hat, exactly, constitutes a valid, original work? What are the implications for how we assess and reward creativity? Can a college or university tap the same sources of innovative talent and energy as Google or Flickr? What are the risks of permitting or opening up to this activity?

Remix is the reworking or adaptation of an existing work. The remix may be subtle, or it may completely redefine how the work comes across. It may add elements from other works, but generally efforts are focused on creating an alternate version of the original. A mashup, on the other hand, involves the combination of two or more works that may be very different from one another. In this article, I will apply these terms both to content remixes and mashups, which originated as a music form but now could describe the mixing of any number of digital media sources, and to data mashups, which combine the data and functionalities of two or more Web applications.

Harper's article "The Ecstasy of Influence," the novelist Jonathan Lethem imaginatively reviews the history of appropriation and recasts it as essential to the act of creation.3

Lethem's article is a must-read for anyone with an interest in the history of ideas, creativity, and intellectual property. It brilliantly synthesizes multiple disciplines and perspectives into a wonderfully readable and compelling argument. It is also, as the subtitle of his article acknowledges, "a plagiarism." Virtually every passage is a direct lift from another source, as the author explains in his "Key," which gives the source for every line he "stole, warped, and cobbled together." (He also revised "nearly every sentence" at least slightly.) Lethem's ideas noted in the paragraph above were appropriated from Siva Vaidhyanathan, Craig Baldwin, Richard Posner, and George L. Dillon.

Reading Walter Benjamin's highly influential 1936 essay "The Work of Art in the Age of Mechanical Reproduction,"4 it's clear that the profound effects of reproductive technology were obvious at that time. As Gould argued in 1964 (influenced by theorists such as Marshall McLuhan5), changes in how art is produced, distributed, and consumed in the electronic age have deep effects on the character of the art itself.

Yet the technology developments of the past century have clearly corresponded with a new attitude toward the "aura" associated with a work of invention and with more aggressive attitudes toward appropriation. It's no mere coincidence that the rise of modernist genres using collage techniques and more fragmented structures accompanied the emergence of photography and audio recording.

Educational technologists may wonder if "remix" or "content mashup" are just hipper-sounding versions of the learning objects vision that has absorbed so much energy from so many talented people—with mostly disappointing results.

The question is, why should a culture of remix take hold when the learning object economy never did?

when most learning object repositories were floundering, resource-sharing services such as del.icio.us and Flickr were enjoying phenomenal growth, with their user communities eagerly contributing heaps of useful metadata via simple folksonomy-oriented tagging systems.

the standards/practices relationship implicit in the learning objects model has been reversed. With only the noblest of intentions, proponents of learning objects (and I was one of them) went at the problem of promoting reuse by establishing an arduous and complex set of interoperability standards and then working to persuade others to adopt those standards. Educators were asked to take on complex and ill-defined tasks in exchange for an uncertain payoff. Not surprisingly, almost all of them passed.

Discoverable Resources

Educators might justifiably argue that their materials are more authoritative, reliable, and instructionally sound than those found on the wider Web, but those materials are effectively rendered invisible and inaccessible if they are locked inside course management systems.

It's a dirty but open secret that many courses in private environments use copyrighted third-party materials in a way that pushes the limits of fair use—third-party IP is a big reason why many courses cannot easily be made open.

The potential payoff for using open and discoverable resources, open and transparent licensing, and open and remixable formats is huge: more reuse means that more dynamic content is being produced more economically, even if the reuse happens only within an organization. And when remixing happens in a social context on the open web, people learn from each other's process.

Part of making a resource reusable involves making the right choices for file formats.

To facilitate the remixing of materials, educators may want to consider making the source files that were used to create a piece of multimedia available along with the finished result.

In addition to choosing the right file format and perhaps offering the original sources, another issue to consider when publishing content online is the critical question: "Is there an RSS feed available?" If so, conversion tools such as Feed2JS (http://www.feed2JS.org) allow for the republication of RSS-ified content in any HTML Web environment, including a course management system, simply by copying and pasting a few lines of JavaScript code. When an original source syndicated with RSS is updated, that update is automatically rendered anywhere it has been republished.

"An API provides an interface and a set of rules that make it much easier to extract data from a website. It's a bit like a record company releasing the vocals, guitars and drums as separate tracks, so you would not have to use digital processing to extract the parts you wanted."1

What's new about mashed-up application development? In a sense, the factors that have promoted this approach are the same ones that have changed so much else about Web culture in recent years. Essential hardware and software has gotten more powerful and for the most part cheaper, while access to high-speed connectivity and the enhanced quality of online applications like Google Docs have improved to the point that Tim O'Reilly and others can talk of "the emergent Internet operating system."15 The growth of user-centered technologies such as blogs have fostered a DIY ("do it yourself") culture that increasingly sees online interaction as something that can be personalized and adapted on the individual level. As described earlier, light syndication and service models such as RSS have made it easier and faster than ever to create simple integrations of diverse media types. David Berlind, executive editor of ZDNet, explains: "With mashups, fewer technical skills are needed to become a developer than ever. Not only that, the simplest ones can be done in 10 or 15 minutes. Before, you had to be a pretty decent code jockey with languages like C++ or Visual Basic to turn your creativity into innovation. With mashups, much the same way blogging systems put Web publishing into the hands of millions of ordinary non-technical people, the barrier to developing applications and turning creativity into innovation is so low that there's a vacuum into which an entire new class of developers will be sucked."16

The ability to "clone" other users' mashups is especially exciting: a newcomer does not need to spend time learning how to structure the data flows but can simply copy an existing framework that looks useful and then make minor modifications to customize the result.19

As with content remixing, open access to materials is not just a matter of some charitable impulse to share knowledge with the world; it is a core requirement for participating in some of the most exciting and innovative activity on the Web.

