most profound impact of the Internet, an impact that has yet to be fully realized, is its ability to support and expand the various aspects of social learning. What do we mean by “social learning”? Perhaps the simplest way to explain this concept is to note that social learning is based on the premise that our understanding of content is socially constructed through conversations about that content and through grounded interactions, especially with others, around problems or actions. The focus is not so much on what we are learning but on how we are learning.5

This perspective shifts the focus of our attention from the content of a subject to the learning activities and human interactions around which that content is situated. This perspective also helps to explain the effectiveness of study groups. Students in these groups can ask questions to clarify areas of uncertainty or confusion, can improve their grasp of the material by hearing the answers to questions from fellow students, and perhaps most powerfully, can take on the role of teacher to help other group members benefit from their understanding (one of the best ways to learn something is, after all, to teach it to others).

This encourages the practice of what John Dewey called “productive inquiry”—that is, the process of seeking the knowledge when it is needed in order to carry out a particular situated task.

ecoming a trusted contributor to Wikipedia involves a process of legitimate peripheral participation that is similar to the process in open source software communities. Any reader can modify the text of an entry or contribute new entries. But only more experienced and more trusted individuals are invited to become “administrators” who have access to higher-level editing tools.8

by clicking on tabs that appear on every page, a user can easily review the history of any article as well as contributors’ ongoing discussion of and sometimes fierce debates around its content, which offer useful insights into the practices and standards of the community that is responsible for creating that entry in Wikipedia. (In some cases, Wikipedia articles start with initial contributions by passionate amateurs, followed by contributions from professional scholars/researchers who weigh in on the “final” versions. Here is where the contested part of the material becomes most usefully evident.) In this open environment, both the content and the process by which it is created are equally visible, thereby enabling a new kind of critical reading—almost a new form of literacy—that invites the reader to join in the consideration of what information is reliable and/or important.

But viewing learning as the process of joining a community of practice reverses this pattern and allows new students to engage in “learning to be” even as they are mastering the content of a field.

Mastering a field of knowledge involves not only “learning about” the subject matter but also “learning to be” a full participant in the field. This involves acquiring the practices and the norms of established practitioners in that field or acculturating into a community of practice.

Another interesting experiment in Second Life was the Harvard Law School and Harvard Extension School fall 2006 course called “CyberOne: Law in the Court of Public Opinion.” The course was offered at three levels of participation. First, students enrolled in Harvard Law School were able to attend the class in person. Second, non–law school students could enroll in the class through the Harvard Extension School and could attend lectures, participate in discussions, and interact with faculty members during their office hours within Second Life. And at the third level, any participant in Second Life could review the lectures and other course materials online at no cost. This experiment suggests one way that the social life of Internet-based virtual education can coexist with and extend traditional education.

Digital StudyHall (DSH), which is designed to improve education for students in schools in rural areas and urban slums in India. The project is described by its developers as “the educational equivalent of Netflix + YouTube + Kazaa.”11 Lectures from model teachers are recorded on video and are then physically distributed via DVD to schools that typically lack well-trained instructors (as well as Internet connections). While the lectures are being played on a monitor (which is often powered by a battery, since many participating schools also lack reliable electricity), a “mediator,” who could be a local teacher or simply a bright student, periodically pauses the video and encourages engagement among the students by asking questions or initiating discussions about the material they are watching.

John King, the associate provost of the University of Michigan

For the past few years, he points out, incoming students have been bringing along their online social networks, allowing them to stay in touch with their old friends and former classmates through tools like SMS, IM, Facebook, and MySpace. Through these continuing connections, the University of Michigan students can extend the discussions, debates, bull sessions, and study groups that naturally arise on campus to include their broader networks. Even though these extended connections were not developed to serve educational purposes, they amplify the impact that the university is having while also benefiting students on campus.14 If King is right, it makes sense for colleges and universities to consider how they can leverage these new connections through the variety of social software platforms that are being established for other reasons.

