Level 1 — Human-Computer Interaction
Teaching it? Start here: Kaiako run-sheet — what Achieved, Merit and Excellence actually look like, the chain to teach, and the week task by task. · Classroom deck (35 slides) — project it.
Unit hub for a Fraser placement class (CSC1), teaching from Task 6 onward under the class's associate teacher. Anchors every task built here against the real, verified achievement standard — not an assumed one.

The Standard
Demonstrate understanding of usability in human-computer interfaces.NZQA. Current approved standard, Level 1, 5 credits, external.
This is a Level 1, 5-credit, externally assessed standard — everything taught in this unit is exam preparation, not internal-assessment evidence gathering. Every task should build directly toward the exam, and it's worth saying that out loud to the class: this is not busywork, it's rehearsal for March–November.
The Achievement Ladder
The formal criteria and their explanatory-note movements should be named precisely:
Describe the purpose of human-computer interfaces and usability principles and their use.
Explain how usability principles are applied and explain usability in terms of those principles.
Compare interface usability and apply usability principles to suggest specific improvements.
What evaluation adds: a supported judgement about effectiveness, significance or suitability; a like-for-like comparison; attention to trade-offs; and a specific principle-grounded improvement. It is not simply a longer explanation.
Verified 2026 Assessment Overview
The 2026 specification confirms an end-of-year online digital examination with questions in short- or extended-answer format. Examination resources are supplied, including a list of Nielsen's heuristics, and candidates study an interface of their own choice beforehand. Examples will be drawn from Mātāpono Māori, Nielsen, internal/external consistency and accessibility.
The specification does not promise that the five-part structure, videos, scenarios or cut scores used in the 2024 and 2025 papers will repeat. Its 800–1200-word wording is guidance, not an 800-word minimum. Students should not assume their organiser, screenshots, notes or internet access can enter the external.
Usability Principles — Why the Unit Is Shaped This Way
The standard's explanatory notes name three example families a student can draw on, and the class sequence maps onto them. Mātāpono Māori are explicitly within the assessment scope alongside Nielsen's heuristics and consistency/accessibility. That does not make them identical or interchangeable kinds of knowledge, and it does not turn their assessment examples into complete definitions.
Tasks 3–6 in this class — the ten heuristics and the confusable pairs among them.
Accurate te reo Māori, spell-check support for te reo, and support for expressing tikanga and mātauranga Māori in an interface — Task 7 in this class.
Internal/external consistency and accessibility — folded through the heuristics work and explicit in Task 8 (accessibility in video games).
Cultural-integrity note (Task 7): these are Māori concepts whose meanings exceed their assessment use. NZQA gives examples that could be relevant to interface usability; it does not define the concepts through those features. They may illuminate interfaces used by diverse people, but they must not be redefined as generic English HCI qualities. Students test whether relationship, language practice, responsibility, authority and context are actually evidenced, without being asked to claim an identity they may not hold.
Task Sequence
Tasks 1–5 were already delivered by the associate teacher before this placement began. Built here from Task 6 onward, one task at a time, each anchored to the standard above.
Student Revision Pathway
The teacher pages above contain the reasoned keys. These linked student copies contain no answers and can be printed or posted directly.
Supplementary
A standalone, single-lesson introduction to Nielsen's 10 heuristics — built before this unit hub existed — covers the same ground as this class's own Task 3 (video + CS Field Guide + slides). Kept here as a condensed revision lesson or a fallback if a relief lesson on the heuristics themselves is ever needed, not as the primary route through the unit.
Every task built into this hub follows the same shape: a teacher lesson page with full pedagogy, timing and a reasoned answer key so it can be taught cold by anyone — and a separate clean student worksheet with no answers on it. That separation is deliberate: the printable resource is safe to hand straight to a class or upload to Google Classroom without editing.
