Perhaps the most important breakthrough was Google's willingness to relinquish control of the user-end of the transaction, instead of trying to lock them in with proprietary technology and restrictive licensing

O'Reilly took a second Web 2.0 principle from Peer-to-Peer pioneer BitTorrent, which works by completely decentralising the delivery of files, with every client also functioning as a server. The more popular a file, is, the faster it can be served, since there are more users providing bandwidth and fragments of the file. Thus, "the service automatically gets better the more people use it".

Taking another model from open source, users are treated as "co-developers", actively encouraged to contribute, and monitored in real time to see what they are using, and how they are using it.

"Until Web 2.0 the learning curve to creating websites was quite high, complex, and a definite barrier to entry," says the third of our triumvirate of Tims, Tim Bray, director of Web Technologies at Sun Microsystems.

Web 2.0 takes some of its philosophical underpinning from James Surowiecki's book The Wisdom of Crowds, which asserts that the aggregated insights of large groups of diverse people can provide better answers and innovations than individual experts.

In practice, even fewer than 1% of people may be making a useful contribution - but these may be the most energetic and able members of a very large community. In 2006 1,000 people, just 0.003% of its users, contributed around two-thirds of Wikipedia's edits.

Ajax speeds up response times by enabling just part of a page to be updated, instead of downloading a whole new page. Nielsen's objections include that this breaks the "back" button - the ability to get back to where you've been, which Nielsen says is the second most used feature in Web navigation.

"Everybody who has a Web browser has got that platform," says Berners-Lee, in a podcast available on IBM's developerWorks site. "So the nice thing about it is when you do code up an Ajax implementation, other people can take it and play with it."

Web 2.0 is a step on the way to the Semantic Web, a long-standing W3C initiative to create a standards-based framework able to understand the links between data which is related in the real world, and follow that data wherever it resides, regardless of application and database boundaries.

The problem with Web 2.0, Pemberton says, is that it "partitions the web into a number of topical sub-webs, and locks you in, thereby reducing the value of the network as a whole."

How do you decide which social networking site to join? he asks. "Do you join several and repeat the work?" With the Semantic Web's Resource Description Framework (RDF), you won't need to sign up to separate networks, and can keep ownership of your data. "You could describe it as a CSS for meaning: it allows you to add a small layer of markup to your page that adds machine-readable semantics."

The problems with Web 2.0 lock-in which Pemberton describes, were illustrated when a prominent member of the active 1%, Robert Scoble, ran a routine called Plaxo to try to extract details of his 5,000 contacts from Facebook, in breach of the site's terms of use, and had his account disabled. Although he has apparently had his account reinstated, the furore has made the issue of Web 2.0 data ownership and portability fiercely topical.

when Google announced its OpenSocial set of APIs, which will enable developers to create portable applications and bridges between social networking websites, Facebook was not among those taking part. Four years after O'Reilly attempted to define Web 2.0, Google, it seems, remains the standard-bearer, while others are forgetting what it was supposed to be about.

This immersion in virtual environments and augmented realities shapes participants' learning styles beyond what using sophisticated computers and telecommunications has fostered thus far, with multiple implications for higher education.

Beyond actional and symbolic immersion, advances in interface technology are now creating virtual environments and augmented realities that induce a psychological sense of sensory and physical immersion.

The research on virtual reality Salzman and I conducted on frames of reference found that the exocentric and the egocentric FORs have different strengths for learning. Our studies established that learning ideally involves a "bicentric" perspective alternating between egocentric and exocentric FORs.

But what is so special about the egocentric perspectives and situated learning now enabled by emerging media? After all, each of us lives with an egocentric perspective in the real world and has many opportunities for situated learning without using technology. One attribute that makes mediated immersion different and powerful is the ability to access information resources and psychosocial community distributed across distance and time, broadening and deepening experience. A second important attribute is the ability to create interactions and activities in mediated experience not possible in the real world, such as teleporting within a virtual environment, enabling a distant person to see a real-time image of your local environment, or interacting with a (simulated) chemical spill in a busy public setting. Both of these attributes are actualized in the Alice-in-Wonderland interface.

