Quest to Learn School website - 0 views

  •  
    "Reason and Purpose Learning by Doing Designed to support the digital lives of young people and their capacity for learning, Quest to Learn is a school committed to graduating strong, engaged, literate citizens of a globally networked world. Through an innovative pedagogy that immerses students in differentiated, challenge-based contexts, the school acknowledges design, collaboration, and systems thinking as key literacies of the 21st century. Within an integrated, rigorous Regents-based curriculum students work with teachers to gain the skills necessary to meet these requirements, and even surpass them. On-going evaluation and feedback create opportunities for students to plan, revise, and reflect on their own learning. The overall curriculum is rooted in mathematical practices and the use of smart tools, with an explicit intent to innovate at the level of how students are assessed in context. Most importantly, teachers work with students to build individual and academic competencies and enrich youth identity development within contexts that are relevant and meaningful. The school has been designed to help students to bridge old and new literacies through learning about the world as a set of interconnected systems. Design and complex problem-solving are two big ideas of the school, as is a commitment to deep content learning with a strong focus on learning in rigorous, engaging, and relevant ways. It is a place where digital media meets books and students learn to think like designers, inventors, mathematicians, writers, and more. Q2L brings together teachers with a passion for content, a vision for helping kids to learn best, and a commitment to changing the way students will grow in the world. Quest to Learn has purposely responded not only to the growing evidence that digital media and games offer powerful models for reconsidering how and where young people learn, but also to the belief that access for all students to these opportunities is critical.

Turing's Cathedral. Author George Dyson in Conversation with John Hollar - YouTube - 0 views

  •  
    "Publiée le 19 mars 2012 par ComputerHistory [Recorded: March 7, 2012] I am thinking about something much more important than bombs. I am thinking about computers. John von Neumann, 1946 The most powerful technology of the last century was not the atomic bomb, but software-and both were invented by the same folks. Even as they were inventing it, the original geniuses imagined almost everything software has become since. At long last, George Dyson delivers the untold story of software's creation. It is an amazing tale brilliantly deciphered. Kevin Kelly, cofounder of WIRED magazine, author of What Technology Wants Legendary historian George Dyson vividly re-creates the scenes of focused experimentation, incredible mathematical insight, and pure creative genius that gave us computers, digital television, modern genetics, models of stellar evolution-in other words, computer code. In the 1940s and '50s, a group of eccentric geniuses-led by John von Neumann-gathered at the newly created Institute for Advanced Study in Princeton, New Jersey. Their joint project was the realization of the theoretical universal machine, an idea that had been put forth by mathematician Alan Turing. This group of brilliant engineers worked in isolation, almost entirely independent from industry and the traditional academic community. But because they relied exclusively on government funding, the government wanted its share of the results: the computer that they built also led directly to the hydrogen bomb. George Dyson has uncovered a wealth of new material about this project, and in bringing the story of these men and women and their ideas to life, he shows how the crucial advancements that dominated twentieth-century technology emerged from one computer in one laboratory, where the digital universe as we know it was born. Join John Hollar for a captivating conversation with Dyson about John von Neumann and the beginnings of the digital universe. This event is part of ou

  • The author would like us to believe that education is being “radically rethought” by the online and “blended” options that are available to students. But let’s be clear; the only things being rethought here are the delivery models of a traditional education and, most importantly, the financial models to sustain it and make lots of money for outside businesses who see technology and access as a way to not only line their pockets with taxpayer money but also bust the unions that stand in their way. 
  • To be honest, I think we’ve all got to stop cranking out blog posts and Tweets that tout new tools and the “10 Best Ways…” and instead begin to make the case in our blogs and in person that technology or not, this is about what is best for our kids. That in this moment, 20th Century rules will not work for 21st Century schools. That direct instruction and standardization will make us less competitive, not more. That those strategies will make our kids less able to create a living for themselves in the worlds they will live in. That as difficult as it may be for some to come to terms with, this moment requires a whole scale “radical rethink” in much different terms from the one J

