Gates Foundation study: Effective teachers key to better education

The Bill & Melinda Gates Foundation spent billions of dollars exploring the idea that smaller high schools might result in higher graduation rates and better test scores. Instead, it found that the key to better education is not necessarily smaller schools but more effective teachers.
Some people might cringe while recounting how much money the foundation spent figuring this out. But the foundation's new CEO, Jeff Raikes, smiles and uses it as an example to explain that the world's wealthiest charity has the money to try things that might fail.
"Almost by definition, good philanthropy means we're going to have to do some risky things, some speculative things to try and see what works and what doesn't," Raikes said Wednesday during an interview with The Associated Press.
Raikes talked of a study of the Los Angeles Unified School District after an initiative to reduce class sizes led to a liberalization of rules on who could be hired to teach. The district found that whether a teacher had a certificate had no effect on student achievement.
Raikes said the district found that putting a great teacher in a low-income school helped students advance a grade and a half in one year. An ineffective teacher in a high-income school held student achievement back to about half a grade of progress in a year. Read more in this Associated Press article on Google's hosted news website.
