The real economics of massive online courses (essay) | Inside Higher Ed - 2 views

  • Is there a model out there, or an institution/student mix that could effectively utilize MOOCs in such a way as to get around this flaw? It’s hard to tell. Recent articles on Inside Higher Ed have suggested that distance education providers (like the University of Maryland’s University College – UMUC) may opt to certify the MOOCs that come out of these elite schools and bake them into their own online programs. Others suggest that MOOCs could be certified by other schools and embedded in prior learning portfolios.
  • The fatal flaw that I referred to earlier is pretty apparent:  the very notions of "mass, open" and selectivity just don’t lend themselves to a workable model that benefits both institutions and students. Our higher education system needs MOOCs to provide credentials in order for students to find it worthwhile to invest the effort, yet colleges can’t afford to provide MOOC credentials without sacrificing prestige, giving up control of the quality of the students who take their courses and running the risk of eventually diluting the value of their education brand in the eyes of the labor market.
  • In other words, as economists tell us, students themselves are an important input to education. The fact that no school uses a lottery system to determine who gets in means that determining who gets in matters a great deal to these schools, because it helps them control quality and head off the adverse effects of unqualified students either dropping out or performing poorly in career positions. For individual institutions, obtaining high quality inputs works to optimize the school’s objective function, which is maximizing prestige.

  • We also know that there are plenty of low- to no-cost learning options available to people on a daily basis, from books on nearly every academic topic at the local library and on-the-job experience, to the television programming on the National Geographic, History and Discovery channels. If learning can and does take place everywhere, there has to be a specific reason that people would be willing to spend tens of thousands of dollars and several years of their life to get it from one particular source like a college. There is, of course, and again it’s the credential, because no matter how many years I spend diligently tuned to the History Channel, I’m simply not going to get a job as a high-school history teacher with “television watching” as the core of my resume, even if I both learned and retained far more information than I ever could have in a series of college history classes.

Göbekli Tepe -National Geographic Magazine--"Origin of Religion" - 36 views

    • James Spagnoletti
       
      Very cool photographs--take a look.  You will be doing your first art/artifact case studies this week. 
  • Most of the world's great religious centers, past and present, have been destinations for pilgrimages
  • Göbekli Tepe may be the first of all of them, the beginning of a pattern. What it suggests, at least to the archaeologists working there, is that the human sense of the sacred—and the human love of a good spectacle—may have given rise to civilization itself.

  • 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.

Göbekli Tepe - Pictures, More From National Geographic Magazine - 67 views

  • The Birth of ReligionWe used to think agriculture gave rise to cities and later to writing, art, and religion. Now the world’s oldest temple suggests the urge to worship sparked civilization.
  • Before them are dozens of massive stone pillars arranged into a set of rings, one mashed up against the next. Known as Göbekli Tepe (pronounced Guh-behk-LEE TEH-peh), the site is vaguely reminiscent of Stonehenge, except that Göbekli Tepe was built much earlier and is made not from roughly hewn blocks but from cleanly carved limestone pillars splashed with bas-reliefs of animals—a cavalcade of gazelles, snakes, foxes, scorpions, and ferocious wild boars. The assemblage was built some 11,600 years ago, seven millennia before the Great Pyramid of Giza. It contains the oldest known temple. Indeed, Göbekli Tepe is the oldest known example of monumental architecture—the first structure human beings put together that was bigger and more complicated than a hut. When these pillars were erected, so far as we know, nothing of comparable scale existed in the world.
  • At the time of Göbekli Tepe's construction much of the human race lived in small nomadic bands that survived by foraging for plants and hunting wild animals. Construction of the site would have required more people coming together in one place than had likely occurred before. Amazingly, the temple's builders were able to cut, shape, and transport 16-ton stones hundreds of feet despite having no wheels or beasts of burden. The pilgrims who came to Göbekli Tepe lived in a world without writing, metal, or pottery; to those approaching the temple from below, its pillars must have loomed overhead like rigid giants, the animals on the stones shivering in the firelight—emissaries from a spiritual world that the human mind may have only begun to envision.

  • Archaeologists are still excavating Göbekli Tepe and debating its meaning. What they do know is that the site is the most significant in a volley of unexpected findings that have overturned earlier ideas about our species' deep past. Just 20 years ago most researchers believed they knew the time, place, and rough sequence of the Neolithic Revolution—the critical transition that resulted in the birth of agriculture, taking Homo sapiens from scattered groups of hunter-gatherers to farming villages and from there to technologically sophisticated societies with great temples and towers and kings and priests who directed the labor of their subjects and recorded their feats in written form. But in recent years multiple new discoveries, Göbekli Tepe preeminent among them, have begun forcing archaeologists to reconsider. At first the Neolithic Revolution was viewed as a single event—a sudden flash of genius—that occurred in a single location, Mesopotamia, between the Tigris and Euphrates Rivers in what is now southern Iraq, then spread to India, Europe, and beyond. Most archaeologists believed this sudden blossoming of civilization was driven largely by environmental changes: a gradual warming as the Ice Age ended that allowed some people to begin cultivating plants and herding animals in abundance. The new research suggests that the "revolution" was actually carried out by many hands across a huge area and over thousands of years. And it may have been driven not by the environment but by something else entirely.

The Virgin Mary - National Geographic Magazine - 31 views

  • t’s apparition time: 5:40 p.m. In a small Roman Catholic chapel in Bosnia and Herzegovina, in the village of Medjugorje, Ivan Dragicevic walks down the aisle, kneels in front of the altar, bows his head for a moment, and then, smiling, lifts his gaze heavenward. He begins to whisper, listens intently, whispers again, and doesn’t blink for ten minutes. His daily conversation with the Virgin Mary has begun.
