Academic Encounters is an academic preparation series that uses a sustained content approach. There are two books in the series for each content focus: an Academic Encounters title that teaches reading, study skills, and writing; and an Academic Listening Encounters title that concentrates on developing students' listening, note-taking, and discussion skills. The two books may be used independently, or they may be used together to form a complete integrated-skills course. Many of the tasks in all Academic Encounters and Academic Listening Encounters books teach academic skills tested on the TOEFL® iBT test. Many tasks in the books focused on American Studies and those focused on The Natural World introduce students to topics and skills in the U.S. secondary school standards for U.S. history and culture (Academic Encounters: American Studies; Academic Listening Encounters: American Studies), and earth science and biology (Academic Encounters: The Natural World; Academic Listening Encounters: The Natural World).
