Restarting Computing in UK Schools

A somewhat more down-to-earth post, this one; an overview of, and a case study in, the wonderful revolution in Computing and Computer Science currently taking place in British schools.  Adapted from a paper presented at the 4th World Conference on Learning, Teaching and Educational Leadership and published in the Elsevier ‘Procedia – Social and Behavioral Sciences’ journal.

The past few years have been challenging ones for Computing education in the UK.  After decades of national neglect, largely overlooked, from the county that invented Computer Science, there has been a sudden impetus to reintroduce computational problem-solving into the school curriculum.  Immediate obstacles include a generation of children with no CS background and a need for tens of thousands of new or retrained teachers.  The Computing At School (CAS) movement has been instrumental in this quantum transition from an IT to Computing syllabus, as have the British Computer Society (BCS), leading UK university CS departments and a number of major international technology companies.  This piece looks at the background to this position and the progress being made to address these challenges.  It describes, as an example of many, the work of the BCS-funded Glyndŵr University ‘Turing Project’ in introducing Welsh high-school students and staff to high-level programming and ‘computational thinking’.  The Turing Project uses an innovative combination of Lego NXT Mindstorm robots, Raspberry Pi computers and PicoBoard hardware together with the Robot C and Scratch programming platforms.

The Problem with ‘Futurology’

What’s your favourite terrible technological prediction?  There are plenty to choose from, that’s for sure.  The following is just a brief list of the most infamous computing-based futurology howlers (oldest to newest):

  1. “I think there is a world market for maybe five computers”, Thomas Watson: IBM chairman (1943) (* or was it someone else?)
  2. Computers in the future may weigh no more than 1.5 tons”, Popular Mechanics (1949)
  3. “I have traveled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won’t last out the year”, Prentice Hall: Business Books Editor (1957)
  4. “There is no reason anyone would want a computer in their home”, Ken Olsen: DEC founder (1977)
  5. “640K ought to be enough for anybody”, Bill Gates (1981) (* or did he really?)
  6. “We will never make a 32-bit operating system”, Bill Gates (1989)
  7. “Spam will be a thing of the past in two years’ time”, Bill Gates (2004)
  8. “Next Christmas the iPod will be dead, finished, gone, kaput”, Alan Sugar (2005)

The ‘Real’ Internet of Things

(This post is derived from a talk given at the 2012 Wrexham Science Festival.)

There are so many different ways of describing the Internet of Things.  On the one hand, maybe it’s what the original Internet was always destined to be; on the other, it’s about as boring as it gets.  Tag just about anything and everything we can stick a label on, let them talk to each other, then turn the existing  Internet into a massive database of things that can be referenced, interconnected and used any which way we like.  Great if you really need your fridge to reorder the milk for you or the plants to water themselves but hardly inspirational.  Two features, however, give the proposed (and not yet fully considered) IoT a serious ‘Oooh!’ factor …

Firstly, the ever-increasing intelligence of the Internet will allow us to manipulate this data in new and exciting ways.  More and more, the evolving Semantic Web will be able to understand the information it’s working with and make the best use of it for our benefit.  Our personal and working lives are about to become completely automated and made easier by web intelligence.  Secondly, and potentially on the darker side, other hardware and software developments will extend the IoT’s reach.  Face-recognition, image-scanners and numerous other advanced detectors and sensors will soon mean that everything can be read, whether it’s deliberately labelled or not.  We, and everything we use or own, may soon become part of the Real Internet of Things (RIoT) and we might have to expect to be identified and traced in everything we do.  So what will the future will look like?  Are we heading for paradise or Big Brother?