The project’s website includes reports of how students, under the guidance of professional astronomers, are using the Faulkes telescopes to make small but meaningful contributions to astronomy.

“This is not education in which people come in and lecture in a classroom. We’re helping students work with real data.”16

HOU invites students to request observations from professional observatories and provides them with image-processing software to visualize and analyze their data, encouraging interaction between the students and scientists

The site is intended to serve as “an open forum for worldwide discussions on the Decameron and related topics.” Both scholars and students are invited to submit their own contributions as well as to access the existing resources on the site. The site serves as an apprenticeship platform for students by allowing them to observe how scholars in the field argue with each other and also to publish their own contributions, which can be relatively small—an example of the “legitimate peripheral participation” that is characteristic of open source communities. This allows students to “learn to be,” in this instance by participating in the kind of rigorous argumentation that is generated around a particular form of deep scholarship. A community like this, in which students can acculturate into a particular scholarly practice, can be seen as a virtual “spike”: a highly specialized site that can serve as a global resource for its field.

I posted a list of links to all the student blogs and mentioned the list on my own blog. I also encouraged the students to start reading one another's writing. The difference in the writing that next week was startling. Each student wrote significantly more than they had previously. Each piece was more thoughtful. Students commented on each other's writing and interlinked their pieces to show related or contradicting thoughts. Then one of the student assignments was commented on and linked to from a very prominent blogger. Many people read the student blogs and subscribed to some of them. When these outside comments showed up, indicating that the students really were plugging into the international community's discourse, the quality of the writing improved again. The power of peer review had been brought to bear on the assignments.17

for any topic that a student is passionate about, there is likely to be an online niche community of practice of others who share that passion.

Finding and joining a community that ignites a student’s passion can set the stage for the student to acquire both deep knowledge about a subject (“learning about”) and the ability to participate in the practice of a field through productive inquiry and peer-based learning (“learning to be”). These communities are harbingers of the emergence of a new form of technology-enhanced learning—Learning 2.0—which goes beyond providing free access to traditional course materials and educational tools and creates a participatory architecture for supporting communities of learners.

We need to construct shared, distributed, reflective practicums in which experiences are collected, vetted, clustered, commented on, and tried out in new contexts.

An example of such a practicum is the online Teaching and Learning Commons (http://commons.carnegiefoundation.org/) launched earlier this year by the Carnegie Foundation for the Advancement of Teaching

The Commons is an open forum where instructors at all levels (and from around the world) can post their own examples and can participate in an ongoing conversation about effective teaching practices, as a means of supporting a process of “creating/using/re-mixing (or creating/sharing/using).”20

The original World Wide Web—the “Web 1.0” that emerged in the mid-1990s—vastly expanded access to information. The Open Educational Resources movement is an example of the impact that the Web 1.0 has had on education.

But the Web 2.0, which has emerged in just the past few years, is sparking an even more far-reaching revolution. Tools such as blogs, wikis, social networks, tagging systems, mashups, and content-sharing sites are examples of a new user-centric information infrastructure that emphasizes participation (e.g., creating, re-mixing) over presentation, that encourages focused conversation and short briefs (often written in a less technical, public vernacular) rather than traditional publication, and that facilitates innovative explorations, experimentations, and purposeful tinkerings that often form the basis of a situated understanding emerging from action, not passivity.

In the twentieth century, the dominant approach to education focused on helping students to build stocks of knowledge and cognitive skills that could be deployed later in appropriate situations. This approach to education worked well in a relatively stable, slowly changing world in which careers typically lasted a lifetime. But the twenty-first century is quite different.

We now need a new approach to learning—one characterized by a demand-pull rather than the traditional supply-push mode of building up an inventory of knowledge in students’ heads. Demand-pull learning shifts the focus to enabling participation in flows of action, where the focus is both on “learning to be” through enculturation into a practice as well as on collateral learning.

