'Reflective didactics' is a method based on a theory of interpersonal (teaching) communication that proceeds from experience gleaned in classroom reality, makes that experience the object of theoretical reflection, and derives from that reflection concepts and material for use in teaching situations. The thematic emphasis of the present study is overt and covert multi-lingualism in schools. After discussing the empirical evidence for this assertion, it addresses its central purpose, which is to provide encouragement for as many learners as possible by means of suitable didactic measures designed to make the most of individual potentialities in the field of writing.
