Thumbs in Eyes, Kids in Schools

By J.F., The Economist

Thomas Perez - Department of Justice

ON TUESDAY Thomas Perez, assistant attorney general for the Justice Department’s civil-rights division, sent a letter to the superintendents of Alabama’s school districts. HB56, Alabama’s harsh immigration law, requires “public schools to determine the citizenship and immigration status of students enrolling.” Supporters insist that this information will only be used to compile statistics. Latinos in Alabama, you will not be surprised to hear, are not convinced: school districts seem to be losing Hispanic students. Mr Perez wrote that HB56 “may chill or discourage student participation in, or lead to the exclusion of school-age children from, public education programmes based on their parents’ race, national origin, or actual or perceived immigration status… In Plyler v Doe, the Supreme Court held that a state may not deny a child equal access to public education based on his or her immigration status.” Mr Perez has asked for a list of all students enrolled in the state’s public schools on September 27th (the day before a federal judge in Birmingham allowed most of the law to take effect), and all students who have withdrawn or had at least one unexplained absence since that date. He has asked for the information to be delivered by November 14th, and then by the 15th of every month thereafter. So score one for all lovers of list collection, government bureaucracy and vigorous federal oversight.

As it happens, the lessons of Plyler are not restricted to the intersection of immigration and education. In 1982, the Supreme Court ruled 5-4 that school districts could not deny a free public education to children in the United States unlawfully, meaning they could neither exclude them nor charge them tuition that they did not charge other students. They justified this decision using the equal protection clause of the Fourteenth Amendment, which says that states cannot “deny to any person within its jurisdiction the equal protection of the laws.” Attorneys for the Texas school district in question tried to argue that illegal immigrants were not “persons within the jurisdiction of the State of Texas”; the Court rightly scoffed at that (one suspects that illegal immigrants who committed a crime would swiftly find out what jurisdiction they were in). The court pointed out that the Fourteenth Amendment’s protections are explicitly not limited to citizens. Precedent established in an 1886 case (Yick Wo v Hopkins) held that the promises of equal protection “are universal in their application, to all persons within the territorial jurisdiction without regard to any differences of race, of colour, or of nationality; and the equal protection of the laws is a pledge of the protection of equal laws.” In other words, the Fourteenth Amendment—and, extrapolating from the final clause of the above sentences, the constitution itself—is not a just set of rights granted to American citizens; it is at its heart a set of limits imposed upon governments, states as well as federal.

Pure Genius

By Julian Baggini, in Financial Times

At the age of 14, in 1846, James Clark Maxwell published his first scientific paper in a learned journal, having already seen his poetry printed in the Edinburgh Courant. In 1864, he went on to write the classic A Dynamical Theory of the Electromagnetic Field, which gave a unified account of electricity, magnetism and light in just four equations. Einstein later remarked that he stood on the shoulders of not Newton but Maxwell.

Almost everyone would agree that Maxwell was a genius. But what exactly does this mean? In the popular imagination, geniuses are a breed apart. They are capable of insights or artistic creations that no amount of training and effort could produce in mere ordinary folk. You can squander your genius or fail to fulfil it but, ultimately, you either have it at birth or you don’t.

$3.4 Billion is Left in Race to Top Aid

From Lesli A. Maxwell and Michele McNeil, in Education Week

By selecting just two states as first-round Race to the Top winners, U.S. Secretary of Education Arne Duncan is leaving $3.4 billion on the table for the remaining states to vie for in round two.

Delaware and Tennessee beat out 14 other finalists last week to win the first grants awarded in the $4 billion Race to the Top Fund competition.

Mr. Duncan praised the two states, which edged out front-runners Florida and Louisiana, for mustering strong district and teachers’-union support for their plans, for having superior data systems, and for submitting comprehensive proposals that touched “every single child” statewide.

g, a Statistical Myth

From Three-Toed Sloth: Slow Takes from the Canopy (My Very Own Internet Tradition)

Anyone who wanders into the bleak and monotonous desert of IQ and the nature-vs-nurture dispute eventually gets trapped in the especially arid question of what, if anything, g, the supposed general factor of intelligence, tells us about these matters. By calling g a “statistical myth” before, I made clear my conclusion, but none of my reasoning. This topic being what it is, I hardly expect this will change anyone’s mind, but I feel a duty to explain myself.

To summarize what follows below (“shorter sloth”, as it were), the case for g rests on a statistical technique, factor analysis, which works solely on correlations between tests. Factor analysis is handy for summarizing data, but can’t tell us where the correlations came from; it always says that there is a general factor whenever there are only positive correlations. The appearance of g is a trivial reflection of that correlation structure. A clear example, known since 1916, shows that factor analysis can give the appearance of a general factor when there are actually many thousands of completely independent and equally strong causes at work. Heritability doesn’t distinguish these alternatives either. Exploratory factor analysis being no good at discovering causal structure, it provides no support for the reality of g.

