Question 1

What is NCEA AS 91886 about?

Accepted Answer

You need to show you understand how people interact with computers and other devices through their interfaces. This means explaining how a user interface (buttons, menus, touchscreens, etc.) actually works for the tasks people need to do, and identifying whether interfaces are well-designed by spotting examples of good usability practices.

Question 2

What do students need to do for AS 91886?

Accepted Answer

1. Describe how a chosen user interface helps someone do a specific task (what the user wants to achieve) 2. Identify and explain examples from a real interface that show good usability heuristics (design principles that make things easy to use) 3. Evaluate an interface by measuring it against usability heuristics to explain what works and what doesn't 4. Suggest concrete improvements by comparing how different interfaces handle the same task differently

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91886?

Accepted Answer

Achieved: You describe a user interface's role for a task and point out examples of usability heuristics at work in it. Merit: You evaluate an interface by judging how well it follows usability heuristics, explaining both strengths and weaknesses. Excellence: You suggest specific improvements to an interface by comparing and contrasting how other related interfaces solve similar problems better.

Question 4

What mistakes do students typically make in AS 91886?

Accepted Answer

1. Not naming specific usability heuristics or design principles when identifying examples—just describing the interface without explaining the HCI concept behind it 2. Failing to focus on the actual task users are trying to complete—describing the interface in general rather than how it helps with a specific purpose 3. Suggesting improvements without comparing to other interfaces or without showing why the change would actually be better based on usability principles
