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 of bilingualism.

Immersion programs vary from one country or region to another because of language conflict, historical antecedents, language policy or public opinion. Moreover, immersion programs take on different formats based on: class time spent in L2, participation by native speaking (L1) students, learner age, school subjects taught in L2, and even the L2 itself as an additional and separate subject.

The first modern language immersion programs appeared in Canada in the 1960s. Middle-income Anglophone (English-speaking) parents there convinced educators to establish an experimental French immersion program enabling their children 'to appreciate the traditions and culture of French-speaking Canadians as well as English-speaking Canadians'.

Learning a foreign language has its assets, and studies suggest that immersion is an effective way to learn foreign languages. Many immersion programs start in the elementary schools, with classroom time being dedicated to the foreign language anywhere between 50% and 90% of the day. Learning a second or third language not only helps an individual's personal mental skills, but also aids their future job skills.Jean Piaget, a developmental psychologist, had a theory that stated that when a child faces an idea that does not fit their understanding, it "becomes a catalyst for new thinking". As a new language is completely foreign to a child at first, it fits perfectly as this "catalyst for new thinking".
