Pediatrics vs. teaching


I used to be a doctor, the kind with a stethoscope, the kind licensed to hurt you for you own good. It puzzles children to learn that a physician would walk away from medicine in order to teach, and there are days I am baffled myself.

I liked medicine. I love teaching. I did not know that this would be true when I left medicine, so while it is true, it is not enough to explain why I left. Why leave something you like, especially when it pays ridiculously well?

Every year children ask me this, and so far I have not quite gotten it right. I thought I had it right, but high school sophomores would kind of shake just a little bit sideways. I wasn't fooling them.

I think I got it right now.
***

I saw a lot of bad stuff in hospitals. I saw a lot of good stuff, too, but good stuff can be found in a lot of places. The truly bad stuff has a home in the hospital.

  • The unlucky (an elderly woman who slowly died from an infection caused by an errant piece of metal ripping through her car's floor, riveting in her thigh).
  • The doomed (a woman burned over most of her body, still conscious, still talking, immediately before we intubated her, rendering her speechless--we knew she was doomed when we did this. We did it anyway.)
  • The curious (two babies sharing the same torso, the same heart, the same fate).
  • The geographically screwed (an Asian toddler who needed a new heart, but who could not afford one, twisting away towards death as she lived in an American hospital as an alien).
  • The innocent (children wasting away from a virus we barely understood, acquired from a mother's heroin habit or her lover's proclivities).

I was very good at diagnosis, and not bad at making things better once a diagnosis was made. A few were better than me, but not many.
***

 When you are surrounded by hurt, there are two ways to respond if you want to remain functional--fix it, or pretend it does not exist. I did a lot of fixing.

If you do medicine long enough, and if you are paying attention, you give death its due. It's real, it's usually ugly, and it's inevitable.


I can't beat death--took me awhile to get to that realization, but I got there. And it's liberating.

Turns out living isn't the goal--living well is what matters.

I was pretty good at helping people live longer. Now I'm getting good at helping people live well.

I thought my job mattered before, but had my doubts in the pitiful wail of a dying toddler, bruised and bleeding as we laid our hands, our technology, and finally our fists in futile CPR on her tiny body as it cooled its way back to entropy.

A life worth living is our only compensation against the greedy hand of death.

So I help children carve out a life worth living.

I'm a teacher.




If you teach, teach as though lives depend on it. If you think this is excessive, get out.

Put the shoe on the other foot

I haven't worn shoes since the graduation on June 21st, which means I've gotten through the summer without a wake or a wedding.

My feet share the story of summer--they're currently encrusted with the oozy remains of an ill-advised tromp through poison ivy.The tops are brown from melanin, the bottoms brown from dirt. You could make a decent baseball mitt from the leather that lines my soles.

I feel the world differently than I would if I spent my days in shoes. Not saying any better or worse, just different. But once we establish that there is a difference, then we can talk about values.

The kids who live their lives shodless  live a different life than those who live with their shoelaces lashed on tight.

While we dither on about content and standards, the climate you set in your classroom may have profound effects on the way a child see the world, effects that last long after a child has forgotten Pythagoras' theorem.


I'm not saying a child should go barefoot in your classroom. I am saying that before you bind her feet into shoes, you'd better have a better reason than because that's the way it's always been done (a silly reason), or for health (a false reason), or because you said so (abuse of power), or because it's a school rule (an arbitrary reason).

School starts this week for many of us here in New Jersey. Teachers will spend hours droning on about rules. Most high school kids will have less than 5 hours sleep the night before the first day of school and they know all the rules anyway.It's an easy day to waste.

Shake them up a bit. Tell the kids they're required to take off their shoes. Or that they must put their right shoe on their left foot. Or that they must put their socks over their shoes.

Let them tell you why they'd rather not.





(Good Lord, I'm speaking metaphorically....)

In Irene's aftermath

The sandpiper did the unthinkable--it strolled. Then stopped. Then sat at the edge of the ocean. I was sitting a yard or so behind it. It did not matter. This bird is done.

Hurricanes are exhausting.

***

We're more intricately tied to nature than we care to admit. We do a pretty good job denying death and denying age, our little pleasure machines adept at creating the illusion of a perpetually orderly universe.

I write out a word--say "maple"--and the branch I swung from as a child still feels as lithe in my hands, though that branch turned brittle and broke decades ago, its essence long turned back to carbon dioxide and water, gone long before the most recent hurricane, but still vivid in a word.

I do not know how much fear a sandpiper feels sitting exhausted by the edge of the Atlantic, a sandpiper that may only exist now as a word--"sandpiper"--forever etched in my brain, "forever" itself a human conceit. It's carcass now lies just below the tide line, nibbled on by crabs and snails.

When we teach science, we must be wary of our worship of our words, our models, our abstract representations which become more real than the ground under our feet.

The point of science is just that--to look at the ground beneath our feet, for whatever it is, as it is, or as best we can tell what that is is.

