<div>Your analysis of past papers (and for me the insights gained from being an exam marker for years and vce teacher for 17 years and exam writer etc) would lead you to consider the purpose of the exam and what it means to have a "wasted" question --to set
an exam with a "wasted" question is not worthwhile .... (think about it!!)
<div><br>
</div>
<div>part of teaching unit 3 & 4 is all about understanding the exam and how the exam panel thinks and then acting on that knowledge. </div>

ITA kids are going to be seriously troubled. I'm guessing a question like 3c is going to score about 0.01 marks out of 2 on average across the state. I wonder what the success rate would be amongst ITA teachers for that question... To get my kids to answer
it well, I'd need to spend at least two periods (more like a week) just on normalisation theory - and frankly, it's not worth it.<br>
<br>
Sorry for being grumpy about this, but this level of complexity really does not suit ITA. I don't mind normalisation being a bit of key knowledge, but how it might be examined seems excessive.<br>
<br>
Woof!<br>
