Preoccupations

Back in May …

… St Paul’s held an open day to celebrate its 500th anniversary. For our part, we put together a small show in our main ICT room. My thanks to the four pupils who helped me set this up and who looked after our visitors so well for the whole of what was a fun but long afternoon.

     

Making use of the bank of desktop machines in the room, we gathered together a number of videos under this umbrella:

A brief introduction to the modern web: an overview of how computers shrank, became mobile and ever more powerful, an insight into how we teach about all this and a glimpse of the world we’re all soon going to be living in.

It may be that some of what follows in this longish post (a lot of video) is of interest beyond the immediate occasion of the day. I put the videos in playable form here as you may want to scan quickly and then dip in when something catches your eye. On the day, visitors could go round a number of videos/slideshows (mostly paired and in the sequence below) but of course, and as we expected, people dipped in and out: it was that or giving over a lot of the afternoon to this one room. (For me, in these very general talks or events, there’s quite a bit of churn, but it seems always to be the case that there’s plenty of new hooks for anyone whose life isn’t spent immersed in this stuff.)

Incidentally, one of the successes of the afternoon was the discovery of what you can do with the simplest of devices. Spotted in the field the previous week at Manchester’s Urbis, Staples’ slanted clear acrylic sign holders are a brilliant way of signing an exhibition with the minimum of fuss and a lot of clarity:

  

The only nod towards a more formal, display-board style of presentation was this:

Finally, alternating on the overhead projector throughout the afternoon were these videos:

                     

1/

Slideshow 1 (credits as per the links and also: original Apple iPhone ads — see 6/ below; stills from Did You Know; the Flickr slide — from here).

A short history of how computers have grown in power, how their size has got smaller and smaller … and how they’ve gone mobile. Also (and very swiftly), an overview of developments in technology and the web, the advent of both cloud-computing and ubiquitous computing … and the emergence of astonishingly rich social sites and practices.

 
Steve Jobs (1991?) talks about what computers mean to him: ‘Computers are like a bicycle for our minds’.

 

2/  Apple, 1984

In January 1984, a youthful Steve Jobs demonstrated the first Apple Mac. This film still has the power to impress, such was the reception this innovative machine received. And then there’s also Jobs’ own reaction …

This advert, directed by Ridley Scott, was shown on US TV in 1984 and introduced the Mac personal computer. As they said in a later campaign, Think Different.

 

3/  California dreaming

‘Knowledge Navigator’: another Apple film, from 1987, imagining a personal computer that would be like a PA, memex machine, scholastic aid, visual display — oh, and phone. (Sound familiar?)

‘Time Capsule’: an Apple film made in 1987 and imagining the future of 1997. “No question about it, the 1990s have really been the Apple decade.”

 

4/ Google and Cloud-Computing

It’s hard to believe that Google is just ten years old. In January this year, the company released this film looking back at what they’d done in that time. All 4^th Formers get a thorough grounding in using Google’s tools and in managing their personal identity and privacy.

Cloud-computing: more and more of the data we create and use and store is not on our devices but “in the cloud” — in data centres such as this one. Google makes energy efficiency a priority.

 

5/  Google Earth

Everyone knows Google Earth and Google Street View. We explore in our 4^th Form course the implications of these technologies for the visualisation of information. We also discuss the emergence of location-based social software and its implications for privacy.

Here’s a beautiful example of the educational value of Google Earth: Ancient Rome (a layer in Google Earth) as it looked in 320AD.

 

6/  iPhone

A game-changing device. The original advertising campaign from June 2007 summarises brilliantly what had been achieved.

The iPhone brought touchscreens into the lives of many. Will it be a key player in bringing ubiquitous computing into our lives, too? 4^th Formers are taught that “computers” are much more, and much more present in our lives, than the single desktop this film is playing on.

 

7/  Living in a digital world

Slideshow 2:

An idea of how our students use web-based tools and a panoramic view of our course for 4^th Formers.

(I used much of this material in my talk at C4’s recent What Comes Next? The Channel 4 Education Summer Conference.)

Editing Wikipedia: a time-lapse film of the edits made to the page about the London 7 July, 2005, bombings. The article was created, that morning, at 9.15am. In its first four hours, it was edited over a thousand times. All 4^th Formers are taught how to understand, evaluate, use and edit Wikipedia.

 

8/  The near future

CGI: no water was harmed in this film. Or even used. Programmers from St Paul’s can look forward to working on enhancing such techniques even further, in film and videogames.

Big Dog, a robot built by Boston Dynamics, walks on rough terrain and ice whilst carrying heavy loads (340lbs). Control Technology works in areas that prepare students for fields like this.

