Now tell us what you meant when you said "Then all three of them have much to answer for." :)

How do you handle units? Like 12 miles or 14 hours?

That's a very good question. How does one handle units in general? What axioms does one use? If there are none, then Robert's earlier question about an exam is well-posed: "Is this mathematics?"
 
How do you show a rational function between polynomials, such that a student can see it and simplify it or factor it?

What on earth is "a rational function between polynomials"? Dare I ask, "Is this mathematics?"?

The word "between" doesn't even appear in the webpage you sent me, and you left both my questions unanswered. Maybe I should answer your question in the same spirit that you answered mine by saying:

They must answer for atoms, coffee, coconuts and tractors.

More seriously, you surely know that colleges and universities have effective procedures in place for dealing with suspect scholarship. Look up the charlatan, Ward Churchill, to find out how they work. (You can start on my own website, at the URL in my sig. After that, Google is your friend.)

Did Bishop and Milgram made any effort to address Boaler's work through those channels---which is what any respectable academic should do when they think they've found such matter. If not, then their vitriolic (a word already employed, quite reasonably, by others) reaction smacks more of vigilantism than of academics.  And that they chose not to do so would hint very strongly at the weakness of their case. 

They could, of course, still do so. But my guess is that they know better.  And they, too, might look up the Churchill case. What it is established that he did is no worse than what they've suggested Boaler did, and if there is truth to their accusations, her university should find it once a formal complaint, which includes the evidence they say they have, is lodged.  And, it is important to note, there is typically no restriction on who may lodge such a complaint.
