Khan Academy: the Teachers Strike Back
theodp writes "With his Khan Academy: The Hype and the Reality screed in the Washington Post, Mathalicious founder Karim Kai Ani — a former middle school teacher and math coach — throws some cold water on the Summer of Khan Love hippies, starting with U.S. Secretary of Education Arne Duncan. From the article: 'When asked why so many teachers have such adverse reactions to Khan Academy, Khan suggests it's because they're jealous. "It'd piss me off, too, if I had been teaching for 30 years and suddenly this ex-hedge-fund guy is hailed as the world's teacher." Of course, teachers aren't "pissed off" because Sal Khan is the world's teacher. They're concerned that he's a bad teacher who people think is great; that the guy who's delivered over 170 million lessons to students around the world openly brags about being unprepared and considers the precise explanation of mathematical concepts to be mere "nitpicking." Experienced educators are concerned that when bad teaching happens in the classroom, it's a crisis; but that when it happens on YouTube, it's a "revolution."'"
Online education is in its infancy. This is an area where many ideas are being tried. Some will work better than others. Probably nothing currently available is "the answer", but rather all are those little baby steps toward what will eventually emerge. It's a normal and pretty universally unavoidable process.
WALSTIB!
Yeah, because holy shit that teacher pay rate is out of control.
Seriously, since when did the abysmally low rate of pay teachers receive become a point of contention?
If the teaching is going to be bad either way, then Kahn costs a heck of a lot less to get the same result.
If Kahn and a unionized teacher are both bad, for Kahn the solution is for someone to upload a new lesson that's better. For the teacher, the solution is to suck it up because teacher unions demand that seniority trumps all other considerations.
I have no idea if Kahn or classroom teachers are ultimately the better choice. But the teachers unions better cobble together some damn good arguments for why they deserve the compensation and job protections they get, if Kahn offers way better bang for the buck.
My personal thought is, who cares? You get what you pay for, right? Services like Khan Academy are great if they're helping people learn things they wouldn't otherwise take an interest in learning about, or if it enables learning they were interested in but couldn't afford traditional methods of education.
If you're already IN a traditional classroom environment, then no - I'm not sure Khan Academy lessons are so great. I mean, you have to ask, as a paying student, why you're paying your hard-earned money to get a personal classroom experience with supposed educational professionals, who turn around and ask you to sit through canned Khan presentations instead of presenting the material themselves.
As for the "precise explanation of mathematical concepts to be mere nitpicking"? Maybe it is, really? By that, I mean, most people are really only interested in learning math as long as it allows them to accomplish something. The minority who find the theory itself fascinating and want to learn more math for the sake of learning it are the ones who will probably move beyond whatever Khan Academy teaches, and consult other sources.
If you know enough math to get correct answers to the problem you encounter as part of your daily life or job, then that's likely ALL the math you really need to know.
This is article deriding free on-line math education written by a person who develops paid on-line math education.
Eagles may soar, but weasels don't get sucked into jet engines.
If the complaint about how "rise of run isn't a formal definition of slope" is indicative of the kinds of errors in his lectures, then I'd say Khan is right that the naysayers are just being picky. Yah, it's not perfectly accurate or a formal definition, but it's an excellent start to understanding a deeper understanding.
An educators job should be to get people excited about a subject, not to present the most perfect, gods honest truth answers to everything. Anyone interested in a subject will go on to learn more, and find out the more nuanced and correct answers. If you've ever become an expert in any field, you know that everyone (including the best teachers) don't always have time or knowledge to give the best possible answers. That's OK, since education doesn't stop once the class stops.
If your ultimate (and final) response when asked why you believe something is "because my teacher told me", then you really don't understand the subject matter very well at all.

If the teaching is going to be bad either way, then Kahn [sic] costs a heck of a lot less to get the same result.
I think I should point out that I haven't found any place where Khan suggests that his youtube videos replace public education.
Khan's made a few mistakes. The first that is the worst is that the article mentions he was corrected about multiplying negative numbers and instead of praising the people for making a new video correcting him, he apparently just took his video down and replaced it. And then made some little remark about why people put up such a big fuss about this concept. His second and less grievous mistake was to engage talking heads and accept praise from politicians. I think if he had just focused on making videos, ignored the praise and let Bill Gates or some other public figure pitch the video, he wouldn't find himself the target in this back and forth. We need to stop looking at online education as a replacement and instead as an augmenting force in our children's learning.
My work here is dung.
yep... because they all put in carbonite for those two months off and don't have to eat...right?
Khan Academy is the greatest supplemental education resource I have ever seen. But, one thing it can't do is force you to sit down, block off an hour a day, and learn a subject. Let's face is, 95% of us do not have that motivation, especially where one tab away awaits an entire internet of distractions.
