Language immersion

Language immersion, or simply immersion, is a method of teaching a second language in which the learners’ second language (L2) is the medium of classroom instruction. Through this method, learners study school subjects, such as math, science, and social studies, in their L2. The main purpose of this method is to foster bilingualism, in other words, to develop learners' communicative competence or language proficiency in their L2 in addition to their first or native language (L1). Additional goals are the cognitive advantages to bilingualism.
