2 Teoria della deriva dei Continenti (Wegener, 1912)
Studio della morfologia dei fondali oceanici (anni ‘50) Paleomagnetismo (anni ‘50) Studi sull’inversione di polarita’ e le bande di anomalie magnetiche (anni ‘60) Teoria di Hess (1962), Espansione fondali Studi sull’eta’ dei fondali oceanici (1968) The link between biology and citizenship is extensive. In fact, citizens are constantly expected to take up positions on issues with conceptual or technological links to biology. Issues as stem cell research, genetic engineering, cloning, genetically modified foods, environmental problems, biomedical research and animal rights. These issues are often presented by the media with conflicting and incomplete information.

3 Ne’ padre, ne’ data precisa di nascita
Teoria della tettonica a placche Ne’ padre, ne’ data precisa di nascita Serie di articoli alla fine degli anni ‘60 Teoria Globale But before discussing the findings I would like to explain very briefly the title and the rationale of the study. The first part of the title reflects the first purpose that was exploring the relationship between School Biology and Global Citizenship Education, as biology teachers experience, interpret and understand.

4 Origine ed evoluzione dei fondali oceanici
Orogenesi Origine ed evoluzione dei fondali oceanici Movimento orizzontale (ma non ‘deriva’) dei continenti Cicli di Wilson (di separazione e collisione continentale Fenomeni sismici Fenomeni vulcanici The link between biology and citizenship is extensive. In fact, citizens are constantly expected to take up positions on issues with conceptual or technological links to biology. Issues as stem cell research, genetic engineering, cloning, genetically modified foods, environmental problems, biomedical research and animal rights. These issues are often presented by the media with conflicting and incomplete information.

6 Placche: porzioni di litosfera, ognuna incastrata nell’altra, come le tessere di un enorme puzzle
In order to explore the two specific research questions : Twenty-one biology teachers from thirteen different Local Authorities of Scotland have participated in semi-structured, in-depth interviews, in order to explore the following research questions: (1) how do educators conceive global citizenship education in their role as secondary school biology teachers? (2) What are biology teachers’ conceptions of the link between evolutionary biology and global citizenship education?

7 Si noti come gli epicentri dei terremoti siano localizzati lungo I bordi delle placche
