The 1,200 teacher challenge

Dallas Morning News education blog reports the Dallas ISD needs to hire 1,200 new teachers by next fall — about 200 more than usual. 

We have great kids, we have a very good department, and Dallas pays better than most of the suburban districts in the area.  Vacancies existed through most of the school year.  Good candidates went other places.  It’s frustrating.

I’ll wager the hiring process would go faster, and work better, if teacher pay in Dallas were $5,000 higher.  I’d wager, as an administrator, that the $5,000/year raise for teachers would provide greater savings in hiring, tutoring, testing, and all other areas of academic performance.

But, then, I think supply/demand economics often works.  What do I know?

Two million minute challenge

Just over two weeks to graduation, son James is concerned about global competitiveness.  He’s off to study physics at Lawrence University in the fall; he is insistent I note the news in the paper this week.  I still have an active  stake in public schools, after all — good call, James.  Here’s his concern, below.

Each child has two million minutes of life over the four years of high school. Whether the U.S. can remain competitive in the global economy depends more than ever on how each child allocates those two million minutes.

A new film raises concerns that U.S. children are losing out against students from India and China.

Dallas Morning News business reporter Jim Landers wrote about the movie, “Two Million Minutes,” in an article May 6. It’s an indication of something that this is front page in the business section — an indication of genuine concern, one may hope.

Science and mathematics education gets the major attention in the film. One wishes this film could compete with the anti-science film “Expelled!” which still lingers malodrously in a few theatres across the nation.

Landers wrote:

2 Million Minutes argues that “the battle for America’s economic future isn’t being fought by our government. It’s being fought by our kids.”

And in a series of international comparisons, the U.S. kids are not doing so well. The one area where they score better than the rest is self-confidence.

Once they leave the eighth grade, students have a little more than 2 million minutes to get ready for work or college and the transition to being an adult. This documentary, made by high-tech entrepreneur Robert Compton, follows two high school seniors in Carmel, Ind., two in Bangalore, India, and two in Shanghai, China, to see how they use their time.

All six are bright, accomplished, college-bound individuals.

Our students spend a lot of time watching TV, working part-time jobs, playing sports and video games, but not so much on homework. The Chinese kids spend an extra month in school each year, more hours at school each day and more hours doing homework. By the time they graduate, Chinese students have spent more than twice as much time studying as their U.S. counterparts.

While one may hope kids will pay attention, one may be unhappy to recall the topic, and many of the same or similar numbers, were published nationally in the 1980s by the Office of Educational Research and Improvement (OERI) at the U.S. Department of Education. I remember it well, since I was publisher for some of the work.

The website for the movie offers more details, including a calendar of screenings. DVDs are available, but at very high prices — $25 for home use, $100 for school or non-profit use. I’d love to show it to students; I can get a couple of much-needed PBS videos for that same price. I hope producers will work to arrange distribution competitive with opposition movies like Stein’s. I’ll wager “Expelled!” will hit the DVD market at about $10.00, with thousands of DVDs available for free to churches and anti-science organizations.

Landers chalks up some of the stakes, and we should all pay attention:

FALLING BEHIND IN EDUCATION

Nearly 60 percent of the patents filed with the U.S. Patent and Trademark Office in the field of information technology now originate in Asia.

The United States ranks 17th among nations in high-school graduation rate and 14th in college graduation rate.

In China, virtually all high school students study calculus; in the United States, 13 percent study calculus.

For every American elementary and secondary school student studying Chinese, there are 10,000 students in China studying English.

The average American youth now spends 66 percent more time watching television than in school.

Education spending, per pupil, apples to apples

Utah rejected education vouchers last November, so the release from the Census bureau at the first of April probably got overlooked as not exactly important — I saw no major story on it in any medium.

Maybe it was the April 1 release date.

Whatever the reason for the lack of recognition, the figures are out from the Census Bureau, and Utah’s at the bottom end of spending per student lists, in the U.S. I wrote earlier that Utah gets a whale of a bargain, since teachers work miracles with the money they have. But miracles can only go so far. Utah’s educational performance has been sliding for 20 years. Investment will be required to stop the slide.

Utah’s per pupil spending is closer to a third that of New York’s.

