[Informatics] 2015 ITA exam - A15

Tue Feb 2 12:01:21 AEDT 2016

Just to re-iterate what John Wilkie put out this morning….

According to the 2011 -2015 study design:

Analysis involves:
• Determining the solution requirements. … What data is needed to produce the information? …  These requirements can be classified as being functional,

Design involves:

• Planning how the solution will function, and the appearance of the resulting information. The solution design typically involves identifying what specific data is required and how the data will be named, structured, validated and manipulated.

Given the question specifically states specific data requirements, I think it’s quite clear that the answer is (and should be A). This can be found in the Problem Solving Methodology section of the prior study on page 17…which should hopefully solve this conundrum.

With regards to finding out how your kids went with each of the exam questions, you can get group information about the exam from your IT/Digital Technologies Domain/Faculty leader or VASS Co-ordinator/VCE Leader. Only a quarter of our (College and State) students got it right.

Hope everyone is tracking well for this year so far.

Hi All,

My 2 cents just coz…

My understanding is that Analysis sees us identify the data that we require for our project. Just a list of stuff.

In the Design, we flesh this out. Data type, field size, input mask would all be (I consider to be) the ‘specific data requirement’. Leading me to select A.

If the question asked for only ‘data requirements’ for attendances – Date, time, absent – I would select Analysis.

Another question with select word emphasis which causes headaches. I’m very curious about what my students picked.

Regards,

John

Data collection happens in Analysis Stage. Designers do not go collecting data.

I would agree that B is the answer. In the design stage you are more concerned with the how to collect the data you have identified in the Analysis stage. Bad examiners, bad!

Question 15

At what stage of the problem-solving methodology would the specific data requirements for recording attendances be identified?

A. design

B. analysis

C. evaluation

D. development

I said B.
The official answer, I've found out, is A.

But the 2015 study design's description of the PSM clearly said:
"Analysis involves: Determining the solution requirements. What information does the solution have to provide? What data is needed to produce the information?"

I'd say that 'determining what data is needed' is the same as 'identifying specific data requirements', wouldn't you?
