Fearfully and wonderfully made

TED | Talks | David Bolinsky: Fantastic voyage inside a cell.

This is all just emergent behavior. It all just arose by chance, by the random combining of molecules over millions of years. It has no purpose. No desgner, no creator, no engineer set it in motion.

It.
Just.
Happened.



Sure. Tell me another funny story.

UPDATED - Open Phone Tests versus Just Knowing It

Will Richardson (Weblogg-ed) starts the day with a thought-provoking post about a student who sends text messages with his phone in his pocket.

---------------------------------- UPDATE Challenged by Barry(16) in the comments thread at Weblogg-ed, I re-read the article. It does not in fact say that Insoo was texting during a test, only that he was texting *in class*. That's the equivalent of passing notes, and hardly a character issue on the level of cheating on an exam. Further, the full article notes that he wants a new phone, the price of which is doing well on his exams. I've edited this post accordingly. Sorry to impugn your character, Insoo. -----------------------------------

This raises all sorts of interesting questions, being battered about in the comments thread and on Twitter. "If they can find the answer on the Net (including their personal learning network of friends and trusted strangers), is the question worth asking?" and so forth.

These are good and valuable questions to batter about. But...

As Charles says in the comments on Will's post, unless the networking is somehow helping Insoo grasp the mathematical concepts, then he isn't learning math. He may be learning something, but it isn't what was assigned. And what was assigned, we may assume, is something that is of value to society. Kids are always whining, "Do I really have to know this?" Cheating - of any form - is that whine put into action. We can argue about the relevancy of the curriculum. And we should listen to our students so we can make it relevant. But they don't get to decide what they need to learn and what they can slough off.

Second, there needs to be a recognition that sometimes you Just Need To Know It. If I'm on an airplane and the engine catches fire, I don't want the pilot texting his Personal Learning Network for a solution. I want him to "Execute the Engine Fire Checklist from memory with no prompting in less than 30 seconds with 100% accuracy." (Thank you, Mr. Mager!)

There's no question that we educators - with help from our madly-connected 21st-century students - need to devise relevant, authentic learning activities that leverage the power of these new communications tools and paradigms.

But it's fair for us to expect that they'll learn what we ask them to.

Black Friday

Game Somethingerother with #1 son. He can not only keep a secret, but feign surprise and delight. Besides, I needed an SME to keep from buying the wrong thing.

Then, across town to meet the wife and younger three at the sports store. A recument bike has been on the watch list, as we both need to reverse the caloric input/output ratio. Sale price expires in ten minutes. Smart clerk sized us up instantly. ("Not in shape, reasons to live, able to pay.") The box was waiting at the door when I walked in. My airplane will have fewer buttons and controls.

The all-you-can-eat pizza place was *right there*, so...



Hey. I had a salad, and only one "seconds" trip on the pizza. Progess, not perfection, right?

Finally, Sears and JCPs with the Daughters looking for a suitable Christmas dress. 12 tried. One settled on, after I said, "Oh, well. Looks like we struck out. No, we're not doing Macy's. Let's go home." It looks FINE. Really.

Then today, "Enchanted" and "Mr. Magorium's Wonder Emporium" followed by take-home pints from Hershey's Ice Cream.

All in all a very expensive weekend. And thank You, Big Guy, for making it possible. Feels okay to blow a bonus check on stuff for the fambly when you've already tithed on it. :-)

Digital Identities

"Glassbeed" has an interesting post about Kids and Digital Identities today.

I originally had several online IDs in order to keep professional, personal, and political commentary separate. I was concerned that prejudice about my personal views might color people's perceptions of my professional capabilities.

I quickly realized that it was far too much work to keep them totally separate. If someone takes a dim view of my professional contributions because they don't like the way I vote or worship, that's their problem.

Revealing comments

CNN.com - CNN Political Ticker Wrestler Ric Flair supporting Mike Huckabee «

Back many months ago I thought Huckabee had a shot at the national ticket. It's clear he's at best a second-tier candidate with regional appeal. (That *could* come in handy to balance Rudy, though.)

