Two similar explanations can lead to very different conclusions
A student says a puddle dries because the water boils in the sun. The correct explanation is evaporation, which can occur below the boiling point. Contrasting these ideas helps learners recognise the scientific feature that matters.
Identify the misconception precisely
Do not assume every wrong answer has the same cause. Ask the learner to explain the reasoning.
Choose a revealing comparison
Compare situations that look similar but differ in the defining mechanism.
Use evidence and representations
Particle diagrams, observations and simple experiments can clarify why one explanation fits.
Avoid teaching only a prohibition
Saying ‘never call it boiling’ is weaker than explaining the conditions for boiling and evaporation.
Invite students to predict
A prediction can reveal the learner’s underlying model before correction.
Check a new context
Ask about drying clothes or evaporation from an open container without naming the concept.
Break-test: the learner memorises the correct word but retains the wrong mechanism
Can the teacher diagnose and repair the explanation?