                                          

 

9/  Games

A contentious area for some, the development of a substantial body of critical literature and the wise words of respected reports such as last year’s Byron Review, along with research and better knowledge generally, are leading to a more considered reception of computer games. This slideshow outlines some important research from last year and highlights a talk given here in November 2008.

Old Paulines created Rockstar Games (Grand Theft Auto, etc). In school today, we are creating an intelligent ethos for the discussion and understanding of games.

In designing videogames, something called The Uncanny Valley needs to be avoided. An entertainingly presented talk.

 

10/  The internet of things

Many of us have grown up thinking the internet is mainly the web — a web of pages. But the machines are coming: embedded devices of all kinds … Machines … talking … to us.

Gartner think that, “By year end 2012, physical sensors will create 20 percent of non-video internet traffic. … The extent and diversity of real-time environmental sensing is growing rapidly as our ability to act on and interpret the growing volumes of data to capture valuable information increases.”

Sensors to monitor energy consumption will become very common. Simon Hay, OP, has been working on this concept (see this poster and site) and three current pupils in the school will be using AMEE to record and monitor our energy usage.

This final Apple video shows the iPhone 3.0 and its use with medical devices — for example, in the monitoring of diabetes.

 

(And for further food for thought, Matt Jones’ iPhone 3.0: everyware-ready?.)

 

11/  Getting it wrong

So many of the things we imagine about the future are wildly wrong. This trip round the recent past and the fast-developing present has tried to avoid such wild predictions, preferring to look instead at some things that are coming true already (a near-future becoming the present) or that are already here.

Cue Postcards Show the Year 2000 (circa 1900). And then:

Here, in two parts, is the GM Futurama 1939 World’s Fair looking ahead to the imagined 1960s, a techno-utopian vision we still haven’t achieved.

Being that much better

From the immemorial to the ephemeral. I’ve been moving steadily Mac-wards in the last couple of months. If nothing else, it’s liberating to learn to think with different tools. (The desire to have tools that are ready-to-hand, but the value that lies in appreciating constraints — then we have a fighting chance when the picture might otherwise hold us captive.)

The operating system I should really be using is Linux, for the reasons John Gruber summed up so well in a footnote to his recent blog post about Google Chrome OS/vapourware. What he had to say about Linux is so good it’s worth quoting it all:

“Linux” means different things to different people. At a precise technical level, Linux is not an operating system. It is a kernel that can serve as the core for an operating system. What most people mean by “Linux”, though, is an operating system built around the Linux kernel. For use as a desktop PC operating system, all the various “Linux distributions” are basically the same thing: variations of Gnome or KDE sitting atop the ancient X Window System.

Ubuntu is almost certainly the pinnacle of these distributions, but they’re all conceptually the same thing, and the only significant difference is the choice between Gnome and KDE, and even there you’re just choosing between two different environments that are conceptually modeled after Microsoft Windows. The entire X Windows/Gnome/KDE “desktop Linux” racket has never caught any traction with real people. Almost no one wanted it, wants it, or will want it.

My theory on this is rather simple. Early versions of Gnome and KDE were pretty much just clones of the Microsoft Windows UI. They’ve diverged since then, and I’d say Ubuntu’s default Gnome desktop is in most ways better from a design and usability standpoint than Windows Vista. But it’s still fundamentally a clone of Windows — menu bars within the window, minimize/maximize/close buttons at the top right of the window, the ugly single-character underlines in menu and button names. At a glance it looks like Windows with a different theme. The idea being that if you want Windows users to switch to Gnome or KDE, you’ve got to make it feel familiar. But that’s not how you get people to switch to a new product. People won’t switch to something that’s just a little bit better than what they’re used to. People switch when they see something that is way better, holy shit better, wow, this is like ten times better.²

So I think Gnome and KDE are stuck with a problem similar to the uncanny valley. By establishing a conceptual framework that mimicks Windows, they can never really be that much different than Windows, and if they’re not that much different, they can never be that much better. If you want to make something a lot better, you’ve got to make something a lot different. …

² The group that’s the most enthusiastic about Gnome and KDE desktop Linux systems consists of those who care the most about the political and licensing aspects. With regard to the freedoms that stem from the software being open source, something like Ubuntu isn’t just, say, ten times better than Windows or Mac OS X, it is infinitely better.

In amidst fruit-picking, I’m playing with a better camera and I think I’m moving on a little, inspired by time spent alongside Jonathan, engaged by how he works, and, interesting-to-me, by computer games. To start with, that familiar sense of panic that, years ago, poetry once gave me (“I’ll never get this”) and then, at first slowly then more and more quickly, the coming of understanding and pleasure. Games absolutely encourage a try-and-fail-and-try-again approach. I used to be paralysed by the seeming unpredictability in learning anything much at all about digital photography, but treating it like play (which is certainly how I see Jonathan set about things) makes it all right — and fun.

