Studying bilingualism and second-language acquirement through conversation and language acquisition analysis helps applied linguistics researchers develop theories about language learning. This information can then be used to shape language policy and more effectively teach students.

An associate degree is an undergraduate degree offered in the US and a few other countries. Associate degrees are a qualification below a bachelor's degree. Many students earn associate degrees during their first few years of higher education. Since they usually require about two years of study, these degrees can act either as job qualifications or as precursors to more advanced degrees.
