The significance of the classroom effect in primary schools: An application of creemers' comprehensive model of educational effectiveness

Abstract

This article presents findings of an attempt to test Creemers' model of educational effectiveness by using data derived from an evaluation study in Mathematics in which 30 schools, 56 classes and 1,051 pupils of the last year of primary school of Cyprus participated. More specifically, we examine whether the pupil, classroom and school variables show the expected effects on pupils' achievement in Mathematics. Research data concerned with pupils' achievement in Mathematics were collected by using two different forms of assessment (external assessment and teacher's assessment). Questionnaires were administered to pupils and teachers in order to collect data about most of the variables included in Creemers' model. The findings support the main assumptions of the model. The influences on pupil achievement are multilevel and the net effect of classrooms was higher than that of schools. Implications for the development of research on school effectiveness are drawn.