Tools for thought: this post was semi-made on a Mac — I could have made this in a pure-Mac way (following a path no doubt excellent but seemingly laborious), but LiveWriter remains the best tool I know for blogging (a lot of the time it gets out of the way). And VirtualBox is free — and works.

Things (and quite a few people) are talking to me

One of the bits of our new course for Year 9 that has given me the most pleasure to write is the part about microblogging. We have a number of students nurturing entrepreneurial ambitions and, when their ideas hit some kind of maturity, the next thing they may come to talk about is how to get themselves known. Looking at how Stephen Fry has used Twitter to reach a lot of people is something instructive to put before these students (if only because of what makes him so different), but everyone can benefit from looking at this sequence below. There’s much food for thought here — about celebrity and the web, brands and the web, scale, writing for unknown audiences, creating and sustaining (and providing confirmation of) your digital identity, the relationship between the person posting and the companies she/he is associated with … as well as “just” microblogging in general, of course. (Roo has a very good post, How do you use Twitter?, that I recommend to our students.)

 

 

That’s one strand.

Then, all those things now a-twittering: Andy House, Botanicalls0106, Mars Phoenix, the Shipping Forecast, Tower Bridge … old Father Thames.

Oh to be young now and see how this all works out. Matt: "treating the web not as a web of pages and websites but as a web of data"; "digital and physical things—and, increasingly, excitingly—things that can’t make up their mind which they are". Russell: "The stuff that digital technologies have catalysed online and on screens is starting to migrate into the real world of objects."

In just one lesson (35 minutes) a week, in just one year group, sometimes we can’t do more than give a heads-up (omitting so much), but I hope our nascent engineers, software developers, designers, advertisers, planners of cities, architects, climate scientists, privacy activists, politicians, doctors, civil servants … in short, all wide awake citizens-to-be are getting this.

 

 

PS   I haven’t even mentioned Google Profiles — have you created yours (or taken the decision not to)? Or used that new Contact info tab yet? There’s a bit about them, and Windows Live Profiles, in Lesson 17. Jyri just twittered, “Google profiles reached that state where it was time to point my blog’s About link there”.

Our work (so far) this year

It’s again been an exhilarating experience to teach our first year’s (13 year-olds) their ICT course. The pace of adoption by them of technological developments still surprises: once again, I notice how this year’s cohort is just that much further on than the equivalent year group last year. It’s not just us, the adults, who notice this: where we might think that teenagers swim in all this digital stuff like fish in water, it’s eye-opening to watch only slightly older students being amazed at what 13 year-olds now know. So last month, a year on from when I last posted here about this course, I was feeding back to colleagues whose specialism is not ICT:

Last year, for example, we taught about tabbed browsing, but this year we didn’t need to: our 13 year-olds are experimenting freely with different browsers, wasting no time in downloading and adopting the recently released Google Chrome. They joined the school knowing more than last year’s 4ths about operating systems and several have experience of Linux. They are keen to learn about how they can maintain their personalised experience of computing (by exploiting web apps) when using the school’s networked machines and many were already using iGoogle before joining St Paul’s. One 4th former routinely uses PortableApps and showed others how to do the same. Others know about running Firefox from a memory stick, retaining all their individual settings no matter what PC they are on. There is a wide range of hardware in use and the barrier between desktop machines (hitherto commonly taken to be synonymous with computers) and mobile devices has gone — notebooks, mini-books, smartphones, the iPodTouch, iPhones ... all proving their computing worth in day-to-day life. Location-based services are being widely used on mobile phones; such services are coming soon to browsers (Firefox, Chrome) and operating systems (eg, Windows 7).

Some further context here: a year ago, iGoogle was alien to nearly all our first years; memory sticks were used more or less only as … memory sticks — running apps off of them was a fringe experience; browsers and the exploitable differences between them simply hadn’t the popular prominence they have now. Most interesting in many ways to me is the demand for Open Source software: because of 13 year-old, pupil-led demand we are networking Open Office, running it alongside MS Office. It’s up to the user which product he/she wants to use. I’m also interested in reports from colleagues about 13 and 14 year-old pupils, when asked to create a document or to collaborate, opening web-based apps as a matter of course.

So, the course as it is evolving this year is currently online here. I have no doubt, though, that we are now at a watershed and, as I also summed things up for colleagues, ‘The current course, revised from that of last year, will need fundamental revision for next year in order to keep pace with the changes afoot and the rate of adoption by young teenagers’. In particular, I think we’re now ready to make a fundamental shift towards the creative — and this pleases me a great deal.

They don’t have blogs, or I’d link to them, but my gratitude to the team with whom I co-teach this course (Richard, Andrew, Olly, David) is great: my thanks to them for all their hard work and enthusiasm.

