[Edu-sig] recruiting for delta-calc / lambda-calc among post-algebra students

Edu-siggers might be interested in a rhetorical move, mainly for PR reasons (recruiting, morale...), to rebrand "differential / integral calculus" (Newton-Leibniz stuff) as also (equivalently) "delta calculus" (picture Greek letter del hyphen calculus). Why? Well for one "calculus" is too generic

[Edu-sig] post Education Summit at Pycon

Greetings from Pycon 2013 in Santa Clara. We enjoyed a day long Education Summit on Pi Day today (3/14) an pun (py vs pi) that did not go unnoticed. The program featured a keynote by Walter Bender, founder of Sugarlabs, followed by an unconference of three consecutive sessions and seven lightning

Re: [Edu-sig] Python testimonial sought...

Hi Andre -- My clearest memory along those lines was it was a "talking head" maybe Jeff Elkner himself in that student-made video about the virtues of Python. You may recall the video: there's an "old hippie" dad, a parody of a student's father. It's a kind of love story, where this girl show t

Re: [Edu-sig] (no subject)

Hi Dan -- You ask a lot of good questions. I don't think it's required that you know Python cold (i.e. really well) before sharing it with your daughter or others. They see you're tackling something and getting better at it bit by bit, like sailing, playing the guitar, and that's inspiring. If

Re: [Edu-sig] Python's keywords and functions convertor into native language for lowering entrance barrier

I think Kython is a wonderful idea, and corresponding trainers in any Unicode language. Ideally there'd be a Kython -> Python translator, even at the source code level, that only swapped in the Python keywords, builtins, special names, Standard Library names. This looks like a "round trip" exerci

Re: [Edu-sig] Python's keywords and functions convertor into native language for lowering entrance barrier

Hi Murat -- I presume you know that Python 3 source code may use any Unicode strings for names, including variables, functions, classes and so on. That leaves 33 keywords in English. >>> import keyword >>> keyword.kwlist You can write a script that simply catalogs synonyms for builtins. >>> ба
