I just asked Christopher if he thought this joke was funny:
He said, "No."
Then he said, "I just put down Who cares? for everything."
I love this age.

ItTakesChops 07 Jul 2005 - 22:09 CatherineJohnson
It takes chops to solve this when you're eleven:
Two cars leave simultaneously at 9 a.m. heading toward one another from different cities that are 210 km apart. The average speed of one car is 50 km/h while the other car averages 70 km/h. Come up with an appropriate question and answer it.
This problem appears on page 5, 'Review,' of Mathematics 6: an award-winning textbook from Russia, by Enn Nurk and Aksel Telgmaa.
The 6 in the title stands for 6th grade.

update: OK, I solved it.
But I couldn't think of a bar model.

On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

EarthboxDay 21 Nov 2005 - 04:14 CatherineJohnson
Since it's my birthday, and since I get to do what I want on my birthday, more or less, and since I DON'T HAVE A CAT TO BLOG ABOUT, I am choosing to blog about EarthBoxes.
EarthBoxes are even better than Russian Math
To prove this to KTM readers, I am going to enlist Christopher in a measuring task.
No!
Not a task!
An investigation!
WE ARE GOING TO PERFORM A MEASURING INVESTIGATION!
WE ARE GOING TO COLLECT DATA!
AND WE ARE GOING TO USE A RULER TO DO IT!
OK, now we have resistance and rudeness.
'No!'
'Not today!'
'Then I'm not doing a lesson!'
Funny how the kids in the Math TRAILBLAZERS PLAYLETS never seem to react this way when a grownup suggests that they collect data in order to solve a problem.
Alright, while the moaning and groaning continues in the background, I will locate:
[pause]
Question. Why do we never, ever, ever put rulers away in this house?
[pause]
Rulers located.
Anyone care to lay odds on whether the tape measure is living in its designated spot in the kitchen junk drawer?
[pause]
Yes. Tape measure in its designated spot, along with, apparently, every other smaller-than-8-inch item we have acquired in the past 12 months or however long it's been since the last time I went on a junk-drawer cleaning jag.
Time to start tossing.
Now Christopher is eating lunch.
At 2:31 pm.
So it's looking good for the Bad Mother of the Month Award in July, too!
Back shortly.
In the meantime, this is an EarthBox.
EarthBox Investigation
Christopher and I used a ruler to measure the basil plant planted in the ground, and a tape measure to measure the basil plant planted in our EarthBox.
The two plants came from the same nursery, on the same day, and were the same size when we planted them. The EarthBox is directly next to the patch of earth where the other basil plant is planted, and the two plants get the same amount of sun, rain, etc.
The basil plant in the earth is scrawny, not too healthy looking, and stands 10 1/2" tall.
The basil plant in the EarthBox is a bush.
It is 14 1/2" inches tall, and is so huge and fleshed out that Ed is going to cut it back because he's afraid it's blocking the sun for the green bean plants that are also growing in the same EarthBox.
Not that the green bean plants look like they need any help. They're bushes, too.
The tomato plants in the tomato EarthBox look like the stalk in Jack and the Beanstalk, and we've got corn stalks barrelling up-up-up out of yet another.
I just ordered more EarthBoxes.
Here is a web site that tells you how to make a homemade EarthBox.
What I want to know now is how to duplicate the EarthBox technology for indoor plants in small pots.
update
I was just cruising the EarthBox web site.
Here's a line from a satisfied customer:
"Quite a new wave of gardening. We are having so much fun with our 'MONSTER' tomato plants.”
Mary M. Forestdale, MO.
It's true.
Our EarthBox plants look like the kind of thing you see in those Fantastic Island—type movies, where the actors shipwreck on an Island Time Forgot and every living thing they find is 10 times bigger than it's supposed to be.
It's only July 1 and I'm already wondering how on earth I'm going to use all the basil I've got. (I'm pretty sure I remember where my gazpacho recipe is, so that's a plus.)
Oh wait.
Gazpacho takes fresh parsley.
Not basil.
So I have to find my pizza recipe.
It's probably in the same place we left the rulers.
Well, thank heavens we didn't grow cucumbers. There's another customer quoted on the site shown standing on a ladder next to a cucumber plant that's about 8 feet tall, maybe taller. He says that from June 20 to August 18 he picked 105 cucumbers. The biggest one was 16" long. That's just gross.
update July 24, 2005
Green bean plants kaput, basil plants victorious.
Green beans & basil don't mix?

