POTD: Ball Court of Coba

From 2017 01 29 Caribbean Cruise

Today's photo-of-the-day is from the ancient Mayan city of Coba on Mexico's Yucatan peninsula. It shows the ball court. The object of the game was to maneuver a ball, without using your hands, through the stone hoop attached to the side wall of the court. The rules of the game are in dispute (kind of like American football) but that doesn't stop archaeologists from deducing that the losers of the game (or sometimes the winners) were ritually sacrificed (kind of like American politics).

Sand Storm (2016)

IMDB

Sand Storm (2016): Girl meets boy. Dad objects and arranges a different marriage. Then dad brings home a second wife. Age-old story. B+

POTD: Abandoned City of Coba

From 2017 01 29 Caribbean Cruise

Today's photo-of-the-day is from the ancient Mayan city of Coba on Mexico's Yucatan peninsula. It was a huge city but the jungle has mostly reclaimed it.

Bonus photos after the jump.

Lo and Behold (2016)

IMDB

Lo and Behold (2016): History & future of the Internet. Some topics are promising (AI), some scary (solar flares), some badly misjudged. C+

Billy Lynn's Long Halftime Walk (2016)

IMDB

Billy Lynn's Long Halftime Walk (2016): War in Iraq. Pro football in Dallas. A study of PTSD. Flat acting. Clichéd characters. Watchable. C+

As is usually the case, the movie is not as good as the book, which was reviewed here in 2013.

Magnet Schools vs Neighborhood Schools

Five years ago, I blogged about magnet schools — their purpose and their effect. I think it holds up well, in that I had questions about the purpose and effect of magnet schools in Richardson that I couldn't answer then and I still can't answer today. I don't believe there has been adequate public discussion. It's time.

POTD: D'Amico

From 2017 01 29 Caribbean Cruise

Today's photo-of-the-day is from Galveston Bay, the entrance to the busy Houston Ship Channel, ranked first in the United States in foreign waterborne tonnage; first in U.S. imports; and first in U.S. export tonnage.

Local, State, Nation: Same Story

Recently, I posted a graph showing Richardson ISD schools' academic ranking plotted against the percentage of students they have on the free and reduced lunch program. As I expected it showed a correlation — as socio-economic status drops, so too does academic ranking.

From SchoolDigger.com

Today I want to look at state and national data.

Logan Lucky (2017)

Logan Lucky (2017): Redneck Oceans 11, where NASCAR not Vegas is the target. Decent fun if you bring enough suspension of disbelief. B-

Local Evidence that Demography is Destiny

When looking at Schooldigger.com school performance numbers, I fell back on a story of demographics to explain why the Richardson ISD has some of the highest performing schools in the state *and* some of the lowest performing. Same school district. Same policies. Same curriculum. Same central administration. But widely differing results. Different demographics, I said.

I was confident my story wasn't a fairy tale, but I didn't bother backing it up with more than just a couple of quick data points. I believe that it's a good personal habit to challenge one's own preconceptions now and then. Because sometimes I'm wrong. (I know. Hard to believe.) So I did my homework.
