Bill Gates' School Crusade: The Microsoft founder's foundation is betting billions that a business approach can work wonders in the classroom

Bloomberg Businessweek reports on Bill Gates' ideas on education and what his foundation wants :

It has since shifted its considerable weight behind an emerging consensus—shared by U.S. Education Secretary and Gates ally Arne Duncan—that quality of teaching affects student performance and that increasing achievement is as simple as removing bad teachers, identifying good ones, and rewarding them with more money. On this theory, Gates is investing $290 million over seven years in the Tampa, Memphis, and Pittsburgh school districts as well as a charter school consortium in Los Angeles. The largest chunk of money, $100 million, will go to Tampa's Hillsborough County school district, the eighth-largest in the U.S., with 192,000 students and 15,000 teachers. These carefully selected programs, which will favor or penalize teachers depending on whether students make larger or smaller gains than their test scores in prior years would have predicted, are intended as models that, if proven successful, can be rolled out nationwide.

The Gates agenda is an intellectual cousin of the Bush Administration's 2002 No Child Left Behind law, which required all public schools—though not individual teachers—to make "adequate yearly progress" on student test scores. Some opponents of No Child Left Behind questioned its faith in data; are scores too narrow a gauge of how well kids are learning? Gates sees nothing wrong in relying on quantitative metrics. "Every profession has to have some form of measurement," he said in a late June interview with Bloomberg Businessweek. "Tuning that, making sure it's fair, getting the teachers so they're enthused about it" are the keys.