TheQuoteGarden 05 Jul 2005 - 17:14 CarolynJohnston
While looking up the genesis of a quote about statistics this evening (AnneDwyer quoted it: "torture numbers, and they'll confess to anything"; the quote was originally by Gregg Easterbrook), I came across some fun pages: The Quote Garden for statistics and mathematics.
Here are some of the quotes I especially liked. I don't know what this collection says about me, other than that I'm possibly a very silly person.
I notice an interesting thing about the statistics quotes vs. the math quotes: the math quotes tend to be admiring, and the statistics quotes tend to be wry and distrustful. The practice of lying with statistics seems to go back a long way.
I've dealt with numbers all my life, of course, and after a while you begin to feel that each number has a personality of its own. A twelve is very different from a thirteen, for example. Twelve is upright, conscientious, intelligent, whereas thirteen is a loner, a shady character who won't think twice about breaking the law to get what he wants. Eleven is tough, an outdoorsman who likes tramping through woods and scaling mountains; ten is rather simpleminded, a bland figure who always does what he's told; nine is deep and mystical, a Buddha of contemplation.... ~Paul Auster, The Music of Chance
There was a young man from Trinity,
Who solved the square root of infinity.
While counting the digits,
He was seized by the fidgets,
Dropped science, and took up divinity.
~Author Unknown
How many times can you subtract 7 from 83, and what is left afterwards? You can subtract it as many times as you want, and it leaves 76 every time. ~Author Unknown
The human mind has never invented a labor-saving machine equal to algebra. ~Author Unknown
Statistics are like bikinis. What they reveal is suggestive, but what they conceal is vital. ~Aaron Levenstein
98% of all statistics are made up. ~Author Unknown
Lottery: A tax on people who are bad at math. ~Author Unknown

Christopher at breakfast this morning:
What if there's a math boot camp?
Then it'd be like, Come on, maggot! Drop and give me 20 multiplication problems!
Come on! Go faster! Go faster!
For that sluggish work you're gonna have to do 20 more division problems and scrub the toilets for a week! While doing mental math!
Do I make that clear?'

MarketingMathProblems 11 Jul 2005 - 22:45 CarolynJohnston
My stepson Colin is living with us for the summer. While Ben works on his 6th grade math, Colin is working on his SAT (new SAT!) preparation, and both of them are beefing up their vocabularies.
Colin is very interested in business, and yesterday when we were driving somewhere, he commented that the phrase math problems is bad marketing.
"Why?" Bernie asked.
"Because the term problem gives the whole thing a negative spin," he said.
"Nobody's allowed to say problem anymore anyway," I said. "People don't have problems, they have issues. Let's call them math issues," I weighed in, but I was roundly ignored.
"People call them exercises, typically," said Bernie.
"But that's got negative spin, too," Colin said.
"You're right," I said, "the word exercise makes it sound as though it's tedious and tiring."
"Really, they should be called puzzles," Bernie said.
It makes perfect sense to me to start calling them puzzles, actually. Every math problem is a little puzzle, in both senses; they are puzzling, and each one is a little self-contained game or toy. When you enjoy doing math, it's because you're getting into the puzzle aspect of it.
So I think we should start calling them 'puzzles'. Math puzzles, word puzzles. It sounds good.
Now who do I talk to about getting this changed?
HecksLibrary 11 Jul 2005 - 16:47 CatherineJohnson
Call me crazy, but I don't think this would be a whole lot more fun if every book said Math Puzzles Galore on the spine.....
Of course, I could be wrong.
Either one would be better than a wall-full of books on long division.

KleinBottleHat 12 Jul 2005 - 18:09 CarolynJohnston
If Catherine can blog about crocheting hyperbolic space, then I can blog about some unique geek knitwear: Klein Bottle Hats.
A Klein Bottle is a two-dimensional surface that is something like a twisted-up torus (a torus is the surface of a doughnut). It can't exist in 3 dimensions without intersecting itself, but it can be imbedded in 4 dimensions. If you slice open a Klein Bottle, you get a Moebius Strip.
Since this hat does exist in 3 dimensions, it's not a genuine Klein Bottle Hat, but it comes pretty close.
Here is a picture of Cliff Stoll (an astronomer and computer scientist) wearing a Klein Bottle Hat:
You can get a matching Moebius Strip scarf to go with it.

As it happens, I am an Experienced Knitter.
Hey look!
They have the directions for Clifford's Knitted Klein hat over at Wolfram's Mathworld!

NerdReport 24 Dec 2005 - 01:15 CatherineJohnson
Through my usual circuitous route (ktm to brightMystery to nerdtests.com) I stumbled onto a web site with a test for nerds.
My score: 50%
This is a Francis Galton moment (more on which later, or see BlookiHelpWanted & scroll down.)
I am always, in every single quiz, poll, or test I take, dead center.
And I mean…..DEAD……CENTER.
It simply never fails.
A couple of years ago I took a famous Are You A Republican Or a Democrat? test and found out I was Colin Powell.
Yes, I know Colin Powell works for the Republicans, but in this particular test he was DEAD CENTER.
I always tell Ed, and this is something he really enjoys hearing 5, 6, 10, or 20 times a month, Forget it, don’t even bother arguing with me about who's going to win the election, or whether BATTLESTAR GALACTICA just turned into WEST WING, for I Am Everywoman.
I am, too.
If I think or like or am keenly interested in X, that means everyone else is thinking or liking or keenly interested in X, too, or at least enough folks are thinking, liking or keenly interested in X that X is going to be everywhere you look until I stop thinking, liking, and/or being keenly interested in X and move on.
Still, even though I have an unbroken string of Dead Center scores on all manner of pop psych quizzes and tests, I did not expect to score Dead Center on a test for nerds.
But I did.
I am a nerd bellwether.

