alt Hacker NewsI had thought I saw somewhere that learning is specifically better when you are wrong, if the feedback for that is rapid enough. That is, "guess and check" is the quickest path to learning.
Specifically, asking a question and getting an answer is not a general path to learning. Being asked a question and you answering it is. Somewhat, this is regardless of if you are correct or not.
I hated when doing math homework and they didn't give me the answer sheet. If I could do an integral and verify if it's correct or not, I could either quickly learn from my mistake, or keep doing integrals with added confidence. Which is how I learned the best. Gatekeeping it because someone might use the answers wrong felt weird, you still had to show your work.
