This is our post for noting local nonsense in the new Australian Mathematics Curriculum (downloads here). It is a list of the content descriptions and the elaborations that appear to be deficient/wrong/misplaced/weird/whatever. It includes anything that has come to our attention and has sufficiently annoyed us and/or others. (This post supersedes a previous post, and the suggestions already made have been incorporated below.) There is no intention to be comprehensive, which would probably entail transcribing 80% of the thing. We’ll just keep adding over time, as awfulnesses come to our attention. Of course criticisms and suggestions and discussion are always welcome, and can be made in the comments.

Note that this post is for the identification of local awfulnesses only. Capturing the global, systemic awfulness of the Curriculum, including the many appalling delays and omissions, would require a massive effort, which we have no intention of doing again, and which is also not required: most of the posts listed here still apply in large part, and often in full. The Curriculum excerpts are also not accompanied by any discussion of the awfulness; we’ll update with links to comments and other sources as seems worthwhile.

The (ostensibly mandatory) content descriptions are flush, and the (ostensibly optional) elaborations are indented. The content description linked to a given elaboration is only included if the content is there on its own demerit.

These examples are suitably horrible to compel one shun the light and become a hermit but I have to wonder what the point of all of this is?

I have seen time and again the forces of “curriculum reform” and in particular mathematics education reformers beaten back, only to return once again with a vengeance. They wait until the people naysaying (their pet projects) are gone and then they come back with promises of improved performance. You really have to be impressed with their persistence and their ability to take advantage of opportunities ( a new minister of education or a new state head of a board of studies). And time and again their edu-fads and teacher training reforms fail with each TIMMS or PISA ( yes Marty I know your take on PISA but people use it as a metric nonetheless) report. And what do they tell their masters when the dismal results come? That we need to go further down the path of reform! And if I see another bogus response quoting the wonders of Finland again I’ll do an injury to someone.

But once again I ask, what is the point of all of this? Is it to improve education? I find that hard to believe given the entropic decay that we have witnessed at all levels. Is it gender equality? I was at an education conference that I actually heard a talk in which a speaker proudly proclaimed that at VCE level girls now outperformed boys across all subjects except physics and specialist maths . The fact that this indicates a looming catastrophe with half of the student population educationally underperforming was lost on this ideologue as she queried why physics and specialist maths were such misogynist holdouts (physics has been denuded of any difficult material i.e. advanced maths since).

Or is it equity that the educrats seek? I recall your recent republishing of Tony Guttman’s letter in which he declared that to him it was irrelevant where someone came from, but it was of prime importance that equality of opportunity be given and that ability be recognised and fostered.

Equity might come on several forms.

1. It can come from identifying talent and fostering interest with resources being allocated where they are needed. But this is a high energy path with well trained and resourced teachers; materials that are correct and yet engaging; assessments that actually have meaning (not testing every damn thing every week for the sake of it). It takes a hell of a lot of money, commitment and energy to run this.

2. The more depressing from of equity is what we appear to be aiming at-as amply demonstrated by ACARA here. Uniform mediocrity that disables differentiation between those who can and those who cannot. It is a lower energy system in that it is easiest to deny opportunity of high performance. Who hasn’t heard “the smart ones will be OK because they can look after themselves”? By lowering what is expected in order to achieve an agreed educational standard the universities and employers won’t know what a person is able to achieve….a perfect utopia of equity

And the worst thing: it’s a spiral downwards

I hadn’t noticed the spiral.

The reports from TIMMS and PISA paint quite different pictures.

They both indicate that Australia sucks, one accurately.

It’s … err … awful, isn’t it? One hardly knows where to start, as almost every sentence or statement has some hideousness in it. I might just pick out one – not quite at random – “using spreadsheets” in Year 6 Number. This is a WTF moment. Now I am a technophile: I love technology, I love using it, and I love teaching with it (at university). I love playing with it and fiddling, and wondering what might happen if I change something. But – I have the advantage of a solid mathematics education behind me: 12 years of school (we all went from Prep to Grade 2 at my school); four years of tertiary mathematics, two research degrees. I believe that in all that time the most technology I used was a set of Cuisenaire rods in Grade 2.

Spreadsheets? Grade 6? And to list numbers with up to three factors? I’m just gobsmacked. At that level students will be just using the spreadsheet as a sort of electronic table to enter their numbers in. Irrespective of whether the task is or is not useful in any way (I’m leaning towards the latter), adding technology purely for its own sake has a negative pedagogical value. Time which could be spent actually, you know, doing mathematics, firming up basic arithmetic skills, is wasted in a meaningless add-on.

