This volume focuses (self-)critically on sloganization as an emergent phenomenon in language education discourse. Motivated by an increasing uneasiness with a number of widespread concepts in current language education research that have become sloganized, this volume comprises a collection of chapters by international scholars that scrutinize the discourse of language education, identify popular slogans and reconstruct the sloganization processes. It promotes critical self-reflection of scholars and professionals in the field of language education - a field that has widely been dominated by the need to develop innovative approaches and practices, at the expense of self-critical work that attempts to situate the field and its approaches within wider historical, cultural and conceptual contexts.
