Through a browser like MIT's iCampus XTutor or custom made backend server interp/compiler with browser access http://icampustutor.csail.mit.edu/6.001-public/ http://icampustutor.csail.mit.edu/6.001-public/ I had the crazy idea once that since Facebook's Internet.org was available in developing countries I could create a simple curriculum by finding freely distributable teaching material and make it into a phone based course where you could learn both math and how to script your own device, instantly test your answers like edx/XTutor, analyze other apps or modify other apps behavior ect by practicing with an interpreter running on your phone using lambda native. I never got around to trying it but if the free tier for Internet.org lets you run javascript on any facebook page you could create 'Facebook Technical Insitutute' by calling out to a server like XTutor to return results (which is likely blocked for free tier access) or just using a basic interpreter (lambdanative.org) on the device. You would also probably need to write your own in app keyboard to make typing (),#,',[],/ ect easier or buy an external keyboard. Other than my insane idea of FB school I've never tried to be productive on a phone beyond ssh into a remote server to fix something.