Notion of place is layered/blended/multiple; mobility and nomadicity prevalent among dispersed, fragmented, fluctuating habitats (for example, coffeehouses near campus)

Guided social constructivism and situated learning as major forms of pedagogy

he defining quality of a learning community is that there is a culture of learning, in which everyone is involved in a collective effort of understanding. There are four characteristics that such a culture must have: (1) diversity of expertise among its members, who are valued for their contributions and given support to develop, (2) a shared objective of continually advancing the collective knowledge and skills, (3) an emphasis on learning how to learn, and (4) mechanisms for sharing what is learned. If a learning community is presented with a problem, then the learning community can bring its collective knowledge to bear on the problem. It is not necessary that each member assimilate everything that the community knows, but each should know who within the community has relevant expertise to address any problem. This is a radical departure from the traditional view of schooling, with its emphasis on individual knowledge and performance, and the expectation that students will acquire the same body of knowledge at the same time.26

Peer-developed and peer-rated forms of assessment complement faculty grading, which is often based on individual accomplishment in a team performance context  Assessments provide formative feedback on instructional effectiveness

Multipurpose habitats—creating layered/blended/personalizable places rather than specialized locations (such as computer labs)

o the extent that some of these ideas about neomillennial learning styles are accurate, campuses that make strategic investments in physical plant, technical infrastructure, and professional development along the dimensions suggested will gain a considerable competitive advantage in both recruiting top students and teaching them effectively.

Net Generation learning styles stem primarily from the world-to-the-desktop interface; however, the growing prevalence of interfaces to virtual environments and augmented realities is beginning to foster so-called neomillennial learning styles in users of all ages.

Immersion is the subjective impression that one is participating in a comprehensive, realistic experience.

Inducing a participant's symbolic immersion involves triggering powerful semantic associations via the content of an experience.

The capability of computer interfaces to foster psychological immersion enables technology-intensive educational experiences that draw on a powerful pedagogy: situated learning.

The major schools of thought cited are behaviorist theories of learning (presentational instruction), cognitivist theories of learning (tutoring and guided learning by doing), and situated theories of learning (mentoring and apprenticeships in communities of practice).

Situated learning requires authentic contexts, activities, and assessment coupled with guidance from expert modeling, mentoring, and "legitimate peripheral participation."8 As an example of legitimate peripheral participation, graduate students work within the laboratories of expert researchers, who model the practice of scholarship. These students interact with experts in research as well as with other members of the research team who understand the complex processes of scholarship to varying degrees. While in these laboratories, students gradually move from novice researchers to more advanced roles, with the skills and expectations for them evolving.

Potentially quite powerful, situated learning is much less used for instruction than behaviorist or cognitivist approaches. This is largely because creating tacit, relatively unstructured learning in complex real-world settings is difficult.

However, virtual environments and ubiquitous computing can draw on the power of situated learning by creating immersive, extended experiences with problems and contexts similar to the real world.9 In particular, MUVEs and real-world settings augmented with virtual information provide the capability to create problem-solving communities in which participants can gain knowledge and skills through interacting with other participants who have varied levels of skills, enabling legitimate peripheral participation driven by intrinsic sociocultural forces.

Situated learning is important in part because of the crucial issue of transfer. Transfer is defined as the application of knowledge learned in one situation to another situation and is demonstrated if instruction on a learning task leads to improved performance on a transfer task, typically a skilled performance in a real-world setting

Moreover, the evolution of an individual's or group's identity is an important type of learning for which simulated experiences situated in virtual environments or augmented realities are well suited. Reflecting on and refining an individual identity is often a significant issue for higher education students of all ages, and learning to evolve group and organizational identity is a crucial skill in enabling innovation and in adapting to shifting contexts.

Immersion is important in this process of identity exploration because virtual identity is unfettered by physical attributes such as gender, race, and disabilities.

Thanks to out-of-game trading of in-game items, Norrath, the virtual setting of the MMOG EverQuest, is the seventy-seventh largest economy in the real world, with a GNP per capita between that of Russia and Bulgaria. One platinum piece, the unit of currency in Norrath, trades on real world exchange markets higher than both the Yen and the Lira (Castronova, 2001).14

Multiple teams of students can access the MUVE simultaneously, each individual manipulating an avatar which is "sent back in time" to this virtual environment. Students must collaborate to share the data each team collects. Beyond textual conversation, students can project to each other "snapshots" of their current individual point of view (when someone has discovered an item of general interest) and also can "teleport" to join anyone on their team for joint investigation. Each time a team reenters the world, several months of time have passed in River City, so learners can track the dynamic evolution of local problems.

In our research on this educational MUVE based on situated learning, we are studying usability, student motivation, student learning, and classroom implementation issues. The results thus far are promising: All learners are highly motivated, including students typically unengaged in classroom settings. All students build fluency in distributed modes of communication and expression and value using multiple media because each empowers different types of communication, activities, experiences, and expressions. Even typically low-performing students can master complex inquiry skills and sophisticated content. Shifts in the pedagogy within the MUVE alter the pattern of student performance.

