It was a dark and stormy curriculum; the jargon fell in torrents—except at occasional intervals, when it was checked by violent gusts of puffery which swept up the streets (for it is in Australia that our scene lies), rattling along the schooltops, and fiercely agitating the scanty flames of thought that struggled against the darkness.

Yeah, yeah, a mixed metaphor, or something, but it’s really late and we’re really tired. Anyway, the point is that the writing in the Daft Mathematics Curriculum sucks, and the Introduction really sucks. Like Bulwer-Lytton level of sucking. And, of course, embedded in the suckingness, there is the awfulness.

We’ll get back to hammering the Content-Elaborations as soon as possible, since that’s where the rotten meets the road. Someone, however, has to write something about the godawful Introduction. Which is much easier said than done. The damn thing is sixteen pages. Sixteen Bulwer-Lytton pages. By way of comparison, the introduction to the Current Curriculum is three short, to-the-point pages. (Such modification is what David de Carvalho likes to refer to as “refining” and “decluttering”.)

OK, sure, “mathematising” may be a brilliant new concept.* Nonetheless, someone has to be plenty pleased with themselves to believe that their shiny new toy warrants five times the introduction. And, yes, the ACARA writers are indeed pleased; the Introduction is dripping with smug satisfaction, declarations of the wonderfulness of their new scheme. It goes without saying that this continual self-congratulation really assists the overall flow.

Alright, time to hold our noses and dive in. We’ll take it section by section.**

RATIONALE (p 1)

This section is mostly florid motherhooding: “deep learning” and “creative” and so forth. One sentence, however, is worth noting, as it is a portent:

“Throughout schooling, actions such as posing questions, abstracting, recognising patterns, practising skills, modelling, investigating, experimenting, simulating, making and testing conjectures, play an important role in the growth of students’ mathematical knowledge and skills.”

This is explicitly advocating an experimental/”problem-solving” approach to learning mathematics. Yes “Practising skills” and “abstracting” are there (learning facts is not), but they are just two “actions” in a very long list. Moreover, it is simply false to claim that the rest of these “actions” can play more than a trivial role in “the growth of students’ mathematical knowledge and skills”. Unless, that is, ACARA reinterprets “skills” to include the skill of modelling and so forth. Which ACARA can do, but which then also means ACARA is playing a cup and balls trick with their terminology.

FUNDAMENTAL STRUCTURE (pp 2-5)

Each year level of the Draft Curriculum contains

*) Year Level Description–“overview of the learning”

*) Achievement Standards– “expected quality of learning”

*) Content items – “essential knowledge, understanding and skills”

*) Elaborations on each Content item– “suggestions and illustrations”

The content and companion elaborations are organised under six “strands“:

This replaces the current structure of three double strands — Number-Algebra and so forth — and it is self-evidently ridiculous. It ignores and thus weakens the critical connection between number and algebra. It also means that to have “Algebra” in primary school, ACARA simply has to make stuff up; they have to redefine “algebra” to be pattern-hunting or whatnot.

This is then not simply a case of having the same stuff under different labels. Once algebra is separated from number, it discourages semi-algebraic approaches to arithmetic, and to arithmetic problems. It discourages taking natural conceptual steps from arithmetic to algebra, which can be done, and should be done, in primary school.

The numerous strands also makes it easier for ACARA to push the overhyped Statistics and, more generally, ACARA’s real-world fetishism. This comes out most clearly in the splitting of the current double strand of Measurement-Geometry into Measurement and Space.

Why “Space”? Why not Geometry? The description indicates exactly why:

Space develops ways of visualising, representing and working with the location, direction, shape, placement, proximity and transformation of objects at macro, local and micro size in natural and created worlds. It underpins the capacity to construct pictures, diagrams, maps, projections, models and graphic images that enable the manipulation and analysis of shapes and objects through actions and the senses. This includes notions such as continuity, curve, surface, region, boundary, object, dimension, connectedness, symmetry, direction, congruence and similarity in art, design, architecture, planning, transportation, construction and manufacturing, physics, engineering, chemistry, biology and medicine.

Bulwer-Lytton sits up in his grave, and tips his hat.

The point of this, and the clear awfulness of this, is Geometry, the mathematical consideration of abstract objects, has been trivialised to a tiny element of real-world investigation. Space includes a ton of what would currently be thought of as coming under Measurement, effectively airbrushing Geometry out of existence. And, then, what is the Measurement strand? Well, it’s pretty much just measurement, just quantifying, which is a fine, correct use of the word. Except that as a strand of mathematics it’s pretty damn trivial.

