flashcards and memorization

Based on some of the reading we have done, about read and look up activities, and my own experience in my class practicum, I am starting to re-evaluate my perspectives on the role of memorization in language learning. So I have practiced a new language recently to see if memorization might be effective. I combined it with lots of reading. Although, I used flashcards and read several different materials. I have been making good progress when combined with reading activities. In particular, the DS language coach series flashcard games also seen effective when combined with reading. I have not been speaking the language. Currently, I am going through what Krashen refers to as a "silent period". I also have several different listening resources I have been using. I have been aiming to find reading material that I have mostly reviewed in flashcards. While I do believe interaction plays a vital role in language learning, I have become increasingly interested in the vitality of it or the necessary percentage of it.
