It’s here, it’s here!!
We’re all a bit excited today at Curatr HQ – it’s here!!!
After a year or so of development, we’re very pleased to announce today that we’ve officially launched our new platform to power Social Learning – Curatr.
Check our new website at www.curatr.co.uk and have a look see our flashy video:
Or if you want a slightly more long-winded version (with a dog asleep in the background):
Harry Potter and the future of the Textbook
The Daily Prophet is the newspaper of choice for the discerning witch or wizard, this much we all know. With moving pictures and articles on every topic of interest, the Prophet is a fine advance on the offerings afforded to us muggles.
Or is it? You see I’m increasingly of the opinion that JK Rowling aimed too low with her imagination on this part. She couldn’t foresee the way in which things like newspapers and textbooks would really be consumed if the magic (read: technology) was widely available.
To take you further in to the future of textbooks, I first have to take you back, way back…
Socrates, he of Ancient Greek persuasion, was said to have lamented the adoption of the written word for scholarly activities. So much did he lament it that his student Plato wrote it down, presumably without his master’s permission (the first data protection violation in recorded history perhaps?). Socrates claim was that true knowledge was built-up in memory through the use of spoken stories and fables.
Fast forward to the 1400’s and the emergence of one Johannes Gensfleisch zur Laden zum Gutenberg. Gutenburg, as his mates called him, is widely regarded as the inventor of the Printing Press. His invention was the technology that enabled textbooks to exist.
Schools had already been around in documented history for some time (my own secondary school was founded in 1440) but they were places that followed Socrates’ techniques more than those methods we use today. Teachers were in possession of the tacit knowledge of the world and they used the classroom to impart their knowledge to students. Increasingly however, the need for more explicit knowledge was emerging. Specifically the need for standardised, explicit knowledge which would help to classify our world and aid both learning and teaching.
This could perhaps be termed the problem that textbooks were originally designed to solve: The increasing demand for explicit knowledge in an unstructured world. It took centuries for books to move from Gutenburg’s invention to the classrooms of the world, but the rest, as they say, is history.
Fast-forward to today and its easy to suggest that the problems that led to the invention of the textbook aren’t necessarily ones that we face today. Explicit knowledge is in abundance. Many might suggest that too many people have started writing their thoughts down for others to read. Our knowledge of the world today is highly structured and organised – a place for everything and everything in its place.
It’s fair to say that E-textbooks haven’t really taken off yet. In fact, anecdotal research like that carried out by Esther Wojcicki is telling us that some proportion of the population is stuck in Socrates mode. They are lamenting the onslaught of the E-textbook before it’s even really begun to arrive.
Mostly they have no good reason; it strikes me as being quite a defensive and vitriolic response which belies a true understanding of the change they see before them. Like JK Rowling, these students have failed to appreciate the shape and the size of the change that is coming.
To find out more about the future of the textbook it is useful to draw analogies to the music industry. Previously we all brought our music on CDs – I hear there used to be things called cassettes and before that, vinyl, but it sounds like a far-fetched story to me. CDs still exist of course but the demand for them has fallen considerably thanks to rise of platforms like iTunes. This allows us to purchase music with greater granularity than before (no more ‘B-sides’) and gave us an easy method to process micro-payments.
But now we are on the verge of another breakthrough change in the music industry; on-demand.
Music services like Spotify are changing the way in which people consume music. Previously we liked the tangible asset we got when we brought a CD. ITunes took away that physical object and introduced us to the idea of buying something that was digital. Spotify takes this a step further; if we aren’t going to physically own anything, then why buy it?
Surely it would be better to ‘rent’ it for the period of time you want it? Spotify, we7 and mFlow are just some of the names that are working from this principle. They give you access to a world of music whenever you want for a price (sometimes that price is free, with adverts, but most will push you towards a Premium Service for a monthly subscription).
The future of textbooks
This, I believe is the future of Textbooks.
E-books have a place. Specifically they work fairly well for books with a distinctive narrative that need to be read one page after another. That simply isn’t the case with Textbooks. In most cases you don’t need to read Chapter 3 before you read Chapter 17. In fact many Textbooks go out of their way to interrupt your flow of reading, introducing shout-out boxes with examples etc…
Publishers have spent the last 10 years building a huge amount of content that backs-up the printed book in the form of additional digital assets. Like record companies before them, Publishers have a massive back catalogue of content that they would love to make more money from. This is the opportunity to open up this mountain of content to the masses.