STUFF OVERLYING THE SIX STRANDS — CORE CONCEPTS (pp 5-8)

This is the stuff underlying ACARA’s hideous wheel, and it is when things get truly appalling.

The Core Concepts are intended to replace the four “proficiencies” in the Current Curriculum:

*) Understanding, Fluency, Reasoning, and Problem-Solving.(Current Curriculum)

The current proficiencies aren’t that helpful in practice, since at least the first three proficiencies are much more intermingled than is suggested.*** Still, the current proficiencies are fundamentally coherent. No longer …

The three “Core Concepts” are those blue arcs surrounding the six strands:

Even ignoring the garishness of “mathematising”, the entire thing is absurd. What can “mathematising” mean other than to deal with a “mathematical structure” with a “mathematical approach”. How is “mathematising” anything other than the verb form of the noun phrase “mathematical approaches”? Why is “abstraction” a structure, rather than abstracting as an approach? Why is “generalising” an “approach” rather than “generalisation” a structure? How is “thinking and reasoning” a separate approach? Are the other approaches unthinking and unreasoned? What does “manipulating mathematical objects” mean? Do the other approaches not involve manipulation of anything? Why bother asking any questions at all about something so self-evidently meaningless? Where’s our vodka?

In twenty years of investigating educational absurdity, this diagram and its description out-absurds anything else we’ve seen. By a mile.

STUFF OVERLYING MATHEMATICS — GENERAL CAPABILITIES (pp 8-10)

Everything in the (not just mathematics) Curriculum is supposed to promote the General Capabilities:

*) Numeracy, Literacy, Critical and Creative Thinking, Digital Literacy, Ethical Understanding, Personal and Social capability, Intercultural Understanding.(Current and Draft Curriculum)

The Draft makes no mention of the last two general capabilities, which, given what comes next, is a little odd. Of course, whatever their intrinsic worth, the general capabilities can readily be used as an argument for real-world problem-solving and the like. Of course, that is exactly what is done.

Numeracy needs no comment, since it is already perverting everything, to the point where Arithmetic barely exists. Similarly, Digital Literacy is obvious: why think think when you can push a button and watch a movie? As for the others: Literacy is about communicating problems and real-world contexts; Critical and Creative Thinking is press-ganged into serving problem-solving; Ethical Understanding amounts to gathering and analysing data on whatever needs ethicising.

MORE STUFF OVERLYING MATHEMATICS — CROSS-CURRICULUM PRIORITIES (pp 10-11)

Everything in the (not just mathematics) Curriculum is supposed to promote the Cross-Curriculum Priorities:

*) Aboriginal and Torres Strait Islanders, Asia, Sustainability (Current and Draft Curriculum)

The Draft ignores Asia, for God knows what reason. Sustainability is what you’d expect, the “modelling” of this or that. And, predictably, the description of Aboriginal and Torres Strait Islander mathematics is strained, embarrassing and plain silly:

[Aboriginal and Torres Strait Islander Peoples] tend to be systems thinkers who are adept at pattern and algebraic thinking, …

Go on, pull the other one.

For example, within the probability and statistics strands, stochastic reasoning is developed through Aboriginal and Torres Strait Islander instructive games and toys.

Huh. They pulled the other one.

We really wish well-meaning clowns would cease this tendentious nonsense and instead focus on the stopping of aboriginals being beaten up by racist cops.

Just to be clear, the A and TSI description in the Introduction is ridiculous, but it is not half-way as ridiculous, nor a tenth-way as damaging, as ACARA’s Core Concepts nonsense. It’s easy to make fun of this stuff, and it should be made fun of, but it is not even close to the main game.

MATHEMATICS AND OTHER SUBJECTS (pp 11-12)

There is nothing exceptionally notable here. It is just another opportunity taken to push the real-world contexts of mathematics, exactly as was done with the General Capabilities.