Of course, spending levels do not guarantee results. New York and New Jersey lead the pack, but the District of Columbia comes in third place. Very few people I know would swap an education in Idaho, Utah or Arizona, the bottom three in per pupil spending, for an education in D.C.

Public Schools Spent $9,138 Per Student in 2006

School districts in the United States spent an average of $9,138 per student in fiscal year 2006, an increase of $437 from 2005, according to a U.S. Census Bureau report released today.

Public Education Finances: 2006 offers a comprehensive look at the revenues and expenditures of public school districts at the national and state levels. The report includes detailed tables that allow for the calculation of per pupil expenditures. Highlights from these tables include spending on instruction, support services, construction, salaries and benefits of the more than 15,000 school districts. Public school districts include elementary and secondary school systems.

All the census statistics are on-line, for free. Policy makers can mine these data for insights — will they? You may download the data in spreadsheet or comma-delimited data form.

The rest of the press release is pure policy talking points:

Public school systems received $521.1 billion in funding from federal, state and local sources in 2006, a 6.7 percent increase over 2005. Total expenditures reached $526.6 billion, a 6 percent increase. (See Table 1.)

State governments contributed the greatest share of funding to public school systems (47 percent), followed by local sources (44 percent) and the federal government (9 percent). (See Table 5.)

School district spending per pupil was highest in New York ($14,884), followed by New Jersey ($14,630) and the District of Columbia ($13,446). States where school districts spent the lowest amount per pupil were Utah ($5,437), Idaho ($6,440) and Arizona ($6,472). (See Tables 8 and 11.)

Of the total expenditures for elementary and secondary education, current spending made up $451 billion (85.7 percent) and capital outlay $59 billion (11.2 percent). (See Table 1.)

From current spending, school districts allotted $271.8 billion to elementary and secondary instruction. Of that amount, $184.4 billion (68 percent) went to salaries and $58.5 billion went to employee benefits (22 percent). Another $156 billion went to support services. (See Table 6.)

Of the $156 billion spent on support services, 28 percent went to operations and maintenance, and 5 percent went to general administration. Of the states that used 10 percent or more of their support services on general administration expenditures, North Dakota topped the list at 14 percent. General administration includes the activities of the boards of education and the offices of the superintendent. (See Table 7.)

Of the $59 billion in capital outlay, $45 billion (77 percent) was spent on construction, $5 billion (8 percent) was spent on land and existing structures, and $8.7 billion (15 percent) went to equipment. (See Table 9.)

State government contributions per student averaged $5,018 nationally. Hawaii had the largest revenue from state sources per pupil ($13,301). South Dakota had the least state revenue per student ($2,922). (See Table 11.)

The percentage of state government financing for public education was highest in Hawaii (89.9 percent) and lowest in Nebraska (31.4 percent). (See Table 5.)

The average contribution per pupil from local sources was $4,779, with the highest amount from the District of Columbia ($16,195), which comprises a single urban district (and therefore does not receive state financing). The state with the smallest contribution from local sources was Hawaii ($265). (See Table 11).

The percentage of local revenue for school districts was highest in Illinois (59.1 percent) and lowest in Hawaii (1.8 percent). (See Table 5.)

On average, the federal government contributed $974 per student enrolled in public school systems. Federal contributions ranged from $2,181 per student in Alaska to $627 in Nevada (See Table 11).

The percentage of public school system revenues from the federal government was highest in Mississippi (20.1 percent) and lowest in New Jersey (4.3 percent). (See Table 5.)

Spending on transportation represented 12.4 percent of support services. New York and West Virginia spent the largest percent from support services on transportation (21 percent). Hawaii (5.4 percent) and California (7.2 percent) spent the least. (See Table 7.)

Total school district debt increased by 8.5 percent from the prior year to $322.7 billion in fiscal year 2006. (See Table 10.)

Carnival Catch-up: Personal Finance

Behind on our carnivaling again . . . alas, not because we’ve been soaking in the tub, either.

Texas teachers, take note of the 149th Carnival of Personal Finance hosted by The Happy Rock. If you can’t find material there to bolster your personal finance curriculum, you need a lot more coffee.  Lots of posts on saving and investing and how to make it work on limited budgets, good stuff for the classroom.  Some are rather curious though — this one, from Squawkfox, suggests women should go around virtually naked in a sense, keeping no important documents or items in their purses.  Where should a lady carry her check book, seriously?