FlowChart 04 Sep 2006 - 21:36 CatherineJohnson
Yes, it's a Constructivist Flow Chart!

Actually, this web site is worth taking a look at for a quick overview of educational psychology. On the basis of very rapid skimming, I'd say that the author, Richard Hall, the associate Dean for Research, School of Management and Information Systems at the University of Missouri Rolla, seems to have some horse sense.
Topics covered:
active learning
assessment
behaviorist theory
constructivist theory
information processing theory
learning in groups
learning strategies
learning styles
metacognition
education, hypermedia, and the world wide web
update: definitely worth reading
I've just read the constructivist page closely, and this is quite a nice summary. When you put all 10 of these pages together, this is probably the most useful short, concise comparison-and-contrast discussion of contemporary ed psych topics I've come across.
I'm going to read all of them.

WichitaBoyOnMath 31 Jul 2005 - 22:15 CatherineJohnson
We have an embarrassment of riches! At least 2 great comments from WichitaBoy, and Ed sat down and wrote out his constructivism-as-psychoanalysis thoughts, too.
Here's one of WichitaBoy's observations:
"Writing is organizing." Now there's a great thought I can take to the bank.
Here's one back for you: professional mathematics is organizing. You have vague thoughts, you notice a vague pattern, and you try to organize your thoughts, to nail down the pattern, to really clarify what's going on beneath the hood. When you've nailed it completely, when you understand with perfect perspicacity the essence of the pattern, then you've got a proof of a new theorem. If you've really organized it, you've got a theorem that goes in the "Book of God".
There's this, too, in response to my saying that what is brilliant about Saxon Math--the structure--is largely invisible:
Read Confucius or Socrates. The ideal teacher should be able to fade into the background like the Cheshire cat. And so with the ideal textbook.

BackpackInjuries 21 Aug 2005 - 17:20 CatherineJohnson
In the TIMES today, an article about acute backpack injuries. We're in luck, because the American Academy of Pediatrics has done a study:
Surprisingly, it wasn't the weight of the backpacks that was the most common cause of injuries; it was tripping over the backpack, which occurred in 28 percent of the time. Getting hit by the backpack caused 13 percent of the injuries.
Getting hit?
"The 'nonstandard' use of the backpack (tripping, hitting, etc.) resulted in 77 percent of all backpack injuries that required an emergency room visit," the study noted. Therefore, training students to put their backpacks in a safe place and not to use them as weapons against another person would eliminate many backpack-related injuries.
Training your kid to duck doesn't sound like a bad idea, either.
update
Have I mentioned how much I'm looking forward to middle school?
update update
Charles left this comment:
There is an influential middle school movement (NMSA, The National Forum to Accelerate Middle-Grades Reform) out there that treats middle schools more like a psychiatric ward than a place of learning. It has its own weird jargon, things like "transescents". "Brain periodization" is one of my favorites. (This movement distinguishes between middle schools [good] and junior high schools [bad, too academic]).
When I went through ed school I took courses (for middle grades endorsement purposes) that focused on the middle schools. The only textbook we used in one course (a movement book) told us in one chapter that teaching academic subjects makes one complicit in the great evils of the 20th century and past centuries like genocide, the Holocaust, slavery and much more. (I can provide specifics).
You are probably familiar with Yecke's book on middle schools, The War Against Excellence: The Rising Tide of Mediocrity in America's Middle Schools.
See Reedy's Amazon review in particular:
To justify the dumbing-down of the curriculum, the social engineers, starting in 1978, made use of a loony, mad scientist theory called "brain periodization." This first cousin of phrenology claims that "brain growth reaches a plateau around the ages of 12-14 at which time ?the brain virtually ceases to grow.?" Hence during this "learning plateau period" it was considered dangerous to introduce "new and challenging material" which could result in "negative neural networks to dissipate the energy of the [challenging] inputs." The NMSA "formally endorsed" this theory in 1981, and the theory reigned supreme for ten years. Even after it was admitted in 1993 that "there is no supporting evidence" for it, its influence lingered on and lingers on even today, sustained by ideology but not by science. Parents who complain of lack of rigor, low expectations, and student boredom are considered "difficult," and papers are delivered at conferences advising teachers how to deal with them.
nix on 'the first 3 years'
This idea is dead wrong. If you need evidence, go read the Frontline interview with Jay Giedd.
pull quote:
Giedd is a neuroscientist at the National Institute of Mental Health. Recently, he spearheaded research showing for the first time that there is a wave of growth and change in the adolescent brain. He believes that what teens do during their adolescent years -- whether it's playing sports or playing video games -- can affect how their brains develop.
Also, here's a link to an online newsletter write-up I did years ago on this subject: Doomed before Kindergarten? There's also a Q & A with Jerome Bruer, author of The Myth of the First Three Years: A New Understanding of Early Brain Development and Lifelong Learning that's terrifically helpful.
yet another National Forum!
Here we go.
Charles's aforementioned National Forum to Accelerate Middle Grades Reform!
The National Kitchen Table Math Forum
So now I'm thinking we need a name change around here.
Just so people know we're serious.