MORE STUFF OVERLYING THE SIX STRANDS — KEY CONSIDERATIONS (pp 13-16)

This is the last section, and it is very weird. And very bad. It seems to be attempting to serve the same purpose as the Core Concepts, but with no proper connection to the Core Concepts nor, as far as we can see, to anything else in the Curriculum documentation. It’s as if the Core Concepts section didn’t exist, or someone realise/admitted that the Core Concepts section was meaningless.

in any case the Key Considerations are:

*) Understanding, Fluency, Reasoning, Problem-Solving, Experimentation, Investigation, Mathematical modelling, Computational Thinking, Computation algorithms and the use of digital tools of mathematics.

Note that the first four Key Considerations are exactly the four Proficiencies in the Current Curriculum — what the Core Concepts are meant to be replacing. But, then we have five more Considerations, all shoving us towards modelling, real-world contexts, computers and whatnot. The purpose of this is obvious, and it is bad.

There are minor changes in wording from the first three Proficiencies in the Current Curriculum to the corresponding Considerations. The new wording is generally worse, including an annoying amount of self-promotion, but is basically ok. The problem is with the rest of the Key Considerations.

The Proficiency on Problem-Solving is extensively reworded in the corresponding Consideration, with explicit linking to the next four (new) Considerations. Embedded in it is ACARA’s definition of Problem-Solving:

Students formulate and solve problems when they: apply mathematics to model and represent meaningful or unfamiliar situations; design investigations and plan their approaches; choose and apply their existing strategies to seek solutions; reflect upon and evaluate approaches; and verify that their answers are reasonable.

The last five Considerations are predictable and need no comment, except for Computational Thinking. This is described as follows:

The Australian Curriculum: Mathematics aims to develop students’ computational thinking through the application of its various components, including decomposition, abstraction, pattern recognition, modelling and simulation, algorithms and evaluation.

Framed as such, Computational Thinking is no different from standard aspects of Mathematical Thinking, except for the inclusion of “modelling and simulation” — which is jammed in even thought it doesn’t remotely fit — and “algorithms and evaluation”.

The point is then given away in the next line:

Computational thinking provides the strategic basis that underpins the central role of computation and algorithms in mathematics and their application to inquiry, modelling and problem solving in mathematics and other fields.

“The central role of computation and algorithms in mathematics”.

Clearly, the point is not to promote Computational Thinking. The point is to promote computing.

There is a strong push for this type of content, usually under the title “Algorithmic Thinking”. It can, rarely, refer to nice investigations of algorithms for solving mathematical problems. In this form, and only in this form, Algorithmic Thinking has a natural and minor place in a mathematics curriculum.

But that is not what is going on here. What is going on here is the turning of mathematics into an experimental subject and a computer science subject, in order to write crappy little programs to run on crappy little models. It is not a mathematics education and it is not remotely good.

We’re done. Thank Christ.

****************************************

*) It’s not.

**) It’s a minor complaint in the scheme of things, but it is worth noting that the section labels and subsection labels have almost indistinguishable fonts, making it almost impossible to keep track of where one is. How a bunch of guys who cornered the market on Neon could even stuff this up, God only knows.

***) The fourth proficiency as well, if one has a Singaporean view of “problem-solving”

This is another quick one, but it keeps the bullets flying while we prepare a more substantial post for tomorrow(ish). It can be considered a companion to the previous ACARA Crash a Content-Elaborations for Year 8 Number.

CONTENT

recognise and investigate irrational numbers in applied contexts including certain square roots and π

ELABORATIONS

recognising that the real number system includes irrational numbers which can be approximately located on the real number line, for example, the value of π lies somewhere between 3.141 and 3.142 such that 3.141 < π < 3.142

using digital tools to explore contexts or situations that use irrational numbers such as finding length of hypotenuse in right angle triangle with sides of 1 m or 2 m and 1 m or given area of a square find the length of side where the result is irrational or the ratio between paper sizes A0, A1, A2, A3, A4

investigate the Golden ratio as applied to art, flowers (seeds) and architecture

We’re still desperately trying to find the time to properly go through the Daft Curriculum, and we hope to have some longer posts in the coming week. Until then we’ll try to keep things ticking over, sniping a little each day.

This is a short one, and can be thought of as a WitCH or a PoSWW. It is a Content-Elaboration for Year 6 Algebra. We won’t comment now, except to note that we cannot see how any competent and attentive mathematician (or grammaticist) would sign off on this. The consideration of possible corollaries is left for the reader.

CONTENT

recognise and distinguish between patterns growing additively and multiplicatively and connect patterns in one context to a pattern of the same form in another context

ELABORATION

investigating patterns on-Country/Place and describing their sequence using a rule to continue the sequence such as Fibonacci patterns in shells and in flowers.