If our feet leave the ground, and we chase our conceits instead of the dirt, we lose a chance at something bigger. Scientists know this. So do good poets, of course. Neither get a fair hearing in schools.

We spend so much time deflecting what's true we lose our grip on what matters.

There are a lot of ways to get there--John Steinbeck was a better observer than I'll ever be. The point of biology is not to learn vocabulary any more than the point of reading Steinbeck is to learn sentence structure. The point is to get to what matters.

You might see it in the fading light of a late August sunset a day after a hurricane watching a sand piper rest its weary body on the wet sand. You might hear it in the dying voice of Johnny Cash singing "Hurt." You might smell it in the decay of an early September breeze.



You'll know when you get there.




Your students will, too.

Zeitgeber matters

We keep time in class, as we do pretty much everywhere. We pretend that days are exactly 24 hours long, and that each hour is as well proscribed and linear as he next. An hour in December lasts exactly as long as an hour in June.

Kids know otherwise, of course, at least until we train them.

We start school here in Bloomfield next week. The daylight hours shrink dramatically this time of year. A week from now we'll have almost 20 minutes less daylight than we'll have today. In a month, we'll have an hour and 20 minutes more darkness. The light we do get will be more oblique, less intense.

Science teachers will make a big deal about this, explaining the seasons using globes and lamps, but if we've taught our children that sunlight does not matter, that the clock matters more than your hypothalamus, that we eat at noon, not when you're hungry, well, then, we should stop feigning shock when children really don't pay much attention to sunlight.

None of the adults around them do, either.

If college graduates do not know why seasons happen, or how trees accumulate mass, or what forces act on a basketball in flight, maybe it's not because our children refuse to learn.

Maybe it's because they internalized what we've been teaching them all along....









New leaf--if more than a few children are truly uninterested in a topic, and I have no good reason to push them, drop the topic.

Science and the art of Perrymandering

I could be a Rastafarian, a witch, or a Hindu. Maybe I'm a Jainist, a Buddhist, or a Scientologist. I might worship the sun, the moon, or maybe even both.

As a science teacher, it matters not a whit.

And here we have potential future Presidents insisting that Intelligent Design belongs in my science class.

I spend a lot of time defining science, more time than many, but it's time well spent. If you have no idea what science is, then either learn or, well, clam up.








Truth be told, I'm mostly a pre-Constantinian primitive Christian, who happens to be confirmed a Roman Catholic.

No Khan Do

Salman Khan makes educational videos, lots of educational videos, using a simple technique--he draws out his thoughts on a "blackboard," while he thinks aloud. Much like someone unwrapping a problem on a napkin or on an old slate blackboard.


Bill Gates has practically adopted him, and the ed reformerati love him. He's an MIT grad, he's multicultural, he's an ex-hedge fund manager (maybe his biggest cachet, a sad reflection of our culture), and he's kinda cute. In an Ivy League rules kind of way. (What do I know, I used to be a stevedore....)

Sal Khan helps kids learn how to regurgitate what we already have in textbooks, without reading the textbooks, a video CliffsNotes for the now generation. He allows the worst parts of education to be efficiently streamlined for ingestion, about as effective and useful as cod liver oil. It works, but it's over-rated.

In the end, I think it's a student's ability to pause, rewind, and rehash what Khan says that makes him so valuable, and which makes his brand so sad--really, really sad. I'm a teacher, and a pretty good one. We need to pay attention to what our kids don't know.

If 21st century learning boils down to a hyped up version of what we did back in the 1930's, we're screwed. If Bill Gates is the valued judge of what education means (go learn his history), we're screwed. If we cannot do better in the classroom than Mr. Khan can do with his SmoothDraw and Camtasia (or what any of us can do on the back of a cocktail napkin), we're screwed.

Relax, we're not screwed (yet). Be better than the videos, not a hard task, unless regurgitation floats your boat.

Seine thoughts

Went seining yesterday with my brother and my niece, dragging our net along the edge of the Delaware Bay looking for whatever.



We found lady crabs, spearing, a croaker fry, lots of comb jellies, a  blue claw, a few hermit crabs, and a horseshoe crab molt.

We were looking for nothing in particular, and we found it. A few kids and their parents joined us--looking for nothing in particular trumps searching for something specific on a fine August afternoon.
***

School starts again in a couple of weeks.

Schedules. Bells. Curricula. Because that's the way it's done.Because it's efficient. Because it's orderly. Because we have to. Because we need control.

It's not how we learn, though, and never has been.

Several children felt the wiggling of minnows in their hands yesterday, the weight of warm, gooey comb jellies, the snip of crotchety crabs. It's unlikely they will seine in school, even in biology class.

And that's a shame.



You can get a decent  4x8' seine net and a pair of oak poles for about $30.
It will outlast the laptop you bought your child last week.
If taken care of properly, it might even outlast you.

Breaking down biology

Thermodynamics started out as steam punk physics, but now explains, well, everything.

