Codes: AC9S7I08, AC9E7LA04, AC9E7LY06, AC9AMA8C01. Goal: structure a short visual/text/audio-described explanation of a model key and its limits. Prepare: blank explanation storyboard, Version 2.
- Open · 3 min. Name a younger/new reader who was absent; no actual younger child is asked to test it.
- Model · 5 min. Four-panel order: what the model is → first decision → full-profile check → what “unmatched” means. Say why an overview and concluding limit help navigation.
- Investigate · 8 min. Learners inspect the two different claims “T3 reaches S3 in V1” and “T3 is S3.” The first reports a trace; the second omits the mismatch. Evaluate using source traits.
- Choice · 10 min. D14-A/B/C: text storyboard, low-ink visual layout with alt script, or 40-second spoken/AAC script. Each has accurate rule, source ID, reading order and scope limit.
- Check · 6 min. Swap with one peer or use a self-blind step-through: can another reader tell what to do with T4? Revise an ambiguous line. Record whether actual peer feedback occurred.
- Note · 3 min. Save first and revised line; plan a specific next clarity test. Do not score voice, accent or drawing polish as classification evidence.
Later/home: Draw four boxes on scrap or dictate the panels; no recording or public upload required.
