‘Learning by moving’ addresses the need to develop language skills among Europe’s increasingly mobile citizens. They move around, travel, explore unfamiliar countries and places of interest, meet local people and interact in diverse social surroundings. They therefore need to be equipped with a stock of basic phrases to make themselves understood in unfamiliar circumstances. The project has developed a promotional campaign on public transport as a way of stimulating users to acquire the languages of minorities or of neighbouring countries. The means of transport include trolleybuses in Lithuania, trams in Poland, buses in Romania and Malta, underground and commuter trains in Germany and buses and city trains in Italy.