Skeptic » About Us » A Brief Introduction - 1 views

  •  
    "A Brief Introduction All our science, measured against reality, is primitive and childlike - and yet it is the most precious thing we have. -Albert Einstein The Skeptics Society is a scientific and educational organization of scholars, scientists, historians, magicians, professors and teachers, and anyone curious about controversial ideas, extraordinary claims, revolutionary ideas, and the promotion of science. Our mission is to serve as an educational tool for those seeking clarification and viewpoints on those controversial ideas and claims. Under the direction of Dr. Michael Shermer, the Society engages in discussions with leading experts and investigates fringe science and paranormal claims. It is our hope that our efforts go a long way in promoting critical thinking and lifelong inquisitiveness in all individuals. I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them. -Baruch Spinoza Some people believe that skepticism is the rejection of new ideas, or worse, they confuse "skeptic" with "cynic" and think that skeptics are a bunch of grumpy curmudgeons unwilling to accept any claim that challenges the status quo. This is wrong. Skepticism is a provisional approach to claims. It is the application of reason to any and all ideas - no sacred cows allowed. In other words, skepticism is a method, not a position. Ideally, skeptics do not go into an investigation closed to the possibility that a phenomenon might be real or that a claim might be true. When we say we are "skeptical," we mean that we must see compelling evidence before we believe. Skepticism has a long historical tradition dating back to ancient Greece, when Socrates observed: "All I know is that I know nothing." But this pure position is sterile and unproductive and held by virtually no one. If you were skeptical about everything, you would have to be skeptical of your own skepticism. Like the dec

The Death and Life of Great American Cities - Wikipedia, the free encyclopedia - 0 views

  •  
    "The Death and Life of Great American Cities, by Jane Jacobs, is a greatly influential book on the subject of urban planning in the 20th century. First published in 1961, the book is a critique of modernist planning policies claimed by Jacobs to be destroying many existing inner-city communities. Reserving her most vitriolic criticism for the "rationalist" planners (specifically Robert Moses) of the 1950s and 1960s, Jacobs argued that modernist urban planning rejects the city, because it rejects human beings living in a community characterized by layered complexity and seeming chaos. The modernist planners used deductive reasoning to find principles by which to plan cities. Among these policies the most violent was urban renewal; the most prevalent was and is the separation of uses (i.e. residential, industrial, commercial). These policies, she claimed, destroy communities and innovative economies by creating isolated, unnatural urban spaces. In their place Jacobs advocated for "four generators of diversity", writing on page 151, "The necessity for these four conditions is the most important point this book has to make. In combination, these conditions create effective economic pools of use." Mixed uses. Short blocks. Buildings of various ages & states of repair. Density. Her aesthetic can be considered opposite to that of the modernists, upholding redundancy and vibrancy, against order and efficiency. She frequently cites New York City's Greenwich Village as an example of a vibrant urban community. The Village, like many similar communities, may well have been preserved, at least in part, by her writing and activism. The book also played a major role in the urban development of Toronto, Ontario, Canada, where Jacobs was involved in the campaign to stop the Spadina Expressway.[1] The book continues to be Jacobs' most influential, and is still widely read by both planning professionals and the general public.

Confessions of an Aca/Fan: Archives: A New Culture of Learning: An Interview with John ... - 1 views

  • Today, I want to call attention to a significant new book, A New Culture of Learning: Cultivating the Imagination for a World of Constant Change, written by two of my new colleagues at the University of Southern California -- Douglas Thomas and John Seely Brown.
  • John Seely Brown and Douglas Thomas lay out a step by step argument for why learning is changing in the 21st century and what schools need to do to accommodate these new practices.
  • My hope is that our schools will soon embrace the book's emphasis on knowing, making, and playing.
  • ...9 more annotations...
  • The fear is easy to understand. What we are essentially doing when we move to student-directed learning is undermining our own relatively stable (though I would argue obsolete) notions of expertise and replacing them something new and different.
  • One of the key arguments we are making is that the role of educators needs to shift away from being expert in a particular area of knowledge, to becoming expert in the ability to create and shape new learning environments.
  • how do we identify the narrowing range of content which probably does fall into this category and which provides a common baseline for other kinds of learning?
  • users are not so much creating content as they are constantly reshaping context.
  • The very idea of remix is about the productions of new meanings by reframing or shifting the context in which something means.
  • You challenge here what James Paul Gee has called the "content fetish," stressing that how we learn is more important than what we learn. How far are you willing to push this? Doesn't it matter whether children are learning the periodic table or the forms of alchemy practiced in the Harry Potter books? Or that they know Obama is Christian rather than Muslim?
  • throughout the book, we stress that knowledge, now more than ever, is becoming a where rather than a what or how.
  • The explicit is only one kind of content, which tells you what something means.
  • The tacit has its own layer of meaning. It tells why something is important to you, how it relates to your life and social practices.

