"What creates wide gaps in achievement in math (and many other subjects) in minority students is lower expectations for success." And then it links to http://www.ascd.org/publications/educational-leadership/feb04/vol61/num05/-Closing-the-Minority-Achievement-Gap-in-Math.aspx http://www.ascd.org/publications/educational-leadership/feb0... But to attribute the entire discrepancy to lower expectations baffles me. How is it that so many people are so confident in their various contradictory theories surrounding educational outcomes?
