By The Numbers

This article discusses the latest round of changes in the WNCP Math Curriculum. Somehow, after seeing perhaps half a dozen rounds of this game, the rhetoric of revolutionary change wears a bit thin.

TIMSS 2007 – How are we all doing in math? – squareCircleZ

The part I find most encouraging in Murray Bourne’s discussion of the latest TIMSS 2007 report on mathematics performance around the world is the distribution of gender differences – in particular the fact that the relative performance of females is stronger most especially in a number of Islamic countries. My top-of-the-head explanation for this is that perhaps mathematics is seen as relatively value-free (and perhaps more artistic than useful) and so is something that females can study without attracting adverse attention, and also perhaps that religious education is seen as more of a male prerogative. If so, then perhaps that portends a wonderful change of culture over the next generation as those with the greater power of reason will eventually find a way to take more control of their society.

Internet Safer Than Thought vs Flickr Perversion

In contrast to this study (which I came to via Stephen Downes)showing that the internet just isn’t the danger to children it is often portrayed to be, we have Alec Couros reporting on Open Thinking & Digital Pedagogy » Blog Archive » Flickr Perversion, which is about the unpleasant experience of finding some of his family photos identified as ‘favourites’ by a couple of apparent perverts.

Philosophy Talk: The Blog: William James and the Squirrel Example.

Philosophy Talk: The Blog: William James and the Squirrel Example.
Yes, James does seem to be confounding a number of issues in that lecture
His resolution of the squirrel dispute (“Which party is right,” I said, “depends on what you practically mean by ‘going round’ the squirrel”) looks more like linguistic analysis than anything else, and his description of of the ‘pragmatic’ principle in the second paragraph as ‘If no practical difference whatever can be traced, then the alternatives mean practically the same thing, and all dispute is idle’ sounds more like a version of positivism.

It is only later in the piece that he identifies pragmatism with the kind of provisionalism that most scientists take towards their theories as being useful pro tem until they need to be refined in order to accommodate further observations ‘less as a solution, then, than as a program for more work, and more particularly as an indication of the ways in which existing realities may be changed’.

How Much is Too Much?

I have always believed that disprportionate reponse is justifiable (if struck once I will strike back unpredictably harder if I can so that there is no future temptation to estimate expected value of an attack). And I understand that in the event of military action some level of “collateral damage” has to be expected (and that even those opposed to a belligerent regime can expect to suffer the consequences of retribution if they have failed to remove it from power). But the scale of suffering now in Gaza (when comared to the ineffectiveness of the attacks which prompted it) does make me wonder how much is too much?

Trigonometry tips @ squareCircleZ

Murray Bourne’s IntMath Newsletter this week includes a nice preamble to the study of Trigonometry. I’d like to be able to link to that item specifically when introducing the topic, so maybe I’ll ask him to isolate it if he has the time.

HERETICAL Dyson on the Edge

Freeman Dyson’s HERETICAL THOUGHTS ABOUT SCIENCE AND SOCIETY as expressed in “the Edge” are a source of some disappointment and frustration to me. Skepticism about a bandwagon is always appropriate, and even more so is it about the various claims for proposed solutions. But to require a rigorous standard of proof in the face of a possible threat that is great enough to merit the precautionary principle and to present spurious “solutions” like adding .01inches of topsoil on every sqare foot of exposed land on earth (when in fact worldwide wherever we live we do many times the reverse of that) are just irresponsible.

Canadians Need Net-Neutrality

Take Action: Say NO to Corporate Control

Open Letter to CRTC Chair Konrad von Finckenstein:

Dear Sir,

Canadians rely on the CRTC, as the federal communications regulator, to act in the public interest, which in this case means ensuring we have an open and neutral Internet.

Due to the limited number of connectivity options, the providers of internet service share an effective monopoly on public access to a global resource (which includes a large amount of publicly funded physical and conceptual infrastructure). This affords those few connectivity providers with the opportunity of hijacking a general public good and diverting its value to their own interests (for example by engaging in media production and sales as well as transmission and then favouring their own content by “throttling” the transmissions of their competitors). Such behaviour is unacceptable and it is your responsibility to ensure that it does not happen.

Corporations like Bell and Rogers must not be allowed to control our access to the Web or degrade the quality of service we receive from our internet service providers.

I therefore submit that the CRTC should order Bell to stop its Internet traffic-shaping practices.

Please protect Canada’s level playing field for free speech and innovation by ordering Bell to cease and desist its “throttling” practices, and be sure to take similar action against any other service provider or other entity which threatens the right of Canadians for equal access to all parts of the internet.

Computer Algebra Systems

(This posting was prompted in part by a brief mention of the issue in  squareCircleZ )

It is often claimed that Computer Algebra Systems will (or already do) eliminate the need for much of what is taught in high school and college math classes but I seriously doubt that that is the case.

Goodbye College Diplomas ?

Stephen Downes links to Tom Haskins saying Goodbye College Diplomas

Thank god that the time will soon arrive when a prospective employer will not be denied the pleasure of reading all my undergrad essays but will instead be able to compare that proof of my learning in detail with those of all of the other 126 applicants for his one available position rather than having to rely on brief summary documents “of a few words and transcript numbers”.

And that in my old age there will be no shortage of doctors qualified to treat my ailments by having met their own self-determined educational outcomes.

Mythical Myths No 7

In “The Myth of the Tragedy of the Commons”, Ian Angus claims that the phenomenon commonly called a “tragedy of the commons” is a myth. But he is wrong. Anyone who is aware of the fate of the Atlantic cod fishery must know the tragedy of an unregulated commons, so the phenomenon is surely real. It is real, and Angus has been blinded by his anger at those who have (ab)used the phenomenon into denying the phenomenon itself rather than the arguments by which it has been (falsely) claimed to justify privatization of public assets.

Online Literacy Is Lesser Than What? – Bauerline earns an ‘F’

OK this is Mark Bauerline again, this time writing in the ChronicleReview.com with a rehash of the ideas he expounded in ‘The Dumbest Generation: How the Digital Age Stupefies Young Americans and Jeopardizes Our Future’ and particular emphasis on the discovery by Nielsen et al in 2006 that “Eyetracking visualizations show that users often read Web pages in an F-shaped pattern”. Now, Nielsen’s discovery is actually not surprising since much if not most web content is designed to be skimmed in search for particular items rather than to be read completely; Nielsen both acknowledges other possibilities with his “often” and doesn’t claim any earth shattering implications other than to make reasonable conclusions about how to design web pages of the kind intended for skimming in such a way that that skimming will be effective. But Bauerlein infers a lot more. Mostly unfounded nonsense. Continue reading

McCain Puts Country Second

John McCain’s nomination of Sarah Palin as his vice-presidential running mate is a mind-blowingly cynical choice in the light of his criticism of Barak Obama as not yet ready to assume the highest office.

Attention Returns to Distraction

A couple of weeks ago I posted briefly on (one of the many responses to) Nicholas Carr’s article in the current Atlantic Monthly.

Now I am reading another article on the topic. Bryan Appleyard in the Sunday Times refers to various recent books and articles about why the “Google generation isn’t as smart as it thinks”. One of his referents is Carr’s article and he refers also to a book by Mark Bauerlein with a similar thesis, but his main emphasis is more on the problems of distraction identified by David Meyer and Maggie Jackson rather than the habits of mind.

There are actually two main concerns being expressed. Continue reading
