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

[Robert Hallworth]

This is my spin on this

"Skills in using a programming language " this to me is a coding criteria so ..

Documentation is the internal documentation
Complex. I have told my students Quicksort

Sorting is a Science in itself and reasons for which sort to use get very complicated but it is easy to demonstrate that quicksort is usually more efficient than selection sort

I think this list pointed out  http://sorting.at/ does a good job of visually comparing sorts.
kind regards

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.
