Although proponents suggest that universal social-emotional learning (SEL) programs promote academic achievement, few studies have directly tested these outcomes under routine conditions in schools. Forty first-grade classrooms participated in an effectiveness trial in which schools (N = 13) were randomly assigned to implementation of a universal…

This study evaluated the extent to which existing measures met standards for a continuous suite of general outcome measures (GOMs) assessing children's early literacy from preschool through early elementary school. The study assessed 316 children from age 3 years (2 years prekindergarten) through Grade 2, with 8 to 10 measures of language,…

We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

In recent years, states have significantly expanded access to prekindergarten (pre-K), and federal policy makers have proposed funding near-universal access across the country. However, researchers know relatively little about the role of subsequent experiences in prolonging or truncating the persistence of benefits for participants. This study…

Social-emotional learning (SEL) programs have demonstrated positive effects on children's social-emotional, behavioral, and academic outcomes, as well as classroom climate. Some programs also theorize that program impacts on children's outcomes will be partially explained by improvements in classroom social processes, namely classroom emotional…
