On the complexity of the 2k-ary and of the sliding window algorithms for fast exponentiation
Full text linkWe present the 2k-ary and the sliding window algorithms for fast exponentiation. We give a precise formula for the error terms of their complexity and we discuss how to choose the parameters or the exponent optimally
GeoGebra: idee per un progetto : ovvero, un rettangolo è sempre un rettangolo?

Orologi, ruote, crittografia, poligoni stellati
No full textLo scopo di questo laboratorio è introdurre l'aritmetica modulare, nota anche come «aritmetica dell'orologio», e vedere come si può usare in crittografi
Leggere e comprendere. Una prova sperimentale per le matricole di Matematica.
No full textNell'articolo si presenta una prova rivolta alle matricole della laurea triennale di matematica e gli esiti della sperimentazione. La prova mira a verificare la capacità di leggere un testo nella convinzione che in matematica la comprensione è davvero raggiunta quando si applica e produce conoscenza
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Making Good of a Pandemic: A Long-Distance Remedial Summer Course in Calculus
Full text linkWhat do you do when a change in enrollment policies leaves you with more than 600 students in a first-term university calculus class, three-quarters of those students had a failing mark in mathematics in the pre-enrollment test, you planned a series of remedial activities for the second term, and the COVID-19 pandemic shuts the university down with a two-day notice? The pandemic hit instruction with might, forcing schools and universities that were timidly experimenting with digital tools to reinvent themselves in days. The pandemic also offered incentives for creative solutions that, in normal times, would have been considered fit for submission to the committee for recursive committee submissions at best. This paper narrates a teaching experience of how we proposed and managed an at-distance remedial course in August that not only catered to more than twice the number of students expected by our best forecasts, but was a very good success once its effectiveness was compared to the outcomes predicted by the pre-enrollment test scores. We expose the design of the course and link its measured effectiveness with both its design and student engagement; in particular, we show that a different approach to the examination of cognitive load and to fostering student–teacher and student–student communication thanks to digital mediation could be effective in countermanding the math-induced drop-out phenomenon in STEM
