[Year 12 IT Apps] 2010 ITA examiners' report

[Russo, Frank R]

Hi Mark
Technically the only problem with the Gant chart is that Task B and A would have begun @ the same time but then there would have been 3 days slack time while A and then C were completed so the answers would still be correct even though the chart has errors.

Yet another awesome question from the Examiners well almost?

>From the 2010 ITA Exam - Question 5B.  I have a belated complaint now that I've seen the examiner's official answer in the assessment report<http://www.vcaa.vic.edu.au/vcaa/vce/studies/infotech/it-applications/assessreports/2010/itapps_assessrep_10.pdf>.

Can someone please point out if I'm wrong, but I think they've badly messed up the answer, and kids will have unfairly lost up to 4 marks.

>From the PERT chart ...

They asked for a corresponding Gantt chart. Their solution was this:

It's obvious in the PERT that tasks A and B are concurrent.  B is not dependent on A!
Yet in their Gantt, they've clearly shown task B as being dependent on A.
Then, they went on to leave out fact that that tasks E and D were also dependent on task B through the dummy task.

I hate to think that my kids lost marks because of these errors by the examiners.
It's too late to re-mark exams, but it really makes me worry that markers can be given such dodgy official answers when grading papers.

Grrrrr!
