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."'"
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.

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.
No, online education is just 'education'. We have been having this argument for at least 100 years regarding technology and its transformation of learning. Some things do get easier better with technology, but in the end what we have a is a teaching and learning problem -- not a technology problem. Using new technologies we figure out ways to improve teaching and learning but one technology will not be the answer.
Nor will Salman Khan's idea that he is going to build Charter schools where students watch and hour of his videos a day to learn all the math they need to know and spend the rest of the day playing guitar or making paintings.
Learning is hard. Some parts can be made easier with computer technology. Some parts can be made easier by turning them into a game. Some parts you just need to sit down and memorize. Most parts are done best when there is a group who are trying to figure things out and working together to achieve a common goal.
This is how businesses grow and get better. This is how children grow and learn. Technologies including chalk, pencils, iPads and times tables are tools to help.
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.
I'd have given a testicle for something like Khan Academy, when I was young. Instead, I got a bunch of angry overworked and under-performing teachers that just wanted me to shut up, go away, not ask questions, and *most of all* never correct them when they spread completely inaccurate information to the class. All I wanted was a way to self-educate. To a degree, I accomplished that with a lot of school-skipping, when I spent day after day at the central public library, instead. However, I was often hindered by wanting to learn things, but not knowing where to start or what path to follow. For example, I would be far ahead of where I am, today, if I had someone or something to guide me into programming a decade earlier. Back when I didn't have an internet to tell me about C and C++ and Perl. Back when the furthest I could get was "I know I want to code" and reading a book in the tiny section at the library that only really had theoretical things with pseudo-code that didn't mean anything to me at the time.
Khan (and the internet, overall) is an autodidacts wet-dream. It is what could have changed the lives of so many young people in the past who weren't stupid or lazy, but weren't getting any real meat out of their "real" education.
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.
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.
