Yesterday, Bach had an op-ed in the official organ of the Liberal Party (paywalled, thank God). Titled We must raise our grades on teacher quality, Bach’s piece was the predictable mix of obvious truth and poisonous nonsense, promoting the testing of “numeracy” and so forth. One line, however, stood out as a beacon of Bachism:
“But, as in any profession, a small number of teachers is not up to the mark.”
“All students were awarded [the] mark for this question.”
Yep, the question is plain stuffed. We think, however, there is more here than the simple wrongness, which is why we’ve made it a WitCH rather than a PoSWW. Happy hunting.
UPDATE (11/05) Steve C’s comment below has inspired an addition:
The third greatest issue with the exam question is that it is wrong: none of the available answers is correct. The second greatest issue is that the wrongness is obvious: if lies in a sector then the natural guess is that will lie in one of three equally spaced sectors of a third the width, so God knows why the alarm bells weren’t ringing. The greatest issue is that VCAA didn’t have the guts or the basic integrity to fess up: not a single word of responsibility or remorse. Assholes.
Those are the elephants stomping through the room but, as commenters as have noted, there is plenty more awfulness in this question:
“Letting” is sloppy, confusing and pointless;
The term “quadrant” is undefined;
The use of “principal” is unnecessary;
“argument” is better thought as the measure of an angle not the angle itself;
Given is a single complex number, “the complete set of values for Arg()” will consist of a single number.
We had plans a week ago (seems like a year ago) for a PoSSW coronavirus post. But, God, there is so much stupid right now. Who could possibly keep up?
Here is a dedicated post for coronavirus-related stupidity. Commenters are welcome to point to and give links to specific idiocies, or simply to vent. We’ll update the post with the hyper-stupids. (So, standard Morrison/Trump/Johnson incompetence doesn’t cut it, but unloading a whole fucking boat of sick people most definitely does.)
PoSWW 2 (26/2) Courtesy of occasional commenter Franz, cardiopraxis.de gives us a graph showing what “uncontrolled exponential spreading of the infection” would look like:
PoSWW 3 (27/2) The Guardian royally fucks up their 96pt bold headline:
A number of prominent public Health Professionals have written an open letter to Australia’s health ministers and (the stunningly appropriately titled) gambling ministers. The letter is written in a predictably calm, professional and diplomatic manner, but we’ll translate: you people who signed off to keep pokies venues open are out of your fucking minds.
This one comes courtesy of Christian, an occasional commenter and professional nitpicker (for which we are very grateful). It is a question from a 2016 Abitur (final year) exam for the German state of Hesse. (We know little of how the Abitur system works, and how this question may fit in. In particular, it is not clear whether the question above is a statewide exam question, or whether it is more localised.)
Christian has translated the question as follows:
A specialty store conducts an ad campaign for a particular smartphone. The daily sales numbers are approximately described by the function g with , where t denotes the time in days counted from the beginning of the campaign, and g(t) is the number of sold smartphones per day. Compute the point in time when the most smartphones (per day) are sold, and determine the approximate number of sold devices on that day.
This PoSWW comes courtesy of our friend Alison. (Alison is the feistiest Christian since Jesus Christ.) The PoSSW was from a worksheet inflicted upon Alison’s Year 8-9 daughter. We don’t know the publisher of the worksheet.
Reflecting on the comments below, it was a mistake to characterise this exercise as a PoSWW; the exercise had a point that we had missed. The point was to reinforce the Magrittesque lunacy inherent in Methods, and the exercise has done so admirably. The fact that the suggested tangents to the pictured graphs are not parallel adds a special Methodsy charm.
