Principals and student outcomes: Evidence from U.S. high schools

This paper presents an empirical analysis of the effects of principals on public high school students' academic achievement, using High School and Beyond. Despite policy relevance, previous qualitative and quantitative research provides little systematic evidence on principal effects, at least for high schools. Principal characteristics and variables designed to capture less tangible aspects of the principal's role are included in educational production functions. The results suggest principals do have a measurable impact on student achievement, through the selection of teachers and setting of academically oriented school goals.     

Grammar for Writing? A Critical Review of Empirical Evidence

Governmental concerns about primary children's performance in writing in the Standard Assessment Tasks (SATs) have resulted in the 'Grammar for Writing' Initiative. This resource and the associated in-service training is intended to raise standards in the teaching of writing. The article reviews SATs reports, inspection reports and research evidence in order to address the question: to what extent can this development be justified by empirical evidence on the teaching of grammar? It is concluded that the initiative is not supported by research evidence and that changes will need to be made to English curriculum policy and pedagogy if children's writing is to further improve.     

Imaginary subjects: school science,indigenous students,and knowledge–power relations

The perspectives of indigenous science learners in developed nations offer an important but frequently overlooked dimension to debates about the nature of science, the science curriculum, and calls from educators to make school science more culturally responsive or ‘relevant’ to students from indigenous or minority groups. In this paper the findings of a study conducted with indigenous Maori children between the ages of 10 and 12 years are discussed. The purpose of the study was to examine the ways that indigenous children in an urban school environment in New Zealand position themselves in relation to school science. Drawing on the work of Basil Bernstein, we argue that although the interplay between emergent cultural identity narratives and the formation of ‘science selves’ is not as yet fully understood, it carries the potential to open a rich seam of learning for indigenous children.
