My School, Meet MySpace: Social Networking at School | Edutopia - 0 views

  • Months before the newly hired teachers at Philadelphia's Science Leadership Academy (SLA) started their jobs, they began the consuming work of creating the high school of their dreams -- without meeting face to face. They articulated a vision, planned curriculum, designed assessment rubrics, debated discipline policies, and even hammered out daily schedules using the sort of networking tools -- messaging, file swapping, idea sharing, and blogging -- kids love on sites such as MySpace.
  • hen, weeks before the first day of school, the incoming students jumped onboard -- or, more precisely, onto the Science Leadership Academy Web site -- to meet, talk with their teachers, and share their hopes for their education. So began a conversation that still perks along 24/7 in SLA classrooms and cyberspace. It's a bold experiment to redefine learning spaces, the roles and relationships of teachers and students, and the mission of the modern high school.
  • When I hear people say it's our job to create the twenty-first-century workforce, it scares the hell out of me," says Chris Lehmann, SLA's founding principal. "Our job is to create twenty-first-century citizens. We need workers, yes, but we also need scholars, activists, parents -- compassionate, engaged people. We're not reinventing schools to create a new version of a trade school. We're reinventing schools to help kids be adaptable in a world that is changing at a blinding rate."

  • It's the spirit of science rather than hardcore curriculum that permeates SLA. "In science education, inquiry-based learning is the foothold," Lehmann says. "We asked, 'What does it mean to build a school where everything is based on the core values of science: inquiry, research, collaboration, presentation, and reflection?'"
  • It means the first-year curriculum is built around essential questions: Who am I? What influences my identity? How do I interact with my world? In addition to science, math, and engineering, core courses include African American history, Spanish, English, and a basic how-to class in technology that also covers Internet safety and the ethical use of information and software. Classes focus less on facts to be memorized and more on skills and knowledge for students to master independently and incorporate into their lives. Students rarely take tests; they write reflections and do "culminating" projects. Learning doesn't merely cross disciplines -- it shatters outdated departmental divisions. Recently, for instance, kids studied atomic weights in biochemistry (itself a homegrown interdisciplinary course), did mole calculations in algebra, and created Dalton models (diagrams that illustrate molecular structures) in art.
  • This is Dewey for the digital age, old-fashioned progressive education with a technological twist.
  • computers and networking are central to learning at, and shaping the culture of, SLA. "
  • he zest to experiment -- and the determination to use technology to run a school not better, but altogether differently -- began with Lehmann and the teachers last spring when they planned SLA online. Their use of Moodle, an open source course-management system, proved so easy and inspired such productive collaboration that Lehmann adopted it as the school's platform. It's rare to see a dog-eared textbook or pad of paper at SLA; everybody works on iBooks. Students do research on the Internet, post assignments on class Moodle sites, and share information through forums, chat, bookmarks, and new software they seem to discover every day.
  • Teachers continue to use Moodle to plan, dream, and learn, to log attendance and student performance, and to talk about everything -- from the student who shows up each morning without a winter coat to cool new software for tagging research sources. There's also a schoolwide forum called SLA Talk, a combination bulletin board, assembly, PA system, and rap session.
  • Web technology, of course, can do more than get people talking with those they see every day; people can communicate with anyone anywhere. Students at SLA are learning how to use social-networking tools to forge intellectual connections.
  • In October, Lehmann noticed that students were sorting themselves by race in the lunchroom and some clubs. He felt disturbed and started a passionate thread on self-segregation.
  • "Having the conversation changed the way kids looked at themselves," he says.
  • "What I like best about this school is the sense of community," says student Hannah Feldman. "You're not just here to learn, even though you do learn a lot. It's more like a second home."
  • As part of the study of memoirs, for example, Alexa Dunn's English class read Funny in Farsi, Firoozeh Dumas's account of growing up Iranian in the United States -- yes, the students do read books -- and talked with the author in California via Skype. The students also wrote their own memoirs and uploaded them to SLA's network for the teacher and class to read and edit. Then, digital arts teacher Marcie Hull showed the students GarageBand, which they used to turn their memoirs into podcasts. These they posted on the education social-networking site EduSpaces (formerly Elgg); they also posted blogs about the memoirs.

