More carnivalia, stoned version

February 18, 2008

Oh, remember to check out the latest 4 Stone Hearth.  This carnival of archaeology was posted at Our Cultural World last week, its 34th outing.

John Hawks has a post featured about Neandertal’s roaming habits, all determined from a tooth.  Interesting archaeology, interesting anthropology, and just how can they tell all that from one tooth? Hawks’ blog has articles I’ll use in U.S. history, world history, psychology, and maybe economics.  One of the best things about 4 Stone Hearth is the way it points to outstanding sources.

Got a tagger in your classroom?  He (rarely a she) may be interested in ancient taggers — if we may call them that.

If you live on the Pacific coast, or in the Caribbean, should you worry about your local volcano?  A Very Remote Period Indeed pointed to a paper that suggests the hominids found at Dmanisi were a family killed by a volcanic eruption — perhaps your local volcano can help you become immortal, after a fashion?

Also featured is an article about language development at a blog I only recently discovered, Not Exactly Rocket Science.  It’s another blog worth watching.


Gresham’s Law: DDT disinformation crowds out facts

February 18, 2008

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.

Sir Thomas Gresham (c. 1519 – 21 November 1579), British financier and advisor to Queen Elizabeth I and earlier regents. Portrait c. 1554 by Anthonis Mor.

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?

February 15, 2008

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.

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.

Kosovo: Running it up the flagpole

February 10, 2008

Living through history: Independence for Kosovo looks more likely; residents work to pick a flag for the new nation. Several serious hurdles remain; Russia promises to block UN action to support Kosovo independence from Serbia, in the Security Council.

Proposed flag for Kosovo

That flag chart on your wall could be obsolete in the near future. What do your geography and world history students know about the new nation of Kosovo?

January 28: Anniversary of Pueblo capture

January 23, 2008

January 28 will be the 40th anniversary of the capture of the U.S.S. Pueblo by gunboats from North Korea (or Democratic Peoples Republic of Korea, DPRK), which led to some of the more interesting hoaxes of modern times.

Just watching the calendar in this 40th anniversary of 1968.


Park your camel, the music’s begun

January 12, 2008

As long as we’re in Mali anyway, why not arrive a couple of days early for this other music festival? Michael Kessler writes about the Festival du Chameau in the Sydney Morning Herald, “The sound of the desert blues”:

A week ago, when the doctor was jabbing me with yellow fever, polio and hepatitis shots and supplying malaria tablets, I’d tried imagining what a camel festival would look like. The Festival du Chameau [in its third year in 2008] is the brainchild of Tinariwen, the international darlings of world music – a group of Touareg nomadic musicians, purveyors of the desert blues, whose political past combined with their hypnotic electric guitars make them local heroes in this, the Adrar des Iforas region of Mali.

Toronto Globe and Mail reporter Stephanie Nolen accompanied a group of Inuit musicians to Mali, documented in a blog for the newspaper, Trail to Timbuktu; from her reports, we know the festival is underway, music is on the dunes:

There’s no down-in-front with a camel, really.

The 8th Festival in the Desert began a couple of hours ago, with several thousand people sitting and standing in the cool, white sand at the edge of the oasis at Essekane. The sun set just as the event kicked off, silhouetting robed men, veiled women and camels on all the surrounding ridges. On the small, raised stage there were speeches by notables including the local governor and Mali’s Minister of Culture.

Then the music began, with the opening provided by Tamnana, a traditional ensemble of men and women from Essekane who drum, chant, clap and ululate. They’re a big hit with the locals, and it turns out that demonstrations of musical appreciation hereabouts take the form of camel tricks. When the spirit moves them, nomads on camelback suddenly charge down from the dunes to the front of the stage, where they coax their camels down to “walk” on their front knees a much-admired feat. Or they dismount and launch sudden sword fights with phantom opponents, before swinging back up and charging the camel back and forth in front of the stage a few times. It’s the Tuareg version of the mosh pit, and it’s magical to watch, but it does tend to blot out the action on the stage.

News still travels slowly out of Mali’s desert, though. Most of the news about the Mali Festival in the Desert comes in the form of festival veterans spreading the music, in other, far-flung venuues.

Influences of the Essakane Festival of the Desert reach Salina, Kansas, where the Salina Journal talks about the music of Toubab Crewe, a group of North Caronlians who have performed at the big Mali festival in the past.

Oregon feels it, too: MacArthur Foundation grant recipient Corey Harris, a veteran bluesman whose work was featured in the PBS series on the blues, especially his work in Mali with the late Ali Farka Toure, performs at the Rogue Valley Blues Festival in Ashland, Oregon, on January 18 (that’s the Southern Oregon Mail Tribune, not Mali Tribune).

Mali, and Africa, have much more than just these few festivals. Why should we concern ourselves with the Essakane festival at all? Africa. PopMatters carries a column by journalist Mark Reynolds, reviewing events and arts in Africa in 2007, with a look to 2008. It’s a survey of events and publications, but it’s a good backgrounder for a high school student in Africa concerns, an article that should suggest connections to be made in geography, history, government and economics courses.