Research shows that many participants value this functionality and choose to access the Web page after leaving the museum.

Participants in these distributed simulations use location-aware handheld computers (with GPS technology), allowing users to physically move throughout a real-world location while collecting place-dependent simulated field data, interviewing virtual characters, and collaboratively investigating simulated scenarios.

Initial research on Environmental Detectives and other AR-based educational simulations demonstrates that this type of immersive, situated learning can effectively engage students in critical thinking about authentic scenarios.

Students were most effective in learning and problem-solving when they collectively sought, sieved, and synthesized experiences rather than individually locating and absorbing information from some single best source.

Rheingold's forecasts draw on lifestyles seen at present among young people who are high-end users of new media

Rather than having core identities defined through a primarily local set of roles and relationships, people would express varied aspects of their multifaceted identities through alternate extended experiences in distributed virtual environments and augmented realities.

one-third of U.S. households now have broadband access to the Internet. In the past three years, 14 million U.S. families have linked their computers with wireless home networks. Some 55 percent of Americans now carry cell phones

Mitchell's forecasts25 are similar to Rheingold's in many respects. He too envisions largely tribal lifestyles distributed across dispersed, fragmented, fluctuating habitats: electronic nomads wandering among virtual campfires. People's senses and physical agency are extended outward and into the intangible, at considerable cost to individual privacy. Individual identity is continuously reformed via an ever-shifting series of networking with others and with tools. People express themselves through nonlinear, associational webs of representations rather than linear "stories" and co-design services rather than selecting a precustomized variant from a menu of possibilities.

More and more, though, people of all ages will have lifestyles involving frequent immersion in both virtual and augmented reality. How might distributed, immersive media be designed specifically for education, and what neomillennial learning styles might they induce?

Mediated immersion creates distributed learning communities, which have different strengths and limits than location-bound learning communities confined to classroom settings and centered on the teacher and archival materials.27

Neomillenial Versus Millennial Learning Styles

Emphasis is placed on implications for strategic investments in physical plant, technology infrastructure, and professional development.

such as textbooks linked to course ratings by students)

Mirroring": Immersive virtual environments provide replicas of distant physical settings

Middleware, interoperability, open content, and open source

Finding information Sequential assimilation of linear information stream

Student products generally tests or papers Grading centers on individual performance

These ideas are admittedly speculative rather than based on detailed evidence and are presented to stimulate reaction and dialogue about these trends.

f we accept much of the analysis above

students of all ages with increasingly neomillennial learning styles will be drawn to colleges and universities that have these capabilities. Four implications for investments in professional development also are apparent. Faculty will increasingly need capabilities in:

Some of these shifts are controversial for many faculty; all involve "unlearning" almost unconscious beliefs, assumptions, and values about the nature of teaching, learning, and the academy. Professional development that requires unlearning necessitates high levels of emotional/social support in addition to mastering the intellectual/technical dimensions involved. The ideal form for this type of professional development is distributed learning communities so that the learning process is consistent with the knowledge and culture to be acquired. In other words, faculty must themselves experience mediated immersion and develop neomillennial learning styles to continue teaching effectively as the nature of students alters.

Differences among individuals are greater than dissimilarities between groups, so students in any age cohort will present a mixture of neomillennial, millennial, and traditional learning styles

The technologies discussed are emerging rather than mature, so their final form and influences on users are not fully understood. A substantial number of faculty and administrators will likely dismiss and resist some of the ideas and recommendations presented here.

With such specific applications of technology and the limited use of other forms (for example, multimedia), students' low expectations for the use of technology in the curriculum is not surprising. Such constrained use of technology by the faculty in the curriculum and low student expectations may serve to limit innovation and creativity as well as the faculty's capacity to engage students more deeply in their subject matter. Like all organizations, colleges and universities respond to the demands placed upon them. Students' and institutions' low expectations for the use of technology for learning provide insufficient impetus for faculties to change their behavior and make broader, more innovative use of these tools in the service of learning.

Consider this scenario:

From the beginning, however, a problem arose in that those middle school students went on to high schools and later to colleges that did not (and do not) provide this type of rich learning experience—a learning experience that can best be achieved when technology is used in the service of learning.

Data obtained from these sessions with high school and college seniors in Indiana, Oregon, and Virginia

Less attention has been given to how to help students achieve the desired learning outcomes through technology.

comparatively little support has been devoted to helping faculty use computers and other technologies in creative and innovative ways to deepen student learning.