Web 2.0: A New Wave of Innovation for Teaching and Learning? (EDUCAUSE Review) | EDUCAU... - 0 views

  • Web 2.0. It is about no single new development. Moreover, the term is often applied to a heterogeneous mix of relatively familiar and also very emergent technologies
  • Ultimately, the label “Web 2.0” is far less important than the concepts, projects, and practices included in its scope.
  • Social software has emerged as a major component of the Web 2.0 movement. The idea dates as far back as the 1960s and JCR Licklider’s thoughts on using networked computing to connect people in order to boost their knowledge and their ability to learn. The Internet technologies of the subsequent generation have been profoundly social, as listservs, Usenet groups, discussion software, groupware, and Web-based communities have linked people around the world.
  • ...26 more annotations...
  • It is true that blogs are Web pages, but their reverse-chronological structure implies a different rhetorical purpose than a Web page, which has no inherent timeliness. That altered rhetoric helped shape a different audience, the blogging public, with its emergent social practices of blogrolling, extensive hyperlinking, and discussion threads attached not to pages but to content chunks within them. Reading and searching this world is significantly different from searching the entire Web world. Still, social software does not indicate a sharp break with the old but, rather, the gradual emergence of a new type of practice.
  • Rather than following the notion of the Web as book, they are predicated on microcontent. Blogs are about posts, not pages. Wikis are streams of conversation, revision, amendment, and truncation. Podcasts are shuttled between Web sites, RSS feeds, and diverse players. These content blocks can be saved, summarized, addressed, copied, quoted, and built into new projects. Browsers respond to this boom in microcontent with bookmarklets in toolbars, letting users fling something from one page into a Web service that yields up another page. AJAX-style pages feed content bits into pages without reloading them, like the frames of old but without such blatant seams. They combine the widely used, open XML standard with Java functions.3 Google Maps is a popular example of this, smoothly drawing directional information and satellite imagery down into a browser.
  • Web 2.0 builds on this original microcontent drive, with users developing Web content, often collaboratively and often open to the world.
  • openness remains a hallmark of this emergent movement, both ideologically and technologically.
  • Drawing on the “wisdom of crowds” argument, Web 2.0 services respond more deeply to users than Web 1.0 services. A leading form of this is a controversial new form of metadata, the folksonomy.
  • Third, people tend to tag socially. That is, they learn from other taggers and respond to other, published groups of tags, or “tagsets.”
  • First, users actually use tags.
  • Social bookmarking is one of the signature Web 2.0 categories, one that did not exist a few years ago and that is now represented by dozens of projects.
  • This is classic social software—and a rare case of people connecting through shared metadata.
  • RawSugar (http://www.rawsugar.com/) and several others expand user personalization. They can present a user’s picture, some background about the person, a feed of their interests, and so on, creating a broader base for bookmark publishing and sharing. This may extend the appeal of the practice to those who find the focus of del.icio.us too narrow. In this way too, a Web 2.0 project learns from others—here, blogs and social networking tools.
  • How can social bookmarking play a role in higher education? Pedagogical applications stem from their affordance of collaborative information discovery.
  • First, they act as an “outboard memory,” a location to store links that might be lost to time, scattered across different browser bookmark settings, or distributed in e-mails, printouts, and Web links. Second, finding people with related interests can magnify one’s work by learning from others or by leading to new collaborations. Third, the practice of user-created tagging can offer new perspectives on one’s research, as clusters of tags reveal patterns (or absences) not immediately visible by examining one of several URLs. Fourth, the ability to create multi-authored bookmark pages can be useful for team projects, as each member can upload resources discovered, no matter their location or timing. Tagging can then surface individual perspectives within the collective. Fifth, following a bookmark site gives insights into the owner’s (or owners’) research, which could play well in a classroom setting as an instructor tracks students’ progress. Students, in turn, can learn from their professor’s discoveries.
  • After e-mail lists, discussion forums, groupware, documents edited and exchanged between individuals, and blogs, perhaps the writing application most thoroughly grounded in social interaction is the wiki. Wiki pages allow users to quickly edit their content from within the browser window.11 They originally hit the Web in the late 1990s (another sign that Web 2.0 is emergent and historical, not a brand-new thing)
