Get a concept explained at the exact level where your understanding actually breaks down
Diagnoses which prerequisite idea you're actually missing before explaining a confusing concept, so the explanation targets the real gap instead of restating the textbook at you.
The prompt
Ready to copy — highlighted parts are example details you can swap.
You are explaining a concept I'm stuck on, but before you explain anything, you need to find out where my understanding actually breaks down — not assume I'm starting from zero and not assume I have every prerequisite either.
CONCEPT I'M STUCK ON
Why torque is a vector, not just a magnitude
WHAT I ALREADY TRIED TO UNDERSTAND IT FROM
My physics textbook's chapter 9 section and the professor's slide deck
WHERE IT STOPPED MAKING SENSE
It made sense until they used the right-hand rule to say the direction is out of the page, and I don't understand why direction even applies to a twisting force
MY COURSE LEVEL
Intro physics for engineers, first-year college, calculus-based
STEP 1 — DIAGNOSE
Based on where I said it stopped making sense, name the single most likely prerequisite idea I'm missing or misremembering — be specific about which one, not a general "you need more background." Ask me one short question that would confirm or rule out that specific gap before you explain the main concept. Wait-style: state the question clearly as something for me to answer, don't just assume the answer and barrel ahead.
STEP 2 — EXPLAIN (only after stating the diagnostic question)
Give a provisional explanation that assumes the most likely gap is real, built in this order: the prerequisite piece first, stated in one or two sentences; then the concept itself, connected explicitly back to that prerequisite ("this is why that first piece matters"); then one concrete worked example at my course level, not a toy example simpler than what I'll actually be tested on.
WHAT NOT TO DO
Do not just restate the definition from My physics textbook's chapter 9 section and the professor's slide deck in different words — if my source already gave me that definition and I'm still stuck, repeating it reworded is not an explanation. Do not pile on three alternative explanations or three different analogies; pick the one path most likely to fix the specific gap you diagnosed and commit to it.
OUTPUT FORMAT
1. Diagnostic question (one sentence).
2. Provisional explanation (prerequisite -> connection -> concept -> one worked example).
3. One check-your-understanding question I should be able to answer if this landed.Customize
Optional — swap in your own details for the highlighted parts above.
Why this works
Most concept-explainer prompts just ask a model to "explain X simply," which produces a generically simplified restatement of the same source material the student already read and got stuck on — GPT-5.1 defaults to reorganizing available information rather than identifying what's actually absent, so without an explicit diagnostic step it will happily re-explain the definition in slightly different words and the student stays stuck at the same point. Forcing a diagnostic question before any explanation changes the task from "simplify this text" to "identify a specific missing prerequisite," which uses the breakdown-point detail as a symptom to reason backward from, the way a tutor would ask a clarifying question rather than launching into a lecture. Ordering the explanation as prerequisite-first, then explicit connection, then concept, then a single worked example at the stated course level matters because it mirrors how conceptual gaps actually cascade — a student who is stuck on torque's directionality is very often actually missing how the right-hand rule encodes rotation direction as a vector, and no amount of rephrasing torque itself fixes that; the model has to be forced to consider the layer beneath the stated confusion, not the confusion itself. Restricting the explanation to one worked example rather than several analogies matters because GPT-5.1's default instinct when uncertain about what will land is to offer multiple framings, which fragments attention and gives an unfocused student three half-understood models instead of one solid one; committing to a single path forces the diagnosis to actually be used rather than hedged around.
What you get back
Diagnostic question: Do you understand why a force applied off-center (not through the object's pivot point) makes something rotate rather than just slide? Provisional explanation: Torque isn't a new kind of force — it's how we measure a force's twisting effect, which depends on both how hard you push and where you push relative to the pivot. Because that twisting effect has a specific rotational direction (clockwise vs counterclockwise, or in 3D, an axis), we represent it as a vector using the right-hand rule: curl your fingers in the rotation direction, your thumb points along the torque vector...
