When students begin a difficult question, their first instinct is often to search for a formula, copy a familiar method, or wait for a hint. One strategy I have found useful is asking them to predict the answer before completing any calculations.
A prediction does not need to be exact. In math, a student might decide whether the answer should be positive or negative, large or small, or greater than a value already provided. In science, they might anticipate how changing one variable will affect another.
This simple habit encourages students to think about the meaning of a question before focusing on its mechanics. It also gives them a way to judge whether their final answer is reasonable. If a calculation produces a negative distance, an unexpectedly large probability, or a trend that contradicts their prediction, they are more likely to pause and check their working rather than accept the result immediately.
Predictions are also valuable when they turn out to be wrong. The difference between what a student expected and what actually occurred can reveal a misunderstanding that otherwise might remain hidden. Discussing why the prediction failed often creates a deeper learning opportunity than simply correcting the final answer.
Over time, this approach help students become less dependent on memorised procedures. They begin to recognise patterns, connect new questions with prior knowledge, and develop stronger academic judgement.