  • How do social writing platforms intersect with the world of higher education? They appear to be logistically useful tools for a variety of campus needs, from student group learning to faculty department work to staff collaborations. Pedagogically, one can imagine writing exercises based on these tools, building on the established body of collaborative composition practice. These services offer an alternative platform for peer editing, supporting the now-traditional elements of computer-mediated writing—asynchronous writing, groupwork for distributed members
  • Blogging has become, in many ways, the signature item of social software, being a form of digital writing that has grown rapidly into an influential force in many venues, both on- and off-line. One reason for the popularity of blogs is the way they embody the read/write Web notion. Readers can push back on a blog post by commenting on it. These comments are then addressable, forming new microcontent. Web services have grown up around blog comments, most recently in the form of aggregation tools, such as coComment (http://www.cocomment.com/). CoComment lets users keep track of their comments across myriad sites, via a tiny bookmarklet and a single Web page.
  • Technorati (http://technorati.com/) and IceRocket (http://icerocket.com/) head in the opposite direction of these sites, searching for who (usually a blogger) has recently linked to a specific item or site. Technorati is perhaps the most famous blog-search tool. Among other functions, it has emphasized tagging as part of search and discovery, recommending (and rewarding) users who add tags to their blog posts. Bloggers can register their site for free with Technorati; their posts will then be searchable by content and supplemental tags.
  • Many of these services allow users to save their searches as RSS feeds to be returned to and examined in an RSS reader, such as Bloglines (http://www.bloglines.com/) or NetNewsWire (http://ranchero.com/netnewswire/). This subtle ability is neatly recursive in Web 2.0 terms, since it lets users create microcontent (RSS search terms) about microcontent (blog posts). Being merely text strings, such search feeds are shareable in all sorts of ways, so one can imagine collaborative research projects based on growing swarms of these feeds—social bookmarking plus social search.
  • Students can search the blogosphere for political commentary, current cultural items, public developments in science, business news, and so on.
  • The ability to save and share a search, and in the case of PubSub, to literally search the future, lets students and faculty follow a search over time, perhaps across a span of weeks in a semester. As the live content changes, tools like Waypath’s topic stream, BlogPulse’s trend visualizations, or DayPop’s word generator let a student analyze how a story, topic, idea, or discussion changes over time. Furthermore, the social nature of these tools means that collaboration between classes, departments, campuses, or regions is easily supported. One could imagine faculty and students across the United States following, for example, the career of an Islamic feminist or the outcome of a genomic patent and discussing the issue through these and other Web 2.0 tools. Such a collaboration could, in turn, be discovered, followed, and perhaps joined by students and faculty around the world. Extending the image, one can imagine such a social research object becoming a learning object or an alternative to courseware.
  • A glance at Blogdex offers a rough snapshot of what the blogosphere is tending to pay attention to.
  • A closer look at an individual Blogdex result reveals the blogs that link to a story. As we saw with del.icio.us, this publication of interest allows the user to follow up on commentary, to see why those links are there, and to learn about those doing the linking. Once again, this is a service that connects people through shared interest in information.
  • The rich search possibilities opened up by these tools can further enhance the pedagogy of current events. A political science class could explore different views of a news story through traditional media using Google News, then from the world of blogs via Memeorandum. A history class could use Blogdex in an exercise in thinking about worldviews. There are also possibilities for a campus information environment. What would a student newspaper look like, for example, with a section based on the Digg approach or the OhmyNews structure? Thematizing these tools as objects for academic scrutiny, the operation and success of such projects is worthy of study in numerous disciplines, from communication to media studies, sociology to computer science.
  • At the same time, many services are hosted externally to academia. They are the creations of enthusiasts or business enterprises and do not necessarily embrace the culture of higher education.
  • Lawrence Lessig, J. D. Lasica, and others remind us that as tools get easier to use and practices become more widespread, it also becomes easier for average citizens to commit copyright violations.19
    • Barbara Lindsey
       