Science funding: Kicking our future away

Drat.

We get Charlie Rose’s program late here — generally after midnight. I’m up to my ears with charitable organization duties (”Just Say No!”), work where I came in midstream, family health issues, and other typical aggravations of trying live a well-examined life.

I caught most of an hour discussion on science in America, featuring Sir Paul Nurse, president of Rockefeller University and Nobel laureate, Bruce Alberts, editor of Science, Shirley Ann Jackson, president of  Rensselaer Polytechnic Institute, Harold Varmus, Nobel winner and president of Memorial Sloan-Kettering Cancer Center, and Lisa Randall, the Harvard nuclear physicist (string theory).

It was a great policy discussion. It had great humor, and great wisdom. And at the end, Rose thanked Nurse and others for helping him put on a 13-part seminar on science policy.

Thirteen parts? And I caught just the last few minutes of #13?

There is the Charlie Rose archives! Here’s the show I caught, “The Imperative of Science.” Great discussion. Scary — Lisa Randall notes that the action in physics has moved to CERN, in Europe, and the search for the Higgs Boson. Varmus and Nurse talk about restrictions in funding that bite at our ability to keep the world lead in education and science. Educators, especially in science, should watch.

Are we kicking away our ability to lead in technology, health care, and other vital economic areas? One cannot help but wonder in listening to these people discuss the difficulty of getting support for critical research during the Bush administration. They each stressed the hope that the next president will be one literate in science.

Pfizer underwrote the series. The entire series is available for viewing at a site Pfizer set up.  (Signs of change:  Notice that physics is represented by two women; there are signs of hope in American science.)

Go see, from Pfizer’s website on the series:

Plants refuse to listen to climate change skeptics

March 20 brought the Spring equinox, but our daffodils have been up for a couple of weeks. Spring comes a little earlier every year.

That fact, and news stories like these below must cause great angst in the bowels of the offices of U.S. Sen. Tom Coburn (R-Okla.) and other places climate change deniers hold sway. One can almost imagine some poor sap of a Coburn minion laboring away long into the night trying to devise legislation that will prevent Canadian thistles, redbuds, marigolds, wheat, soybeans and corn from reading about climate change or going to see Al Gore’s movie, and getting the wrong ideas.

I hope that minion is imaginary.

Here’s story #1: The Tuesday Science Section of the New York Times carried a story by Jim Robbins, “In a Warmer Yellowstone Park, a Shifting Environmental Balance.” Longtime readers probably know of my deep affection and ties to Yellowstone and the Mountain West. So of course this story catches my eye.

Robbins details an interesting set of changes being studied by Robert L. Crabtree, who is “chief scientist with the Yellowstone Ecological Research Center in Bozeman, Montana”: Invasive Canadian thistle, an exotic weed harries cattlemen throughout the world for the ways it destroys pasture land; despite its name, this thistle is an exotic from Asia, accidentally introduced to the Americas. The Lamar Valley in Yellowstone, formerly a wetland, continues to dry as a result of rising temperatures and lack of usual rainfall (a predicted effect of global climate change). Canadian thistle loves drying wetlands, and has invaded along the Lamar River. Officials fought the invasion for several years, but the fight seems lost.

The changes are dramatic, to observant ecologists:

Enter the pocket gopher, a half-pound dynamo that tunnels into the ground near the surface. The gophers love the abundant, starchy roots of the plant and burrow beneath it to harvest the tubers. What they do not eat they stockpile under plants or rocks.

The expansion of pocket gophers and thistle is not gradual, Dr. Crabtree said, but a rapid positive-feedback loop. As the gophers tunnel, they churn surface soil and create a perfect habitat for more thistle. In other words, the rodents help spread the plant. And more plants, in turn, lead to more pocket gophers.

“The pocket gophers are unconsciously farming their own food source,” said Dr. Crabtree. Their numbers here have tripled since the late 1980s, he said.

For their part, grizzly bears have discovered the gophers’ caches and raid them. As a result, the Lamar Valley is pockmarked with holes where grizzlies have clawed up bundles of roots. Bears also devour gophers and their pups.

