A corrected sentence can hide an unchanged mental model
A student learns to say that evaporation occurs below boiling temperature but still predicts that water cannot evaporate in a cool room. Conceptual change assessment checks whether the student’s explanatory model has genuinely shifted.
Identify the initial idea
Ask the learner to explain and predict before teaching, not merely choose an answer.
Teach the mechanism
Use appropriate observations, representations and reasoning to address the misconception.
Assess prediction and explanation
A correct label is weaker evidence than a justified prediction in a new context.
Use contrasting situations
Compare evaporation and boiling or other easily confused scientific processes.
Check delayed understanding
Revisit the concept after time has passed to identify re-emerging misconceptions.
Look for independent transfer
The learner should apply the idea without prompts or chapter labels.
Break-test: the student repeats the teacher’s words but predicts incorrectly
Does the assessment reveal the unresolved causal model?