DanesBeatBraQuota 23 Aug 2005 - 13:44 CatherineJohnson
Danes beat bra quota but import crisis deepens
For Claus Walther Jensen, getting his hands on bras for Christmas is one of the most important aspects of running Change, a Danish lingerie chain.
That's why the director went so far as to borrow a helicopter yesterday morning to secure one of the last European Union import licenses for bras.
"We had 45,000 panties in Christmas colours but their 45,000 matching bras were trapped in a warehourse," said a relieved Mr. Walther Jensen after his helicopter dash. "Other companies are suffering. I've got my goods in but I don't want to win market share this way."
No one does droll like the Brits.
Actually, no one besides the Brits does droll at all.

SchozLearning 25 Aug 2005 - 16:31 CarolynJohnston
Instructivist cracks me up.
Today he's found that a new learning modality has been added to the expanding list of learning styles: olfactory.
He makes fun of it, of course, but he's too quick to belittle the idea. I think there's something to it; in fact, I think I am an olfactory learner myself. As such, I can see real possibilities for really getting through to kids who are olfactory learners. They are even in line with letting the content determine the modality. Here are some ideas:
1. Science classes in which olfactory learners learn about putrefaction by getting a solid whiff of an uncorked test tube of a bit of rotting road kill.
2. Aiding rote memorization tasks, such as geography drill, by associating each country with a special smell. Examples: Italy - tomato sauce, Switzerland - chocolate, Romania- the way your grandma who uses Oil of Olay smells, and so forth. Think about it. Everyone knows smells are deeply linked with memory; we could potentially ensure that every kid who ever smells watermelon from now on involuntarily remembers all the states that the Mississippi River passes through on its way to the Gulf of Mexico.
3. Health class experiments in which half the class abstains from bathing for a couple of weeks (the others continue bathing as experimental controls).
4. 'Olfactory writing' assignments (with report titles such as "An imagined olfactory tour through the Amazon rainforest" -- a theme which has a nice tie-in with the Naturalist Intelligence).
5. Scratch-n-sniff history textbooks.
6. In a purely behavioral vein -- waking up inattentive olfactory learners with sudden blasts of smelling salts. This would have worked for me, I feel sure.
I am sure there are lots of other possibilities. Please add your ideas.
NewMathByTomLehrer 04 Sep 2005 - 15:47 CarolynJohnston
In case there's anyone here that still thinks that what's going on now with constructivist math is any different from what's been going on for decades, here's the lyrics to Tom Lehrer's song "New Math", written in... um... the 1960s.
{Spoken}
You can't take three from two
Two is less than three
So you look at the four in the tens place
Now that's really four tens
So you make it three tens
Regroup, and you change a ten to ten ones
And you add them to the two and get twelve
And you take away three, that's nine
Is that clear?
Now instead of four in the tens place
You've got three
'Cause you added one
That is to say, ten, to the two
But you can't take seven from three
So you look in the hundreds place
From the three you then use one
To make ten tens
And you know why four plus minus one
Plus ten is fourteen minus one
'Cause addition is commutative, right?
And so you've got thirteen tens
And you take away seven
And that leaves five
Well, six actually
But the idea is the important thing
Now go back to the hundreds place
And you're left with two
And you take away one from two
And that leaves
Everybody get one?
Not bad for the first day
{Refrain}
Hooray for new math
New-hoo-hoo-math
It won't do you a bit of good to review math
It's so simple
So very simple
That only a child can do it
Now actually, that is not the answer that I had in mind because the book that I got this problem out of wants you to do it in base eight. But don't panic. Base eight is just like base ten really, if you're missing two fingers. Shall we have a go at it? Hang on...
{Spoken}
You can't take three from two
Two is less than three
So you look at the four in the eights place
Now that's really four eights
So you make it three eights
Regroup, and you change an eight to eight ones
And you add them to the two
And you get one-two base eight
Which is ten base ten
And you take away three, that's seven
OK?
Now instead of four in the eights place
You've got three
'Cause you added one
That is to say, eight, to the two
But you can't take seven from three
So you look at the sixty-fours
"Sixty-four? How did sixty-four get into it?" I hear you cry. Well, sixty-four is eight squared, don't you see? Well, you ask a silly question, and you get a silly answer.
From the three you then use one
To make eight eights
And you add those eights to the three
And you get one-three base eight
Or, in other words
In base ten you have eleven
And you take away seven
And seven from eleven is four
Now go back to the sixty-fours
And you're left with two
And you take away one from two
And that leaves
Now, let's not always see the same hands. One, that's right. Whoever got that one can stay after class and clean the erasers.
Hooray for new math
{Refrain}
Come back tomorrow night, we're gonna do fractions.
Go here to hear the song. It's a riot.

