Instructional and School Effects on Students' Longitudinal Reading and Mathematics Achievements

For this study, Prospects, a data set on schools and students in the United States collected during the early 1990s, was used to examine the effects of instructional and school organizational characteristics on the longitudinal mathematics and reading achievements of students from either a first- or third-grade cohort. Three schooling models were tested using hierarchical linear modeling (HLM) while controlling for parental socioeconomic (SES) status. Factors and variables that represented instructional and school features were derived from teacher and principal responses to survey items. These features had direct and interactive effects on mathematics achievement, supporting both an environmental and interactive model of schooling. Further, schools characterized by teacher collegiality, support for innovation, principal leadership, goal agreement, and community support contained teachers who employed important instructional strategies more effectively, and students who had the highest mathematics gains over the observed period.
