Wow! Count on the government not to know about or use **web cams**!
The math tutors in India use them routinely. They can also check work **immediately** through e-mail, scanning, and fax.
Highly experienced teachers, with masters and Ph.D. work for $200 to $600 a month!
Oh boy! Outsourcing education! I hope these tutors are easier to understand than the Indians manning tech help lines...
The link to that you provided me yesterday did not work, so I googled and found a couple of articles: here and here.
It looks as if most of these tutors charge $20 an hour or more, and since costs of living are much less in India, the tutors are making a relative fortune.
The article notes that there is an oversupply of people with math and science degrees in India, and a shortage of qualified math and science teachers in the U.S. (probably because we can make much more money in industry) so maybe it's a good match.
Look for online teaching to be the next big thing to be outsourced offshore
