Khan Academy: The Future of Education

Khan's YouTube channel hosts more than 1800 lectures on classic school topics. On demand video tutorials could revolutionize education.
Will the school of the future need teachers? Probably. Will it need classrooms and textbooks? Hopefully not. To see what will replace them you only need to look to the ever expanding and educational Khan Academy. Originally developed as a means of helping his cousins with math, Salman Khan’s efforts have expanded into 1800+ videos on YouTube, with nearly 22 million views between them. In these brief 10-15 minute tutorials, Khan explains basic (and not so basic) math concepts in a concise manner that students can easily digest and reference later. The academy also includes many videos on non-math topics like biology, history, and the economics of a cupcake factory. Khan Academy videos are viewed more than 70,000 times per day – that’s more students than most major universities. Check out an example of Khan’s work below, along with a review of the his academy from PBS’s News Hour. Efforts of extraordinary individuals like Khan could revolutionize the way we teach, replacing textbooks and typical lectures with free online tutorials that students can watch at their own pace.
Education may be moving out of the classroom. According to the US Department of Education, more than 1.5 million children were home-schooled in the US in 2007. Similar trends exist around the world, and there’s an even larger group of students in developing nations that lack teachers and textbooks, but may be able to access the internet (sometimes through mobile devices). In this environment, projects like the Khan Academy may be ready to thrive. They take little capital to create (Khan has made the videos on his own, and with simple graphic tools), they are widely accessible, and they can cover a wide range of topics that students need to learn. From a small investment comes a huge impact. That sort of success has attracted a lot of attention, from philanthropists like Bill Gates to media like PBS. Here’s the News Hour’s review of the Khan Academy:

The Khan Academy is a not-for-profit business but it has started to experiment with generating some revenue so that Khan can expand the topics he covers and the detail in which he covers them. You can donate to the academy through the YouTube channel, you can purchase videos for download (for $1), and there are ads on some videos. According to CNN, Khan has also received major donations ($100k) from individual donors who wish to support his work. He’s been able to give himself a salary, produces a few videos every day, and may be receiving a chance to expand his work with the help of Bill Gates.
Clearly, videos are no substitute for having a living human being with whom you can interact with in realtime. We are likely to always need teachers (though they need not be human) who can respond to questions and direct conversations as student’s require. Textbooks, however, are another thing altogether. In the US, schools spend hundreds of dollars on books for each child. Books that are static, heavy, and limited in point of view. Imagine a future where instead of books we give students laptops and let them access a growing library of video lessons online. Non-profit organizations like the Khan academy could create these lessons online for free, or we could pay for more advanced tutorials that have interactive features and tests. Either way, students would be able to review information at their own speed and compare lessons across multiple online academies to find the approach that suits them best.
The Khan Academy isn’t the only not-for-profit education provider in the world, Khan himself works with other groups, like CK12, to create his lessons. No, the Khan Academy is just an extreme example of one man revolutionizing education. In the future, we’ll want to expand and generalize Khan’s approach to create a larger paradigm of on-demand education. Not just for younger students, but for anyone who wants to learn. (Projects like Gapminder, which we’ve covered before, work to educate adults on important global data.) I’m certainly looking forward to browsing through the Khan Academy and brushing up on my cupcake economics.

50 things that are being killed by the internet

The web is changing the way we work, play and think 

Below we have compiled - in no particular order - 50 things that are in the process of being killed off by the web, from products and business models to life experiences and habits. We've also thrown in a few things that have suffered the hands of other modern networking gadgets, specifically mobile phones and GPS systems.

Do you agree with our selections? What other examples can you think of? Please post your comments on the bottom of the story – we hope include the best suggestions in a fuller list.

1) The art of polite disagreement
While the inane spats of YouTube commencers may not be representative, the internet has certainly sharpened the tone of debate. The most raucous sections of the blogworld seem incapable of accepting sincerely held differences of opinion; all opponents must have "agendas". 


2) Fear that you are the only person unmoved by a celebrity's death Twitter has become a clearing-house for jokes about dead famous people. Tasteless, but an antidote to the "fans in mourning" mawkishness that otherwise predominates.

