I find this disappointing: Should mathematics course requirements for high school graduation be satisfied by computer science courses?
Allowing a computer science course to substitute for a mathematics course in states with a graduation requirement of only two mathematics courses (beginning with Algebra 1 or the equivalent) would surely undermine students’ mathematics preparation, while doing so in states that require four mathematics courses would be unlikely to have an adverse impact on college and career readiness in mathematics.

Again, though I do understand NCTM's intent, I would like to see them emphasize more the deep relationship that does exist between math and CS.
I agree with much of what you say, Ted!@Kirby: I just had to weigh in on the Singapore comment. 30 years ago the best and brightest in Singapore chose engineering - these days they head for medicine, law, business and finance. See http://www.stjobs.sg/career-resources/personalities/engineering-losing-its-shine-in-singapore/a/199055
Computer science has also taken a dive and most institutions struggle to fill available places.
Considering Singapore is one of the most wired places in the World, math here is largely still taught very conventionally, and very much to meet exam requirements.I give a lot of talks on the issue of technology use in mathematics education here. I get one of 2 responses usually:(a) Those who "get it" sigh and say it will never change because of the exam system; and
(b) The mathematics teachers say "What about the steps? How can we grade them if we can't see the steps?"
The latter case is really the same as Peter's comment - it's all too threatening for them.RegardsMurray

The mathematics education establishment will never change unless it is
forced to. From the first day MathFuture was started it has been on an
inevitable course of eventually needing to bring about a change in the
way mathematics/computer science/symbolic logic is taught by “ramming
[the new educational ideas it came up with] down people’s throats.”
That day has now arrived.
The step-by-step equation solver I have been working on provides us
with a ram that is powerful enough to do the job. I have some
strategies in mind for how to use this ram effectively. The question I
have is are the people on this list willing to go up against the
mathematics education establishment? I definitely am.

My dream was to
become a computer scientist, but I was forced to drop out of the CS
degree I began in college because I could not do the math that was
required. I felt awful about myself for years because I thought I was
too stupid to understand math.
Since I do not have direct access to children, it is difficult for me
to teach MathPiper to children directly. However, over the next month
or two if the people in this group who decide to learn MathPiper want
to experiment with teaching some of it to children, that would be
great. I would be especially interested to receive feedback on how
MathPiper's automatic program grading capabilities work with children.
It would be very useful if the Math Future group could start
collecting and publishing stories from people who had their careers or
self-image damaged by the current approach to teaching mathematics.
Maybe if more people were aware of the amount and seriousness of the
damage that is being caused by the current approach, utilizing the
more extreme "ramming" measures I have in mind might be unnecessary.

Unfortunately politics can be ugly and ruthless, and my course no longer exists. Skipping details, a little over a year ago I experienced what it means to hit the wall, and I am now in early retirement. Reflecting over the last year, I can see that I have been going through a grieving process.The entrenched stupidity that is able to comprehend programming only as a 'tool' that mathematicians might 'use', that it is not an intrinsic mathematical activity in itself, that sure, we can 'use' it, but we shouldn't confuse it with 'math' makes me so deeply furious that I'm brought to tears whenever I now try to write about this. However, that's an improvement. Earlier, I couldn't even write. For years I kept weathering the stupidity thinking that it would change, but it only got worse.

And the ability to "do the math", that is, do the programming, for such models is demonstrably achievable by even elementary-age students. The modeling itself, of course, requires skill and training in "science"; but on the other hand we can't do modern science without modern models, and in our age, that means computers.

Then the rest of education would all be optional.
So I like the idea where students conduct their own investigations (of problems within "systems", as you suggest) because of the possibilities for ownership, appropriate use of technology tools, and creativity - things which are lacking in too many math courses.

The network is the supervisor. The network is able to supervise
children much more effectively than humans can, and this ability is
increasing exponentially. For example, here is a technology that
tracks everyone in a city using a single drone that has a very high
resolution camera:

Every student will be taught by a HAL-9000 like ITS which will be made
available them when they are born. These ITSs will be like the Greek
tutor slaves that wealthy Romans had.
I think this style of education is the one the world is quickly moving
towards. To me the real question is who is going to be in control the
ITSs?

Maybe... I've met my share of sycophantic programmers who just do the bidding of their managers. If we have programmers with enough independence to manage the ITSs without interference, then the world you predict may be possible.
I don't see it being a military project as there you have a culture into following orders. They'd surrender to the AI HAL, probably worship it with candles and churches.

Intelligent Tutoring Systems and experiments like Khan Academy have
shown that technology now makes it possible to bypass conventional
teachers if needed. However, I am hopeful that a significant number of
math teachers will learn and then go on to teach the "New New Math" we
are creating because of its beauty, simplicity, and effectiveness.

I think you are right that science should be put into the mix from the
beginning. Perhaps the ingredients of the Patternmatics mix are simply
Science, Technology, Engineering, and Mathematics taught together from
the very beginning, and logic is the glue that binds these areas
together [1].
Model theory is part of mathematical logic
(https://en.wikipedia.org/wiki/Model_theory) , and I think its simpler
aspects can be taught very early. I have been collecting "new math"
mathematics books that were written in the 1960s, and some of them
have very clear explanations on how mathematical logic and
interpretations work. I am looking forward to putting these "new math"
explanations back into use again.

Before we can determine what the meaning of "product of mass and
velocity" is, we must first determine what the meaning of meaning is.
Since the formal definition of meaning is part of symbolic logic, this
is our starting point for this determination.
What the AI researchers who built the equation solver that I based my
solver on discovered was that people unconsciously use axioms at the
meta-level of algebra (along with meta-level inference) to solve
elementary algebra equations.
I have been thinking about this information and the PDX Code Guild.
After you have learned these meta-level equation solving techniques, I
am convinced you could offer a class on it for experienced
programmers, and interest in it would be so great that it would exceed
the capacity of the facility.

Maybe we can't [ prove ] "the program does what it's supposed to" because we're exploring, not writing to a spec.
Good points Joe.
A lot depends on how we define "engineer", as well as "artist".
This word "artscience" -- all one word -- has some currency (I've seen at least one book by that title, and no, not by Bucky).
The kind of destructive engineering people engage in, undoing what that the constructive types do, is not necessarily controlled, nor predictable in its outcomes.
The atmospheric fission blasts conducted in the course of our planet's first nuclear war were done with full knowledge there were both known and unknown knowns in the picture, not to mention unknown unknowns.
The engineers went ahead anyway and yes, the ripple effects are still being calculated. Like a real number with chaotic digits, we have trouble second guessing the next twist.
As a species, we have centuries of work cut out for us, simply keeping ourselves safe from our new inventory of radio-toxins. Yes some of these occur in nature but some didn't in these quantities. Isotopes r us. I'm a strontium 90 baby.
Or were those tests the work of out-of-control artists?
Semantics matter I guess.
Either way, I agree we need to ponder the consequences of our projects, look before we leap as they say.
Blindly tempting fate to "teach us physics the hard way" is pathological behavior no matter who this "we" is doing it.
So many gentler on-ramps, learning curves, thoughtful curricula, might serve. If we take fuller advantage of what's already in inventory, we might have an easier time making over this planet --something humans are clearly doing, with or without "climate change" (the biosphere has already transformed irrevocably in so many dimensions thanks to hominids, that's no longer debatable).

They say Portland is where "young people go to retire" (that's a joke, started by the TV series Portlandia, which gently mocks Portland in a way Portland somewhat enjoys -- to where everyone in their uncle seems to be looking for digs).
However my experience is young people burn out and need downtown to retrain for something different.
