After all the hard work we’ve deserved a little break 
So here is a good visualization about delinearizing math:
The author pretty recognized the problem pretty well. And as well some of the causes.
But then he skips back to the old “foreshading”, “mystifying” and voodoo-stuff that I joyfully reject. No sacred priest and cleric cast any more! The connections have to be made visible to everyone!
Though his move is very revealing: he can do nothing else. The connections (which he displays very well on the intro picture) are nowhere backupped in the culture. He stands there, being a lonely prophet – no delinearized books exist, only a few mindmaps and he cannot tie the books to one another and you can certainly not tie the teachers to one another. Nor can he step out of his curriculum, because he has to test it. And he has a multitude of pupils facing him, that would probably all follow different links and paths.
He would need something to backup all his ideas. At least a software. And here we go!
