„Wozu muss man denn das beweisen?“

Vorstellungen zu Funktionen des Beweisens in Texten von Schülerinnen und Schülern der 8. Jahrgangsstufe

Abstract

Meta-knowledge about mathematical argumentation and proof is a prerequisite for the development of proof competence. For instance, learners should know about the functions of proof and proving. In this article, several categorial systems for functions of proof and proving are discussed and a modified categorisation is presented. The applicability of this model is examined in a rating of functions of proof and proving distinguished by students in text productions in which they describe mathematical proof.
