    Mutton said the number of computers spewing out spam had jumped from 400 to 2,000 machines on Wednesday - relatively small numbers, he said, but still apparently enough to overwhelm MasterCard and Visa. "I've been surprised at how effective its been," he said. "You don't need huge numbers of people to carry out an attack like that."

If San Francisco Crime were Elevation | Doug McCune - 0 views

  • Really nice. Be great to see the two combined – heatmaps and topography or atleast some kind of colour banding added to the topography. That would open up all kinds of possibilities – you could slice horizontally along the bands and create layers of different ranges. In fact mixing colour and topography would also give you a way of showing two sets of data concurrently – topography for prostitution and some kind of colour banding for wealth for example.
  • Makes the numbers come alive. G
  • Brilliant work! Can you cross this data with the physical typography? I’ve always been curious if safer neighborhoods are uphill.

  • It would be interesting to pull the data in from previous decades and see how the elevation has changed in different areas.
  • @adrian – it’s just raw totals, grouped geographically. These aren’t scientific by any means, I basically took the underlying pattern and extruded it out and smoothed it a bit to make it look “pretty”. But basically each image is the aggregate numbers for a single year of crime data.
  • @richard – yes, there is some smoothing in effect, which means that the ridge along Shotwell St (for the prostitution map) is indeed a bit smoothed between peaks. That’s not to say that there are only two peaks at Shotwell and 19th and Shotwell and 17th. There are incidents in between as well, but the big peaks at those major intersections does mean that the ridge between them appears higher than the actual incidents along those blocks support. A lot of people have commented on the usefulness of maps like these. I want to stress once again: this was done as an art project much more than a useful visualization. My goal was not to provide useful information that one could act on.
  • “one trick pony. these maps add nothing of value to a standard color plot.” I disagree: allowing for a third dimension of elevation makes the reality of concentration clearer – and half the point of crime mapping is to measure concentration, not simply “intensity.”
  • Great idea and nice work on the graphics, but there are at least three improvements you should make to reveal *true* patterns. Forgive me if you already did these. 1) Availability bias – normalize for population density (i.e. per capita activity) 2) Sampling bias – normalize for the number of cops on the beat (geographic and crime type) 2) Frame bias – break it up by daytime and night time

Tweeting the terror: How social media reacted to Mumbai - CNN.com - 0 views

  • One tweet from "Dupree" appeared to be coming from inside one of the hotels: "Mumbai terrorists are asking hotel reception for rooms of American citizens and holding them hostage on one floor." A group of Mumbai-based bloggers turned their Metroblog into a news wire service, while the blog MumbaiHelp offered to help users get through to their family and friends in the city, or to get information about them, and has had a number of successes. Flickr also proved a useful source of haunting images chronicling the aftermath of the attacks. Journalist Vinukumar Ranganathan's stream of photos were published by CNN and other major broadcasters. iReport.com: Are you there? Share your photos, videos and stories A Google Map showing the key locations and buildings with links to news stories and eyewitness accounts, and CNN's iReporters flooded the site with their videos and images of the terror attacks.
  • However, as is the case with such widespread dissemination of information, a vast number of the posts on Twitter amounted to unsubstantiated rumors and wild inaccuracies. For example, a rumor that the Indian government was asking tweeters to stop live updates to avoid compromising its security efforts was published and republished on the site.
  • As blogger Tim Mallon put it, "I started to see and (sic) ugly side to Twitter, far from being a crowd-sourced version of the news it was actually an incoherent, rumour-fueled mob operating in a mad echo chamber of tweets, re-tweets and re-re-tweets.

  • What is clear that although Twitter remains a useful tool for mobilizing efforts and gaining eyewitness accounts during a disaster, the sourcing of most of the news cannot be trusted. A quick trawl through the enormous numbers of tweets showed that most were sourced from mainstream media.

