DESCRIPTION:n this talk I will outline an emergent analytical framework\, 
 an adaptation of Orit Hazzan's three perspectives on abstraction\, for use
  in analysing textbooks. The three perspectives are described as familiari
 ty\, operationality and simplificability. Familiarity refers to the extent
  to which didactic materials reflect that which is already understood by t
 he learner\; operationality refers to the extent to which didactic materia
 ls provide scaffolding support\; and simplificability refers to the extent
  to which the didactic materials exploit transformations. The framework ha
 s been used on English and Taiwanese textbooks to examine the extent to wh
 ich abstraction\, as a mathematical process\, is supported.
