Intel: Light beams can replace electronic signals for future computers - SmartPlanet - 12 views

shared by Dallas McPheeters on 28 Jul 10 - Cached
  • Here’s how it works, step by step: The transmitter chip is made of four hybrid silicon lasers. Light beams from the lasers each travel into an optical modulator. The modulator encodes data onto the beams at 12.5Gbps. The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors. The photo detectors convert data back into electrical signals.

  • Compared to us, I believe their brains have developed differently," says Sheehy. "If we teach them the way we were taught, we're not serving them well."

      Whether their brains have developed differently or not, we still need to teach our students differently than we were taught. They are living in different times with different demands and expectations. If we teach to the demands and expectations of our childhood would not meet our students needs.
  • children were much more likely to have connections between brain regions close together while older subjects were more likely to feature links between parts of the brain that are physically farther apart.

  • Recent reports from the Pew Internet and American Life Project show that 93 percent of youth ages 12 to 17 go online. Of those kids, 55 percent use social-networking sites (like Facebook and MySpace), and 64 percent are creating their own original content (such as blogs and wikis)

      Is this all happening outside of the classroom?
  • Unlike watching television, using the Internet allows young people to take an active role; this move from consumption to participation affects the way they construct knowledge, develop their identity, and communicate with others.
  • "Computers give you different ways to solve problems, the opportunity to run and test simulations, and a way to offload processing. . . . We need kids to think about problems in innovative and creative ways. We need to change the emphasis of education to focus on higher-order kinds of thinking."
  • "It's a shift from how to memorize and retrieve data in one's mind to how to search for and evaluate information out in the world
  • Even if we're duplicating a real-life scenario in a virtual environment, the fact that students are engaged with technology and performing through a semblance of anonymity lends itself to a deeper level of discourse.
    • Tony Baldasaro

      Why do we need anonymity to get to a deeper level of discourse?
  • "If we fail to do so, our kids are going to look at what they're learning in schools and see that it is irrelevant to the future they see before them."
  • Davis says today's teachers are seeking information when they need it instead of waiting for more formal professional development workshops.

  • only a small proportion of those surveyed are using technology such as virtual-research environments, social bookmarking, data and text mining, wikis, blogs and RSS-feed alerts in their work. This contrasts with the fact that many respondents professed to finding technological tools valuable.Just under half of those polled used RSS feeds and only about 10 per cent used social bookmarking, with Generation Y students exhibiting the same behaviour as other age groups.

teaching digital writing

shared by Gerald Carey on 01 Apr 11 - No Cached
  • These days, pen-and-paper and word-processing skills are not enough to fully prepare students for writing beyond K-12. Students also need direct instruction in digital writing—or writing created or read on a computer or other Internet-connected device. Digital writing requires both traditional writing skills—knowledge of the process, conventions, organizational structure, etc.—and more advanced techniques, such as the ability to meld visual, audio, and text into a single piece.

shared by Ed Webb on 15 Mar 10 - Cached
  • Students in Howard Rheingold’s journalism class at Stanford recently teamed up with NewsTrust, a nonprofit Web site that enables people to review and rate news articles for their level of quality, in a search for lousy journalism.
  • the News Hunt is a way of getting young journalists to critically examine the work of professionals. For Rheingold, an influential writer and thinker about the online world and the man credited with coining the phrase “virtual community,” it’s all about teaching them “crap detection.”
  • last year Rheingold wrote an important essay about the topic for the San Francisco Chronicle’s Web site
  • ...3 more annotations...
  • What’s at stake is no less than the quality of the information available in our society, and our collective ability to evaluate its accuracy and value. “Are we going to have a world filled with people who pass along urban legends and hoaxes?” Rheingold said, “or are people going to educate themselves about these tools [for crap detection] so we will have collective intelligence instead of misinformation, spam, urban legends, and hoaxes?”
  • I previously called fact-checking “one of the great American pastimes of the Internet age.” But, as Rheingold noted, the opposite is also true: the manufacture and promotion of bullshit is endemic. One couldn’t exist without the other. That makes Rheingold’s essay, his recent experiment with NewsTrust, and his wiki of online critical-thinking tools” essential reading for journalists. (He’s also writing a book about this topic.)
  • I believe if we want kids to succeed online, the biggest danger is not porn or predators—the biggest danger is them not being able to distinguish truth from carefully manufactured misinformation or bullshit

  • Augmentation/Apply: Using a simple yet powerful tool for visualization like GeoGebra, students explore the concepts covered in the resources described in 1., and solve related standard problems. The scope and number of the problems is not governed by what is available in the “back of the book,” but rather driven by the evolution of student understanding, as measured by suitable formative assessment processes.
  • Substitution/Remember: Students use ebooks and other Open Education Resources to acquire basic knowledge about statistical tools and procedures. 2. Substitution/Understand: At the same time, they begin a process of gathering information online describing applications of these statistical tools to an area of interest to them, using simple bookmark aggregation services (e.g., Diigo, Delicious) to collect and tag these resources, relating them to the knowledge gained in 1.
