Follow the (no) money
The cynic in me says each of the STATE ministers has got an estimate from their Treasury how much this change would cost and has been told in uncertain terms the cash isn't there, don't sign up for anything !
Think
at least 1 days inservice for several thousand primary teachers (each casual costs @ $300 per day)
at least 1 day each inservice for either year 7/8 core teachers or Design & Technology teachers
ensuring every school has enough computers (I have the only lab in the school with what is regarded as a class set (30))
network costs for aforementioned computers + a trained TSO in every school (or a coordinator on 1/2 teaching load)
replacing GP classrooms with computer labs (with the best will in the world we cannot take out a classroom to replace it with a lab we are chockers and management actually want to remove a small lab of 10 computers suitable for senior classes so they can put classes of 20 juniors in there)
I understand some states currently do not have ANY mandatory technology in years 7 & 8 (Tassie?)
