The Third Degree.

Third space theory

E. Soja (1996) proposed a different way of thinking about space and spatiality. First and second spaces are two different, and possibly conflicting, spatial groupings where people interact physically and socially: such as home (everyday knowledge) and school (academic knowledge). 

Third spaces are the in-between, or hybrid, spaces, where the first and second spaces work together to generate a new third space. ‘Soja is anxious to avoid the common dualities of the social and the individual, culture/nature, production/reproduction, the real versus the imagined, (which pervade geographical analysis, arguing “there is always another way”

In short, deaf child campaigners want access to the deaf club, culture, language, community, in addition to Home (Space 1), education (Space 2), however with often no peers or mentors to interact with in mainstream, not really going to happen is it.  Isn't it just making a point mainstream isn't inclusive as activism sees it.  Deaf schools have gone we have to move on, and INCLUDE deaf people (Whether they want it or not!).
