I cannot judge Dy/Dan's "personal reasons for avoiding algebra" (if he is indeed doing that).

1. Is it at all possible to *teach* a student (any student) - *creative writing*?
2. If the teacher has created sufficiently imaginative and *creative* plays (which stimulate, perhaps excite, the students to *write creatively*), then I'd believe he has done something valuable.
3. I'd not speculate on the teacher's reasons for adopting the strategy he does/did. So long as the students felt challenged, then I guess both teacher and students have gained something useful.
4. I believe your 'analogy' or 'metaphor' has failed.

Well, IMHO, the real problem (/deficiency) in math education is the one that Salman Khan has not yet resolved - and it is high time the educational system bestirred itself to do that.
Nonetheless: I believe (from a VERY cursory inspection of the Khan Academy's website) that Mr Khan is performing a valuable function that does aid students. In the final analysis, I believe those students who believe they have benefited from Salman Khan's work should be the ones to decide how useful or not useful it is.
I AM glad that you have at last decided to give Mr Khan his correct appellation.
As noted at an earlier post, Khans are fierce warriors and quick to take insult when they feel slighted. I understand that, during the 'First Anglo-Punjab War' (1842 or thereabouts), they once slaughtered some 15,999 British [and Indian!] troops (or so), leaving only one Briton alive to reach Jalalabad. That impelled Rudyard Kipling to come out with literally VOLUMES of jingoistic poems praising British valor. Of course, he conveniently ignored the fact that most of the 15,999 slaughtered (about 90%, it is said) were Indian soldiers serving with the British.
Of course, this was not exceptional behavior on the part of the British. I remember there was a marvelous take-off on Churchill's famous speech made in the House of Commons after Dunkirk, which went something like this:
"...We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender - we shall fight to the last Indian soldier!"

I'm afraid I don't quite understand what you mean.

As I've often stated, the 'teaching' does not exist by itself. We really do need to start thinking in terms of the 'dyad' "teaching+learning". The revolution that Donald Sauter is seeking would, I claim, develop very rapidly from that 'minor' change in attitude on the part of the 'educational system'. Your Fourier optics professor seemed to have simply ignored the 'learning part' of the dyad. You are very kind indeed to certify him as a "decent and enthusiastic teacher".
