This article reviews research on language learning strategies from 1970-2006 and proposes revisions to the theoretical framework. It discusses strategies used for both learning and using a second language. The author draws on previous works and studies college students learning a language. Two important aspects are defining strategies and using them in learning. The relationship between subconscious activity and strategies is explored, showing how they shape learning preferences and processes. The article recommends viewing strategies as an integral part of learning, not just for speeding it up. Learning depends more on the strategies available and best fitting a learner's preferences and intelligence. While much research has been done, theoretical criticisms have persisted for over two decades.
