Khan Academy critique addresses some myths about math learning.

Thanks for sharing this posting; I've been saying essentially the same thing ever since I first saw the KA videos, and especially after it became the next big thing to save math education. There are certainly pragmatic advantages to students having access to concise, reasonably clear video explanations of discrete math topics and procedures (they can stop and start them whenever they want, view them multiple times, etc.), but they definitely function within (and reinforce) the dominant paradigm of what math is and what it means to learn math. KA is designed to help students survive in the current status quo rather than attempting to change that status quo in any significant way (and presumably it does help some students, although I haven't seen any evidence on that point). Where it might be able to play a role in changing current practice is if teachers were to use it, or other resources like it, to "invert" the traditional model so that students are using online resources like KA outside of class for the procedural skills and teachers are using class time to focus on deeper conceptual understanding through a variety of approaches including collaborative group work...

I definitely agree with the premise of the article, but I do not agree with the statements made towards Khan Academy or other multimedia instruction. Is the current curriculum too focused on procedures, algorithms, and rote memorization? Of course! Is direct instruction incredibly overused (with loads of research pointing towards a student-centered learning environment)? Yep. But the problem has nothing to do with Khan or multimedia. I don't see the sense in tearing down innovations in math education. My opinion is that the lack of innovation is exactly the problem with our curriculum and pedagogy. In a more perfect world, where math curriculum is as deep as it is wide, procedures, skills, and memorization will still have a role (albeit, a much smaller role). Multimedia can relieve instructors the "necessity" of offering in-class models of these algorithms and skills. In fact, with videos, students can be offered many alternative methods and algorithms. Allowing them choice. I see multimedia as a way of reengaging students in their own math education. We currently offer students the resource of a textbook that (usually) offers only one method of solving, using language almost indistinguishable to students. Math instructors realize this issue and see it their job to offer better explanations and examples. My point is this: If an instructor was aware that several superb, clear videos were available to students on a certain algorithm, what would that instructor be compelled to discuss during class time? I would hope they wouldn't bore students with another 50mins+ of the same thing, but instead use their time together to engage students in real discussions and activities focused on the students' conceptions and the underlying mathematics in the procedures.
