Big Data News Roundup: Correlation vs. Causation - Forbes - 2 views

  •  
    The discussions about "big data" are receiving pushback who believe the conclusions are erroneous. Note that this is tied up in learning analytics as well. "Cuzzillo is joined by a growing chorus of critics that challenge some of the breathless pronouncements of big data enthusiasts. Specifically, it looks like the backlash theme-of-the-month is correlation vs. causation, possibly in reaction to the success of Viktor Mayer-Schönberger and Kenneth Cukier's recent big data book in which they argued for dispensing "with a reliance on causation in favor of correlation""

  •  
    Artificial Intelligence and the "deep learning" movement are hitting it big time: big bucks and big influence on our future. Geoff Hinton is working for Google to help improve voice recognition, image tagging and more. Microsoft, IBM, Baidu (search enging in China) and others are getting into AI. This is part of education as AI and learning tools can be greatly impacted. Read and share this article if you're an education or technology futurist. Fascinating.

The Atlantic Online | January/February 2010 | What Makes a Great Teacher? | Amanda Ripley - 14 views

    "What Makes a Great Teacher? Image credit: Veronika Lukasova Also in our Special Report: National: "How America Can Rise Again" Is the nation in terminal decline? Not necessarily. But securing the future will require fixing a system that has become a joke. Video: "One Nation, On Edge" James Fallows talks to Atlantic editor James Bennet about a uniquely American tradition-cycles of despair followed by triumphant rebirths. Interactive Graphic: "The State of the Union Is ..." ... thrifty, overextended, admired, twitchy, filthy, and clean: the nation in numbers. By Rachael Brown Chart: "The Happiness Index" Times were tough in 2009. But according to a cool Facebook app, people were happier. By Justin Miller On August 25, 2008, two little boys walked into public elementary schools in Southeast Washington, D.C. Both boys were African American fifth-graders. The previous spring, both had tested below grade level in math. One walked into Kimball Elementary School and climbed the stairs to Mr. William Taylor's math classroom, a tidy, powder-blue space in which neither the clocks nor most of the electrical outlets worked. The other walked into a very similar classroom a mile away at Plummer Elementary School. In both schools, more than 80 percent of the children received free or reduced-price lunches. At night, all the children went home to the same urban ecosystem, a zip code in which almost a quarter of the families lived below the poverty line and a police district in which somebody was murdered every week or so. Video: Four teachers in Four different classrooms demonstrate methods that work (Courtesy of Teach for America's video archive, available in February at teachingasleadership.org) At the end of the school year, both little boys took the same standardized test given at all D.C. public schools-not a perfect test of their learning, to be sure, but a relatively objective one (and, it's worth noting, not a very hard one). After a year in Mr. Taylo

Play It Safe: Hackers use the back door to get into your computer; a strong, well-chose... - 0 views

  • For the home user, however, password safety requires more than on-the-fly thinking. Pacheco suggests a system built around a main word for all instances. The distinction is that the name of the site is added somewhere. For example, if the main word is "eggplant," the password might be "eggyyplant" Yahoo, "eggplantgg" for Google or "wleggplant" for Windows Live. He suggests listing the variations in an Excel spreadsheet.
  • Password security is a big deal, and if you don't think it is, then someone might be hacking into your computer even as you read this. A strong password isn't foolproof, but it proves that you're no fool. And it might protect you from compromised data, a broken computer or identity theft. Your bank account, your personal e-mails and lots of other stuff are at risk with weak passwords.
  • "A good password is the most important part of Internet security," said Robert Pacheco, the owner of Computer Techs of San Antonio. "It's the beginning and end of the issue. You can't stop it (hacking). You do what you can do to prevent it. You just try to stop most of it." A strong firewall, as well as spyware -- and virus-detection software -- protect a computer's so-called "back door," Pacheco said, where a hacker can gain access through various cyber threats. Those threats include infected e-mail attachments; phishing Web pages that exploit browser flaws; downloaded songs or pictures with hidden trojans; or plain ol' poking-and-prodding of a computer's shields. But passwords protect information from a frontal assault by way of the computer's keyboard.