Dr. Crabtree thinks the bears started feeding in earnest on the new food source in 2004 — a poor year for another bear staple, the white bark pine nut. Now, he adds, they seem to be eating the gophers and roots more routinely.

Tom Oliff, chief scientist for Yellowstone, confirms that the growing season for the park has expanded 20 days a year since the mid-1990s, which may explain the spread of Canada thistle. Mr. Oliff said the park reduced control efforts because evidence showed that the plant ebbed and flowed and that the range would probably shrink on its own.

One doesn’t have to be a fan of the Craigheads or a biologist to be dimly aware that the Yellowstone ecosystems are intensely studied and intensely threatened. Climate change played a contributing role in the cataclysmic fires in the park in 1988; reintroduction of wolves still sparks some controversy, though the return of a top predator has already produced other dramatic changes in Yellowstone ecosystems. Yellowstone is home and refuge to a wild bison herd, and beautiful and unique — generally revered as a “crown jewel” of America’s features.

Nor does one need to be a climate scientist to recognize the signs of warming listed in the article, and the dangers that are implied: Drying wetlands, invasive species, dying traditional foodstocks for grizzlies, population explosions that almost always are a symptom of serious trouble in an ecosystem.

So I was surprised, dumbfounded even, to see The Unbearable Nakedness of CLIMATE CHANGE claim this as a good story. Why?

Something absolutely unheard-of before: an entire New York Times article talking about Global Warming but… with no hint of impending doom or catastrophes:

In a Warmer Yellowstone Park, a Shifting Environmental Balance by Jim Robbins - published: March 18, 2008

Destruction of wetlands, displacement of native species, upset of the ecological apple cart — and this is “no hint of impending doom?” (While you’re at the NY Times site, also see this story, about how warmer temperatures threaten the grizzly.)

Here’s story #2:

Cherry blossoms in Washington, D.C., now appear weeks earlier than they used to. April 5 was the date of the debut of the blossoms 30 years ago, according to a story at National Public Radio, but they are out already and will have peaked by the end of March this year.

Washington’s blossomless Cherry Blossom Festivals (the dates for the festival have not kept pace) provide one more indicator that spring comes earlier. A geographer from Virginia Tech, Kirsten de Beurs, uses remote sensing satellite data to look at the dates plants spring forth, and has determined that spring is moving up 8 hours every year. (Go to the NPR site and listen to the story.) (This science is called “phenology,” the study of the timing of biological phenomena.)

Here’s the problem for climate change deniers: How can they convince the birds, bees, grizzlies, and especially the trees and flowers, that they shouldn’t be acting as if the climate were changing? How can the climate change skeptics get the Canadian thistles to stop invading, the Japanese blossoming cherry trees in the Tidal Basin to delay their blossoms, the bluegrass of Kentucky to delay its greening, the prairies of Kansas to delay the wildflowers and grasses?

Have all those plants been suckered in by Al Gore’s movie? Don’t those plants know that Anthony Watts has shown that the weather measuring stations across the U.S. are placed wrongly, and so there cannot be warmer weather?

Church authorities got Galileo to lie low on the issue of heliocentricity centuries ago; but according to the legend, as he left the room where he had agreed to keep quiet, he muttered, “but still, it moves,” referring to the motion of the Earth about the Sun. This is the problem of the climate change deniers: Still, the climate changes.

Canute couldn’t command the tides not to flow; climate change deniers cannot command the flowers not to bloom. That force that through the green fuse drives the flower? It’s the destroyer of skepticism, too. Climate change skeptics curse it today.

Carnivals! Beach browsing for spring break

Spring break, lots of work to do (no beaches for me). Have I neglected noting the carnivals? There are a lot of good posts gathered in some of them.

Liberals

Tangled Up in Blue Guy hosts the 60th Carnival of the Liberals. Pay particular attention to Digital Cuttlefish’s little spur-of-the-moment poem on Sally Kern, an Oklahoma state representative who was caught red-eared, on tape, in a bigoted rant. Poetry doesn’t get the respect it deserves; this guy shows real wit in his rhyming.

