The Earth becomes a chalkboard, a spreadsheet, a presentation medium, where the thorny problems of global civilization and its discontents can be explored out in exquisite detail. In this sense, no problem, no matter how vast, no matter how global, will be seen as being beyond the reach of these children. They’ll learn this – not because of what teacher says, or what homework assignments they complete – through interaction with the technology itself.

We and our technological-materialist culture have fostered an environment of such tremendous novelty and variety that we have changed the equations of childhood.

As it turns out (and there are numerous examples to support this) a mobile handset is probably the most important tool someone can employ to improve their economic well-being. A farmer can call ahead to markets to find out which is paying the best price for his crop; the same goes for fishermen. Tradesmen can close deals without the hassle and lost time involved in travel; craftswomen can coordinate their creative resources with a few text messages. Each of these examples can be found in any Bangladeshi city or Africa village.

The sharing of information is an innate human behavior: since we learned to speak we’ve been talking to each other, warning each other of dangers, informing each other of opportunities, positing possibilities, and just generally reassuring each other with the sound of our voices. We’ve now extended that four-billion-fold, so that half of humanity is directly connected, one to another.

Everything we do, both within and outside the classroom, must be seen through this prism of sharing. Teenagers log onto video chat services such as Skype, and do their homework together, at a distance, sharing and comparing their results. Parents offer up their kindergartener’s presentations to other parents through Twitter – and those parents respond to the offer. All of this both amplifies and undermines the classroom. The classroom has not dealt with the phenomenal transformation in the connectivity of the broader culture, and is in danger of becoming obsolesced by it.

We already live in a time of disconnect, where the classroom has stopped reflecting the world outside its walls. The classroom is born of an industrial mode of thinking, where hierarchy and reproducibility were the order of the day. The world outside those walls is networked and highly heterogeneous. And where the classroom touches the world outside, sparks fly; the classroom can’t handle the currents generated by the culture of connectivity and sharing. This can not go on.

We must accept the reality of the 21st century, that, more than anything else, this is the networked era, and that this network has gifted us with new capabilities even as it presents us with new dangers. Both gifts and dangers are issues of potency; the network has made us incredibly powerful. The network is smarter, faster and more agile than the hierarchy; when the two collide – as they’re bound to, with increasing frequency – the network always wins.

A text message can unleash revolution, or land a teenager in jail on charges of peddling child pornography, or spark a riot on a Sydney beach; Wikipedia can drive Britannica, a quarter millennium-old reference text out of business; a outsider candidate can get himself elected president of the United States because his team masters the logic of the network. In truth, we already live in the age of digital citizenship, but so many of us don’t know the rules, and hence, are poor citizens.

before a child is given a computer – either at home or in school – it must be accompanied by instruction in the power of the network. A child may have a natural facility with the network without having any sense of the power of the network as an amplifier of capability. It’s that disconnect which digital citizenship must bridge.

Let us instead focus on how we will use technology in fifty years’ time. We can already see the shape of the future in one outstanding example – a website known as RateMyProfessors.com. Here, in a database of nine million reviews of one million teachers, lecturers and professors, students can learn which instructors bore, which grade easily, which excite the mind, and so forth. This simple site – which grew out of the power of sharing – has radically changed the balance of power on university campuses throughout the US and the UK.

Alongside the rise of RateMyProfessors.com, there has been an exponential increase in the amount of lecture material you can find online, whether on YouTube, or iTunes University, or any number of dedicated websites. Those lectures also have ratings, so it is already possible for a student to get to the best and most popular lectures on any subject, be it calculus or Mandarin or the medieval history of Europe.

As the university dissolves in the universal solvent of the network, the capacity to use the network for education increases geometrically; education will be available everywhere the network reaches. It already reaches half of humanity; in a few years it will cover three-quarters of the population of the planet. Certainly by 2060 network access will be thought of as a human right, much like food and clean water.

Educators will continue to collaborate, but without much of the physical infrastructure we currently associate with educational institutions. Classrooms will self-organize and disperse organically, driven by need, proximity, or interest, and the best instructors will find themselves constantly in demand. Life-long learning will no longer be a catch-phrase, but a reality for the billions of individuals all focusing on improving their effectiveness within an ever-more-competitive global market for talent.

learning management systems (Exhibit 1).

The reality, however, is that today's students demand greater control of their own learning and the inclusion of technologies in ways that meet their needs and preferences (Prensky 2005)

Tools like blogs, wikis, media-sharing applications, and social networking sites can support and encourage informal conversation, dialogue, collaborative content generation, and knowledge sharing, giving learners access to a wide range of ideas and representations. Used appropriately, they promise to make truly learner-centered education a reality by promoting learner agency, autonomy, and engagement in social networks that straddle multiple real and virtual communities by reaching across physical, geographic, institutional, and organizational boundaries.