The demand-pull approach is based on providing students with access to rich (sometimes virtual) learning communities built around a practice. It is passion-based learning, motivated by the student either wanting to become a member of a particular community of practice or just wanting to learn about, make, or perform something. Often the learning that transpires is informal rather than formally conducted in a structured setting. Learning occurs in part through a form of reflective practicum, but in this case the reflection comes from being embedded in a community of practice that may be supported by both a physical and a virtual presence and by collaboration between newcomers and professional practitioners/scholars.

The building blocks provided by the OER movement, along with e-Science and e-Humanities and the resources of the Web 2.0, are creating the conditions for the emergence of new kinds of open participatory learning ecosystems23 that will support active, passion-based learning: Learning 2.0.

As a graduate student at UC-Berkeley in the late 1970s, Treisman worked on the poor performance of African-Americans and Latinos in undergraduate calculus classes. He discovered the problem was not these students’ lack of motivation or inadequate preparation but rather their approach to studying. In contrast to Asian students, who, Treisman found, naturally formed “academic communities” in which they studied and learned together, African-Americans tended to separate their academic and social lives and studied completely on their own. Treisman developed a program that engaged these students in workshop-style study groups in which they collaborated on solving particularly challenging calculus problems. The program was so successful that it was adopted by many other colleges. See Uri Treisman, “Studying Students Studying Calculus: A Look at the Lives of Minority Mathematics Students in College,” College Mathematics Journal, vol. 23, no. 5 (November 1992), pp. 362–72, http://math.sfsu.edu/hsu/workshops/treisman.html.

In the early 1970s, Stanford University Professor James Gibbons developed a similar technique, which he called Tutored Videotape Instruction (TVI). Like DSH, TVI was based on showing recorded classroom lectures to groups of students, accompanied by a “tutor” whose job was to stop the tape periodically and ask questions. Evaluations of TVI showed that students’ learning from TVI was as good as or better than in-classroom learning and that the weakest students academically learned more from participating in TVI instruction than from attending lectures in person. See J. F. Gibbons, W. R. Kincheloe, and S. K. Down, “Tutored Video-tape Instruction: A New Use of Electronics Media in Education,” Science, vol. 195 (1977), pp. 1136–49.

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.

Over time, this collective learning results in practices that reflect both the pursuit of our enterprises and the attendant social relations. These practices are thus the property of a kind of community created over time by the sustained pursuit of a shared enterprise. It makes sense, therefore to call these kinds of communities communities of practice. (Wenger 1998: 45)

Rather than looking to learning as the acquisition of certain forms of knowledge, Jean Lave and Etienne Wenger have tried to place it in social relationships – situations of co-participation.

The fact that they are organizing around some particular area of knowledge and activity gives members a sense of joint enterprise and identity. For a community of practice to function it needs to generate and appropriate a shared repertoire of ideas, commitments and memories. It also needs to develop various resources such as tools, documents, routines, vocabulary and symbols that in some way carry the accumulated knowledge of the community.

The interactions involved, and the ability to undertake larger or more complex activities and projects though cooperation, bind people together and help to facilitate relationship and trust

The characteristics of communities of practice According to Etienne Wenger (c 2007), three elements are crucial in distinguishing a community of practice from other groups and communities: The domain. A community of practice is is something more than a club of friends or a network of connections between people. 'It has an identity defined by a shared domain of interest. Membership therefore implies a commitment to the domain, and therefore a shared competence that distinguishes members from other people' (op. cit.). The community. 'In pursuing their interest in their domain, members engage in joint activities and discussions, help each other, and share information. They build relationships that enable them to learn from each other' (op. cit.). The practice. 'Members of a community of practice are practitioners. They develop a shared repertoire of resources: experiences, stories, tools, ways of addressing recurring problems—in short a shared practice. This takes time and sustained interaction' (op. cit.).

Initially people have to join communities and learn at the periphery. The things they are involved in, the tasks they do may be less key to the community than others.