Writing, Reading, and Social Media Literacy - Howard Rheingold - Now, New, Next - Harva... - 5 views

  • When I first faced students in a classroom, I was surprised to discover that the mythology I had believed about "digital natives" was not entirely accurate. Just because they're on Facebook and chat online during class and can send text messages with one hand does not mean that young people are acquainted with the rhetoric of blogging, understand the way wikis can be used collaboratively, or know the techniques necessary for vetting the validity of information discovered online. Just as learning the alphabet requires further education before a literate person can compose a coherent argument, learning the skills of effective social media use requires an education that today's institutions and teachers are ill-prepared to provide.
  • We don't have time for institutions to change, which is why I've worked to provide tools for those educators who are using social media to prepare students for the 21st century.

Users for Sale: Has Digital Illiteracy Turned Us Into Social Commodities? - 1 views

  • In answer to your question, engaging with people costs us privacy. It always has. I think the only way to behave is as if nothing is private. And then fight to make what you care about legal and acceptable.
    • David McGavock
       
      key point
  • You warn against the dangers of “selling our friends” by connecting our social graphs to various networks and apps. How does this damage our relationships, even if we’re doing it unwittingly?
  • Unwittingly, well, it’s more like when your friends keep inviting you to FarmVille or LinkedIn. When they unwittingly turn over their address book to one of these companies that’s really just in the business of swelling their subscriptions so that they can go have an IPO.
  • ...8 more annotations...
  • You advocate “programming literacy” in the online platforms we use every day. How much can the average web user be expected to understand?
  • I don’t think the average web users of this century will achieve basic programming literacy.
  • If they don’t know how to make the programs, then I’d at least want them to know what the programs they are using are for. It makes it so much more purposeful. You get much more predictable results using the right technologies for the right jobs.
  • I want people to be able to ask themselves, “What does this website want me to do? Who owns it? What is it for?”
  • You note how our traditional social contracts (e.g. I can steal anything I want, but I won’t do it out of shame, fear, etc.) break down due to the anonymity and distance of the web. How can we change this and still maintain an open online culture?
  • We have an economic operating system based in scarcity — that’s how we create markets — so we don’t have a great way yet of sharing abundant resources.
  • It’s a problem of imagination, not reality. We have imaginary boundaries.
  • rather than getting people to use the web responsibly and intelligently, it may be easier to build networks that treat the humans more responsibly and intelligently. Those of us who do build stuff, those of us who are responsible for how these technologies are deployed, we have the opportunity and obligation to build technologies that are intrinsically liberating — programs that reveal their intentions, and that submit to the intentions of their users.
    • David McGavock
       
      On one hand Rushkoff is saying all people need to become more literate of "programming". On the other hand he says that programmers need to focus on doing the job well (treat humans more responsibly - reveal their intentions more fully).

  • For those planning the future of Facebook, it’s hard to study what’s succeeded and failed for MySpace, in part because an exodus of users to Facebook is gradually turning MySpace into a ghost town.
  • If we learn from real-world cities instead of abandoned digital ones, what lessons might we take?
    • David McGavock
       
      Conclusions
  • The Jacobs/Moses debate suggests we need to be cautious of architectures that offer convenience and charge isolation as a price of admission. This is the concern Eli Pariser articulates in his (excellent) new book, “The Filter Bubble“.
  • He worries that between Google’s personalized search and the algorithmic decisions Facebook makes in displaying news from our friends, our online experience is an increasingly isolated one,
  • They’re cars, rather than public transit or busy sidewalks.
  • A map of Vancouver overlaid with my friends’ recommendations is one thing; one that recommends restaurants based on paid advertisements and doesn’t reveal this practice is another entirely.
  • The map I want is the one that lets me shuffle not just through my friends’ preferences but through annotations from different groups: first time visitors to the city; long-time Vancouverites; foodies; visitors from Japan, Korea or China.
    • David McGavock
       
      A diverse sampling of taste
  • People’s actions inscribe their intentions onto a city.
  • Online spaces are often so anxious to show me how my friends are using a space that they obscure how other audiences are using it.
  • It’s possible to find out what’s popular on Facebook to an audience broader than that of your friends.
    • David McGavock
       