Cognitive Surplus: The Great Spare-Time Revolution | Magazine - 0 views

  • Somehow, watching television became a part-time job for every citizen in the developed world. But once we stop thinking of all that time as individual minutes to be whiled away and start thinking of it as a social asset that can be harnessed, it all looks very different. The buildup of this free time among the world’s educated population—maybe a trillion hours per year—is a new resource. It’s what I refer to as the cognitive surplus.
  • Shirky:
  • Pink: A surplus that post-TV media—blogs, wikis, and Twitter—can tap for other, often more valuable, uses.
  • ...8 more annotations...
  • he very nature of these new technologies fosters social connection—creating, contributing, sharing. When someone buys a TV, the number of consumers goes up by one, but the number of producers stays the same. When someone buys a computer or mobile phone, the number of consumers and producers both increase by one. This lets ordinary citizens, who’ve previously been locked out, pool their free time for activities they like and care about. So instead of that free time seeping away in front of the television set, the cognitive surplus is going to be poured into everything from goofy enterprises like lolcats, where people stick captions on cat photos, to serious political activities like Ushahidi.com, where people report human rights abuses.
  • All the time that people devote to Wikipedia—which that guy considered weird and wasteful—is really a tiny portion of our worldwide cognitive surplus. It’s less than one-tenth of 1 percent of the total.
  • Our third drive—our intrinsic motivation—can be even more powerful.
  • Shirky: Right—because television crowded out other forms of social engagement. Look, behavior is motivation filtered through opportunity. So if you see people behaving in new ways, like with Wikipedia and whatnot, it’s very unlikely that their motivations have changed, because human nature doesn’t change that quickly. It’s quite likely that the opportunities have changed.
  • When we lacked the ability to efficiently connect and collaborate with each other, that intrinsic motivation often didn’t surface. So we assumed that productive, public activities revolved around extrinsic motivation and external rewards. And we assumed that all rewards were substitutable for all other rewards. So I can pay you more or I can praise you or I can put a Lucite brick on your desk and it all works the same way.
  • When Deci took people who enjoyed solving complicated puzzles for fun and began paying them if they did the puzzles, they no longer wanted to play with those puzzles during their free time. And the science is overwhelming that for creative, conceptual tasks, those if-then rewards rarely work and often do harm.
  • Pink: Yes, often these outside motivators can give us less of what we want and more of what we don’t want. Think about that study of Israeli day care centers, which we both write about. When day care centers fined parents for being late to pick up their kids, the result was that more parents ended up coming late. People no longer felt a social obligation to behave well. Shirky: If you assume bad faith from the average participant, you’ll probably get it. In social media, the design principle that has worked remarkably well is to treat good faith as the normal case and to regard defections from that as essentially a special case to be solved.
  • Shirky: Well, organizations that are founded to solve problems end up committed to the preservation of the problems. So Trentway-Wagar, an Ontario-based bus company, sues PickupPal, an online ride-sharing service, because T-W isn’t committed to solving transportation problems. It’s committed to solving transportation problems with buses. In the media world, Britannica is now committed to making reference works that can’t easily be referred to, and the music industry is now distributing music that can’t easily be shared because new ways of distributing music undermine the old business model.

Cell Phones in the (Language) Classroom: Recasting the Debate (EDUCAUSE Quarterly) | ED... - 0 views

  • New Internet SMS and messaging services are proving especially useful to language teachers, turning the focus away from the particulars of language and writing and toward whole language oral output and pronunciation, even at the beginner level.
  • is the time to revisit and recast the debate over cell phones in education and to consider their relevance as engagement and assessment tools for foreign language teachers in particular.
  • And it is no longer only what takes place inside the classroom that needs debating. Paradigm shift also means embracing the notion that learning takes place in more collaborative, interactive ways and also — at least potentially — everywhere and (nearly) all the time.
  • ...11 more annotations...
  • The launch this year of Google Voice — representing as it does a free alternative or complement to costly language laboratory recording hardware and software — has profound and exciting implications for student engagement in general and the confluence of language instruction and cell phone technology in particular. The proliferation of cell phones among today’s students combined with the development of such new computer-mediated communication tools allows teachers to engage students in new ways in and out of the classroom.
  • My Google Voice number has served primarily as a messaging service students call (sometimes spontaneously during the instructional period, more often outside of the classroom) to record dialogues, poetry, even song, either individually or in pairs. These recordings are stored on Google servers, but can be downloaded and posted on course management pages (Moodle, Blackboard, Sakai, etc.) or podcasting, blogging, or social networking sites (I post particularly good recordings on my Spanish Facebook page).
  • maximizing student engagement during the class period is essential, as many students work and do not practice outside the classroom setting. Without getting into the debate over the front-end need for considerable comprehensible input, as a practical matter many students see paired work time (particularly in larger classes) as social time, which can lead to student-teacher conflict (no explanation needed).
  • for lower level classes I can instruct my students to form small groups and, within a given time frame, call my Google Voice number and record a narration of an illustration or picture sequence. In the higher level classes, I can ask groups to come up with a succinct recorded comparison/contrast analysis of two different perspectives (textual and/or auditory) on a given subject. Either way, embracing whole language oral output turns the focus from the particulars of language and writing to whole language and pronunciation. It also allows for efficient instructor identification of common problem points.
  • It is generally accepted that students work harder and become more engaged and invested in activities and assignments that might be publicly posted (on the Internet or otherwise). My own experience shows that students required to record speech of any kind in a computer laboratory setting spend considerable time preparing prior to recording. The very act of recording their voices — creating a permanent record of their speech — instilled a strong desire to perform well. In short, the act of recording increased students’ investment and engagement in the learning process.
  • on a post-recording survey of a Spanish 3 class of 21 students, I asked students to respond anonymously to the following survey question:“I practice my Spanish pronunciation before calling Google Voice… not at all once more than once repeatedly”A total of 89 percent of the 21 respondents answered either “b,” “c,” or “d,” with 26 percent responding “repeatedly.” Among the more entertaining and pertinent written comments offered on the anonymous survey were the following: “AHH!! I feel smart because I actually practice a lot before I call.” “It makes me nervous having to record, but I practice a lot to help me get over that.” “I do not do the Google Voice because I don’t want the whole class to hear me.”The final comment clearly referred to my tendency to play recordings for full class feedback — food for thought. Is that a motivating or inhibiting factor? It probably depends on the student.
  • A student who was frustrated at his performance in Spanish and was beginning to exhibit some anger management issues received the following Spanish translation of a Ralph Waldo Emerson quote via text message through Google Voice: Por cada minuto que estás enojado, pierdes sesenta segundos de felicidad. I did not supply a translation
  • The access that I had to that student combined with the ease and speed of communication presented by Google Voice solved more than a pronunciation problem; it likely helped me head off a building class management issue by engaging that student on his terms outside of the classroom setting.
  • “I have a student who hasn’t done any homework this quarter, and out of the blue he sent me a goofy text message to my Google Voice number — completely unrelated to Spanish — something like “I hate this rain”— and, being the nerdy teacher, I texted him immediately back in Spanish: “No me gusta la lluvia tampoco.” One day later, he walks in for the first time with his homework and makes a big production about turning it in. I can’t help but feel that the personal connection of texting helped him remember — and actually want to do — the work for my class.”
  • Surprisingly, these “irredeemably unreachable” students have proven highly receptive to the notion that their cell phones can and should be used for educational purposes. Figure 2, for example, shows a fairly typical SMS exchange on an oral homework assignment for intermediate level students. While not all students will text back when I supply SMS feedback, those that do, like this one, tend to be looking for specifics and positive reinforcement. How is this additional engagement and interaction bad?
  • Elite schools have spent vast sums of money on expensive language laboratory hardware and software as an approach to active engagement in the language learning process. They have provided their students with the latest and greatest in computer-assisted (language) learning and computer-mediated communication tools, at considerable cost.

