Daylight Saving Time, again….

“…[T]he shift to Daylight Saving Time (DST) results in a dramatic increase in cyberloafing behavior at the national level.”

DT Wagner et al, J Appl Psychol. 2012 Sep;97(5):1068-76

A quarter of the world’s population will be groggy today. A few people will die traumatically. Students’ test skills will deteriorate. A few more people will die of heart attacks. The stock market may crash.

And yet we still do it.

You cannot save time.

You cannot add an hour of sunshine to your day.

You can, though, manipulate human conceits. If nothing else, Daylight Saving Time is an excellent way to demonstrate to children the folly and the real consequences of humans believing they control more than they control.

Tomorrow my 1st period lambs will trudge through before dawn through blackened banks of snow to get to school. Broad Street in Bloomfield will look like the zombie apocalypse. We’ll tell them to keep their heads up (or at least wipe the drool of their desks before they leave), but we are bucking millions of years of evolution.

Humans need sleep. Adolescents (still considered by most to be humans) need more than the 97 minutes my kids average on Sunday nights.

And why not? What better way to prep for college and career readiness in the global economy than making students take life-altering assessments while comatose? Have kids knock down a few Xanax pills, and chase it with gin and Adderall cocktails to make it really authentic.

“About 1 in every 6 high school seniors in the United States has ever had some exposure to prescription stimulants, either medically or nonmedically.”

Yep, a repeat–I ilke cycles….

Black music, white teacher: an apology owed

We  favor blues musicians without testosterone, without teeth, without sight, without color.

Black women, androgynous white men, and old Black men are safer. Old, scratchy vinyl recordings are safer. But we shy away from the Black man in his prime.

The blues are easy to play poorly yet sound good to white ears. The Stones made a living on this.


I was playing Robert Johnson as the seniors strolled into class on Friday. I’ve gotten in the habit of playing music as the day starts, and Robert Johnson was the morning headliner.

The third marking period started a few days ago. The class just had their first quiz. Most failed, not unexpected given it was the first quiz for seniors that did not count. Senioritis has kicked in.

So I sang an off-the-cuff blues piece about senioritis backed by a harmonica riff lifted off YouTube.

And now I realize this was a mistake.

So tomorrow I will start class with an apology. Not for playing Robert Johnson, a fierce blues man who died far too young. Not for singing, though that may warrant a separate kind of apology.

I will apologize for my lack of respect. Using that art form at that moment to entertain students was wrong. It felt off at the moment, but I wasn’t sure why. I thank Justin of objective opinions for his kind reminder.

(Yes, I will still sing and play the blues by myself for myself–but I cannot share what I do not own.)

To “Errorometer” is human

Science is about recognizing when something doesn’t fit a current model of the natural world, which is just about all the time in science. Science is all about telling someone else they’re wrong.

Schooling is all about being “correct” and getting high grades. High school science is an oxymoron. I wrestled with this for years until I met Chris Harbeck, a different kind of teacher.

While sharing pints with a few teachers upstairs at McGinty’s, Chris took a “sip” of Guinness, then tossed out a few words that changed my teaching–

“I give out points for anything, a thousand here, a thousand there. They don’t mean anything.”

The original Errorometer

Print out your Errorometer, laminate it, hang an Expo marker next to it–done.

Simple. Cheap. Effective.

Every time a student gives me a reasonably well thought “wrong” (or even an unusual but “right”) response to anything going on in class, even if only tangentially related to the natural world, a student can put a point up on the Errorometer. For every 10 points, everybody in class gets 10 out of 10 points in the Test/Quiz category.

The COVID no-touch version….

Yep, everybody.
Yep, it diminishes the “value” of points individuals receive on tests.
Yep, everybody’s grade gets a boost.

But, as a wise Canadian math teacher told me over a pint (or three) of Guinness, if points mean nothing (and we agreed that was true), then giving them out freely and frequently means nothing as well.

(The fancier pedagogues among us might even call this metacognition.)