There is a non-trivial element of faith the the Second Law of Thermodynamics, one we dance around when we toss the idea of the Big Bang around in science class. Every time there's an energy exchange in a closed system there's less useful energy available to do work--and that's the natural world in a nutshell.

Everything eventually falls apart, drifts to a state of uselessness.





From The Onion,


If students spent any time delving into the implications of that, they'd go from the nutshell to the nuthouse. Instead we toss serious equations at them, with serious sounding names for all the serious parts, and we got them playing in abstract la-la land, which is a fine place to be in you've studied physics for years, but a psyche-killer for the neophytes.

How did the energy get packed into a point billions of years ago? We have a don't ask, don't tell policy.  That kids blithely except the concept of the universe contracted to a point just assures me no one's really paying attention.

My goal this year? Get them paying attention.


So here's my question for the more experienced out there. Would it be crazy to design the biology course around the Second Law of Thermodynamics, starting out each class every day with a brief discussion of how energy transformations guide everything in biology?

Evolution is the Big Daddy of Biology--should I spend as much time on Grandpa Entropy?





I'm not going to lie to you--first time I saw this photo I thought it was a real protest. Things have gotten that crazy.

Hiroshima


広島



Sixteen hours ago an American airplane dropped one bomb on Hiroshima, an important Japanese army base. ... It is an atomic bomb. It is a harnessing of the basic power of the universe. . . . What has been done is the greatest achievement of organized science in history.


It happened on this date, this "greatest achievement."




New technology used to "solve" an old problem. We cannot help ourselves.

Wes Jackson, founder of the Land Institute, suggested "we ought to stay out of the nuclei." Until we have a clue what we want, sounds like good advice.

You cannot separate tools from the critters who use them. Teaching science as some compartmentalized thought process without cultural context is a dangerous game.

What is our responsibility as teachers of science?
As citizens of the United States?
As human beings?

***


This morning I saw a wasp dragging paralyzed cricket along the edge of the driveway. The wasp was not much bigger than the cricket, and the wasp struggled. At one point she let go, stepped back a few inches, stroked her head a few times (much like a human facing a big task), and eventually dragged it down a hole by the driveway garden. The cricket was still alive, but paralyzed.

I did not intervene.

The wasp will lay her eggs in the cricket, and they will hatch in the cricket, still alive, and the cricket will, of course, suffer.

I did not intervene.

The larva wasp will use the the cricket, still alive, for food.

And still, I did not intervene.

We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now, I am become Death, the destroyer of worlds." I suppose we all thought that one way or another.

He sent me the this video:



And now I teach science to (very) young adults. I have a responsibility to them, to the state, to myself.

Harry S. Truman called the bombing of Hiroshima "the greatest achievement of organized science." If that does not give you pause, you should not be teaching science.

You should not be teaching anything at all.

Unanticipated, but not unnatural

CO2 is denser than air. This is easily demonstrated in class.

Combine vinegar and baking soda together in a beaker to generate the gas. The students will groan. Yeah, we know this already, it bubbles.... Ask them what bubbles, and they will tell you what everybody already "knows"--carbon dioxide.

Now light a candle. As a diversion, ask them what gasses are emitted (CO2, H20), then hold the beaker over the lit candle, and "pour" out the CO2, leaving the foamy liquid.

A second or two later, the flame dies, as if sucked back into the wick.

What happened?
***

Just a few hours ago, hundreds of dragonflies swooped around us in the dying dusk. A cold front had just passed through, and the critters were feasting on the swarming insects trapped at the bay's edge, where horseshoe crabs have just about finished their annual orgy.

Dragonflies and horseshoe crabs both came through the Great Dying, a quarter billion years ago. Most of life was destroyed in an event far more extreme than the last mass extinction that ended the age of dinosaurs.

Though it's not clear what happened, extreme CO2 levels likely played a role. CO2 snuffs fires, CO2 snuffs life.

This August marks the 25th anniversary of the Lake Nyos disaster--over 1700 humans killed in Cameroon by a cloud of carbon dioxide exploding out of the lake in a 100 yard high watery mountain of foam, as tall as Manhattan's Trinity Church, the gas suddenly released like the effervescence of  millions upon millions of bottles of seltzer.

The heavy gas flowed down the walls of the volcanic lake that released it, a deadly spree, depriving the living of oxygen as it pushed up the lighter air.


Unanticipated, but not unnatural.

Some locals briefly attributed the devastation to Mami Wata, to a neutron bomb, to "strange Europeans...heavy-set, menacing Nordic...motorcyclists" seen just before the explosion. The eruption had been predicted by a healer who himself did not survive.
***

251 million years ago, carbon dioxide obliterated over 90% of the species around at that time. So little plant life grew that there's a "coal gap" in the fossil record--a 10 million year span where no coal was formed. And yet, the dragonfly line persisted, the horseshoe crabs, too.

These ancient creatures once frightened me with their compound eyes, their complex symmetries, their deliberate living, their bodies so perfectly fit for their niches that little has changed in hundreds of millions of years.