      Which is why he led the Creative Commons Movement and why he exhorts us to re-imagine copyright.
  • Web 2.0’s lowered barrier to entry may influence a variety of cultural forms with powerful implications for education, from storytelling to classroom teaching to individual learning. It is much simpler to set up a del.icio.us tag for a topic one wants to pursue or to spin off a blog or blog departmental topic than it is to physically meet co-learners and experts in a classroom or even to track down a professor. Starting a wiki-level text entry is far easier than beginning an article or book.
  • How can higher education respond, when it offers a complex, contradictory mix of openness and restriction, public engagement and cloistering?

Shirky: A Group Is Its Own Worst Enemy - 1 views

  • April 24, 2003
  • I want to talk about a pattern I've seen over and over again in social software that supports large and long-lived groups.
  • definition of social software
  • ...59 more annotations...
  • It's software that supports group interaction
  • how radical that pattern is. The Internet supports lots of communications patterns, principally point-to-point and two-way, one-to-many outbound, and many-to-many two-way.
  • Prior to the Internet, the last technology that had any real effect on the way people sat down and talked together was the table.
  • 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.
  • 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 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.
  • 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,

Taking Diigo Beyond the Bookmark - 0 views

  • Any writer knows the value of good research and with Diigo the process just got easier. Here’s a couple of ideas: tag items based on chapter, subject tag items for a bibliography jot a few notes to give context or your thoughts at the time highlight the section you intend to use and save the time of reviewing the entire page Diigo becomes even more essential in a collaboration project. The Forrester team used Delicious during their research for the book  Groundswell and I bet they could have used Diigo features like highlighting, comments, groups, and conversations.
  • tag recipes as appetizers, entrees, or desserts tag as vegetarian, diet, gluten free, or my favorite “enough-calories-to-make-Paula-Deen-blush” disclosure: the above link leads to my wife food blog MakeLifeDelicious.com, it’s the greatest food blog on earth #unbiased tag by ingredients highlight cooking times and pics
  • I love Diigo too. My son (10 years old) is working on his IB Exhibition on Water Pollution. He is working as part of a team. I helped them create a group for their topic so that they and their teacher can add resources, highlight text and tag interesting facts about the subject from home. Also, I am in a master's in education media design and am using Diigo to organize my resources for my Action Research project. Diigo is a great tool. Thanks for posting.

  • A real revelation for us, however, has been to use Diigo for internal staff communication. I've set up a News group for people to share any useful careers-related articles they come across. We also have various Jobs/Scholarships groups to share relevant graduate vacancies we find. The RSS feeds from these then post to Twitter and our own Jobs and Further Study pages. Saves a lot of time entering the details into our own database and gets the information to our students and graduates quicker. Hopefully! It also keeps staff abreast with up-to-date jobs information. Diigo is great!

YouTube Launches Auto-Captioning for Videos - 0 views

  • ouTube, Google, Stanford, Berkeley, and the California School for the Deaf (CSD) are about to speak on YouTube and accessibility.
  • Now the Google Speech Technology team is speaking about the challenges they faced to get auto-captioning operational. Their vision was to create accurate captions for all videos in all languages, but had to deal with huge vocabularies, background noise, poor recordings, accent variability, and distinguishing between song and speech.- Google’s approach is to deliver captions from the cloud, given them the ability to rapidly iterate and model at a large scale.
  • You can only caption your own videos — you can’t just caption someone else’s videos.
  • ...4 more annotations...
  • You can see the full caption file with timestamps and even download them as a text document. You can also upload your own captions as its own track — useful if auto-captioning isn’t doing the job or to make edits to the auto-captioned text.
  • With auto-captioning, these people can simply use text-based search to find what they need.
    • Chenwen Hong
       
      This means auto-captioning works well as an index for videos. One of its strengths, particularly for us instructors, can be that it helps us effeciently locate relevant clips of videos. This function should also be helpful to our students because we can add notes into the clips at specific frames. Well, the downside is that one might misinterpret videos or misunderstand creators' intentions when using only parts of the videos to suit one's own purposes.
  • You can specify search only brings up videos with closed captioning (it shows the cc icon in search). In the past, when he was at MIT, he couldn’t understand lectures because he had no sign interpreter. Now he can use the captioning to watch lectures he missed.
  • Now students of the California School for the Deaf are speaking (sign language) on how they feel not excluded anymore from the major phenomenon of web video and are grateful to Google for building this technology.