What ironclad rule have I just violated?
(I'm betting on Doug for this one.)

The answer is here.
OK, I should have read the Comments first
As predicted, Doug takes this one:
"To say that the animation was distracting to these users would be an understatement. It was downright irritating. ...
"... During at least one of our tests, while trying to answer a question about the lowest fares to England, an animated ad appeared with the text of "Lowest Fares To London." Not only did the user not click on the ad, he swore he never saw it. Somehow, the user had "masked" out the animation."
The language here is interesting: 'the user had masked out the animation.
My understanding of frontal lobe function—and I'm not entirely confident of this, so take it with a grain of salt—is that it requires energy to block out distractions.
'Ignoring' something is an action.

from Harry Hutton today (f-bomb alert):
Killer Fact! Arizona is the stupidest state in the whole United States—quite an achievement given what the rest of the country is like—yet last year their economy grew by 7.1%, second only to Nevada, the fourth stupidest place. Florida, California, Arkansas and Idaho were also in the top quintile for growth, yet near the bottom for education. In the tiger economies of the 21st century the workers will barely be able to count their own ears. Meanwhile the Germans, who tried to cheat by having an educated workforce, lurch from crisis to crisis.
A glance at the Sunday Times Rich List tells the same story:
Richard Branson (£2.6 billion)—left school at 15
Bernie Ecclestone (£2.3 billion)—left school at 16
Eddie Healey, kitchens supremo (£1.3 billion)—left school at 16.
Duke of Westminster (£5 billion)—couldn't even get into agricultural college
Lord Cadogan (£1.5 billion)—raised by bears
Philip Green, who left school at 15, last week awarded himself a £1.2 billion dividend. But is he happy? As a matter of fact, he is. He's [effing] delirious.
As far as I can tell, Lord Sainsbury is the only educated person in the top twenty, not counting foreigners. Whereas I, with my Oxbridge degree (Women's Studies with Forestry), have no money at all. See what I mean?

But not everyone hates math. About 25 percent of those surveyed said it was their favorite subject, which is about the same number who chose English and history. Slightly less chose science. Of course, math is one of those subjects that appeals to people who like clear cut answers. One plus one is two. Those who find such a black and white process overwhelming, prefer subjects that have a bit of gray and allow for interpretation and debate.

Back when Carolyn and I first started writing this BLOOKI, I would occasionally come across one of these Toothpaste for Dinner cartoons.
I thought they were weird & creepy.
But just lately I've been running across Toothpaste for Dinner cartoons and thinking, 'Yes. My thoughts, exactly.'
I wonder if that means something.

OK, I've just had one glass of Life-Extending red wine with my friend Kris.
Which means I'm sure I must be misreading this article in the TIMES, which seems to be about a drug-dealing geometer:
DRUG dealing has not done James Robbins much good, unless you consider his current 6-to-12-year stretch in New York prisons a sign of success. On the possibility that he may want to try a new line of work when he gets out, here's an unsolicited thought:
Apply to the city's Department of Education. It might want someone with experience to talk to students about the importance of learning mathematics. Mr. Robbins, whose specialty is the Pythagorean theorem, could be especially helpful in this regard.
Maybe I really am living in a parallel universe.

One of our friends in L.A., who sent her now-college-age son to a famous progressive school, told me the kids tested in the 19th percentile for math achievement at the end of 5th grade. When parents complained, school personnel said they didn't believe in standardized tests.
She also refused to let her son play video games at any time during his childhood. That takes spunk.
Now she thinks expertise in video games might have helped with math, or at least with the 'spatial substrate' of math ability....
All in all, a classic case of a parent being fooled and foiled at every turn.
Yup. Been there. Done that.
Still doing it.
rich people are different from you and me
This particular school has a large body of very wealthy parents. Spielberg-level wealth.
Many of those parents loved the school for its 'creativity.' They weren't worried about the 19th percentile, because they were having their children taught real math by the Beverly Hills High School math teacher after school every day, for a fee of $150/hour.
This is 10 years ago, remember.

from Tracy
The formulation my family uses is:
Unconscious Incompetence Or don't know what you don't know. E.g. when you start skiing you're falling all over the place and don't know why.
Conscious Incompetence You know that the reason you're falling over all the time is that your skis keep crossing, but that knowledge doesn't stop it happening.
Conscious Competence Your skis don't cross but you have to concentrate on it.
Unconscious Competence You don't think about skiing. You think "Hmmm, I'm going to ski over to that point there" and then you do.
I love this.
I look forward to one day achieving unconscious competence in.....um.....ANYTHING AT ALL.
Ever since Christopher starting flunking math, I've been IMMERSED in UNCONSCIOUS INCOMPETENCE.
I'm falling all over the place.
I don't know why.
I don't like it.

