Journal ArticleDOI
Teaching mathematics at distance: A challenge for universities
Rosalinda Cassibba,Daniela Ferrarello,Maria Flavia Mammana,Pasquale Musso,Mario Pennisi,Eugenia Taranto +5 more
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.
Journal ArticleDOI
Analogy and Dynamic Geometry System Used to Introduce Three-Dimensional Geometry
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.
Journal ArticleDOI
On the altitudes of quadrilaterals
Biagio Micale,Mario Pennisi +1 more
TL;DR: In this paper, a generalization of the maltitudes is given, and a larger family of quadrilaterals for which an analogous property of concurrency holds is determined and studied.
On the Centroids of Polygons and Polyhedra
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.
Journal ArticleDOI
Quadrilaterals and Tetrahedra.
TL;DR: In this paper, the existence of an analogy between quadrilaterals and tetrahedra has been investigated and some properties that hold for both families of figures have been shown.