This year has been very busy on a number of other fronts. We took the decision late last academic year to re-design our website and asked Clearleft to undertake the work. As I knew it would prove, it’s been a pleasure to work with Clearleft: we’re somewhere around halfway through the project and I’ve learned a great deal from them — about web-design, for sure (we had fun with affinity diagrams and played with post-its), but also about how good design work probes and challenges a company’s perception of how it’s promoting itself. I recommend the experience.

We’ve also been working a lot with Firefly, the company who write the software that powers both our website and our intranet. Simon and Joe, the founders and developers of Firefly, were pupils at St Paul’s and wrote the first iteration of Firefly whilst studying here. With the great help of Jess and Serena from Headshift, we have worked together, discussing how the interface and capabilities of Firefly might be developed, and this month saw the release of the new product. Thank you, Joe and Simon, for all your work on this. In summary: comments can now be enabled on all pages; we have blogs; the editing interface has been re-worked and made in-line, write-access is on by default and key editing options are immediately visible in hover-over mode; RSS has been made both much more obvious and widely available; the permissions dialogue has been improved and made more transparent; search has been improved both in UI and performance; template documentation is on its way, as is tagging; shared workspaces are available; calendaring now supports iCal; pages are owned by their creators but stewardship of a page is assignable (useful with classes, projects, etc). These are major software improvements for our intranet (which has amassed some 25,000 pages), providing us with something to build on collaboratively (staff and pupils) and develop further.

When we were deliberating the next iteration of our ICT Development Plan, I wanted green computing to be high on the agenda and I’m delighted that we worked with Gavin at AMEE and are now poised to start aggregating our energy data for the school (ie, the whole site) with AMEE. Our building program recognised the importance of sustainability from the outset.

We’ve been in discussion with Google about starting a branded YouTube channel. We filmed most of this year’s talks (see below) and have these and other stuff to go up. All this takes time, of course, but it’s coming.

This year we also began what I sense is necessarily a thoughtful, slow and sensitive engagement with games and gaming. These have a poor standing in schools, yet their cultural influence and their ubiquity in the lives of many younger people (by no means “just” students) is evident and widely reported. Grand Theft Auto originates from Paulines, of course, and it was high time to address the whole “matter”. We founded a society this term, met a couple of times (the first time without anyone, perhaps, realising it was meeting) and grew it out of two influential, important talks (see below). Next term we move the throttle forward and give it some more oomph. Those involved (it’s pretty popular) bought the idea of everyone reading more about games, and we’ll start with Steven Johnson’s Everything Bad is Good for You.

We’ve had a great run of speakers so far this year, with more to come. Last academic year I blogged these talks as we went, but this year things have been too busy for that (along with all the work detailed here, I’ve also switched to commuting daily, which involved decamping mid-term from my school flat and giving some much overdue attention to our own home — and then there was learning to live with First Great Western …). So here’s the run-down …

Kayaking

The internet means you don’t have to convince anyone else that something is a good idea before trying it.
— Scott Bradner, former trustee of the Internet Society (quoted in Here Comes Everybody)

The communications tools broadly adopted in the last decade are the first to fit human social networks well,
and because they are easily modifiable they can be made to fit better over time. — Clay Shirky (Here Comes Everybody, p 158) 

Back before Easter, I was at the ICA for the Eno/Shirky evening. One of the books I then read over the break was Here Comes Everybody. I’ve been meaning for some time to put down a few notes about it here. This has grown to be a long post as I’ve added to it, wanting to get a few things out on the page and, so, clearer in my own mind.

It’s a great book to suggest to friends who are not familiar with the technologies Shirky discusses as it hides its knowledge well — but there are still leads to follow up. The modest ten or so pages of the Bibliography threw up a number of articles I'd either not heard of before or hadn’t visited in a long while. In the former camp, I recommend: Anderson: More Is Different (Science — 1972); R H Coase: The Nature of the Firm (pdf) — a 1937 economics paper; Richard P. Gabriel — Lisp: Good News, Bad News, How to Win Big: worse is better (1991); Alan Page Fiske: Human Sociality. (There’s an online “webliography” here.) And chapters 8–11, covering so many big topics — social capital; three kinds of loss (some solve-a-hard-problem jobs; some social bargains; negative aspects to new freedoms); small world networks; more on social capital; failure (‘open source … is outfailing’ commercial efforts, 245); more on groups (‘every working system is a mix of social and technological factors’, 260) — hit my Amazon Prime account hard. (Incidentally, there’s a Kevin Kelly piece on “more is different”, Zillionics, that appeared earlier this year. See also Kevin Kelly’s The Google Way of Science and Wired’s The Petabyte Age: Because More Isn't Just More — More Is Different.)

