We’ve seen an explosion in computer-mediated teaching and learning practices based on Web 2.0, in variety and scope too broad to summarize here. Think of the range from class blogs to Wikipedia writing exercises, profcasting to Twitter class announcements, mashups and academic library folksonomies and researchers’ social bookmarking subscriptions. CMSes react in the following ways: first, by simply not recapitulating these functions; second, by imitating them in delayed, limited fashions; third, by attempting them in a marginal way (example: Blackboard’s Scholar.com). CMSes are retrograde in a Web 2.0 teaching world.

CMSes shift from being merely retrograde to being actively regressive if we consider the broader, subtler changes in the digital teaching landscape. Web 2.0 has rapidly grown an enormous amount of content through what Yochai Benkler calls “peer-based commons production.” One effect of this has been to grow a large area for informal learning, which students (and staff) access without our benign interference.

Moreover, those curious about teaching with social media have easy access to a growing, accessible community of experienced staff by means of those very media. A meta-community of Web 2.0 academic practitioners is now too vast to catalogue. Academics in every discipline blog about their work. Wikis record their efforts and thoughts, as do podcasts. The reverse is true of the CMS, the very architecture of which forbids such peer-to-peer information sharing. For example, the Resource Center for Cyberculture Studies (RCCS) has for many years maintained a descriptive listing of courses about digital culture across the disciplines. During the 1990s that number grew with each semester. But after the explosive growth of CMSes that number dwindled. Not the number of classes taught, but the number of classes which could even be described. According to the RCCS’ founder, David Silver (University of San Francisco), this is due to the isolation of class content in CMS containers.

If we focus on the copyright issue, then the CMS makes for an apparently adequate shield. It also represents an uncritical acceptance of one school of copyright practice, as it enforces one form of fair use through software. However, it does not open up the question of copyright. Compare, for example, with the Creative Commons option increasingly available to content authors in platforms such as Flickr or WordPress. That experiential, teachable moment of selecting one’s copyright stance is eliminated by the CMS.

Another argument in favor of CMSes over Web 2.0 concerns the latter’s open nature.

Campuses should run CMSes to create shielded environments,

Yet does this argument seem familiar, somehow? It was made during the 1990s, once the first Web ballooned, and new forms of information anxiety appeared. Mentioning this historicity is not intended as a point of style, but to remind the audience that, since this is an old problem, we have been steadily evolving solutions. Indeed, ever since the 20th century we can point to practices – out in the open, wild Web! – which help users cope with informational chaos. These include social sifting, information literacy, using the wisdom of crowds, and others. Such strategies are widely discussed, easily accessed, and continually revised and honed. Most of these skills are not well suited to the walled garden environment, but can be discussed there, of course. Without undue risk of exposure.

Put another way, we can sum up the CMS alternative to Web 2.0’s established and evolving pedagogies as a sort of corporate model. This doesn’t refer to the fact that the leading CMS is a business product, produced by a fairly energetic marketplace player. No, the architecture of CMSes recapitulates several aspects of modern business. It enforces copyright compliance. It resembles an intranet, akin to those run by many enterprises. It protects users from external challenges, in true walled garden style. Indeed, at present, radio CMS is the Clear Channel of online learning.

The academic uses of realtime search follow the pre-Web pedagogy of seeking timely references to a classroom topic. Think of a professor bringing a newspaper to class, carrying a report about the very subject under discussion. How can this be utilized practically? Faculty members can pick a Web service (Google News, Facebook, Twitter) and search themselves, sharing results; or students can run such queries themselves.

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)

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.).

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

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.

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).

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.

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.

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.

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.

most of the technologies that currently permeate Africa aren't terrestrial. There are very few telephone lines, but mobile penetration is higher than any other region in the world.

Instead, internet connectivity is distributed nearly entirely by satellite.

The developers who are coming up with solutions in the continent, the ones who are writing software or hacking hardware, are creating for some of the harshest environments and use-cases in the world. If it works in Africa, it will work anywhere."

Perhaps this thought is what motivated Google to invest in O3B Networks earlier this month. O3B Networks is an ambitious attempt to bring three billion people in the developing world (mainly in parts of Asia and Africa) online by launching sixteen inexpensive, low-orbit satellites. The potential benefits for Google are obvious. This is three billion new internet users, who will more than likely use Google to search, and who will potentially click-through Adsense links and use other Google products. An indicator that Google may be anticipating as much is their move into Africa last year. They've since opened offices and hired people in both South Africa and Kenya with plans to eventually operate out of all sub-Saharan African countries.

At the end of 2007 there were over 280 million mobile phone subscribers in Africa, representing a penetration rate of 30.4% Africa has become the fastest growing mobile market in the world with mobile penetration in the region ranging from 30% to 100% from country to country. Fastest growing markets are in Nigeria, South Africa and Egypt

The Democratic Republic of Congo, population 60 million, has 10,000 fixed telephones but more than a million mobile phone subscribers. In Chad, the fifth-least developed country, mobile phone usage jumped from 10,000 to 200,000 in three years.
