TL;DR: The focus of this research is how Sicilian state university mathematics professors faced the challenge of teaching via distance education during the first wave of the COVID-19 pandemic, and how they adapted to the new teaching modality.

TL;DR: In this paper, a sequence of classroom activities on Euclidean geometry, both plane and space geometry, used to make three dimensional geometry more catchy and simple is presented, consisting of a guided research activity that leads the students to discover unexpected properties of two apparently distant geometrical entities, quadrilaterals and tetrahedra.

TL;DR: In this article, the centroid of any finite set of po ints of the space is introduced and some general properties of centroids are applied to different types of polygons and polyhedra.

TL;DR: In this article, the authors present an experimental teaching activity conduced in some primary, middle and high schools in Sicily, which concerned several topics of graph theory, in particular the approach to teaching Eulerian graphs.

TL;DR: This article studied mathematicians' experiences as learners of mathematics and their views on memorising in students' learning, and found that personal experiences of memorising underpin attitudes to memorizing in teaching mathematics and that further investigation is warranted on this little researched aspect of "coming to know" mathematics.
