This document discusses the differences between learning English as a second language (ESL) versus learning English as a foreign language (EFL). In ESL situations, students learn English in an English-speaking environment and need to use English outside of class as well. In EFL situations, students only use English in the classroom and speak their native language outside of class. Student motivation also tends to be higher for ESL learners since English is relevant to their daily lives, whereas EFL learners have less opportunity to practice English outside of class. Teaching approaches need to account for these contextual differences between ESL and EFL environments.
