Trying to recall an entire concept or dialogue is a great way to strengthen learned knowledge. It forces you to apply it from your own understanding rather than by being guided from existing text.
For example when studying a language you can review dialogue containing new vocabulary and grammar concepts. Later when reviewing and revising (when the lesson is no longer fresh in your memory) you can look at each vocabulary word then try to recall and explain the lesson’s dialogue.
