“Interpretation is an educational activity which aims to reveal meanings and relationships through the use of original objects, by first-hand experience, and by illustrative media, rather than simply to communicate factual information", (Tilden, 1957).Every year millions of people visit natural and cultural heritage sites. This is a great opportunity for informal and non-formal learning. InHerit wants to present heritage interpretation as the ideal tool and approach to make place-based learning more effective, interesting and efficient and wants to present heritage (tangible and intangible, natural as well as built) as the ideal learning space in a ‘learning cities & regions ecology’ for citizens to develop key competences. InHerit aims to build heritage staff capacity for competence oriented non-formal learning in inspiring contexts that improve the adult learning potential at heritage sites through professional development of managers and educators at these sites. In-service training courses at European and national level shall further their competences to realize the full potential of Heritage Interpretation for non-formal and informal learning. Outcomes:- a Grundtvig-IST course for site managers and adult educators to facilitate competence oriented learning experiences that reveal the European dimension of heritage to visitors - course materials in different languages- an integral validation system- pilots and recommendations to exploit this course for national contexts- a strategy for advanced European level training courses- policy recommendations outlining improved framework conditions for more professional HI thus enhancing learning through Europe's rich and diverse heritage.Via more professional HI museums and heritage sites can serve as a low-threshold gateway to lifelong learning in non-vocational contexts. People with negative feelings towards education will gradually appreciate learning and overcome stereotypes by broadening their horizon.