  • hat, exactly, constitutes a valid, original work? What are the implications for how we assess and reward creativity? Can a college or university tap the same sources of innovative talent and energy as Google or Flickr? What are the risks of permitting or opening up to this activity?
    • Barbara Lindsey
       
      Good discussion point
  • Remix is the reworking or adaptation of an existing work. The remix may be subtle, or it may completely redefine how the work comes across. It may add elements from other works, but generally efforts are focused on creating an alternate version of the original. A mashup, on the other hand, involves the combination of two or more works that may be very different from one another. In this article, I will apply these terms both to content remixes and mashups, which originated as a music form but now could describe the mixing of any number of digital media sources, and to data mashups, which combine the data and functionalities of two or more Web applications.
  • Harper's article "The Ecstasy of Influence," the novelist Jonathan Lethem imaginatively reviews the history of appropriation and recasts it as essential to the act of creation.3
  • Lethem's article is a must-read for anyone with an interest in the history of ideas, creativity, and intellectual property. It brilliantly synthesizes multiple disciplines and perspectives into a wonderfully readable and compelling argument. It is also, as the subtitle of his article acknowledges, "a plagiarism." Virtually every passage is a direct lift from another source, as the author explains in his "Key," which gives the source for every line he "stole, warped, and cobbled together." (He also revised "nearly every sentence" at least slightly.) Lethem's ideas noted in the paragraph above were appropriated from Siva Vaidhyanathan, Craig Baldwin, Richard Posner, and George L. Dillon.
  • Reading Walter Benjamin's highly influential 1936 essay "The Work of Art in the Age of Mechanical Reproduction,"4 it's clear that the profound effects of reproductive technology were obvious at that time. As Gould argued in 1964 (influenced by theorists such as Marshall McLuhan5), changes in how art is produced, distributed, and consumed in the electronic age have deep effects on the character of the art itself.
  • Yet the technology developments of the past century have clearly corresponded with a new attitude toward the "aura" associated with a work of invention and with more aggressive attitudes toward appropriation. It's no mere coincidence that the rise of modernist genres using collage techniques and more fragmented structures accompanied the emergence of photography and audio recording.
  • Educational technologists may wonder if "remix" or "content mashup" are just hipper-sounding versions of the learning objects vision that has absorbed so much energy from so many talented people—with mostly disappointing results.
  • The question is, why should a culture of remix take hold when the learning object economy never did?
  • when most learning object repositories were floundering, resource-sharing services such as del.icio.us and Flickr were enjoying phenomenal growth, with their user communities eagerly contributing heaps of useful metadata via simple folksonomy-oriented tagging systems.
  • the standards/practices relationship implicit in the learning objects model has been reversed. With only the noblest of intentions, proponents of learning objects (and I was one of them) went at the problem of promoting reuse by establishing an arduous and complex set of interoperability standards and then working to persuade others to adopt those standards. Educators were asked to take on complex and ill-defined tasks in exchange for an uncertain payoff. Not surprisingly, almost all of them passed.
  • Discoverable Resources
  • Educators might justifiably argue that their materials are more authoritative, reliable, and instructionally sound than those found on the wider Web, but those materials are effectively rendered invisible and inaccessible if they are locked inside course management systems.
  • It's a dirty but open secret that many courses in private environments use copyrighted third-party materials in a way that pushes the limits of fair use—third-party IP is a big reason why many courses cannot easily be made open.
  • The potential payoff for using open and discoverable resources, open and transparent licensing, and open and remixable formats is huge: more reuse means that more dynamic content is being produced more economically, even if the reuse happens only within an organization. And when remixing happens in a social context on the open web, people learn from each other's process.
  • Part of making a resource reusable involves making the right choices for file formats.
  • To facilitate the remixing of materials, educators may want to consider making the source files that were used to create a piece of multimedia available along with the finished result.
  • In addition to choosing the right file format and perhaps offering the original sources, another issue to consider when publishing content online is the critical question: "Is there an RSS feed available?" If so, conversion tools such as Feed2JS (http://www.feed2JS.org) allow for the republication of RSS-ified content in any HTML Web environment, including a course management system, simply by copying and pasting a few lines of JavaScript code. When an original source syndicated with RSS is updated, that update is automatically rendered anywhere it has been republished.
  • Jack Schofield

