In the Boston Globe last week, I had an op-ed about what I call the “graduation gap” in Massachusetts. Nearly nine out of ten students earn a high school diploma, while less than half of the state’s 10th graders are proficient in math.

States are obscuring student math performance

The Center on Reinventing Public Education’s new State of the American Student 2025 report delivers a sobering verdict: most states are failing to give parents and the public a clear view of how students are doing in math.

How Parents Support Math at Home

When my dad took us on long road trips as a kid, he would give my brother and I what he called “can problems.” Iowa used to have, and still has, a bottle deposit law where each returned soda can or bottle was worth a nickel.

Math Gaps Emerge Early. Students Deserve Early Interventions

Did you know that 3rd grade reading scores are highly predictive of later-life outcomes? It’s true. My favorite paper on this comes from Dan Goldhaber, Malcolm Wolff, and Tim Daly, who looked at how accurate early measures of achievement are in predicting longer-term academic outcomes. In a 2021 paper, they used data from North Carolina, Massachusetts […]

The Rise and Fall of 8th Grade Algebra

The Rise and Fall of 8th Grade Algebra

Algebra is a gateway toward more advanced mathematics courses, and passing the course in 8th grade is a strong predictor of future college success. All students can be math solvers, but students need opportunities to prove it. Unfortunately, schools have been limiting opportunities for students to take Algebra in 8th grade, and it shows up in a remarkable graph of […]
