As a teacher I would kill for something like this, even if it's entirely paper-based instead of digitized. As you said, creating something like this is incredibly time intensive. There is a reason lots of free and paid teaching resources are basically worksheets, a textbook, and an answer key for "documentation." Anything more complicated is so much work. Even if you knew exactly what you wanted to do and how you wanted to implement it, you still have "beta test" it with students, determine the space of possible errors and misconceptions[1], make corrections, etc. I've thought about creating something like this for science, but I "only" teach the same lesson 4-5 times a day. Anything I learn, any corrections I want to make have to wait until next year when I teach that lesson again. Then if those changes don't work or I realize I need to take different changes, I have to wait another year to make them. Not exactly rapid iteration. [1]Not quite as easy as you might think. Students usually can't explain their misunderstanding very well or at all and you probably understand the material too well and it's hard to understand how to solve the problem any way but the correct way.
