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 not reported here -- see the update at the bottom of the story

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 been done on our site and 2 million more are done each day

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 completed) an HCI-like program[1] or have relevant real-world exper

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 OOCSS and only see the "this is how you write proper CSS" and do

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 different approach to the purpose of CSS. Once you make the men

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 quickly. Automatic recall has also been correlated with underst

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 here that suggests systematic misleading (if not out-right defr

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 product and the content better. In addition, we are looking for mo

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_considered_harmf... and here: http://www.jnd.org/dn.mss/hcd

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 attributes. When the lines between personas are hard to dra

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 visit the Genius Bar with their iPhones at all. I am guessing t

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 actually worth reading the thesis as it's pretty interesting stu

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, and exercises that is usable on smaller screens because, altho

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 gladly stopped worrying about the particulars there as we'v

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 teachers, students, administrators, and parents to help us make

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 pretty well for finding good stuff. When you are on the move,

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 is a challenge. For example, not everyone is as knowledgeab

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 going to have to cut a lot more than 16% of the staff.

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". My opinion of the president is informed by my knowledge of t

The Khan Academy is not seeking to replace teachers/coaches/tutors. The good ones will take advantage of what resources like the KA have to offer. On the other hand, a bad teacher has the ability to damage a student's ability and desire to

Kiln gets you a pretty cool (if I do say so myself) code review system, an all-new web interface for managing your code and repositories, tight integration with FogBugz, and support from Fog Creek. If you don't need those things, then by al
