Zur Sprache der Lernenden im Umgang mit negativen Zahlen
摘要
This paper investigates students’ use of language when dealing with negative numbers. On the one hand, theoretical and methodological considerations are made as to what ‘students’ use of language’ actually consists of and how a methodical approach to it can be found. On the other hand, these considerations are used to gain initial empirical insights into the students’ use of language when dealing with negative numbers. For this purpose, lexical means used by 7th grade students when explaining the concept of negative numbers in writing are collected and analysed in three steps: descriptive, didactic-normative and explanatory. Possible indications of students’ individual mental representations will be discussed for three linguistic phenomena that could be observed in students’ language.
