It is a strange paradox in the academic world that research that is often funded by public money and that should be of interest to many is then only accessible to a privileged few. The main objective of most researchers is publication in one of the major scientific journals and, of course, this is what really counts in your CV when you're aiming for higher positions. However these journals command hefty subscription fees and university libraries devote a large part of their budgets to journal subscriptions. So students and staff can read the research papers but they are essentially out of the reach of the general public. This immediately places a barrier between the researcher and the general public. Shouldn't research results be freely accessible for all?
This is the subject of an editorial article in The Guardian entitled In praise of ... academic wikipedians which examines the reluctance of academics to seriously get involved in more open publication. The scientific journals have a long established business model and one that clearly works and it is not surprising that they have not been so interested in open access. As the articles states:
"While the stated aim of academic journals is disseminating ideas, they throw barbed wire around themselves and keep the interested public out."
The principle of Open Access (research being freely accessible on the net in fulltext) has become relatively widespread but many journals have been reluctant to allow parallell publishig on open sites. The vital factor here is status. Publication in open access journals doesn't quite have the same impact as publication in the top journals and it's going to take time to change this entrenched pecking order.
But what about Wikipedia, the most comprehensive reference work ever compiled and the default source for millions every day? The article wonders why so few academics are intrested in contributing. Wikipedia is still generally frowned upon as an academic source but the challenge from Wikipedia is that if you don't trust what you read why not help us improve the information? Right now the Wikipedia Foundation Research Committee are carrying out a survey, Expert barriers to Wikipedia, to find out why there is so little academic involvement (read more in another article Wikipedia wants more contributions from academics). Since Wikipedia is often the first reference point for so many people (students, journalists, general public) it would make sense for the universitiesto get involved and make sure the information is comprehensive and trustworthy.
Once again the problem is status. Contributing to Wikipedia gives almost zero status on an academic CV and as a result there is no reason that faculty should devote hours to that rather than concentrating on work that gives results. Of course there are plenty of pioneers who believe in the principles of open publication and collaborative work but they are still a tiny minority and the mainstream faculty is still highly skeptical. Who can tip the balance?

What tech will we laugh at in 2031?
This old cellphone ad from over 20 years ago certainly makes me smile since I remember when gigantic brick-sized phones were status symbol number one and the ultimate executive accessory. I remember in the early nineties a mobile operator claiming that in the future everyone will have a cellphone and how nearly everyone scoffed at the idea. "Who needs a mobile phone," they would say, "why don't they invent something we really need:"
So much for needs analysis. If we based all research on what people think they need we'd be still in caves. Innovation involves thinking ahead of everyone else and daring to invest in things people don't think they need. I wonder what we'll think of today's innovations twenty years from now.

Facebook for learning?
Learning management systems like Moodle, Blackboard and many more are standard at most universities and in many schools. They're great for course administration, keeping all course documentation, assignments, discussion and teaching resources in one place. However many people see them as walled gardens and wonder why we can't simply use freely available social media as a course platform instead. There are many examples of empty and uninspiring discussion forums in the university's LMS whilst the real discussion between the students is taking plce elsewhere, for example in Facebook. So why not just use Facebook as your classroom?
This is the subject of an article on the Austalian Flexible Learning Framework, Is Facebook the next LMS? If all the students are already on Facebook why not move the discussion there instead of asking them to log into a less inspiring forum? There are some convincing arguments for using Facebook. It's a familiar environment for students and allows them to integrate study with leisure. There's no learning curve for new students and they can even let other friends in their network get involved in course discussion. It's also easy to access from all mobile devices and easy to participate on the move. There are plenty of cases of university courses using Facebook as a learning space, in particular the London School of Business and Finance who run a Global Master of Business Administration (MBA) course. The flexibility and ease of use is appealing as Francis Kneebone points out in the article:
"Imagine if you could market a course or conference where the learners just had to click ‘like’ to begin. It would make training very accessible indeed."
The drawbacks centre mostly around privacy and control. Should public education take place in proprietary environments like Facebook? Who owns the material placed there? Can the content be archived safely or can Facebook pull the plug? At present Facebook is a rather chaotic environment for discussion where topics that disappear under the horizon at the bottom of the page seldom turn up again. I belong to several discussion groups there and it's impossible to get an overview of all the discussion threads; something most LMS are very good at. An additional problem is the lack of file storage in Facebook making it impossible to submit assignments though if students posted their assignments on a blog or other website that could be overcome.
There's no doubt that Facebook is a more appealing digital forum than any LMS and maybe the solution is to keep integrity sensitive functions locked away in the university's own LMS but move the more open course discussions on to Facebook or similar. Whether Facebook is still the dominant social network in five years time is debateable but we need to find ways of facilitating mobility between our various social networks. A single sign-on solution that lets me log on to my personal learning environment and allows me to seamlessly move between tools would be the dream scenario.