To develop intentional learners, the curriculum must go beyond helping students gain knowledge for knowledge's sake to engaging students in the construction of knowledge for the sake of addressing the challenges faced by a complex, global society.

institutional structures and practices to resolve technical problems that faculty invariably encounter are very limited or are not the type of aid needed. Such lack of support limits the amount of time faculty can spend on what they do best—building a compelling curriculum and integrating technology for more powerful learning.

integrating study abroad into courses back on the home campus;

Faculty concerns perhaps center less on being "replaceable" and more on worrying that the teaching and learning enterprise will be reduced to students gathering information that can be easily downloaded, causing them to rely too heavily on technology instead of intellect.

First, traditional age students overwhelmingly prefer face-to-face contact with faculty to mediated communication. Second, technology used in the service of learning will require more—not less—sophistication on the part of students as they engage in processes of integration, translation, audience analysis, and critical judgment.

Faculty with expertise in one or more subjects, who have been exposed to what we know about how people learn, can determine how to enhance this learning through the use of technology. But simply understanding how to use technology will not provide the integration needed to reach the desired learning outcomes.

There is a need for integrating technology that is in the service of learning throughout the curriculum. More intentional use of technology to capture what students know and are able to integrate in their learning is needed.

There is an inexorable trend among college students to universal ownership, mobility, and access to technology.

Students were asked about the applications they used on their electronic devices. They reported that they use technology first for educational purposes, followed by communication.

presentation software was driven primarily by the requirements of the students' major and the curriculum.

Communications and entertainment are very much related to gender and age.

From student interviews, a picture emerged of student technology use driven by the demands of the major and the classes that students take. Seniors reported spending more time overall on a computer than do freshmen, and they reported greater use of a computer at a place of employment. Seniors spent more hours on the computer each week in support of their educational activities and also more time on more advanced applications—spreadsheets, presentations, and graphics.

Confirming what parents suspect, students with the lowest grade point averages (GPAs) spend significantly more time playing computer games; students with the highest GPAs spend more hours weekly using the computer in support of classroom activities. At the University of Minnesota, Crookston, students spent the most hours on the computer in support of classroom activities. This likely reflects the deliberate design of the curriculum to use a laptop extensively. In summary, the curriculum's technology requirements are major motivators for students to learn to use specialized software.

The interviews indicated that students are skilled with basic office suite applications but tend to know just enough technology functionality to accomplish their work; they have less in-depth application knowledge or problem solving skills.

According to McEuen, student technology skills can be likened to writing skills: Students come to college knowing how to write, but they are not developed writers. The analogy holds true for information technology, and McEuen suggested that colleges and universities approach information technology in the same way they approach writing.6

he major requires the development of higher-level skill sets with particular applications.

The comparative literature on student IT skill self-assessment suggests that students overrate their skills; freshmen overrate their skills more than seniors, and men overrate their skills more than women.7 Our data supports these conclusions. Judy Doherty, director of the Student Technologies Resource Group at Colgate University, remarked on student skill assessment, "Students state in their job applications that they are good if not very good, but when tested their skills are average to poor, and they need a lot of training."8

Mary Jane Smetanka of the Minneapolis–St. Paul Star Tribune reported that some students are so conditioned by punch-a-button problem solving on computers that they approach problems with a scattershot impulsiveness instead of methodically working them through. In turn, this leads to problem-solving difficulties.

We expected to find that the Net Generation student prefers classes that use technology. What we found instead is a bell curve with a preference for a moderate use of technology in the classroom (see Figure 1).

It is not surprising that if technology is used well by the instructor, students will come to appreciate its benefits.

A student's major was also an important predictor of preferences for technology in the classroom (see Table 3), with engineering students having the highest preference for technology in the classroom (67.8 percent), followed by business students (64.3 percent).

Humanities 7.7% 47.9% 40.2

he highest scores were given to improved communications, followed by factors related to the management of classroom activities. Lower impact activities had to do with comprehension of classroom materials (complex concepts).

I spend more time engaged in course activities in those courses that require me to use technology.

The instructors' use of technology in my classes has increased my interest in the subject matter. 3.25 Classes that use information technology are more likely to focus on real-world tasks and examples.

Interestingly, students do not feel that use of information technology in classes greatly increases the amount of time engaged with course activities (3.22 mean).12 This is in direct contrast to faculty perceptions reported in an earlier study, where 65 percent of faculty reported they perceived that students spend more time engaged with course materials

Only 12.7 percent said the most valuable benefit was improved learning; 3.7 percent perceived no benefit whatsoever. Note that students could only select one response, so more than 12.7 percent may have felt learning was improved, but it was not ranked highest. These findings compare favorably with a study done by Douglas Havelka at the University of Miami in Oxford, Ohio, who identified the top six benefits of the current implementation of IT as improving work efficiency, affecting the way people behave, improving communications, making life more convenient, saving time, and improving learning ability.14

Our data suggest that we are at best at the cusp of technologies being employed to improve learning.

