Can Anyone Catch Khan Academy? 190
waderoush writes "Even as name-brand universities like MIT and Harvard rush to put more courses on the Web, they're vying with an explosion of new online learning resources like Coursera, Udacity, Udemy, Dabble, Skillshare, and, of course, Khan Academy. With 3,200 videos on YouTube and 4 million unique visitors a month, Sal Khan's increasingly entertaining creation is the competitor that traditional universities need to beat if they want to have a role in inspiring the next generation of leaders and thinkers. Lately Khan's organization has been snapping up some of YouTube's most creative educational-video producers, including 'Doodling in Math Class' creator Vi Hart and Smarthistory founders Beth Harris and Steven Zucker. Universities are investing millions in software for 'massive online open courses' or MOOCs, but unless they can figure out how to make their material fun as well as instructive, Khan may have an insurmountable lead."
The Chronicle of Higher Education has a related article about the above-mentioned Coursera, and how they plan to make money off of free courses. A contract the company signed with the University of Michigan suggests they aren't quite sure yet.

missing the point entirely (Score:5, Insightful)
There have been good textbooks for centuries. Watching a video is not going to improve things much. Online quizzes don't make people brilliant.
The first reason the top universities are at the top is their research output.
And the reason undergraduates excel at those top universities is that they spend almost every day for several years in contact with the people and resources which make that research possible. They go to tutorials. They chat through problems. They do extended lab work. They write extended pieces of work which are marked carefully by experts who can provide interactive feedback.
The Open University, the pioneering distance education factility in the UK which has several hundred thousand part-time and FTE students, has since 1969 provided more than all these supposedly "new" online education providers: custom textbooks tailored for learning with worked problems; a tutor who will mark your work and who you can contact whenever you want when you have a problem; several face-to-face tutorials throughout the year; possibly one or more residential schools; etc. Exams are all done in exam centres under exam conditions. Even then, it cannot hope to match the best red brick universities.
Khan knows how to market itself. It gives an opportunity to those dilettantes who don't know where else to find the information, online or offline. But it won't produce a new generation of leaders / top thinkers.

I'm sick of that presumption. The point of education SHOULD be to become educated. Then, you use that education to do X work better than others without that education.
Instead, we treat it like a membership card into business. I fail to understand why so many MBAs hate unions when they refuse to hire someone without an MBA, thus creating their own union.

Which has been true since before recorded history. Education has always involved paying a tutor or lecturer to teach the younger generation, and thus the tutors were actually businessmen selling a service.
Khan Academy criticisms (Score:5, Insightful)
Khan Academy is a great resource, but it's far from a perfect substitute if one want to accomplish deep learning. The fact is that there is a LOT of free and very helpful tutorial learning material on the Internet. Khan has caught a lot of interest because of the sheer scale that Sal Khan accomplished on his own. I think it's a great tool, but is becoming quite overrated in terms of what we know from those who teach face-to-face, and learning science.
Here are some valid criticisms of Khan Academy. http://chronicle.com/blognetwork/castingoutnines/2012/07/03/the-trouble-with-khan-academy/?cid=wc&utm_source=wc&utm_medium=en [chronicle.com]

In sum, Khan Academy is NOT a revolution in learning; it's a tool that many will use to help revolutionize education.
Different Audience (Score:3, Insightful)
Khan Academy targets a wider audience than the others that are mentioned. Most of the others are aimed at university level education. For example, Coursera is mostly undergraduate courses like Algorithms and Cryptology. Udacity has some machine learning car. A lot of these are also tech based and/or programming based.
Meanwhile, Khan Academy offers everything from elementary Algebra and Geometry to Calculus and Differential Equations. So they reach the whole k-12 audience which the others will not reach. That isn't necessarily a bad thing, it's just a different product. I hope they don't water down Coursera because it's good at what it does: free undergraduate level courses. I don't want it to spend time doing 8th grade Geometry, Khan does that already!

Accreditation and degrees carry weight because of what they mean. What does it mean if you say that you watched a few hundred YouTube videos and have the video history to back it up? Yes, you may have learned a lot from them, but how would anyone be able to tell that? Should they trust your word over the piece of paper another applicant has that says a recognized and trusted organization certifies that he learned that material?
Yes, it's a membership card, but it's a necessary one. In an ideal world, employers would be able to recognize skill, regardless of whether there's a piece of paper in the applicant's hand. We're not in an ideal world, however. Even if there were a perfect and not-too-burdensome way for employers to test the skills of applicants, most competent employers are willing to accept an otherwise-excellent applicant who is a bit rusty on some topics, since they understand that the applicant's prior experience and skills will allow them to pick it up again quickly. You can't test for that easily, and on the surface it doesn't look much different from not knowing the material at all. A degree is a decent indication that the person's claim to have learned the material is true. A YouTube video history is not.
That said, if there were someone with prior work experience (i.e. the other form of membership card) who hadn't gone through a university, I don't see why that would be problematic at all. But hiring someone on the basis of their claim that they learned the material from a series of videos? I don't doubt that people have done it, but it seems to me like a rather large risk, or else an expensive process to go through to test the veracity of their claims. Especially so in programming and the like, where a student who goes uncorrected in their bad habits is likely to have developed poor practices that will be difficult to correct.

