I couldn't agree more! Such interactive programmes are often so
much more valuable than hours of talking (even though doing
interactive programmes all the time will wear the students out -- as
always, there is golden middle here ^_^).
Another idea in that direction is to make two or three groups, and
then have a little competition of who can sort a pile of post-its (or
whatever) fastest. And I would recommend to surprise the students.
Once they have learned how to sort numbers, say, give them post-its
with picture of animals, say, or melodies, or whatever you fancy.
That forces them to think outside of the box, and suddenly computer
science class becomes so much more meaningful and memorable!
Yet another idea: how about sorting Morse code? Usually, we get it
sorted from 'A' to 'Z'. But there are other ways, and before you know
it, you are discussing trees...

Quoting kirby urner <kirby.ur...@gmail.com>:
I'm glad Tobias took the bull by the horns and didn't eschew a
deeper look into the sorting algorithms.
As a big fan of animations, my reflex is to scour Youtube for
graphical renderings of the different strategies, but then another
thought crops up: lets get out of our seats and do choreography,
Math is an Outdoor Sport! (PR poster). I should explain.
The relationships between programming and scripting theater
"programmes" (old spelling) are deep. Give each student a postit
with a number and have them *enact* the sorting algorithm. E.g.
starting in a row, turn to person on your left (if there is one) and
swap places if your postit number is higher... have directors and
make a video. Now choreograph (enact, dance) in a different way.
Symphonies, plays, musicals, are so multi-track, so parallel, and
yet we fail to exploit those intuitions sometimes.
Let the Theater Department handle it, in consultation with CS.
Could go under the heading of "Unplugged". Likely the Hobbits are
already doing this in New Zealand (NZ has pioneered unplugged more
than most, plus has Hobbits).
Seriously, having lived in the Philippines where people routinely
learn group dancing, I'm worried about only acting as teams in three
capacities (a) cheerleader (b) athlete on the field (c) band.
Theater is being eliminated in favor of competitive sports. Perhaps
CS could come to the rescue and say "wait, we need Theater for our
simulations".
More cerebral team-based activities might go a long way towards
fighting the stereotype that computer programmers only live in
artificially lit basements eating pizza. That's a physically
damaging lifestyle, nothing to do with writing code or even doing
math.

Regarding last night's tele-class (real time, zoom.us[1]), I
worked through "cloning a github repo" as the core exercise, a
repeat from last week, then went through the process of updating a
notebook live, and pushing the changes back to the repo.
The repo was of course the one with yesterday's Jupyter Notebook
about Ordering Polyhedrons by volume.
https://github.com/4dsolutions/SAISOFT
I tell them "cloning a github repo" is going to be important for
when they want like a Jake Vanderplas tutorial, i.e. when they want
to study a topic in more depth and the workshop is (A) on Youtube or
similar service and (B) the workshop materials are free via github
(a common enough pattern).
I also reminded them how Google shares TensorFlow in the form of
Colab exercises (Jupyter Notebooks).
One students asked "R or Python, which is winning in Data Science"?
My answer: pandas is a relatively recent development and there's
already lots of excellent curriculum based around R, which is
likewise free / open source. The business world is rushing into
Python because of DL / ML and so gains an R-like tool in the
process, which enables better town-gown relations i.e. Harvard can
talk to Facebook about Pytorch thanks to already teaching R in the
stats department.
In other words, it's not either/or, more like two communities
forming a bridge via the common language of data science, which R
and Python both reflect (as do some other languages / ecosystems,
not aiming for comprehensivity here).
