I never said I had solved it, only that I was working on solving it. Nowhere in the documentation or in my comments here I intended to give the impression this is anywhere close to done or intended for the general public at this time. There's an entire half of the project intended for instructors that I have barely mentioned publically or had had time to properly sketch out. Mathacademy is pretty much the same thing from what I can gather and has already been applied very successfully in a school district. Same thing with the DARPA tutor also mentioned here. All of the principles these tools are based on are already proven by mountains of research. And yet no free software, general solution exists that combines all of them. I know because I resisted working on this for months while looking for it. And sure, it's an interactive homework list. I say so myself in the readme. One that automatically reviews skills at variable intervals depending on the mastery of the material, interleaves questions from separate topics for increased retention, gradually introduces new topics only after dependent knowledge is sufficiently mastered, balances the difficulties of the questions, and allows students to study specific portions of the graph. So if we are giving each other advice on how we come across online, I find your comments lacking any criticism I can use to improve the project, and very dismissive of the hundreds of hours I have spent researching and working on the problem with the intention of giving all of my work away for free. If that ever changes and I charge a cent for an incomplete solution, your criticism will be more understandable.