Prehistory, archaeology

Four Stone Hearth #36 cooks along and warms our brains over at Afarensis. I think every history teacher and every geography teacher should visit this carnival from time to time, to find some of the best new stuff for the early chapters of every history course, the prehistoric human section that is never as good in the class textbook as it is in the journals or in these blogs. Who among us hasn’t had someone ask for the “final, definitive reason” the Neandertals went extinct? Instead of just answering “we don’t know,” you can refer a student to the “mad Neandertal” hypothesis, and ask them to report back on it from A Very Remote Period Indeed). Science, and history, are not settled on these issues — how better to let students see that than to experience some of the discussion? Psychology teachers probably should note this post from Not Exactly Rocket Science, on PET scans of human and chimpanzee brains while the subject is communicating. That’s just two posts in the carnival.

Education

Learn Me Good hosts the 162nd Carnival of Education, the March Mathness Edition. Take a look at Dave on Ed’s post about how school administrators are quick to jump on calling for change to match whatever is the latest fad in education, but slow to provide teachers with the training required to make the changes work. What fad is he talking about? Well, all of them — but you remember the talk a couple of weeks ago about the Finns getting education right? Mom is Teaching has some comments about the Finns beating Americans.

Psychology and neuroscience

I’m watching psychology more closely these days, especially with older son Kenny now working on a neuroscience degree, so I’ve been paying more attention to Encephalon, the carnival on psychology and neurosciences – Encephalon 40 finds a home at Mind Hacks. Hitting almost all my buttons, there is a pointer to a post discussing what is the real history of psychology at Advances in the History of Psychology — what counts as history? Great discussion. Encephalon 41 is due on March 17, at Pure Pedantry.

History

History Carnival 62 has been up for a couple of weeks at Spinning Clio. I just got there a couple of days ago — and you need to go see it, too. The History Guru has a series of podcasts on western civilization, the Western Intellectual History Lecture Series. Can you use this in your classes? Figure out how to use it in your classes. If you’re not making iPod recommendations for your students, you’re missing the boat and so are they. Go check it out at least. Such activities threaten to drag teaching into the last decade of the 20th century. There’s hope we can drag teaching into the 21st century sometime before 2090. The President of France proposes that each 10 year-old child in France memorize the history of one child deported from France during the Holocaust. Good idea or not? See the discussion here (yes, it’s in French; this is the internet, put on your grande fille culottes or pantalons adulte and deal with it). [Why is it that high school history texts never explain the origin of the name of the political movement in Paris, the sans-culottes? How could any kid fail to remember a movement known as "no-pants?" Do the book authors not know that kids would be interested?]

The History Carnival is particularly rich for high school teachers, I think; see these posts:

Over at Progressive Historian, contributor “midtowng” believes that the S&L Crisis is repeating today and compares it to the S&L crisis of the 1980’s .

Jon Swift exclaims Castro Resigns! Sanctions Work!

“It has now been forty years since May ‘68, and yet we still haven’t gotten over it.” Greg Afinogenov looks at why.

Economics

Is the American Economics Blog Carnival the economics carnival I’ve been searching for? Struck in Traffic hosts the March 1 edition. Hmmmm. Not sure.

Okay, enough of the Midways. Where is the Fletcher’s State Fair Corny Dog Shack? (Controversy there, too!)

Desperate, frightened, angry at America, Republicans and conservatives spread hoaxes

With voters going overwhelmingly for Democrats in the past few weeks, Republicans and conservatives seem to be getting desperate for a fix of bad news for Democrats — so desperate they’ll create hoax news if they can’t find any real stuff (as if the wars were not bad enough, not deserving of our attention enough).

Some hoaxers spread the old hoax about Nancy Pelosi asking for new taxes. Not true.

That doesn’t stop more hoaxers from spreading the falsehoods. And spreading them. And spreading them. And spreading the hoaxes. Lying to Vietnam veterans. Spreading the false hoaxes via “answer” boards. And spreading the falsehoods. Lying to gullible political activists. Spreading the hoax to even more, gullible political activists.

Don’t any of these people read newspapers? Haven’t they got the internet, which would link them to Pelosi’s office, or to the Thomas site at the Library of Congress to track the supposed legislation, or to Snopes.com, or Urban Legends?  Don’t any of these hoax spreaders have the sense or decency to ask whether the proposal makes any sense?

