The paper presents a research carried out at the University of Cagliari during two academic years. The aim was to analyse the effect on students learning resulting from the introduction of a method based on questions and answers in a traditional large-classroom lecture. We investigated whether an interactive teaching approach, facilitated by an interactive software application based on mobile technologies, would lead to improved student engagement and learning outcomes in large-group of environmental engineering science lectures for undergraduate students. The goal was to assess the impact on learning outcomes, as well as the acceptance and appreciation of the students, of a lecture intermixed with questions and answers followed by analysis and discussion of the answers. In our experience we compared two different application of this methodology: with and without technology. The results obtained, in turn, were compared with those of a traditional lecture. Dispositivi mobili per aumentare l’attenzione e migliorare l’apprendimento Il contributo presenta una ricerca svolta all’Università di Cagliari nel corso di due anni accademici tesa ad analizzare le potenzialità di una modalità di lezione basata sull’uso frequente di “domande e risposte” gestite attraverso tecnologie. Abbiamo cercato di capire se un approccio didattico più interattivo, facilitato da un’applicazione software basata su tecnologie mobili, riesca a migliorare il coinvolgimento degli studenti e i risultati di apprendimento, in un contesto caratterizzato da un elevato numero di partecipanti. L’obiettivo era quello di verificare l’impatto sui risultati di apprendimento, oltre all’accettazione ed all’apprezzamento da parte degli studenti, di una didattica frontale intervallata da domande di verifica e dalla conseguente analisi e discussione delle risposte. Nell’esperienza sono state comparate due diverse modalità di applicazione di questa metodologia: con e senza le tecnologie e, i risultati ottenuti, sono a loro volta stati confrontati con quelli di una lezione tradizionale.

Among the actions to achieve the objectives set by the European Union in the "Fit for 55 Package" which sets a target of reducing net emissions of climatealtering gases by 55% by 2030, includes the EPBD Directive, with the aim of identifying and redevelop buildings with inadequate energy performance. The architectural assets subject to protection restrictions and the "complexes of immovable things that make up a characteristic aspect having an aesthetic and traditional value" remain outside the scope of application. In Italy, most of the historic buildings fall under this definition and among these the now abandoned prison structures, characterized by very high historical and architectural value but often left unused, spread practically throughout the national territory. Several local authorities introduced rules and prescriptions for the energy efficiency of the envelope into their regulations, but these remain applications limited to the local context, unable to give a universally valid procedure for the vast cultural heritage. The sporadic initiatives carried out up to now constitute a valid testimony on the possibility of overcoming the problems connected to the change in the use of the existing building. Starting from these successful cases, and not only at a national level, this research aims to provide a methodology for analyzing the existing and the today available "bacs", to support the design process for the reuse of these historic buildings. The proposed approach is based on environmental sustainability and tries to highlight those design choice parameters capable of solving the problems of integration with historical construction materials and ancient techniques constructive, overcoming the gap between the needs of the historical buildings and the available solutions.
