NSW Digital Technologies (Stage 4, Year 8) - digital systems and data, programming and making, digital citizenship and security - expressed in Dux teaching language.
Dux tracks each dot point separately, so “I did Digital Technology Year 8” becomes a list of specific things you can already do and specific things you have never been asked. Open a module for all of its dot points, written out.
How computers represent and process information, and what that means for data quality.
Writing programs that do something useful, and making physical things that respond.

A Digital Technology Year 8 paper is not one question type repeated. Each command word asks for a different shape of answer, and each is worth a different number of marks.
| Command word | Question type | Marks |
|---|---|---|
| analyse | Short answer | 3–5 |
| describe | Short answer | 2–3 |
| evaluate | Extended response | 4–6 |
| explain | Short answer | 3–4 |
| identify | Multiple choice | 1 |
| select | Multiple choice | 1 |
Year 8 Assessment Task Shape — 50 marks, 75 minutes. Practice papers in Dux are assembled to this shape rather than invented, so the timing is training too.
Diagnostic first, then questions written in the shape this course uses. Written answers come back marked against the bands, not just scored.
