The Concept

Adaptivity & Routing

What actually drives the adaptivity — a small, reviewed routing table rather than something open-ended. The result of the lesson's check, not a score, decides what is offered next, and the learner makes the choice.

Participatory adaptivity & agency

The governing frame is transparent, by-choice adaptivity: read the result → say it plainly → offer options → the learner chooses. The system marks one option as Recommended, shown first with a deep border, and offers the rest beside it. The learner's choice is recorded as an agency signal — evidence of engagement, not noise. Because the recommendation is always visible, agency never becomes abandonment.

The routing table

The routing table is data, reviewed like content, and it is the only place the "what do we offer" rule lives. The routing decision is not pass/fail — each result opens a different set of options:

Result	Options offered	Recommended	Least to move on
Solid	Continue	Continue	Already met.
Nearly there	Continue · firm it up with one example	Continue	Nothing extra; Next lesson is free.
Not yet	See it another way · walk through a worked example · continue	See it another way	Nothing extra; Next lesson is free.
Not sure	See it another way · walk through a worked example · continue	See it another way	Nothing extra, and no penalty for the honesty.
A mix-up	See it another way · rewatch the part · practise again · show your thinking again	See it another way	One try at any option before Next lesson.

On Nearly there, Not yet and Not sure, a fresh question joins the options once the learner has taken one of the support steps; on a mix-up it is offered from the start. On Solid it is never offered — the idea is already met.

The options

Option	What it opens
See it another way	A second way in to the part the check tested, produced in Studio for that part. On a mix-up it is marked "made for this mix-up" only when it targets that misconception.
Firm it up with one example	The lesson's own firm-up prompt; the learner writes one example in their own words. It is kept, never marked.
Walk through a worked example	A click-to-reveal walk through one approved variant of the check: the story, the right verdict, why (from the rubric), how a sound justification reads — then "Try one yourself".
Rewatch the part · Practise again	The lesson itself, opened at the tested part's video or reading, or at its Try it. No new content is needed.
Show your thinking again	A fresh question: an unseen variant of the same check. At most two per lesson, enforced on the server.
Continue	The next lesson.

Every option draws on pieces Studio produced and reviewed for that lesson — the mix-up message, the second way in, the firm-up prompt, the worked example and the look-again probe. Publishing refuses a lesson missing any required piece, so no learner page can arrive without its options.

A mix-up: one try first

When a result matches a named misconception, the card shows its approved label and the mix-up message written for it: what the learner said, why it misses, and the idea seen correctly. Then "Next lesson" appears after one try at any option — see it another way, rewatch, practise again, or a fresh question. Passing isn't needed; until then the page says so plainly. Leaving by the back link or the course page stays possible; only "Next lesson" waits. Every other result keeps Next lesson free.

The Revision page

Ideas that need another look don't vanish; they gather on one Revision page per course, open any time. It is a course tab (with a count) and also a Revision hub in the main menu that lists the learner's courses. Every item says where it came from — "From lesson 3 · … · open the lesson" — and the link opens that lesson. Items come in four kinds:

Item	What the learner does
Look again at your answer	Reads their own earlier answer, quoted as written, and answers one question: "What would you change in this answer, and why?"
Try the lesson's check	Opens the lesson straight at a check they skipped, then returns here.
One example	Writes one example in their own words. Kept, never marked.
A fresh question	Answers an unseen variant of the lesson's check.

Feedback says right or not yet in words — never a score, never a result name — and offers the lesson when it helps. "Short on time?" offers 5 minutes, 10 minutes or Everything: the server picks the items that fit, required first, then mix-ups, then the oldest; the rest stay for next time.

Before Milestone N

When a milestone is open or comes next, its required items show first on the Revision page as "Before Milestone N". The rule is deliberately light:

• Each required item needs one honest try before the guide's Start assessment unlocks. Passing isn't needed.
• At most five rows show at once, required first; "+N more after these" appears when there are more, and the next row appears as each is tried.
• Skip moves to the next row but doesn't count as a try.
• The Milestone Guide is readable at any time. Until the tries are done, its button reads "Start opens after Revision · N left" and links back here.

Every way out of the page goes to the guide, never straight into the assessment. The milestone itself is visible on the course road from the start; only Start waits.

"Welcome back"

Before the first lesson of a new day, when something is due, the learner meets one short look-back: one item, about a minute, never marked. Any honest answer moves them on to their lesson. It is required, but narrow:

• Only starting the next lesson waits for it. It never blocks the course page, the guide, results or Revision.
• Each idea gets the look-back once; if it is still open afterwards, it waits on the Revision page.
• It never appears on the same day the item opened.
• There is no deferral and no ignore counting.

Personalised assessment context

For milestone work, the rubric and standard stay identical for all learners, but each learner chooses a world — a context for the brief, with its own situation, audience and files. Same rigour, different context. This is an adaptive mechanism and an integrity mechanism at once, because a shared answer no longer fits another learner's world (see Lessons, Checks & Milestones).