All tagged up
At the moment QR-codes are being used mostly in advertising where you scan the code and can see more product information on a website. DIY chain The Home Depot have started using QR-codes to let customers access video DIY tips, product demos and further information. You can see how to use the product before you decide to buy. See more on Mashable, Mobile bar codes come to The Home Depot.
In education there are already many innovative applications of this technology, as well demonstrated in this excellent overview (below) by Carol Walker from JISC RSC Scotland N&E (see original post). QR-codes are used in libraries to help students access e-books and e-journas, to speed up borrowing and returning and for catalogue access. QR-codes around campus can be used to help new students get acquainted with the campus. Museums can have QR codes on every exhibit to provide extra information, activate video or audio commentary. Books can have QR-codes leading to new updated material. The potential is enormous.
At the moment this is still not mainstream. You need a smartphone and you need to download the application before QR codes become meaningful. Hopefully new mobiles will have a QR reader pre-installed thus eliminating one major hurdle. We're still waiting for the critical mass to be reached but the potential uses are so wide ranging that the only reason QR won't take off is that an even better solution emerges.
Basically everything could be tagged like this and you can't help wondering when we can have a bar code on our foreheads so people can find out everything about us without all the bother of engaging in long conversations.

Augmented reality gets even realer
I've been following the development of augmented reality (AR) with interest over the past couple of years. It's still far from mainstream but a breakthrough could come soon, especially since so many people now own devices that can cope with it. By viewing the world through your smartphone you see extra layers on top of reality. It can be links to more information on a restaurant, historical building, a house for sale and so on. You could see monsters on your street that you have to fight or see instructions on how to work some equipment in front of you.
If you aren't sure of what effects AR is going to have in the future have a look at this amazing film trailer. It's a German film where you play one of the roles and you see the action in AR through your mobile. You have to actually visit the action scenes and your reactions to each situation determine how the film continues. The potential for educational simulations are enormous; for training emergency situations, safety routines, military training etc. Here you can practice situations that simply cannot be practiced in any other way.
For some more thoughts on why all this is relevant to education read a blog post by Vicki Davis, A lesson in simple augmented reality.

Open introduction
There's an awful lot of uneccessary work in the world, especially in education. So many teachers preparing thousands of very similar lectures on the same subject. Universities and schools spending lots of project money to develop applications and systems that someone else has already developed. Thousands of similar videos helping new students with study skills or admission routines. I'm sure I've contributed to all this in my own way over the years but I often wonder if we could cooperate a bit more and stop thinking we have to reinvent the wheel all the time.
If we use more open educational resources we could free up enormous amounts of time that could be spent on stimulating student discussion. If we had better analysis of what our colleagues around the country/world are developing we wouldn't need to start so many projects to develop what already exists. Why not cooperate on producing a really good interactive course to introduce prospective students to university studies? That is exactly what is proposed by Dave Cormier in a recent blog post, An open university prep course - MOOC for basic skills.
His university, the University of Prince Edward Island in Canada, already runs a no credit online course for prospective students explaining the main principles of university education, study skills and general advice. In this post he's looking for partners to help turn this course into a MOOC (Massive Open Online Course) which could be used by students of any university. Since most universities have similar courses it would seem much more rational to pool resources and work together. The best material from various universities can be used and the teaching and administrative work can be shared. Specific local information must of course be produced locally but there is an awful lot of money and time that could be saved if could just work together. As long as those savings are then channelled into financing better teaching and student facilities.

