live-editor

It seems to me that Scrimba is just an spin-off from Khanacademy's live-editor on steroids. I would not actually called it innovation per se, but pretty useful btw! Along with repl.it, best tools avalaible so far. [1]: https://github.com/Khan/live-editor

We've open-sourced several other mostly-KA-specific parts of the site, including these: https://github.com/Khan/khan-exercises https://github.com/Khan/perseus https://github.com/Khan/live-editor Contributions are few and far between; good contributions are even more so. It hasn't been worth the time investment, unfortunately.

The recording part is there as well, in particular https://github.com/Khan/live-editor/blob/master/js/ui/record... These slides give a little high level overview of that: https://speakerdeck.com/pamelafox/teaching-programming-onlin... (slide 26)

Thanks! That environment is all open source, if you're ever looking for some OSS bugs to tackle :-) https://github.com/Khan/live-editor

Pamela from KA here. We're using the same client-side SQL solution as sqlteaching.com (which is great!). Our editing environment is here and open source: https://github.com/Khan/live-editor KA does have classroom tools and progress reports, but we don't have the ability for teachers to create their own lessons (if that's what you're looking for). More details on that here: https://www.khanacademy.org/coach-res/reference-for-coaches/... It's a lot of work to create the classroom management itself (that's done by a whole separate team at KA) so it's not something most folks tack on to teaching sites.

Yeah! We have full curriculum around it, as well (Intro to JavaScript, Game development, and Natural Simulations): https://www.khanacademy.org/computing/computer-programming It uses a real-time JavaScript editing framework that we're in the process of open sourcing: https://github.com/Khan/live-editor A technical talk on the editor (a bit dated at this point, but most of the points still hold) can be found here: http://ejohn.org/blog/talk-khan-academy-computer-science/

Very cool, reminds me of the interactive widget used in the Khan Academy CS program [1]. I believe John Resig [2] developed it. [1]: http://khanacademy.org/cs [2]: https://github.com/Khan/canvas-editor
