acculturation theory definition
Acculturation Theory is a second language acquisition theory by John Schumann. Interestingly, Schumannâs theory is not based on the mental processes necessary to acquire a language, nor the nature of language itself.The Acculturation Theory focuses in socio-cultural factors in language teaching and learning.n brief, the Acculturation Theory posits that, in learning a second or a target language, certain social factors come into play that either inhibit or aid in the acquisition of that target language.
