Write the hinge question for tomorrow's lesson

Write the hinge question for tomorrow's lesson

Twenty-five minutes into the lesson and you cannot tell if the class has actually got it. Every teacher has a way of handling that moment, and most of the ways are bad. Thumbs up, thumbs down, "any questions", whoever's hand goes up first. None of them tell you what you need to know. A hinge question does. It takes ten seconds to run in the room, and about fifteen minutes to write properly, which is why so few of them get written on a Tuesday night. This prompt cuts the write time to ninety seconds.

The prompt

You are a senior [SUBJECT] teacher in an Australian [PRIMARY / SECONDARY / TERTIARY] school with a working grasp of formative assessment in the Dylan Wiliam tradition. You know that a hinge question is not a comprehension check and not a retrieval question. It is one diagnostic multiple-choice item, sat at the pivot point of a lesson, that meets four tests:
1. Every student can attempt it in under a minute.
2. The response makes the misconception, not just the wrong answer, legible to the teacher.
3. There is only one defensible correct option, so scoring the room takes ten seconds.
4. If more than a third of the class miss it, the teacher has a specific reteach move ready.

Draft me one hinge question for tomorrow's lesson.

CONTEXT
- Year level: [YEAR LEVEL]
- Subject and unit: [e.g. Year 9 Science, unit on cellular respiration]
- Curriculum frame: ACARA v9.0 [PASTE the specific content descriptor], or the state study design line
- Lesson objective in one sentence: [e.g. students distinguish photosynthesis from respiration as opposite but not mirror-image chemical processes]
- Where in the lesson the question lands: [e.g. after the worked example, before independent practice, roughly the 25-minute mark]
- The pivot concept, in one sentence. The one thing students must be able to do before I let them move on. BE SPECIFIC. Not "understand respiration". Yes "correctly identify which of two chemical equations represents respiration, and explain in one sentence why the other one cannot".
- Common misconceptions I already know about for this topic: [LIST 2 or 3 if you can. If you cannot, write "unknown, please supply the usual ones for this year level".]

PRODUCE, IN THIS EXACT ORDER. NO PRE-AMBLE. START WITH SECTION 1.

1. THE HINGE QUESTION. One stem, four options labelled A to D. Under 40 words for the stem. No reading passage required. Answerable in under a minute with a pen and paper or a raised hand.

2. THE CORRECT ANSWER, with one sentence explaining why it is the only defensible option. If two options are defensible, rewrite the question. Do not soften this rule.

3. THE DISTRACTOR MAP. For each incorrect option, one line naming the specific misconception a student holds who would pick it. Not "does not understand the concept". Yes "believes plants only photosynthesise during daylight and therefore reads Option B as a whole-cell process".

4. THE READING OF THE ROOM. Two lines. First line: what I do if more than two-thirds of the class get it right. Second line: what I do if more than a third get it wrong. Both moves are specific. The words I say, the follow-up worked example, or the next question I ask. Not "review the concept".

5. THE COVERAGE CHECK. One line naming a common misconception this hinge does NOT catch, plus the follow-up question I would use for it if I had another two minutes.

RULES
- Australian English throughout. Year 9, not 9th grade. Australian curriculum vocabulary.
- No em-dashes and no en-dashes anywhere. Commas and full stops only.
- Do not use "engaging" or "meaningful learning experience".
- Do not open with "great question" or "here is a strong hinge item". Start with Section 1.
- Do not add extension activities I did not ask for.
- If the pivot concept I gave you is too broad to hinge on in one question, say so in a single sentence at the end and suggest a narrower pivot. Do not silently narrow it yourself and pretend that was what I asked.

What it does well

The four-part filter (Wiliam's original tests) is what stops the output being a generic multiple-choice question dressed up as a diagnostic. The distractor map is the real deliverable. It is the difference between an MCQ and a hinge question, and it is what makes the ten-second scan of the room actually mean something.

Where it falls over

The output is only as good as the pivot concept you feed it. "Photosynthesis" produces a bad hinge. "Students can identify which of two equations represents respiration and say in one sentence why the other one cannot" produces a good one. The prompt asks for that sentence specifically, so if you skip it or write it loosely, the whole thing collapses.

The model will also occasionally write a distractor that is only wrong because of a word choice, not because it reveals a wrong idea. Eyeball the distractor map before you print. If a distractor does not map to a real misconception a real student would hold, rewrite it or bin it.

Try it like this

For Year 8 Maths on equivalent fractions: the pivot is "students can identify which of two fractions is larger without converting either to a decimal". The hinge lands after the visual model and before the worksheet.

For VCE English on textual analysis: the pivot is "students can name the difference between describing what a text does and describing what a text is about". The hinge lands after you model the analytical opening and before students write their own.

For Year 5 History on primary sources: the pivot is "students can identify which of two sources is closer to the event, given only the source, the date, and the author's role". Here the hinge is the whole exit ticket, and the follow-up move is Wednesday's do-now.

If you write only one hinge question this week, put it in the lesson where you least trust your read of the room. That is where the ten seconds pay for themselves twenty times over.
