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.

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.
