This course has been designed taking into account the needs of the teachers-to-be concerning the functioning of the foreign language in different contexts. The purpose of the course is to enhance the students’ critical understanding of the social production of language and the relation this production has with the form of the language.  This link can help language users, and in this case future teachers of the foreign language, explain how texts make the meanings they express. By means of analytical exercises, students can identify in a critical way, the written and spoken authentic discourse and the  meanings they can convey.
