SD C4 video page: add active-viewing scaffolds (focus Qs, pause-and-predict, CYU, watch-with-artefact)
Interpolated retrieval + pre-questions to counter passive viewing; pause timestamps anchored to the actual video content.

Watch in order. Each video pairs with one assessment package.

> [!TIP]
+
> **Don't just press play.** For each video: read the **🎯 Watch for** line first, keep the **✍️ While you watch** artefact open beside you, hit pause at the **⏸** marks to predict before the narrator answers, then do the **Check Your Understanding** questions from memory. Unfold (`▸`) only after you've answered.

## 1. Design Ideas — C4-1
VCAA Criterion 4, Indicator 1 · Design defence presentation with your printed design pack
+
**🎯 Watch for:** this video reframes the assessment as a *design studio pitch* — you're the junior designer, your teacher is the client. Listen for the one sentence-shape that proves you've *justified* a decision rather than just described it.

What you'll learn: how to use the four ideation tools (mood boards, brainstorming, mind maps, sketches) plus annotations to produce a defensible design pack, what the design defence presentation looks like on assessment day, and the trade-off language ("considered X / chose Y / because Z") that separates 7–8 from 9–10.
+
**✍️ While you watch:** have your design pack open. Pick one decision in it — a layout, a colour, a flow — and write a single sentence defending it as the video shows you how.
+
+
**⏸ Pause and predict**
+
+
- **1:50** — You've just heard the five artefacts (ideas list, mood board, brainstorm, mind map, annotated sketches). Predict: are these five copies of the same thing, or something else?
+
>| Five *different lenses on the same design problem* — not duplicates. Each tool views the one design from a different angle.
+
+
- **5:05** — A student has a strong design pack but pitches it vaguely. Predict the highest band they can reach.
+
>| A middle band only. "The pack sets the ceiling, but the pitch confirms the level" — you can't claim top marks for decisions you can't defend out loud.
+
+
**Check Your Understanding**
+
+
1. In one sentence, what's the difference between an annotation that *describes* and one that *justifies*?
+
>| Describing says how something looks or works; justifying names an alternative you rejected and gives the reason.
+
+
2. A student's pitch is fluent and confident, but their design pack is thin. Can they reach 9–10? Why or why not?
+
>| No. You can't defend artefacts that don't exist — the pack is the *floor* of the evidence, and the pitch only confirms the level the pack already supports.
+
+
3. Fill in the trade-off sentence shape examiners listen for: "I considered ___, I chose ___, because ___."
+
>| considered **X** / chose **Y** / because **Z** — naming the rejected alternative is what lifts a decision from *describe* to *justify*.

VCAA Criterion 4, Indicator 2 · Written evaluation test with your printed evaluation outline and design pack
+
**🎯 Watch for:** this video reframes C4-2 as writing a *product review* (think Choice or Wirecutter). Listen for the difference between an *explain* statement and a *justify* statement — it's the single highest-leverage move in the rubric.
+

What you'll learn: how to write measurable evaluation criteria linked to your SRS, the three VCAA-prescribed efficiency measures and eleven effectiveness measures, how to apply criteria in a matrix, and the explain-vs-justify distinction (and why "naming the rival" is the 9–10 differentiator).
+
**✍️ While you watch:** have your SRS and evaluation outline open. Take one vague criterion (e.g. "easy to use") and rewrite it as a measurable test as the video shows you how.
+
+
**⏸ Pause and predict**
+
+
- **2:46** — The narrator says a good matrix needs *both* columns. Predict: what do you miss if you score only effectiveness? Only efficiency?
+
>| Effectiveness-only: you don't know if the software actually *runs* well (speed, resource use). Efficiency-only: you ignore whether it actually works for the *humans* using it.
+
+
- **3:33** — "The design must be user-friendly." Predict how you'd turn this into something you could actually score.
+
>| Give it a measurable test — e.g. "a new user completes the core task in under 90 seconds, unassisted." If you can't point to what you'd look at, you can't measure it.
+
+
- **8:15** — A student explains why Design A scores well but never mentions Design B. Predict the highest band they can reach.
+
>| Capped at 8. To reach 9–10 you must *name the rival* — weigh the competing design and explicitly accept the trade-off.
+
+
**Check Your Understanding**
+
+
1. What three parts must every evaluation criterion contain?
+
>| A **name** (what's measured), a **link** (to a specific SRS requirement), and a **measure** (the concrete, testable way you'll check it).
+
+
2. Which column holds *speed of processing*, and which holds *usability*?
+
>| Speed of processing → **efficiency**. Usability → **effectiveness**. VCAA names **3** efficiency measures and **11** effectiveness measures. See [Efficiency vs Effectiveness](/sd/C04/Efficiency%20vs%20Effectiveness).
+
+
3. The matrix and the recommendation paragraph evidence different band ranges. Which is which?
+
>| Matrix = the **floor**, evidences bands 1–6. Recommendation paragraph = the **ceiling**, evidences bands 7–10. You need both.