Thanks to Ann at Peoples Geography for the correction — Sydney Morning Herald.


Festival au Desert Essakane! January 10-12, 2008

January 10, 2008

BBC’s internet services carried this slide and sound account of the 2007 Essakane festival in far off Mali; this is one music festival I would really like to attend. Snippets of songs crop up on NPR or PRI (especially The World), and on PBS, and in record stores with really savvy staff — or where Putumayo discs are on sale. Everything I have heard from these festivals is very, very good.

Robert Plant helped make it famous with his 2003 performance. But its fame is relative; it’s famous only among a select group of people — those who have heard the music.

[Alas, Vodpod died, and the video that I had captured via that service seems to appear nowhere else on the web.  If you should find the piece by Paula Dear which the BBC broadcast in 2007, please note it in comments.]

Vodpod videos no longer available. from news.bbc.co.uk posted with vodpod

.

The festival is set for January 10-12 in 2008. Who is playing? Where are news stories? Where are the CDs? Here’s the official website.

Geography teachers, think of the possibilities this festival offers for fun in the classroom! Adam Fisher wrote about it for the New York Times a couple of years ago:

My real aim is Essakane, an obscure desert oasis a half-day’s drive beyond Timbuktu, and the site of what’s billed as the “most remote music festival in the world.” It’s a three-day Afro-pop powwow held by the Tuareg, the traditionally nomadic “blue people” of the Sahara.

It’s a tribe often feared for the banditry of its rebels and respected for the fact that it has never really been conquered. Historically its great power came from its role in the trans-Saharan trade in gold, slaves and salt. Even now, Tuareg caravans make the 15-day journey south from the northern salt mines to Timbuktu on the Niger River. They rest their camels during the day and use the stars to navigate at night. The skin tint of the nomads comes from the indigo dye they use for their turbans and robes, which leaves a permanent stain.

What more exciting stuff do you have in your classroom on the Tuareg? Does it resonate better with your teenagers than this story would?

Addictive quizzes on world geography

January 4, 2008

Well, this is fairly addictive: The Travel IQ Quiz from TravelPod

I’d love to have every kid in the class with a computer to take this thing, or pieces of it, to drill on it, and I’d love the ability to add new stuff to it.

How’d you do? What do you think — are there classroom possibilities here?  (I’ve tried to make the widget work, below . . .)

Follow a graduate student to Antarctica

January 3, 2008

Penguin Burgers appears to be a blog of a graduate student who will be off to Antarctica on a project, working with a team at North Carolina State University.

The blog appears to be rather an afterthought, an add-on. But consider: What if your class were able to follow this guy to Antarctica, and keep up regular communication with him through the blog?

There’s some great potential there. I plan to watch. Looks like this fellow is really looking forward to the trip.


Test pressures hammer social studies instruction

December 19, 2007

He’s obviously a bright kid. He’s got good grades. It’s honors U.S. history, which is supposed to be rigorous, to prepare the kid for college studies.

But we’re drawing blanks from the kid on basic stuff: What’s the significance of 1776? Jamestown is in what state? Who was the commanding general of the American Revolution, George Washington or Abraham Lincoln? During the Civil War, on which side did Robert E. Lee fight? Or was he that dude from the Revolutionary War? Was the 1849 Gold Rush in Texas or California?

During the practice tests, he’s got all the skills: Two-colored markers to analyze the reading passages, circles and arrows to show which parts are important to consider. He can break the test question and reading down into all the “proper” parts, it’s a testing procedure he’s been practicing since third grade. After 8 years, he knows it well.

But he’s not sure whether the British fought in the American Civil War.

It’s a composite picture, but not composite enough for any of us to breathe the relief sigh. Too many students I get in class do not have the basic facts down that they need to make sense of anything else in the history course — or economics or geography course — that they struggle in now.

Many of these students have good test scores, too. The test doesn’t phase them, but their performance is not what it ought to be. Instead of acing the annual state exam, they take a couple of hours and complain that it’s a stupid exam with stupid questions.

We’ve taught them “tricks” to analyze the test questions, but they don’t have the background in the subject that they should have in order to quickly answer basic questions. The tricks get them through an exam, but it’s a poor substitute for knowing the material.

How does this happen?

Many schools across the nation have shorted social studies. Confronting pressure to raise average school test scores, basic social studies has been cut back in elementary and middle grades (kids know that stuff anyway, right?). Social studies is crowded out of the curriculum in favor of testing skills, or instruction in science and math.

I suspect much of the instruction in science and math is similarly shallow. Students learn how to analyze the test question, but they don’t know how to do the math required.

We know that students learn more when they spend more time on the learning tasks. Learning time is reduced for testing skills instruction.