Let’s start at the very beginning A very good place to start When you read you begin with A B C When you count you begin with 1 2 3, establishing an understanding of the language and processes, and which you use to quantify, compare, order and make correspondences between collections.

It’s just possible that Julie Andrews will single-handedly take down ACARA.

We’re desperately trying to find the time to give the Daft Australian Curriculum the comprehensive hammering it deserves. Until we can get to that, we’ll keep things rolling with a series of short(ish) posts: ACARA Crash (pronounced with a thick Italian accent). We’ll start at the very beginning … with Foundation, the Prep year or whatever you want to call it.

What’s the very first thing you want to teach (or confirm the knowledge of)? Yep, you want the kids to know the numbers, their symbols and their names, and you want them to be able to count. You want the kids to have a sense of ordering, and the language to capture it.

It’s pretty straight-forward, and fun. Sing some counting songs, practise writing the words and the numerals, watch out for those reversed 5s. Maybe go to an antique shop and grab some coloured blocks to play with. There are things to be learned, practice to be done, the understanding of ordering to be gained. But there’s just not a whole lot need be said about this practice. ACARA, of course, believes otherwise.

Following on from its (bloated) content on number names and its (badly misplaced and bloated) content on quantifying, ACARA has their content descriptor on counting:

“establish understanding of the language and processes of counting to quantify, compare, order and make correspondences between collections, initially to 20, and explain reasoning (AC9MFN03)”

There is a fundamental rule of teaching: say less. Make every word count, and if nothing needs to be said then say nothing. It is a rule that ACARA (and all education princelings) desperately needs to learn.

What is the point of ACARA’s word swamp? In what conceivable sense can it be considered “refining” or “decluttering”? What does it clarify to anyone? How is it in any way better than a bare bones content description:

Teach the little monsters to count.

Ok, you might want to tweak the wording, but for content, that is pretty much it. None of ACARA’s blather is required or remotely helpful. It is much, much worse than the corresponding content in the current Australian Curriculum.

Content is meant to be the bones, the clear and solid structure. If you want meat then sure, have meat. But if you don’t want to lose sight of the bones — and you really, really don’t — then put the meat in the damn meat section, in the elaborations. And of course, ACARA has plenty more meat in the elaborations; it will come as no surprise that their meat is off.

Most of ACARA’s counting elaborations are benign, just standard classroom exercises and token (but ok) Aboriginal material. Ten elaborations is more a textbook chapter than elaboration, but individually they’re not intrinsically bad. The problem is with what there isn’t, and it is a massive problem.

After counting, what sense of number do you want Foundation kids to attain? The answer is in the question: you want them to begin to develop a sense of number. Beyond the Four Horsemen and the Third Man, you want the kids to develop a sense of fourness and threeness, numbers as quantity, and the prelude to proper arithmetic. That is abstract and not easy, which is why it is important to begin with the hints early on.

The current Australian Curriculum, is not strong on this, but the draft curriculum is way, way worse. The stage is set right at the start, by ACARA’s “Level description” for Foundation mathematics:

The Australian Curriculum: Mathematics focuses on the development of deep knowledge and conceptual understanding of mathematical structures and fluency with procedures. Students learn through the approaches for working mathematically, including modelling, investigation, experimentation and problem solving, all underpinned by the different forms of mathematical reasoning. As students engage in learning mathematics in Foundation year, they:

explore situations, sparking curiosity to investigate and solve everyday problems using physical and virtual materials to model, sort, quantify and compare

begin to bring some mathematical meaning to their use of familiar terms and language when they pose and respond to questions and explain their

look for and make connections between number names, numerals and quantities and through active learning experiences, compare quantities and shapes, using elementary mathematical reasoning

build confidence and autonomy in being able to make and justify mathematical decisions based on quantification and direct comparisons

learn to recognise repetition and apply this to creatively build repeating patterns in a wide range of contexts

begin to build a sense of chance and variability when they engage in play-based activities, imagine and think about familiar chance events.

For Foundation year? “Deep knowledge and conceptual understanding”? Have you gotten them to count backwards yet? Have you bothered to try to explain what a number is?

This is nonsense, of course, but it is also poison. Pretty much all of the Number strand in the Foundation Year is on “modelling” and “Problems” and “practical situations”, and there’s a lot of it. There’s barely a hint of numbers as numbers, and what hint there is, is certain to be dissolved and forgotten in the ocean of inquiry.

