Schoolchildren chatted with youngsters in Italy, Poland and Slovenia.
The call – which was projected on a giant screen – was part of the Steeton pupils’ work on the Second World War The children exchanged information about how the war affected their country, and each school sang a song from the war.
The youngsters have also written blogs about their research.
The children in Slovenia were joined on the call by a former teacher who had been imprisoned in a Nazi labour camp in German-occupied Poland during the war.
Teacher Diana Linford was the project co-ordinator at Steeton Primary and is an eTwinning Ambassador for the Yorkshire region.
She said: “Both children and teachers benefit enormously from working with schools in other countries.
“It helps to give a depth and sense of perspective.”
