The role of communities of practice in a digital age - 36 views

  • Wenger argues that there are three crucial characteristics of a community of practice: domain: a common interest that connects and holds together the community community: a community is bound by the shared activities they pursue (for example, meetings, discussions) around their common domain practice: members of a community of practice are practitioners; what they do informs their participation in the community; and what they learn from the community affects what they do.

Dynamic Versus Static Dictionary With and Without Printed Focal Words in E-Book Reading as Facilitator for Word Learning - Korat - 2014 - Reading Research Quarterly - Wiley Online Library - 17 views

  • Four groups read the e-book with a dictionary with (1) static visuals (SVs) without the printed focal words, (2) dynamic visuals (DVs) without the printed focal words, (3) SVs with the printed focal words, or (4) DVs with the printed focal words. The fifth group read the e-book without a dictionary (control). The results show that word explanations and word use progressed the most after reading the e-book with DVs and printed focal words. Less progress was observed when reading with SVs with printed focal words and DVs without printed focal words.

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.
  • 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.
  • n 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 outpo
  • 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.
  • nches below the surface the team struck an elaborately fashioned stone. Then another, and another—a ring of standing pillars.
  • Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth.
  • he 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.
  • They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.
  • 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.
  • Puzzle piled upon puzzle as the excavation continued. For reasons yet unknown, the rings at Göbekli Tepe seem to have regularly lost their power, or at least their charm. Every few decades people buried the pillars and put up new stones—a second, smaller ring, inside the first.
  • he site may have been built, filled in, and built again for centuries.
  • Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.
  • Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.

High School Graduates Feel Unprepared For College and Work, Survey Finds - College Bound - Education Week - 44 views

  • 5. Have an assessment late in high school so students can find out what they need for college (77 percent.)
    • Sharin Tebo
       
      What kind of assessment? I mean, if it is a standardized test, does that really help students prepare for life, whether college-bound or not? 
  • So, how can high schools better serve students and bridge this divide? Respondents' top suggestions for change: 1. Provide opportunities for real-world learning (90 percent);
  • A recent survey of public high school graduates finds about half feel they are unprepared for life after high school and most would have worked harder if they had realized the expectations of college and the workplace.
  •  
    I'm not so sure that I believe that less than 1,500 graduates nationwide over the span of just three graduating classes is exactly representative of all high school grads in America, but at least it was conducted by a nonprofit and not one of our education deformer companies or a textbook publisher. Also, isn't a certain amount of laissez-faire attitude a normal teenage brain condition? "I wish I'd paid more attention in high school" was a major theme of conversation at *my* 20 year high school reunion last year (did I just date myself)  BUT I did feel better prepared in study skills and habits, perhaps because in 1993 we weren't so test-centered. Just sayin' Thanks for sharing!
