Though there wasn't a lot of detail on exactly how the money would be spent, Gates, a believer in using big data to solve problems, repeatedly said foundation grants given to schools as part of this new effort would be driven by data. "Each [school] network will be backed by a team of education experts skilled in continuous improvement, coaching and data collection and analysis," he said, an emphasis that is bound to worry critics already concerned about the amount of student data already collected and the way it is used for high-stakes decisions. In 2014, a $100 million student data collection project funded by the Gates foundation collapsed amid criticism that it couldn't adequately protect information collected on children.
"In his speech, Gates said that education philanthropy was difficult, in part because it is easy to 'fool yourself' about what works and whether it can be easily scaled," according to the article. It also argues that big spending on education by Gates and others "has raised questions about whether American democracy is well-served by wealthy people pouring so much money into pet education projects -- regardless of whether they are grounded in research -- that public policy and funding follow."
By 2011 the Gates' foundation had already spent $5 billion on education projects -- and admitted that "it hasn't led to significant improvements."