Building a Better Teacher

07teachers-t_span-articlelarge From Elizabeth Green in the New York Times Magazine:

ON A WINTER DAY five years ago, Doug Lemov realized he had a problem. After a successful career as a teacher, a principal and a charter-school founder, he was working as a consultant, hired by troubled schools eager — desperate, in some cases — for Lemov to tell them what to do to get better. There was no shortage of prescriptions at the time for how to cure the poor performance that plagued so many American schools. Proponents of No Child Left Behind saw standardized testing as a solution. President Bush also championed a billion-dollar program to encourage schools to adopt reading curriculums with an emphasis on phonics. Others argued for smaller classes or more parental involvement or more state financing.

But what makes a good teacher? There have been many quests for the one essential trait, and they have all come up empty-handed. Among the factors that do not predict whether a teacher will succeed: a graduate-school degree, a high score on the SAT, an extroverted personality, politeness, confidence, warmth, enthusiasm and having passed the teacher-certification exam on the first try. When Bill Gates announced recently that his foundation was investing millions in a project to improve teaching quality in the United States, he added a rueful caveat. “Unfortunately, it seems the field doesn’t have a clear view of what characterizes good teaching,” Gates said. “I’m personally very curious.”

When Doug Lemov conducted his own search for those magical ingredients, he noticed something about most successful teachers that he hadn’t expected to find: what looked like natural-born genius was often deliberate technique in disguise. “Stand still when you’re giving directions,” a teacher at a Boston school told him. In other words, don’t do two things at once. Lemov tried it, and suddenly, he had to ask students to take out their homework only once.

It was the tiniest decision, but what was teaching if not a series of bite-size moves just like that?

Many Education Programs Get Boost in Obama’s Budget Proposal

From The Forum on the Future of Public Education

In the education portion of the State of the Union speech, Obama emphasized incentivizing success and reaffirmed his committment to community colleges.  He also outlined a number of financial aid reforms, including a $10,000 tax credit and limits on the percentage of a worker’s income that must go towards repaying students loans.  He set a goal of renewing ESEA, but some experts are skeptical that it can be accomplished this year given the amount of discord NCLB has generated.

Your Brain’s Got Game

From Sujata Gupta, in ScienceNOW Daily News

201012041Always stunk at video games? Perhaps you’ve been cursed with a small striatum, a region of the brain involved in learning and memory. Researchers have found that college students with relatively large striatums learned how to play a challenging video game faster than their small-striatum peers. Large-striatum individuals were also better at shifting priorities from, say, shooting a target to outrunning an enemy–abilities that could translate to the real world.

The game isn’t exactly Halo or Assassin’s Creed. Instead, Space Fortress looks a lot like the very first arcade games, with geometric shapes subbing for spaceships and buildings. “The graphics stink,” admits Arthur Kramer, a psychologist at the University of Illinois, Urbana-Champaign, who designed the game in the early 1980s. Gameplay is fairly complex, however: Players must shoot down a fortress with their ship while avoiding enemies, the bad guys look a lot like the good guys, and the ship has no brakes.

Over the years, researchers have used the game to study memory, motor control, and learning speed. The U.S. Air Force and the Israeli air force have even changed their training regimens based on how cadets fared as players. Recent studies have suggested that players appear to heavily utilize their striatum during gameplay. So Kramer and Kirk Erickson, a psychologist at the University of Pittsburgh in Pennsylvania, decided to investigate whether the size of the striatum alone might be responsible for these abilities.

Building a Nation of Tinkerers: Digital Media Fosters Hands-On Learning in Science Labs

From Josh Karp in Spotlight on Digital Media and Learning

lab-365x2431

Digital media can extend the goals of National Lab Day and help the United States rebuild its lead in science and math.

And it’s the love of that process that Hidary and the Obama administration are hoping to instill in school children with National Lab Day, a nationwide effort to provide support and opportunities for kids to learn science, technology, engineering and math (STEM) through “hands on” application, rather than in the world of Bunsen burners and books with titles like “Laboratory Procedures.” The underlying idea, according to Obama, is to encourage American kids to be “makers of things, not just consumers of things.”

“It was clear to me that the facts I’d accumulated weren’t what was important,” says Hidary, a successful finance and tech entrepreneur who established his own foundation in 2001 to promote sustainable development and apply market forces to social issues. Instead, he found, the more important factor was his experience with “the process of discovery.”

During a fellowship in neuroscience at the National Institute of Health, it struck Jack Hidary that the facts he’d learned during a lifetime of classroom science education mattered less than the basic lessons he’d learned tinkering around on his own as a kid.

U.S. Common-Standards Push Bares Unsettled Issues: Familiar Themes Emerge in Resurgent Debate

From Sean Cavanagh in Education Week

It is one of the simplest ideas in American education—and one of the most confounding: Elected officials and educators have been talking about establishing national, or common, academic standards for at least a half-century.

On its face, the logic of that goal seems incontrovertible.

Why should students in one state be introduced to a topic such as fractions as 1st graders, to cite a common example, when their peers in other states won’t cover that mathematics topic until later? More broadly, why does the United States—a mobile society in a globally competitive era—maintain an education system that tests students, trains teachers, and churns out textbooks and classroom materials based on the myriad and often idiosyncratic demands of different states?
