[Year 12 SofDev] Query about marking SAT 2 criteria 6

[Paragreen, Chris J]

Hi Vi,

I'm interpreting complex as meaning they code their own sort. Non-complex will be to use the internal sort function.
As for documentation, at the SAT day at VCAA it was mentioned that they don't need to go into big O notation (although for the top mark in this category I think that would be my discriminator), but they would need to provide some qualitative statements as to why the algorithm they chose was suitable for their particular application. Also discussed at the VCAA meet was that the "documentation" could be in the form of internal documentation (but did not have to be).

Regards,

Chris

Hi all,

  I'm not sure if it has been answered on this edulist, but I have a question about marking Criteria 6 where it states "Documents the efficient use of a complex sorting algorithm in the solution".



>From my interpretation does this mean that students HAVE to use a sorting algorithm (they can choose from insertion, bubble, selection or quick sort? )



Complex means - they can only choose from selection and quick sort ( and not insertion or bubble sort)?

Document means - they need to explain and justify why they used the particular sorting algorithm? In terms of time complexity and usage of memory space?



I was wondering how others are marking this criteria.



Thank you.
