Use learning errors to choose the next step
A learning error is a starting point for investigating a learner’s reasoning. Ask how the response was produced before deciding whether to clarify the task, model a method or revisit a concept.

Describe the response without labelling the learner
Record what you can see: the learner added denominators, omitted a unit or used an unsupported claim. Avoid labels such as careless, slow or weak. These labels do not identify an instructional response.
The same incorrect answer can arise in different ways. A learner may misunderstand the concept, misread a word or apply a familiar procedure in an unsuitable situation. One response alone does not identify the cause.
Ask for the reasoning
Try a neutral prompt: “Show me how you decided” or “What does this part represent?” Give the learner space to explain without announcing the error immediately. A drawing or concrete model may reveal reasoning that a written procedure conceals.
Use a second example to check your interpretation. If a learner treats one half plus one half as two quarters, ask them to represent each half using the same whole. Observe the explanation before deciding which relationship needs teaching.
Choose a targeted teaching move
If the problem is the instruction, clarify it and let the learner try again. If a step is missing, model that step and offer guided practice. If a concept is insecure, compare examples and non-examples with a suitable representation.
Do not simply increase the number of questions using the same method. Repetition can rehearse an incorrect approach when its meaning has not been examined. Make the important difference visible, then reduce support gradually.
Return to an independent check
After support, offer a fresh example that checks the same idea. Ask for a reason as well as an answer. If the learner succeeds only when copying the teacher’s representation, more guided work may still be useful.
Discuss common errors anonymously and with respect. Never display a child’s mistake to invite ridicule. A classroom can examine an incorrect example as an idea to investigate while protecting the dignity of the person who produced it.
Make it your own
Your planning task
Choose one frequent error. Write two possible explanations for it, a question that distinguishes them and a different teaching response for each explanation.
Check your plan
- The error is described precisely.
- More than one explanation is considered.
- The learner’s reasoning is checked.
- A fresh task checks learning after support.
