摘要：“Non-native organisms are a major threat to biodiversity”. This statement is often made by biologists, but general conclusions cannot be drawn easily because of contradictory evidence. To introduce pupils aged 11-14 years to this topic, we employed an educational program dealing with non-native animals in Central Europe. The pupils took part in a lesson giving general information about the topic, followed by a species identification quiz. Attitude, emotions and state of knowledge of each pupil were surveyed throughout the program using standardized questionnaires (pre-/post- and follow up tests). One week after the first lesson, a field trip followed, focusing on one out of two non-native bird species in the city of Heidelberg, Baden-Württemberg, Germany. The first species was the Ring-necked Parakeet (Psittacula krameri) from the Indian subcontinent, and the second species was the East Asian Swan goose (Anser cygnoides). Life history information was delivered through a teacher and own observations during the excursions and after four weeks, the newly gained knowledge was tested in a third lesson. The “goose group” scored higher in goose-related questions, whereas the “parakeet-group” scored higher in their topic. The most impressive aspect of the whole program was, that the pupils rated the field trip per se as highest, and secondly, learning about unfamiliar species. Interestingly, the general attitude towards non-native species did not change as a result of this educational intervention.
