Raspberry Pi for Kids

This is a "Dummies" book, but don't let that put you off. From chapters on finding parts for your Pi and connecting it up, the book gets into its stride with projects in Scratch, Python, Linux and Minecraft, as well as other interesting topics like making your Pi work with a webcam.

Despite its name, the book is not dumbed down, and covers some quite sophisticated ideas. It is also clearly laid out. Definitely a good introduction to the hardware and how you can program it.

Introducing Computing: A guide for teachers

I haven't actually read this book from cover to cover, so this is a snapshot view if you will. Edited by Lawrence Williams,  a long-standing member of the educational computing community in Britain, the book is a good mix of ideas and the practical. For example, there is a chapter called Philosophy and Computing, as well as chapters on introducing computing into Key Stage 2 (primary/elementary school) and Key Stage 3 (secondary/high school).

It's also an academic book in that it draws on research, including original research, while managing to be interesting to read as well.

Brown Dogs and Barbers

Karl Beecher explains what Computing is all about, and provides an almost-excellent historical perspective. I say "almost excellent" because for me it is spoilt by the absence of Ada Lovelace. Nevertheless, in showing what makes the difference between an automated device and a computer, and the mathematical thinking behind computing, Beecher does a pretty good job for the lay person.

The Thrilling Adventures of Lovelace and Babbage


Ada Lovelace is recognised as the first computer programmer – even though computers hadn't been invented during her lifetime. She worked closely with Babbage, and saw possibilities in his Analytical Engine that had eluded even him. The Engine was never built, but this book imagines what might have happened if it had been. It's a great read, especially if you like graphic novels.

The New York Times Book of Mathematics

This is perhaps not an obvious choice for Computing teachers, you might think, a book on mathematics. But this one is fascinating because there are sections on cryptography and computing, as well as odd chapters on interesting topics like random numbers and electronics.

The subtitle of the book is More than 100 years of writing by the numbers. In other words, this is a collection of articles taken from the New York Times over the last 100 years. It's readable for non-mathematicians (well, mostly), and gives you a great historical perspective of how computing – and thinking about computing – has developed over that time.

Perfect ICT every lesson

This book by Mark Anderson, aka @ICTevangelist, is, I have to say, pretty good. Although it's not very long (129 pages before we get on to the references section), it packs in a lot of good, practical advice.
There are good sections on the SAMR and SOLO models, though Bloom's Taxonomy seems to have been omitted -- perhaps because it is already familiar to many teachers.

I liked the fact that the ideas are not only good, but doable. Also, it's good that Anderson provides information about useful programs along with their website addresses.

It's pocket-sized, and I think if I were new to use education technology in the classroom then I'd carry this around with me and dip into it every so often for inspiration.
I have to admit to having some doubts about this book even before I opened it. First, I was in the classroom for 22 years and in all that time I never once delivered what I considered to be a perfect lesson. If you're a teacher you will immediately identify with this: there is always something more you think you could have done, another tweak you could have made to that activity, a perceived missed opportunity for a great, if tangential, discussion.

I did once, as an Ofsted inspector, observe what I considered to be a perfect lesson, but even then that was my subjective interpretation of the Ofsted (England's inspectorate) criteria. So I wuld take the word "perfect" with a pretty large sack of salt.

Second, the tem "ICT" in the title is unfortunate, given that, in England at least, it is now regarded as a damaged brand. Given that the book was published in 2013, meaning that it was probably written in 2012, I think that could probably have been changed at the last minute (the title, not the brand).
Third, the frequent references to Ofsted, no doubt a strength when the book was first published, now date it to some extent because there has been at least one update to the Ofsted "rules" since then. In my opinion, lessons should be good in themselves, and achieve (for the pupils) what they were intended to achieve. If they do, then they should satisfy Ofsted criteria anyway -- and if they don't, then probably the criteria need changing.

Despite these initial doubts, however, I found that the advice doled out by the book still stands. Perhaps some of it will need to be adjusted in the light of the most recent update to the Ofsted criteria (substantially in September 2015, with a relatively inor update in January 2016), but that would be a matter of fine detail. On the whole, good practice should stand the test of time. Three years after publication, the advice given in this book still does.

One-upmanship

What can we learn from an academic and humorist who was writing around 70 years ago?
I've started to read and write about things that are not directly concerned with education in general, and education technology in particular, but which in my view have a bearing on it. That's how I came to consider writing about the work of Stephen Potter.

