Recognition and retrieval are different mental processes. When one re-reads a material, they recognize it. Recognition gives a false impression of “knowing” the material, whereas retrieval is a better measure of knowing. In order to get better at retrieval, one should practice retrieval, for example, by answering questions about the topic.

Well said. A great book that covers this (and suggests ways to practice retrieval) is called Make It Stick. I highly recommend it.
