Why do so many oil spills happen? - CSMonitor.com - 0 views

    • Jeff Woodcock
       
      hard part
  •  
    "n brief, because there are a lot of tricky steps to get oil from inside the Earth to inside, say, your gas tank. Oil spills can be caused by the accidental or intentional release of any form of petroleum during any point in the oil production process, from drilling, refining, or storing to transporting. Oil can be spilled when a pipeline breaks, ships collide or are grounded (as happened earlier this month along the Great Barrier Reef), underground storage tanks leak, or in the current case, when an oil rig explodes or is damaged. IN PICTURES: Big Environmental Disasters Some oil was spilled when the Deepwater Horizon rig first burst into flames on April 20 in the Gulf, injuring crew members and sending a billowing plume of black smoke into the sky that could be seen by satellite. The oil rig, located about 51 miles (82 kilometers) southeast of Venice, La., then sank into the Gulf waters Thursday morning, creating concern that more oil could spill. Oil spills can also happen naturally: Oil is released into the ocean from natural oil seeps on the seafloor. The best known such seep is Coal Oil Point along the California coast where an estimated 2,000 to 3,000 gallons (7,570 to 11,400 liters) of crude oil is released each day."

    As blended learning continues to expand across the K-12 sector, definitions are important to help people talk about the new phenomena. This white paper refines our previous work in helping to create a shared language for the emerging field so that innovators can build upon each other's ideas, rather than talk past each other.

Lifelong Kindergarten :: MIT Media Lab - 4 views

  •  
    "Crickets are small programmable devices that can make things spin, light up, and play music. You can plug lights, motors, and sensors into a Cricket, then write computer programs to tell them how to react and behave. With Crickets, you can create musical sculptures, interactive jewelry, dancing creatures, and other artistic inventions -- and learn important math, science, and engineering ideas in the process. Crickets are based on more than a decade of NSF-funded educational research. Lifelong Kindergarten researchers collaborated with the LEGO company to create the first "programmable bricks," squeezing computational power into LEGO bricks. This research led to the LEGO MindStorms robotics kits, now used by millions of people around the world. While LEGO MindStorms is designed especially for making robots, Crickets are designed especially for making artistic creations. Crickets were refined in collaboration with the Playful Invention and Exploration (PIE) museum network, and are now sold as a product through the Playful Invention Company (PICO)."

Collaborative Learning with Google Docs - The Learner's Way - 72 views

  •  
    Something is missing from my classroom lately and I am quite happy to have seen it disappear. It is the traditional line at the teacher's desk formed by students awaiting feedback on a recently completed piece of writing. What has replaced this is our use of Google Docs and Slides as a tool for the collaborative development of ideas from initial thinking and strategising through to final editing and refinement. It has introduced a new workflow to the class that both streamlines the process of providing feedback, allows for greater detail and transforms the process into one that is richly collaborative.

Powerful Provocations for Learning: Sparking curiosity and increasing engagement - The ... - 15 views

  •  
    Powerful learning begins with the perfect provocation. Creating, refining and skilfully presenting the perfect provocation is an essential capability for teachers hoping to engage their class in rich dialogue. Claims that the percentage of students engaged by their learning declines from 75 percent in fifth grade to 32 percent by eleventh grade suggests a need for a more provocative environment.

Reintroducing students to Research - 144 views

  • First, we think research, broadly defined, is a valuable part of an undergraduate education. Even at a rudimentary level, engaging in research implicates students in the creation of knowledge. They need to understand that knowledge isn’t an inert substance they passively receive, but is continually created, debated, and reformulated—and they have a role to play in that process.
  • we recognize that research is situated in disciplinary frameworks and needs to be addressed in terms of distinct research traditions.
  • research is a complex and recursive process involving not just finding information but framing and refining a question, perhaps gathering primary data through field or lab work, choosing and evaluating appropriate evidence, negotiating different viewpoints, and composing some kind of response, all activities that are not linear but intertwined.

  • learning to conduct inquiry is itself complex and recursive. These skills need to be developed throughout a research project and throughout a student’s education.
  • the hybrid nature of libraries today requires students to master both traditional and emerging information formats, but the skills that students need to conduct effective inquiry—for example, those mentioned in your mission statement of reading critically and reasoning analytically—are the same whether the materials they use are in print or electronic.
  • Too often, traditional research paper assignments defeat their own purpose by implying that research is not discovery, but rather a report on what someone else has already discovered. More than once I’ve had to talk students out of abandoning a paper topic because, to their dismay, they find out it’s original. If they can’t find a source that says for them exactly what they want to say—better yet, five sources—they think they’ll get in trouble.
  • In reality, students doing researched writing typically spend a huge percentage of their time mapping out the research area before they can focus their research question. This is perfectly legitimate, though they often feel they’re spinning wheels. They have to do a good bit of reading before they really know what they’re looking for.
  • she has students seek out both primary and secondary sources, make choices among them, and develop some conclusions in presentations that are far from standard literary criticism. One lab focuses on collecting and seeking relationships among assigned literary texts and other primary sources from the second half of the twentieth century to illuminate American society in that time period.
  • For this lab, groups of students must find ten primary sources that relate in some way to literary texts under discussion and then—here’s the unusual bit—write three new verses of “America the Beautiful” that use the primary sources to illuminate a vision of American society. Instead of amber waves of grain and alabaster cities, they select images that reformulate the form of the song to represent another vision of the country. At the end of the course, her final essay assignment calls upon all of the work the previous labs have done, asking students to apply the skills they’ve practiced through the semester. While students in this course don’t do a single, big research project, they practice skills that will prepare them to do more sophisticated work later.

