Question 1

What is NCEA AS 91372 about?

Accepted Answer

You need to create a detailed plan (not actual code) for a complex computer program that solves a specific problem. Your plan must show how the program is organized into separate modules, how data will be stored and used, and how you'll test whether it works correctly. Think of it as a blueprint that explains the program's structure before any coding happens.

Question 2

What do students need to do for AS 91372?

Accepted Answer

1. Define all the variables you'll need, including what type they are (numbers, text, etc.) and where they can be used (just in one part of the program or everywhere) 2. Plan an indexed data structure like an array or list to store multiple pieces of related data 3. Break the program into separate modules (smaller tasks), explain what each module does, and show how they connect together 4. Describe the logic inside each module using sequential steps, conditional branches (if/then), and loops 5. Create a list of test cases including normal inputs, edge cases (boundary values), and unusual situations that might break the program

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91372?

Accepted Answer

Achieved: You construct a basic plan that includes variables with their types and scopes, an indexed data structure, a modular structure with details of how modules work together, and a set of test cases for the program. Merit: You skilfully construct a plan by working independently, choosing appropriate variable scopes that fit how they're used, selecting good parameters for each module, and including both normal and boundary test cases. Excellence: You efficiently construct a plan where modules form a well-organized breakdown of the task, variables and values are used smartly to make the program flexible and reliable, and your test cases cover normal situations, edge cases, and exceptional scenarios that might cause problems.

Question 4

What mistakes do students typically make in AS 91372?

Accepted Answer

1. Not clearly specifying the scope of variables—students forget to declare whether variables should be global (usable everywhere) or local (usable only in one module) 2. Missing or poorly designed indexed data structures—students either forget to include arrays/lists entirely or don't explain how they'll be used in the program 3. Vague module descriptions—students don't clearly explain what each module does, how they connect, or what parameters they need, making the plan hard to follow