One of the implications for schools, as Barbara Rogoff and her colleagues suggest is that they must prioritize 'instruction that builds on children's interests in a collaborative way'. Such schools need also to be places where 'learning activities are planned by children as well as adults, and where parents and teachers not only foster children's learning but also learn from their own involvement with children' (2001: 3). Their example in this area have particular force as they are derived from actual school practice.

It not so much that learners acquire structures or models to understand the world, but they participate in frameworks that that have structure. Learning involves participation in a community of practice. And that participation 'refers not just to local events of engagement in certain activities with certain people, but to a more encompassing process of being active participants in the practices of social communities and constructing identities in relation to these communities' (Wenger 1999: 4).

What is more, and in contrast with learning as internalization, ‘learning as increasing participation in communities of practice concerns the whole person acting in the world’ (Lave and Wenger 1991: 49). The focus is on the ways in which learning is ‘an evolving, continuously renewed set of relations’ (ibid.: 50). In other words, this is a relational view of the person and learning (see the discussion of selfhood).

'the purpose is not to learn from talk as a substitute for legitimate peripheral participation; it is to learn to talk as a key to legitimate peripheral participation'. This orientation has the definite advantage of drawing attention to the need to understand knowledge and learning in context. However, situated learning depends on two claims: It makes no sense to talk of knowledge that is decontextualized, abstract or general. New knowledge and learning are properly conceived as being located in communities of practice (Tennant 1997: 77).

There is a risk, as Jean Lave and Etienne Wenger acknowledge, of romanticizing communities of practice.

'In their eagerness to debunk testing, formal education and formal accreditation, they do not analyse how their omission [of a range of questions and issues] affects power relations, access, public knowledge and public accountability' (Tennant 1997: 79).

Perhaps the most helpful of these explorations is that of Barbara Rogoff and her colleagues (2001). They examine the work of an innovative school in Salt Lake City and how teachers, students and parents were able to work together to develop an approach to schooling based around the principle that learning 'occurs through interested participation with other learners'.

Learning is in the relationships between people. As McDermott (in Murphy 1999:17) puts it: Learning traditionally gets measured as on the assumption that it is a possession of individuals that can be found inside their heads… [Here] learning is in the relationships between people. Learning is in the conditions that bring people together and organize a point of contact that allows for particular pieces of information to take on a relevance; without the points of contact, without the system of relevancies, there is not learning, and there is little memory. Learning does not belong to individual persons, but to the various conversations of which they are a part.

Learning is, thus, not seen as the acquisition of knowledge by individuals so much as a process of social participation. The nature of the situation impacts significantly on the process.

there must be a minimum of 5 public pictures in the account in order to start this review process.

If they are real pictures, the public photos in the account are added to the pool of pictures in flickr searches and RSS feeds.

In the course of looking for the pictures and creating the annotated hot spots they will be thinking about the material covered in a new way and strengthening the mental links to the concepts they have learned. I hope to make their learning sticky.

reating digital mind maps of the material we learned way back at the beginning of the semester.

At exam time they can review all the annotated pictures in the pool made by themselves and their classmates. They will be teaching and learning from each other.

They can use the pictures in projects, assignments and blog posts. I will also be able to use them the next time I teach the course to benefit the next group of students. They will be teaching people they have never met. They are also building a permanent resource collection.

They are talking to other students and teachers in the building about this. A buzz is growing. Can you imagine the conversations they are having at home? They are involving their families and friends in their learning.

As pictures began to come up in public searches on flickr for each of the unique course tags, I created a flickr badge (you'll have to "sign in" to follow that link) for each class. I put it in each blog's sidebar under the heading "Our Math Photo Gallery." The engine behind the badges is the RSS feed associated with each unique course tag. Flickr generates these RSS feeds automatically.

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

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?

Amateur cinematographers and musicians use hosting sites to reach a broader audience for their work and to build a network of fans. Increasingly, learning organizations, faculty, scholars, and students are using these tools as well, and in the coming year, it is very likely that such practice will enter the mainstream of use in these institutions.
