There is, or at least was until recently, an idea out there in America that every child deserves a great teacher. But that isn’t possible, because not every worker is great. According to FY 2012 Census Bureau data, U.S. public schools had a total 4,659,517 full time equivalent instructional employees for 48,212,483 students, a ratio of 10.3 to one. There may not be 4.7 million “great” workers in the entire country, depending on how strictly one defines greatness, let alone that many available just for public education. So you’ll have some great teachers, some good teachers, some average teachers, and some below average teachers. And thanks to low pay in some areas of the U.S., and union power in other areas, lots of bad teachers the schools can’t get rid of.
There is a way, however, that every child could have access to great teachers. Over the internet. Just as information technology allows the best entertainers and game designers to serve millions of people at a time at a very low incremental per-person cost, so that same technology could allow millions of children access to the best instruction, exercises and practice, homework and tests. In a format that was available on demand at any time. With different teaching styles that might work for different students. And the possibility of each child working at their own pace, rather than being held back by or trying to keep up with the average for a class, and with lots of extra practice for skills they and yet to master. All that would be missing is the possibility of a trained teacher working with an individual child on something they were having trouble with. But that is something the public education doesn’t provide either – despite that student to instructional employee ratio of 10.3 to 1.