In biology, perfect life does not exist. In biology, the environment defines those who are less imperfect.

But if perfection does exist in life, if there are life forms that will continue to see the dying dusk so long as the sun casts its energy on Earth, it might be found in the creatures that share edge of the Delaware Bay, the bizarre ancient forms of the dragonfly, the slow creep of the horseshoe crab.

I do not know how many of us know the story of Lake Nyos, the stories of Mami Wata, the stories of the horseshoe crabs and the dragonflies, the story of the Great Dying so long ago.

Something so simple as the gas brewed from baking soda and vinegar can silently kill something as complex as a mammal. Next time I snuff a flame with CO2, I will share the story of Lake Nyos, of the Great Dying--these are the stories that define us, stories that may someday save us.







Our stories make us worth saving.

Better safe than sorry?

One of my more vivid memories of childhood was woozily walking around the monkey bars one morning, my head stuck with my nose pointing to the sky, perplexed by my inability to yell, or make any noise at all. Just seconds before I had been happily hanging upside down, tooting on my tin whistle.

I pulled the tin whistle out of my throat, and had enough sense to keep quiet about it. My folks had little tolerance for any consequences from acting stupid. By afternoon I was swinging upside down again, this time without my whistle, my voice now raspy.

At this moment, my left thumb has a small (but gaping) laceration from a saw that slipped from the limb I was cutting a few days ago. I was at the top of a ladder at the time.

I thought I liked heights despite my history--turns out my adventures may have contributed to my relative fearlessness.

"Paradoxically, we [Drs. Sanseter and Kennair] posit that our fear of children being harmed by mostly harmless injuries may result in more fearful children  and increased levels of psychopathology."


"Girls' playground, Harriet Island," circa 1905

We broke a few bones, collected quite a few stitches, scraped off some skin, nearly drowned a few times, chipped (and lost) a few teeth, burned ourselves regularly, and spent part of an afternoon stone deaf after getting a fuseless M80 to demonstrate the 2nd Law of Thermodynamics a foot or two away from our faces.

We got chewed, stung, or nipped by skeeters, crabs, bees and wasps, jellyfish, a bluefish or two. I even got a catfish stuck on my leg for hours, refusing to go for help as the critter shuddered away its last few hours, in a worse state than me.

We knew what tendons looked like from direct experience. ("Look, mom...!")

I'm not advocating that we maim our children, and our gang was a little nutty even by the standards of 4 or 5 decades ago. You could reconstruct a fair-sized toddler from all the cells we lost along the way.

We developed fearlessness, and we learned the difference between risk and recklessness. I even learned a bit about the anatomy of the larynx.

Fear can kill life long before a child's last breath. Fear has tempered some of the flash and bang once a staple in science class. Fear of failing has replaced the kinds of fear that shaped the pursuit of happy and fulfilling lives.

Solstice graduation

"The eye of man hath not heard, the ear of man hath not seen, man’s hand is not able to taste, his tongue to conceive, nor his heart to report, what my dream was."



Except in June.

Just about every day this week I grabbed a few small, dark cherries from the small trees lining Liberty Street--just the right bitterness to counter the almost too rich fruitiness. The sun seems to have frozen in the north, teetering a week or two before starting our slow plunge back to darkness.

Life brims mid-June, feeding on the energy that bathes the Earth this time of year. The energy starts to dwindle tomorrow. Tonight I put my shoes away for the summer,unless, of course, there'a a wake. I took them off as I left our graduation ceremony. The ice returns in just a few months, as inevitable as the wakes that keep my shoes busy.

If you pay attention to these things, the dwindling light, the mad dancing of organisms in the June dusk, the aroma of honeysuckle drifting through your skull, the incessant buzzing of hundreds, thousands of critters aware of you, you'd go mad, of course, a Mid-Summer's Night Dream kind of insanity,

And many of us do--pay attention and go mad--mid-June, midsummer, when living requires little, as fine a time as any to toss a class of young adults out into the world.

And how many are "college and career-ready"? Not sure what that even means.

But I am sure of this--several hundred children from many different cultures, from many different lands, from many different circumstance, left our building tonight having an idea of what is possible, of what democracy can look like. A lot of them left our building "college ready" for schools they cannot afford, and "career ready" for jobs that left north Jersey a generation ago.

They are kind, they are brave, they are bright, and they are now adults entering a world Arne does not (or will not) recognize. As we turn inexorably to November, to darkness, to fear, I hope that a child's new-found knowledge of how the natural world gives her pause before she plunges into cynicism, or to self-loathing.

It's a beautiful world out there, but a world defined by limits imposed by our sun, our soil, or water. Our children are of this world, so long as they live. This matters more than any games imposed by wealthy gentlemen governing from hundreds of miles away.

Congratulations to our Class of 2011. This is your world, get to know it beyond the boundaries imposed by human words and limited ideas. Embrace it like you own it.

