The 2017 Global Teacher Prize has been won by Maggie MacDonnell, who teaches in a fly-in Inuit village in the Canadian Artic.

Her victory - which brings with it a prize of $1 million - was announced at the Global Education and Skills Forum in Dubai by an astronaut in the International Space Station, and Ms MacDonnell was congratulated via video message by Canadian prime minister Justin Trudeau.

Ms MacDonnell lives and works in Salluit, an Inuit community in the far north of Quebec which has experienced a number of social problems, including a high number of suicides.

She has helped support several suicidal pupils, set up a life-skills programme for girls, secured funding for hot meals in the community, established a fitness centre and even been a foster parent to some of her own pupils.

Accepting the prize, she said: “The Inuit matter, thank you for bringing global attention to them.”

The winner of the Global Teacher Prize, which is provided by the Varkey Foundation, was announced 80 miles above the Earth by Thomas Pesquet, an astronaut in the International Space Station, who sent a message thanking teachers across the world.

“None of these giant leaps would have been possible without teachers,” he said.

“I’d like to be the first person in history to thank all the world’s teachers from space.”

Mr Trudeau congratulated Ms MacDonnell via a video message in English and French.

A former French and maths teacher, he thanked her “from one teacher to another”.

“I would like to say thank you to every teacher out there,” he said.

“Teachers owe responsibilities to many people - to students, to parents, to the community, the school board.

“But in the end, as all great teachers know - they are responsible to something far greater. They are responsible to the future and to the world that will be shaped by the children they teach”.

The ceremony was shown a video of TV adventurer Bear Grylls delivering the prize by jumping out of a helicopter in a tuxedo above Dubai.
