INTRODUCTION

English translation pending.

CORE DEFINITION

POE is an instructional strategy with three steps. Predict asks learners to state what they think will happen and to write down their reasoning before seeing any result. Observe has them watch or run the demonstration and record what actually occurred. Explain asks them to account for the difference between prediction and observation, which requires revising the mental model that produced the prediction. The strategy's premise is that a prediction made in advance commits the learner to a position, so a conflicting observation produces cognitive conflict that passive presentation does not.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use prediction with reasons: write the expected outcome and the reasoning behind it before seeing the result. - Use observation record: note what actually happened without editing it to match the prediction. - Use discrepancy explanation: explain why the prediction failed and what model would have produced the right one.

Anchor fast decisions

A correct answer delivered before any prediction is assimilated into whatever model the learner already holds, which is why misconceptions survive instruction. Committing to a prediction makes the learner's model explicit, and a contradicting observation creates a discrepancy that cannot be ignored. Explaining the discrepancy forces the learner to identify which assumption was wrong and to construct a model that accounts for the observation, which is the step where the misconception is replaced. Without the initial commitment, the conflict never arises.