The flip side and Khan Academy
There has been a lot of discussion in recent months on the concept of flipping the classroom. This means that instead of lesson time being devoted to the teacher going over the theory and then the students practicing at home, the lectures are watched at home on the net whilst classroom time is used for practice and discussion..
One of the most amazing success stories in net-based education is Khan Academy. Salman Khan started out by recording some maths tuition for his younger cousins on YouTube and noticed that other people also liked them. Now the website has over 2100 video lessons, mostly in maths, physics, chemistry and biology and has gained world attention, including the praise of big names like Bill Gates.
By offering all the explanatory lectures on the net Khan Academy allows teachers to flip the classroom; letting students watch the lectures at home and using classroom time for interaction and practice. Khan Academy also offers students plenty of exercises with the principle that you keep practicing until you get it all right. Teachers can let student go through the video material, track the class's progress and see exactly who is having trouble with what.
I know many who are a bit wary of net-based learning and wonder if this type of material is completely sound, whether there is a hidden agenda or whether this is the first step to dispensing with teachers completely. The answers seem clear however. If this material was not academically sound then it wouldn't be used by millions. The whole concept is the result of sheer enthusiasm and grassroots pressure without any commercial interests. Finally, the role of the teacher is enhanced in that he/she can now concentrate on really helping and tutoring instead of smply lecturing.
Watch the lecture below and judge for yourself but at the same time read an excellent post by Maryna Badenhorst, To flip or not to flip.She har drawn up a list of pros and cons on flipping the classroom and many of the drawbacks are well worth considering. In particular, who deletes obsolete lectures on the net? Outdated and inaccurate material will lie there forever and it's important that teachers revise the playlists they recommend to students. It is also important to stress that this method is just one of many ways to teach a subject and that a flexible mix is needed. Blended learning.

Light my fire
There are two radio programs that make Sunday mornings so pleasant - one features baroque and earlier music and the other features world music. I'm not an authority on either form but I listen every week, either live or later on the net. The reason I listen so regularly is largely due to the presenters. They both have a burning interest in the music they present and communicate that enthusiasm in an infectious manner. The same program with a lesser presenter would probably not have grabbed my attention.
It's much the same with education. At school I was good at maths and physics but the subject that I went on to study at university was English. That choice was not because I sat and objectively weighed up my future career options and made a rational choice. It was simply because English was fun and my teacher had encouraged my efforts at creative writing. I suspect many career choices have been inspired by one good teacher who has succeeded in lighting a fire.
There's a lot of debate about school today, mostly focusing on standards, quality criteria, learning outcomes and examination. It all seems so scientific and objective but I feel we're missing the most important quality criterion of all - enthusiasm. If a teacher can communicate enthusiasm and curiosity for the subject and inspire the students then that quality is often worth as much if not more than carefully planned lessons and well-formulated learning outcomes. Sheer infectious enthusiasm can compensate for less than perfect planning and slightly chaotic organisation and the positive effect of human energy on students' success rates should not be underestimated.

Now you see it, now you don't
Visiting friends' homes in the past I used to enjoy seeing their record collections. Most people were only too pleased to show off their collection and my musical education was developed by thumbing through piles of records and asking to hear the ones that caught my attention. Seeing other people's extensive collections inspired my consumer instrincts and my own collection was inspired by several friends. Comparing musical taste was a great way of getting to know someone.
Today the music collection is invisible. No groaning shelves packed full of records, just files on an iPod or a playlist on Spotify. Today's music is totally portable, extremely convenient and completely unobtrusive. However it has lost its ceremonial value. It took an effort to take the record out of its sleeve, put it on the turntable and start the player. As a result you sat and listened to the record and did nothing else, often in company. We really listened. Today I listen to music every day but nearly always while doing something else.
The same process is starting to happen with books. Soon our book collections will disappear online and our homes will not show evidence of our reading habits. Noone will see how much you read or what your interests are. Children growing up in homes with lots of books see that reading is important and will generally follow in their parents' footsteps. If they can't see evidence of their parents' reading will they be equally keen to read? A parent sitting with an iPad could be reading Yeats or playing Farmville; you can't tell from afar.
I love the digital revolution but can't help wondering where it is leading. We must be careful not to throw the baby out with the bathwater.

The genie in the laptop
This week's web discovery for me is a very attractive search tool called Qwiki. I've found myself searching images almost as much as text recently and there are many very attractive apps for finding high quality photos. The idea behind Qwiki, however, is unique as far as I know. You search for a town, person, restaurant, activity or whatever and Qwiki presents you with a photo montage about your search, reads an introductory text with the vital facts and presents lots of relevant links for more information. It is a fine example of a mashup featuring material from sources like Wikipedia, Google, YouTube, Fotopedia and others.
One slightly eerie thing about Qwiki is that the computer voice that presents the information has a soft female neutral American accent which reminds me strongly of the soft-spoken tones of the computer HAL in the film 2001 - A space odyssey. I can just hear her saying "I don't think that is a good idea Alastair."
The following film is from the product launch last year and features using Qwiki as your wake-up call telling you what today's weather will be like as well as what meetings you have in your diary. The genie speaks.