In my scenario I wouldn’t envisage readers really ever downloading a complete book; how iTunes broke up the album, I expect Publishers to break down their written content to smaller and smaller grains.
If the platform were to be social at the same time, then we’d generate a situation where users could curate learning content for their own use and publish these collections as guides for their follower’s to use. Over the life of a subscription a user would build up a very rich resource of content which they found useful; a guide to how they learnt everything they needed for a 3 year course at university for example.
It goes without saying that this platform would need to be delivered via mobile and, right now, the best candidate to make that happen is the iPad. This is the only device I have seen that is both portable and rich enough to deliver this experience so far. I’m sure many more will follow suit as the advantages of the device make themselves clearer and it defines its place in the hardware marketplace. But as it stands, this is the only way I would deliver written, visual, audio and cloud-based content to a handheld device.
In terms of the software to make it happen… Well that would be Curatr of course!
The Spotify model has attractive financial implications for both Publishers and Consumers of textbooks. It’s no great secret that the way in which the textbook marketplace operates is somewhat broken market. Students today are spending an average of £1,200 on books over the length of a university degree course. Publishers are searching for more and more ways to unlock the revenue streams that could exist for their back catalogue. Right now they make a substantial amount of their money from a tiny minority of their lists.
Of course money was never a problem for Harry Potter. But you can imagine the savings the Weasley family could have made over the lifetime of their children’s studies…

Curatr will get you laid!
John Nash sits awkwardly and alone, surrounded by papers and a half-drunk beer in a smoky 1940’s bar. His peers gather around him, captivated by the blonde woman who just walked in. They sit; smoking and drinking whilst pontificating on which one of them will bag the blonde. Each agrees that the others have no chance with her, but they are willing to back themselves. Nash sits quietly, pencil twiddling in his hands. His pondering on game theory reminds him of the competition for the blonde he is witnessing. A smile creases across his face as a magical moment of connection occurs in his mind.
“If we all go for the blonde and block each other, not a single one of us is going to get her” starts Nash. “So then we go for her friends, but they will all give us the cold shoulder because no one likes to be second choice”. Heads nod in agreement; we’ve all been there before. Nash continues, “But what if none of us goes for the blonde? We won’t get in each other’s way and we won’t insult the other girls. It’s the only way to win. It’s the only way we all get laid”.
Nash’s friends look sceptical at best. It’s a nice idea, but competition is competition; even Adam Smith said the best result comes from everyone in the group doing what’s best for himself.
“Incomplete!” Nash blurts out, his excitement no longer containable within his mind alone. “Incomplete, okay? Because the best result will come from everyone in the group doing what’s best for himself and the group”.
Such is the story of John Nash’s foundations for his “Nash Equilibrium”, as re-told by the 2001 Ron Howard film, A Beautiful Mind. Supposedly it was this realisation that lead Nash to the concept that something as fundamental as Adam Smith’s principles were actually incomplete.
Simplistically speaking, Adam Smith’s notion that players in a market will do entirely what is best for themselves was refuted. Nash proved that it would be a better result, mathematically, if they all did what was best for themselves AND the group.
Recently I’ve been working on the notion of cooperation and competition in education for our new Social Learning platform, Curatr. Cooperation is a fundamental concept in the field of Social Learning; that if the actors in a piece think and work collectively they will gain benefit above and beyond working in isolation. There’s a lot of support for this approach in online learning, not least because it fixes some of the stuff we broke when we left the classroom for E-learning.
On the other hand, competition is a hotly disputed concept in education. Traditional education systems are set for competition throughout their framework, with grade scores and attainment being at the pinnacle of this system. But the true benefits of such a system are disputed strongly by researchers like Alfie Kohn. His work is well documented and well argued, but for me the most obvious principle is that, in any competition, you will have a winner and whole lot of losers. It’s this kind of thinking that leads us to believe that competition is inherently bad. This is Adam Smith style competition however; everyone wants to be the best, so they further themselves but only one person emerges victorious in the end. This sort of behaviour is typical of Zero-Sum games and what Game Theorists might call Strictly Competitive behaviour. This can be changed in a Non-Zero-Sum environment however.
Cooperating in Non-Cooperative Games:
It might sound like a misnomer, but it isn’t. In Game Theory the idea of “non-cooperative” is very specific – it indicates that players make decisions independent of each other. In Curatr we have an environment in which each player is free to pursue the strategy they wish to.