"My Maps" functionality

For those still wondering what the value proposition is for offering an open API, Google's development process offers a compelling example of the potential rewards.

Elsewhere, it is difficult to point to significant activity suggesting that the mashup ethos is taking hold in academia the way it is on the wider Web.

Yet for the most part, the notion of the data mashup and the required openness is not even a consideration in discussions of technology strategy in higher educational institutions. "Data integration" across campus systems is something that is handled by highly skilled professionals at highly skilled prices.

Revealing how a more adventurous and inclusive online development strategy might look on campus, Raymond Yee recently posted a comprehensive proposal for his university (UC Berkeley), in which he outlined a "technology platform" not unlike the one employed by Amazon.com (http://aws.amazon.com/)—resources and access that would be invaluable for the institution's programmers as well as for outside interests to build complementary services.

All too often, college and university administrators react to this type of innovation with suspicion and outright hostility rather than cooperation.

those of us in higher education who observe the successful practices in the wider Web world have an obligation to consider and discuss how we might apply these lessons in our own contexts. We might ask if the content we presently lock down could be made public with a license specifying reasonable terms for reuse. When choosing a content management system, we might consider how well it supports RSS syndication. In an excellent article in the March/April 2007 issue of EDUCAUSE Review, Joanne Berg, Lori Berquam, and Kathy Christoph listed a number of campus activities that could benefit from engaging social networking technologies.26

What might happen if we allow our campus innovators to integrate their practices in these areas in the same way that social networking application developers are already integrating theirs? What is the mission-critical data we cannot expose, and what can we expose with minimal risk? And if the notion of making data public seems too radical a step, can APIs be exposed to selected audiences, such as on-campus developers or consortia partners?

a tension between their passions and interests and the Academy’s curricular obligations. When woven into the fabric of the classroom, blogs allow the participants to articulate their feelings as a way of addressing these tensions. As well, blogs provide a space where the participants’ interests and passions can bubble forth for the enrichment of the group.

By blogging effectively within classroom settings, we can mentor learner forays into public spaces.

We wish to emphasise the importance of distinguishing between using blogs as holders of factory-model teaching practices, and taking advantage of their connectivity and transparency to deepen and liberate learning from the confines of stagnant, teacher-centric models. Ignoring the transformative capabilities of connectivity, some teachers using blogs merely reproduce offline practices online. Limiting classroom blogging to one-way transactions of information and directives from teacher to learners may add convenience and efficiency to the classroom, but does nothing for learning itself. Nor does assigning and directing wooden, forced, framed discussions online, which result in little more than mind-numbing ‘busy work’. We belittle and infantalise our students, further rewarding docility and disengagement if we over-direct posts by giving minute instructions as to their content, number and direction.

classroom blogging,

focusing on emerging pedagogy rather than tools

We will examine hyperlinked slow-blogging as reflective learning; multimedia, interactive blogging as action-based learning; and connected, transparent blogging as social learning.

Reflection-through-writing is a powerful aid to information retention, which is poor unless the lesson is repeated in a variety of contexts

The learner, in the act of writing down what s/he has learned, solidifies understanding and reveals areas of confusion.

Traditionally this kind of reflective narrative, found in journals and portfolios, has helped learners gain skill at meta-discourse and take responsibility for learning in liberal arts contexts. Teachers follow progress and detect comprehension gaps while coming to know learners’ styles, contexts and preferences. Learner-teacher interactions through reflective writing can deepen important bonds, an important indicator of effective learning (Raider Roth 2005).

different kinds of learning contexts including vocational by inviting learners to contextualise the learning in their own way within personal experience, thereby making the learning their own (

But if limited to the kinds of practices achieved offline, while efficient and convenient, and affording keyboarding practice, this use ignores new literacies of connectivity, collaboration, communication and multimedia expression. It also leaves out learners for whom written reflection is not always optimal or possible.

Although a blog organises itself, ordinarily and on first view, in reverse chronological order, the latest post being most prominent, tagging and hyperlinking allow for more associative, lateral ways of organising and connecting thoughts. Even the novice learner can transcend the limits of time and linearity in linking nascent ideas, discoveries and meta-discourse on the learning, replacing ‘…the essentially linear, fixed methods that had produced the triumphs of capitalism and industrialism with what are essentially poetic machines that capture and create the anarchic brilliance of human imagination’

Learners can link to practices other than written as they struggle to articulate and thus retain and apply what they have learned. For example, some learners will naturally link to audio rather than to text files of their reflections; others will link to images they have taken that are reflective of the learning process and outcomes.

thereby extending the reflective practice into synthesis and analysis and invention

If we know we are being read, that our explorations have value out in the world, we tend to take more care with our expression and our thinking as communiqués to the Other as well as to the self.

