The Data poster

jiào xué xiāng zhǎng — “Teaching and learning grow one another”

The one widget that spends credits, and the one whose contents depend on your seat — including why a refusal costs nothing.

Not what you were looking for?

The Data poster turns what your learners have actually done into a picture for a slide. It is the one widget on the board that spends credits and the one whose contents depend on your seat, so it is worth knowing what it will and will not put on the page before you press it.

Without a plan: none

Needs an account, and 50 AI credits. Figures about learners are withheld without a teaching seat.

What it makes

You pick a title and a few things to put on it — a learner, a circle, a skill, a stretch of time — and it generates a poster-style image built from the real figures behind those things. It arrives on the slide as an image widget, exactly as an upload of your own would.

It is in the Basics group of the widget library, which is why tutors meet it early, and it needs an account: it reads your learners’ data, and a signed-out visitor has none.

What goes on it depends on your seat

This is the part worth reading before the first attempt. When the poster is built, every figure you asked for is resolved against who you are — and an author without a teaching seat gets figures withheld rather than a different poster.

That is the same rule as everywhere else on this site: what you can see about a learner depends on whether you teach them, and a picture is not an exception to it. A poster is a way of displaying data you already have access to, never a way of obtaining some.

  • Not enough practice yet — The figure exists but too little work stands behind it to report. Set some work and come back — this is the commonest reason on a new circle.
  • Not your circle — You asked for something about learners you do not teach. Nothing is shown, including the fact of how much there was.
  • Too few learners for a median — Group figures are withheld below the anonymity floor, because an average over three or four people identifies them individually.

Asking for the same poster twice

An identical request comes back from cache and is not charged again. So regenerating the same poster because you lost the slide is free; changing the title, the style or what is on it is a different poster and is charged.

There is also an hourly limit per account — generous for a lesson, tight enough that nobody can run a script against it.

Using it well

  1. Decide what the slide is for first — A poster is a thing you talk over for a minute. One finding reads; six figures do not.
  2. Pick figures that will not be withheld — Something a circle has actually practised, over a window long enough to contain work. A brand-new circle has nothing to show and a poster cannot invent it.
  3. Read it before you present it — It is generated, so check the figures say what you think they say. They come from your data, but the picture around them was written by a model.
  4. Keep the slide — The poster is an image on the slide. The board is saved, so it is still there next term — and regenerating the same one costs nothing.

What it will not put on a poster

Nothing a teaching view would not show you anyway. No text a learner typed, no cognitive-probe results, no ranking of children — the last one not because it is filtered out of the poster, but because no rank is computed anywhere to put on it.

And nothing about learners outside your own circles, at any granularity, including as part of a comparison.

Common questions

No. The check for "is there anything usable here" runs before the charge, so a refusal costs nothing. The reasons it gives are the actionable ones — not enough practice, not your circle, too few learners.