Sure, you expect young kids to be playing with things more than ideas. They will add three blocks to four blocks many times before they add 3 + 4. But there are better and worse activities to suggest and encourage this abstraction; ACARA’s are much worse, and deliberately so. The writers don’t want it. Fundamentally, they don’t want mathematics.

What the draft curriculum makes clear, already at the Foundation level, is that the curriculum writers, deep in their hearts, hate mathematics. They hate the abstraction at the heart of mathematics and proper mathematical thought. They might love what mathematics can do, assigning numbers here and there, but their sense of mathematics is wade-pool deep. Real mathematics, they hate.

This hatred glows brightly from almost every line. Almost never is the opportunity grasped to display the internal beauty and power of mathematics. Almost never is mathematics promoted as its own end, as its own good. It is clearly unimaginable to the writers. Mathematics is just a tool, the annoying but necessary “m” in STEm.

This is not just cultural philistinism, it is ACARA shooting its own philistine feet. Without a proper appreciation of mathematics and the source of its power, all of ACARA’s real-world games are, well, just games. 13 years of pointless games, that’s what’s on offer.

There is plenty more nonsense in Foundation draft: we haven’t even mentioned the “Algebra”. But that’ll do. We’ve never paid much attention to the Foundation curriculum. We figured the damage mostly began around Year 2, and up until now that is probably true. But no more: ACARA’s draft begins with a perfectly awful Foundation for the greater awfulness to come.

Send me a postcard, drop me a line Stating point of view Indicate precisely what you mean to say Yours sincerely, wasting away

Give me your answer, fill in a form Mine for evermore Will you still need me, will you still heed me I’m nineteen sixty-four

Below is a document from a foreign country, one of yesterday’s finds. We have our thoughts, and we shall update the post pretty soon. First, however, we’ll give people a chance to ponder. Think of it as a WinCH.

UPDATE (09/05/21)

Courtesy of the Evil Mathologre, the PDF below now has (somewhat clunky) OCR. That means you can search for words, such as “mathematising”.

We went to a strange jungle-bookshop yesterday, hunting for copies of the mythical Fitzpatrick and Galbraith. No such luck, but we did find plenty of fascinating and forgotten items. And, below is the lovely shop assistant Jill, totalling our many purchases.

Of course we rebuked Jill for not doing the sum in her head.

We’ll write about some of these very interesting finds in the near future.

We decided ACARA’s psychedelic circle, which we discussed briefly here, was worthy of its own post. So, apart from the potential to trigger an epileptic fit, what is wrong with ACARA’s wheel?

ACARA labels their wheel as depicting

[the] relationship between the six strands and three core concept organisers

The six strands make up the inner wheel, and are explained here (pages 4-5). The three “core concept organisers” are the three colours on the wheel rim, with the categories and subcategories as pictured below, and which are explained here (pages 5-8).

That’s pretty much it, except for the “bemused” bit. But our cheap-joke title is also asking a genuine question: what does ACARA think is the essence of “problem-solving”? How do you solve a problem like ACARA (does)?

However, Mr de Carvalho said problem solving was at the core of the curriculum in Singapore, whose students consistently topped the global education rankings, …

There is plenty more, similar bait in ACARA’s comparative study of Australia and Singapore (discussed here and here). So, let’s take a closer look at the bait, at the problem-solving “core” of Singapore’s mathematics education.

A “problem” in mathematics can mean many different things. In particular, a problem can be absolutely routine, what would normally be referred to as an “exercise”, and is there for the practice of basic skills. But not all exercises are routine. An exercise may require more care in setting up, or involve nastier numbers entailing trickier computation, or more subtle manipulations of the equation(s). It is still an “exercise”, in the sense that it is there primarily there to test and to practise specifically chosen skills, but it can be a hard exercise. It may stretch the student, but within clearly defined parameters, with the required facts and skills clearly understood.

At some point such hard exercises would more naturally be called “problems”. If they’re sufficiently difficult you might call them “hard problems”. But none of that changes the essential nature of these exercises/problems, that they’re there for the testing and practicing of clearly defined facts and skills. And, in that way, these problems presume some prior mastery of those facts and skills. The harder the problem, the greater the mastery presumed.

