Due to the richness of the linguistic diversity of Europe, this dissertation focuses
on the design of a proposal of intervention. This proposal looks to a plurilingual teaching in
the higher secondary education courses. Plurilingualism has a range of transferable and
adaptable competences that may guide students. The methodology used is based on a learning
methodology where the student take a more active role in its own learning process as well as
in that of their classmates. This methodology also aims to develop plurilingual competences
within students as means of achieving social cohesion through the linguistic preservation
promoted by plurilingualism.Departamento de Didáctica de la Lengua y LiteraturaMáster en Profesor de Educación Secundaria Obligatoria y Bachillerato, Formación Profesional y Enseñanzas de Idioma
