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

"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.

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.

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.

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.”
-
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?

Mr. Johnson added that the book’s migration to the digital realm will turn the solitary act of reading — “a direct exchange between author and reader” — into something far more social and suggested that as online chatter about books grows, “the unity of the book will disperse into a multitude of pages and paragraphs vying for Google’s attention.”

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 - 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.