Critical thinking is more than saying “I think [people I disagree with] are ugly.”

Joseph Juran dead at 103

Anyone in quality control would recognize the name; more people in business will recognize the principles.

Joseph Juran, who made “Six Sigma” a symbol of high quality control and pointed the way to statistical analysis of problems that factory floor workers could understand and use, is dead at 103.

He created the Pareto principle, also known as the 80-20 rule, which states that 80 percent of consequences stem from 20 percent of causes. Today managers use the Pareto principle, named for an Italian economist, to help them separate what Mr. Juran called the “vital few” resources from the “useful many.”

“Everybody who’s in business now adopts the philosophy of quality management,” David Juran said. “He came along at just the right time. Most of the reference books that have been written about this field are either books that he wrote or imitations.”

Among his best-known works were the “Quality Control Handbook” in 1951, the first mathematically rooted textbook on product quality, now entering its sixth edition, and “Managerial Breakthrough” in 1964, which described a step-by-step improvement process that inspired the Six Sigma and lean manufacturing philosophies.

Perhaps a mark of how far out of favor serious quality control has fallen, the New York Times article makes no mention of other quality control pioneers who worked with Juran, such as W. Edwards Deming, nor does it note the amazingly long list of companies who used the principles to achieve greatness, some of which were later skewered by other economic problems.

And I’ll wager that not one school principal in 1,000 knows who Juran was or how his methods might improve education.

(Photo from publicity still, the same photo used on most of Dr. Juran’s books.)

Gresham’s Law: DDT disinformation crowds out facts

I love irony.

Henry VIII devised a novel way to save money. He ordered coins be minted containing silver, as during the reign of Henry VII, but he ordered that the purity of the silver be reduced. Edward VI continued the policy so that, by the time of the rule of Queen Elizabeth I, royal advisor and financier Sir Thomas Gresham observed that most of the old, high-silver content coins were out of circulation, hoarded by people against future inflation, allowing the lesser-valued money to circulate. Gresham told Elizabeth the bad money drove out the good money.

The principle had been observed earlier by Aristophanes and others. It is known in modern economics as Gresham’s Law, since 1858 when British economist Henry Dunning McLeod decided to honor Gresham by naming the rule after him.

The bad drives out the good, the cheap drives out the more expensive, gossip drives out good information – the principle is widely observed in areas beyond economics.

And so it is that with regard to DDT, the good information about the dangers of DDT and the benefits of restricting use of the chemical has been driven out of the marketplace by bad information claiming DDT is safe, and ignoring the significant benefits reaped when massive use of DDT was stopped.

And here’s the irony: DDT-happy critics of good environmental policy now claim to be the good information driven out by the “bad” information of DDT’s harms. No kidding. A columnist named Natalie Sirkin, in a column delivering almost nothing but bad, vile information, says bad information drives out the good, never once noting the irony.

The defense of DDT was, from the beginning, a lost cause. A few of us vainly hoped that science would prevail. We soon found that Gresham ’s Law, which states that bad currency drives out good currency, applies to science as well as to economics.

No kidding it applies. Do a Google search for “DDT” today and you’ll find all over the internet the disinformation of Gordon Edwards’ ghost and junk science purveyor Steven Milloy. You will have a difficult time finding any solid study showing how DDT nearly killed off the American bald eagle, however, and you’ll have to do a targeted search to learn of any dangers of DDT — information on human toxicity is almost impossible to find, though it’s easy to find many recountings of Gordon Edwards’ bold drinking of a teaspoon of DDT before lectures.

(Natalie and Gerald Sirkin write for the American Spectator; at this writing, Google features warnings on all of their material at the time of this writing, saying the site host may try to insert “malicious software” on your computer — so I have not linked there. This problem should sort itself out, I hope.)

(The Environmental Protection Agency (EPA) works to get a history of the agency up on the ‘net; a lot from the DDT ban era is now available at the EPA site for scholars; Milloy will not be happy to have factual rebuttal officially and easily available.)

Below the fold, I’ll offer a point-by-point rebuttal of the bizarre claims in favor of DDT and against the noble public officials who worked to restrict its use.

