化学知识三重表征的话语意义探析

Discourse Meaning of Triple Representation of Chemical Knowledge

基于科学哲学和语言学理论,强调化学学科中的三重表征的话语意义,旨在帮助学生将头脑中的三重表征思维用语言科学地表达出来并进行社会性交往。在明确三重表征与话语的关系的基础上,借助于相关教学片段,对三重表征的话语意义(语法学、语义学和语用学意义)进行探析,将宏观-微观-符号表征中各自的语言内部联系以及彼此间的话语表达关系解构出来,从而全面提升学生在建构、关联及转换表征过程中的交往效率。最后针对相关教学问题,提出了3条教学策略。

Based on the theories of philosophy of science and linguistics,the discourse meaning of triple representation in chemistry was emphasized, which aimed to help students to express the triple representation in their mind scientifically and to communicate with one another. On the basis of the clarifying the relationship between triple representation and discourse, the discourse meaning(such as grammar, semantics and pragmatics meaning) of triple representation were inquired by the means of the analysis of relevant teaching transcripts. The internal connections and the relationship of language and discourse expressions between macro, micro, and symbolic representation were deconstructed. It helped students to communication more efficiency while they were constructing, connecting and transforming different kinds of representations. Finally, three teaching strategies were put forward which aimed at solving related teaching problems.