Last night Christopher asked me where his KUMON sheets were.
When I rapidly located his KUMON box on my desk (not where it belongs) and pulled out the sheets, he said, 'How'd you get so organized?'
You probably have to have a specific learning disability in organizational skills to think I'm an organized person.

btw, I do need paper.
I started having a terrible time with my KUMON worksheets just last week....
I discovered 2 things:
a) I need strong light
b) I NEED LINED PAPER
The problems I'm doing now are fairly complicated 3-fraction operations, sometimes with decimals thrown in, and all four operations on the same worksheet & often within the same calculation.
To do such problems rapidly and accurately I need strong light and lined paper.
I'm finding that I'm losing track of where I am and what I just did to what (especially since these problems always involve canceling).....
Temple told me that fully 1/3 of the brain is committed to vision & visual processing, a factoid I saw confirmed recently (though I'm not going to dredge up a source right now).
That tells me that if our kids are doing complicated math problems on unlined paper.....they shouldn't be doing complicated math problems on unlined paper. You're eating up a whole lot of brain resources trying to keep track of fraction computations on unlined paper. (Apparently the NY state tests are all given on unlined paper, and the kids aren't allowed to use any paper but the test paper. Another smart edu-move!)
Anyway, from now on I'm going to try to always take a look at the visual environment whenever Christopher or Andrew are having problems doing math (or any other academic subject).

From time to time TWiki won't let me create a post.
That happens, it seems, because TWiki has banned certain words.
Thus far those words are:
I can't include the words 'pornography' or 'socialist' in a post title.
Interesting.

now that's synchronicity!
The reason I attempted, this morning, to write a post with 'socialist' in the title was my latest synchronicity event.
I hadn't read kausfiles in awhile, and when I logged in this morning I found this:
Socialist for a Day: I tempted fate by returning to the allegedly friendly Culver City branch of the state DMV, this time at 5:00, the end of the work day when the bureaucrats are frazzled. I was confronted at the information desk by a large, surly-seeeming woman who promptly ... smiled a large, beautiful smile and asked "How can I help you." Then she helped me. ... Scary! ... A few minutes later I was forced to take the bus from my mother's house to my mechanic's garage, in a relatively gritty section of Santa Monica. At rush hour. In L.A! The bus ... well, it arrived within seconds and the driver charged through traffic like a lancer. I got across town in 10 minutes. ... I'll snap out of it, but at the moment I only want to be assisted by unionized civil servants. 12:55 A.M.
oops — Christopher is sick — must pick him up — back shortly with MORE SYNCHRONICITY

I'm back.
synchronicity report
So Christopher and I were having dinner with Kris & her two kids last night.
We were swapping Mom war stories, and Kris had one I'd never heard before.
She said she woke up the day before in an ERRANDS MUST BE DONE NOW frame of mind, so she rolled out of bed and blew out of the house, bypassing shower, makeup, hair, and a plausible set of clothes. She just threw on whatever was there and took off.
She drove to the DMV.
She drove to the DMV, and.....she was back out again in 5 minutes.
She went in, took her number, the clerk called her number, she handed the clerk her paperwork, and that was it. She was done.
Which meant she now had no alternative but to proceed to ERRAND NUMBER TWO, a trip to a business up north that's owned by SOMEONE SHE WENT TO HIGH SCHOOL WITH & HADN'T SEEN IN 5 YEARS.
Needless to say, if you're going to see someone you went to high school with & haven't seen in 5 years, you want this to take place on a day where you didn't bypass shower, makeup, hair, and wardrobe.
Twenty-four hours later, she was still getting over the shock.
what are the odds?
Until last night, I had never in my entire adult life heard a story about getting in and out of the DMV in 5 minutes.
Then I wake up this morning, decide to check in with kausfiles for the first time in months, and....there's another story about getting in and out of the DMV in 5 minutes.
I have no idea what this means.
Synchronicity and the Gears/Wheels of Time
So I checked in with the folks at Synchronicity and the Gears/Wheels of Time, who have this to say:
Synchronicities are people, places or events that your soul attracts into your life - to help you evolve or to place emphasis on something going on in your life....Each day your life will become filled with meaningful coincidences - synchronicities - that you have attracted - or created in the grid of your experiences in the physical.
There are no accidents - just synchroncity wheels - the gears of time - the wheels of time - the wheel of karma - wheels within wheels - the alchemy of creation - the Philosopher's Stone - Sacred Geometry=SG=StarGate - evolution of consciousness....
Do be careful. Not all synchronicities are positive.
That clarifies things.

