# Text-based Storyboard — The Mixed Classroom

> Kit 12 · The Mixed Classroom · deliverable · designed and built by I Wayan Usada · fictional vmbo-t class

## Design premise

Four moments from one school day, each with one or two students who need something different. Revised after the build so it matches the 2D coach and the 3D classroom; both read `classroom.js`. One barrier taxonomy is used everywhere: **speed, misconception, access, face** (the old 3D used visual/cognitive/physical/emotional).

## Per-moment structure

1. **Observe.** Each student in the moment shows behaviour, not a label (Amir flicking a switch; Yusuf's worksheet with 3/4 + 1/2 = 4/6).
2. **Diagnose.** Name the barrier for each student (1 point each). Feedback explains what the behaviour shows.
3. **Move.** Only after diagnosing: one move for the moment, from three (best 2, workable 1, harmful 0). Options are shuffled.
4. **Consequence.** In 3D, the students' posture changes (back to work, stuck, or withdrawn) and the lesson clock loses 3, 6 or 9 minutes.

## Moment plan

| Moment | Students → barrier | Best move | Workable | Harmful |
|---|---|---|---|---|
| Electricity, 25 min left | Amir → speed · Sanne → face | Extension question for Amir; 90 seconds with Sanne on the first wire | Amir tutors Sanne | Public praise for Sanne's copying; tell Amir to sit still |
| Fractions, 12 min left | Yusuf → misconception · Eline → speed | Yusuf's answer, anonymously, as the class argument; "prove it with a drawing" for Eline | Give the rule; harder sums | Move on to tomorrow's topic |
| Persuasive letter, 20 min left | Milan → access (transcription) · Fatima → misconception (genre) | Scribe one paragraph for Milan; 15-second conference with Fatima | Extra time; checklist | Laptop for Milan; leave Fatima |
| After the test, 40 min left | Jason → face | Short public answer, private specific conversation about one pattern | Ignore, return tests at the end | Mention his result in public (**critical**) |

## Scoring and pass rule

7 diagnoses + 4 moves × 2 = 15. **Pass = 11 or more, at least 5 of 7 barriers named, and no public exposure of a failed test.**

## Debrief

Each student's barrier and your diagnosis; the pattern (speed → harder question in the same task; misconception → argue with it; access → remove the barrier; face → privacy); a "try it tomorrow" task. The typo "soms" in moment 4 is corrected to "sums".
