The research work concerns the analysis of the foundations of Quantum Field Theory carried out from an educational perspective. The whole research has been driven by two questions: • How the concept of object changes when moving from classical to contemporary physics? • How are the concepts of field and interaction shaped and conceptualized within contemporary physics? What makes quantum field and interaction similar to and what makes them different from the classical ones? The whole work has been developed through several studies: 1. A study aimed to analyze the formal and conceptual structures characterizing the description of the continuous systems that remain invariant in the transition from classical to contemporary physics. 2. A study aimed to analyze the changes in the meanings of the concepts of field and interaction in the transition to quantum field theory. 3. A detailed study of the Klein-Gordon equation aimed at analyzing, in a case considered emblematic, some interpretative (conceptual and didactical) problems in the concept of field that the university textbooks do not address explicitly. 4. A study concerning the application of the “Discipline-Culture” Model elaborated by I. Galili to the analysis of the Klein-Gordon equation, in order to reconstruct the meanings of the equation from a cultural perspective. 5. A critical analysis, in the light of the results of the studies mentioned above, of the existing proposals for teaching basic concepts of Quantum Field Theory and particle physics at the secondary school level or in introductory physics university courses.

Con questo lavoro ci si propone di esaminare il panorama del fumetto nel mondo a partire dalle ricerche di mercato a disposizione e l’argomento è stato scelto perché poco trattato in letteratura. I risultati ottenuti hanno portato a galla grosse lacune, soprattutto per quanto riguarda il reperimento di informazioni nel mercato del fumetto in Italia, all’interno del quale si è notato un cambiamento delle preferenze dei consumatori relativo al supporto da utilizzare per la fruizione dei contenuti, con uno spostamento verso il digitale.

This dissertation aims to analyse the development of the deliberative model of democracy in the U.S., both in an empirical and theoretical levels, from its origins in the eighties of the last century until now. In the first part we study the political and historical elements that build the crisis of the Liberal political system in the seventies in the U.S. and its effects on the political behaviour of citizens. In the second part we discuss the origins and development of the deliberative theory of democracy, its main authors, approaches and elements. The key aspect of this model of democracy is to reverse the apathy and strength the political participation of citizens through public deliberation. In the last part we expose the practical level of the deliberative democracy: how this theory of has been put into practice in the American political domain. We describe the main projects of deliberative democracy rose from civil society from the eighties until today. Finally, we expose the James Fishkin’s proposal of deliberative poll. This is the link between the empirical and theoretical levels of the deliberative model of democracy.