That "regional appeal" becomes more clear with his recent endorsements - Chuck Norris, Ted Nugent, and now a famous pro wrestler (whom I've never heard of, since the last time I watched "rasslin'" was when LBJ was President).

What's really revealing, though, is the reaction in the comments section at the CNN ticker site linked above. The hatred and bigotry that is expressed there is truly breathtaking.


But it isn't coming from the fans of Chuck, Ted, and the WWF.

New Technology Makes Aircraft More Crash-Resistant.

"The Delft University of Technology in the Netherlands will demonstrate how the application of Fault Tolerant Control can be used to keep damaged aircraft flying and improve their chances of being successfully recovered. "

It probably would not have helped in this case, though.

Amen, amen, and yea verily I say unto ye again, amen

Will Richardson at Weblogg-ed:

"At some point, I want one of the goals and outcomes for the students at my kids’ school system to be that they will graduate with the ability to build their own learning networks in effective, ethical and safe ways. But that will only happen when enough of the administrators and teachers understand that for themselves. Only then will they be able to help my kids add dots to their world maps in ways that teach them the power of networks in the ways we already know it."

A parable for teachers

From the email inbox:

Once there was a king who decided to set aside a special day to honor his greatest subject. When the big day arrived, a large gathering took place in the palace courtyard and four finalists were brought forward.

The first person was a wealthy philanthropist. This man was deserving of the king's honor because of his great humanitarian efforts. He had given much of his wealth to the poor, building orphanages, schools and hospitals throughout the land. The second was a celebrated physician. This outstanding doctor was deserving of honor for rendering his faithful and dedicated service to the sick for many years and discovering medicines that saved many lives. The third was a distinguished judge. He was noted for his wisdom, his fairness and his many a brilliant decision.

The last person presented before the king was an elderly woman. Her manner was quite humble, as was her dress. She hardly looked the part of someone who would be honored as the greatest subject in the kingdom. What chance could she possibly have, when compared to the other three, who had accomplished so very much?

The king was intrigued, to say the least and was somewhat puzzled by her presence. He asked who she was. Then the answer came: "Well, my king, do you see the philanthropist, the doctor, and the judge over here? She was their teacher!"

A human in the loop

Astronauts fix ripped solar wing

Sometimes, there's just no substitute for real "hands-on" problem-solving.

We have become masters of automation. Since the beginning of the Industrial Age, it's been all about faster and cheaper. Since people are slow and expensive (especially in space) that means getting people out of the loop. The more we can turn the work over to the machines, the more work can get done.

Until something goes worgn.

Machines are far better than people at performing pre-programmed tasks with precision. Star Wars - the 1977 pre-digital-effects original (a purist, I refuse to call it Episode IV) - could not have been made with human camera operators. But when the machines break down (as they always do), people must step in to fix it.

It's the same with learning. We can design all sorts of systems that automatically mold themselves to the student. We can create algorthims to diagnose and adapt to a specific "learning style", or anticipate a learner's probable errors and stand ready with remediation at an atomic level of detail.

But there will always come a point when a student steps off the design document.

It doesn't happen with every student, but a dollar gets you a doughnut it happens with every "automated instruction system" if it has enough users. Eventually, a student comes up with a question the designer didn't anticpate.

As the old pre-PC "Little Rascals"put it, "Now what, Buckwheat?"

But if we can put a human being back into the loop - someone who can interpret the lost look, the six-days-without-logging-in pattern, the forum post that is so clearly off-track - then we don't have to analyze the content to death.

Just build an additional component into the sysem: a teacher, a tutor, a peer mentor. (If you call them "a network of organic, analog feedback devices" you might even be able to get grant money to pay them.)

Willow Creek

A Shocking “Confession” from Willow Creek Community Church

Willow Creek has been at the forefront of the "seeker friendly" movement in the Evangelical Christian world. Offer lots of social services, upbeat music, stay away from the fire and brimstone, and you'll pack 'em in. Apparently they decided to do an internal study and found that while the church was growing, the people weren't.

