Small Schools + Big Buildings = Better Learning?

September 6, 2007

On Tuesday the Conservative Party announced the results of a policy working group which has looked at education and other public services (entitled Restoring Pride in our Public Services). One of the proposals (no. 7) discusses the role of smaller schools and recommends investigating the use of ‘several small schools under one roof’, an idea that has been tried in a number of American States.

As luck would have it, I was at the Association of Learning Technologies’ annual conference (ALT-C 2007: beyond control) yesterday, and by the far the most interesting talk was the keynote given by Professor Dylan Wiliam, who made what must be one of the first public responses by a leading educationalist to these proposals.

Ning

August 16, 2007

Remember Marc Andreessen? Perhaps not. But he played his part in the history of the Internet. Way back in 1993 he built X Mosaic, the first widely used Web browser. He’s now involved in social networking – building the software that is, rather than the actual getting out and meeting people. Ning is his latest project and TechCrunch, a blog that devotes itself to news of deals in the computer world, reports that it has just secured major funding.

Ning is unlike the mainstream social networking services like Facebook and MySpace in that you can create your own networks, or what MIT’s Technology Review calls ‘mini-MySpaces’ or ‘social nicheworks’. Ning is one of the growing band of what TechCrunch describes as ‘white label’ social networking sites: ones in which Ning provides the networking infrastructure and then steps back, allowing the user to build, customise and brand their own network.

House of Lords 2.0

August 10, 2007

Today’s report on Personal Internet Security from the House of Lords Science and Technology committee makes a small reference to the issue of the ‘openness’ of Apple’s iPhone, which I discussed on this blog last month. The first section of chapter 4 looks at usability vs security and presents an argument, based on expert evidence given to the committee, that there is always a trade off between security and usability (flexibility).

The report argues that interoperability with lots of different third party hardware devices and software products has been the priority for leading operating systems like Windows until very recently. This is Microsoft’s view of the system as ‘complex eco-system’. The report then goes on to note, however, that, because of the increasing level of concern about security, there may be a move towards locking users in to the products and software of one company in order to improve and guarantee security.

This ties neatly in to Apple’s approach, which the report summarises as: “Microsoft might seek to maximise flexibility at the expense of possible insecurity, Apple would sometimes make [security] decisions on behalf of users even if that made it more difficult to download and run third party applications” (p.36). It then notes that Apple plan to make iPhone a closed platform on which it is not possible to execute any non-Apple applications. But, as far as I can make out from Apple’s press release, the iPhone will support third party Web 2.0 applications. Indeed, Apple argue in the release that this allows them to extend the capabilities of the phone, via third party solutions, without compromising the security.

However, I’m not convinced about this. If the House of Lords are investigating Internet-based security, I think it’s highly likely that these kinds of applications represent some of the security worries the committee is looking into.

XML gets X-rated

August 8, 2007

XML is one of those technologies that usually goes about its business quietly, with hardly anyone noticing (a bit like me, I like to think). It is widely used for the exchange of data between applications and systems and it also provides the foundation of XHTML, the latest version of the mark up language that underpins millions of webpages. Recently, though, things in the XML world have got a bit heated, to say the least, and are likely to get more so in the next month or two. A new technical report by Walter Ditch, published by the UK universities’ JISC, and which I was involved with publishing, sets out to explain why.

It’s all to do with the seemingly mundane subject of how a computer goes about saving a word processed document or spreadsheet file and, in particular, which ‘flavour’ (format) of XML it should use.

Fresh food déjà vu: salivating all over again

August 4, 2007

Another case of Web-related déjà vu this morning with news from the Guardian that Amazon are launching AmazonFresh, a trial service to deliver fresh food in the Seattle suburbs. Readers with a long memory may recall the froth, excitement and general salivation over the thought of the financial rewards to be had from Web-based, grocery shop-and-deliver schemes during the wild days of the dot-com boom. Names like WebVan, PDQuick and Streamline come to mind – all went bust, losing billions of dollars of investor’s money.

Indeed, my copy of Evan Schwartz’s Webonomics (1997), widely read at the time, lauds Peapod, one of the first online grocery services, based in Chicago. Schwartz’s later book, Digital Darwinism (1999) is more cautionary, warning of problems with the way in which the company bought their stock from supermarket shelves, rather than setting up agreements with wholesalers. To be fair to Peapod, they did manage to evolve and are now part of Dutch food retailing giant Royal Ahold (and recently delivered their 10 millionth order).

All this perhaps offers a warning from history. Delivering fresh kippers is not the same as delivering books. In the UK, online shopping delivery has been relatively successful, but only because the main supermarkets are running the services themselves (and so can benefit from their existing distribution infrastructure and general retailing experience). Peapod survives because of its close tie with an existing food retailer.

Although there is some evidence that Amazon may have done their homework (they are going to be working directly with wholesalers and farmers) it’s quite possible that they may have bitten off more than they can chew with this one. It may be coincidence, but the Guardian notes that the stock market took nearly a 2% bite out of Amazon shares on hearing the news.