  • "An API provides an interface and a set of rules that make it much easier to extract data from a website. It's a bit like a record company releasing the vocals, guitars and drums as separate tracks, so you would not have to use digital processing to extract the parts you wanted."1
  • What's new about mashed-up application development? In a sense, the factors that have promoted this approach are the same ones that have changed so much else about Web culture in recent years. Essential hardware and software has gotten more powerful and for the most part cheaper, while access to high-speed connectivity and the enhanced quality of online applications like Google Docs have improved to the point that Tim O'Reilly and others can talk of "the emergent Internet operating system."15 The growth of user-centered technologies such as blogs have fostered a DIY ("do it yourself") culture that increasingly sees online interaction as something that can be personalized and adapted on the individual level. As described earlier, light syndication and service models such as RSS have made it easier and faster than ever to create simple integrations of diverse media types. David Berlind, executive editor of ZDNet, explains: "With mashups, fewer technical skills are needed to become a developer than ever. Not only that, the simplest ones can be done in 10 or 15 minutes. Before, you had to be a pretty decent code jockey with languages like C++ or Visual Basic to turn your creativity into innovation. With mashups, much the same way blogging systems put Web publishing into the hands of millions of ordinary non-technical people, the barrier to developing applications and turning creativity into innovation is so low that there's a vacuum into which an entire new class of developers will be sucked."16
  • The ability to "clone" other users' mashups is especially exciting: a newcomer does not need to spend time learning how to structure the data flows but can simply copy an existing framework that looks useful and then make minor modifications to customize the result.19
    • Barbara Lindsey
       
      This is the idea behind the MIT repository--remixing content to suit local needs.
  • As with content remixing, open access to materials is not just a matter of some charitable impulse to share knowledge with the world; it is a core requirement for participating in some of the most exciting and innovative activity on the Web.
  • "My Maps" functionality
  • For those still wondering what the value proposition is for offering an open API, Google's development process offers a compelling example of the potential rewards.
    • Barbara Lindsey
       
      Wikinomics
  • Elsewhere, it is difficult to point to significant activity suggesting that the mashup ethos is taking hold in academia the way it is on the wider Web.
  • Yet for the most part, the notion of the data mashup and the required openness is not even a consideration in discussions of technology strategy in higher educational institutions. "Data integration" across campus systems is something that is handled by highly skilled professionals at highly skilled prices.
  • Revealing how a more adventurous and inclusive online development strategy might look on campus, Raymond Yee recently posted a comprehensive proposal for his university (UC Berkeley), in which he outlined a "technology platform" not unlike the one employed by Amazon.com (http://aws.amazon.com/)—resources and access that would be invaluable for the institution's programmers as well as for outside interests to build complementary services.
  • All too often, college and university administrators react to this type of innovation with suspicion and outright hostility rather than cooperation.
  • those of us in higher education who observe the successful practices in the wider Web world have an obligation to consider and discuss how we might apply these lessons in our own contexts. We might ask if the content we presently lock down could be made public with a license specifying reasonable terms for reuse. When choosing a content management system, we might consider how well it supports RSS syndication. In an excellent article in the March/April 2007 issue of EDUCAUSE Review, Joanne Berg, Lori Berquam, and Kathy Christoph listed a number of campus activities that could benefit from engaging social networking technologies.26
  • What might happen if we allow our campus innovators to integrate their practices in these areas in the same way that social networking application developers are already integrating theirs? What is the mission-critical data we cannot expose, and what can we expose with minimal risk? And if the notion of making data public seems too radical a step, can APIs be exposed to selected audiences, such as on-campus developers or consortia partners?