severely off-topic
This story is very far off topic, and is fairly upsetting, or at a minimum unsettling. So don't read if the first lines tell you not to.
I'm posting it only because it's my favorite story of synchronicity.
From the September 24, 2001 issue of THE NEW YORKER, the issue with the all-black cover.
Katherine Ilachinski is a seventy-year-old architect. As a girl, she survived the German bombing of Belgrade. On Tuesday morning, she was in her office on the ninety-first floor of Two World Trade Center, working on a sketch for changes to an electrical substation at the Hoboken terminal of New Jersey Transit. The first jet hit One World Trade just above the level of her office window
"There was an explosion, and a fireball went along the side of my building where I was sitting," she recalled. "It was so hot. It was like being in a boiler. I had to get out of my office. I went into an interior passage, then into the main corridor, to the elevators. You know, I was in the building in 1993, when we were bombed, and that time my instincts were completely different. Then, I closed my office. This time, I just wanted to get out of the building. Some people were taking the stairs. But I thought, I'm too old to walk so far down. Our elevators go to the lobby on seventy-eight. So I took the elevator to seventy-eight.
"The lobby there was mobbed, everybody trying to get in the elevators to the ground. I saw a guy who worked for me, Anthony—Anthony Portillo," Mrs. Ilachinski said. Her voice trembled. "He's a CAD operator—that's computer-aided design. I told Anthony, 'Let's take the elevator to forty-four.' It was still too high for me to walk, but the elevators to the ground were so crowded. There was no air. And I know what happens if the elevator gets stuck. You are doomed. But Anthony said, 'No, Katy.' He wanted to take the elevator all the way down. I didn't trust it. So I took the elevator to the forty-fourth floor. That elevator was relatively empty.
"But the scene in the lobby on forty-four was a repetition of seventy-eight. It was just mobbed. People all the way from east to west. Most of them waiting for the elevator to the ground. That was when I decided to try to walk, and something just propelled me to the north stairs. I don't know by what force I was propelled. But now, two days later, I can look at the pictures and see: that was the side least affected by the second jet.
"In the stairwell, it was quiet. There were announcements on the loudspeakers, saying, 'It's safe. The building is safe. Don't panic.' I think they even told us we could go back to our offices, but I'm not sure. I was just going down, down, down, like an automaton. After the plane hit our building, and the building started shaking, there were no more announcements.
"Through almost everything, I felt amazingly calm, except for that one moment in the stairwell, when the building started shaking and I thought, I'm a goner. I wished I was back on the ninety-first floor, and I could jump. Because I could jump from the window—reluctantly, but I could do it—because then it is over. But to be trapped under rubble, that is worse. I remember, from the war, from Belgrade, what it is to be trapped under rubble.
"I don't really know where I was when the plane hit. I had with me some water, but when the stairs started shaking I dropped it. There was smoke, but not too thick. A colleague was with me when we reached the ground, and we came out of the building together.
"We started toward the Manhattan Bridge. I didn't even turn to look back. I was just walking. We had gone three blocks when the ground shook, and it suddenly got very dark, and everybody started running. I'm not too good at running, so I was just walking briskly. The smoke came from behind us, and everything became covered with a fine white powder. I actually thought it was an atom bomb, because that is what it's supposed to be like.
"When I heard that the Pentagon was also attacked, I became very worried about my son, because he often goes there for his work. I tried to phone him, but I couldn't get through. I walked and walked. Finally, at Penn Station, I managed to get through to his home, and my daughter-in-law answered. She gave the phone to my son, and he told me he was packing to go to New York to my funeral. They had been watching TV all morning, and they saw the buildings fall, and they had already buried me. It was a conclusion that I am dead that would be easily understood. But my son told me that a very strange thing happened. He reached up to take my picture from the shelf to take with him to New York, and a book fell from the shelf, and he saw a word on the cover, 'Miracles.' And three minutes later I called. I think it's a miracle. Do you believe in God?"
Mrs. Ilachinski had worked in the World Trade Center since 1980. She still talks about the buildings as if they exist. Only two weeks before the attack, she went on a tour to inspect the provisions in the structural design of the south tower. The design, she said, was far ahead of its time. "The building was designed to move three feet from the center, which was remarkable," she said. "When we first moved in, some people got seasick. And when there was a lot of wind there was screeching in the inner core. You know, the buildings were designed for a jet hit as well. But that was thirty years ago, and jets are different now. And nobody thought about the fuel."
At points, without warning, her architect's curiosity and practicality falter. "Guilt feeling you wouldn't believe," she said, with a voice full of pain. "At this time of life. And all those young people went. Strange. Very strange. And I am only asking why. All those poor people. Thousands and thousands."

