We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...

One of the most controversial educational practices among American public schools is the use of ability-tracking of students. Over the years, tracking has received harsh criticism. In fact, policymakers have launched initiatives to discourage tracking across the nation, and started recommending...

Success or failure in freshman math has long been thought to have a strong impact on subsequent high school outcomes. We study an intensive math instruction policy in which students scoring below average on an 8th grade exam were assigned in 9th grade to an algebra course that doubled...
