Who is organizing the opposition to Common Core?

I propose to write a textbook on the subject of geometry:

https://www.researchgate.net/publica...Multiplication

A number of people have expressed an interest in using this book when it is complete and I am already making arrangements for it to be translated into Russian. But here in America it cannot be published because it is not Common Core.

Who is organizing the opposition to Common Core? Publication of this book cannot advance in my own land until Common Core is defeated, so I need to get in touch with the resistance. And I mean teachers, not parents. The latter, while their hearts are in the right place, have made a lot of misinformed statements about Common Core that its proponents like to quote for the purpose of making the opposition look stupid.

But your views on mathematics education are quite unconventional... even if common core were defeated, you would still have to do a lot of work to get the book published.

Math Focus: Analysis
The U.S. Common Core for geometry prohibits teaching students Euclid's five postulates. This may seem incredible to parents who learned geometry from Euclid's Elements, but they can verify that their son's or daughter's textbook nowhere lists these five postulates. Common Core admits that, "Later in college some students develop Euclidean and other geometries carefully from a small set of axioms." But they insist that this is not allowed in high school.

Also, Common Core makes transformations the "spine" of geometry. "In the approach taken here, two geometric figures are defined to be congruent if there is a sequence of rigid motions that carries one onto the other. This is the principle of superposition." But superposition, which Euclid used in Proposition IV and nowhere else has been regarded with suspicion for 2300 years. Many have pointed out that, if it were a viable proof, then it would appear on every page of the Elements, but obviously Euclid was not comfortable with it or he would not have used it only once to get past that initial hump and then then never again.

I begin with a statement of Euclid's five postulates and then base the entire rest of the book only on those postulates and on theorems that I have already proven. Also, I refuse to use superposition but insist on only those axioms accepted in modern abstract algebra. For these two reasons, Common Core forbids the use of my textbook in America.

Calling me "unconventional" is just name calling.

The first thing I notice is that "quadrilateral" is define as "The union of two triangles adjacent on their longest sides". The usual definition is simply "a figure with four sides", "quad" meaning "four" and "lateral" meaning "line" or "side". The two definitions are NOT the same, your definition not counting as "quadrilaterals" many figures that have four sides.

There is nothing interesting about four-sided concave figures and my definition streamlines the many interesting proofs about four-sided convex figures. You can still study four-sided concave figures if you want to; you just can't invoke quadrilateral theory.

BTW About a month ago I reworded that definition slightly, though it is still true that I do not consider four-sided concave figures. You might want to download my paper again. It is an ongoing project - it gets updated all the time.

So basically, this has nothing to do with 'Common Core'. You want to be able to publish a book that expresses your idiosyncrasies. Even if there were no 'Common Core' it is unlikely that any Publisher would be interested.

Yep look it's been great pal excellent work with the publication. You truly are an inspiration to all of us in creating what appears essentially everything I would find if I googled geometry, but in a pdf mixed in with a bunch of spam written by a seemingly incoherent author.

I'm sure that they are at least as interesting as concave figures.

hmmm

cant remember are those the type of lens that cause "eye burny" if its held the wrong way round aimed at the sun or is that convex?