From learner posts, the teacher can point to models and questions, to moments of creative and critical success. Learning deepens, writing strengthens: these successes in turn pull the writer back to the blog again and again, to reflect and to improve thinking and expression skills.

That these messages to the self (and by extension, to the class and the world) are archived by date and category (or tag) allows them to take their place in an ongoing narrative of the learning.

Linking out connects us to more than ourselves. So, in this time of crumbling communities and the cult of the individual, our learners can, through active hyperlinking within a reflective learning practice, become more self-aware rather than more self-absorbed.

In selecting media, learners gain critical awareness of the grammar of image and sound as well as language. They learn to evaluate the impact of visual media on their discipline, on their society and on their lives as they develop skill at understanding structure, the arc of an argument, the use of transitions.

Hendrik and Ornberg have asserted, that ‘…audio is more effective than text for creating a sense of co-presence’

Students learn the discipline by doing the discipline

Evie’s work on the web, and in turn catapulted one of our learners into the role of activist and advocate for a cause about which she cared deeply.

By the end of the semester, Evie was not only a committed and involved activist for women’s rights, but a published photographer.

And so, the apprentice became the master, the student became the teacher, and Sean’s blog is fulfilling by becoming a valued resource for a teacher in Argentina and for her students as well.

Her blogging world and her real world became forever ‘intertwingled’ when she started leaving comments on the blogs of some of the graffiti artists she was following, and they, in turn, left comments on her blog. What followed was a flurry of comments, Instant Messaging (IM) conversations, Skype (r) chats and blogposts each taking Claire ever closer to the very people she has studied and admired and analysed…from afar. After the class ended (and after Claire graduated) Claire’s interest in graffiti continued.

But just as in the case of Sean, Claire went from being the observer to participant and now to a creator of graffiti, thanks in part to the connections made via social software tools.

it is not difficult to see how a tool such as a blog can keep learners immersed in course content in a way that traditional, teacher and textbook-centric teaching simply cannot.

A third, and perhaps most significant, role for classroom blogs to play, then, is in social learning, in the forming of close bonds within the learning community itself and with the outside world. Blogs afford learners a strong sense of belonging to a dynamic learning collaborative, following the apprenticeship model of learning, in which everyone is expert and apprentice to one another

The job of the teacher using social software is to create an understanding in and amongst the participants that they need to work together as a social entity, as a collaborative group, that is linked to and communicating among themselves as well as with the world.

Student bloggers learn by collaborating with one another through online group projects and through discussions, both formal and informal, that spring up on a central course blog, what we call the ‘Motherblog’, and by linking to one another within their own blogs, and creating feedback loops through the commenting function. Students also learn from one another through the blog archives, which grow year by year. Although we still teach in a departmentalised, semesterised system, the archiving subverts the notion of isolated learning segments by carrying the blog’s accumulated wisdom from group to group, informing the new learners’ experiences by adding context, models and inspiration

And unlike a discussion board that might be hosted on a course management tool such as Blackboard, these multimedia posts and comments are archived, hyperlinked and are open and available to all and not just the class.

Learners and teachers bring into the community discussion their own expertise, prior learning, cultural perspectives. They can converse here about what interests them about what they are studying. This kind of informal discussion weaves the threads of collective intelligence, and it helps learners to think beyond the strict confines of the syllabus, seeing connections to themselves and the world.

The class uses Flickr to collect and share images to be used in image-only essays and reflections, and in multimedia texts.

As Garrison and Anderson (2003) point out, ‘…a community of learners is an essential, core element of an educational experience when higher-order learning is the desired outcome’ (2003:22)

Using blogs as a complement to the face-to-face classroom environment not only provides more time on task for the learners, but if left open to world (as opposed to behind a firewall or a password or contained within the shell of a Learning Management System) these tools allow the real world - those crucial informal learning networks - into our classrooms…and the remarkable connections that happen as a result.

We can invite the outside world into the course intentionally, by asking experts in our field to participate in time-limited blog-based discussions with our learners. In these ‘blogging invitationals’ our learners can interact with professionals, joining the conversation of the real-world discipline in a meaningful way.

Other powerful connections with the world outside the classroom can occur through inter-classroom or inter-school blogging exchanges, or in service-learning initiatives, in which university learners, for example, mentor younger learners via connected blogging and feedback through comments, classroom to classroom, as writing buddies.

Together with the Center for International Understanding, North Carolina in the World is developing partnerships based on digital collaboration between schools in North Carolina and nations ranging from China to Mexico. Teachers and students in partnering schools are learning to use Web 2.0 tools like web-conferencing and wikis to connect kids across continents. Not only do these efforts help to build a general knowledge of other countries in our children, they are providing concrete opportunities to use technology in new ways.