Half of U.S. Adults Use Social Media - 0 views

  • t's worth noting that in this particular study "social media" includes text messaging. Combined with blogging and social networking, these three technologies are used by 50% of U.S. adults for communication purposes.
  • 85% of rely on one of the three platforms to stay in touch with others.
  • Although these numbers look promising for our favorite genre, social media, they should probably be taken with a grain of salt. While we do believe that text messaging is an important method of communication, it doesn't quite fit with what the standard definition of social media is: blogging, social networking sites, and other web properties that engage collective groups of people to drive their content. We would like to see how the numbers really break down among the three "social media" activities they measured, but that data was not immediately available.
  • Side Note: Personally, I find the terminology "the great unwashed (masses)" a little demeaning. The fact is that those at the lower end of the technology-use spectrum don't use things like text messaging and the internet as much because they are usually economically disadvantaged - an unfortunate condition that has numerous causes including everything from poor educational resources to lack of job opportunities in their geographic region. Lumping this lower-income group into one "great unwashed" group was an unnecessarily cruel way to address those not participating in the social media revolution.

  • In exploratory qualitative research, we have undertaken indicates the consumer might take a broader view of what social media might mean. For example, it could be taken by consumers to mean any digital form of personal communication that helps enable peer collaboration and sharing. This softer, less-structured definition is possibly useful in determining possible future growth areas of personal social P2P media from a consumer-centric POV."

  • With such specific applications of technology and the limited use of other forms (for example, multimedia), students' low expectations for the use of technology in the curriculum is not surprising. Such constrained use of technology by the faculty in the curriculum and low student expectations may serve to limit innovation and creativity as well as the faculty's capacity to engage students more deeply in their subject matter. Like all organizations, colleges and universities respond to the demands placed upon them. Students' and institutions' low expectations for the use of technology for learning provide insufficient impetus for faculties to change their behavior and make broader, more innovative use of these tools in the service of learning.
  • Consider this scenario:
  • From the beginning, however, a problem arose in that those middle school students went on to high schools and later to colleges that did not (and do not) provide this type of rich learning experience—a learning experience that can best be achieved when technology is used in the service of learning.
  • Data obtained from these sessions with high school and college seniors in Indiana, Oregon, and Virginia
  • Less attention has been given to how to help students achieve the desired learning outcomes through technology.
  • comparatively little support has been devoted to helping faculty use computers and other technologies in creative and innovative ways to deepen student learning.
  • To develop intentional learners, the curriculum must go beyond helping students gain knowledge for knowledge's sake to engaging students in the construction of knowledge for the sake of addressing the challenges faced by a complex, global society.
  • institutional structures and practices to resolve technical problems that faculty invariably encounter are very limited or are not the type of aid needed. Such lack of support limits the amount of time faculty can spend on what they do best—building a compelling curriculum and integrating technology for more powerful learning.
  • integrating study abroad into courses back on the home campus;
  • Faculty concerns perhaps center less on being "replaceable" and more on worrying that the teaching and learning enterprise will be reduced to students gathering information that can be easily downloaded, causing them to rely too heavily on technology instead of intellect.
    • Barbara Lindsey
       
      Mentioned frequently by our group members.
  • First, traditional age students overwhelmingly prefer face-to-face contact with faculty to mediated communication. Second, technology used in the service of learning will require more—not less—sophistication on the part of students as they engage in processes of integration, translation, audience analysis, and critical judgment.
  • Faculty with expertise in one or more subjects, who have been exposed to what we know about how people learn, can determine how to enhance this learning through the use of technology. But simply understanding how to use technology will not provide the integration needed to reach the desired learning outcomes.
    • Barbara Lindsey
       
      Last sentence here most important.
  • There is a need for integrating technology that is in the service of learning throughout the curriculum. More intentional use of technology to capture what students know and are able to integrate in their learning is needed.

