Teaching method
Classes with a presentation of the subjects articulated with the resolution of exercises that allow a better understanding of theoretical concepts and help to encourage student participation during class .
Learning is supplemented by oral presentation of papers by students, exercises to be solved inside and outside the classroom and laboratory work (production of glass, production of films on glass, measuring absorption spectra of UV- Vis and dilatometry ) accompanied by written reports of the experimental work.