Age of Wonders

In the film "Master and Commander," 19th-century British sea captain Jack Aubry is handed a wooden model of a new warship. He examines it carefully, noting its many innovative features. Finally he sets it down, saying, "What an age of wonders we live in."

If he had only known what was just over the horizon.
Since the Renaissance, every age has been an Age of Wonders, it seems. The colonies of the New World had limitless wealth. The Enlightenment promised a new dawn of scientific understanding. Steam would provide inexhaustible power. The telegraph allowed messages to be sent thousands of miles. Bell's telephone transmitted the human voice over a wire. In 1900, the Patent Office concluded that everything that could be invented, had been.

But more wonders were yet to come. As the new century dawned, Thomas Edison was working tirelessly to find a way to produce light with electricity. Henry Ford was realizing that an automobile could be built cheaply if the work was broken down to the smallest task. And in Ohio, two brothers were building a machine that could fly.

Within only fifty years, the electric light, the automobile, and the airplane had totally transformed society. By the end of World War II it was hard to imagine life without them.

Not long afterward, my father went to work for International Business Machines. He was initially set to work repairing price-calculating grocer's scales - the core of the business. Within a few years he was assigned to a new area called "data processing". Engineers had created an experimental calculating machine twice the size of anything previously attempted, with 40,000 characters of memory. It cost millions, and filled a large room.

In the mid-1950's, the most powerful computer in the world had 39k of memory.

Just a few decades later, Seymour Cray was building supercomputers. They were the size of refrigerators and orders of magnitude faster than anything else on the planet. They didn't have cooling fans - they had radiators. Researchers waited for months to get a few seconds of precious time on the mammoth machines.

Today, my kids' Playstation 2 has more processing power than any Cray ever had. For the price of lunch you can put 2 gigabytes of storage on a keychain: 20,000 of the room-sized machines my dad worked on, the size of a pack of gum. For less than $150, you can buy a 500 Gb hard drive. That's 200 billion pages of text - 33,000 college libraries. It's the size of a paperback book.

We're connected in ways Captain Aubrey could never have imagined. You can shoot video with a cell phone, upload it to YouTube, and it can instantly be viewed by millions of people, worldwide. If you have a question - any question - "just Google it" and you will likely get an answer in moments. If you like a song, you can buy it for a buck on iTunes (or steal it elsewhere). You can look up anything at all on Wikipedia, a reference thousands of times larger than the Encyclopedia Britannica - and change it yourself if you spot an error.

Welcome to the 21st century. Everything is different, now, isn't it?

Well, yes and no. True, people today seem to live in a cloud of constant sensory input, resulting in what one writer called, "continuous partial attention." Many of our students can't imagine living without computers, portable music players, game systems, and the like. Others have only heard about these wonders, and worry about what they're missing.

For those of us who teach (and who directly support the teachers), this is a huge challenge. Many of our students know far more than we do about the new tools and toys. Others struggle with basic skills most of us mastered years ago. Every semester faculty come to me and say, "Please get me set up with Blackboard. My students say I need to use it."

But in truth, the technology doesn't matter all that much. Regardless of the tools they use, people are still people. We all have the same basic human needs: for food and shelter, for security, for love and belonging, for esteem, for self-actualization. Under the iPod and Razr, behind the email or discussion board post, is a human being with the same fundamental needs as his or her great-great grandparents.

They just meet those needs in different ways, that's all. iTunes is not so very different than the traveling minstrel of Chaucer's time. It just has a larger repertoire.

A tool is merely a set of affordances and constraints - stuff it lets you do easily, and stuff it makes it hard to do. That applies to tools used for teaching, too. You can teach in the 3D simulated world of Second Life, where people can fly and a student may appear as an alien with an orange mohawk (ok, bad example - that can show up on campus, too). But you also can teach while sitting on a log and using your finger to draw in the dirt (hey - digital interactive multimedia!)

