Foreign language learning and teach

Foreign language learning and teaching refer to the teaching
or learning of a nonnative language outside of the environment
where it is commonly spoken. A distinction is often
made between ‘foreign’ and ‘second’ language learning.
A second language implies that the learner resides in an environment
where the acquired language is spoken. In the area
of research, the term second language acquisition (SLA) is a
general term that embraces foreign language learning and investigates
the human capacity to learn languages other than
the first language once it has been acquired. Scholarly inquiry
into the acquisition of a nonnative language includes the disciplines
of psychology, linguistics, language pedagogy, education,
neurobiology, sociology, and anthropology. Inquiries of
learning and teaching innovations have provided new insights
into successful language learning strategies and environments
designed to increase language achievement and proficiency.