Further reading to one side, a number of things discussed in the book particularly interested me straightaway. Firstly, sociality, privacy and exposure online. Leisa recently posted Ambient Exposure, an update (of sorts) to her post of last March, Ambient Intimacy. The titles tell their own story. Early on, Clay writes about ‘how dramatically connected we've become to one another … [how much] information we give off about our selves’. This took me back to Adam Greenfield’s recent talk at the Royal Society (I’ve also been re-reading Everyware). Our love of flocking is being fed handsomely by means of the new tools Clay Shirky discusses so well.

Privacy is always coming up in conversations at school about online life, and what I’m hearing suggests our students are beginning to look at privacy and exposure with growing circumspection. Facebook’s People You May Know functionality has made some sit up and wonder where social software might be taking us. We’re slowly acquiring a stronger sense of how seduction through imagined privacy works (alone in a room, save for screen and keyboard) and a more developed understanding of what it means to write for unseen audiences. Meanwhile, there are things to be unlearned: ‘those of us who grew up with a strong separation between communication and broadcast media … assume that if something is out where we can find it, it must have been written for us. … Now that the cost of posting things in a global medium has collapsed, much of what gets posted on any given day is in public but not for the public’ (90).  In the Bibliography, Clay refers to a post of Danny O’Brien’s — all about register — which is a longtime favourite of mine, too.

Then there was what the book had to say about media and journalism. Simon Waldman, well-placed to pass comment, on chapters 3 and 4:

The chapters most relevant to media/journalism - ‘Everyone is a media outlet’ and ‘Publish first, filter later’ should be required reading for pretty much everyone currently sitting in a newspaper/broadcaster. It’s certainly the best thought through thing I’ve read on this, and the comparison to the decline of the scribes when the printing press came in is really well drawn. 

The summary to Chapter 4 (‘Publish, Then Filter’) runs, ‘The media landscape is transformed, because personal communication and publishing, previously separate functions, now shade into one another. One result is to break the older pattern of professional filtering of the good from the mediocre before publication; now such filtering is increasingly social, and happens after the fact’. ‘Filter-then-publish … rested on a scarcity of media that is a thing of the past. The expansion of social media means the only working system is publish-then-filter’ (98). (Language like this can sound an utopian note that rings on in the head long after the book’s been closed, as if we’d entered a world beyond old constraints. And look!: the Praetorian Guard of elite gatekeepers is no more.)

I was interested, too, to read Shirky’s thoughts about the impact of new technologies on institutions. His application of Ronald Coase’s 1937 paper and, in particular, the idea of the Coasean floor (‘activities … [that] are valuable to someone but too expensive to be taken on in any institutional way’), was very striking: the new tools allow ‘serious, complex work [to be] taken on without institutional direction’ and things can now be achieved by ‘loosely coordinated groups’ which previously ‘lay under the Coasean floor’.

We didn't notice how many things were under that floor because, prior to the current era, the alternative to institutional action was usually no action. (47)

Later in the book (107), he comes back to institutions, taking what is happening to media businesses as not unique but prophetic — for ‘All businesses are media businesses … [as] all businesses rely on the managing of information for two audiences — employees and the world’:

The increase in the power of both individuals and groups, outside traditional organisational structures, is unprecedented. Many institutions we rely on today will not survive this change without significant alteration, and the more an institution or industry relies on information as its core product, the greater and more complete the change will be. The linking of symmetrical participation and amateur production makes this period of change remarkable. Symmetrical participation means that once people have the capacity to receive information, they have the capability to send it as well. Owning a television does not give you the ability to make TV shows, but owning a computer means that you can create as well as receive many kinds of content, from the written word through sound and images. Amateur production, the result of all this new capability, means that the category of "consumer" is now a temporary behaviour rather than a permanent identity.

‘Every new user is a potential creator and consumer’ (106) is reminiscent of Bradley Horowitz in Creators, Synthesizers, and Consumers (2006).

Mobiles

To get a sense of how rapidly cellphones are penetrating the global marketplace, you need only to look at the sales figures. According to statistics from the market database Wireless Intelligence, it took about 20 years for the first billion mobile phones to sell worldwide. The second billion sold in four years, and the third billion sold in two. Eighty percent of the world’s population now lives within range of a cellular network, which is double the level in 2000. And figures from the International Telecommunications Union show that by the end of 2006, 68 percent of the world’s mobile subscriptions were in developing countries.

— from The New York Times article focusing on the work of Jan Chipchase (and colleagues), Can the Cellphone Help End Global Poverty?.

… have you ever stopped to wonder why? Why, regardless of culture, age, gender and increasingly context you're likely to find a mobile phone in the hand, pocket or bag of the person next to you? Put simply - the ability to communicate over distances in a personal convenient manner is universally understood and appreciated, and it's easy enough to get the basics without going to night school or taking a PhD. It certainly helps that, as a functional tool that can be used discreetly or with a flourish, the mobile phone makes an ideal vehicle for projecting one’s status and personal preferences - from the choice of brand, model, ring tone or wallpaper, or simply that (because you're connected) you've arrived.

