I have nothing against the quote “I hear I forget, I see I remember, I do I understand.” It’s very meaningful…
But, please don’t attribute it to Confucius!
The closest that can be found is from Xunzi.
《儒效篇》荀子曰: “不闻不若闻之，闻之不若见之，见之不若知之，知之不若行之；学至于行之而止矣。”
(Not hearing is not as good as hearing, hearing is not as good as seeing, seeing is not as good as knowing, knowing is not as good as acting; only when there is action can learning be considered as accomplished)
