Ambar presses her hand to her forehead as she considers the question on her screen: how many sevens in 91? The ten­year­old has been struggling with it for about a minute when she smiles，"13！" Her tutor responds by posting a large smiling cat picture on her screen-the virtual(虚拟的) meaning of a pat on the back. He is sitting on the other side of the world in an online tutoring centre in India.

Ambar，who attends Pakeman Primary School in London，is one of nearly 4,000 primary school children in Britain that have signed up for weekly one­to­one maths sessions with tutors based in India and Sri Lanka. The lessons，provided by a company called Third Space Learning，are targeted at pupils struggling with maths-particularly those from disadvantaged backgrounds.

From next year，the platform will become one of the first examples of artificial intelligence (AI) software being used to monitor，and ideally improve teaching. Together with some British scientists，the company has analysed around 100,000 hours of audio and written data from its tutorials(辅导课)，with the goal of identifying what makes a good teacher and a successful lesson.
