This one's been answered already, but I'll hammer it home too...
OK, I'll bite. How can a Tango teacher who cannot dance (barring injury and such exceptiions) be a great Tango teacher?????????
By communicating the concepts clearly, and by analysing any problems and fixing them.
Which, of course, applies to every teacher in every discipline. I don't want my son's Maths teacher to be Stephen Hawking, I'd much prefer it if she could, well, teach.
The fallacy that great teachers have to be great dancers is demonstrably false. And in some ways, being a great natural dancer is a disadvantage to teaching.
...if anyone can give a believable defense of this one, I will surrender and you win! :bkick:
Obviously, the teacher should be able to dance to a point - dance is a physical discipline and we learn from watching as much as from listening. But I don't even believe the teacher needs to be a better dancer than the student. Again, the obvious example is sports coaches - Olympic athletes don't demand that their coaches are better at sports than they are, do they?
But another example is an art critic. We don't expect our art critics to be better painters than the people they're critique-ing, do we? Yes, being able to paint to some point is probably essential, but there are far more important skills.
