Well ... I'll join this party. :) I haven't looked at what's already ported to the XO recently, but there is a fair amount of existing open source math education software already at the elementary school (USA) and middle-school (USA) levels. I'd check out FreeDuc http://www.ofset.org/freeduc-cd http://www.ofset.org/articles/29 I believe the major European languages are already covered, although the main project language on the mailing lists is French. Migrating this software from Debian to Fedora ought to be pretty easy. I don't know about Sugar interfaces, however. I played with the calculator briefly. It's actually not all that bad, but XCalc is better and of course open source. A spreadsheet -- well -- I use them, but aside from their ubiquity, I don't really like them for teaching math. I've loaded the more popular open source ones on my Linux systems but I do nearly everything in R. Now if we're going to be teaching accounting, then I'd say you need one. :) As far as new software is concerned, I'd recommend developing it in EToys/Squeak rather than Python. A "baby CAS" ought to be a lot easier in Smalltalk, being a descendant of Lisp, rather than Python, which is essentially an imperative scripting language. But as far as I'm concerned, the industrial strength open source math software -- Axiom, Sage, R, Octave, Maxima, theorem provers, etc. -- should *all* be available on the school servers! Unless the servers are so limited in RAM, processing power and disk space that they can't be used for this sort of thing, there's no reason I can think of why that power shouldn't be available to the teachers and more advanced students. _______________________________________________ Library mailing list [email protected] http://lists.laptop.org/listinfo/library
