This extensive report proposes a long-term strategic research and development program that focuses on raising mathematical proficiency and removing inequalities. It may be of particular interest and usefulness to those projects involved in K-12 math reform.
Abstract: "This report grew out of concerns about the weak levels of mathematical proficiency among U.S. citizens and the inequities in the achievement of students of different ethnic, cultural, and social groups. Debates concerning the value of specific curricula, requirements for teacher knowledge, and standards that students should meet are poorly informed because research evidence is lacking. ...The program addresses issues directly related to teaching and learning by focusing on three domains: developing teachers' mathematical knowledge for teaching; teaching and learning mathematical practices--the mathematical know-how that characterizes expertise in learning and using mathematics; and teaching and learning algebra in grades K-12."
