The eTwinning action is an initiative of the European Commission that aims to encourage European schools to collaborate using Information and Communication Technologies (ICT) by providing the necessary infrastructure (online tools, services, support). Therefοre, teachers registered in the e-Twinning action are enabled to form partnerships and develop collaborative, school projects in any subject area and collaborate with teachers from other European countries (at least two teachers from two different European countries are needed). The primary workspace for the eTwinning action is the e-Twinning Portal (www.etwinning.net) and it is available in twenty-five languages. Teachers registered in the e-Twinning action, also called eTwinners, find each other, communicate, share resources and collaborate through the e-Twinning platform.
The main concept behind e-Twinning is that schools are paired with another school elsewhere in the Europe and they collaboratively develop a project, also known as eTwinning project. The two schools then communicate using the Internet (for example, by e-mail or video conferencing) to collaborate, share and learn from each other. eTwinning encourages and develops ICT skills as the main activities use information technology. Being 'twinned' with a foreign school also encourages cross-cultural exchanges of knowledge, fosters students' intercultural awareness, and improves their communication skills.
eTwinning projects last for any length of time ranging from only a week, to months, up to creating permanent relationships between schools. Schools (both primary and secondary) within the European Union member states can participate in the eTwinning project, in addition to schools from Turkey, Norway and Iceland.
In contrast with other European programmes, such as the Erasmus+ programme, all communication is held through the internet and therefore there is no need for grants. Along the same lines, face-to-face meetings between partner schools are not required, though they are not prohibited and some schools organize face-to-face meetings.
