Newsflash for Teachers: Being an Asshole is Ineffective

Every time I pick up a science news magazine or book I end up smacking my head in disbelief that science goes to such lengths to prove what everybody else knows already. So being an Asshole is an ineffective approach to teaching. Really, a Nobel Prizewinning scientist said so!  I read it in a random book on randomness: The Drunkard’s Walk by Leonard Mlodinow. The author tells the story of Daniel Kahneman, a psychologist who won the 2002 Nobel Prize in Economics (!). I’ll retell this because here is an interesting twist on “what everybody else knows already”.

While working as a psychology professor at Hebrew University in the 1960s, Kahneman lectured  a group of Israeli air force flight instructors on behavior modification. As a well-read mother of an almost-three year old, I know about behavior modification: rewarding positive behavior works, but punishing mistakes does not. Almost every other parenting book will tell you this. My husband does not agree, but that is another story.

When I read the following passage though, my first connection was not to my son, dear as he is, but to teaching flute. I listen to some teachers brag about how tough they are, and now believe they are driven by a misconception. Perhaps more importantly, this will give us a lesson on how not to talk to ourselves, as we practice for hours on end, give concerts, and play auditions.  I’ll begin quoting from page 7, just mentally replace the word “flight” with “flute”:

Kahneman drove home the point that rewarding positive behavior works but punishing mistakes does not. One of [the pilot instructors] interrupted,…”I’ve often praised people warmly for beautifully executed maneuvers, and the next time they do worse,” the flight instructor said. “And I’ve screamed at people for badly executed maneuvers, and by and large the next time they improve. Don’t tell me that reward works and punishment doesn’t work. My experience contradicts it.” The other flight instructors agreed. To Kahneman the flight instructor’s experiences rang true. On the other hand, Kahneman believed in the animal experiments that demonstrated that reward works better than punishment. […] And then it struck him: the screaming preceded the improvement, but contrary to appearances it did not cause it.

How can that be? The answer lies in a phenomenon called regression toward the mean. That is, in any series of random events an extraordinary event is most likely to be followed, due purely to chance, by a more ordinary one. Here is how it works: The student pilots all had a certain personal ability to fly fighter planes. Raising their skill level involved many factors and required extensive practice, so although their skill was slowly improving through flight training, the change wouldn’t be noticeable from one maneuver to the next. Any especially good or especially poor performance was thus mostly a matter of luck. So if a pilot made an exceptionally good landing – one far above his normal level of performance – then the odds would be good that he would perform closer to his norm – that is, worse – the next day. And if
his instructor had praised him, it would appear that the praise had done no good. But if a pilot made an exceptionally bad landing – […] then the odds would be good that the next day he would perform closer to his norm – that is, better. And if his instructor had a habit of screaming “you clumsy ape” when the student performed poorly, it would appear that his criticism did some good. In this way an apparent pattern would emerge: student performs well, praise does no good; student performs poorly, instructor compares student to lower primate at high volume, student improves. The instructors in Kahneman’s class had concluded that their screaming was a powerful educational tool. In reality it made no difference at all.

So the next time you or anyone else crash and burn, it’s fine to mull it over and figure out what went wrong, but it doesn’t pay to be an asshole about it – especially to yourself. And besides, apes are higher primates, not lower primates.

but I was going for that high D!

Finger Exercises Based on Tai Chi

 This entry is cross posted on the musikFabrik blog
 

Anyone who works with their hands can benefit from the energy flow these exercises provide. I am no expert or student of Tai Chi, but I have had to work a lot at injury prevention. You can do them at the beginning of your warm up, then as necessary during the breaks. Breaks are very important in injury prevention. Any exercise that stretches or gets the energy flowing during your break will allow you to practice more in the long run, and keep your money in your own pocket and not the doctor’s.

I don’t mention the pacing of the exercises in the video. For me, they take four to five minutes to complete. This is a good investment of time when I have a long practice session, especially if there’s much to be done on alto or bass flute. Enjoy!

Why Augmented Scales Kick Butt

Because of the seemingly innocuous combination of half-steps and minor thirds!
It’s one of those symmetrical scales that I just love, although I know nature abhors perfect symmetry, and true beauty (like those lovely Japanese gardens) operates on the principle of slight asymmetry. But for composers, symmetry in the context of tonality is very useful when you don’t want the pull of a tonal center. It frees you up to think of other ways to pull in the audience.

Most of us flutists know some symmetrical scales:
1) Chromatic = half steps repeated
2) Whole Tone = whole steps repeated

Then you may know, especially if you have studied Jazz:
3) Octatonic (a.k.a. Diminished) = either repeating half step/whole step or whole step/half step

And the subject of this blog entry:
4) Augmented scales = either repeating half step/minor third or minor third/half step

You find these scales in music by Dutilleux, Gaubert and if I’m not mistaken Jolivet. That minor third makes things sound sort of “harmonic minor-ey”, pentatonic or bluesy, depending on the context.

But my point is not that they just sound cool, they kick butt because they are seriously challenging to play smoothly! Why?
1) The half steps go naturally quicker than the minor thirds
2) The scales with A#/Bb also have F#/Gb, so you can’t use the Bb thumb with good conscience!

Just try them out!