The interactive features least used by faculty were the features that students indicated contributed the most to their learning.

he students in this study called our attention to performance by noting an uneven diffusion of innovation using this technology. This may be due, in part, to faculty or student skill. It may also be due to a lack of institutional recognition of innovation, especially as the successful use of course management systems affects or does not affect faculty tenure, promotion, and merit decisions

we found that many of the students most skilled in the use of technology had mixed feelings about technology in the classroom.

What we found was that many necessary skills had to be learned at the college or university and that the motivation for doing so was very much tied to the requirements of the curriculum. Similarly, the students in our survey had not gained the necessary skills to use technology in support of academic work outside the classroom. We found a significant need for further training in the use of information technology in support of learning and problem-solving skills.

Course management systems were used most by both faculty and students for communication of information and administrative activities and much less in support of learning.

In 1997, Michael Hooker proclaimed, "higher education is on the brink of a revolution." Hooker went on to note that two of the greatest challenges our institutions face are those of "harnessing the power of digital technology and responding to the information revolution."18 Hooker and many others, however, did not anticipate the likelihood that higher education's learning revolution would be a journey of a thousand miles rather than a discrete event. Indeed, a study of learning's last great revolution—the invention of moveable type—reveals, too, a revolution conducted over centuries leading to the emergence of a publishing industry, intellectual property rights law, the augmentation of customized lectures with textbooks, and so forth.

Both the ECAR study on faculty use of course management systems and this study of student experiences with information technology concluded that, while information technology is indeed making important inroads into classroom and learning activities, to date the effects are largely in the convenience of postsecondary teaching and learning and do not yet constitute a "learning revolution." This should not surprise us. The invention of moveable type enhanced, nearly immediately, access to published information and reduced the time needed to produce new publications. This invention did not itself change literacy levels, teaching styles, learning styles, or other key markers of a learning revolution. These changes, while catalyzed by the new technology, depended on slower social changes to institutions. I believe that is what we are witnessing in higher education today.

The institutions chosen represent a nonrepresentative mix of the different types of higher education institution in the United States, in terms of Carnegie class as well as location, source of funding, and levels of technology emphasis. Note, however, that we consider our findings to be instructive rather than conclusive of student experiences at different types of Carnegie institutions.

Qualitative data were collected by means of focus groups and individual interviews. We interviewed undergraduate students, administrators, and individuals identified as experts in the field of student technology use in the classroom. Student focus groups and interviews of administrators were conducted at six of the thirteen schools participating in the study.

We provide ample support and encouragement to "trailing edge" students whose online capabilities barely extend beyond e-mail, but at the same time, we leave the door open for those at the leading edge to suggest innovations that we ourselves would be incapable of imagining, much less of implementing.

By recasting students as researchers and teachers, we invite them to participate in what is arguably the most exciting and fulfilling aspect of university life: the production of new knowledge (Exhibit 2).

We would be hard pressed to name a profession—including academe itself—that does not demand some ability to interact effectively with other human beings. Yet higher education remains, especially in the humanities, a highly individualistic enterprise. In a typical English course, students write their essays for an audience of one—namely, the instructor who does the grading—while "group discussions" frequently consist of individuals talking directly to the teacher with little regard for their peers. In a discipline built around the ideal of the lone genius, our epigraph to this section remains as wishfully subversive today as it was a century and a half ago.

Teaching to the future involves harnessing the collaborative impulses already at large in digital culture and directing them toward educational ends, so that "group work" shifts in our students' perception from an eyeroll-inducing educational gimmick to a cutting-edge skill worthy of cultivation and scrutiny.

Later, they take part in a formative peer assessment exercise during which we project draft versions of their final projects onscreen while classmates ask questions and provide suggestions for improvement. The success of this "Live Crit" session (a concept borrowed from architecture and the fine arts) reflects the atmosphere of collaboration and trust that we have consciously cultivated among the students all semester

"In the coming decades," warns hypertext theorist Jerome McGann, "the entirety of our cultural inheritance will be transformed and re-edited in digital forms," a monumental task for which both we and our students remain, by and large, seriously underprepared (2005, 181).

to teach our students not to follow in our footsteps but to outstrip us.