Social studies take the hit particularly hard. According to a commentary by Judith Pace of the University of San Francisco, in Education Week this week (subscription may be required):

Surveys have reported reduced instructional time in various states, and organizations such as the National Council for the Social Studies have responded with letters and statements to Congress. Social studies educators have begun to lobby their lawmakers. But the apparent mainstream acceptance of drastic reductions in the amount of time and attention given to one of elementary education’s core academic subjects is shocking. We are in danger of losing a generation of citizens schooled in the foundations of democracy—and of producing high school graduates who are not broadly educated human beings.

In my own state of California, where history/social studies is not tested until 8th grade, this trend began with the state’s Public Schools Accountability Act of 1999, and has accelerated with the No Child Left Behind law. The social studies squeeze occurs disproportionately in low-performing schools with large minority and low-income populations that are under intense pressure to raise scores. And this, too, has alarming implications for educational opportunity and civic participation.

(More of Light’s commentary below the fold.)

One of the old saws of the quality movement in industry (now sadly abandoned in too many places) is “You get what you measure.” We measure average achievement. Consequently, we stifle outstanding achievement, and we don’t give most of the children the background they need to be good citizens.

I see it in students who just don’t know the basics. We should not need to spend time teaching that Abraham Lincoln was not at the Constitutional Convention, but was president during the Civil War.

Improving test scores may be hurting students’ core knowledge in essential areas.

What do we do about it? Comments are open, of course.

Geography resource links, from a geography pro

December 6, 2007

A professional geographer?

Yeah, they exist — and it’s a booming area. Teachers miss these boats big time, I think, by not getting these professionals into the classroom to show what they do.

Think about it: Geography is a major concern for cellular telephone towers, which are still being constructed by the thousands across the nation. One of the best parts about work at PrimeCo PCS (which became part of Verizon Wireless) was the great sets of maps to work from. Visual data are much more powerful than print on a page; a great secret of PrimeCo’s success was massive use of maps, for the engineers to plan coverage, but also for site acquisition, sales, marketing, and everything else in between.

Consider the use of chips to track shipping palettes; consider the rise in GPS use. Geography is a key player in all transportation and development industries.

So, do your kids know that? Do they know they will be required to be geographically literate — and it can increase their income — when they get a job delivering pizza?

I digress. Here’s a guy, Scott McEachron, with a blog almost-offensively titled 3D – Paving the Way, which he aims to be a resource for users of Autocad 3D. (Oh, so we’re paving the way to using technology, and not laying down concrete and asphalt? Like I said, almost offensive).

His blog has a side bar that shows tremendous, free resources for professional geographers. Can teachers get some use out of these things? Go see: Check the widget titled “Freely Distributed GIS Data.” (Most of the data are free, mostly.)

These are pro resources. They don’t come neatly packaged with suggested lesson plans. You’re going to have to noodle around to see what’s usable in your class, and what is not.

(Dallas teachers? He’s a Dallas guy. Do I sense a guest speaker?)


Student project: Photography + cartography + internet

December 6, 2007

Ignoble Gases nicely describes the mashup between on-line mapping services and digital photography, with a bit of blogging thrown in.

Mapping services now have the capacity to link photographs of a site with its exact latitude and longitude, or exact address.  Maps of cities can feature links to photos of the site (other than satellite or aerial photos) submitted by readers, and other descriptive material.

So, geography teachers:  Have your kids mapped out your town and put it on the web to encourage tourism?  Great discussion topics:  What are the advantages of such technologies, and what are the parent-scaring disadvantages, or dangers of them?

I really cannot do justice to the concepts here — read the article at Ignoble Gases.


New landmarks

December 5, 2007

When a director wants a movie to demonstrate the British government, we get shots of Whitehall and Big Ben. When it’s the U.S. government to be invoked, the U.S. Capitol appears. A quintessential Russia image is the Kremlin. The Eiffel Tower evokes France. High school geography, history and government students should be able to recognize these sorts of landmarks to identify the nation or area in question.What about new landmarks? Brussels probably least penetrates the U.S. psyche of all the major European capitals. It’s a beautiful city, though, and a fun city, in my brief experience. Tradition and modernity mix and intermingle. While I stayed in a modern hotel, I strolled through plazas hundreds of years old. The city is easy to navigate, especially since it seems smaller than London or Paris, and until recently, it was largely unmarked by very tall buildings.

What will the landmarks be of the next 40 or 50 years? Dallas’s skyline shines at night with green neon outlining the city’s tallest building. Several other buildings retrofitted lights in blue, red and white, partly to compete — and of course, there is the red neon Pegasus, the symbol of the old, Dallas-based Magnolia Petroleum Co., which was bought up by Mobil, now a part of Exxon-Mobil. Lights give interesting ways to make new landmarks at night.

Brussels leaped into the bigtime with the recent opening of the Dexia Towers, a building that is lighted on the outside by a series of light-emitting diodes (LEDs) of various colors, at each window of the building. Will this become a hallmark of Brussels?

What other new structures will become common symbols in the next couple of decades?

Doesn’t this photo make you want to go see the thing? 150,000 LEDs can be programmed for elaborate displays. Go see other photos at Room at the Top.
