Nature and Types of Language in Subject Textbooks—Language of Mathematics Textbooks as an Example
The types and composition of language in subject textbooks involves the basic topic of textbook lan-guage theory,which is related to the status,value,research methods and research focus of language in subject text-books.Taking the typical member of the language of subject textbooks,language of mathematics textbooks,as an example,this research reveals the dependency relationship between language and knowledge by integrating the functional viewpoint and the actual-state viewpoint,and proposes the concept of"language of discipline paradigm"through analysis on the internal hierarchy of the language system in subject textbooks by constructing the relevant model.Language of discipline paradigm and general narrative language undertake the functions of knowledge repre-sentation,expression and knowledge teaching respectively,but language of discipline paradigm is more closely re-lated to knowledge objects,which should be the focus of subject language learning.