Geography revolution, next wave: Ready in your classroom?

Depression presents a serious occupational hazard, moving back and forth between the classroom and business, classroom and internet. When do administrators and legislators get serious about catching up education?

Microsoft plans a product announcement at the end of this month. Rumors claim it’s a new version of Photosynth. Photosynth mades “3D” touring by computer possible for almost any destination.

I’ll wager not a single classroom in the nation is ready to make this work. If you disagree, I’d love to hear about the class that can make use of it.

System requirements for Photosynth won’t tax the computers that most high school gamers use, but they are beyond most of the classroom computers I’ve seen in the last five years.

Probably more to the point, curriculum designers in public schools don’t even have Google Earth on their horizons. Photosynth? I’ll wager it’s not even on the radar screens of GIS users in the nation’s Council of Governments (COGS).

Geography is an exploding discipline. GIS and computerized map programs make cell phone companies go, not to mention oil and gas exploration, coal mining, air pollution monitoring (for building new power plants, for example), and road building. GPS helps drive express shipping, and all other shipping. RFI and GPS together are revolutionizing retail.

You must know how to read a map just to get a job delivering pizza.

But 9th grade geography classes? The exciting stuff is absent today.

At the Texas Education Agency (TEA), officials fret about how to stop science from being taught in science classes, for fear the facts will skew the religious beliefs of their children. They need to worry about their children not even getting hired by the pizza delivery company for being ignorant of nature and science, and the maps that show them. In a competitive, technologically savvy world, inaction, dithering and damaging action by the TEA mean our kids won’t even have a prayer.

America by Air, the promise of on-line history education

Looking for something else I found the Smithsonian Institution’s on-line history of air passenger travel in the U.S., America by Air.

I can easily see a time when a student with a computer terminal gets an assignment to look at some of the activities available at a site like America by Air, with on-line quizzes as the student progresses through the exhibits.

How far away are we? Two questions: Does your school provide an internet-linked computer for each student? Do you have the software or technical support to give an on-line assignment and track results?

Teaching stays stuck in the 19th century, learning opportunities fly through the 21st.

Indians and energy: Public symposium on history, economics, politics and culture in the Four Corners

Southern Methodist University’s Clements Center for Southwest Studies will host a high-powered symposium in April, “Indians and Energy: Exploitation and Opportunity in the American Southwest.”

The symposium is set for Saturday, April 12, 2008, at McCord Auditorium in SMU’s Dallas Hall, 8:30 a.m. to 5:00 p.m. Teachers and community college professors may earn up to 7 hours CEU credits. Registration is available on-line. The $20.00 fee includes a luncheon; conference-only registration is an amazingly inexpensive $5.00.

Conference organizers are looking at a second wave of energy resource development in the Four Corners region, especially, following on earlier development of uranium ore extraction, and coal-fired power generation.

The symposium and the resulting book of essays will provide an historical context for energy development on Native American lands and put forth ideas that may guide future public policy formation. Collectively, the presentations will make the case that the American Southwest is particularly well-suited for exploring how people have transformed the region’s resources into fuel supplies for human consumption. Not only do Native Americans possess a large percentage of the region’s total acreage, but on their lands reside much of the nation’s oil, coal, and uranium resources. Regional weather patterns have also enabled native people to take advantage of solar and wind power as effective sources of energy. Although presentations will document histories of resource extraction and energy development as episodes of exploitation, paternalism, and dependency, others will show how energy development in particular has enabled many Indians to break from these patterns and facilitated their social, economic, and political empowerment.

My second job out of high school, and through much of my undergraduate days, took me to Farmington, New Mexico, and far around the area for the Air Pollution Laboratory at the University of Utah’s Engineering Experiment Station, to measure air quality and effects of air pollution resulting from the Four Corners Power Plant, as the San Juan Generating Station was under construction.

I’m planning to attend the symposium.

Especially after last Saturday’s sessions for history teachers at SMU (the Stanton Sharp Symposium), I highly recommend these programs for their ability to charge up high school teachers to better classroom work. This is history, and economics, at its best, looking to improve public policy and help people.

Planned presentations are listed below the fold, copying the information from the website for the symposium.