  • The three biggest success stories of independent social media projects taking off in Africa are Afrigator (a South African aggregator of African blogs and news), Zoopy (a YouTube/Flickr like service also out of South Africa) and Ushahidi (an SMS crisis reporting and mapping engine from Kenya). All three have drawn international attention which resulted in a major investment for Zoopy and Afrigator's acquisition (ReadWriteWeb's coverage). Meanwhile Ushahidi has successfully raised several rounds of funding after winning the Net2 Mashup Compeition prize of $25,000.
  • Afrigator defines itself as "a social media aggregator and directory built especially for African digital citizens who publish and consume content on the web."
  • Zoopy is a South African social media tool created by Jason Elk that allows users to upload videos, podcasts, and pictures and share them on the web.
  • Ushahidi relies heavily upon GoogleMaps, which it uses for mapping reports of incidents. It's built on the Zend framework for PHP and uses a number of different protocols for SMS, GPRS and mapping data.

  • The applications to follow are definitely the ones that leverage the mobile telephony infrastructure. An overwhelming portion of African users have no convenient access beyond cellular terminals - and that has spawned very innovative solutions based on existing and widely accessible technologies such as SMS. Examples abound such as Mpesa, Celpay, Etranzact and everyone else who is thriving in that formerly almost entirely cash-bound insecure environment. Underdeveloped banking and underdeveloped fixed telecommunications infrastructures are huge opportunities.

      Internet is expensive in Africa, at least where I was in Benin. It was a dollar an hour where I was. And teachers only earned $3 a day.

      I was in Benin for nine months in 2006-2007 and can attest to how expensive it is to talk on cell phones- for local calls! A 15 min. local call cost about $20. I remember thinking how calling from the U.S. to Benin was cheaper than making local calls in Benin.

      The research shows that no one can multitask effectively... See John Medina and Brain Rules, for example.
  • Workers anticipated having a single profession for the duration of their working lives. Education was based on a factory-like, "one size fits all" model. Talent was developed by weeding out those who could not do well in a monochromatic learning environment.