Drawing in the dirt is a quick and easy way to show something - to a person who's there with you. Teaching online lets you bring in all sorts of resources and frees the student from having to be in a certain place at a certain time - but you lose eye contact and facial expressions. Is that good? Is it bad?

Neither. It's just different.

You can't replicate a classroom online. Don't try. You can only work to replicate the results of the classroom. That's the most fun part of my job - helping faculty figure out how to use these new tools to get the same (or sometimes, better) results. Of course, the capabilities of the tools keep changing, and new tools keep appearing. (Some of them are so new we don't know how to really use them well.) We often feel like hamsters on a wheel that's spinning faster than we can run. But we keep up as best we can with what's going on "out there." We try new things. Sometimes they work better than we'd planned. Sometimes they crash and burn. We pick up the pieces, learn from the experience, and try, try again. We have to, if we want to prepare our students for the next Age of Wonders.

It's just over the horizon.

My ride on a B-17

Our little local airshow had never had a website. I made one for this year's show. (www.usaviationmuseum.com) It's gotten a fair amount of traffic, even after the show. (I concocted a photo contest to drive traffic after the show and reinforce the experience.)

During the show I work the flightline. (I get to tell pilots where to go, hee hee.) So Friday midday I'm out on the ramp, sweating and getting sore feet and a sunburn. (Hey, at least I don't have to pay for the priviledge.) Actually, it's a very nice day. A few clouds, a breeze, high 70s and severe clear. VERY nice day.

Around 2:20 the show boss called me over and asked, "What are you doing at 2:45 today?" I replied, "Whatever you want." (Of course.) Pointing to the fully restored B-17 Flying Fortress behind her, she said, "Be on that plane."

I replied, "Yes, ma'am!" (Of course.)

I signed the waiver, got my ID sticker. Went over to the flightline chief and told him that I'd been assigned to "special duty" until the '17 landed. He smiled a bit and nodded. He got a ride last year.

I waited, waited some more, then we were assembled and briefed by the flight engineer. "You have to stay seated until the wheels are up. Then you can move around at will, go up front to the bombardier's station, whatever, except for the tail and ball turret."

We boarded and strapped in. I was in the radio compartment. They opened up the "skylight" so we didn't bake.

There's a very loud, somewhat unpleasant screetchy sound, sort of like what you hear on an Airbus 320 when it's about to start its engines. I assume it's an hydraulic pump.

I'm on the starboard side, with a glimpse out a tiny window. I can see a LOT of rivets on the right wing and the #3 engine (inboard right side) That's the one that starts first. The prop starts turning. 14 blades, then a cough, grumble, roar. #4 turns, starts. #1, #2. All four engines are now idling, each consuming 20 gallons per hour of $5/gal avgas. A penny per second, just to sit there with the motors running.

The whole airframe shakes with suppressed power. This is no Walter Mitty pocketa-pocketa fantasy. This is a serious machine built for a serious purpose - to defeat a serious and determined enemy.

The sound increases and we start to move. The brakes squeal. From my seat I can look forward and see the ground through the open bomb bay doors. More loud sound, and the bomb bay doors close.

We taxi for a long time. The airfield has no parallel taxiway, so you back-taxi down the active runway to a turnaround at the end. No control tower, and the airport is open, so it's up to the pilots in the pattern to talk to each other in order to avoid... unpleasantness. You can imagine the radio calls: "Lost Nation traffic, Cessna Three Four Bravo five miles south, inbound for Two Eight, Lost Nation." "Three Four Bravo, be advised, a B-17 is back-taxiing on Two Eight." "Three Four Bravo, we'll extend."

We complete the slow turn - the taxiway is barely wider than the our gear - and take the active runway. The engines rev up to takeoff power.

The airplane had been quivering at idle and taxiing, like a dog eager for the owner to loose the leash. Now the leash is off, and the animal leaps forward. The acceleration isn't the shove-you-back-in-your-seat thrill of a sports car. It's not the relentless, smooth press of a commercial jet meeting a schedule.