Email, blogging and sacking

July 27, 2007

After a leisurely Friday lunch, possibly involving the local hostelry, there’s many an employee who might spend part of the afternoon emailing a few old friends, doing a bit of IM and perhaps spending some time in their favourite social networking site.

Beware.

Wired magazine reports that nearly ten percent of companies (of those surveyed at least) have fired an employee for violating corporate email, messaging and blogging policies. Almost a third of companies actually employ people to analyze the outgoing email. The survey was carried out by Forrester (on behalf of Proofpoint, an email security company) amongst large American corporates but, still, makes you think doesn’t it?

Web 2.0 and email

July 20, 2007

The speed at which Web 2.0 technologies and services are changing the way young people communicate continues to gather pace. I spent the beginning of the week at a conference of university website managers and Web development staff. One of the speakers, Alison Wildish, from Edge Hill University, had some fascinating stats about students’ communication habits gained from some surveys she had carried out at the university.

Of the first year students who started last autumn, 98% had already been active in the blogosphere and social networking media space (MySpace, Facebook etc.). They had a strong preference for Instant Messaging over the use of e-mail for basic communication. Indeed, Alison revealed that only 25% of these new students had made any use at all of the student email account provided for them by the university. Obviously, this has made life a little difficult for academics and support staff wishing to communicate with the students. I’d have thought they would be grateful.

Something for the weekend: Web 2.0 and the digital bubble

July 13, 2007

Two recent reports from consultants KPMG make interesting reading if you are planning a quiet weekend in a garden chair or hammock. The first, Enterprise 2.0: fad or future, by Gary Matuszak, covers the emerging use of Web 2.0 social software in corporate environments. It argues that such software can be used to help tackle what it refers to as key modern management challenges: “knowledge sharing and management, problem solving, innovation and collaboration”. The report gives a number of interesting corporate examples of the use of Web 2.0 in these different areas. For example it details the use IBM has made of a series of internal wikis for project collaboration and a chat-room process in which thousands of employees participate, simultaneously, in “innovation jams” to debate new ideas.

The report is generally pretty up beat, arguing that Web 2.0 services could “fuel a burst of productivity, as e-mail and the Internet have already done.”

This contrasts neatly with the other KPMG report, The Digital Bubble, which argues that we are in the midst of a revolution driven by the digitization of content. Although this presents unprecedented opportunities, the report warns, darkly, of the great potential for a “digital bubble” not unlike the dot-com boom and bust of the early 2000s. KPMG argue that in the kinds of environment that currently prevail for many Web-related businesses (rapid growth and change, over-heated valuations, unproven business models etc.) there is a tendency for management to focus on growth and increasing market share at the expense of ensuring that “the operational strengths required to support this growth are properly in place”.

One thing the report doesn’t mention is the role that the ‘Network Effect’ played in the original boom and bust. This is an Economics concept that describes the increase in value, to the existing users of an interactive service (e.g. a telephone network), as more and more people start to use it. This increase in value is often used in business model calculations and is one of the big ideas driving the Web at the moment. However, it is not without problems. Without getting into the ins and outs of it, it turns out that recent work by two academics might show that the original formula used to calculate the Network Effect may have been badly understood. If you’re interested in this, I discuss it more in the section on the ‘big ideas behind Web 2.0’ in my report on Web 2.0, which was published in February. The reason I think this is important is because we need to understand where we’ve gone wrong in the past, and if the Network Effect was part of it, then it has to factored in to future business models.

We have been warned!

3-D Web

July 4, 2007

A few weeks ago I mentioned the 3-D Web in a post about Second Life. Along these lines, an interesting press release arrived this morning from a company who are launching a three-dimensional visualisation for Web searching – a tool they call SpaceTime.

A quick look at their demonstration shows that after executing a Web search all the relevant webpages are displayed in a three dimensional visualisation – what they call a 3-D stack – stretching away from the viewer. Clicking on a page brings it to the fore. This could be particularly useful for searching for an image as you can ‘thumb’ through the stack looking for the best one and the company says the product will work with Google Images and Yahoo images.

I’ve not had time for a detailed play but what’s interesting is that this way of moving around a connected series of visual images reminds me of a demo I saw a couple of years ago of Ted Nelson’s ZigZag data structures project. The data appeared in a series of connected stacks and you could mine information by spinning around a kind of three-dimensional ‘wheel’ of connected data.

As the amount of information we have to handle at any one time increases, the use of the 3rd dimension is going to become more prevalent.

Apple seeds of discontent

July 3, 2007

How extendable is the new Apple iPhone? By this I mean open to modification and the addition of software packages. The iPhone comes with an email client, calculator, calendar, and can read (not write) Word documents and PDFs, but what about other sorts of apps that you can run on your desktop PC or Mac?

Well, er, it’s not good news, I’m afraid. The iPhone platform does not allow the addition of new applications. In fact, it’s even more closed than a normal computer. Much to the chagrin of software developers Apple is not allowing third parties to port (adapt) their applications to the phone.
