Tangent Tutorials

2009/12/10/1156

As an aspiring electronics geek, I am still collecting cool tools and techniques for my projects. While working on a weekend project, I stumbled upon a treasure trove containing meticulous (almost obsessively complete) advice regarding soldering and circuit board design. These videos were the perfect addition to my education, and even though I already had halfway-decent soldering technique, I have definitely improved as a result of the videos. It even inspired me to get some new tools, like a needle-tipped soldering iron and desoldering wick.

So, unless you’ve been formally trained in an EE course, I really recommend the Tangent Tutorials series of videos. Excellent work, Tangent!

The Quick Brown – watching FOX headlines change over time

2009/03/03/1058

The Quick Brown is a Fox News headline tracker that visually displays deltas (additions and edits) in a quick-to-grok manner. It’s actually possible to watch the sensationalizing in slow-motion, which is as sickening as it is fascinating.

For example, the headline “Obama: Tax cut by April 1″ becomes “Obama gearing up for fight.”

The text of the article shifts from:
“President says he’ll fight to change health care, energy and education — even if lobbyists don’t like it”
to
“President says he’ll fight to change health care, energy and education — as GOP objects to budget’s cost.”

It’s almost like the news is being corroded before our eyes, where a perfectly reasonable story about taxes is tailored into a standoffish piece about Obama targeting the party of Fox News.

Annals of Education: Most Likely to Succeed

But Deutschlander sees his role as keeping the gate as wide open as possible: to find ten new financial advisers, he’s willing to interview a thousand people. The equivalent of that approach, in the N.F.L., would be for a team to give up trying to figure out who the “best” college quarterback is, and, instead, try out three or four “good” candidates.

In teaching, the implications are even more profound. They suggest that we shouldn’t be raising standards. We should be lowering them, because there is no point in raising standards if standards don’t track with what we care about. Teaching should be open to anyone with a pulse and a college degree-and teachers should be judged after they have started their jobs, not before. That means that the profession needs to start the equivalent of Ed Deutschlander’s training camp. It needs an apprenticeship system that allows candidates to be rigorously evaluated. Kane and Staiger have calculated that, given the enormous differences between the top and the bottom of the profession, you’d probably have to try out four candidates to find one good teacher. That means tenure can’t be routinely awarded, the way it is now. Currently, the salary structure of the teaching profession is highly rigid, and that would also have to change in a world where we want to rate teachers on their actual performance. An apprentice should get apprentice wages. But if we find eighty-fifth-percentile teachers who can teach a year and a half’s material in one year, we’re going to have to pay them a lot-both because we want them to stay and because the only way to get people to try out for what will suddenly be a high-risk profession is to offer those who survive the winnowing a healthy reward.

Is this solution to teaching’s quarterback problem politically possible? Taxpayers might well balk at the costs of trying out four teachers to find one good one. Teachers’ unions have been resistant to even the slightest move away from the current tenure arrangement. But all the reformers want is for the teaching profession to copy what firms like North Star have been doing for years. Deutschlander interviews a thousand people to find ten advisers. He spends large amounts of money to figure out who has the particular mixture of abilities to do the job. “Between hard and soft costs,” he says, “most firms sink between a hundred thousand dollars and two hundred and fifty thousand dollars on someone in their first three or four years,” and in most cases, of course, that investment comes to naught. But, if you were willing to make that kind of investment and show that kind of patience, you wound up with a truly high-performing financial adviser. “We have a hundred and twenty-five full-time advisers,” Deutschlander says. “Last year, we had seventy-one of them qualify for the Million Dollar Round Table”-the industry’s association of its most successful practitioners. “We’re seventy-one out of a hundred and twenty-five in that élite group.” What does it say about a society that it devotes more care and patience to the selection of those who handle its money than of those who handle its children?

This is a really interesting meditation on the hiring and assessment of teachers, and its conclusion surprised me. Well, I shouldn’t say it’s surprising to find something that is at odds with the “No Child Left Behind” idea, but this suggestion draws parallels to the “real world,” and ends up making a lot of sense.

I’ve had lots of different teachers over the years, and by now, some of my friends have become teachers. I can say that I’ve been really disappointed in a few cases, where it seemed more like a career choice than a passion; in those cases, the individual had invested too many years in the certification to turn back… Of course, I’ve seen the other side of the coin, too…

This seminar will explore persuasion in a wide range of media. Our task will be to evaluate humanity’s ability to maintain agency in the face of the increasingly sophisticated influence techniques used against us.

Does the emergence of interactive media change the balance of power between the masses and their would-be controllers? Or does the Internet merely provide the illusion of independent thinking on yet another tightly controlled media landscape?

More importantly, what is the real relationship between people, media, technology, and power? How can we come to recognize the biases of the media that we use – especially before we have committed our society to their implementation?
