Among the many prominent thinkers attending the Urban League’s annual conference Thursday, Microsoft founder and philanthropist Bill Gates made his case for focusing on teachers.
One of the nation’s oldest civil rights groups, the Urban League, is holding its annual conference in Boston this week.
Much of the conference focused on education Thursday — specifically, the persistent achievement gap between black and Latino students and their white counterparts.
Gates has been in the education reform game for a while, pouring billions of dollars into scholarships, research and trying to improve public schools. Gates said there have been advances on most other civil rights issues, but not much progress on education.