  • We've had social software for 40 years at most, dated from the Plato BBS system, and we've only had 10 years or so of widespread availability, so we're just finding out what works. We're still learning how to make these kinds of things.
  • So email doesn't necessarily support social patterns, group patterns, although it can. Ditto a weblog. If I'm Glenn Reynolds, and I'm publishing something with Comments Off and reaching a million users a month, that's really broadcast.
  • If it's a cluster of half a dozen LiveJournal users, on the other hand, talking about their lives with one another, that's social. So, again, weblogs are not necessarily social, although they can support social patterns.
  • So there's this very complicated moment of a group coming together, where enough individuals, for whatever reason, sort of agree that something worthwhile is happening, and the decision they make at that moment is: This is good and must be protected. And at that moment, even if it's subconscious, you start getting group effects. And the effects that we've seen come up over and over and over again in online communities.
  • You are at a party, and you get bored. You say "This isn't doing it for me anymore. I'd rather be someplace else.
  • The party fails to meet some threshold of interest. And then a really remarkable thing happens: You don't leave.
  • That kind of social stickiness is what Bion is talking about.
  • Twenty minutes later, one person stands up and gets their coat, and what happens? Suddenly everyone is getting their coats on, all at the same time. Which means that everyone had decided that the party was not for them, and no one had done anything about it, until finally this triggering event let the air out of the group, and everyone kind of felt okay about leaving.
  • This effect is so steady it's sometimes called the paradox of groups.
  • what's less obvious is that there are no members without a group.
  • there are some very specific patterns that they're entering into to defeat the ostensible purpose of the group meeting together. And he detailed three patterns.
  • The first is sex talk,
  • second basic pattern
  • The identification and vilification of external enemies.
  • So even if someone isn't really your enemy, identifying them as an enemy can cause a pleasant sense of group cohesion. And groups often gravitate towards members who are the most paranoid and make them leaders, because those are the people who are best at identifying external enemies.
  • third pattern Bion identified: Religious veneration
  • The religious pattern is, essentially, we have nominated something that's beyond critique.
  • So these are human patterns that have shown up on the Internet, not because of the software, but because it's being used by humans. Bion has identified this possibility of groups sandbagging their sophisticated goals with these basic urges. And what he finally came to, in analyzing this tension, is that group structure is necessary. Robert's Rules of Order are necessary. Constitutions are necessary. Norms, rituals, laws, the whole list of ways that we say, out of the universe of possible behaviors, we're going to draw a relatively small circle around the acceptable ones.
  • He said the group structure is necessary to defend the group from itself. Group structure exists to keep a group on target, on track, on message, on charter, whatever. To keep a group focused on its own sophisticated goals and to keep a group from sliding into these basic patterns. Group structure defends the group from the action of its own members.
  • technical and social issues are deeply intertwined. There's no way to completely separate them.
  • Some of the users wanted the system to continue to exist and to provide a forum for discussion. And other of the users, the high school boys, either didn't care or were actively inimical. And the system provided no way for the former group to defend itself from the latter.
  • What matters is, a group designed this and then was unable, in the context they'd set up, partly a technical and partly a social context, to save it from this attack from within. And attack from within is what matters.
  • This pattern has happened over and over and over again. Someone built the system, they assumed certain user behaviors. The users came on and exhibited different behaviors. And the people running the system discovered to their horror that the technological and social issues could not in fact be decoupled.
  • nd the worst crisis is the first crisis, because it's not just "We need to have some rules." It's also "We need to have some rules for making some rules." And this is what we see over and over again in large and long-lived social software systems. Constitutions are a necessary component of large, long-lived, heterogenous groups.
  • As a group commits to its existence as a group, and begins to think that the group is good or important, the chance that they will begin to call for additional structure, in order to defend themselves from themselves, gets very, very high.
  • The downside of going for size and scale above all else is that the dense, interconnected pattern that drives group conversation and collaboration isn't supportable at any large scale. Less is different -- small groups of people can engage in kinds of interaction that large groups can't. And so we blew past that interesting scale of small groups. Larger than a dozen, smaller than a few hundred, where people can actually have these conversational forms that can't be supported when you're talking about tens of thousands or millions of users, at least in a single group.
  • So the first answer to Why Now? is simply "Because it's time." I can't tell you why it took as long for weblogs to happen as it did, except to say it had absolutely nothing to do with technology. We had every bit of technology we needed to do weblogs the day Mosaic launched the first forms-capable browser. Every single piece of it was right there. Instead, we got Geocities. Why did we get Geocities and not weblogs? We didn't know what we were doing.
  • It took a long time to figure out that people talking to one another, instead of simply uploading badly-scanned photos of their cats, would be a useful pattern. We got the weblog pattern in around '96 with Drudge. We got weblog platforms starting in '98. The thing really was taking off in 2000. By last year, everyone realized: Omigod, this thing is going mainstream, and it's going to change everything.