Do not disturb
Information overload and multitasking are fairly frequent subjects on this blog and it's time to revisit this theme. There has been a glut of articles on this theme recently, thus inducing stress at the overload of articles on information overload! Interestingly enough there is a summary of all these articles, for those who don't have time to read about information overload, 8 Must- Reads About Digital Distraction and Information Overload on Fast Company.
The gist of it all is that we are allowing ourselves to be interrupted at an ever-increasing frequency. We can multitask up to a point but then we become incapable of making decisions since we're taking in too much information. I'm guilty as charged I admit. It is increasingly hard to shut down the distractors and concentrate on one thing at a time. Even if most e-mails are relatively dull we can't help checking to see what's new - up to 40 times an hour according to a survey of office workers. The same goes for Facebook, Twitter and many other apps and it's easy for many to immediately jump to the conclusion that all this is a waste of company time.
An article in Newsweek, I can't think, describes recent research into our ability to make decisions when faced with too much information. A reasonable information flow can certainly stimulate our creativity and lead to good decisions but once you reach a certain level we face info-paralysis. If the volume of information is too great our brains just can't cope. According to psychologist Joanne Cantor:
“If you let things come at you all the time, you can’t use additional information to make a creative leap or a wise judgment. You need to pull back from the constant influx and take a break.”
So do we need to switch off and step back? Of course we do and we need to learn when to switch on and when to switch off. We need to relearn the art of attention. It's not just the teenagers who don't know when to switch off, we adults are equally guilty. Just look around at any conference or meeting at what people are really doing on their laptops and mobiles. Schools and universities must make more use of mobiles and laptops in the classroom but it is vital that some activities are tech-free. If the aim of a session is group reflection and discussion it is perfectly justifiable to ask for all devices to be switched off. It's a vital lesson for all to learn; we're here in this room and we're going to discuss but in one hour from now you can switch on again and search for further references. All age groups can benefit from structured non-tech time.
The art is to become multi-modal. Sometimes it's good to "go with the flow" and let all the social media stream in. I really enjoy seeing all the comments, tips, links and discussion and to be a part of it is stimulating. The tricky bit is to turn it off to focus on one important task and spend quality time with it. Sometimes we skim our way around various websites gathering notes and impressions for further use and sometimes we need to deep read an article or report. Some tasks go well with background music, chat sessions, Twitter feed and so on all at once and other tasks go best in silence.

In the bubble
We live in the age of personalization. Products and services can be tailor-made to our individual requirements and we can choose from a bewildering number of alternatives, all to make us feel unique and special. On the net we have Google, Facebook and all the others checking our on-line behaviour, remembering our preferences and then customising and adapting the information we receive according to our preferences. Several online newspapers, like the New York Times, now feature news items that your Facebook and Twitter friends have recommended so that you get the news you are interested in.
But there's a darker side to all this. At this week's TED2011 conference Eli Pariser spoke on the theme of his forthcoming book, The filter bubble; that personalisation is actually making us more uninformed. It sounds so positive that filters on the net help us to find the information we really want and that our friends' recommendations influence our search results. However the tendency that Pariser sees is that we end up only seeing information that confirms our present views, what he calls our "filter bubble". Information that conflicts with the preferences of my friends and myself are simply filtered out of the search without our being aware of the process. This unconscious filtering is worrying.
If all my friends share my political views I risk only seeing search results that we all approve of. Conflicting views are quietly discarded and we can be lulled into thinking that our views are correct. We can easily filter our news preferences on the net so we need never be disturbed by uncomfortable information. We risk being trapped in our own information bubbles.
Shouldn't we be able to switch off this well-meaning filter or at least be more aware that it is there? Is the wisdom of the crowd so wise if the crowd all agree with each other?

Open your textbooks
Today there are vast numbers of textbooks and course material on almost every subject freely available on the net. Much of it has been written by educators and is subject to continuous review and revision. Net-based material can be upgraded immediately to take into account the latest events in the world (the uprisings in Tunisia and Egypt for example) in stark contrast to printed textbooks which can often be up to 10 years out of date. There was a case recently of schools using textbooks which referred to the Soviet Union as a major power in the world.
So why then do we still insist that children and students should use printed material and cast doubt on the validity of the net-based material? This could even save schools and students a lot of money and free up the teacher to adapt and create the materials they feel will best support the goals of the course they're teaching.
So here's a short video with David Wiley of Brigham Young University explaining the advantages of using open online textbooks: Education without limits: Why open textbooks are the way forward.
So why then do we still insist that children and students should use printed material and cast doubt on the validity of the net-based material? This could even save schools and students a lot of money and free up the teacher to adapt and create the materials they feel will best support the goals of the course they're teaching.

