Language immersion

Language immersion, or simply immersion, is a technique used in bilingual language education in which two languages are used for instruction in a variety of topics, including maths, science, or social studies. The languages used for instruction are referred to as the L1 and the L2 for each student, with L1 being the student's native language and L2 being the second language to be acquired through immersion programs and techniques. There are different types of language immersion that depend on the age of the students, the classtime spent in L2, the subjects that are taught, and the level of participation by the speakers of L1. Although programs differ by country and context, most language immersion programs have the overall goal of promoting bilingualism between the two different sets of language-speakers. In many cases, biculturalism is also a goal for speakers of the majority language (the language spoken by the majority of the surrounding population) and the minority language (the language that is not the majority language). Research has shown that such forms of bilingual education provide students with overall greater language comprehension and production of the L2 in a native-like manner, especially greater exposure to other cultures and the preservation of languages, particularly heritage languages.
