As part of that joint conference, a workshop on language and education in Africa was organized by Carolyn Adger of the Center for Applied Linguistics.

In a small group, a speaker uses an often unwritten and endangered mother tongue that is rarely used in school. A national indigenous language-written, widespread, sometimes used in school-surrounds it. An international language like French or English, a vestige of colonialism, carries prestige, is used in higher education, and promises mobility-and yet it will not be well known by its users.
