Assumed-context reconstruction

Work out what a text expects you to already know, and get that first.

When to use this: When something feels wrong
Learning impact: Reliable gain
Learning evidence: Credible with caveats
Where you are with the topic: Meeting the idea
How often to use it: Worth repeating often

When to use it

A passage feels hard and you suspect missing assumed knowledge, not mysterious ideas.
You keep rereading the same paragraph and vocabulary is not the real problem.
A text expects arguments, events, or conventions you never got.

What to ask AI

Type something like: "Here's a passage I'm finding hard [paste]. Don't explain it. Instead: what does this assume its reader already knows, terms, prior arguments, events, figures, conventions? List them. Then tell me which two gaps would unlock the most."

Forbid a paraphrase lecture until assumptions are listed.

Keep the hard part on your side: you fill the top gaps, then reread.

How it helps

Difficulty is often missing references, not opaque genius.

Assumed-context reconstruction recovers what the text expects you already know so you can learn those pieces on purpose.

It is prerequisite diagnosis applied to a reading.

How to run it

Paste the hard passage.
Ask for assumed knowledge only, no explanation yet.
Rank which gaps unlock the most.
Fill those gaps from real sources or earlier chapters.
Reread the passage and only then ask for clarification of what remains.

Example exchange

You

Here's a passage I'm finding hard. Please do not explain it yet. What does it assume I already know, terms, prior arguments, events, figures, conventions? Which two gaps would unlock the most?

It assumes the Prisoner's Dilemma payoff structure, Nash as an equilibrium idea, and a prior section's definition of dominance. For you, the top unlocks are payoff-matrix literacy, then Nash in one sentence. Fill those, then paste the passage again.

You

Filled, here's my one-sentence Nash, and the matrix I drew.

Good. Now reread. What still blocks you, if anything, in one line?

Copyable prompt

Here's a passage I'm finding hard [paste]. Don't explain it. Instead: what does
this assume its reader already knows: terms, prior arguments, events, figures,
conventions? List them. Then tell me which two gaps would unlock the most.

The Tell

Here is how you know this method has flipped: you got an explanation of the passage and still cannot name what it was assuming.

The AI lectured; you never recovered the missing context.

Principle evidence

Strength of the underlying learning idea, not a claim about AI products.

The underlying learning idea is rated moderate. Prerequisite diagnosis, scaffolding, and schema activation all support recovering what a text expects you already know.

AI delivery evidence

Whether an AI tutor delivers this method well is a separate question.

AI may mis-guess your gaps. Treat the list as hypotheses; confirm against your course. Delivery accuracy is speculative.