  • learners construct knowledge by understanding new information building on their current understanding and expertise. Constructivism contradicts the idea that learning is the transmission of content to a passive receiver. Instead, it views learning as an active process, always based on the learner's current understanding or intellectual paradigm. Knowledge is constructed by assimilating new information into the learner's knowledge paradigm. A learner does not come to a classroom or a course Web site with a mind that is a tabula rasa, a blank slate. Each learner arrives at a learning "site" with some preexisting level of understanding.
  • Learning science research also highlights the importance of learner engagement, or as the American Psychological Association describes it, intentional learning.1 This means that learners must have a "metaperspective" from which to view and assess their own learning, which is often referred to as metacognition.2 An active learning environment provides the opportunity to assess one's own learning, enabling learners to make decisions about the course, as well as reflect on and assess their progress. In the past, the measure of learning was the final grade (a summative measure). But a final grade is merely a measure of the student's performance on tests. It does not measure the learning that did—or did not—take place. To encourage learning, summative testing or assessments must be combined with formative assessments. Formative assessment is not directly associated with the final grade; it helps learners understand their learning and make decisions about next steps based on that understanding.
  • research indicating that learning is encouraged when it includes social components such as debate or direct engagement with peers and experts. Learning is strengthened through social interactions, interpersonal relations, and communication with others.
  • Research indicates that learners need to be active with respect to their own learning process and assessment. Net Gen students' goal and achievement orientation comes into play here: that achievement focus can be directed toward quizzes and exercises that assist learners in evaluating their progress toward learning goals.
  • Obviously not all forms of learning must be social or team-based. In a variety of learning contexts, individual work is important. It may well be that Net Gen students' strengths are also their weaknesses. The expectation for fast-paced, rapidly shifting interaction coupled with a relatively short attention span may be counterproductive in many learning contexts. Repetition and steady, patient practice—key to some forms of mastery—may prove difficult for Net Gen students. Designing courses for them necessitates balancing these strengths and weaknesses.
  • We should not neglect the informal for the formal, or assume that Net Gen students somehow will figure out the virtual space on their own. We should connect what happens in the classroom with what happens in informal and virtual spaces.
  • Simply installing wireless access points and fresh carpeting isn't enough if done in isolation; such improvements pay real dividends only if they are in concert with the institution's overall teaching and learning objectives. It is the vision that generates the design principles that will, in turn, be used to make key decisions about how learning spaces are configured.
  • The vision and design principles should emphasize the options students have as active participants in the learning process. Design principles should include terms such as analyze, create, criticize, debate, present, and classify—all directed at what the space enables the students to do. For example, students should be able to present materials to the class. Outside class, they should have access to applications and materials that directly support analysis of data, text, and other media. Forums for discussion and critical debate, both real and virtual, are key to encouraging learning and will be looked for by Net Gen students.
  • Learning spaces should accommodate the use of as many kinds of materials as possible and enable the display of and access to those materials by all participants. Learning space needs to provide the participants—instructors and students alike—with interactive tools that enable exploration, probing, and examination. This might include a robust set of applications installed on the computer that controls the room's displays, as well as a set of communication tools. Since the process of examination and debate leads to discovery and the construction of new knowledge, it could be important to equip spaces with devices that can capture classroom discussion and debate, which can be distributed to all participants for future reference and study.
  • the end of the class meeting marks a transition from one learning mode to another.
  • This lecture hall is of relatively recent vintage; its seats and paired tables make it much easier to deploy and use her "tools," which include printouts of the day's reading, as well as a small laptop computer. Her fellow students are doing likewise. Each of them is using some device to access the course's Web site—some with laptops, others with tablet computers, still others with handheld computers. Using wireless connections, they all access the course's Web site and navigate to the site's "voting" page.
  • a "magic wand," a radio-frequency controller that enables her to operate her computer—as well as many of the classroom's functions—wirelessly, from any point in the room. She can capture anything she writes on the blackboard and make it available to her students on the course Web site. Freed from needing to take extensive notes, the students are able to participate more fully in the class discussion. Finally, the professor is carrying a small recorder that captures her lecture, digitizes the audio, and uploads it to the course Web site for the students to review when they prepare for finals.
  • Sandra launches the classroom's screen sharing application. Within a few seconds, her computer's screen is projected on the room's main screen. The class discussion focuses on this diagram, and the professor, using a virtual pencil, is able to make notes on the diagram. The diagram and notes are captured and placed on the class Web site for review.
  • Soon the debate gets stuck; the students can't resolve the issue. The professor goes to the podium, types briefly, and then asks the students to go to a URL to see a question and to choose the answer they feel is correct. The students access the Web page from laptops, handhelds, or wireless IP-based phones. In two minutes they have completed the poll and submitted their responses. The results are quickly tabulated and displayed. The wide diversity of opinion surprises everyone. The professor reframes the issue, without giving the answer, and the students continue to discuss it. She repeats the poll; this time there is more agreement among the students, enabling her to move the discussion forward.

      Could you see being able to do this? Would this work for you?
  • She goes to the podium computer and clicks on a few links, and soon a videoconferencing session is displayed on the right-hand screen. She has arranged to have a colleague of hers "drop in" on the class to discuss a point that is in the colleague's particular area of expertise. The class has a conversation with the expert, who is at large research institution more than 500 miles away. Students listen to the expert's comments and are able to pose questions using one of the three cordless microphones available to the class. On the left-hand screen, the visiting professor shows some images and charts that help explain the concepts under discussion.
  • the other students in her class have signed up for most of the slots, conferring with friends using chat programs to ensure that they sign up for the same lab slots.
  • The discussion pocket is the college's term for a small, curved space with a table and bench to accommodate a meeting of four or five people. Found outside the newer classrooms, they are handy for informal, spontaneous discussions. Sandra's group moves into the pocket and for the next 15 minutes continue their "spill over" discussion of the class.