Game Theorists have a method for plotting and calculating the best strategies for a given situation in what they would call a pay-off matrix. Below is a simplified version of the pay-off matrix for going home with the blonde, where the possible strategies between two players are going for the blonde first, or going to the friends.
Pay Off Matrix - the Blonde in the Bar
If every player in the group goes for the blonde, they all strike-out, as they block each other. As soon as Player 1 escalates his strategy to get the Blonde, the others are forced to follow suit, after all, why would you let your friend go after the Blonde, she is the best possible outcome of acting alone. But you are not acting alone, you are in a group and of course now everyone blocks each other and the Blonde’s friends subsequently tell them to “Go to Hell!”
Because of the nature of the game, where you act as a part of a non-cooperative group, the best possible outcome of acting alone isn’t open to you. The group will respond to your strategy, so going that way is a recipe for disaster. You must adopt the best strategy for you AND the group, which in this case is the bottom right cell, Everyone Gets Lucky.
Now let’s make a leap into the world of Curatr, which is a competitive environment where it is possible for you to “win”; to come first. Coming first will be the result of contributing, sharing and viewing more than anyone else, which will take quite a lot of hard work to achieve. In our payoff matrix we will list two possible strategies – “First” to represent the strategy of coming first and “In The Pack” to represent a strategy of contributing about as much as everyone else in the group. Note that we eliminate a 3rd possibility, contributing nothing, because without contribution you cannot progress through the game at all.
Pay Off Matrix - Curatr
As soon as a player decides to adopt the “First” strategy, the others in the group go with them (“Go To Hell if you’re coming first!”), all adopting the same strategy so as to avoid being left way behind in a race to the top – the desire to win still exists. But by adopting this strategy there is a constant one-upmanship, which grows the content exponentially. Here “Information Overload” occurs and the players block each on the route to success.
The best strategy for themselves AND the group is actually the bottom right, seeking to contribute enough to be “In The Pack”, but never seeking the glory of coming first.
OK, so what?!
Curatr is a game-like environment because we believe that elements of games and gaming are absolutely key in promoting user engagement (see the book, Total Engagement, for others working in this area). We allow users to compete with each other, but significantly, coming first is not the goal of this competition. The best strategy for playing Curatr is to cooperate with your peers in order to maximise the outcome, without any single person stealing the glory.
If the hot blonde in the bar is the best possible outcome for a single player, then we have created a system that encourages players to go for the friend, which is the best possible outcome for the individual AND the group.
So there you have it. Curatr will get you laid.
Curatr Beta – new version
For those of you lucky enough to be on the Curatr Beta (hint: click this link to emulate their success) we’ve just released a new version. Because we’re imaginative we’ve called this version “0.2″. Here’s a small video to celebrate that:
Headlines:
- We got some great data from our experiments – thanks for taking part.
- All of you are now on the same platform, with all the features we’ve made available so far turned on.
- The biggest changes are in the navigation (old one was too confusing) and the social aspects.
- Now each user has their own “canvas” on to which they can share objects or add new.
- You can then choose to follow new users to help give a different perspective on the learning.
- Everyone now has their own classroom, of which they are the administrator.
- You can use the admin link (check your emails) to invite up to 20 people to view your Curatr Classroom.
As always, the more feedback the better. We’ve still got a way to go before we’ve showcased the full functionality of Curatr, but we’re getting there!

Curatr Beta Update: Getting Social
A couple of weeks ago we launched our first versions of the Curatr Beta trial. We placed our testers into 8 groups and offered different features for them to play around with. The initial findings of these tests look to be quite compelling and we’ll be sharing them just as soon as we can.
We also got lots of great user feedback from this first round of testing and we’ve made a few changes in response to this. Screen casts like that from Noah Sparks were invaluable in showing us how people started to use our system and where it was falling short.
So, what’s new in version 0.2?
Your own playground:
Those of you on the beta will know that so far you’ve all been playing in a single large sandpit. This is great for a quick experience of what the product offers but it doesn’t help you to start realising your own use of Curatr. So for this next version everyone will get a sandpit of their own to play in as well. Here you will be able to upload objects, define collections, levels and guides and to enrol other users to participate in your testing.
We’ve been spending a good deal of time designing the flow of information in our “Add an Object” section; it was released pretty raw and whilst a lot of people had a great go at it, filling it out wasn’t easy. The modifications we make here should make this process significantly easier and much more robust.
