Teachers ask a remarkable number of questions — in many lessons, dozens in an hour. Yet a large share of them do very little. The teacher asks, the same quick learner answers almost immediately, the teacher says good and moves on. The room has the appearance of interaction, but most people were never required to think.
Questioning becomes useful when three things change: how long you wait, who is expected to answer, and what you do with the answer once you have it. None of these needs new materials. They are habits, and like most habits they feel awkward for about two weeks.
The two-second problem
Classroom research going back decades has found that teachers commonly wait around a second, sometimes less, between asking a question and either taking an answer or rephrasing it. In that time, only learners who already know the answer, or who are confident enough to guess aloud, can respond. Everyone else learns that if they wait, someone will do the thinking.
Extending the pause to three to five seconds, and pausing again after an answer before responding, tends to change who participates and how full the answers are. In practice, five seconds of silence feels very long at the front of a room. Count it silently. It helps to tell the group openly what you are doing:
I am going to ask a question and give everyone ten seconds to think before anyone speaks.
Announcing the pause turns silence from awkward into expected.
Changing who answers
No hands up
If learners raise hands, you hear from volunteers. A no-hands routine means you choose who answers, after the thinking time, so everyone has to prepare an answer. Some teachers draw names from a cup or use a randomiser; others choose deliberately to check particular learners. Either way, the rule is announced in advance and applied to everyone, so nobody feels singled out.
The common objection is that this puts shy learners on the spot. Two adjustments help a great deal: give thinking time first, and make it acceptable to say I am not sure yet, but I think it might be… A partial answer is a contribution, not a failure.
Think, pair, share
Ask the question, give individual thinking time, then a minute or two to compare with a neighbour, then take answers. Learners speak to the whole group having already said the answer once to one person. Quality rises, and you can listen in during the pairs to choose which answers to bring out.
Everyone answers at once
Mini whiteboards, cards with A/B/C/D, fingers held up for options, or a quick poll in an online class all let you see the whole room’s answer in a few seconds. This is the fastest way to find out whether to move on or reteach. If a third of the room holds up the wrong card, your next five minutes are decided.
Asking better questions in the first place
Not every question deserves wait time. What page are we on? needs none. The questions worth slowing down for ask learners to do something with an idea:
| Weaker question | Stronger version |
|---|---|
| Does everyone understand? | In your own words, why does the second step come before the third? |
| What is the definition of X? | Here are two examples. Which one is X, and how can you tell? |
| Any questions? | What part of this would you find hardest to explain to someone else? |
| Is this right? | A learner last year wrote this. What did they get right, and where did it go wrong? |
Does everyone understand? deserves special mention because it almost always gets silence or nods, and neither tells you anything. Replace it with a question that makes understanding visible.
What to do with the answer
The response to an answer is where most of the teaching happens. Instead of evaluating immediately with good or not quite, try one of these:
- Ask for the reason. What makes you say that? Even correct answers are often reached by a shaky route.
- Pass it on. Mai, do you agree with Duc? Why? This keeps everyone listening because they may be next.
- Ask for extension. Would that still work if the number were negative?
- Bounce to the group. Hands up if you had something different. Different answers are more useful to discuss than one right one.
- Hold back judgement. Collect three answers before saying which is strongest. Once you say correct, thinking stops.
Handling wrong answers
How you handle an incorrect answer decides whether anyone will risk one next time. A few principles:
- Find the reasonable part. Most wrong answers are a sensible idea applied in the wrong place. Say what it got right before what it missed.
- Treat it as useful material. That is a really common answer, and it is worth looking at why. The error becomes something the whole room learns from.
- Return to the learner. After the discussion, go back: Now that we have looked at it, what would you change? They finish the exchange having got it right.
- Do not rescue too quickly. A prompt such as look at the second line again is better than giving the answer.
Adapting for adults and online groups
Adult learners in workshops can find cold calling patronising if it is sprung on them. Explaining the purpose — I want to hear from everyone, not just the quickest — and using pairs first usually removes the problem. In online sessions, wait time is harder because silence can look like a broken connection. Say how long you will wait, use the chat for everyone to type an answer at once, and ask them to press send at the same moment so early answers do not anchor the rest.
Questions that check the whole lesson
Most questioning happens in the middle of a lesson, but two points matter more than the rest. At the start, a short question on the previous lesson tells you what stuck, and it gives learners a reason to recall it rather than wait to be reminded. At the end, a final question answered individually — on a slip of paper, in the chat, or aloud from three chosen learners — tells you whether today’s main point landed.
Keep a note of the answers. If the opening question on Thursday shows that most of the group lost Tuesday’s key idea, that is information about your teaching sequence, not about the learners. Two or three of these notes in a row are worth more than any end-of-term evaluation form, because you can still act on them.
Hinge questions
A hinge question is a single, carefully built multiple-choice question placed at the point where the lesson turns from one idea to the next. Each wrong option corresponds to a specific misunderstanding. If learners choose option B, you know exactly what they believe and what to reteach. Writing a good one takes ten minutes; it saves you from building the rest of the lesson on sand.
For example, after teaching that a plant needs light to make food, a hinge question might offer four explanations of why a plant in a dark cupboard turns pale, each wrong option matching a belief learners commonly hold — that plants feed from the soil, that water alone is enough, and so on.
A two-week practice plan
- Week one: pick two lessons and use announced wait time for every important question. Notice who answers who did not before.
- Week two: add one whole-class response per lesson, and replace every does everyone understand? with a question that shows understanding.
Ask a colleague to sit in once and simply tally how many different people answer. That one number is usually enough to show whether the habits are taking hold.
Frequently asked questions
How long should I wait after asking a question?
Three to five seconds for most questions, and longer for questions that need real thought. Announcing the pause makes the silence feel normal.
Is cold calling unfair to shy learners?
It can feel that way if sprung without warning. Thinking time first, pair discussion, and accepting partial answers make it far more comfortable.
What should replace “Does everyone understand?”
A question that makes understanding visible, such as asking learners to explain a step in their own words or choose between two examples.
Should I say “good” after a correct answer?
Not immediately every time. Asking for the reasoning or another learner’s view first keeps more people thinking.
How do these techniques work in an online class?
Use the chat for simultaneous answers, polls for multiple choice, and tell learners how long you will wait so silence is not mistaken for a technical problem.
