RESEARCH ACTIVITIES

The scientific activity followed two main streams. Since 1986, with prevalent involvement till 2005 and continuing in present, in the field of Experimental physics of the elementary particles, touching also some topics in nuclear and atomic physics.
After a first phase of research in nuclear physics (anelastic scattering mechanisms in pbar^4He) and on forward pp elastic scattering, I studied the physics of the nucleon-antinucleon interaction, at low and high energy. In the framework of the study of the NNbar interaction at low energy, I collaborated to the experiment OBELIX (light meson spectroscopy and search of hybrid and exotic states), studying also topics in nuclear and atomic physics, related to the antinucleone/light nuclei interactions. At the same time I studied the production channels e-e+ --> hadrons at energies up to the J/psi (experiment Fenice, measurement of the e.m. form factor for the antineutron). During the '90 years I participated to studies in particle physics at high energy (experiment CDF, study of the top quark and its production in the ppbar interactions). In that period of time I participated to the design and setup of the silicon detector for the experiment Atlas.

Since 2016 I am participating to the experiment Muon g-2 at Fermilab (measure of the anomalous magnetic dipole moment of muons).
 

Since 1993, and prevalently since 2005, scientific activity was devoted mainly in the Physics Education Research, mostly regarding on topics related to curricular development and teacher formation. In this framework, I performed researches in Physics education, in national and international projects, focusing on the topics of the curricular development and teacher training.

Dr. Alberto Stefanel

Alberto Stefanel è un ricercatore dell'Università degli Studi di Udine, dal 2009, dopo una ventennale carriera come insegnante di matematica e fisica nella scuola superiore.
Dal dicembre 2015 al 2021 è stato direttore del Centro Interdipartimentale di Ricerca Didattica.

Si occupa di ricerca in didattica della fisica e la sua attività di ricerca si inquadra nel contesto dell’Unità di Ricerca in Didattica della Fisica dell'Università degli Studi di Udine.
Insegna Fisica nel Corsi di Studi di Agraria, Scienze e Tecnologie della natura, Viticoltura e Enologia, Scienza degli alimenti dell’Università di Udine.

Si è laureato in Fisica presso l'Università di Firenze nel 1983, con una tesi mirata alla costruzione della teoria del processo Light Induced Collisional Energy Transfert (LICET) basato sul metodo della fase stazionaria nell’approssimazione a due e a tre livelli.

Dottorato di Ricerca in Matematica e Fisica presso l'Università di Udine nel 2006, con una tesi sulla didattica della meccanica quantistica nella scuola secondaria superiore e, in particolare, lo studio sui percorsi di apprendimento degli studenti sui concetti di base della teoria quantistica e il significato concettuale del suo formalismo; strategie di formazione degli insegnanti per implementare proposta innovativa sulla meccanica quantistica nella scuola secondaria superiore.

La sua attività di ricerca è documentata in oltre 300 lavori, di cui la metà a livello internazionale) riguardanti: la didattica della fisica moderna nella scuola superiore; studi cognitivi sul ruolo di ambienti di apprendimento informali e attività hands-on / minds-on nell’attivare il processo di apprendimento di bambini della scuola primaria su stati e processi termici, elettromagnetismo, fenomeni meccanici, suono, energia; ruolo delle TIC nella didattica della fisica; formazione degli insegnanti all’innovazione didattica; ruolo di ambienti in rete per l’apprendimento della fisica sia nella didattica universitaria, sia nella formazione insegnanti.

In merito a quest’ultimo ambito sono stati effettuati studi su come supportare le attività in presenta con attività in rete che favorissero l’acquisizione di competenze di tipo disciplinare e di tipo metodologico soprattutto collegate al laboratorio sperimentale e come proporre attività sperimentali nel contesto di una didattica essenzialmente condotta a distanza.
