My research investigates non-formal digital game-based learning (GBL) with refugee children in Bangladesh and Pakistan. Within the scope of the project digital GBL is used to teach early-grade children the basics of numeracy and literacy with tablet computes and selected mobile applications. The children learn to read in their native language, basics of English and basic numeracy without a teacher at their own pace following learning goals that mimic those of the national curriculums of their respective countries.