      Something Google+ should consider
  • One of the reasons curation is such a helpful strategy for wandering is that it reveals community maxima. It can be helpful to know that Times Square is the most popular tourist destination in New York if only so we can avoid it.
  • knowing where Haitian taxi cab drivers go for goat soup is often useful data on where the best Haitian food is to be found.
  • If you want to explore beyond the places your friends think are the most enjoyable, or those the general public thinks are enjoyable, you need to seek out curators who are sufficiently far from you in cultural terms and who’ve annotated their cities in their own ways.
    • David McGavock
       
      key to breaking the filter bubbles
  • Geocaching is its own peculiar form of community annotation, where the immediate goal is leaving your signature on someone else’s logbook, but the deeper goal is encouraging you to explore in a way you otherwise wouldn’t.
  • SF0, founded by a trio of Chicagoans transplanted to San Francisco, was designed to encourage players to discover things they’d never seen or done in the city, in a way that encouraged independence and exploration.
  • Combining the insights we may find from studying the organization of cities with the ability to reshuffle and sort digitally may let us think about designing online spaces for serendipity in different and powerful ways.
    • David McGavock
       
      Conclusion?
  • - How do we design physical spaces to encourage serendipity? - What lessons about serendipity in physical spaces can we bring into the virtual realm? - How can we annotate the physical world, digitally, in ways that expand our encounters with the world, rather than limiting them?
    • David McGavock
       
      Questions over conclusion
  • We hope that cities are serendipity engines. By putting a diverse set of people and things together in a confined place, we increase the chances that we’re going to stumble onto the unexpected. It’s worth asking the question: do cities actually work this way?
  • Most of us are fairly predictable
  • We hope for random encounter with a diverse citizenry to build a web of weak ties that increases our sense of involvement in the community, as Bob Putnam suggested in Bowling Alone. And we worry that we may instead isolate and cocoon ourselves when faced with a situation where we feel like outsiders, as Putnam’s recent research suggests.
  • “Census data can describe the segregation of my block, but how about telling me how segregated my life is? Location data points in that direction.
  • Nathan Eagle, who has worked with Sandy Pentland at MIT’s Media Lab on the idea of “reality mining”, digesting huge sets of data like mobile phone records, estimates that he can predict the location of “low-entropy individuals” with 90-95% accuracy based on this type of data
  • We all filter the places we live into the places where we’re regulars and the ones we avoid, the parts of town where we feel familiar and where we feel foreign. We do this based on where we live, where we work, and who we like to spend time with.
  • I’m less concerned about left-right polarization in the US, and more concerned about us/them polarization around the world
  • through the design of the systems we use and our behavior with those systems, I see reasons to worry that our use of the internet may be less cosmopolitan and more isolated that we would hope.
  • There were – and are – reasons to distrust curators, but there’s a critical aspect of their work I believe we need to preserve as we move towards new models for organizing news.
    • David McGavock
       
      interesting view of curation
  • Countries that have more than 40 million or more internet users generally have a very strong bias towards local sources – the mean is roughly 95%/5%, which makes Americans look (slightly) cosmopolitan in comparison.
  • US broadcast media focuses much more on entertainment stories than on international news.)
  • What’s striking to me about this preference data is that there’s so little effort required to access international news sources like BBC, the Times of India or the Mail and Guardian – they’re one click away and don’t require crossing a language barrier – and how strong the “local” bias for national news sources appears to be.
  • on January 12th, I published “What if Tunisia had a revolution, but nobody watched?“… and I got a lot of phone calls when Ben Ali fled the country two days later.
  • The revolution in Tunisia caught intelligence and diplomatic services around the world flat-footed. It didn’t have to – there was a wealth of information being published on Tunisian Facebook pages
  • I’m forced to admit that there’s no way I would have known about the revolution brewing if I didn’t have close Tunisian friends.
  • I’m less interested in the ways in which we limit our paths through cities than in how we constrain what we do and don’t encounter online.
    • David McGavock
       
      key point
  • On the other hand, curators invariably have biases
  • We need mechanisms to ensure that search gets complemented with serendipity.
    • David McGavock
       
      Point we have been discussing. Filter bubbles
  • Facebook offers a different answer to the question, “What do I need to know?” – “You need to know what your friends and your friends of friends already know that you do not.”
    • David McGavock
       
      Facebook world = ummm....
  • there’s a decent chance that their collective intelligence has some blind spots
  • The problem, of course, is that if your friends don’t know about a revolution in Tunisia or a great new Vietnamese restaurant, you may not know either.
  • It’s worth asking whether that bubble is able to provide us with the serendipity we hope for from the web.
  • Serendipity, at first glance, looks like the positive side of unintended consequences, the happy accident. But that’s not what the term meant, at least originally.
  • The word was coined by Horace Walpole, an 18th century British aristocrat,
  • A Google search turns up 11 million pages with the term, including restaurants, movies and gift shops named “serendipity”, but very few on unexpected discovery through sagacity.
    • David McGavock
       
