Politeness Theory
Brown and Levinson have devised a cross-cultural theory of politeness, according to which everybody has a positive and negative “face”. Positive face is the want to be desirable to others (approval). Negative face is the want to be unimpeded by others (autonomy). I am interested in how the politeness theory applies to learning, in particular how politeness strategies used by tutor to influence learning experience.