An Introduction to Design Thinking (Part Two) - 115 views

  •  
    In the constructivist-learning model, engagement and experience combine with immersive environments and self-organisation of knowledge to establish a context in which learning occurs naturally. Constructivism has since the time of Dewey become closely affiliated with Project Based Learning and yet despite years of efforts to refine the process the result does not always match the promise. Design thinking might be the answer.

The beauty of unfinished work - The Learner's Way - 34 views

      The down side of this is that there also has to be some sort of focus on the importance of completing what is started.  Everything might not have to have an end product but some things certainly should have!
  • At times it has been deeply admonished and hidden from view. Individuals who failed were to be shunned or punished. At other times failure was to be avoided by setting the bar for success so low that failure was impossible. The result of this movement was that success became meaningless, achievable by all without risk and through little effort.

      The generation when who were deeply admonished and hidden is older and most are relieved that this is no longer the case.  The generation who were shunned or punished seem to still be a part of the mainstream but most have embraced that this is no longer the case.  The generation who were part of the low expectations with failure impossible seem to be the predominance of the population now and we are seeing that there is no concept of consequences, no motivation toward high achievement, and an attitude of entitlement.

Reading and the Web - Texts Without Context - NYTimes.com - 49 views

  • It’s also a question, as Mr. Lanier, 49, astutely points out in his new book, “You Are Not a Gadget,” of how online collectivism, social networking and popular software designs are changing the way people think and process information, a question of what becomes of originality and imagination in a world that prizes “metaness” and regards the mash-up as “more important than the sources who were mashed.”
    • Stan Golanka
       
      Core discussion topic? From this, I see a few discussion issues: 1. Do we prize "mash-ups" more than original work? Who is "we" in this? 2. If the answer to #1 is "yes," then the next question is: is this good or bad? 3. Finally, if the answer is "bad" to #2, what place do "mash-ups" have, and how do we help our students see the value in original work?

    • Stan Golanka

  • Instead of reading an entire news article, watching an entire television show or listening to an entire speech, growing numbers of people are happy to jump to the summary, the video clip, the sound bite — never mind if context and nuance are lost in the process; never mind if it’s our emotions, more than our sense of reason, that are engaged; never mind if statements haven’t been properly vetted and sourced.
    • Stan Golanka
       
      Should teachers "fight" this, or embrace it? Can summaries/sound bites ever be appropriate for academic discussions?
  • And online research enables scholars to power-search for nuggets of information that might support their theses, saving them the time of wading through stacks of material that might prove marginal but that might have also prompted them to reconsider or refine their original thinking.
  • Digital insiders like Mr. Lanier and Paulina Borsook, the author of the book “Cyberselfish,” have noted the easily distracted, adolescent quality of much of cyberculture.

Princeton University - Kindle pilot results highlight possibilities for paper reduction - 20 views

  • However, e-readers must be significantly improved to have the same value in a teaching environment as traditional paper texts, participants said.
  • but they also said the ability to highlight directly on traditional text, to take notes and flip pages for ease in navigation suffers in the e-reader.
  • With hopes of assisting industry with the refinement of e-readers, and providing useful information to other academic institutions considering the devices, information and data from the one-time pilot have been compiled on an Office of Information Technology (OIT) website.
  • ...5 more annotations...
  • About 65 percent of the participants in the pilot said they would not buy another e-reader now if theirs was broken. Almost all the participants said they were interested in following the technology to its next stages, because they think a device that works well in academia would be worth having.
  • "I found the device difficult to use and not conducive to academic purposes," he said, and added, "But I can see how it can be used for pleasure reading."
  • What they liked best about the devices was: the battery life, the wireless connection and the portability of the e-reader; the fact that all the course reading was on one device; the ability to search for content; and the legibility of the screen, including the fact it could be read in full sunlight. The top five suggestions students had for improving e-readers were: improving the ability to highlight and annotate PDF files; improving the annotation tools; providing a folder structure to keep similar readings together; improving the highlighting function; and improving the navigation within and between documents on the reader (including having more than one document open at the same time for comparison).
  • "The Kindle would be better for an academic setting if the PDF format worked more effectively,"
  • "There would be a greater benefit realized if the devices could develop a better way to deliver the ubiquitous PDF document, which is used by many journals and libraries to deliver documents, and is the common format in which dissertations and theses are published and read by faculty," Temos said. "Some students said they spent a considerable amount of time printing PDF documents during the semester, and hardly ever referred back to them once the semester was over. I don't expect that is unusual."

Educational Leadership:How Teachers Learn:Learning with Blogs and Wikis - 57 views

  • Bloggers spend significant time pushing their own thinking—and having their thinking pushed by others. They respond to comments and link to other writers, connecting to and creating interesting ideas. Some develop curriculum and instructional materials together. Others review resources and debate the merits of the individual tools of teaching. Philosophical conversations about what works in schools are common as teachers talk about everything from homework and grading practices to school and district policies that affect teaching and learning. Blogs become a forum for public articulation—and public articulation is essential for educators interested in refining and revising their thinking about teaching and learning.

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

      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.
