Parametric Natura Morta
2018
Parametric equations can also be used to draw fruits, shells, and a cornucopia of a mathematical still life. Simple mathematics allows the creation of a variety of shapes and visual artworks, and it can also constitute a pedagogical tool for students.

Iterative Methods for Signal Reconstruction on Graphs
2016
In applications such as social, energy, transportation, sensor, and neuronal networks, big data naturally reside on the vertices of graphs. Each vertex stores a sample, and the collection of these samples is referred to as a graph signal. The product of the network graph with the time series graph is considered as underlying structure for the evolution through time of graph signal “snapshots”. The framework of signal processing on graphs [4] extends concepts and methodologies from classical discrete signal processing. The task of sampling and recovery is one of the most critical topics in the signal processing community. In this talk, we present some localized iterative methods, obtained by…

Stili cognitivi nell’apprendimento/insegnamento delle matematiche nella cultura cinese ed europea
2010
Tenuto conto del valore epistemologico della cultura cinese e di quella italiana con particolare riferimento all’analisi degli elementi cardine delle due tradizioni culturali come la filosofia, la logica, la lingua, la storia dello sviluppo del pensiero matematico etc., la ricerca condotta mira a comparare, in un’ottica interculturale, possibili schemi logico-argomentativi messi in atto da studenti italiani e cinesi, inseriti nelle classi italiane, evidenziandone analogie e differenze alla luce di analisi teorico/sperimentali condotte in Italia e direttamente in Cina.
BourbOulipo. Relazioni tra Oulipo e Bourbaki
2022
Il tema dell’influenza delle idee e delle metodologie bourbakiste su discipline che trascendono l’ambito matematico è stato frequentemente affrontato e, in particolare, la riflessione sul rapporto tra Bourbaki e Oulipo ha animato un appassionato dibattito in seno alla critica letteraria. Lo scopo di questo contributo è quello di investigare le relazioni tra Le Lionnais, Queneau e Roubaud - e più in generale l’Oulipo - e Bourbaki. Attraverso un esame comparativo tra i due gruppi si è evidenziata l’esistenza di un innegabile carisma del “matematico policefalo” sul movimento artistico-letterario. The theme of the influence of Bourbaki's ideas and methodologies on disciplines that transcend the…

Playing in Preschool Mathematics Education during SARS-CoV-2 pandemic: a phenomenological study with Italian teachers
2023
This paper discusses the results coming from a phenomenological study implemented with a sample of 110 Italian preschool teachers about the impact of the Covid-19 on preschool education. We investigate in which way the related pandemic phenomenon changed and is still changing the preschool pedagogical/didactic scenario about Mathematics playing. Through a questionnaire we qualitatively analyze and classify teachers’ argumentations highlighting their teaching approaches, their attitudes, their expectations in playing Mathematics in Preschool Education.
Problems with variation in teaching/learning Geometry: an example of Chinese Cultural Transposition
2022
This paper discusses some theoretical/methodological observation and some qualitative results coming from a Cultural Transposition experience, implemented in the Italian school context (grade 8), according to the methodology of variation, as one of the most significant problem solving approach in Chinese schools. The framework of the Cultural Transposition and the methodology of variation are presented as an important condition for “decentralizing” the didactic practice from a specific social and cultural context. We argue that looking at different teaching/learning mathematics strategies coming from East-Asia cultures can favor some cultural contaminations at school and allow students to a…