Footprints
I've never liked writing my CV. It always takes longer than anticipated because you tend to analyse every word - does that sound too modest/boastful? do I really need to mention that?. They're generally extremely predictable documents full of buzzwords and politically correct information (everyone embraces change, enjoys challenges, welcomes diversity and has hobbies like wind-surfing, judo or mountain biking). I don't think this aspect of the CV will change but the way your career record is documented and where you put it are changing rapidly.
Employers today spend increasing amounts of time checking applicants' digital footprints and with so much information out there that the traditional CV is becoming completely obsolete. I've just read an article in Forbes called 5 Reasons Why Your Online Presence Will Replace Your Resume in 10 years. The ten year perspective seems extremely cautious and I suspect that social media are a key factor to finding a job today, at least in some areas of business. The key is to manage your digital presence and ensure that your experience and competence are as visible as possible to potential employers.
I've heard a lot about employers checking people's Facebook profiles before choosing who to interview but that is only revealing if the candidate is unaware of the privacy settings in Facebook. Much hotter in the employment market is LinkedIn which is all about career networking and allows you to write an online CV.
The point here is that our CVs are already online. We have our profiles and activities on variuos social media sites, our photos on Flickr or Picasa, our blogs, web sites and our contributions to discussion forums and suchlike. The problem is that our digital footprints are fragmented and haphazard. Anyone trying to find out about us will have to sift through many Google links and may find the right information but may equally stumble upon the less complimentary stuff. We need to think of out digital footprint as the new CV and try to take control of our net identity.
An article on Mashable, How to build the ultimate social media resume, gives some tips on how to refine your digital identity and there are undoubtedly hundreds of similar pages of tips. This I think should be a vital part of the digital literacy that schools should be providing. If young people can take control of their digital identity from the start and build up an online profile it will make them more interesting for future employees.

Campus or distance?
We still tend to see campus-based courses and distance courses as two separate worlds. The former is seen as having higher status since students and teachers meet face-to-face every day and there is a high degree of interaction. The latter is seen as a poor relation where students sit alone with their computers with only a discussion forum or e-mail to interact with faculty or fellow students. The stereotype online course is basically a traditional correspondence course and therefore no surprise that the success rates on such courses are generally rather low.
This is however a sadly stereotyped view and if you look more closely the boundaries get seriously blurred. Many universities have extremely large classes in the first two undergraduate years and the standard teaching model is the good old lecture, often one way communication with audiences over 100. How much interaction is involved there? How much learning takes place in the lecture hall? Isn't the lecture hall a case of distance learning? Is there any great difference between sitting in the lecture hall with 100 other students or watching the performance later on my laptop? This point is well described by Paul Hillsdon in an article called Why universities should ditch the lecture and go digital. Although there will always be room for inspired lecturing and some performances are best viewed live, there are still far too many that are niether inspiring nor interactive.
The real benefit of campus is being able to participate in seminars and tutorials in smaller groups where real discussion and reflection can take place. That is the most crucial element of all education and that is where real learning and insight can occur. However many cash-strapped universities have cut back on this, the one real trump card the campus model possesses. Many students complain that teacher contact hours have been cut over the last few years and as a result many campus students have alarmingly little "quality" teaching time apart from the customary lectures. In such cases you may start to wonder if some campus students are actually involved in "distance" learning. A good deal of my own student years were glorified self study to be quite honest.
At the same time we are seeing an increasing amount of online courses making use of various social media to increase the amount of interaction and discussion and ironically many "distance students" have much higher quality interaction with teachers and other students than many of their campus counterparts.
Campus students tolerate lack of contact and mass lectures because they are full-time and their loans and grants are dependent on them passing exams and staying the course. Part-time distance students are not so committed and will drop out if the course is not engaging enough. It's not a campus-distance problem, it's all about quality and in particular quality of interactivity. Courses that offer plenty of quality interaction between students and teachers will always retain student interest, whether they're online or on campus. The difference shouldn't matter.
