characteristics of textbooks

Peter, Kathy, & Wes:
1. Textbooks versus reference books
2. Textbooks can be collaboration between artist and teacher who collects a number of works that are compiled and put together into a textbook for the course.
3. Needs a pedagogical aim.
PROPOSED DEFINITION: collaboration between artists and a teacher. The teacher might be the one to insert the pedagogical aim.Typically, though, the author(s) assign the pedagogical aim.
Textbooks might tend toward de-skilling if they are comprehensive in designing the text for a particular aim.

Addressivity (Joan, Barbara, Lucie ):
1. Books with rich mathematical content could be made into a text if ... 
2. Just as one can disrupt the canonical text, that becomes a different invitation.
3. Author's intention for a canonical textbook:
  a. make money
  b. share their ideas about explaining, helping people learn, that they believe would benefit teachers and students

POWER OF GENRE: takes on cultural life of its own, molds peoples' intentions to conform to the needs of the genre. However a textbook writes in the textbook genre, pushing the boundaries, etc., the genre itself has a formatting power, the intentions encoded in the genre in a way take over and overpower the authors' intentions.

Textbooks are simultaneously constraining & enabling for teachers.
