A worked example is a complete, correct solution to a problem — a model answer to an essay question, a fully solved maths problem, or an annotated piece of student writing. Used actively, worked examples are one of the most efficient ways to close the gap between what you can currently do and what the exam requires.
Why are worked examples so valuable in revision?
Cognitive science research on the "worked example effect" — extensively reviewed by the Education Endowment Foundation — shows that novice learners benefit more from studying worked examples than from attempting problems independently when the content is new to them. This is because trying to solve a problem you do not yet understand is cognitively overwhelming; there is no efficient path to a solution, so you expend effort without learning. Studying a worked example, by contrast, lets you focus entirely on understanding the method.
As you become more skilled, the balance shifts — practice problems become increasingly valuable and worked examples become less essential. This is known as the "expertise reversal effect." Understanding this means you should use worked examples more at the start of a topic and practice problems more once you have the basics.
What kinds of worked examples are available to GCSE students?

| Mark scheme exemplars | Written responses with examiner commentary | Essays, extended answers |
| Textbook fully-worked solutions | Step-by-step maths and science problems | Calculation questions |
| Examiners' reports | Comments on what high-scoring responses do | Understanding mark allocation |
| BBC Bitesize worked examples | Topic-specific walkthroughs | Getting started in a new topic |
| Teacher-annotated model answers | Bespoke to your school's specification | Understanding local expectations |
How do I use a worked example actively, not passively?
Simply reading a worked example and thinking "yes, that makes sense" produces very little learning. The "sense of understanding" you get from following someone else's correct solution is much weaker than the understanding produced by attempting something yourself. Here is a step-by-step method:
- Read the question, then close the worked example. Before looking at the solution, spend one to two minutes attempting the question yourself, even if you do not know how. Write down what you do know. This primes your brain to notice where the worked example does something you did not.
- Study the worked example step by step. For each step, ask: "Why did they do this here? What rule or principle are they applying? Could I have known to do this?"
- Identify the moments of decision. Worked examples often look deceptively simple because each step follows logically. The difficult part is knowing which step to take first, and why. Focus on those decision points.
- Cover the example and attempt a similar problem. The transfer test: can you reproduce the method on a fresh problem without looking? If yes, you have learned something. If not, return to the worked example and identify which step you missed.
- Explain the method aloud. Talk through the worked example as if you are teaching it. Where you cannot explain a step clearly, you have not understood it yet.
A worked example of studying a worked example: GCSE chemistry
Suppose you are studying balancing equations and you find this worked example: "Balance the equation: H₂ + O₂ → H₂O"
Step 1 — Attempt first: You try and write "H₂ + O₂ → H₂O." Done?
Step 2 — Study the solution carefully:
- Worked example: Count atoms on each side. Left: 2H, 2O. Right: 2H, 1O. The oxygen is unbalanced.
- Adjustment: 2H₂ + O₂ → 2H₂O. Count again: Left: 4H, 2O. Right: 4H, 2O. Balanced.
- Decision point: Why adjust H₂ to 2H₂? Because changing O₂ alone doesn't fix it without affecting the ratio.
Step 3 — Attempt a similar problem: Balance CH₄ + O₂ → CO₂ + H₂O. Use the same decision-making process.
Step 4 — Check without the example. If you can balance it correctly without looking back, the method is beginning to transfer.
How do I use worked examples for essay subjects?
For subjects like history, English, or geography, the worked example is a model essay or extended response. The same principle applies — active engagement matters more than passive reading.
- Read the essay question, write a plan, then compare it to the model answer's plan
- Identify one or two techniques in the model answer that you would not have used — specific phrases, structural moves, evidence choices
- Write one paragraph of your own response before looking at the model paragraph, then compare
Frequently asked questions
Should I copy out worked examples as part of revision?
Copying a worked example without thinking is a passive activity with limited revision value. It is more useful to attempt your own version first and then compare. If writing it out helps you think about each step — rather than just transcribing — then it has value. The test is whether you could reproduce the method on a fresh problem after the exercise.
How do I find good worked examples for my subjects?
Mark schemes and examiners' reports are the most authoritative source — they are produced by exam boards and tell you exactly what the marking criteria reward. BBC Bitesize provides good worked examples for most GCSE subjects. Your teacher is often the best source for subject-specific model answers aligned to your specification.
How many worked examples do I need to study for a topic?
Usually two or three per question type is enough to extract the pattern. Beyond that, practice problems are more valuable than more examples. The worked example phase is preparation for independent practice — it is not a substitute for it.
Can worked examples make me too dependent on seeing the method first?
This is a legitimate concern, and it is why the step "attempt before looking" is important. If you always study the worked example without trying first, you may develop the feeling of understanding without the ability to transfer. Exam conditions do not provide worked examples — only your memory of having studied and practised does.
