Searching the internet for learning materials through didactic indicators
2007
Internet offers a huge amount of didactic materials that can be used in creating new online courses. However, those materials need a deep analysis to understand their context and contents before their potential use. As a consequence, the search of didactic material in internet is often quite tedious and time consuming so the searcher usually limits his/her analysis to the first found web pages . To help users in finding efficiently and timely the most appropriate online materials, we have developed a system, called SAXEF (System for Automatic eXtraction of lEearning object Features), that is capable to automatically extract the didactic indicators (a sort of DNA) of any web page (or group o…
Structuring didactic materials on the Web (Struct)
2009
There is an universal agreement that the structuring of didactic materials helps the student in his/her learning process when dealing with such materials. It is then important for the teacher or a student to choose among different structures so to use the one that best conveys the desired knowledge. This need is nowadays a priority also in the e-learning world since several e-learning courses exist on the web and many more are created every day. Unfortunately, most of the existing e-learning platforms offer just a single way to organize the course contents (book structure). Whoever is interested in organizing the course contents in a different way (e.g, with a concept map) must use specific…
Ἀνὰ μέσον ἡδονῆςτε καὶ λύπης: Avidità umana e filantropia alla prova dell’oro in Diodoro
2021
In the Third book of his Bibliotheca, Diodorus Siculus includes an account of the Egyptian gold mines and describes the terrible living conditions of the slaves who are exploited to extract the metal. In this regard, Diodorus’ source is the historian Agatharchides of Cnidus, whose account is handed down by the Byzantine writer Photius. The comparison between the two texts allows scholars to highlight the different historical perspective of Diodorus, which privileges a worldview dominated by philanthropy and compassion for the most peripheral humanity. Further confirmation arises from the description of the Iberian mines (V 35-38), which Diodorus derives from the historian and philosopher Po…
SORTING ALGORITHMS FOR 5TH AND 6TH GRADE STUDENTS: GREEDY OR COOPERATIVE?
2016
Our main research goal lies in a proposal to discuss the lack of, and improve, activities in the Italian school curriculum about discrete mathematics, computer algorithms and cryptography, especially for 3rd to 8th grade students. Activities of this kind are missing almost entirely, both in the school programs and in textbooks, despite many agree that they can be really useful to improve both general skills, such as reasoning and modeling, and skills particular to discrete mathematics, such as algorithmic and recursive thinking. A survey among various grades teachers confirmed this. The activity we are going to describe fits into a wider research project. Design research, chosen as the meth…

L’evoluzione della didattica generale dalla storia all’attualità
2015
La costruzione sistematica del sapere didattico è stata possibile quando i risultati delle scienze-fonti della didattica sono stati rielaborati dal punto di vista di chi studia il processo di insegnamento-apprendimento, per la formulazione di ipotesi articolate che sono state sottoposte a verifica mediante l’esperimento oppure con l’osservazione sistematica, secondo le due grandi tradizioni della ricerca quantitativa e qualitativa. Tre sono i periodi essenziali in cui si può suddividere la recente storia della ricerca didattica in Italia: il periodo pioneristico (1954-1974), quello del pieno riconoscimento accademico (1974-1994) e quello della maturità scientifica (1994-2014). The systemati…
Bridging probability and calculus: the case of continuous distributions and integrals at the secondary-tertiary transition
2018
International audience; This paper focuses on two mathematical topics, namely continuous probability distributions (CPD) and integral calculus (IC). These two sectors that are linked by the formula P(a<=X<=b)=int_a^b f(x)dx are quite compartmented in teaching classes in France. The main objective is to study whether French students can mobilize the sector of IC to solve tasks in CPD and vice versa at the transition from high school to higher education. Applying the theoretical framework of the Anthropological Theory of the Didactic (ATD), we describe a reference epistemological model (REM) and use it to elaborate a questionnaire in order to test the capacity of students to bridge CPD and IC…
Seeing reality through Einstein's eyes: a teaching proposal for special relativity
2021
The teaching of Special Relativity is still a critical issue not only for students but also for teachers. In this paper, we describe the trial of a learning unit on the Special Relativity topic based on Minkowski's approach through spacetime diagrams, following the results in pedagogical researches in this field. The main innovation of our project consists of a mechanical instrument: it allows to physically and mechanically represent Lorentz’s transformations by hands, exploring the effects of a change of the reference frame. Teachers and students can deal “by eye” with unusual phenomena as the loss of simultaneity, time dilation, length contraction, relativistic addition of velocities and …
