The Khan Academy is not the future of education. Don't get me wrong, I think they're doing a superb job and I'd encourage people to contribute to their efforts. Khan is obviously a great presenter with a remarkable ability to explain complex concepts using a new medium. However, the future of education is closer to hacker culture than it is about new and better content delivery mechanisms. Let me explain.
First, I totally buy the argument that a YouTube video can be a better method of delivering content than a book or even, as Kahn says, a live teacher. However, learning is much more than that. Learning is about imagining, playing, creating, sharing and reflecting (Resnick 2007, PDF: http://j.mp/gqnc6f http://j.mp/gqnc6f).
To say that learning math is about watching a video and drilling on some problem set, is like saying that learning Python is about doing a tutorial and solving some exercises. Hackers know this well. You don't really learn a programming language until you build some project, especially a personally meaningful one. Creating something not only helps you learn the language but also its community, culture, practices, how to ask questions and get feedback on your work.
Think about it, would you rather hire a developer that has finished some tutorials or one that has actually hacked some projects? The same logic applies to most other fields. Artists and scientists know this as well: you learn by doing in the social context of a community.
Unfortunately, schooling has taken the "hacking" away from learning and has focused on improving content delivery, artificial problem-solving and test-taking. Often using technology. I liked when he mentioned that the teachers have more time to mentor students. However, their mentoring is most likely still focused on the artificial and decontextualized approach of traditional schooling.
Initiatives like the Khan Academy will probably play a role in the future but to really improve education the system and the approaches should change. One should look at exemplar learning environments like the hacker communities or even the Brazilian Samba schools. Settings that are "real, socially cohesive and where experts and novices are learning" (Papert 1980, Google Books: http://j.mp/dLNbGG http://j.mp/dLNbGG).
In 1971, Ivan Illich outlined an inspirational alternative educational environment where "the child grows up in a world of things, surrounded by people who serve as models for skills and values. He finds peers who challenge him to argue, to compete, to cooperate, and to understand; and if the child is lucky, he is exposed to confrontation or criticism by an experienced elder who really cares."
Illich said that the four resources learners need are "things, models, peers, and elders". In his 1971 vision, Illich said that "the operation of a peer-matching network would be simple. The user would identify himself by name and address and describe the activity for which he sought a peer. A computer would send him back the names and addresses of all those who had inserted the same description. It is amazing that such a simple utility has never been used on a broad scale for publicly valued activity"(http://j.mp/hNUVV8 http://j.mp/hNUVV8). Sounds familiar? When I read Illich, I think of HN, StackExchange, and the larger ecology of spaces that hackers have created around social learning. My hope is that these and other similar approaches scale up and get adopted more broadly along with resources like the Khan Academy, OCW and others.
- ThomPete 16y agoI think you are missing the point here. Learning math is not like learning programming. Math has a quantitative evaluation process. The kind of scenarios you are talking about both have a quantitative and a qualitative evaluation process. I.e. you can be creative in your programming and the "answers" but not so much in math. Also I don't think Kahn Academy is in any opposition to Seymore Paperts "Mindstorms". In fact you could imagine the videos being used to teach children to get started before they go on to hack together their little programs. What they have done is for the first time made a system that quantifies the learning process so that it benefits the student rather than the school. Pretty significant if you ask me.
- andresmh 16y agoI think you're right regarding Khan Academy not necessarily being in opposition to Papert's Constructionism. But I think Papert would argue that learning math is very much like learning programming. In fact, he created the Logo programming language as some sort of "mathland" where learning math would be like learning French in France ( http://www.wired.com/geekdad/2007/03/the_origins_of_/ http://www.wired.com/geekdad/2007/03/the_origins_of_/, http://j.mp/h6BiOC http://j.mp/h6BiOC) Real mathematicians have often lamented on the approach to mathematics that schools have taken. For example, this essay titled "A Mathematicians Lament" starts like this: "A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. [...] Since musicians are known to set down their ideas in the form of sheet music, these curious black dots and lines must constitute the 'language of music.' It is imperative that students become fluent in this language if they are to attain any degree of musical competence; indeed, it would be ludicrous to expect a child to sing a song or play an instrument without having a thorough grounding in music notation and theory. Playing and listening to music, let alone composing an original piece, are considered very advanced topics and are generally put off until college, and more often graduate school. As for the primary and secondary schools, their mission is to train students to use this language— to jiggle symbols around according to a fixed set of rules: 'Music class is where we take out our staff paper, our teacher puts some notes on the board, and we copy them or transpose them into a different key. We have to make sure to get the clefs and key signatures right, and our teacher is very picky about making sure we fill in our quarter-notes completely. One time we had a chromatic scale problem and I did it right, but the teacher gave me no credit because I had the stems pointing the wrong way.'" http://www.maa.org/devlin/LockhartsLament.pdf http://www.maa.org/devlin/LockhartsLament.pdf
