Short, practical things that work on Monday morning.
If your top level is the only respectable place to land, most of your class fails by design. Anchor the middle as the genuine target.
Productive failure needs a precisely calibrated task: solvable in part with what they know, unsolvable without what you are about to teach. Let AI calibrate it.
When accounts contradict, students pick a winner or give up. Historians treat the contradiction itself as evidence. Teach that move with a two-column matrix.
Students who explain a concept in their own words first learn more from whatever the AI says next. Order is the whole trick.
Breaks are not the problem; the ragged five minutes after them is. Decide the way back in before you let them out.
'Materials manager' is a title, not a role. Interdependence appears when the group genuinely fails if any one member's job goes undone.
Collect the work, pick one answer, put it under the visualiser, and let the class do the marking. One artefact, thirty people thinking.
You write for an hour; they read for a minute, if at all. Three minutes of live marking does what the margins never did.
A multiple-choice question earns its keep when every wrong answer tells you exactly which misconception produced it, and which repair comes next.
The last five minutes are usually spent packing bags. They are also the cheapest retrieval opportunity in the whole lesson.
A standing rule for every AI answer: one place it could be wrong, one way to check it, one non-AI source to consult.
Release the class to independent work too early and they spend twenty minutes rehearsing errors. Wait for a high success rate first.