3) Listening to an album all the way through
The single is one of the unlikely beneficiaries of the internet – a development which can be looked at in two ways. There's no longer any need to endure eight tracks of filler for a couple of decent tunes, but will "album albums" like Radiohead's Amnesiac get the widespread hearing they deserve?


4) Sarah Palin
Her train wreck interviews with NBC's Katie Couric were watched and re-watched millions of times on the internet, cementing the Republican vice-presidential candidate's reputation as a politician out of her depth. Palin's uncomfortable relationship with the web continues; she has threatened to sue bloggers who republish rumours about the state of her marriage.


5) Punctuality
Before mobile phones, people actually had to keep their appointments and turn up to the pub on time. Texting friends to warn them of your tardiness five minutes before you are due to meet has become one of throwaway rudenesses of the connected age.


6) Ceefax/Teletext
All sports fans of a certain age can tell you their favourite Ceefax pages (p341 for Test match scores, p312 for football transfer gossip), but the service's clunking graphics and four-paragraph articles have dated badly. ITV announced earlier this year that it was planning to pull Teletext, its version.


7) Adolescent nerves at first porn purchase
The ubiquity of free, hard-core pornography on the web has put an end to one of the most dreaded rights rites of passage for teenage boys – buying dirty magazines. Why tremble in the WHSmiths queue when you can download mountains of filth for free in your bedroom? The trend also threatens the future of "porn in the woods" – the grotty pages of Razzle and Penthouse that scatter the fringes of provincial towns and villages.


8) Telephone directories
You can find Fly Fishing by J R Hartley on Amazon.


9) The myth of cat intelligence
The proudest household pets are now the illiterate butts of caption-based jokes. Icanhasreputashunba ck?


10) Watches
Scrabbling around in your pocket to dig out a phone may not be as elegant as glancing at a watch, but it saves splashing out on two gadgets.


11) Music stores
In a world where people don't want to pay anything for music, charging them £16.99 for 12 songs in a flimsy plastic case is no business model.


12) Letter writing/pen pals
Email is quicker, cheaper and more convenient; receiving a handwritten letter from a friend has become a rare, even nostalgic, pleasure. As a result, formal valedictions like "Yours faithfully" are being replaced by "Best" and "Thanks".


13) Memory
When almost any fact, no matter how obscure, can be dug up within seconds through Google and Wikipedia, there is less value attached to the "mere" storage and retrieval of knowledge. What becomes important is how you use it – the internet age rewards creativity.


14) Dead time
When was the last time you spent an hour mulling the world out a window, or rereading a favourite book? The internet's draw on our attention is relentless and increasingly difficult to resist.


15) Photo albums and slide shows
Facebook, Flickr and printing sites like Snapfish are how we share our photos. Earlier this year Kodak announced that it was discontinuing its Kodachrome slide film because of lack of demand.


16) Hoaxes and conspiracy theories
The internet is often dismissed as awash with cranks, but it has proved far more potent at debunking conspiracy theories than perpetuating them. The excellent Snopes.com continues to deliver the final, sober, word on urban legends.


17) Watching television together
On-demand television, from the iPlayer in Britain to Hulu in the US, allows relatives and colleagues to watch the same programmes at different times, undermining what had been one of the medium's most attractive cultural appeals – the shared experience. Appointment- to-view television, if it exists at all, seems confined to sport and live reality shows.


18) Authoritative reference works
We still crave reliable information, but generally aren't willing to pay for it.


19) The Innovations catalogue
Preposterous as its household gadgets may have been, the Innovations catalogue was always a diverting read. The magazine ceased printing in 2003, and its web presence is depressingly bland.


20) Order forms in the back pages of books
Amazon's "Customers who bought this item also bought..." service seems the closest web equivalent.


21) Delayed knowledge of sporting results
When was the last time you bought a newspaper to find out who won the match, rather than for comment and analysis? There's no need to fall silent for James Alexander Gordon on the way home from the game when everyone in the car has an iPhone.


22) Enforceable copyright
The record companies, film studios and news agencies are fighting back, but can the floodgates ever be closed?


23) Reading telegrams at weddings
Quoting from a wad of email printouts doesn't have the same magic.


24) Dogging
Websites may have helped spread the word about dogging, but the internet offers a myriad of more convenient ways to organise no-strings sex with strangers. None of these involve spending the evening in lay-by near Aylesbury.