PutOnYourBigGirlPanties 04 Feb 2006 - 22:37 CatherineJohnson

I'd noticed that eduwonk had been somewhat perseveratively quoting Margaret Spellings' line about putting on her big girl panties.....which was just odd enough not to cause me instantly to go read the article it came from....but then joannejacobs finally read the article herself, which galvanized me into action.....and let me tell you, I'm glad I got over to WAPO.
Margaret Spellings: In Her Own Class is fantastic:
Spellings is blunter than you might expect, vivid and bigger, as if her photo had been cropped and enlarged. She is a tall woman swinging an iguana-green purse, wearing edgy rectangular glasses and chewing gum. (She spits it into the garbage when you arrive, as if you were the teacher.) Spellings scanned the crowd: "Colin's the little hottie of the school."
She had her babies without pain medication. She's a tough enough manager to be called a "bulldog on details" by Rove; strong enough to raise her girls as a single mom when her first marriage ended; brave enough to admit that she dreams of being a torch singer draped over a piano; Texan enough to live by the motto (on her notepad) "Put on your big girl panties and deal with it."
the good news is —
— she's got a kid in middle school:
Middle school is tricky, Spellings said -- too many hormones and too loose a curriculum. When boys in white shirts and ties shuffled onstage, Spellings said, "They're so awkward, it cracks me up." Her own experience in seventh grade was "the low point of my life," she said. ". . . There's a lot of mush going on in middle school -- one of the nuts we haven't cracked in public education policy."

DougOnDeadlines 08 Feb 2006 - 15:38 CatherineJohnson
A couple of weeks ago I mentioned the term guillotine deadline.
Here's Doug:
When I was a periodicals editor, the term was "drop-deadline". 8-)
I did that job for long enough to develop a real defense-in-depth approach to deadlines:
"I'd like to get all your new information in by ...."
"I need your information by ... to make sure it gets in the next issue."
"I know I said that I need your information by ..., but you know we build in a little bit of slop in the schedule to handle the occasional late arrival."
"I've had a few other people late this issue, so I still have a little bit of time. Can you overnight it to me today?"
"I'm sending the book off to the printer tomorrow; if you can fax me the new stuff today, I should still be able to get it in."
"Don't worry, I can insert it at blueline. Of course, I'll have to charge you for the blueline change."
"I'm sending the bluelines back to the printer today. If you send it direct to the printer, we can still get it in. But you'll have to pay for all the printer's extra work."
"Nope, it's too late for this issue, but send it anyway; the next issue's deadline is tomorrow."
file under: it can always be worse, and it will be
So for the past couple of weeks I've been flogging myself to meet a self-imposed deadline, and then, of course, not meeting it, then setting a new deadline, then not meeting that one, and so on.
All in all, a wretched experience. I was glad to be done.
But now today I'm sitting around biting my nails waiting for everyone involved to figure out how I'm going to revise this project, which means I don't have to try to Write Anything today, i.e. I have some Free Time I could use productively to, say, Clean Up My Desk (& Surrounding Floor Area) ......and waiting around for other people to get back to me with loads of new work is even worse than doing loads of work & missing self-imposed deadlines in the first place.
Apparently, the fish oil isn't working.

The New York Times has identified a Whole New Problem: college students who send inappropriate email to their professors.

Jim Wilson/The New York Times
Jennifer Schultens [associate professor of mathematics at UC Davis] had a student ask what kind of notebook to buy.

Monica Almeida/The New York Times
Meg Worley, an assistant professor of English at Pomona College, has rules for student e-mail...."One of the rules that I teach my students is, the less powerful person always has to write back," Professor Worley said.
Various hypotheses are offered for the advent of this phenomenon, including this observation, from a professor of education:
Christopher J. Dede, a professor at the Harvard Graduate School of Education who has studied technology in education, said these e-mail messages showed how students no longer deferred to their professors, perhaps because they realized that professors' expertise could rapidly become outdated.
"The deference was probably driven more by the notion that professors were infallible sources of deep knowledge," Professor Dede said, and that notion has weakened.
I'm sure that's it.

Extra Credit: Define the universe, and give three examples.
source: Sample Exam Questions from Hell
Here's a real one:
My exams this semester are going horrible. I just love that feeling in which you leave an exam and you have no clue of how well you did. In fact, I feel as if I just wasted 13 weeks of my life studying, because my exams questions generally have nothing to do with the topic that I am studying. Our Con Law exam for instance wanted us to analogize an insignificant comment that Justice Breyer made in an interview about form and functionalism and how that relates to Supreme Court Commerce Clause decisions of the past 25 years. This is a least what I thought it said.
Thanks everybody I feel better now.

Ken left a link to this story about spell check:
Then there's always the other types of spell-check related problems, like this classic:
Spell-checking on his computer is never going to be the same for Santa Cruz solo practitioner Arthur Dudley.
In an opening brief to San Francisco's 1st District Court of Appeal, a search-and-replace command by Dudley inexplicably inserted the words "sea sponge" instead of the legal term "sua sponte," which is Latin for "on its own motion."
"Spell check did not have sua sponte in it," said Dudley, who, not noticing the error, shipped the brief to court.
That left the justices reading -- and probably laughing at -- such classic statements as: "An appropriate instruction limiting the judge's criminal liability in such a prosecution must be given sea sponge explaining that certain acts or omissions by themselves are not sufficient to support a conviction."
And: "It is well settled that a trial court must instruct sea sponge on any defense, including a mistake of fact defense."
The sneaky "sea sponge" popped up at least five times.
