This cross-sectional study aims to determine whether these specific classroom practices are associated with higher student engagement. A secondary goal was to examine whether economically disadvantaged (ED) students in more engaged classrooms scored higher on measures of math, language, and literacy. Researchers collected individual student assessment data in math, language, and literacy for a sample of 407 PreK and K students and conducted day-long observations in their classrooms. In addition to collecting behavioral count data on the focal classroom practices, observers rated students’ engagement across the day. (author abstract)
