Transforming our thoughts about teaching

Posted in Computing, Education, Mathematics, Science, Video on December 12th, 2007

This wonderful little video (produced by some U of M Twin Cities mathematicians) has apparently been viewed over 1 million times now, which is a lot more views than it would ever get in class. I frequently run into faculty that are very intent on holding on to their teaching ideas and techniques, and certainly not sharing them openly with the world. They see those ideas as “their property”, to be guarded and controlled as much as possible. It’s a weird attitude, because almost none of them will ever see any money from those ideas, and the potential for wider viewing and usage is just so much greater if they open up (as in this case).

A good video like this takes a lot of time to produce, but faculty often put in huge hours on their lectures, labs, and demonstrations. Get it out there!

Making software simpler instead of more complex

Posted in Computing, Education on November 29th, 2007

Those crazy kids at KOffice have created a simplified version of their office suite especially geared for kids. A cool feature, though, is that it’s fully interoperable with the “adult” version of the suite, so teachers/parents can open documents created by students/kids and vice versa. Nice.

open… has some nice thoughts on the role of open source in a process like this:

These are precisely the kind of innovations that free software makes so easy: hacking together a quick prototype and then polishing it. Let’s hope that other simplified versions follow, since an “Easy” Office would be useful far beyond its original target market, education.

It would also be a nice riposte to never-ending complexification of Microsoft’s own products, which are forced to add more and more obscure features - whether or not users what them - in a desperate attempt to justify yet another paid-for upgrade. Free software is under no such pressure, and can therefore downgrade applications when that might appropriate, as here. Microsoft, by contrast, is trapped by its ratchet-based business model.

Show me what they really want (and don’t assume it’s the money)

Posted in Computing, Music, My writing, Research, Science, Writing on November 24th, 2007

Langdon and Poli
There’s been much written and said about Radiohead’s decision to let punters name their price when downloading their new In rainbows album. While some of this heat and noise as been quite sensible, much has been predictable tripe about how stupid and naive the band has been. There is some evidence, however, that the band wasn’t so daft, and that their monetary take may have indeed been not to far from what they (as the band) would have seen through traditional marketing channels.

More importantly, though, I think most of this blather totally fails to grasp the more central question: Most bands (artists, writers, open source programmers, etc., etc.) aren’t in it for the money. If you take out the handful that make a fortune (can we please take out the reformed Spice Girls? please?), most people who do this sort of thing aren’t looking to get rich, and many don’t even expect to pay the bills (hence the term “day job”). For them, the value is often much more in being heard (or read or whatever).

As a concrete example, Bill Langdon, Riccardo Poli, and I are considering expanding a chapter we’ve (in fairness, mostly they’ve) written on genetic programming into a full on book. The traditional model would be to find a (science) publisher (which we could easily do), and then have them produce and market the thing. It would sell a few copies, and we’d make a few bucks along the way. That kind of book is never gonna sell 10M copies, however, and we know going in that we’ll never make very much monetarily. But that’s not why most academics write papers and books; if it was we’d be the daftest lot on the planet. (No, don’t go there…)

What we’re after is, in a crude sense, references. Since we’re not going to get rich, we’ll settle for famous (at least in our circles). So we want as many people to read, use, and reference our book as possible, for that’s really the currency of the realm where we live. (And, in truth, that currency converts back to hard cash in complex and indirect ways, through pay raises, increased odds on grant applications, invitations to give talks and tutorials, etc., etc.)

So our intention is to follow a model not so far removed from Radiohead’s (although we’ll probably not get nearly as much press). Our tentative plan is to self-publish using one of the many print-on-demand sites, so there will be a printed, bound copy people can buy; we’ll keep the price low, because we’re more interested in volume than immediate profit. We’ll also give the book away, probably in HTML and PDF formats, to encourage people to check it out, use it, and refer to it, regardless of whether they ever actually buy a copy. We might have a PayPal donation button, sort of like Radiohead’s download for free and pay us what you think makes sense. Or we might not; that’s a bridge we’ll cross when we get there. We’ll do most of the marketing, taking copies to conferences, getting it mentioned on the relevant web sites and discussion groups, and hopefully picking up a fair bit of word of mouth along the way.

I don’t expect we’ll ever see much money on this deal, but I’m quite optimistic that the three of us can put together a book that’ll get used, and that’s the point for us. Similarly, Radiohead’s made enough money on their music that I doubt they’re deeply concerned about a few dollars here or there. They want to be heard and talked about, and they are. Hopefully we can have a somewhat similar experience.

I should also be clear that just because people like Radiohead (or struggling new bands) choose to give away their music, we shouldn’t just write them off as fools and rip them off at every opportunity. We all benefit from their passion, and it’s in our collective interest to support that when we can. That’s part of why I do my darndest to avoid giving money to bands that are already making a ton - they don’t need my support. I prefer instead to spend my money on the zillions of cool, but virtually anonymous, acts that can really benefit from a few bucks.