Today over 3 billion of the world's 6.6 billion people have cellular connectivity and it is expected that another billion will be connected by 2010. But what is often overlooked is the disproportionate impact of mobile phones on different societies, which is one of the reasons why as researchers, we increasingly prefer to spend time in places like Cairo and Kampala: there is simply more to learn. These are places where for many, it's the first time they have the ability to communicate personally and conveniently over distances - without having to worry whether someone can overhear the topic of their conversation - communicate with whom they want, when they want. It makes new businesses viable and creates markets where there was none. For many it's the first time they can provide a stable fixed point of reference to the outside world - a phone number, which in turn creates a new form of identity that in turn enables everything from rudimentary banking to commerce. And not least - each new feature on or accessible through the mobile phone brings new modes of use - unencumbered by my, and probably your entrenched (and increasingly outdated) notions of entertainment, the 'right' way to capture and share experiences, the internet. If you work or study in the mobile space and you're expected to innovate, these are places that bring fresh thinking and new perspectives.

— from Jan Chipchase's article, Small Objects, Travelling Further, Faster.

The human race is crossing a line. There is now one cellphone for every two humans on Earth. ... we've passed a watershed of more than 3.3 billion active cellphones on a planet of some 6.6 billion humans in about 26 years. This is the fastest global diffusion of any technology in human history -- faster even than the polio vaccine.

"We knew this was going to happen a few years ago. And we know how it will end," says Eric Schmidt, chairman of the board and chief executive officer of Google. "It will end with 5 billion out of the 6" with cellphones. ... "Eventually there will be more cellphone users than people who read and write. I think if you get that right, then everything else becomes obvious."

"It's the technology most adapted to the essence of the human species -- sociability," says Arthur Molella, director of the Smithsonian's Lemelson Center for the Study of Invention and Innovation. "It's the ultimate tool to find each other. It's wonderful technology for being human."

Ted Nelson @ St Paul's II

The Bush years have not been kind to those Americans living abroad and dependent on the dollar exchange rate. Out of necessity, then, Ted and Marlene, who first came to St Paul's in July 2007 (see here), are soon to return to the States — but, before leaving, they revisited St Paul's. Today, Ted spoke about his work, his current book-in-progress (Geeks Bearing Gifts) and Xanadu.

Farhan's blogged Ted's talk so well that there's little left for me to add. Thanks!

There were some lovely glimpses into Ted's childhood — a boy who loved reading and words and knew, by ten, who had coined tintinnabulate … chortle … serendipity; growing up in Greenwich Village without realising it, then reading about it and longing to see this Bohemian paradise; experiencing Mrs Roosevelt as a near neighbour. He was (as expected) both amusing and savage about the blackhole which is the clipboard. His father had taught him that writing is mostly re-writing, and re-writing is mostly rearrangement — so why devise writing tools that are so bad they hide the very material you're cutting? (CTRL+C, CTRL+V: cram and vomit.) By the time he went to college, he'd written a lot by linking cut and pasted pieces of writing.

Graduate school in 1960 and a computing course saw him suddenly quite sure that personal computers would come and that his job was to design the documents of the future: make it possible to see the parts and compare the versions, to visualise the origins of quotations, to expose deep rearrangements. Hypertext was first used by Ted in 1963, but it was 1986 before it was used outside his immediate circle.

It was great to have Ted and Marlene here again. I was particularly pleased that a number of our 13/14 year-old students came along: Ted has been a name to them in their ICT course — and here he was.

Wi-Fi and health

Recently, I needed to prepare something for use at school that would act as a summary to date of this debate. I took as my markers some of the high profile coverage Wi-Fi has received over the last year. It might be worth publishing this brief overview here.

1)  There's no basis for proceeding that's worthy of our consideration other than one based on the scientific evidence. There's masses of conjecture which generates fear, uncertainty and doubt.

2)  Let's start with mobile phones and phone masts - forms of wireless communication the radiation from which is (at source) far more powerful than that emitted by the kinds of wireless access points we'd be installing.

a)  December, 2006: Journal of the National Cancer Institute, a study of 420,095 cell phone users (Danes). They began subscribing to cellular phone services between 1982 and 1995, and the study examines their cancer rates through to 2002. The study 'finds no increased risk of tumors or leukemia in subscribers'; 'Even among the 56,000 people who have used the phones for more than a decade, researchers found no increased risk of cancer'.

b)  July, 2007: the Essex University phone mast study — 'when tests were carried out under double-blind conditions, where neither experimenter nor participant knew whether the signal was on or off, the number of symptoms reported was not related to whether the mast was on or off. Two of the 44 sensitive individuals correctly judged whether the mast was on or off in all six tests, compared with five out of 114 control participants. This proportion is what is expected by chance and was not increased in the sensitive group'.