Because you do.

June ramblings

I'm reading Umberto Eco, a June indulgence. He's bright, and interesting, and mostly right, but he's also, well, um, a professional dilettante. I have nothing against dilettantes. in another lifetime I'd consider being one, but in a time when honest folks can't find a job, dilettantes seem obscene.

But if you have the time, he's worth a read.
***

In Language and Lunacies, he argues, among other things, that we believe, "as factual truth, that the chemical composition of water is H2O." We teach it as such, but it's not true.

Imagine a solitary molecule of water--what properties could it possibly possess? It would have to be gaseous, since it has no connection with its neighbors, and even then, alone, it really has no special qualities.

Water behaves as water because water has an unusual attraction to itself--the Brittney Spears of molecules. We call this hydrogen bonding, but no matter. Without other water molecules around, the concept of H2O is a human conceit. (To be fair, it's a human conceit anyway, but not in the sense that Mr. Umberto recognizes.)
***

I will bore the love of my life with this tonight--I will prattle on, so I will save you the grief. But I will say this much.

If you think you know anything about water because you call it H2O, you are mistaken. Calling it "H2O" only means that you know it takes two parts of hydrogen for every part of oxygen, and few of us take the time to accurately measure how much water gets generated every time we blow up some hydrogen.

We practice a lot of pseudo-science in education. We encourage an Asperger's Syndrome culture, spouting off "facts," without any connection to the ground that's under my bare feet as I write.

We really know nothing, and that's OK, so long as we remember that the stories we tell are resurrections of the stories told by pretty much any vertebrate with a brain. "I'm here! I'm here! Listen to me! Listen to me! I have a story to tell!"
***

Which brings me to the Big Bang. This is a wonderful story--we have characters and drama and intrigue--but ultimately it is absolutely (and I do not use the term loosely) incomprehensible. If you tell a child that the universe erupted from a single point, and that child dutifully records such nonsense in her notebook, and you let her without letting her in on the secret, then you may as well teach astrology.

And a lot of us are teaching astrology.

Astrology's interesting, but not nearly as interesting as a teaspoon of soil, a drop of water from the Delaware Bay, the purple shit of a common robin.


If science does noting else, it should remind a child that the universe exceeds our imaginations, and that the stories derived from the natural world , our stories, exceed the stories about humans alone.

Most cultures know this. Our culture mastered metallurgy, and weaponry, and we forgot. God help any culture that is bold enough to remember. We destroyed the Amerinds, the Incas, the Aztecs, the Afri. Don't screw with us. We shoot, then let God sort out the souls.
***

As I write this, a robin dances a couple of yards away from me as I water the garden. He's a couple of years old--he knows me, and I know him. I could make up a tale, anthropomorphize him, but that would require a huge assumption, that I know more about him than I do.

If you're going to teach in any way that matters, you're going to have to challenge assumptions.

So this is what I know.  When I water my garden, he eats worms that erupt from the earth. He's alive, I'm alive, and we share the same mitochondria, the same ribosomes, the same ancestors. We're cousins.

If you internalize this, you're less likely to wipe him out. If you're less likely to wipe him out than the Eurodescendant next to you, you're less likely to have a seat at a boardroom table.
***

So I teach.

The commissioner of education in this fine state calls me an "ankle biter." I doubt that Arne knows who I am, but I also doubt that his view of me would be any more flattering than our commissioner's. '

At least one robin loves me, a few mature humans, and maybe even a child or two.

That a child even needs a gateway to the world, the natural, real world outside the pixels that damn her to a life of drudgery and limited choices, is sad. But she does. And I consider it an honor to be that gateway.

Arne doesn't know this world, nor does Bill or Eli or the Acting Commissioner of Education here in the Garden State.

But I do.

And so will every child that walks into my classroom.






I love June. I'm brave in June
Lord, please, let mebe brave when the sun runs away again....

Arne in June

Mid-June.

The blueberries are still mostly green, just blue enough to remind me of Uranus through our scope.

Raspberries and snow peas and basil and purple beans explode in our mouths, in our brains.

Light, light, and more light floods us daily--anything is possible in June, anything. There's enough energy for all of us who survived the past winter, more than enough.

"Enough" is a wonderful word foreign to many of us. If you know "enough," you know "content."

Less than a week ago, a dolphin eyed me, and I eyed it back. Not much to say, even if we could speak the same language. It's June, and there's more than enough to go around.

***

I am reading Science for All Americans, the AAAS book describing Project 2061. The second paragraph starts with this:

Education has no higher purpose than preparing people to lead personally fulfilling and responsible lives. For its part, science education...should help students to develop the understandings and habits of mind they need to become compassionate human beings able to think.

Amen.

Are you listening, Arne? Bill? Eli?

In June, the words of the powerful sound silly--but come November, when darkness falls and fear, again, prevails, Arne will cast his spell again.


Without fear, Arne loses his grip. Without fear, we can teach again. Without fear, we can resume this great experiment.