  • Why was there an eight-year gap between a forms-capable browser and the Pepys diaries? I don't know. It just takes a while for people to get used to these ideas. So, first of all, this is a revolution in part because it is a revolution. We've internalized the ideas and people are now working with them. Second, the things that people are now building are web-native.
  • A weblog is web-native. It's the web all the way in. A wiki is a web-native way of hosting collaboration. It's lightweight, it's loosely coupled, it's easy to extend, it's easy to break down. And it's not just the surface, like oh, you can just do things in a form. It assumes http is transport. It assumes markup in the coding. RSS is a web-native way of doing syndication. So we're taking all of these tools and we're extending them in a way that lets us build new things really quickly.
  • Third, in David Weinberger's felicitous phrase, we can now start to have a Small Pieces Loosely Joined pattern.
  • You can say, in the conference call or the chat: "Go over to the wiki and look at this."
  • It's just three little pieces of software laid next to each other and held together with a little bit of social glue. This is an incredibly powerful pattern. It's different from: Let's take the Lotus juggernaut and add a web front-end.
  • And finally, and this is the thing that I think is the real freakout, is ubiquity.
  • In many situations, all people have access to the network. And "all" is a different kind of amount than "most." "All" lets you start taking things for granted.
  • But for some groups of people -- students, people in high-tech offices, knowledge workers -- everyone they work with is online. Everyone they're friends with is online. Everyone in their family is online.
  • And this pattern of ubiquity lets you start taking this for granted.
  • There's a second kind of ubiquity, which is the kind we're enjoying here thanks to Wifi. If you assume whenever a group of people are gathered together, that they can be both face to face and online at the same time, you can start to do different kinds of things. I now don't run a meeting without either having a chat room or a wiki up and running. Three weeks ago I ran a meeting for the Library of Congress. We had a wiki, set up by Socialtext, to capture a large and very dense amount of technical information on long-term digital preservation.
  • The people who organized the meeting had never used a wiki before, and now the Library of Congress is talking as if they always had a wiki for their meetings, and are assuming it's going to be at the next meeting as well -- the wiki went from novel to normal in a couple of days.
  • It really quickly becomes an assumption that a group can do things like "Oh, I took my PowerPoint slides, I showed them, and then I dumped them into the wiki. So now you can get at them." It becomes a sort of shared repository for group memory. This is new. These kinds of ubiquity, both everyone is online, and everyone who's in a room can be online together at the same time, can lead to new patterns.
  • "What is required to make a large, long-lived online group successful?" and I think I can now answer with some confidence: "It depends."
  • The normal experience of social software is failure. If you go into Yahoo groups and you map out the subscriptions, it is, unsurprisingly, a power law. There's a small number of highly populated groups, a moderate number of moderately populated groups, and this long, flat tail of failure. And the failure is inevitably more than 50% of the total mailing lists in any category. So it's not like a cake recipe. There's nothing you can do to make it come out right every time.
  • Of the things you have to accept, the first is that you cannot completely separate technical and social issues.
  • So the group is real. It will exhibit emergent effects. It can't be ignored, and it can't be programmed, which means you have an ongoing issue. And the best pattern, or at least the pattern that's worked the most often, is to put into the hands of the group itself the responsibility for defining what value is, and defending that value, rather than trying to ascribe those things in the software upfront.
  • Members are different than users. A pattern will arise in which there is some group of users that cares more than average about the integrity and success of the group as a whole. And that becomes your core group, Art Kleiner's phrase for "the group within the group that matters most."
  • But in all successful online communities that I've looked at, a core group arises that cares about and gardens effectively. Gardens the environment, to keep it growing, to keep it healthy.
  • The core group has rights that trump individual rights in some situations
  • And absolute citizenship, with the idea that if you can log in, you are a citizen, is a harmful pattern, because it is the tyranny of the majority. So the core group needs ways to defend itself -- both in getting started and because of the effects I talked about earlier -- the core group needs to defend itself so that it can stay on its sophisticated goals and away from its basic instincts.
  • All groups of any integrity have a constitution. The constitution is always partly formal and partly informal. A
  • If you were going to build a piece of social software to support large and long-lived groups, what would you design for? The first thing you would design for is handles the user can invest in.
  • Second, you have to design a way for there to be members in good standing. Have to design some way in which good works get recognized. The minimal way is, posts appear with identity.
  • Three, you need barriers to participation.
  • It has to be hard to do at least some things on the system for some users, or the core group will not have the tools that they need to defend themselves.
  • The user of social software is the group, not the individual.
  • Reputation is not necessarily portable from one situation to another
  • If you want a good reputation system, just let me remember who you are. And if you do me a favor, I'll remember it. And I won't store it in the front of my brain, I'll store it here, in the back. I'll just get a good feeling next time I get email from you; I won't even remember why. And if you do me a disservice and I get email from you, my temples will start to throb, and I won't even remember why. If you give users a way of remembering one another, reputation will happen,

