Schools and learning environments for children and youth can go global today if teachers include cultural diversity in the curriculum of the school. Therefore they have to be aware of different attitudes of the children, as far as their different backgrounds. They have to create an international learning environment, which helps to create cultural competence among the children.
To be able to create lessons like that, teachers have to go on teacher trainings and join in international committees. In school you can either use different kind of material, which helps studens to become more open minded concerning different cultures. There are all kinds of portals you can use as a teacher, for example the "e-Twinning portal", where you can register and find a school for your class that wants to exchange information via e-mail or skype. This is a very modern way for children to communicate with each other and will help them to get closer to a different culture. You can have the children choose, which country they want to communicate with and talk about the cultural differences that appear during the communication.
Furthermore, there are many more different portals for example "The image of the other", it is basically the same idea to choose a country and a class to participate with. These projects might already start in Kindergarden or preschool. It is even better to start it early, because the younger the children the open minder they are. You may invent different kinds of projects, for example projects about friends, or postcards or the comenius project. As you could see, there are a number of different ways for schools to create a learning environment for children and youth to help them going global today.