Puny men can only rule through fear. I'm done worrying. I'm going to teach science.

How about you?





The key to all this is recognizing our own mortality.
Get that down, and Arne's just another semi-pro basketball player with connections.

Why "Johnny Appleseed"? It's June...why not?


And no, Chris Cerf did not invite me back.

A modest proposal

The Science Goddess recently wrote a powerful post pointing out that we're not going to get far with the wolves running the show unless we put on some wolf's clothing.

I save that kind of entertainment for Bleeker Street late October. I got snowpeas to harvest, clams to rake. But she makes a good point. What we're doing isn't going to work.


If more than a few of us get really good at what we do, and our lambs learn to think critically, we're going to be OK. If not, we're toast.

If it's testing the Feds want, let's give it to them:
Test teachers every two months for content knowledge. Heck, test them every two weeks if it keeps the bean counters happy. Most of us will do just fine. The few of us that don't know our stuff, well, time to go.

Put cameras and microphones in our rooms. Put them in the hallways. Install a toilet-cam for all I care. Watch what we do. If you have a better plan, let me hear it. If I'm not reciting state standards while washing my hands in the bathroom, dock me an hour's pay and give to Pearson or ETS or whomever--as long as you leave me alone when I get it right.

Let's make the student testing truly high stakes--if a child fails, off to the gallows! Everyone wins! The district sheds the stragglers, the parents shed a lifetime of debt owed to child's college, and the child does not face a life of shame knowing he let the United States down because some child in Burma kicked his arse.

I doubt Arne's been paying attention, but the obsjay have been ippedshay overseasay. Maybe we can get export Arne's job over to Finland.

This song's been ripping through my head, not sure why, my cortex hasn't caught up with my amygdala, but I suspect The Science Goddess' post has something to do with it:




Joe Strummer's dead, and will be for a bit.
I'm not, not yet, and hopefully won't be for a bit.

I'll take truth wherever I can find it these days.






Truth will out.

Obvious, but not intuitive

Frank Noschese and Rhett Allain have a good on-going discussion on the Khan Academy's  work with physics. Some excerpts:



Science is obvious, but it's not intuitive. Obvious in the sense that we can observe what we observe, even as our brains refuse to accept it.

Intuition kept us alive for thousands of generations. There may be real survival value in accepting cultural illusions, even when they conflict with our empirical data. The concept of god(s) long preceded our worship of data.

We forget this at our peril. We did not survive as the simians we are by applying logic; we survived through intuition. We feel we are right, even when we're not.
***

The past three years, I have started class the same way. I climb up on a lab table, holding a paper clip in one hand, an old edition of the CRC Handbook of Chemistry and Physics in the other. I feel the heaviness of the ancient book, over 2000 pages being pulled towards the Earth. I barely feel the paper clip.

The kids (predictably) assert that the book will hit the ground first. I know in my gut that the book will hit first.
They both hit the floor simultaneously. I am surprised, as I always am. Obvious. But not intuitive.

Even after hundreds of trials, I still  feel cognitive dissonance. I'm an odd duck--I like cognitive dissonance.
 ***

The visceral trumps the cerebral in our culture. One of the ironies of Achieve.org pushing for their new science standards is that their preamble eschews reason:

"There is no doubt that science—and science education—is central to the lives of all Americans."
No, not true. Not even close. But it feels right.

Science is at the heart of the United States’ ability to compete and lead, which of course means that all students—whether they become technicians in a lab, PhD researchers or simply consumers—must all have a solid K-12 science education.
Science matters, but not because of some abstract flag-waving piece of jingoistic nonsense. The second half of the sentence is a non sequitur--unless our being "simple consumers" both requires a solid science education (I would argue otherwise) and leads to the heart of America's "ability to compete and lead."


Science also drives innovation, which in turn drives the economy.
Science certainly drives some innovation, and some innovation has some effect on the economy, but we're still bound to the earth, to the air, to the water more than we are bound to the kind of abstract economy the Achieve.org folks appear to worship.

If we're teaching children science simply because we're holding them accountable for the success of our economy, we are guilty of abusing our children.


Just a few hours ago a pod of dolphins snorted just a few feet from our kayaks.

Nowhere in the preamble does Achieve.org speak of the wonders of this natural world, of the joys of discovery, of our human need to lift up stones to see what lives underneath.

If I do my job well, that is, if I teach a child science, she will scoff at the premises Achieve.org holds as sacrosanct. If I do it really well, she will scoff at any premises I hold sacrosanct.






Is there no joy in Mudville?

Slow science

"[I]t is quite the rushing through and pointing at.... "
A wise woman's words upon reviewing Newark's 2nd grade science curriculum



If you spend most of your time doing things you like, there is no reason to do things quickly. I like slow. Deep, thoughtful living takes time.

Slow gardening. Slow teaching. Slow clamming. Slow cooking. Slow down.


