متن کاملWhen eShadow met ALICE
eShadow is a storytelling tool that can be used from both adults and children in order to create, record, share and watch digital shadow theater plays. It is based on the traditional Greek Shadow Theatre, which has a long history of usage in entertainment and education, particularly pre-school and primary school education. We present our experience from the use of eShadow in the ALICE ALPPs con...
