The DCAT External
The DCAT (Digital Controlled Assessment Task) exam set by NZQA, but held during normal school time at the start of Term 4 - before study leave.
Exam papers are marked by NZQA and so this is an external assessment.
External 1.10: AS91886 : Demonstrate understanding of human computer interaction
- 3 credits
Candidates may be asked to refer to specific usability heuristics (from Jakob Nielsen’s 10 Usability Heuristics for User Interface Design).
What is Human Computer Interaction (HCI)?
Human Computer Interaction (HCI) - Looks at how Humans use or interact with computer Technology . Computers were Designed to help humans do tasks faster, or more accurately. This is why how humans behave and brains work is an important part of computer science
What if people acted like computers?
CS Field Guide's HCI Video
Developed by Canterbury University, it contains a lot of excellent resources.
There are two Chapters in the CS Field Guide on HCI which you should read:
What is UX Design?
User Interface (UI) - The means by which the user and a computer system interact, in particular the use of input devices and software. The same basics of interface design are used across user interfaces to help users get to grips with things faster. It is apart of a boarder term user experience. A design is not usable or unusable by itself. It is the features together with what the user wants to do with it and the users environment, that decide the usability.
User Experience (UX) - The overall experience of a person using a product such as a website or computer application, especially in terms of how easy or pleasing it is to use.

Heuristics
Are rules or methods that come from experience. They are often known as "rule of thumb'. In HCI, heuristics are a list of guidelines we can use to help us evaluate a user interface. One of the best known are Jakob Nielson's 10 Heuristics which are explained below.
T-shaped literacy Resources below - use the posters, videos and/or slideshows to learn the 10 Heuristics.
Usability Heuristics Videos from Jakob Nielson
Usability Heuristics Slideshows from online course
In the exam at the end of the year you will have to be able to:
define all 10 heuristics.
identify & describe how they have been used in an user interface.
describe how they could have been used to improve the interface.
Complete the following activity to:
help you learn the 10 heuristics.
gain a greater understanding to be able to apply them in your own interface design.
If your Teacher has setup a Google Classroom Assignment containing a Google Slide template - use that.
OR create a Google Slide with the title: 11DTEC HCI then attach it to the Google Classroom assignment.
Your presentation will cover all 10 heuristics.
Make the theme appealing as using colours and images will help you remember things.
If you have preferred way of presenting the information that is fine too - turn that in on completion instead.
You must have a title slide.
Then for each Heuristic you need to:
Give it a heading (the name of the heuristic)
Give it a definition in your own words not the words of others/online
Give examples (at least three) of the heuristic being used in an website, use screen shots and explain how they have improved the usability of the site.
Explain improvements that could have been made to the interface and compare/ contrast it to other interfaces
Turn it in to Google Classroom when you are finished.

--- HELPFUL COMMENTS FROM THE LAST FEW YEARS ---
This standard provided clear opportunities for students to attain grades at achieved, merit and excellence, using the describe, explain and discuss model. The resource sheet enabled candidates to focus on identifying and evaluating the application the heuristics.
Overall, candidates' performance in 2021 improved, with a high percentage of candidates attempting all parts of the task. A large number of candidates presented reports showing considerable insight and passion.
A shorthand list of the heuristics is provided as an aide-memoire for candidates, who are meant to understand the implications of these. Candidates who had not prepared adequately for the assessment struggled to use the literal meaning of the listed heuristics to try and answer the questions.
Most candidates described the role of their chosen interface and were able to identify and describe four heuristics.
Some candidates showed a weak or partial understanding of a number of heuristics (user control and freedom, flexibility and efficiency of use, and the two error-based heuristics, error prevention and help users recognise, diagnose and recover from errors.) which meant they were limited their ability to demonstrate evidence at a higher grade.
Those candidates who compared their chosen interface to a second video that was provided generally did better in the comparison as they could use screenshots to illustrate their point.
Some candidates who attempted part (c) did not make an evaluation. A response that was merely adding further evidence of the type already supplied in the description tasks in parts (a) and (b) meant that the response was not at merit or excellence level. Evaluation, however, continues to be poorly understood by some candidates. Some candidates simply repeated the answers to previous questions using different words or provided a score (e.g. ‘I would give Visibility of System Status a 9/10’). This is not sufficient as it needed to be justified with examples.
In part (d), the task requiring a discussion of improvements, some candidates failed to mention the heuristics that they were talking about. Some candidates spoke about heuristics without supporting evidence, which made it difficult to determine their level of understanding.
