Question 1

What is NCEA AS 91612 about?

Accepted Answer

This is an externally assessed (exam-style) report worth 4 credits. Students write a report explaining how technological modelling — specifically functional modelling and prototyping — was used in a real technological project they have worked on. The report must show how modelling helped make good decisions at each stage of developing and then putting a technological outcome into use. Students also need to identify and discuss 'competing' and 'contestable' factors (things like ethical, cultural, sustainability or political considerations that influenced decisions), and explain how modelling helped resolve or respond to those factors.

Question 2

What do students need to do for AS 91612?

Accepted Answer

1. Write a formal report (with paragraphs, subheadings, and correct grammar) about a single technological outcome you developed. 2. Explain what functional modelling is and how you used it to test ideas and competing/contestable factors during the development phase. 3. Explain what prototyping is, how it differs from functional modelling, and how your prototype testing (ideally in the real environment it will be used in) informed decisions about implementation. 4. Define and correctly categorise competing factors (e.g. conflicting technical or design requirements) and contestable factors (e.g. ethical, cultural, sustainability debates), and explain how modelling helped you address them. 5. Include clear, legible photographic evidence of your functional modelling and prototype testing, and refer to those photos directly in your writing to support your explanations. 6. At the higher grades, reflect on and discuss how the evidence from modelling made your decisions informed, responsive, and defensible — meaning you can back them up with evidence.

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91612?

Accepted Answer

Achieved: You clearly tell the difference between functional modelling and prototyping. You correctly identify and categorise competing and contestable factors. You explain how functional modelling was used to test those factors and how that influenced your decisions during development and implementation. Merit: You back up your explanations with both written detail and photographic evidence. You explain specifically what changed during development because of what functional modelling showed you, and what changed because of prototyping results. You show how the competing and contestable factors were actively considered and addressed through your modelling work. Excellence: You write a thorough, reflective discussion — not just describing what happened, but explaining how the evidence from modelling justified and defended your key decisions at every stage. You weave the competing and contestable factors throughout your discussion, showing how they were resolved through modelling. Your report is concise, well-structured, and clearly your own authentic work.

Question 4

What mistakes do students typically make in AS 91612?

Accepted Answer

1. Not including a finished technological outcome at all. 2. Failing to explain the difference between functional modelling and prototyping — treating them as the same thing. 3. Not testing the prototype in the environment it is actually meant to be used in. 4. Writing descriptions of testing without including photographic evidence — photos alone or descriptions alone are not enough at higher grades. 5. Including photos, sketches, or diagrams but never referring to them in the written discussion. 6. Getting competing and contestable factors wrong — not defining them correctly, not distinguishing between them, or not connecting them to the modelling work. 7. Focusing heavily on risk management or stakeholder feedback instead of on modelling and decision-making (stakeholder feedback is not a form of modelling). 8. Using the correct terminology from the standard — like 'defensible decisions' or 'contestable factors' — without actually linking those words to real evidence from their own project. 9. Writing in a portfolio or bullet-point style instead of a formal report with paragraphs and subheadings. 10. Making the report too long by including a lot of information that is not relevant to modelling or decision-making.
