XI. ComputingWhen I was a kid at school I got into programming in Basic. It was mathematical in ways that maths lessons weren't. For instance, the only time I ever asked a teacher how to do something that hadn't been taught was when I needed a bit of maths for a program I was writing.
"How do I stop this weather data looking so spiky?"When I did my teacher training at the Roehampton Institute back in the early 80s, computing was as you know in its early days, not quite as early as when I was at school (there was a screen for instance!) but early days:
"You need a moving average."
But there was a book I really enjoyed, and found captivating, Seymour Papert's Mindstorms. The idea of using Logo in the classroom to program a turtle was a really inspiring one, where you really needed to get to get to grips with maths to get a lot of things done. This short video from the time gives you some idea of what was starting:
Over the years, I've used Logo a lot. You know the kind of thing: forward 10 right 90...
I used the Microworlds environment quite a bit. Now I use Scratch. It can have too many knobs on, too many attractive features, and I think the simple maths of Logo is the best; it continues to be a great way of really needing a lot of maths to achieve an end. I never seem to get quite far enough with it to get on to the wealth of exciting possibilities, but I think this might be changing with the new emphasis on coding in the computing curriculum. I'm using code.org's great resources and courses with my kids, and encouraging the whole school to develop this kind of coding, and although the finely-grained steps of the courses are mainly convergent, I think they provide a great preparation for wonderful divergent work.
Here's a great tribute to Papert:

It is another logo-inspired platform, but I find it more in keeping with the original spirit than scratch. Pencilcode can do more than a wandering turtle, but it feels completely comfortable for students to just move the turtle around. I started leading a programming course for elementary school students using pencilcode, knowing that it was a math course in disguise.

Thanks Joshua - I really like the simple clean look of pencilcode.net - must try it out properly!ReplyDelete
