In my French class, we create Quizlet cards for every set of vocabulary we are given. Everyone memorizes the vocabulary, but the vocabulary tests require that we put the words into sentences. Therefore, it's doesn't mean anything to memorize the verb 'plaire' (to please) if you don't know how it's used and how to conjugate it. I think an overdependence on rote memorization via flashcards holds a lot of my classmates back since they don't know how to use the words in conversation. Flashcards are a good way to memorize the words, but not a good way to learn them.