3)  Now we come to the Panorama programme, 'Wi-Fi: A Warning Signal', that ran last May and which the BBC's editorial complaints unit subsequently (November) conceded had not had 'adequate balance' and so had given 'a misleading impression of the state of scientific opinion on the issue'.

a)  There's a a succinct and clear explanation of a fundamental flaw in the Panorama programme here. From the same source: 'Wi-Fi uses radio frequency (RF) waves that are "non-ionising" - that means they are not powerful enough to knock electrons off molecules in cells. One way they could harm cells is by heating them up. But this requires much higher power than is delivered by Wi-Fi networks or mobile phones (which use similar frequencies).  As every cautious scientist will tell you, you can never prove that something is absolutely safe and no one would want to gamble with the health of children. But there is good reason for thinking that Wi-Fi is, if anything, safer than the radiation from a mobile phone. The UK's Health Protection Agency says a person sitting within a Wi-Fi hotspot for a year receives the same dose of radio waves as a person using a mobile phone for 20 minutes'.

b)  Ben Goldacre, who, of course, writes the excellent Guardian 'Bad Science' column, took the Panorama programme to pieces and has also analysed the whole melange of ideas swirling round the "electrosensitivity" theme: Electrosensitives: the new cash cow of the woo industry; Wi-Fi Wants To Kill Your Children… But Alasdair Philips of Powerwatch sells the cure! ('Of course you should be vigilant about health risks. I don't question that there may be some issues worth sober investigation around Wi-Fi safety. But this documentary was the lowest, most misleading scaremongering I have seen in a very long time.')

4)  I felt it was probably worth my including the two Independent articles from last year, Danger on the airwaves: Is the Wi-Fi revolution a health time bomb? and Wi-Fi: Children at risk from 'electronic smog' (both from April). These will have lodged themselves in the minds of some — and they're truly bad. Ian Betteridge took both apart here, concluding, 'what really matters is that the quality of the Indie's reporting on this is abysmal. Printing scare stories isn't just bad journalism - it's bad behaviour that actually damages our culture, promoting bad, hokey ideas as fact and encouraging anti-scientific and anti-rational propaganda. I'd love to ask the editor of the Indie which they prefer - a world where science and reason are encouraged, or a world of cranks, quacks and charlatans'.

A paragraph or two summing up what we can say we know and how best, then, we should proceed?  I can't really do better than these, from the Guardian article already cited in 3a above:

The World Health Organisation's advice on this is very clear. "Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF signals from base stations and wireless networks cause adverse health effects."  And an HPA statement issued last week is equally adamant that Wi-Fi almost certainly does not pose a problem. "On the basis of current scientific information Wi-Fi equipment satisfies international guidelines. There is no consistent evidence of health effects from RF exposures below guideline levels and therefore no reason why schools and others should not use Wi-Fi equipment.

And apart from bogus TV experiments, what do we know about the strength of Wi-Fi radiation in homes, schools and businesses? Kenneth Foster, a Professor of Bioengineering at the University of Pennsylvania, took 356 measurements at 55 different sites in four different countries to find out. Even though he took his readings close to wireless routers, in all cases he found that the radiation level from Wi-Fi was far lower than international safety standards and often much lower than other radiation sources nearby.  Wi-Fi is a new addition to modern life and no scientist can say with her hand on her heart that it is perfectly safe - particularly in the long term. But there is no theoretical reason to expect problems and no good evidence for any harm. Of course we need more research to understand its effects more thoroughly and also sensible precautions. But misleading and irresponsible scare stories serve only to cloud the issue.

Life in hypertext

My laptop needed some repair work. Limping by on a school machine during the day was made more than bearable by having the use of an iPod touch the rest of the time and access to an N810. None of these are my own. Of the three, the iPod touch is a revelation — so easy to use, the Gmail interface is (as of now) outstanding and surfing the web on it is often a joy. I don't yet know the N810 well enough to comment about it, but one thing that lets the iPod touch down is the laboriousness of entering text. I look forward to putting the N810's keyboard through its paces, but somehow I doubt it will prove as comfortable to use as the E70's thumb keyboard. The E70 is simply the best device I've ever owned for texting.

As ever when my laptop's down, I learn things. One thing I learned this time: wireless, mobile computing is getting pretty enjoyable all of a sudden. Like everyone else, I now want to try the Asus EEE. These are all devices we need to trial in school.

