Mine were e.g. in computer graphics related subjects. We had one teacher
that tried to keep ahead of the class by one week, but failed because of
over consumption of C2H5OH. To this day he is also the only person I
have ever met with a technical university degree that did not understand
the equation for a straight line.
The practical part was more fun, but we had a japanese arts student to
help us there...
The exam was a joke too, we could use our book and the questions were
like 'give the definition of...', 'what two problems are there when
using technique X'.
Aside: my main surprise in this was that the students from CS simply
accepted this level of teaching, many did not even notice.

That was something that surprised me as well - but then again, when I
took my Assembly class, I had programmed in something like 15 different
languages - more than anyone else in the class - and had been programming
(even was paid to write code) since I was about 10.
So many CS students need that level of teaching, because they have
(perhaps) math aptitude, but not (a lot of) hands-on experience writing
code.

A low level would be acceptable for that reason. But a guy that writes a
straight line and axes on the blackboard with a formula that does not
match what he has drawn? Adding that there is a problem with either
horizontal or vertical lines, because something might become infinitive
and choosing the wrong one (matching neither his formula, nor his
graph)? Or the assistant at the practical part that does not know the
difference between a variable and a parameter?
Nobody needs that level of teaching.

That's certainly true - what's being taught has to be taught effectively
*and* correctly.

After further consideration, I think you're right, yes. :-)

That would be the "fixed point" part of my comment. Of course, if you want
high precision rationals, you might wind up with multi-word integers, at
which point you might as well just use floating point unless you're back on
8-bit hardware or something.

Cold hearted orb that rules the night,
removes the colors from our sight,
red is gray and yellow white,
and we decide which is right,
and which is a quantitization error.

Making a pot is rather different from the art of pottery making, tho. We
give kids fingerpaints in kindergarden and we don't call it "art class". Or,
at least, we don't think we're teaching them anything about art.

Symmetries help in that they reduce the number of cases you have to code
for. They don't make the math itself any simpler.

Sure. But it /was/ a school for stupid people... I have no idea what
they have in real schools.
Although, my sister's school did a production of Joseph and the
Technicolour Dreamcoat. And it was almost worth paying good money to
see. (!)
