it supports a claim.
A response containing an evidence label and one explaining its relevance show different work.
A learner recognises a gap but cannot fix it. What is missing?
Show the answer and reasoning
They may need a strategy, model or component skill for making the change.
Awareness alone does not provide the means of revision.
What to carry forward
- Feedback needs a meaningful reference point.
- Locate a specific gap and teach a way to address it.
