The data presented in this article is extremely suspect. The methodology for both the collection of shipment information and the extrapolation to revenue are secret (or at least no…

Mountain View, CA - full-time designers and mobile devs Khan Academy's mission is to provide a free world-class education for anyone anywhere. Over 1 billion math problems have bee…

Yes! KA is looking for two types of design interns: product design interns, and visual design interns. We strongly recommend that product design interns be in (or have just complet…

There is actual data to look at here: http://nces.ed.gov/pubs2009/2009030.pdf Desire to provide religious or moral instruction is at the TOP of the list of reasons people homeschoo…

I am saying that you can follow OOCSS coding practices and still wind up with a ton of really great abstracted styles that you don't reuse. That is because most people look at OOCS…

This is something I've been thinking a lot about recently, and while all of these approaches solve some problems I think the requirement for maintainable CSS is a fundamentally dif…

Loving the thoughtfulness here, and I have a few more resources I need to read now. Re: Quick and Correct badges - It is important in many cases to be able to recall math facts qui…

Simply stating it is not a ponzi scheme doesn't advance the conversation in a meaningful way in my opinion. It's really just semantics at this point. There is a lot of evidence her…

This is an ongoing falsehood. Several Khan Academy employees were real honest-to-goodness teachers, and we work with teachers directly in-person every single day to make the produc…

There is a name for this approach to design. It's called Activity-Centered Design , and Don Norman has written a bunch about it here: http://jnd.org/dn.mss/human-centered_design_co…

I find that personas are nearly useless for this kind of design discussion. Personas are an attempt to homogenize some group of people into a single pseudo-person that has specific…

What about accounting for the massive selection bias of people who would actually visit the Genius Bar in the first place and combining that with the total number of people who vis…

Working for the Khan Academy, I've seen the link to this video a bunch of times. Naturally, I was really curious about the voracity of the claims, so I did some research. It's actu…

John beat me to the punch here. We're thinking about a much more general mobile strategy. My personal mission is to try to design an experience for content, student interaction, an…

Sorry for not addressing that first time-round. We are funded by the Google and Gates Foundation grants plus private donations. As far as "most", I am not totally sure. I have very…

Actually, it was totally free in terms of the school not having to lay out any cash. The reason we chose to work with them, however, is that they committed a ton of time from teach…

More importantly, Yelp is most useful after you've already left home. There are tons of resources on the "web" for finding reviews of various local stuff, and a web search works pr…

Good point! Fixed it in the main article too. Thanks.

Totally fair criticism. Like any design effort, it represents a careful priority balancing act. The Khan Academy is trying to do a lot of things, and communicating that effectively…

The really misleading thing about these statistics is that the budget is not 100% teacher salaries. I am guessing, it's not even close. That means to get your 16% savings you are g…

I think I understand what you're trying to say here, but the comment about presidents in war time is really throwing me off. A president is an actual person who has done "things". …
