I've always felt that most third space practitioners ARE 'teachers'. Often the roles require explaining or supporting the tools that are used to provide teaching and learning. This is much clearer in the Further Education (FE) or Vocational Education (VET) space where third space practioners have part of their role nominated as 'trainers'.

I hope we are moving towards a 'new' discipline. All third space practitioners are dynamic 'experts' in their field....as in, they are continually moving and adapting to the knowledge-area they work with.

The liminal space is a great way of describing this third space. As a 3rd space practitioner....we are in this transitional and transformative space.
