k|5e|3m|4h|4ck = kindergarten
e = elementary
m = middle
h = high
c = college
i.e. so-called k16, pre-school through college.
Of course this all looks very cryptic, but I'm just aiming at making it more memorable and compact.
I told some friends in South Africa it was:
in our neck of the woods but my wife says that's just not how it's done here. So I guess I'm not really the authority.
Anyway, my expertise is more in a specific subject area I tout as "a hybrid of CS and math," where CS is short for computer science and math is short for mathematics.
When you blend math with Texas Instruments, you get a calculator-intensive curriculum. But in PDX we've been leaning more and more towards GNU, Linux, open source in general.
So the calculators maybe don't have such a bright future here, except maybe as emulators e.g. kids can write 'em using some event-driven GUI framework, like maybe PyGame.