The Associated Press: Aid groups enlist Google to help in Haiti effort - 0 views

  • Over a normal Google Earth screen of Haiti, blue spots appear showing where Haitians have settled. Some are named by street, zone or landmark, and others are simply numbered as "IDP" — internally displaced persons — camps.Each blue spot can be clicked on, calling up an information box that gives a site's longitude and latitude, commune and estimated number of families and individuals. The details are updated regularly so that, in theory, charities and government officials can foresee aid shortfalls, and potential dangers such as landslides and floods.
  • "It gives you a quick snapshot: 'Hey, look, there's no water there,'" Kelly said. "When something happens, the initial questions we ask are: 'Where is everyone? How are they living? What services are they getting?'"
  • "A lot of time and effort goes into logistics. If you don't know what's coming, where to take it, you are in trouble," Kelly said. "We need to understand, not in month three but in week two, where people have moved and what their conditions are. This is going to cut through a lot of bureaucracy."
  •  
    Aid workers, with the help of Google Earth, are uploading key information onto the Web to illustrate the needs of hundreds of thousands of people left homeless by Haiti's earthquake - an innovation that could significantly boost the ability to respond to future disasters.

Deliberate Engagement of Laptops in Large Lecture Classes to Improve Attentiveness and ... - 0 views

  •  
    The value of in-class Internet technologies to student attentiveness, engagement, and learning remains both controversial and filled with promising potential. In this study, students were given the option to use LectureTools, an interactive suite of tools designed specifically for larger classes. The availability of these tools dramatically changed the mechanics of the course as over 90% of students attending lecture voluntarily brought their laptops to class. On one hand, surveys over multiple semesters show that students believe the availability of a laptop is more likely to increase their time on tasks unrelated to the conduct of the course. On the other hand, the surveys also ascertained that students felt more attentive with the technology, significantly more engaged, and able to learn more with the technology than in similar classes without it. LectureTools also led to a dramatic increase in the number of students posing questions during class time, with more than half posing at least one question during class over the course of a semester, a percentage far higher than achieved in semesters prior to the use of this technology. These results suggest that while having laptops in the classroom can be a distraction to students, students of today show confidence that they are capable of productive multitasking, showing that they not only can handle this technology when applied through "deliberate engagement" using tools like LectureTools, but thrive with it, as seen through improved attentiveness, learning, and overall engagement even in larger classes.

Learning Reimagined: Participatory, Peer, Global, Online | DMLcentral - 1 views

  • I have found that in both my traditional physical classrooms and online environments, the chances of successful outcomes are multiplied when every person in the group makes a commitment to active participation in helping others learn.
  • When a sufficient number of people jump in and start contributing and building on one another's contributions, it becomes clear to all that it's not just about the teacher's performance and the student's ability to complete assignments. It's about our joint effort to make the whole of our encounter more valuable than just the sum of our individual learning.
  • I type roles on the whiteboard and show how to use the whiteboard tools to enter, format and move around elements. Roles include searchers, chat summarizers, session summarizers, mindmap leaders, session bloggers. I ask co-learners to write their own names on the whiteboard next to the roles they want to take, show them how to create break-out rooms to coordinate their collaborations, and ask the summarizers to feed their output to the bloggers, who take responsibility for posting a reflective summary of the session later

      How about we try this out in our online sessions?

  • It's confusing at first, but it is also flowing.
  • Yes, we're a collective intelligence, which is exhilarating, but we're a toddler collective intelligence, stumbling around learning to walk and trying to figure out where we're going at the same time. A number of new skills are required in short order. Information and communication flow through multiple simultaneous channels. The enterprise is challenging - that's part of the exercise. Taking my direction from George Siemens' ideas about networked learning ("we emphasize that early course experiences tend to be overwhelming and chaotic") I assure co-learners early and often that we can relax, accept and even embrace the chaos, and regard our networked attempts to make sense of it as the scaffold for our co-learning. 
  • Instead of seeking to put every fact in its place in an existing well-ordered taxonomy, why not seek to learn together by asking questions about what puzzles us, then organizing our discussions and mining them for knowledge?
  • Sometimes, I get into predicaments and don't know how to quit a webtour or place people in breakout rooms. So I calmly start exploring possible solutions, talking about it as I try to recover. While doing so, I also talk about the importance of exploring close enough to the edge to fall over it frequently. I model tolerance for error, learning from error, pushing the envelope of tech. Indeed, I've found that the earlier I can break something and fix it in public, the better. We talk about what works and what doesn't, discard what doesn't suit our purposes, push a tool further if it helps us learn together. It requires regular doses of humility to abandon what seemed like a bright idea at the time.
  • The objective is a culture of conversation that troubleshoots practical skills, explores theoretical underpinnings, dissects social implications.
  • Our internal social bookmarks enable us to create a mini-collective-intelligence by gathering resources about our discussion topics, selecting or writing descriptive snippets, assigning tags. The emerging tag-cloud serves as an index to the resources.
  • Wiki-work is about collaborative authoring.
  • In the process of using these tools to try to make sense together, we co-construct our learning. The last week of the course is about re-examining our learning process, reiterating the most important things we've learned, and redesigning the parts of the process that didn't work so well.
