I haven't said a word about Mathematica in this thread. That's a red
herring. I have no idea why you're bringing it up.

Kids struggle, work hard, on the programs. I watch them sweat.

Sitting on some high horse, judgemental and aloof, is actually not working
at all.

These kids learning to code are getting ahead in life.

Controlling XY and XYZ positions, maybe getting a ball to bounce, or
getting graphs to plot in SVG... these involve core math skills.

https://flic.kr/p/U46xub (a codepen I'm working on for next week's class,
requires drawing a triangle, knowing about canvas coordinates versus
document coordinates). [1]

The pedagogy behind MIT Scratch impresses me as both serious and well
developed.

I find it somewhat amazing your ethnic bias is against such innovations.
I'm glad that psychology is not prevalent in my circles.

Some XY grids have an origin at the canvas center
(using "art terms" like canvas is embraced), whereas
SVG puts (0,0) in the upper left, more like the DOM
(document object model).

Students learn from many examples that one needs to
get clear on:

A) where's the origin?
B) what's the unit? (or gauge)
C) what's the orientation? (which way is "north" or "up"?)

Likewise, on this same topic, students learn to
control their cursor, turtle, avatar, self using both:

A) relative position ("forward 10")
B) absolute position ("move to -4, 14")