And this is really just a detail in an ocean of horror. Every comment quoted above by Marty could be equally so attacked. What is clear – and has been so for some time – is that the creators of this thing have no conception of mathematics, what it is, how it can be used, where its power and beauty lie. It’s a race to the bottom, with the idiots in charge.

@Alasdair: In my experience, few students at school know much about spreadsheets.

They also know little about driving a forklift. What’s your point?

Terry and Marty – indeed that was my point. Year 6 students know as much about spreadsheets as they do about forklifts, and both have about the same level of usefulness in a school mathematics classroom.

Also, given some of the spreadsheets I’ve seen in my professional life (and a university is driven by spreadsheets) I think forklift drivers probably do more good, or at least, less harm.

Spreadsheets are important and useful in many areas. Students could learn the basics of these at school, not necessarily in a mathematics classroom.

Terry, I’m happy for you to play Idiots’ Advocate on this blog, and if you want to try to defend the

Year 6elaboration that is being discussed, then do so. But try to stick to the topic.I’ve added a bunch of stuff from Year 6 Number.. Lord spare us, and me in particular.

“using digital tools to systematically explore contexts or situations that use irrational numbers, such as finding the length of the hypotenuse in a right-angled triangle with the other 2 sides having lengths of one metre or 2 metres and one metre; or given the area of a square, finding the length of the side where the result is irrational; or finding ratios involved with the side lengths of paper sizes A0, A1, A2, A3 and A4 (AC9M8N01)”

Don’t see at all how digital tools are relevant here, especially for the “systematic exploration” of Pythagoras’ theorem. I thought it was a joke as a student when we had to do “experimental verification” of Pythagoras’ theorem on tests, but I presume it’ll be even more of a joke if the measurement is done digitally.

I could imagine a conversation going as follows:

Jimmy: Teacher, how does the computer measure the hypotenuse?

Teacher: Jimmy, it uses Pythagoras’ theorem.

Jimmy: How do we know Pythagoras’ theorem is true?

Teacher: Jimmy, well look here, if you measure the hypotenuse using your calculator, you can see its square is the sum of the squares of the other sides!

“using examples such as and to illustrate the necessity that for any non-zero natural number (AC9M8N02)”

I don’t see how this illustrates “necessity” in any way. Proof by example is not an example of proof.

You could also just as well define a^b such that a^0 = 7, or whatever, changing the other rules as you see fit. I wonder what a teacher following the curriculum would say to that.

Thanks, Anon. I’ve fixed up the LaTex in your comment.

This one is interesting (as in I’m genuinely interested in whether or not any school will bother with this because I cannot make much sense of it from an “actually teaching this crap” perspective)

“comparing and ordering fractions by placing cards on a string line across the room”

Who thinks of these things? Another supreme WTF moment. Imaging a teacher teaching fractions by not using a string across the room – could the school then be sued because of improper teaching? But really, this is absurdity of a high order. Where are Spike Milligan, John Cleese, when you need them?

Teacher: “So, children, I’m going to compare fractions 5/8 and 1/2 by marking them on these cards, and putting the cards on this string with the other cards.”

Marko: “Why are you using a string?”

Teacher: “So I can show you how to compare fractions.”

Julie: “Why are you putting the cards there?”

Teacher: “Because – RILEY: STOP PULLING THE STRING, YOU MADE ALL THE CARDS MOVE!”

Benji: “Does it matter?”

Teacher “Of course it matters! … now I’ve got to put them all back in place again.”

Riley: “I don’t understand any of this. Can I go to the toilet?”

Teacher: “No! You went half an hour ago.”

Riley: “But I need to go AGAIN!” [Pulls string]

Teacher (defeated): “OK, go.”

Very funny!

To be fair, that is an elaboration and so it is optional (just like least common multiples and highest common factors). But I agree: who the hell thinks up these ridiculous options? Who proofreads them and says “Yep, that works”?

Such an embarrassment of riches for the critic! But here’s one: “investigating the golden ratio in art and design”.

This shows that the creators of this document are non-mathematicians who have been led astray by crack-pottery that has all the shrill nonsense of a conspiracy theory. The fact is that aside from a very few people who have used it deliberately (Le Corbusier did, I believe), it is no more special or particular or wonderful than any other ratio. Most “uses” of the golden ratio are just wishful thinking, or a sort of geometric pareidolia. In other words, crap.
