| After more than 30 years of research on schools and classrooms, a science of education has begun to emerge. Although there is no silver bullet that guarantees that every student will be successful, now more than ever research provides guidance about the characteristics of effective schools and effective teachers that, if followed, can help maximize school performance. This brief is based on McREL's meta-analyses of quantitative research on teacher, school, and leadership practices. Meta-analysis, or a statistical analysis of a collection of individual studies, can be a compelling research method for determining what really works in education. Through its meta-analyses, McREL has identified a number of variables that influence student achievement. This brief offers suggestions for implementing policies and practices that can positively impact these variables. |
