Thirty boards go up. Almost every pupil has written an answer. You scan the room, see plenty of correct responses and move on.
It feels like an effective check for understanding. But what have you actually learned?
Some pupils may have copied. Others might have guessed correctly. A pupil with the wrong answer may understand the concept but have made a calculation error.
Mini-whiteboards are brilliant for making pupils’ thinking visible, but participation isn’t the same as understanding.
Their value lies in asking the right questions, establishing a reliable routine and, most importantly, doing something with the answers.
The technique: a seven-step routine
The more predictable the routine, the more attention pupils can give to the question itself. Here’s a model you can teach, practise and use consistently.
1. Ask
Pose a focused question that checks something specific.
For example, after teaching collision theory, asking whether increasing temperature increases reaction rate will probably produce thirty correct answers. But it won’t necessarily tell you whether pupils understand why.
A more revealing question would be:
Why does increasing temperature increase the rate of a chemical reaction? Explain your answer using collision theory.
Think about the answers you’re likely to receive. What would a correct response demonstrate? Which misconceptions might the question expose?
2. Think
Give pupils independent thinking time before they write.
A quick recall question might need only a few seconds. A calculation or explanation will require longer.
Avoid letting the fastest pupil set the pace. The aim is to hear from everyone, including those who need more time to process the question.
3. Write
Every pupil writes an answer.
Keep responses short enough to assess across the room. If you’ve asked thirty pupils to write full paragraphs, you probably won’t be able to read them accurately when the boards go up.
For more complex explanations, break the question into smaller steps before asking pupils to bring their ideas together.
4. Hover
Once pupils have written their answers, give the instruction:
Hover.
Pupils hold their boards against their chests, with their answers facing inwards.
This prevents early answers from being displayed and reduces opportunities for copying. It also means everyone is ready to reveal their response together.
5. Show
Use a consistent countdown.
Three, two, one, show.
Everyone raises their board simultaneously and holds it still.
It’s a simple routine, but one worth explicitly teaching and rehearsing. If boards go up at different times, pupils may change their answers after looking around the room.
6. Scan and probe
Look across the room for patterns.
Is there a common misconception? Are pupils making different errors? Does a correct answer conceal incomplete reasoning?
Then probe the responses.
For the collision theory question, you might ask:
Why does a higher temperature increase the proportion of successful collisions?
Or show an incorrect explanation and ask pupils to identify and improve it.
The initial response tells you something. The follow-up question helps you find out more.
7. Respond
This is the step that makes the assessment useful.
If several pupils share a misconception, reteach the concept. If pupils know the answer but struggle to explain it, model a stronger response. If most appear secure, increase the challenge or check whether they can apply their knowledge in a different context.
And if you’re still unsure, ask another question.
Don’t collect thirty answers only to continue with the lesson you had already planned. Use them to decide what happens next.
Where teachers go wrong
Even with an established routine, mini-whiteboards can create a misleading impression of understanding.
1. Questions that don’t reveal enough
You ask a question that pupils can answer by repeating what you’ve just said. Every board is correct, so you assume everyone understands.
The fix: decide what you want to assess before writing the question. If you’re checking recall, a straightforward question is fine. If you’re checking understanding, ask pupils to explain, apply or distinguish between ideas.
A correct answer to an easy question isn’t a problem. Drawing too much confidence from it is.
2. Copying mistaken for understanding
One pupil raises their board early. Others look across and change their answers. Suddenly, most of the class appears to be correct.
The fix: protect independent thinking time, use “hover” and insist on a simultaneous reveal.
You want to see what individual pupils can produce, not how quickly they can copy their neighbour.
3. Moving on without acting on responses
The boards go up. You spot several incorrect answers, give the correct answer yourself and continue.
You’ve identified a problem, but you haven’t necessarily addressed it.
The fix: use the responses to choose your next teaching move. Probe an error, remodel a step, ask pupils to improve an explanation or pose a follow-up question.
The point isn’t simply to discover who got it right. It’s to work out what the class needs next.
What does the research tell us?
Black and Wiliam (1998) emphasised the importance of using evidence about pupils’ learning to adapt teaching. Mini-whiteboards offer one way of gathering that evidence, but their effectiveness depends on the questions we ask and how we respond.
We should be careful, though, about the figures that often accompany formative assessment in CPD sessions. Kingston and Nash’s (2011) meta-analysis reported positive but considerably more modest effects than some of the larger numbers in circulation, and Briggs and colleagues (2012) subsequently challenged aspects of that methodology. These studies also examined formative assessment in general. None of them establishes an effect size for mini-whiteboards.
There’s also an important distinction between what pupils can do immediately and what they’ve actually learned.
Soderstrom and Bjork (2015) distinguish between performance during practice and more durable learning. A correct answer immediately after an explanation doesn’t guarantee that a pupil will remember or apply that knowledge next week.
Mini-whiteboards give us a useful snapshot of current performance. To check whether learning lasts, we also need to revisit knowledge over time and in different contexts.
Try it in your next lesson
Choose one point in tomorrow’s lesson where a misconception is likely to emerge.
Plan a question that will expose it. Decide what different answers might tell you and what you’ll do in response.
Then practise the routine:
Ask → Think → Write → Hover → Show → Scan and probe → Respond
Afterwards, ask yourself whether the question revealed what you wanted to know and whether the responses influenced your teaching.
Thirty boards in the air might look impressive. But the real value isn’t in getting everyone to show an answer.
It’s in what those answers reveal and what you do next.
