A well-timed and executed intervention with an under-performing math student can produce very substantive and positive results.  That is the finding in a new study co-authored by Harvard Kennedy School assistant professor Joshua Goodman.  “Intensive Math Instruction and Educational Attainment: Long-Run Impacts of Double-Dose Algebra” is published as part of the National Bureau of Economic Research (NBER) Working Paper series.

The study examines the impact of so-called “double-dose algebra,” in which low-skilled 9th-graders in the Chicago Public Schools (CPS) are assigned to an algebra course that doubled instructional time, altered peer composition and emphasized problem serving skills.
