Rosetta Stone’s curriculum encouraged students to progress from seeing and recognizing pictures and vocabulary and hearing native speakers to actually speaking the target language. Language learners reviewed the alphabet, vocabulary, and intuitive grammar as well as the skills of reading, listening, pronunciation, and conversation without the use of translation exercises or detailed explanations. Lessons combined the introduction of new concepts, a review of recent material, and the production of key phrases. The curriculum was designed to be flexible so that learners could focus on meeting particular goals or developing certain abilities.
