The good folks at PBS work to provide great resources for teachers, and they’ve got some for Pi Day, as we might expect. In an e-mail, PBS said:

Veterans Day poster for 2016. Look carefully, you’ll see the names of past military engagements in which veterans may have fought, in the background behind the very sharp photo of the head of a bald eagle, our national symbol.
The Allied powers signed a ceasefire agreement with Germany at Rethondes, France, at 11:00 a.m. on November 11, 1918, bringing the war later known as World War I to a close.
President Wilson proclaimed the first Armistice Day the following year on November 11, 1919, with the these words: “To us in America, the reflections of Armistice Day will be filled with solemn pride in the heroism of those who died in the country’s service and with gratitude for the victory, both because of the thing from which it has freed us and because of the opportunity it has given America to show her sympathy with peace and justice in the councils of the nations…” Originally, the celebration included parades and public meetings following a two-minute suspension of business at 11:00 a.m.
Between the world wars, November 11 was commemorated as Armistice Day in the United States, Great Britain, and France. After World War II, the holiday was recognized as a day of tribute to veterans of both wars. Beginning in 1954, the United States designated November 11 as Veterans Day to honor veterans of all U.S. wars. British Commonwealth countries now call the holiday Remembrance Day.
Online holdings of the National Archives and Records Administration (NARA) provide rich sources of information on America’s military, and on veteran’s day. NARA leans to original documents a bit more than the Library of Congress. For Veterans Day 2016, NARA featured an historic photo form 1961:
NARA caption: President John F. Kennedy Lays a Wreath at the Tomb of the Unknown Soldier as part of Veterans Day Remembrances, Arlington National Cemetery, Arlington, Virginia, 11/11/1961 Series: Robert Knudsen White House Photographs, 1/20/1961 – 12/19/1963.

Mary McGlasson teaches economics at Chandler-Gilbert Community College in Arizona.
She makes videos for use in class, and out of class, and by others, on key economic concepts. I’ve used her videos in economics with great results.
Recently she was recognized with a teaching excellence award; she wrote: “The kind folks at the League for Innovations at the Community College asked each Roueche Award recipient to create a 1-minute video, so here it is. Mine’s a bit of a fail, because it’s 1:25… hope they like it anyway!”
Good on Mary McGlasson.
You want to see the real stuff? It’s all there on McGlasson’s YouTube channel. Here are a couple of examples.
Scarcity and Choice
Congratulations to Mary McGlasson — and thanks! Economics teachers, go see what she’s got.
Can you do better? Can you adopt these methods for different subjects? Please try.

Isaac Newton and a friendly bird, on the verge of discovery; still from the film, “Physics,” by Asa Lucander.
History teachers, physics teachers, you should use this film.
In amusing animation — perhaps a throwback to earlier animations, but good and amusing — produced by Åsa Lucander @ 12foot6, for the television Science Club series on BBC2, hosted by Dara O Briain (who does the narration).

For my money, this should be a valuable classroom tool. In four short minutes the film covers most of the really great advances in physics, suitably for world history or U.S. history. It’s clear enough in its presentation that physics students should find it a useful review. Or more likely, they’ll understand what we’ve been trying to teach them, for the first time.
Science gets left out of history courses way too easily. Here’s a quick way to stick it back in.
I had an appointment this afternoon and a friend (a retired ESL teacher) was my substitute. Here was her posting this evening:
“I just had the worst subbing experience ever! I was at a local elementary school doing my ESL thing during the very worst of this afternoon’s hideous rainstorm when the fire alarm went off and we had to evacuate. The fire dept. showed up, of course. Seriously, it was rainfall of Biblical proportions. The asphalt playground was literally ankle deep and it just kept coming down. We were out there for about 8 minutes with absolutely no shelter. When they finally rang the bell, we couldn’t get back in the building because the key cards wouldn’t work. What a fiasco!!! I had no jacket and no umbrella– and neither did most of the kids. Half of them went into total meltdown. I got soaked all the way through every item of clothing on my body. My shoes were sponges. I had to wring out my bra when I got home (no, not exaggerating). This happened around 1:30, so they decided to notify parents that they could either pick up their kids or bring them dry clothes. Oh, shit, what a nightmare.
Why did this happen you ask? Because the roof leaked– which it has apparently been doing for a few years now– into the fire alarm system and set it off. This is what happens when the useless superintendent gets a 30% raise, hires herself a $15,000/mo consultant to sandbag teachers, and then employs a staff of spin doctors to cover her ass instead of fixing schools. I am not a happy camper!”
Good day for an appointment!
Among the lessons, friends (keep passing the loaves and fishes until everyone has had something to eat, please):
No: more testing, no matter how rigorous nor expensive, will not fix this problem; in fact, diverting money from this problem to make zowie-grosso tests is an enormous part of the problem.
Neither opposing the Common Core State Standards, nor imposing those or any other standards will fix the problem.
No, firing the teachers won’t fix the problem — cannot make the roof stop leaking.
This is daily life in classrooms all across America. In Dallas Independent School District, my classroom regularly heated to 90º in August, February, and every other month. My colleague across the the hall had a classroom that stayed at 50º, at the same time. No administrator could fix it, they claimed. I’ve taught in schools where the library roofs leaked, and where classrooms regularly flowed with water in storms. Worse, I’ve been to schools where those problems occurred from the plumbing and sewer hookups. Classrooms where the doors don’t close, or open; where the windows are stuck open, or closed; where the room carefully engineered for 22 students had 36 desks and 40 students; where the electrical outlets sparked a glorious 4th of July salute whenever a student would try to sneak a phone charge.
To make schools work, teachers must be able to work. For teachers to be able to work, we must provide them with all the support that makes any workplace safe, and which makes classrooms comfortable for students and teachers to focus on learning.
Check around your local schools. Are they in peak physical condition? Do all the support systems work? Are the toilets and restrooms clean, working, and safe?
How many tests could fix any of those problems? How many teachers must be fired to get a roof to stop leaking?
Why would we torture our children, instead of letting them learn?
The most effective school, ever. “Aristotle and his pupil Alexander,” engraving by Charles Laplante, a french engraver and illustrator, 1866. Wikimedia image. Note the roof does not leak in this school.