The Framework For Science Education will be released in the next week or so. It is currently "undergoing a confidential external review by a group of independent experts," but given the track record of Achieve, I doubt much will be changed. And that's a shame.

There's a whole lot of "rushing through and pointing at."
***

We keep confusing attainment of benchmarks based on science content with learning science. The persistence of the flawed concept of  a STEM (Science/Technology/Engineering/Mathematics) curriculum shows how little science is understood.

Science is making sense of the natural world by telling stories using specific rules. Models, hypotheses, theories, simulations--all stories dependent on observations of the natural world, the world perceived by our senses, the dancing shadows in Plato's cave.

The heart of science, what separates it from other forms of story-telling, is its reliance on observation. Each and every one of us can see the shadows dancing on the cave wall, and each can challenge the stories of another, by pointing to the wall. Even children. Maybe especially children.

We underestimate the power of naming, a real danger in our early grade science curriculum. I hold sophomores spellbound describing the mysterious force savallah. a mysterious force recognized by my ancestors in western Ireland. I might even light a candle as I tell the story. I explicitly describe what gravity does, but call it "savallah." Every particle of matter tugs at every other particle that exists.



Not one student believe savallah exists. Not one. But they all "believe in" gravity.

Young children do not need to "know" gravity--the word should be banned before high school. They do not need to know engineering. They do not need to know algebra.

They need to practice observing until they trust their perceptions enough to challenge the misconceptions of others.

I spent last evening on the ferry jetty. I saw an eel swim languidly by, rising from the depths, as the gray clouds started spitting on the water, an eel perhaps never seen by a human. The world is far larger than we can imagine.

Learning science is not linear--children need not (and, at any rate, cannot) grasp STEM concepts in carefully chunked modules divided by grades. If a child learns how to observe, truly observe, she can tackle most of the standards proposed in the late elementary grades in less than a month in high school.



If she also learns how to think, truly think, she can tackle pretty much anything. Anything. Content in science becomes old news because it will always remain an incomplete story. We teach it anyway, superficially, and we test it anyway, superficially. Efficiently, cheaply, and superficially.

We don't need children who can recite the stories, we need children who can write them.

In the end, technology will not save us, nor will engineering. Seems the height of insanity to trust the methods that got us into this mess.

What will save us is a generation of children who learn how to observe, to tell stories, to know enough about this marvelous world to love it, and to care for it.







Science isn't intuitive--if it were, we'd still be ruled by a slew of false gods.
Because we do not teach it well, we are still, alas, ruled by a slew of false gods.

Another year ends

We're winding down.

Tomorrow I will wander over to the windowsill, pluck a few snowpeas who know only our classroom, and eat them. I will remind the students that their breath was combined with water, using the energy of the sun.



Communion without fanfare, a miracle unrecognized.

And if a few students leave class this week, our last few days of class, pondering the mystery of biology, the flow of energy, the flow of life, well, I've done my job.
***

I spent countless hours as a child trying to figure out transubstantiation. The wafer tasted like, well, a wafer, but the priest assured me it was the body of Christ.

In my head I imagine molecule after molecule substituting another. I did not know the concept did not originate until a thousand years after Christ's death.

This is my body.

And it is, complex organic molecules fused together by plants, abetted by the nitrogen fixing abilities of bacteria. In physical terms, at the molecular level, we are, truly, what we eat.

And everything we eat ultimately gets back to plants. OK, sunlight. Well, yeah, to something over 10 billion years ago.
***

We had some births in class, we had some deaths. Most of our tanks are unfiltered, unprocessed--light in, air in, and the occasional flakes of crushed shrimp. We have 2nd generation peas and wheat and fish and third generation snails and umpteenth generation of transformed bacteria that fluoresce.

We have the shells of horseshoe crabs and land snails, starfish and whelk.

Our class witnessed a starfish consume a snail, a shrimp snack on a hermit crab. None of this planned, all of it inevitable.

I am not a particularly religious man. My faith rests in the sun, in the plants, in life. I do not pretend to grasp the why of anything in science, and I do not ask my students to grasp anything I cannot see myself.

We do a lot of observation in B362. We see more than we can understand. We form hypotheses, we see hypotheses smashed, and we form new hypotheses.

I'm not sure how my lambs did on the state test, though historically they do well enough.

They leave my classroom more confused now than when they entered back in September.
And that's OK. That was the goal.






The world is, well, awesome. A fresh snowpea of a windowsill plant tells me so.

First lightning bug

I run this every June, because I like lightning bugs.



First lightning bug tonight. I never tire of lightning bugs.

I

Dusk settled on the lake. I could hear the kiss of bluegills as they sucked down insects struggling on the surface.

A few lightning bugs flashed above the mirrored surface. Attracted by their own reflections, they swooped ever closer to the lightning bugs flashing below them.

Fish may not be smart, but they're not all get-out stupid, either. And a bluegill will jump if hungry enough. A few were hungry enough. Inside their bellies glowed a few foolish lightning bugs.

