Stereotypes and prejudices have followed mankind in each and every part of the life cycle. Certain types of stereotypes and prejudices, in this case the ones closely related to animals that people meet, largely affect the relationship between men and animals. Therefore, some stereotypes and prejudices have made some animal species ‘glorified’ and referred to as “human’s best friend’, while some other, less lucky species, have been thought of as less worthy, repulsive, unattractive and discriminated. These stereotypes and prejudices come to existence thanks to influence of the society, culture and could be deeply rooted in humans. However, the same stereotypes can be prevented and are changeable through education, which is best started in the early learning stages of life. A research carried out and shown in this thesis had a goal of identifying those stereotypes and prejudices that students in the primary education associate with animals and because of those find some animals dangerous and others harmless. This research was conducted on 189 elementary school students, from grades 1 - 4 in three different schools in Zagreb. Through the analysis of data obtained through the research it is acknowledged that students were more afraid of the animals whose appearance they dislike, that boys tend to face less fear from animals than the girls and that there is not a significant difference in fear towards an animal present in grade one students than in grade four students. Additionally, in the thesis specific methods are shown that explain how to educate students and reduce the frequency or change already existing patterns of appearing stereotypes and prejudices on animals among lower primary students.