Oh yes it does. A conversational description of the material, as opposed to over-edited reference-worthy technical descriptions, can go a very long way in helping understanding. Seeing the interaction of somebody actually working through a problem and pointing things out (including their thought process), instead of a terse list of opaque steps, is huge. Along with the slides and downloads, all the reference material is still represented, but watching another human demonstrate the information is much often a faster and deeper way to communicate the same concepts. Not everybody can learn as well from just reading textbooks, even the good ones. Even if they can, going through a video lecture before reading the text seems to be a great way to make the reading far more meaningful, as familiarity has been bootstrapped.
There is merit to the other facets you describe, but lowering the cost and other barriers to entry to actual training (not just reference materials) is an amazing step forward.

Anyone? No. Someone? Probability would say "yes".

What a load of crap. I love Khan's materials, but not because they are fun, but because they are valuable. Plus, I had plenty of college professors that made their lectures fun. And I had classes that were some of the most imporant in my education, and I know the subject and delivery weren't fun. Fun is not an intrinsic property of good education.
Edutainment != education. Such is the state of our sorry ZOMG-Kardashian society.
Also there is pretention in the quoted text that colleges are having a hard time producing instructive online material. Seriously, have they never seen a Stanford/MIT online lecture? There are many universities out there providing grad-level education online with success.
Another thing that people misconstrue (and not a criticism of Khan's videos, but of the fanboys who do) is that Khan's videos are nice to watch because... gasp, they are, in general, relatively shorter than a full-blown lecture. A 90-minute long video lecture will bore you down no matter how "fun" the instructor is. Specially if the material is dense. Or try a 3 hour video lecture. You'll be crawling off the walls even if it is performed by your favorite professor (I know because I've had to take those lectures @ WPI.)
1. If Google were to decide to put its might behind Udacity (which is really fine material btw), wouldn't anyone think that it would pass over Khan Academy? Ergo, the title of this story is an oxymoron like no other.
2. Universities will adapt, prices will go down. They won't get replaced by them, in particular when it comes to research. What I see here is that these private enterprises will accelerate adoption of online media by brick-n-mortar schools (which has been occuring since before Khan came into the picture.)
This is not to take anything away from Khan's marvelous work. But for Christ' sake, don't treat it like the second coming holding the holy grail while riding a silver bullet.

Khan grows daily, and it quite capable of teaching high levels, even above the doctorate level.
Khan is a scattering of disparate modules, and quality varies.
It needs to be structured so that it can be learned standard courses in each discipline, on a term by term and year by year basis - albeit in far less time.
It also needs lab courses - youtube does fill the lab need, but not as well as a true lab, where fluids are poured and voltages measured and lab reports written and graded.
I can see a time where there is computer grading, with a secure ID, tied to IP address to give certificates of some kind. Machine certificates done by remote are still susceptible to hired ringers writing exams for people (which plagues real colleges too), the real world will demand real invigilated exams for each course before a complete course can be graded as passed and an aggregate of course completed as a year passed and three/four years = a degree. Once this is done, the entire degree will be able to compete in the hiring process.
I can see a process of maturation in the idea, but the idea of invigilated exams added to Khan will take a way to pay for this, since it goes beyond volunteer work (IMHO).
Five years from now, we will be amazed at how far they have come. I wonder if the brick and mortar colleges will try to kill the idea???

Kudos to you for taking the time to properly interview candidates.
I don't disagree with anything you said. I merely believe that most employers would be unwilling to spend so much time interviewing candidates who likely have a lower chance of being prepared for the challenges posed by the job. For every excellent applicant that taught themselves via an alternative method, you'll have dozens of slackers who claim to have done so but have not. And while I agree entirely regarding your assessment of college, at least it establishes something. You'll still have a disproportionate number of slackers, but the number should be lower, given that college at least imposes some requirements, whereas self-study does not.
As I said in my original comment, I do believe that if someone has prior work experience then it shouldn't matter where they got their skills. At that point, as you said, you can judge them on the basis of their prior work, but if they lack prior work experience, then I see no problems with an employer using the degree as a filter on their candidate pool. It's not perfect, but it does help to remove the part of the pool that is less likely to have the necessary skills.

Which in practice never actually happens. Sure, if you've just gotten laid off, continuing ed classes might be a way to become employable again, but for the most part, while you're working, you're working. You aren't going back to school constantly, and apart from the things you have to learn to keep your job, you're probably not taking classes on the side to make yourself a better candidate for a position at another company. This means that you're less mobile, and therefore are likely to get paid less for working longer hours, because they know they don't have to pay you more money to retain you as an employee.

Text versus video? Irrelevant. The core problem with education is that either the teachers are not up to the standard, or the books are poorly written. And what is Khans academy doing? They are doing videos, but that is irrelevant in itself, what they are actually doing is to do a proper job at TEACHING their material, in contrast to many sources.
If you have a problem with Khan being video, then why don't you have a problem with subpar teaching in general?