  • Other people use easy-to-remember passwords. Trouble is, Rogers said, they're easy-to-guess passwords, too. Good examples of bad passwords are your name, your family's names, your pet's name, the name of your favorite team, your favorite athlete or your favorite anything. Get to know the person -- a technique that geeks refer to as "social engineering" -- and the password is easy to guess. There are message-board stalkers who can guess passwords in a half-dozen tries. Hackers rely on a lot of methods. Some, Rogers said, employ "shoulder surfing." That means what it sounds like -- looking over someone's shoulder as that person is typing in a password.

  • The type of hardware being used can be a clue, said Rogers, a senior technical staffer in the CERT Program, a Web security research center in Carnegie-Mellon University's software engineering institute. It's easy to find a default password, typically in the user's manual on a manufacturer's Web site. If the user hasn't changed the default, that's an easy break-in.

  • Most of the password hacking activity these days goes on at homes, in school or in public settings. These days, many workplaces mandate how a password is picked.
  • The idea is to choose a password that contains at least one uppercase letter, one numeral and at least eight total characters. Symbols are good to throw in the mix, too. Many companies also require that passwords be changed regularly and that pieces of older ones can't be re-used for months. And user names cannot be part of the password. Examples: Eggplant99, 99eggpLanT, --eggp--99Lant. For the next quarter, the password might change to variations on "strawberry.

Fighting Childhood Obesity One School Cafeteria at a Time - ABC News - 0 views

  •  
    Can you design a school to promote healthy eating? There are things every cafeteria can do (read to the end.) This is a big problem and something we need to address. Every school should have a fruit basket near the checkout. It is a no brainer, but do we? "Just walk into the cafeteria and you can see this is no ordinary elementary school. "One of the most striking differences is the openness of the eating space," said pediatrician Dr. Matthew Trowbridge, who also consulted on the project. Students can look into the area where the food is prepared, and they can look outside to a planned school garden, where vegetables will soon be planted."

Can the FCC Create Public Super Wi-Fi Networks? - 0 views

  •  
    No, the government isn't CREATING a WIFI network (the Washington Post didn't really look at this), however, this article on Gizmodo does share what is happening at the FCC that could help many, especially those in rural areas, be part of the world's new digital landscape. As we work to put devices in our student's hands, this sort of development could make a big difference for kids and can further spur online and blended learning initiatives as digital divides are further bridged. Applause? Can we have it next week? "Let's get one thing straight: the government is not creating its own "super WiFi network", but its plans will indeed make awesome new WiFi networks possible. Technically, what the FCC is actually trying to do is increase the amount of open spectrum that is available for WiFi networks of all sorts-and for other "unlicensed" uses. This is a very good idea."

Review: How to teach Secondary Science by @CatrinGreen - 2 views

  •  
    We all remember science lessons from our school days. Whether the lessons were with the more 'characteristic' teachers in the school, or whether you all released the gas taps when the teacher foolishly left the room, we all seemed to miss the link that science is life! And what an opportunity science teachers have in releasing the magic of life to their pupils, answering BIG questions like "Why am I like my parents?", or "What will my life be like in 2050?", or "Why is Pripyat a deserted town?"

Facebook's "Groups for Schools" Is a Walled Garden of Higher Education - 0 views

  •  
    Facebook's group for schools has just been announced. You don't have to be friends with your students to add them to a class group on Facebook. This is only for highered but is a move to become a more formal learning network. Facebook may evolve from a social network to a social and educational network. This is a big deal and colleges should take a look at this.

Why I Love Project Based Learning | Powerful Learning Practice - 0 views

  • It’s not enough for students to learn a bunch of disconnected facts. They need to be able to synthesis them into a comprehensive whole and create something from what they’ve learned. Often they’ll connect them to their lives in ways we could never have imagined.
    • Dave Truss
       
      Love this! Real-life connections contextualize learning and make it meaningful beyond the classroom experience!
  •  
    Often students are interested in things we don't have time to explore in class. This project allows them to do so and reinforces the big idea that the best inquiry begins with high interest.