      How does this change perceptions of when and where learning begins and ends?
  • hey are able to have an audio chat; Sandra's friend is in her dorm room, and Sandra is in a remote corner of the library where conversation will not disturb others. As their discussion progresses, they go to the course's Web site and launch the virtual whiteboard to diagram some concepts. They develop a conceptual diagram—drawing, erasing, and revising it until they agree the diagram is correct. They both download a copy. Sandra volunteers to work on polishing the diagram and will leave a copy of the final diagram in her share folder in her online portfolio "locker
  • The underlying theme remains the same, however: cultivating learning practices consistent with learning theory and aligned with the habits and expectations of Net Gen students
  • For most higher education institutions, the lecture hall will not disappear; the challenge is to develop a new generation of lecture hall, one that enables Net Gen students and faculty to engage in enlivened, more interactive experiences. If the lecture hall is integrated with other spaces—physically as well as virtually—it will enable participants to sustain the momentum from the class session into other learning contexts. The goal is not to do away with the traditional classroom, but rather to reinvent and to integrate it with the other learning spaces, moving toward a single learning environment.
  • Learning theory is central to any consideration of learning spaces; colleges and universities cannot afford to invest in "fads" tailored to the Net Gen student that might not meet the needs of the next generation.
  • For example, start with the Net Gen students' focus on goals and achievement. That achievement orientation ties to learning theory's emphasis on metacognition, where learners assess their progress and make active decisions to achieve learning goals. Learning space design could support this by providing contact with people who can provide feedback: tutors, consultants, and faculty. This could, in turn, be supported in the IT environment by making formative self-tests available, as well as an online portfolio, which would afford students the opportunity to assess their overall academic progress.
  • As institutions create an anywhere, anytime IT infrastructure, opportunities arise to tear down silos and replace them with a more ubiquitous learning environment. Using laptops and other networked devices, students and faculty are increasingly able to carry their entire working environment with them. To capitalize on this, campus organizations must work collaboratively to create a more integrated work environment for the students and faculty, one that better serves the mobile Net Gen students as well as a faculty faced with the initial influx of these students into their ranks
  • One of the key variables is the institution itself. Learning spaces are institutional in scope—their implementation involves the institution's culture, tradition, and mission.
  • The starting point for rethinking learning spaces to support Net Gen students begins with an underlying vision for the learning activities these spaces should support. This vision should be informed by learning theory, as well as by recognition of the characteristics of the students and faculty who use these spaces.

Hearing Bilingual - How Babies Tell Languages Apart - NYTimes.com - 0 views

  • “What the study demonstrates is that the variability in bilingual babies’ experience keeps them open,” said Dr. Patricia Kuhl, co-director of the Institute for Learning and Brain Sciences at the University of Washington and one of the authors of the study. “They do not show the perceptual narrowing as soon as monolingual babies do. It’s another piece of evidence that what you experience shapes the brain.
  • In one recent study, Dr. Werker and her collaborators showed that babies born to bilingual mothers not only prefer both of those languages over others — but are also able to register that the two languages are different.
  • Over the past decade, Ellen Bialystok, a distinguished research professor of psychology at York University in Toronto, has shown that bilingual children develop crucial skills in addition to their double vocabularies, learning different ways to solve logic problems or to handle multitasking, skills that are often considered part of the brain’s so-called executive function.

  • These higher-level cognitive abilities are localized to the frontal and prefrontal cortex in the brain. “Overwhelmingly, children who are bilingual from early on have precocious development of executive function,” Dr. Bialystok said.
  • Dr. Kuhl calls bilingual babies “more cognitively flexible” than monolingual infants.
  • “This special mapping that babies seem to do with language happens in a social setting,” Dr. Kuhl said. “They need to be face to face, interacting with other people. The brain is turned on in a unique way.”

    One of the key take aways for me is this quote: "This special mapping that babies seem to do with language happens in a social setting," Dr. Kuhl said. "They need to be face to face, interacting with other people. The brain is turned on in a unique way."