Background

Potter was a lecturer in the English Department at the University of Oxford, England, and also wrote and took part in radio programmes. However, he is best known for the "upmanship" books.
The first of these was Gamesmanship, or the art of winning games without actually cheating. Then came Lifemanship, the application of the principles of gamesmanship to everyday life. Graduates of the (fictitious) Lifemanship course were known as "lifemen". Next came One Upmanship, and then Supermanship, which was about how to stay on top.
The basic principle of one upmanship was that if you're not one up, you're one down. Put like that it all sounds horribly negative, but in fact Potter was gently poking fun at snobbery and academia.
I think there are five areas in which Potter's observations are worth bearing in mind today. I've seen examples of every one of these in the field of ed tech research and practice, and I expect you have too.

Dangling statistics

You've no doubt heard of dangling modifiers, which are words that are detached from the word or phrase they are meant to be attached to (or not attached to anything at all), as may be seen in the following sentence:
"Looking into the distance, the bridge seemed to be safe enough."
It sounds like the bridge was looking into the distance, rather than the person speaking. Thus the word "looking" is the dangling modifier.
Well, one of the things Potter highlighted was what I have decided to name "dangling statistics" – stats that seem to have no bearing on anything at all, ie no context, and no purpose.
For example, in the introduction to Lifemanship, there is a footnote which reads:
"According to Hulton Research, the number of lifemen who drink tea but never buy fireworks is 79… The figure for those who are interested in soap substitutes and have not yet been to Portugal is, however, 385."
These sort of statistics are not only pointless but meaningless too: what do we actually learn from it, and how could we possibly benefit from knowing it?
But the interesting thing about it is that it looks like it should be important and relevant. After all, the research has been carried out by a body with the august-sounding name of Hulton Research (see below under "OK names"), and the numbers quoted are very precise – not, "around 80" but "79"; not "nearly 400" but "385". This gives the (spurious?) impression of accuracy.
In our field, that of ed tech, I come across dodgy-sounding statistics all the time, especially in speeches by politicians.
Rather than go into great depth here, I refer you to my article The world according to Potter: Part 1 – Going metric.

Inventing terminology

Many of Potter's terms lend a spurious academic air to his writing. For example, there is Doctorship, Lectureship, Chairmanship, Carmanship, Lowbrowmanship, Highbrowmanship and even Hands-across-the-sea-manship. There's another example of impressive-sounding but invented terminology below.

OK Names

This is the use of names that sound impressive. In one of his footnotes, Potter advertises a booklet called "Places where it is OK for things to first come to you at".
In a note on OK words, he states:
"We hope to publish, monthly, a list of words which may be brought into the conversation and used with effect because no one quite understands what they mean, albeit these words have been in use for a sufficiently long time, at any rate by Highbrowmen, say ten years, for your audience to have seen them once or twice and already felt uneasy about them."
In yet another section, Potter discusses OK names:
"Just as there are OK words in conversationship, so there are OK people to mention…"
In How to Lie With Statistics, Darrell Huff mentions Potter and his OK names:
"It may take at least a second to find out who-says-so. The who may be hidden by what Stephen Potter, the Lifemanship man, would probably call the "OK name". Anything smacking of the medical profession is an OK name. Scientific Laboratories have OK names."
If you think about it, "Hulton Research" is a prime example of an OK name.
In his book Doctoring Data, Dr Malcolm Kendrick states that:
"… in the vast majority of cases, around 80%, the evidence used was the lowest level… otherwise known as "expert committee reports, opinions and/or clinical experience of respected authorities. This would otherwise be known as medicine based on anecdote by important professors. Or, as one wag has put it, this is 'eminence-based medicine'."

Stating the opposite of what you actually mean

A good example of this was the Supporting People initiative some years ago in the UK. This concerned funding for services like sheltered accommodation for vulnerable people. As soon as I heard the name of the new initiative I thought "They're going to cut the funding", and I was right.
It's the same sort of naming strategy that companies employ when firing people, eg enhancing their future career opportunities.
Potter deftly combined this stating of the opposite with an invented term: the petrification of the implied opposite.
Also see The world according to Potter Part 2: Opposites attract for more on this.

Inspection

If you're overly concerned with a visit from Ofsted (the schools' inspectorate in England), you might take a leaf from Potter's section on "Counter-inspection play", in Supermanship. He recommends rehearsing a special inspector lesson:
But of course no good inspectorman would arrive the day he was expected. In later, more experienced days, I used to ring up Inspectors and say 'I think you'll enjoy the discussion tonight'. Amazingly, it worked. Tipped-off class would respond brilliantly to rehearsed inspector-lecture.
I feel that at this point I should declare the usual disclaimer!

Conclusion

The "upmanship" books may have been intended as a huge joke, but what made them so powerful and so timeless is the fact that most of the things he describes have more than a grain of truth in them.
