Dr Mary Ashun is CEO of Ghana International School, one of West Africa's leading international schools, where she's spent over 12 years building what she calls "talent architecture" - pipelines to grow Ghanaian teachers and leaders rather than relying on expat hires. A scientist turned educator with degrees from London, Toronto and Buffalo, she's also a Klingenstein Fellow from Columbia and an author of children's books. In this episode, Mary shares the remarkable story of a teacher who swims through crocodile-infested waters to reach his classroom, explains why England poaching 2,300 Ghanaian teachers while offering education aid feels like a contradiction and delivers a powerful challenge: with Africa set to be the demographic centre of gravity, a curriculum where just 6% of texts are African is failing our children.