      Serendipity vs. Sagacity
  • he refers to a Persian fairy tale, The Three Princes of Serendip, in which the titular characters were “always making discoveries, by accidents and sagacity, of things they were not in quest of.”
  • Louis Pasteur observed, “In the fields of observation chance favors only the prepared mind.”
  • In “The Travels and Adventures of Serendipity”, he and Barber explore discovery in a General Electric laboratory under the leadership of Willis Whitney, who encouraged a work environment that focused as much on fun as it did on discovery.
    • David McGavock
       
      Sounds like Google. Tinkering, time to play, time to work.
  • If we want to create online spaces to encourage serendipity, we might start by learning from cities.
    • David McGavock
       
      Moving to the point of online learning
  • Our loss, I believe, is that we’ve lost sight of the idea that we could prepare ourselves for serendipity, both personally and structurally.
  • vibrancy comes from the ongoing chance encounter between people using a neighborhood for different purposes, encountering one another as their paths intersect and cross.
  • The neighborhoods Jacobs celebrates are certainly not the most efficient in terms of an individual’s ability to move quickly and independently. Vibrancy and efficiency may not be diametrically opposed, but it’s likely that the forces are in tension.

  • What is the effect of online availability ofjournal issues? It is possible that by makingmore research more available, online searchingcould conceivably broaden the work cited andlead researchers, as a collective, away from the“core”journals of their fields and to dispersedbut individually relevant work. I will show,however, that even as deeper journal back is-sues became available online, scientists andscholars cited more recent articles; even asmore total journals became available online,fewer were cited
    • srgupta
       
      Thesis
  • Figure 1 shows the speed of the shift toward commercial and free electronic provision of articles, and how deepening backfiles have made more early science readily available in recent years.
    • srgupta
       
      Clear evidence of increase in accessibility and availability of articles.
  • Panel regression models were used to explore the relation between online article availability and citation activity—average historical depth of citations, number of distinct articles and journals cited, and Herfindahl concentration of citations to particular articles and journals—over time (details on methods are in the Supporting Online Material)
    • srgupta
       
      Methodology
  • ...6 more annotations...
  • The graphs in Fig. 2 trace the influence of online access, estimated from the entire sample of articles, and illustrated for journals and subfields with the mean number of citations. Figure 2A shows the simultaneous effect of commercial and free online availability on the average age of citations
  • The first question was whether depth of citation—years between articles and the work they reference—is predicted by the depth of journal issues online—how many years back issues were electronically available during the previous year when scientists presumably drafted them into their papers.
  • Collectively, the models presented illustrate that as journal archives came online, either through commercial vendors or freely, citation patterns shifted. As deeper backfiles became available, more recent articles were referenced; as more articles became available, fewer were cited and citations became more concentrated within fewer articles. These changes likely mean that the shift from browsing in print to searching online facilitates avoidance of older and less relevant literature. Moreover, hyperlinking through an online archive puts experts in touch with consensus about what is the most important prior work—what work is broadly discussed and referenced. With both strategies, experts online bypass many of the marginally related articles that print researchers skim. If online researchers can more easily find prevailing opinion, they are more likely to follow it, leading to more citations referencing fewer articles. Research on the extreme inequality of Internet hyperlinks (14), scientific citations (15, 16), and other forms of “preferential attachment” (17, 18) suggests that near-random differences in quality amplify when agents become aware of each other’s choices. Agents view others’ choices as relevant information—a signal of quality—and factor them into their own reading and citation selections. By enabling scientists to quickly reach and converge with prevailing opinion, electronic journals hasten scientific consensus. But haste may cost more than the subscription to an online archive: Findings and ideas that do not become consensus quickly will be forgotten quickly .
    • srgupta
       
      Conclusion and possible explanation
  • This research ironically intimates that one of the chief values of print library research is poor indexing. Poor indexing—indexing by titles and authors, primarily within core journals— likely had unintended consequences that assisted the integration of science and scholarship. By drawing researchers through unrelated articles, print browsing and perusal may have facilitated broader comparisons and led researchers into the past. Modern graduate education parallels this shift in publication—shorter in years, more specialized in scope, culminating less frequently in a true dissertation than an album of articles (19)
