Wow, glad we came to an agreement, I actually didn’t expect that.
Not sure if that’s a feature or a bug.
That’s on purpose, glad you noticed! Green = the correct answer. Yellow = not the correct answer, but a prefix of it (that includes an empty string). Red = neither the correct answer, nor a prefix of it.
Like, if the correct answer is “42”, then “4″ is yellow, because for all I know maybe you are halfway to writing the correct answer, so I don’t want to scare you needlessly. (Though maybe I should later update it to red when you leave the text field… and update back to yellow when you return? Nah, sounds like too much work.)
Seems to happen to me here a lot more often than IRL.

The only problem with the box remaining yellow that I see is that it conveys partial information, because it turns red if the digit is wrong.
In other words, if a student wanted to fill out the boxes by brute force, without actually doing any math, just by trying numbers, they’d be able to get to multi-digit answers by trying out 1-9 until they found the number that didn’t cause the box to turn red, then moving on to the next digit.
Off the top of my head, the simple way to fix it would be to do the correctness check after focus leaves the box (triggered by leaving the box, as it were); that can apply to every box and ensures the student can’t brute-force the answer as above.
For some reason I procrastinate for months when trying to write articles, but can write an insanely long comment whenever I get angry about something. So here is a story about “constructivism” in education, as a Hacker News comment.
Give me a few more months, and I will probably rewrite it to a LW article, and then it will get like 5 karma total, heh.
I mean, what other response is possible when someone is wrong on the internet?
Either way, I’m looking forward to it.
Edit: after reading the comment, I feel like I have a better understanding of how we might’ve been talking past each other a bit. I do agree with your position.
Also, the history of education is a terrifying and depressing subject, in my experience.

I like coming to agreements too!
