100 Women: Students travel through Arctic snow to the 'world's best teacher'
Maggie MacDonnell has been named the "world’s best teacher" - winner of this year's prestigious global teacher prize from the Varkey Foundation.
She teaches in the Arctic where “not every classroom has four walls” and the children have overcome many obstacles just to get to class.
BBC 100 Women names 100 influential and inspirational women around the world every year. In 2017, we're challenging them to tackle four of the biggest problems facing women today - the glass ceiling, female illiteracy, harassment in public spaces and sexism in sport.
