I really like the traffic on edu-sig as I sense the whirl-winds from here. Nice overlook.
True story: this summer I did another Martian Math class, a short fun experience for self selected mid-teens with a penchant for math and things academic, so there by choice, on a bright summer's day, but only for five days, the last one with the guardians/parents coming in and see what's been happening. University of Portland let me use its very best facility, semi-circular desks, up to date PCs, switches to open and close the blinds, a projector, great sound, adapters for external laptops as well as the instructor version... wow, what a great setup! However, here's the thing: I'm working through a nonprofit agency that piggy-packs on willing colleges and university (Oregon Graduate Institute, Portland State, Reed College...) and so has to communicate as aliens, non-campus in some ways. Martian Math needed VPython if I were to run all my prepared demos (which the students could fiddle with). I have my heart set on Vpython, yet the IDLE for it wouldn't work, not at all. No one had tested it. It was added last minute, when I sent around my memo "you remembered about VPython right?" Bottom line: we could import it in a terminal window version of Python, if we added the path to sys.path to a remote subdirectory. A major pain and I spent quite a few minutes (spread out) apologizing for the awkward setup and saying how, if they did this at home, everything would be smoother. Because that's what I hoped, that they'd do this at home. Which brings me to the moral of my story: if your organizational setup is just a little too complicated, then chances are it's just too impractical to get all the pieces in place. You'll spend energy and get some of it working, but the lingering frustrations will remain significant. What you start to approximate is that "ideal home environment" that you hope each student will be cocooning in for real studying. School is just a place to get ideas to then go off with and learn about. It's too distracting and frustrating to really expect to get much studying done, not in a classroom surely. "Just give us stuff to study and let us come to your for help." That's the flipped classroom and perhaps the developing model more generally. We'll give you stuff to chew on at the school, but you're expected to do a lot of studying on your own somewhere else, like in your "dorm" (wherever you go to sleep and relax). That's the college model though, and with younger kids I think the feeling has been it doesn't really work that way. I will end with two responses to that objection: (1) although I've cast this as a generational picture, there's nothing to stop adults from learning more Python / Sage / Mathematics were they to have the time and motivation, and that might happen to a greater degree in this shifting sands picture, i.e. our primary clients for all this content are / will be adults in many situations, and just because one works with kids (say 21 and under) today, doesn't mean one's only contribution is to the kid-ed biz in the long run. (2) The virtual classroom you get at home is not necessarily an entirely solo environment, removed from peer pressure to perform and to do team work. A buzzing coffee shop is a less formal setting, like a student center. The smartphones are coming along quickly but the tablets even faster (still more innovation happening). So we have that moving target to aim for. I have a scientific calculator on my Razr / M. As an adult, I wouldn't be bullied into exchanging it for a TI. We showed a lot of Youtubes with good sound quality. Mandelbrots and Mandelbulbs especially. We got VPython working well enough. Great class. The guardians/parents were impressed. Thank you University of Portland and Saturday Academy.
