Drawing on both detailed case studies and large - scale quantitative analysis, the authors show that the majority of school variables, considered individually, have at most a small impact on learning. (wallacefoundation.org)
These studies clearly demonstrate that strong school library programs help all students do better academically, even when other school variables are considered. (ilovelibraries.org)
New empirical work, using better data (e.g., that enable researchers to estimate the relative impact of factors affecting student achievement growth from year to year) and more - sophisticated statistical techniques has, in broad terms, reinforced the Coleman Report conclusion that teacher quality is the most important schooling variable.
