[Informatics] Informatics Performance Descriptors Question

[Mark]

Hi Alan

Perhaps:

- Primary:      Interviews, surveys, questionnaires. (These are the Big
Three)

- Secondary: Searching the internet, looking up encyclopædias, searching
newspaper archives, using Google Trends
<https://trends.google.com.au/trends/>*. (Many others exist**)

BTW - A warning to gentlefolk out there. Don't just read the *highest*
levels of performance in the assessment criteria rubrics.
Sometimes, important criteria appear in *lower* levels of performance and
are *not repeated* in higher level descriptions.
In particular, I refer to SAT criterion 3 that Alan quoted. Please refer to
the screenshot below.

Notice how the descriptor of the *highest* level of performance does not
include any reference to the need for *qualitative and quantitative data* -
a need that *was* mentioned in the two *lower* levels (5-6 and 7-8).  If
one only read the HIGH descriptor, this requirement would not be obvious.

This, I believe, is a dangerous practice that VCAA needs to fix in its
assessment criteria: any major requirement given in a *lesser* level of
performance should be repeated in all *higher* performance level
descriptors.

* For example, the rise of cat videos over time
<https://trends.google.com.au/trends/explore?date=all&q=cats%20videos>.

** I'd like to add that the usual sticky points that arises here.
If one just *repeats* the data in the secondary source (e.g. This article
says that 19% of men in 1985 owned a..."), it's a secondary source.
However, I would argue that if the harvested secondary data were used to
create *new* data, the new data should be considered to be *primary* data.
For example, if you went through many TV guides from old newspapers
(secondary data) and counted up the number of Australian comedies that were
shown over several years in order to create a graph of it, this new
information generated by you should be considered *primary* data.
I'm open for a five minute argument
<http://www.montypython.net/scripts/argument.php> on this.
Meet me in room 12A. Warning - *don't* go to room 12 by mistake !
