Recipes for educational work do not really exist, particularly not recipes of similar value for all European societies. Youth and social workers, youth leaders and teachers most constantly adapt and react to the special requirements of young people and their particular social environment. DOmino tries to give some assistance to those working or planning to work with young people on peer group education projects. The different sections of DOmino contain some theoretical background on peer group education as well as different project descriptions, methods, quotes and stories from young people. The references to resources used have been put in brackets and the sources can be found in the bibliography at the end of this publication. DOmino is the result of different youth work practices in several European countries, both in the formal and informal educational sector. The editors have drawn from experiences in youth organisations, youth initiatives and schools. The existing diversity in Europe is also reflected in the presentation of different practical approaches, aimed at enriching the dialogue between and amongst young people and adults.
