India was once part of the British Empire, but thanks to modern technology and a booming economy, it has turned the tables on its former colonial master. Indian tutors are helping to teach math to British children over high-speed Internet connections. Early results suggest the idea is improving exam results. But not everyone is happy at this “outsourcing” of tutoring.

It’s 3:30, and pupils at Raynham Primary School in London are gathering for their after-school maths lessons.

Five time zones— thousands of kilometers away—their math tutors are also arriving for class. High-speed Internet has made it possible for Indian tutors to teach British pupils in real time. Each pupil gets a dedicated one-to-one online tutor. The students work with activities on their computer screen and wear a headset and microphone to talk to their tutor.

The class teacher, Altus Basson, says he has seen an improvement in results. “There are some children who’ve really rocketed in their results. Children who struggleto focus in class focus a lot better on the laptops. The real advantage is that each child gets a focused activity and a single tutor,” he said.

Such individualized teaching is the core idea of Brightspark Education, the company that provides the online tutoring, says founder Tom Hooper. “Children today feel very confident online; they feel very engaged; they feel very in control. And that's half the battle with education.Give them control, make them feel confident and enjoy their learning and you'll see them start to improve and embrace it," he said.

Raynham Primary School is among the first in Europe to try online tutoring. At between $20 and $25 an hour, it's about half the cost of face-to-face coaching. But some people say an Internet connection is not enough of a connection for teaching and learning. Kevin Courtney is deputy General Secretary of Britain's National Union of Teachers. "We think, there's a really important emotional connection between a teacher and a child whether it's a whole class or whether it's one-to-one. You need that immediacy of feedback and we're not convinced that that can happen across an Internet connection. In one of the wealthiest.countries in the world, we think that we can afford to have teachers with genuine emotional connection there with the children," he said.

Brightspark Education says the online tutoring is used only as an addition to supplement regular teaching. The company says its service does not represent a threat to teachers' jobs in Britain.

Parents say they're very satisfied with the results they've seen. And what about the children?Children: "I love it!"I love it!"I hate maths!" So math--or, as the British call it, maths—is still not everyone's favorite subject even with the latest technology to teach it.
