16. ESTRUTURAS DE FULERENOS: ESTABELECENDO INTERFACES NO ENSINO DE MATEMÁTICA E QUÍMICA EM NÍVEL SUPERIOR
The objective of this paper is to study fullerene geometry properties and attempt to stablish a dialogue between the teaching of mathematics and chemistry concepts using hands-on cardboard geometric models, in classroom, in order to facilitate the understanding of fullerene structures. This approach to the study of such molecules represents a unique opportun

17. Conocimiento Especializado del Profesor de Matemáticas acerca del Infinito
Abstract Infinity is a concept underlying many concepts present in school mathematics. In this article, we explore teachers' knowledge about infinity from the perspective of the professional knowledge, which is used to deal with infinity in a classroom. For that purpose, we use the discussion of vignettes of simulated situations where different kinds of unde

18. HILBERT BETWEEN THE FORMAL AND THE INFORMAL SIDE OF MATHEMATICS
Abstract: In this article we analyze the key concept of Hilbert's axiomatic method, namely that of axiom. We will find two different concepts: the first one from the period of Hilbert's foundation of geometry and the second one at the time of the development of his proof theory. Both conceptions are linked to two different notions of intuition and show how H