Having a physical obligation, to an in-face person in a physical location to show up and learn something is an exceptionally powerful psychological motivational force and something that online education simply can't replace.
But man, would have I killed to have Khan available when it came to exam time in high school and college.
But bad teachers who have been around forever are very highly paid. Good teachers that have not been there for 20 years are the under paid ones. And that is the problem.
There is so much of accessible math theory locked behind the wall of algebra. Mathematics is BORING until you can show people WHY they are learning this. Most math classes i have taken are just total wrote calculation with no rhyme or reason. Its 'do it this way, you'll figure why out later'. When the 'later' is 2 years of math classes down the road, Khan's kinda got a point.
Good-bye
We need to be wary of Kahn Academy, but we have to be wary of "experts" that are condemning Kahn Academy as well.
A lot of times the "experts" doing on the complaining in popular media are just as worthless as listening to your fat neighbor who is bitching over his beer on his porch. Most of the talking heads on TV are like this and more and more even the people that are high ranking in governmental and professional organizations are well is well. It's because they're better at bullshit then their "expert" subject.
So.. as far as Kahn Academy, it's likely a little bit of both sides are right and both sides are wrong. You have "educators" that don't want to absorb different ideas and you have Kahn who is also a bit of an ass himself.
Look at this like Wikipedia. There are obvious quality problems, but Wikipedia keeps improving and getting larger, and if you're Microsoft Encarta, there's just no market for you any longer (thus, the first MS product actually killed by Open Source).
The guild apprenticeship system really hated book-learning. Copyists really hated printing. Both of these were previous means to commoditize education. This is just more of the same.
There will be tremendous economic repercussions from the further commoditization of education.

Bullshit. Ever seen the requirements to stay certified as a teachers? 9, sometimes 12 hours of study per year that they have to shell out and attend for college courses just to "stay certified." It's a small wonder most of them eventually get multiple Masters degrees or a Doctorate, there's no point in not for the amount of "continuing education" courses they are required to take just to stay employed.
And when do you think they're taking those courses, hmmm?
I hate right wing shitbag morons like you who misrepresent teachers and think they're "doing nothing" all summer.
Wrong. Classroom PLUS Khan
Yes, and there are examples that the Classroom + Khan is an effective model. The Economist has an article describing how the Los Altos school district is using Khan's videos to provide the "dry lecture" which is assigned for homework while classroom time is used for supervised problem solving with the teacher roving about helping any struggling students. That model makes complete sense to me especially since we keep hearing stories about how parent's can't do their kids homework (I've been called in to help my little cousin with her math homework at times when her parents were thoroughly confused).
I'm hoping you're being sarcastic and don't really have the idea that there are just all these "real" professional-wage paying jobs that are available for just three months that are being held open for teachers.
Who would rather have teach you physics, someone with a degree in Education or someone with a degree in Physics?
I'm going with "sarcastic".
You are welcome on my lawn.
So if there aren't any fires, firefighters shouldn't be paid? And if there aren't any crimes, police shouldn't be paid?
Wow, are you off-base. You don't really know anything about it do you?
...and still be elected governor of New Jersey?
You're getting all your information about teachers and teaching from talk radio, aren't you? That statement is not true, even here in Chicago, which is ground zero for the "thugs in the teachers' union.
You are welcome on my lawn.
When will America wake up and realize that just one good teacher is worth more than both the Koch brothers
Maybe voters will be willing to pay good teachers more when we stop paying bad teachers the exact same salaries.
Or when we stop spending more money on administration and pointless toys like "Smart Boards" than on teachers.
In contrast, my mother has taught high school french, italian, and spanish for at least a decade now. Her workload is insane. Not only does she have the normal hours of the day where she has to be on campus directly dealing with kids, she then gets to spend time reading and grading papers, as well as evaluate how well her lesson plans worked, and update them for the next time she teaches (or to adjust for faster/slower class progress). The net result is that she works at least twelve hours a day, often more, and regularly gets about four hours of sleep.
If you're teaching a class that requires grading of papers or has handouts. you get to create the material, make enough copies, teach it in class, read/grade all of the responses, and then repeat. God help you if you want to actually challenge your students with more than multiple choice, and have them write real sentences or prose. 30 students times 5 classes is 150 students' worth of papers to READ every day. How long would you spend on each? My teachers in high school, like my mother now, read their students' papers closely enough to be able to write corrections, and even write feedback on them. I imagine it's more than a minute per student spent correcting, and more than ten minutes spent per class evaluating the effectiveness of your curriculum and planning how best to ensure your students actually _learn_. So, that's another four hours on top of your "eight hour" day right there.
So, while teachers bring in some decent sounding dough, the amount of time they put into it depends a lot on the subject matter they teach and the degree to which they invest themselves in teaching well. (It's probably still a lot easier than being a sysadmin, though.)