25) Aren't they dead? Aren't they gay?
Wikipedia allows us to confirm or disprove almost any celebrity rumour instantly. Only at festivals with no Wi-Fi signals can the gullible be tricked into believing that David Hasselhoff has passed away.


26) Holiday news ignorance
Glancing at the front pages after landing back at Heathrow used to be a thrilling experience – had anyone died? Was the government still standing? Now it takes a stern soul to resist the temptation to check the headlines at least once while you're away.


27) Knowing telephone numbers off by heart
After typing the digits into your contacts book, you need never look at them again.


28) Respect for doctors and other professionals
The proliferation of health websites has undermined the status of GPs, whose diagnoses are now challenged by patients armed with printouts.


29) The mystery of foreign languages
Sites like Babelfish offer instant, good-enough translations of dozens of languages – but kill their beauty and rhythm.


30) Geographical knowledge
With GPS systems spreading from cars to smartphones, knowing the way from A to B is a less prized skill. Just ask the London taxi drivers who spent years learning The Knowledge but are now undercut by minicabs.


31) Privacy
We may attack governments for the spread of surveillance culture, but users of social media websites make more information about themselves available than Big Brother could ever hoped to obtain by covert means.


32) Chuck Norris's reputation
The absurdly heroic boasts on Chuck Norris Facts may be affectionate, but will anyone take him seriously again?


33) Pencil cricket
An old-fashioned schoolboy diversion swept away by the Stick Cricket behemoth


34) Mainstream media
The Seattle Post-Intelligencer and Rocky Mountain News in the US have already folded, and the UK's Observer may follow. Free news and the migration of advertising to the web threaten the basic business models of almost all media organisations.


35) Concentration
What with tabbing between Gmail, Twitter, Facebook and Google News, it's a wonder anyone gets their work done. A disturbing trend captured by the wonderful XKCD webcomic.


36) Mr Alifi's dignity
Twenty years ago, if you were a Sudanese man who was forced to marry a goat after having sex with it, you'd take solace that news of your shame would be unlikely to spread beyond the neighbouring villages. Unfortunately for Mr Alifi, his indiscretion came in the digital age – and became one of the first viral news stories.


37) Personal reinvention
How can you forge a new identity at university when your Facebook is plastered with photos of the "old" you?


38) Viktor Yanukovych
The Orange Revolution in Ukraine was organised by a cabal of students and young activists who exploited the power of the web to mobilise resistance against the old regime, and sweep Viktor Yushchenko to power.


39) The insurance ring-round
Their adverts may grate, but insurance comparison websites have killed one of the most tedious annual chores


40) Undiscovered artists
Posting paintings to deviantART and Flickr – or poems to writebuzz – could not be easier. So now the garret-dwellers have no excuses.


41) The usefulness of reference pages at the front of diaries
If anyone still digs out their diaries to check what time zone Lisbon is in, or how many litres there are to a gallon, we don't know them.


42) The nervous thrill of the reunion
You've spent the past five years tracking their weight-gain on Facebook, so meeting up with your first love doesn't pack the emotional punch it once did.


43) Solitaire
The original computer timewaster has been superseded by the more alluring temptations of the web. Ditto Minesweeper.


44) Trust in Nigerian businessmen and princes
Some gift horses should have their mouths very closely inspected.


45) Prostitute calling cards/ kerb crawling
Sex can be marketed more cheaply, safely and efficiently on the web than the street corner.


46) Staggered product/film releases
Companies are becoming increasingly draconian in their anti-piracy measure, but are finally beginning to appreciate that forcing British consumers to wait six months to hand over their money is not a smart business plan.


47) Footnotes Made superfluous by the link, although Wikipedia is fighting a brave rearguard action.

48) Grand National trips to the bookmaker
Having a little flutter is much more fun when you don't have to wade though a shop of drunks and ne'er-do-wells


49) Fanzines
Blogs and fansites offer greater freedom and community interaction than paper fanzines, and can be read by many more people.


50) Your lunchbreak
Did you leave your desk today? Or snaffle a sandwich while sending a few personal emails and checking the price of a week in Istanbul?