We’re getting social:
In our first version we presented users with an object-centric view of the world. You could highlight individual contributions, but we hadn’t yet implemented proper “follower” features or sharing. This is all about to change.
Now when you enter into a Curatr Classroom you will notice a Peer is at the centre of the Objects. The Objects on the page are those which that Peer has shared. By following new Peers you can get access to other people’s home screens, collections and guides.
The experts view of the objects will remain the default selected and from this point going forward this person is known as the “Curatr”. As you go and browse through the Curatr’s Objects you can share objects you like by hitting the “share” button. This object will then become a part of your home page.
Finding new followers is something which we will be implementing over both this version and the next. We’ve got something pretty good in-store for organising your peers but we can’t fully implement that in this next version, so it will have to wait!
New Navigation and Search:
I was over the moon when a Twitter user picked up on the fact that previous navigation bar “looks like the Hitch-Hikers Guide to the Galaxy”; my constant source of inspiration. But despite this, it had clear flaws. It was slow in places, was poor for filtering guides and a complete pain for us to code. It had to go.
So we’ve gone back to basics now, simple being best. Our navigation now makes it very straightforward to select Collections, Sub-Collections and Guides at any stage of your viewing. It also enabled us to implement a fantastic search capability which alters the canvas in real-time given your input; check out the screen shot.
That’s it for now!
Version 0.2 should hit sometime next week if our internal testing goes well and we hope you’ll continue to give us your feedback and your opinion on what we’re doing.

A quick note on the forthcoming Curatr private beta
Firstly, let me say that we’ve been overwhelmed by the level of enthusiasm we’ve seen for our idea in the last week or so – truly. Thus far our private beta has had signups from around 150 different organisations, covering 28 countries from all over the globe. We’re seeing interest at every level of education, from schools to corporates. So thank you to all who have taken the time to view our website and signup; you will make this experience a whole lot better for your time and effort.
To the business of what we intend to do…
Well first of all, this won’t be quite like a normal beta test. Because we’ve got academic interests in the outcome of this testing, we’ll be splitting participants into one of a few different groups to try out the software. Each group will have a slightly different experience, be that the features on offer, the other people you interact with or the subject matter.
Initially we are going to get participants to test in collective areas. This means you won’t be “getting” your own Curatr to do as you want with right away. Testing social software in isolation isn’t really a test!
We’re going to be collecting feedback as we go and we’ll then be looking to iterate quickly, adding features and fixing bugs on the fly. At the moment we’ve scheduled 5 feature releases, taking us from Beta 0.1 initially, up to 0.6.
Right now we’re modifying Curatr as a result of internal testing. I expect this to last a week or so, then we’ll launch the beta.
We’re going to leave the private beta signup live for this time, so its not too late to get involved if you still want to. Please visit www.curatr.co.uk and fill out the little form in the lightbox window.

Curatr – a new platform for online learning
I’ve been a little bit radio silent over the last couple of weeks as we’ve approached the soft launch of our latest creation, Curatr. But now it’s finally time to break cover and see if we can get people as excited about our little creation as we are. So that’s what I’m going to try and do!
First of all, a flashy video. Sorry, but it will actually benefit your understanding of what we are trying to do here and I can’t explain it any better in less than 2 mins!
So fundamentally, Curatr is a new platform for delivering learning experiences over the web. It is the result of us trying to marry-up some great new approaches that have been emerging themes in E-learning for a little while now. At its core are a couple of key principles:
• E-learning works best as a two-way process.
• We can learn from anything.
We’ve added a few more facets to the central tenets as we’ve gone along and there is any number of buzzwords that you can use to describe them. We’re talking social learning, personalised learning, mobile learning, learning by exploration, games based learning and many more.
The upshot of all this is that Curatr is what you make of it and I wouldn’t want to suggest it is the be-all and end-all answer to any of those genres. But it certainly takes a leaf out of their respective books and allows for users to create a learning experience built around whatever approach they deem most suitable. So long as it keeps the two key principles.
The result is something quite different. And, in order to practice what I preach, I made a video in order to explain it, instead of you having to read pages of my waffle!
Right now we are looking for private beta testers to help us bring the project along in the next few weeks. Head over to www.curatr.co.uk to find out more, watch the same videos again and sign-up to the beta.
We’re looking to deliver our first public release as quickly as possible and I promise some innovative approaches to the commercial proposition that goes with it.