This is the way to understand “problem-solving” in Singapore’s mathematics education. We have more to learn, but everything we have found so far points to exactly what one would expect: in Singapore, “problem-solving” largely amounts to the serious practicing of hard, up to very hard, exercises, based upon a prior mastery of fundamental facts and skills.

It is easy to get a sense of this simply by searching for “Singapore test papers”. This is one such site, and this is a Primary 6 test paper from that site. Not all the questions are hard, but they get plenty hard. Some of that difficulty is in the material being more advanced — Primary 6 students do a decent amount on rate and ratio problems, including some algebra — but that’s not the only reason. There is plenty harder, and the reader is encouraged to hunt, but here is a quick, telling example from the Primary 6 paper:

Which of the following fractions is nearest to 2/3?

1) 3/4 2) 5/6 3) 7/9 4) 1/3

That’s a Singapore maths problem. Just a fraction comparison question, but a hard fraction comparison question. You can’t possibly do the question quickly without being light on your fraction toes.

That’s the bait, Singapore’s problem-solving. And now, the switch: what does ACARA mean by problem-solving?

It is abundantly clear that ACARA’s notion of a “problem” is not remotely like Singapore’s focussed and difficult exercises. ACARA’s “problem-solving” is of a much more open-ended and exploratory nature. It is inquiry-based learning, with the little kids being intrepid little Lewises and Clarks. This is immediately clear from De Carvalho’s conscious decision to highlight a ridiculous “why”-hunting exercise, with the kids supposedly discovering Pythagoras for themselves.

It is also abundantly clear from ACARA’s documentation. Front and centre in the draft mathematics curriculum is the diagram below. It is one of the silliest, over-egged pieces of nonsense we’ve ever seen:

This craps smells very much of CCR. Whatever its origin, notice that at the bottom of the pretty blue list of “Mathematical approaches” is “problem-solving and inquiry”. This is then explained:

Problem-solving and inquiry – skills and processes that require thinking and working mathematically to understand the situation, plan, choose an approach, formulate, apply the relevant mathematics, selecting appropriate and efficient computation strategies, consider results and communicate findings and reasoning; Problem-solving and inquiry approaches that involve thinking and working mathematically include experimenting, investigating, modelling and computational thinking.

Ugh! But let’s go on.

ACARA is explicitly linking “problem-solving” to inquiry based learning, but it is worse than that. This problem-solving is more than an approach to the curriculum, it is the curriculum. From ACARA’s What Has Changed and Why:

The content descriptions and the achievement standards in the consultation version now explicitly include the critical processes of mathematical reasoning and problem-solving from the proficiency strands. This results in a mathematics curriculum that supports deeper conceptual understanding to make mathematical learning more meaningful, applicable and transferable to students. [emphasis added]

That is, “problem-solving”, meaning inquiry-based learning, is now to be part of the content of the Australian Curriculum. De Carvalho can claim that “ACARA is not making any recommendations about pedagogical approaches”, but his claim is clearly, ridiculously false. And here is the falsehood in the flesh. Here is just one of a zillion such content descriptions, this one from Year 2 Number:

model situations (including money transactions) and solve problems involving multiplication and division, representing the situation as repeated addition, equal groups and arrays. Use a range of efficient strategies to find a solution. Explain the results in terms of the situation

This is garbage and, with absolute certainty, it is not Singapore.

What is Singapore doing while Australia is playing these idiot inquiry games? The students are learning their damn multiplication tables, so they can go on and do Singapore problems. Problems worth doing. Problems that the vast majority of Australian students haven’t a hope of being able to do.

It is a blatant and insidious lie to claim that ACARA’s problem-solving push in mathematics is even remotely like Singapore. And it is a hugely damaging lie. Inquiry-based learning is a disaster; it is already here in Australia and it is already disastrous. As we have written elsewhere, the poor kids aren’t Lewis and Clark; they’re Burke and Wills. They don’t have a chance in hell of getting anything solid, of retaining anything from these aimless treks.

Does one need a proof that inquiry-based learning is a disaster? No. It is obvious on its face, to anyone with any decent understanding of what mathematics is and how children learn. But, for anyone who needs a proof that dumb is dumb, Greg Ashman has written an excellent post on ACARA’s Singapore nonsense and the evidence for the failure of inquiry-based learning.

ACARA are bait-and-switch swindlers and swill merchants, and they should be disbanded. That’s how to solve a problem like ACARA.
