The Perils of Classifying Social Media Platforms as Public Utilities | Mercatus - 1 views

  •  
    Social Media are not essential facilities. Those who claim that Facebook is a "social utility" or "social commons" must admit that such sites are not essential to survival, economic success, or online life. Unlike water and electricity, life can go on without social networking services.

When the Internet Thinks It Knows You - NYTimes.com - 1 views

  • As a result, they’re racing to offer personalized filters that show us the Internet that they think we want to see. These filters, in effect, control and limit the information that reaches our screens.
  • the engineers who write the new gatekeeping code have enormous power to determine what we know about the world. But unlike the best of the old gatekeepers, they don’t see themselves as keepers of the public trust. There is no algorithmic equivalent to journalistic ethics.
  • We citizens need to uphold our end, too — developing the “filter literacy” needed to use these tools well and demanding content that broadens our horizons even when it’s uncomfortable.

NYU Professor Catches 20% Of His Students Cheating, And He's The One Who Pays For It R... - 6 views

  •  
    Interesting case of instructor getting a low SRDP after he tells class he has identified plagiarism. He suggests peer review instead Turnitin.
  •  
    I think it's all how you approach it. Andrew and I have both caught students plagiarizing before we handled those issues privately. It never affected our ratings from the other students because they never knew that it happened. From the professor's blog post and response to this article, it sounds like he did a public witch hunt. Have you caught students cheating before? How did you handle the issue?
  •  
    I would agree with you about privacy, but if enough students are caught in one incident, word will get around. Ironically, all of the incidents I had to deal with were because of collaboration gone too far. I try to warn students about what I expect ("your own words") , but I think I will be ramping up training on how to really avoid academic dishonesty issues this semester.

    "The game EteRNA, which was started by the Stanford biochemist Rhiju Das and the Carnegie Mellon computer scientist Adrien Treuille, allows researchers to farm out some of the intellectual legwork behind RNA design to 26,000 players, rather than a relatively few lab workers. Players are given a puzzle design-an RNA molecule in the shape of a star or a cross, for example-that they must fill in with the components, called nucleotides, to produce the most plausible solution. The community of players then votes for the blueprint it thinks will have the best chance of success in the lab. The Stanford researchers select the highest-rated blueprints and actually synthesize them. The scientists then report back the results of the experiments to the crowd to inform future designs. The crowd-sourcing has produced results that tend to be more effective than computer-generated arrangements. "Computational methods are not perfect in making these shapes," says Mr. Das, "and as we get to more and more complex ones, they essentially always fail, so we know that there are rules to be learned." Players are figuring out these principles on their own, says Mr. Treuille. He says that while they're more like a grandmother's instructions on baking a cake than a strict scientific formula, they work remarkably well in practice. "EteRNA players are extremely good at designing RNA's," says Mr. Treuille, "which is all the more surprising because the top algorithms published by scientists are not nearly so good. The gap is pretty dramatic.""

Campus Technology article about ePortfolios at PSU - 2 views

  • Evolving the E-Portfolio at Penn State By Bridget McCrea04/06/11 Pennsylvania State University's foray into e-portfolios started about 10 years ago, when static Web pages were used to store and display online versions of student resumes. Fairly innovative for their time, these early e-portfolios gave way to more dynamic versions of themselves a few years back as the university began rolling in Web 2.0 technologies. "When blogs, social networking and other interactive technologies came along, we tweaked our e-portfolio initiative," said Jeff Swain, innovation consultant for the university. "We wanted students to be able to develop interactive, online portfolios that would be able to stay and grow with them throughout their college careers, and beyond."

News: 'Now You See It' - Inside Higher Ed - 2 views

  • Q: What are some of the ways that you've applied ideas and research about attention and learning in your own classroom? A: I rarely lecture anymore. I structure my classes now with each unit led by two students, who are responsible for researching and assigning texts and writing assignments and who then are charged with grading those assignments. The next week, two other students become our peer leaders. Students learn the fine art of giving and receiving feedback and learning from one another. I structure midterms as collaborative “innovation challenges,” an incredibly difficult exercise which is also the best way of intellectually reviewing the course material I’ve ever come up with. In other words, more and more I insist on students’ taking responsibility for their learning and communicating their ideas to the general public using social media.
  • If you want to learn more, you can find syllabuses and blogs on both the HASTAC and the DMLCentral site. I posted about “This Is Your Brain on the Internet” and “Twenty-First Century Literacies.” I also led a forum on interactive pedagogy in large lecture classes.
