Actually, just to clarify how my school works: we don't "grade" in the
traditional sense of letter grades.

Rather, a student turns in work and is then coached / coaxed / referred to
readings etc. if the work does not meet all the criteria or even if it
presents a perfect "practice moment" in some way. I.E. each student just
keeps improving the work until in passes. That can take multiple drafts of
any given Python or C# program, or multiple reworkings of a math problem.

In both cases, there's the immediate feedback of an interpreter (e.g.
Python, Mathematica), mixed with the slower feedback of a human, not a
robo-grader.

As a result, if two students sign up the same day for a Calculus course,
one might finish in three weeks, another in ten.

They're not obligated to work at the same rate. There's no "cohort", no
"classmates". It's one-on-one with the mentor, and the feedback is to you
privately, not to you in front of a group.

There's no turning back quizzes with As on some Bs on others, with some
students publicly outed a Cs and below. There's no public shaming, which
is almost a definition of the typical brick and mortar K-16 classroom.

I find this an interesting way of teaching and it's what on-line schools
tend to allow in principle: a private bubble for each student without
"peer pressure" to "keep up" with some cohort. On the other hand, there's
the pressure to have skills and find a niche in the job market. People
come to our school already motivated to learn SQL or JavaScript or whatever.

Is what I teach mathematics? As I mentioned earlier, we have an exercise
where we repurpose the multiplication operator * to serve as a composition
operator, such that two functions might be composed using a Composable
class, a type students are then asked to add to, to make "powering"
possible.

Example:

def f(x): return x + 2
def g(x): return x * 2

c0, c1 = Composable(f), Composable(g)
newc = c0 * c1
result = newc(10) # x 2 then + 2

result should be 22. Then c1 ** 4 (powering), thanks to student work,
would give c1 * c1 * c1 * c1 e.g. (c1 ** 4)(10) = ((((10 * 2) * 2) * 2) *
2) = 160.
