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.
