A synthesis of studies searching for school factors: implications for theory and research.

This paper reports the results of a meta-analysis in which the dynamic model of educational effectiveness is used as a framework to search for school factors associated with student achievement. The methods and results of a synthesis of 67 studies are presented. Findings reveal that effective schools are able to develop policies and take actions in order to improve their teaching practice and learning environment. Factors excluded from the dynamic model were found to be only weakly associated with outcomes. Implications for research on school effectiveness and for improvement of practice are drawn. It is illustrated that this approach of conducting meta-analysis helps us interpret the findings by providing support to the validity of the dynamic model and suggestions for its further development.