"I have always imagined the information space as something to which everyone has immediate and intuitive access, and not just to browse, but to create” (2000, 216). Social software tools make it easy to contribute ideas and content, placing the power of media creation and distribution into the hands of "the people formerly known as the audience" (Rosen 2006).

the most promising settings for a pedagogy that capitalizes on the capabilities of these tools are fully online or blended so that students can engage with peers, instructors, and the community in creating and sharing ideas. In this model, some learners engage in creative authorship, producing and manipulating digital images and video clips, tagging them with chosen keywords, and making this content available to peers worldwide through Flickr, MySpace, and YouTube

Student-centered tasks designed by constructivist teachers reach toward this ideal, but they too often lack the dimension of real-world interactivity and community engagement that social software can contribute.

Pedagogy 2.0: Teaching and Learning for the Knowledge Age In striving to achieve these goals, educators need to revisit their conceptualization of teaching and learning (Exhibit 2).

Pedagogy 2.0: Teaching and Learning for the Knowledge Age In striving to achieve these goals, educators need to revisit their conceptualization of teaching and learning

Pedagogy 2.0 is defined by: Content: Microunits that augment thinking and cognition by offering diverse perspectives and representations to learners and learner-generated resources that accrue from students creating, sharing, and revising ideas; Curriculum: Syllabi that are not fixed but dynamic, open to negotiation and learner input, consisting of bite-sized modules that are interdisciplinary in focus and that blend formal and informal learning;Communication: Open, peer-to-peer, multifaceted communication using multiple media types to achieve relevance and clarity;Process: Situated, reflective, integrated thinking processes that are iterative, dynamic, and performance and inquiry based;Resources: Multiple informal and formal sources that are rich in media and global in reach;Scaffolds: Support for students from a network of peers, teachers, experts, and communities; andLearning tasks: Authentic, personalized, learner-driven and learner-designed, experiential tasks that enable learners to create content.

Instructors implementing Pedagogy 2.0 principles will need to work collaboratively with learners to review, edit, and apply quality assurance mechanisms to student work while also drawing on input from the wider community outside the classroom or institution (making use of the "wisdom of crowds” [Surowiecki 2004]).

A small portion of student performance content—if it is new knowledge—will be useful to keep. Most of the student performance content will be generated, then used, and will become stored in places that will never again see the light of day. Yet . . . it is still important to understand that the role of this student content in learning is critical.

This understanding of student-generated content is also consistent with the constructivist view that acknowledges the learner as the chief architect of knowledge building. From this perspective, learners build or negotiate meaning for a concept by being exposed to, analyzing, and critiquing multiple perspectives and by interpreting these perspectives in one or more observed or experienced contexts

This understanding of student-generated content is also consistent with the constructivist view that acknowledges the learner as the chief architect of knowledge building. From this perspective, learners build or negotiate meaning for a concept by being exposed to, analyzing, and critiquing multiple perspectives and by interpreting these perspectives in one or more observed or experienced contexts. In so doing, learners generate their own personal rules and knowledge structures, using them to make sense of their experiences and refining them through interaction and dialogue with others.

Other divides are evident. For example, the social networking site Facebook is now the most heavily trafficked Web site in the United States with over 8 million university students connected across academic communities and institutions worldwide. The majority of Facebook participants are students, and teachers may not feel welcome in these communities. Moreover, recent research has shown that many students perceive teaching staff who use Facebook as lacking credibility as they may present different self-images online than they do in face-to-face situations (Mazer, Murphy, and Simonds 2007). Further, students may perceive instructors' attempts to coopt such social technologies for educational purposes as intrusions into their space. Innovative teachers who wish to adopt social software tools must do so with these attitudes in mind.

"students want to be able to take content from other people. They want to mix it, in new creative ways—to produce it, to publish it, and to distribute it"

Furthermore, although the advent of Web 2.0 and the open-content movement significantly increase the volume of information available to students, many higher education students lack the competencies necessary to navigate and use the overabundance of information available, including the skills required to locate quality sources and assess them for objectivity, reliability, and currency

In combination with appropriate learning strategies, Pedagogy 2.0 can assist students in developing such critical thinking and metacognitive skills (Sener 2007; McLoughlin, Lee, and Chan 2006).

We envision that social technologies coupled with a paradigm of learning focused on knowledge creation and community participation offer the potential for radical and transformational shifts in teaching and learning practices, allowing learners to access peers, experts, and the wider community in ways that enable reflective, self-directed learning.

. By capitalizing on personalization, participation, and content creation, existing and future Pedagogy 2.0 practices can result in educational experiences that are productive, engaging, and community based and that extend the learning landscape far beyond the boundaries of classrooms and educational institutions.
