Mathematisches Wissen, erworben in empirischen Theorien

Autor: Burscheid, Hans Joachim, Struve, Horst

Following the processing of individual topics of elementary school mathematics as content of empirical theories the question is adressed wether the associated conception of mathematics finds itself under established concepts, and how it can be suppor

The Steiner-Lehmus theorem and 'triangles with congruent medians are isosceles' hold in weak geometries

Autor: Pambuccian, Victor, Struve, Horst, Struve, Rolf

We prove that (i) a generalization of the Steiner-Lehmus theorem due to A. Henderson holds in Bachmann's standard ordered metric planes, (ii) that a variant of Steiner-Lehmus holds in all metric planes, and (iii) that the fact that a triangle with tw

Die Bedeutung empirischer Theorien f\'ur die Entwicklung von Gruppierungen

Autor: Burscheid, Hans Joachim, Struve, Horst

Reviewing Piaget's psychology of reasoning by the mathematical educators of the Federal Republic of Germany late in the 1960th the concept of grouping has been understood similar to a mathematical structure. Possibly to consider empirical theories ca

Report

Empirische Theorien im Kontext der Mathematikdidaktik

Autor: Burscheid, Hans Joachim, Struve, Horst

At two examples dealt with in methodologically different ways it will be pointed out how the concept of an empirical theory (in the sense of the Structuralists) can be useful to specify contents relevant to maths didactics.
