Mr Raab is keen to support more Scottish teachers and children aged seven to 14 to learn about the wider world through the Connecting Classrooms through Global Learning (CCGL) programme.
It puts Scottish pupils in touch with children of the same age in 29 developing countries across Africa, the Middle East and Asia via video link.
Funding grants will also be available so that teachers can visit their partner schools face-to-face, once coronavirus travel restrictions are eased.
The £37million programme, run by the British Council and co-funded by the Foreign, Commonwealth & Development Office (FCDO), has already helped over 2,000 British schools.
The pupils discuss global issues such as climate change, gender equality and sustainability.
Holy Rood High School, Broughton Primary School and St Mary’s RC Primary School are amongst 18 Edinburgh schools already involved in Connecting Classrooms partnerships.
