This is the third of our three WitCHes on VCAA’s Specialist Mathematics Exam 1 Sample Questions. Newcomer aps was first to comment on the error, in regard to VCAA’s webinar, where the same question is “solved” (and see the subsequent comments on that post). Once again, it seems worthwhile to encourage a prominent discussion on an unfamiliar topic, and there is more to say than has come up so far.
This is the second of our three WitCHes on VCAA’s Specialist Mathematics Exam 1 Sample Questions. It may not be quite bad enough for a WitCH, but it’s very not good. Our main reason for posting it is because we believe there is more in the question than might meet a teacher’s eye. As with our previous WitCH, this question is on a new topic, and some visible discussion seems worthwhile. Continue reading “Witch 94: What Are the Odds?”
This is the first of three WitCHes on VCAA’s Specialist Mathematics Exam 1 Sample Questions. We spent a solid hour writing a critique of this one, and another half hour removing the bad language. Given the topic is new, however, and will be not so familiar to many teachers, we decided the question required more prominence, and proper discussion. The question was first flagged by commenter Michael, and the sample questions have been discussed generally on this post and this post. Continue reading “Witch 93: Base Balls-Up”
One of the all-time great literary wallops, by one of the all-time great writers, is Mark Twain’s Fenimore Cooper’s Literary Offenses:
Cooper’s art has some defects. In one place in “Deerslayer,” and in the restricted space of two-thirds of a page, Cooper has scored 114 offenses against literary art out of a possible 115. It breaks the record.
There are nineteen rules governing literary art in the domain of romantic fiction — some say twenty-two. In “Deerslayer”, Cooper violated eighteen of them. Continue reading “VCAA’s Lesser Literary Offenses”
We are so, so sick of Specialist Mathematics. But, it’s gotta be done.
One more from the 2022 Specialist Mathematics Exam 2. Belatedly, we’ve decided this one deserves its own post. It’s probably more of a PoSWW. But, for those weirdos who like to think about this stuff, there are probably also aspects to discuss.
(The title is very clever, but you have to think about it.)*
This one is the last part of the last question of 2022 Specialist Mathematics Exam 2 (not online). It sparked a lot of discussion on the exam post, but seems worth its own WitCH. The question is clearly a mess, but what was intended, and how to think about the mess is not so clear, at least to us. (We showed the question to a professor of statistics, whose first reaction was “Ow!” We’ve applied the smelling salts, and we should be in possession of the professor’s second reaction soon.)
For clarification, we are (kinda sorta) told in the question stem that the masses of the empty cans are normally distributed, but we are told nothing else relevant, other than what’s given below.
Go for it (again).
*) Proving that the title is not really that clever.
Honestly, we cannot believe it. We’ve checked it ten times and we still cannot believe. It’s from the 2022 Specialist Mathematics Exam 2 (not online), and nothing beyond the discussion on the exam post needs to be added. But, after last year’s screw up, and anyway, it has to be posted.
And, you’re done (with VCE maths). We hope it went well.
We hope it went well for youse all.
