[Yr11 Information Technology] yr11it Digest, Vol 129, Issue 3

Thu Dec 10 12:37:07 AEDT 2015

Hi Katherine. The ambiguity and overlap of the terms is a nuisance. Would
it not also be correct or accurate (!) to say that

"
When calculating student attendance it would be

   - *inaccurate* to only count days when students were in the classroom
   since excursions, incursions etc should also be included
   - *incorrect* if someone has erroneously marked the student present, or
   absent"

I really wish VCAA would be more careful avoiding these lexical conundrums
that only serve to confuse rather than elucidate the key knowledge.

Cheers
Mark
