60-second learning

Tuesday, November 29th, 2011

Here’s a collection of neat 60-second videos from the Open University that explain some fundamental concepts in a humorous but accurate way.

Can a cat be both alive and dead? Can a computer think? How does a tortoise beat Achilles in a race? Voiced by comedian David Mitchell, these fast-paced animations explain six famous thought experiments, from the ancient Greeks to Albert Einstein, that have changed the way we see the world. Subjects as vast as time travel, infinity, quantum mechanics and artificial intelligence, are squeezed into 60-second clips that will tickle your funny bone and blow your mind.

We need math teachers who know more math

Monday, October 3rd, 2011

Margaret Wente’s column in this weekend’s Globe and Mail is particularly trenchant. She goes after the teaching establishment for producing a generation of teachers who don’t know, don’t understand, and can’t teach mathematics. From what I’ve seen of my kids’ progress through high school, I think she’s hit the nail squarely on the head. At least at the high school level, a B.Sc with a math minor should be a requirement to teach mathematics, and I’d consider enforcing that down to perhaps the Grade 5 level.

Across the country, university math professors report that the math skills of students who are studying to become teachers are generally abysmal. Basic skills such as adding fractions or calculating percentages are frequently beyond them. “If you don’t know math, you can’t teach math,” says Anne Stokke, a math professor at the University of Winnipeg who has launched a petition to raise the standards.

In Manitoba, education students often arrive at university with no more than what’s called “consumer math,” which is what you take in high school if you can’t do real math. To qualify as teachers, they need only one university-level math course – not nearly enough to make up for years of neglect. Even teachers who aim to specialize in high-school math only need to take a few basic courses. “As it stands, I don’t think they come out of university with the proper background to teach mathematics to kids either in elementary school or in high school,” Fernando Szechtman, a math professor at the University of Regina, told the CBC.

You might think that the nation’s faculties of education – the institutions that teach the teachers – would be concerned about this problem. After all, their job is to ensure that teachers know their stuff by the time they’re unleashed on the classroom.

But this concept of teacher training is pathetically behind the times. Today’s faculties of education have much loftier goals in mind. According to them, their main job is to sensitize our future teachers to issues of social justice and global inequality.

Take a look at the comments on the article too. They’re quite interesting.

Texas school board rewriting US history

Monday, May 17th, 2010

As if trying to teach creationism as science wasn’t bad enough, now right-wingers in Texas trying to rewrite the school history curriculum.

Several changes include sidelining Thomas Jefferson, who favoured separation of church and state, while introducing a new focus on the “significant contributions” of pro-slavery Confederate leaders during the civil war.

The new curriculum asserts that “the right to keep and bear arms” is an important element of a democratic society. Study of Sir Isaac Newton is dropped in favour of examining scientific advances through military technology.

There is also a suggestion that the anti-communist witch-hunt by Senator Joseph McCarthy in the 1950s may have been justified. The education board has dropped references to the slave trade in favour of calling it the more innocuous “Atlantic triangular trade”, and recasts Israeli-Palestinian conflict as driven by Islamic fundamentalism.

If this goes into effect, you’ll see liberal parents trying to home school their kids instead of the conservative Christians.

13-year-old labelled terrorist for pointing a finger

Wednesday, April 21st, 2010

A 13-year-old has been suspended from school because of a terroristic threat – she pointed her finger like a gun at her teacher. Another one for The Crazy Years file.

Taylor was wearing an NYPD shirt at school. She says in the last moments of math class, she and some friends were pretending to be police officers. “I was shooting the markers at the front of the board,” Taylor Trostle said. “It was just like this and I was like ‘pow pow’ and then she just turned around.”Taylor was sent to the principal’s office and immediately suspended for three days. Her write up says the finger gun was pointed in the teacher’s direction. “That was considered a terroristic threat because the teacher feared for her life,” Kristin Trostle said. [...] Any threat to a teacher falls under a ‘zero tolerance policy.’

“Now she’s got a very serious mark on her record and she’s labeled,” Kristin Trostle said.

Modern Physics: The Theoretical Minimum

Tuesday, September 22nd, 2009

It’s really remarkable what’s getting put on the Internet these days, especially if you’re one of those people who likes to learn on their own. Here’s something that I really wish I had the time to audit. Stanford University has put an entire survey of modern physics course, taught by Leonard Susskind, online. It’s about 120 hours, but if you want to really understand physics, this would be a very good place to start. (Although I suspect that you might want to learn some calculus first – it’s not that hard and it’s actually useful.)

For the past two years, Stanford has been rolling out a series of courses (collectively called Modern Physics: The Theoretical Minimum) that gives you a baseline knowledge for thinking intelligently about modern physics. The sequence, which moves from Isaac Newton, to Albert Einstein’s work on the general and special theories of relativity, to black holes and string theory, comes out of Stanford’s Continuing Studies program (my day job). And the courses are all taught by Leonard Susskind, an important physicist who has engaged in a long running “Black Hole War” with Stephen Hawking. The final course, Statistical Mechanics, has now been posted on YouTube, and you can also find it on iTunes in video. The rest of the courses can be accessed immediately below. Six courses. Roughly 120 hours of content. A comprehensive tour of modern physics. All in video. All free. Beat that.

Oxbridge lectures go to iTunes

Wednesday, October 8th, 2008

Oxford and Cambridge University will be putting many of their lectures up on iTunes Univesity for free download. The BBC News article doesn’t provide a lot of details, but the quality of the lectures should be high.

The material will include historian David Starkey, music from St John’s College choir and physicists who will “strip down science to the basics”.

Oxford University will use its iTunes output to “showcase our research and enable the public to hear from world-leading thinkers on topical issues”.

Among the contributions will be Joseph Stiglitz, former chief economist of the World Bank, discussing the global financial crisis and Craig Venter on genomics.
