Hi Sandra,

I can't find the thread on the 29th Sept - was that a statement from VCAA?

My 2c - and it may just be worth that - is that if it's in the study design
- it's in. There would be no reason to include it if there was no intention to examine it or if it served no purpose. I feel like the use of the word 'or' is because the terms are synonymous (I suppose!). I think perhaps the dot point could have been written differently if this was the intention?

Cheers,
Adrian

Hi Sandra

I asked this at the end of 2015...

*"Maybe someone can help with this, or it might require Paula.In SD U4O1
KK2 it refers to "uses of data structures to organise and manipulate data, including associative arrays (or dictionaries or hash tables)"I'm not sure how to interpret the 'or's after 'including'. Does it mean"- dictionaries and hash tables are synonyms for associative arrays?- we may choose between dictionaries and hash tables and associative arrays?Neither of those makes much sense.  What does it mean in terms of teaching KK?"*

There was no reply from VCAA.

You said that "hash tables were listed as something that not all students had to know".
Who listed that? If it wasn't VCAA, it was an opinion, but not canonical.

As I've said before publicly on this list, my understanding is that all 3 terms (assoc arrays, dictionaries, hash tables) are *synonyms* from VCAA's POV.
Since VCAA has not contradicted this, I can only assume it's true.

Regards,
Mark