Lightning bug light is cool-literally. Luciferin combines with ATP, the energy molecule of life--the resulting compound combines with oxygen, catalyzed by luciferase, and light results. Even tiny amounts of ATP will cause luciferin to light, as long as oxygen is present. While man has never been to Mars, bits of lightning bugs have--luciferin is an extremely sensitive detector of ATP. If it flashes, carbon-based life may be present.


Luciferase from the North American firefly (Photinus pyralis) is the enzyme of choice for reporter gene assays. Luciferase catalyzes the oxidation of a firefly-specific substrate called luciferin to produce light. This reaction is extremely efficient and the quantum yield is the highest of any characterized bioluminescent reaction. The bright signal makes this a valuable enzyme to use for reporting promotor activity. • Packard’s LucLite® assay system, introduced in 1994, produces a long lived glow type signal with a [half-life] of several hours, which makes it ideal for use in noninjector based HTS luminometers, like the Packard TopCount® NXT Microplate Scintillation and Luminescence Counter or the Packard LumiCount® Microplate Luminometer.

Scientist have yet to synthesize luciferin, so they buy lightning bugs.

My daughter dug out a tiny mudhole for me in our backyard. At dusk, I sit opposite the pokeweed I am learning to like, under a stray white birch I have always liked. Lightning bugs arise from the earth, flashing their "J"'s, looking for love. Harry Potter, like the Bible, makes sense sitting outside on an early June evening.

I read until the dusk chases words off the page, my feet resting on a small stone wall we built together.

A flash just below my right foot.

I break from Harry Potter. A second scurrying critter rumbles about the flash. The flashing becomes frantic, several short blips in less than a few seconds. My eyes adjust--a spider dances around its prey.

I've never seen a lightning bug flash quickly like that, but then I've never seen one eaten by a spider either. A lightning bug makes a flash by adding a tiny bit of ATP to luceferin. In our mechanistic view of the world, not a bad worldview if you're in the business of conquering it, lightning bugs flash instinctively. They are not known to flash for defensive purposes.

I cannot know why this one flashed, but I do know that lightning bugs, at least this one, had a pattern distinct from its cherchez la femme mode when struggling with a spider.

I almost didn't try to "save" it--a good naturalist observes, does not interfere. The spider has as much a right to the meal as I do to mine. Death by spider is likely to be quicker than death by starvation if the critter could no longer fly.

I pulled the frenetically flashing bug out of the web--a white wisp of web stuck to its backside. I set it on a leaf of the birch with mixed feelings. It will die slowly because my imagination would not allow me to let the spider bite it.

As the critter struggled with its first pair of legs to grasp the edge of the leaf, I gently pulled back the stick. The spider silk stuck to my stick. The lightning bug scootched a few millimeters, no longer flashing, and stood still.

I watched a moment longer. The lightning bug opened up its beetley shell, opened its wings, and flew away.

A moment later, a lightning bug brushed my leg at the bottom of its "J". No way to know if it was the same one. And it really doesn't matter.


IV
Some Asian lightning bugs flash in unison. The lightning bugs in the Jersey area, at least the ones that make a J, are not known to do this (according to the scientists). Oh, occasionally they'll accidentally flash together a few seconds after the flash of a bright light, as though they were all resetting their bellies after seeing a god, but left alone, our fireflies are supposed to be the individualistic sorts.

The local critters must be illiterate--once or twice a dusk, they amuse themselves with synchronous flashing. (“Amuse” sounds like anthropomorphizing, of course--it’s an interesting word, comes from the French amuser, “to stupefy”--we’re most amused when our brains are buggy.) .


V
One poor fellow one evening couldn’t turn off his belly --he’d glow properly enough in his “J”, but still fizzled a bit as he looked for a response--doubt he could see much light beyond his perpetually lit self.

I muttered “padiddle.” .


VI
Lightning bugs are, obviously alive. They have a lot of ATP. They have a lot of luciferin and luciferase. We made lightning bug earrings, lightning bug drawings, we’d smear dying and dead lightning bugs over our faces and laugh and scream like the atavistic creatures we were, mock Indian face paint.


VII
I am a science teacher; I am not a scientist. A lot of folks are confused about what constitutes science. We want children to be amazed. You can purchase, via PayPal, a lightning bug “collection system.” You have a choice of sizes, and the handle glows in the dark. Imagine that! No doubt safer than punching holes in a half-rinsed mayonnaise jar.


Kids can study and be fascinated by all the little bugs found in the average back yard. Firefly lanterns allow children to watch the lighnting sicbugs light up. The bugs can be returned to nature where they were found after a day or two of enjoyment.
Plum Creek Marketing Entomology Products for Kids.


Another “experiment” suggests that kids catch lightning bugs in a jar for 5 minutes, record their observations, then let them go.

Took me 40 years to realize I learn a whole lot more doing nothing, feet up on a tiny stone wall next to my daughter’s puddle.
