The unity of Euclidean geometry, destroyed by the discovery of the non-Euclidean worlds, is recomposed in the new Pre-Absolute Geometry Γ, subsuming the properties shared by the four geometries: Euclidean, hyperbolic, spherical, and elliptic. Once the four geometries have been created ex-novo, theory frees itself from them and shows its absolute independence. Drawing on the work of Euclid, the new geometry is easily accessible to students and teachers.
Early hospitalization is a critical experience in a child’s life, with personal and relational effects and repercussions on school learning and achievement. In this paper, we will illustrate the main studies conducted on the psychosocial impact of hospitalization on school-children’s well-being, with a specific focus on surgical intervention, as a particularly invasive medical procedure. We will then present an explanatory research to investigate the mathematical abilities of a group of children with a recent history of hospitalization, who has undergone at least one surgical operation, at the beginning of primary school. Finally, we will compare their mathematical competence with that of a control group of the same age and schooling.
This is the second part of an author’s article published in QuaderniCIRD No. 17/2018. It presents the steps of an educational path in geometry aimed at students in secondary school. The focus is mainly on constructions of quadrilaterals. The author shows various ways in which the quadrilaterals can be constructed. He does it by folding paper to reproduce the shapes of the construction that each time can be taken as a starting point.
A workshop called Attitudes towards mathematics was set up in order to give mathematics teachers information on students’ measurement of «attitude to mathematics». After the introduction of some basic theoretical notions on different concepts of attitude, an easy-to-apply instrument to collect data related to these different concepts is presented. The creation of a database is also explained and different types of analysis, using elementary descriptive statistics, are shown. 110 third-year students (64 men and 46 women) of two secondary schools in Trieste (Friuli Venezia Giulia, Italy), provide the necessary data. Attitude towards mathematics is analyzed among the whole group and in those subgroups, who show negative, neutral or positive tendency. The data concerning male and female students are also studied separately to see if there are differences in gender issues.
