Personal variables affecting the perspectives of head‐teachers and teachers towards teacher participation in school decision‐making

The article reviews research which has taken place relating to the influence of certain biographical factors on head‐teacher and teacher perspectives on who should take decisions within schools. The particular biographical factors which are considered are status, sex, age, length of experience and school size. Each is examined independently and shown to have some influence though existing research does not always agree on the type or extent of this influence. The article concludes by stating that whatever this influence might be, it is only one small aspect of the complex decision‐making process.     

Using Data in Leadership for Learning

School leaders are faced with the daunting task of anticipating the future and making conscious adaptations to their practices, in order to keep up and to be responsive to the environment. To succeed in a rapidly changing and increasingly complex world, it is vital that schools grow, develop, adapt and take charge of change so that they can control their own futures.This paper will examine the tension that exists for school leaders in relation to data about their schools and their students, arguing that the explicit connections between data and large-scale reforms make it impossible to avoid a critical approach to data, drawing on research in Ontario and Manitoba in Canada, and examining parallels with evidence from research in England, to highlight the challenges involved in using data effectively in different political contexts and mandated policies on the uses of data.     

Educational Research and Policy: Epistemological Considerations

This article is centrally concerned with the sort of knowledge that can and should inform educational policy—and it treats this as an epistemological question. It distinguishes this question from the more extensively explored question of what sort of knowledge in what form policy‐makers do in fact commonly take into account. The article examines the logical and rhetorical character of policy and the components of policy decisions and argues that policy demands a much wider range of information than research typically provides. Either the research task or commission has to be substantially extended or the gap will be filled by information or thinking that is not derived from research. One of the gaps between research of an empirical kind and policy is the normative gap. In the final section the article points to the inescapably normative character of educational policy. Of course the values that inform policy can be investigated empirically, but this kind of enquiry cannot tell us what we should do. There is a role for research/scholarship and more rather than less intelligent and critical argumentation in addressing these normative questions as well as the empirical questions that underpin policy.     

Upper extremity augmentation of lower extremity kinetics during countermovement vertical jumps

Twenty-five volleyball players (14 males, 11 females) were videotaped (60Hz) performing countermovement vertical jumps with and without an arm swing. Ground reaction force and video-based coordinate data were collected simultaneously. The resultant joint force and torque at the hip, knee, ankle and shoulder for two trials per subject per condition were computed and normalized. Average kinematic, resultant joint force and torque data were compared using repeated-measures analysis of variance. Larger values were recorded for the vertical velocity of the centre of mass at take-off in the jumps with (mean 2.75, s=0.3m.s-1) versus without (mean 2.44, s= 0.23m.s-1) an arm swing. The jumps with no arm swing produced larger torques at the hip during the first third of the propulsive phase (from zero to maximum vertical velocity of the centre of mass). During the final two-thirds of the propulsive phase, the arm swing augmented hip extensor torques by slowing the rate of trunk extension and placing the hip extensor muscles in slower concentric conditions that favoured the generation of larger forces and resultant joint torques. During the first two-thirds ofthe propulsive phase, knee extensor torque increased by 28% in the jumps with an arm swing, but maintained a relatively constant magnitude in the jumps with no arm swing.
