Great and short article about the importance of being able to explain something. Medical students have the phrase See one, do one, teach one, when it comes to learning a new treatment or diagnostic method. I like that because it has the repetition baked in and each iteration one needs more depth of understanding. According to the article it sounds useful to add a fourth one: Write it down. In order to make it more easy to relearn the thing if you forget it.
