J. Michael Shaughnessy, president of the National Council of Teachers of Mathematics, argues that the latest PISA test "underscores the need for integrating reasoning and sense making in our teaching of mathematics." Randi Weingarten, head of the American Federation of Teachers, claims that the same results "tell us … that if you don't make smart investments in teachers, respect them, or involve them in decision-making, as the top-performing countries do, students pay a price."

But don't expect any of them to bring the country back to its educational golden age -- there wasn't one.

According to the most recent statistics, the U.S. share of foreign students fell from 24 percent in 2000 to just below 19 percent in 2008. Meanwhile, countries like Australia, Canada, and Japan saw increased market shares from their 2000 levels, though they are still far below the American numbers.

And even with its declining share, the United States still commands 9 percentage points more of the market than its nearest competitor, Britain.

A 2008 Rand Corp. report found that nearly two-thirds of the most highly cited articles in science and technology come from the United States, and seven in 10 Nobel Prize winners are employed by American universities. And the United States spends about 2.9 percent of its GDP on postsecondary education, about twice the percentage spent by China, the European Union, and Japan in 2006.

But over the long term, exactly where countries sit in the university hierarchy will be less and less relevant, as Americans' understanding of who is "us" and who is "them" gradually changes. Already, a historically unprecedented level of student and faculty mobility has become a defining characteristic of global higher education. Cross-border scientific collaboration, as measured by the volume of publications by co-authors from different countries, has more than doubled in two decades.

The Children's Online Privacy Protection Act of 1998 (COPPA) applies to the online collection of personal information by persons or entities under U.S. jurisdiction from children under 13 years of age.

In the 1960s archaeologists from the University of Chicago had surveyed the region and concluded that Göbekli Tepe was of little interest. Disturbance was evident at the top of the hill, but they attributed it to the activities of a Byzantine-era military outpost.

Schmidt had come across the Chicago researchers' brief description of the hilltop and decided to check it out. On the ground he saw flint chips—huge numbers of them. "Within minutes of getting there," Schmidt says, he realized that he was looking at a place where scores or even hundreds of people had worked in millennia past.

s the months and years went by, Schmidt's team

found a second circle of stones, then a third, and then more. Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth

The pillars were big—the tallest are 18 feet in height and weigh 16 tons. Swarming over their surfaces was a menagerie of animal bas-reliefs, each in a different style, some roughly rendered, a few as refined and symbolic as Byzantine art.

The circles follow a common design. All are made from limestone pillars shaped like giant spikes or capital T's. Bladelike, the pillars are easily five times as wide as they are deep. They stand an arm span or more apart, interconnected by low stone walls. In the middle of each ring are two taller pillars, their thin ends mounted in shallow grooves cut into the floor.

"They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.

To Schmidt, the T-shaped pillars are stylized human beings, an idea bolstered by the carved arms that angle from the "shoulders" of some pillars, hands reaching toward their loincloth-draped bellies.

The stones face the center of the circle—as at "a meeting or dance," Schmidt says—a representation, perhaps, of a religious ritual.

As for the prancing, leaping animals on the figures, he noted that they are mostly deadly creatures: stinging scorpions, charging boars, ferocious lions. The figures represented by the pillars may be guarded by them, or appeasing them, or incorporating them as totems.

The site may have been built, filled in, and built again for centuries.

Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.

The earliest rings are the biggest and most sophisticated, technically and artistically. As time went by, the pillars became smaller, simpler, and were mounted with less and less care. Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.

Increasingly, undergraduates are not prepared adequately in any academic area but often arrive with strong convictions about their abilities.

It has become difficult to give students honest feedback.

As the college-age population declines, many tuition-driven institutions struggle to find enough paying customers to balance their budgets. That makes it necessary to recruit even more unprepared students, who then must be retained, shifting the burden for academic success away from the student and on to the teacher.

Although a lot of emphasis is placed on research on the tenure track, most faculty members are not on that track and are retained on the basis of what students think of them.

Students gravitate to lenient professors and to courses that are reputedly easy, particularly in general education.

It is impossible to maintain high expectations for long unless everyone holds the line in all comparable courses—and we face strong incentives not to do that.

Formerly, full-time, tenured faculty members with terminal degrees and long-term ties to the institution did most of the teaching. Such faculty members not only were free to grade honestly and teach with conviction but also had a deep understanding of the curriculum, their colleagues, and the institutional mission. Now undergraduate teaching relies primarily on graduate students and transient, part-time instructors on short-term contracts who teach at multiple institutions and whose performance is judged almost entirely by student-satisfaction surveys.

Contingent faculty members, who are paid so little, routinely teach course loads that are impossible to sustain without cutting a lot of corners.

Many colleges are now so packed with transient teachers, and multitasking faculty-administrators, that it is impossible to maintain some kind of logical development in the sequencing of courses.

Students may be enjoying high self-esteem, but college teachers seem to be suffering from a lack of self-confidence.

Even if it were true that today visual communication overwhelms written communication, the problem is not to oppose written to visual communication. The problem is how to improve both.

Less clear, though, is whether COPPA covers information such as IP (internet protocol) address, device identification number, the type of browser being used, or other so-called metadata that can often be used to identify users.

some school lawyers have taken the FTC’s previous guidance to mean that their districts must get consent from every single parent, for every single product that collects information online from young children.

First, according to the FTC, schools can grant consent on behalf of parents only when the operator of the website, online service, or app in question is providing a service that is “solely for the benefit of students and the school system” and is specific to “the educational context.”

How are schools supposed to determine if a website or app is strictly educational?

will any information collected from children under 13 be used or shared for commercial purposes unrelated to education? Are schools allowed to review the information collected on students? Can schools request that student info be deleted? If the answers to that second group of questions are, respectively, yes, no, or no, schools are not allowed to grant consent on behalf of parents, according to the FTC.

Many vendors also allow third-party trackers (usually related to analytics or advertising) to be embedded into their sites and services.

How do schools notify parents and get their consent under COPPA?

Often through an Acceptable Use Policy or similar document that is sent home to parents at the beginning of the school year, said Fitzgerald of Common Sense Media.

Even better, Fitzgerald said, is when schools provide a detailed list of exactly what websites/online services/apps students will be using, and what the information practices of each are.

responsibility for deciding “whether a particular site’s or service’s information practices are appropriate” not be delegated to teachers.

Many districts do in fact have that kind of review-and-approval process.
