The Museum of Education of Padua University was formally established in 1993 to collect, study and exhibit all materials related to the history of education, following males and females in and out of the school from birth to the adult life. Therefore, during its first twenty years of activity, the Museum of Education was first of all a place of scientific research, as evidenced by a lot of publications of national and international scholars who studied, in particular, the collections of textbooks and exercise books.Constant and parallel has been also the activity destined to the initial training of teachers and to the updating of those in service. To the teachers in training are destined specific workshops linked to the teaching of history of education both included in the degree course that prepares future teachers in primary schools; they find in the rich sorting out of experiences, and even in the mistakes that derive from the past, a firm anchorage for the construction of their professionalism. Besides, the teachers in training can follow the class during the visit; by observing the behavior of students in extracurricular contexts, they significantly integrate the skills matured during the training in the classroom. Initiatives of in-depth scientific analysis (often realized on the occasion of thematic exhibitions) and activities of methodological upgrade, especially with regard to the teaching of history, are addressed to teachers already operant. In the Museum's website (www.museo.educazione.unipd.it) you can see some of the materials prepared in internet documenting what has been done.
