it was- we know his name =]
yep and there is pictures and videos of him.
i've had problems with this as some trial exams say it's not, but i did the VCAA 2005 yesterday and it said that confidentiality is definitely accepted.
VCAA is VCAA. If they say so, then it's what it is.
That said, I'd disagree with the confidentiality being a major problem. I mean, there are many people called Albert, so that's not necessarily an issue (if his name is even Albert). Yeah, the video and pictures may be a problem, but you'd could argue that the experiment required photos to be taken or something...
What I'm trying to get at is that is there's probably better answers to that question out there (if it is a short answer question) than confidentiality. Something like informed consent, or beneficence. The important thing is being able to justify your opinion, rather than just regurgitating answer. This is particularly important in these ethics questions.
