Our project is about playing Mystery Skype game between students of schools in different countries. Asking "Yes/No" answered questions to each other, students will try to find each other's country without knowing each other's country beforehand. This activity will give them the opportunity to practice their English and to communicate in a real environment using a new method. Students from each country will ask questions the counterpart in turn such as "Is your country in the north/south of the Equator?" or "Does your country share borders with ....?" The activities in the project will strengthen students' vocabulary about geography and enhance their knowledge about foreign countries to be a good world citizen in future.