Meanwhile …

I  William Gibson (my bold):

One of the things I discovered while I was writing Pattern Recognition is that I now think that any contemporary novel today has a kind of Google novel aura around it, where somebody's going to google everything in the text. So people--and this happened to me with Pattern Recognition--would find my footprints so to speak: well, he got this from here, and this information is on this site.

(Sergey Brin and Lawrence Page, The Anatomy of a Large-Scale Hypertextual Web Search Engine — 1998, pdf: "Google is designed to provide higher quality search so as the Web continues to grow rapidly, information can be found easily. In order to accomplish this Google makes heavy use of hypertextual information consisting of link structure and link [anchor] text. Google also uses proximity and font information. … The analysis of link structure via PageRank allows Google to evaluate the quality of web pages. The use of link text as a description of what the link points to helps the search engine return relevant [and to some degree high quality] results. Finally, the use of proximity information helps increase relevance a great deal for many queries.")

II  Adam Greenfield:

… the book is an obsolete mediation between two different hypertext systems. For everything essential is found on the del.icio.us page of the researcher who writes it, and the reader who studies it assimilates it into his or her own blog.

What we're teaching this year

I thought I'd post here some links to stuff we've developed and are using with our first year students (13 year-olds). The material is in the public domain, on JotSpot.

So, here's the syllabus. (It's open to revision this year, as we teach it, and, of course, before we teach it again next year.)

Autumn Term

ICT at school, home ... mobile
Internet & web: key figures and events
Reading the social web: browsers, RSS and search
Communicating & collaborating, on- and off-line I: Office(s)

Spring Term

Communicating & collaborating, on- and off-line II: webmail, IM, chat, VoIP; blogs & wikis; video- and photo-sharing; social bookmarking and tagging; maps

Summer Term

Responsibility and Identity: Wikipedia (critical reading, responsible writing); social software (privacy, safety, digital identity)
The Law: copyright (links, permissions, problems); music (file-sharing, DRM); defamation and abuse (rights and responsibilities)
Games
Virtual Worlds   

Then there's a wealth of linked-to background material that served earlier this year as stuff for the department to immerse itself in as it readied itself. (We're very fortunate in the quality and commitment of the team which teaches this course.) I update this material from time to time so it can remain useful.

We've had fun delivering these within the constraints of time (one 40-minute lesson a week!) and the engagement of the pupils has been inspiring. 

In doing what we've been doing, my concern has been to leave behind what John Naughton called (in the Observer) the Old Person's ICT Curriculum. I also found inspiration along the way in Dave Snowden's blog post, Huginn and Muginn. Not everything there meshes with what we're doing (we're not delivering touch-typing and, yes, we should be) and we are teaching something of a body of knowledge (eg, about web history —€” Eliot: 'A people without history Is not redeemed from time' — but that's not what he was referring to: see 'don't teach ICT as if it was a "body of knowledge"'). Such things apart, I'm entirely at one with the spirit of remarks like these:

… make computers and broadband a universal right, like water … most computing skills and all social computing capability is learnt by doing and by regular practice rather than classroom lessons.

… what really matters is that children experience and contribute to the evolution of technology, and to see that evolution as a symbiotic relationship with human kind. That requires us … [to be] thoughtful and mindful. We don't need to sacrifice an eye to gain wisdom … but we do need to sacrifice an over explicit non-experiential approach to ICT teaching.

I also like his fifth point:

Let things emerge, don't plan … It's not so much about repeating a success as repeating the conditions which led to that success. In any complex system you can never replicate outcome, but you can replicate starting conditions. … you want multiple diverse initiatives to emerge, and you want to measure their impact on the social and educational fabric … not a series of pre-determined targeted outcomes.

There's been a surprising amount of room for things to emerge: pupils experiment in their own time, bring a lot to the table, anyway, and are excited by discovering more about the powers given them by contemporary computing.

I'd add to all this a word about the re-appraisal of Prensky's influential digital natives meme — a re-appraisal that has been going on for some time now. Here's Henry Jenkins (writing earlier this month):

Talk of "digital natives" helps us to recognize and respect the new kinds of learning and cultural expression which have emerged from a generation that has come of age alongside the personal and networked computer. Yet, talk of "digital natives" may also mask the different degrees [of] access to and comfort with emerging technologies experienced by different youth. Talk of digital natives may make it harder for us to pay attention to the digital divide in terms of who has access to different technical platforms and the participation gap in terms of who has access to certain skills and competencies or for that matter, certain cultural experiences and social identities. Talking about youth as digital natives implies that there is a world which these young people all share and a body of knowledge they have all mastered, rather than seeing the online world as unfamiliar and uncertain for all of us.

Teaching this course this year, we have had it confirmed that being born in 1994 doesn't mean that online life, for all that it may be familiar, is well understood: where it's come from, what it can do and what your options are —€” these are all things that unite adults and teens as we seek to develop and mature in this new and changing world.