It's more *purposeful* somehow. We have a war to win, I think. Thousands of people back home have labored to build this machine so that we can use it stop Hitler and end this damned war. I don't imagine what it must be like to feel that, I actually feel it. It's a fleeting moment, but a real and powerful one.

We lift off easily at our light weight, and I think of what it must have been like to know you were thousands of pounds over gross, willing the wing to lift, not being able to see forward but knowing that this. takeoff. is. taking. a. really. long. time...

We climb out straight ahead. I can see out the sliver of window a local landmark near my house. We must be nearly directly overhead, at less than a thousand feet. A phone call while waiting to start engines had alerted the home crew. They were outside and waving as we flew overhead, they tell me later. I might have seen them if the bomb bay doors had been open.

The gear is up, and we get the word (ok, a hand wave and a nod) that we can unstrap and move around.

I realize quickly (with much gratitude) that a pudgy out-of-shape 45-year-old has about the same dimensions and flexibility as a skinny nineteen-year old in a sheepskin flight suit. We squeeze past each other, grin madly, take turns at the waist guns. badda-baada-baddabadda! ("Yah, Sven, dere vas Fokkers above, Fokkers below, Fokkers to da left and right. And alla dem fokkers vas Messerschmits!").

Yeah, funny. But holding the waist gun, looking out the window, hunched over peering through a ring sight... I've seen the films. "Dem Messerchmits" are small targets, moving fast, and they are trying to kill you. The '17's skin is thin. The helmet and flak jacket don't cover everthing.

The moment passes.

This was a media flight. A local reporter was on board, with a camera ship flying in formation to get some shots with downtown or the lake in the background.

Also in formation, a pair of P-51 scale replicas. 3/4 the size of the real thing, and 1/20 the cost.

The crew had removed the "sunroof" - the large clear panel over the radio room. We could (carefully) look out this large opening and have a perfectly clear view of the tail and the sky all around.

I take off my hat, hold onto my glasses, and look back at the tail and the lakeshore below. Holding station at five o'clock high and seven o'clock high are a pair of P-51s.

I know it's 2007. I know those are scale replicas, not the real thing. But for some reason, standing in a B-17, looking out at a pair of P-51s, I feel... protected.

We pass over the lakefront downtown airport, LOW, and hit the airshow smoke on #2. Someone downtown calls 911 thinking we're on fire.

We climb and turn, and I have a magnificent view of downtown and the lakeshore out the open hatch. I make my way forward, squeezing through the bomb bay catwalk to the flight deck. The three-man crew is all cool professionalism in their flight suits. There's a GPS moving map attached to the panel. I try to ignore it.

I squeeze down between the pilots' seats to the nose compartment. I imagine peering through those little windows on the side, trying to spot the enemy fighters. I imagine deadly black flowers of flak blossoming outside the big clear bubble at the very front. Nothing you can do but hope they miss. Bombardiers and navigators suffered the highest casualty rates.

I make my way back to the engineer's station - we're minutes from landing, now. But I pop up into the top turret one more time, look towards the shore, and I can see my house. I wave, knowing the kids can't see me.

We take our seats and strap in for landing. I'm wedged into the radio compartment again. A long, low final approach - the airport neighbors who hate airplanes must be LOVING this! - we cross the threshold, three quick screetches and we're rolling.

Taxing in and shutting down is anticlimactic. As the props stop, I once again think of the kids, now old men, who took this airplane into harm's way. They had no idea that their sacrifice would ensure that my kids would grow up in freedom. They just wanted to get the job done.

I look at the guy across from me and say, "Twenty-four more, and we can go home."

The Ratings Always Drop Twice

I'm not normally a big fan of noir, but this satire from Iowqahawk is rich.

Note - if you don't get the inside jokes, you obviously don't read the center-right blogs. He left out a few folks, but the "Jimmy Fargo" and "Dragon Lady" references are classic.