I’ll be talking more on the blog about the theory behind it and the features we incorporate but, in the meantime, if you’ve got any questions for me please feel free to put them in the comments here!
Managing the Social Learning Mess: Auto-curating content
Let us suppose that we’ve created a social approach to online learning, where-by our users not only take content from our Learning Environment, but actively add content to it as a part of their participation. One of the biggest problems facing those tasked with administrating such a platform is going to be information overload.
I admit this stage is somewhat ‘down the line’ in terms of a successful social learning environment, but to ignore planning for this would be short-sighted.
Simply leaving the task to administrators is not often a viable option; online learning is supposed to cut administration work, not make it worse. Developing a good taxonomy and naming convention can certainly help to spread the load, but this too has limitations.
What is required is a method of ‘Curating’ the content that your learners contribute. The role of the Curator is a vital one; sorting the wheat from the chaff and bringing some sort of order to what would otherwise be chaos.
Curators also go beyond these functions and use learning objects to tell us a story, providing deeper insight into what would otherwise be just a collection of ‘things’. But the job is a difficult one, requiring a subject matter expert and a good deal of time; see this post by Jeff Cobb on the need for good content curators.
In developing our new software, we’ve been looking into ways of “auto-curating” content which learners contribute to the learning environment. This is just one piece of a much larger puzzle that our latest product seeks to address, but it is a vital piece none-the-less.
A bit of background on how our learning environment works:
Learning objects are first of all organised into collections. Collections can be as be as big or as small as the editors of the learning environment deem appropriate. For example we may have a “dinosaur” collection, or perhaps we would look to do things at the level of the “T-rex”. Indeed, for those of us very involved in palaeontology we might choose to make our collections at an even ‘lower’ level, for example “the foot bones of the T-rex”.
Within collections sit objects. One object can exist in many collections. Objects can be any piece of digital information, from a web-link to a video, to an animation.
These objects carry with them an array of metadata, including details such as keywords. It is relatively easy to suggest that an object is like another object by using these details, but it is not a perfect match. And when we open our learning environment to contributions from all-comers, it is not easy to enforce a metadata tagging system which is always used, or always used correctly. Such data also fails to take into account the perceived quality of a learning object – do a lot of people view this object and rate it as a worthy object?
What if we could tell that an object was like another object without it actually sharing any metadata at all? We would be then in a position to automatically suggest which learning objects were related to each other and to start the Curation process without the need for human intervention.
Using a range of semantic web techniques, this is what we have attempted to do. Firstly, by adopting the Resource Descriptor Framework (RDF) in storing our learning objects, we are able to discover a lot more about the objects.
For example, think about Wines (I tend to veer towards alcohol metaphors when things get complex). The following statement breaks down the Stonleigh Sauvignon Blanc into an RDF readable format: (example taken from W3C)
SauvignonBlanc rdf:ID=”StonleighSauvignonBlanc”
locatedIn rdf:resource=”#NewZealandRegion”
hasMaker rdf:resource=”#Stonleigh”
hasSugar rdf:resource=”#Dry”
hasFlavor rdf:resource=”#Delicate”
hasBody rdf:resource=”#Medium”
SauvignonBlanc
Because of the way in which the information contained here is broken down, we can tell on a number of levels what a Stonleigh Sauvignon Blanc is like. It could be grouped with other Wines which are of Delicate flavour. Or perhaps we just want to group it with other Wines produced by the same Maker – Stonleigh. Or we can use combinations of multiple nodes to infer which wines the Stonleigh is most like.
Outside of RDF, we can also infer an amount of information about an object given other objects that we know connect to it in someway. Our software allows users to connect objects together as a part of their own “guides” – a way of knitting objects together to create a logical sequence of learning. Where these guides include some objects which share metadata, and some which do not, we are able to infer if an object is like another object.
Taking a crowd-sourced approach to grading our learning objects, we can also discover more about the usefulness of an object and its quality. This allows us to curate objects to not only find like objects, but also to find like objects of a certain quality.
In short, by utilising a number of semantic web techniques, we are aiming to create a learning environment that has the ability to organise any amount of content into suitable categories automatically. There remains a need for human intervention at some levels – for instance, the final “sense” check before things are sent live – but the workload is vastly reduced.
This is just one of the innovations we are looking to introduce with our new software, which we’ve aptly named Curatr. I’ll be blogging more on the features of Curatr in the coming weeks, but its safe to say we’re pretty excited about it.
