Effects of treadmill versus overground soccer match simulations on biomechanical markers of anterior cruciate ligament injury risk in side cutting

This study aimed to investigate whether treadmill versus overground soccer match simulations have similar effects on knee joint mechanics during side cutting. Nineteen male recreational soccer players completed a 45-min treadmill and overground match simulation. Heart rate (HR) and rating of perceived exertion (RPE) were recorded every 5 min. Prior to exercise (time 0 min), at “half-time” (time 45 min) and 15 min post-exercise (time 60 min), participants performed five trials of 45° side-cutting manoeuvres. Knee abduction moments and knee extension angles were analysed using two-way repeated measures analysis of variance (α = 0.05). Physiological responses were significantly greater during the overground (HR 160 ± 7 beats ? min^?1; RPE 15 ± 2) than the treadmill simulation (HR 142 ± 5 beats ? min^?1; RPE 12 ± 2). Knee extension angles significantly increased over time and were more extended at time 60 min compared with time 0 min and time 45 min. No significant differences in knee abduction moments were observed. Although knee abduction moments were not altered over time during both simulations, passive rest during half-time induced changes in knee angles that may have implications for anterior cruciate ligament injury risk.

Education for Sustainability in Scottish Secondary Schools: boundary maintenance or professional reorientation?

This article reports on a study of education for sustainability in Scottish secondary schools. The study was based at the Institute of Education, University of Stirling, and was sponsored (between November 1997 and March 1998) by the Sustainable Schools Partnership, with funding from the Royal Society for the Protection of Birds Scotland, Scottish Natural Heritage and the Worldwide Fund for Nature Scotland and (between April 1998 and July 1998) by the University of Stirling. It comprised three research strands: a trawl of documentary evidence relating to policy and practice within the field of education for sustainability; interviews with key personnel in secondary schools identified as developing good practice in the field of education for sustainability; and a series of discussions with policy makers having a national and/or international perspective on education for sustainability and its development in schools. Although the prime focus was on Scottish schools, each of these strands also covered as a secondary concern relevant work in the other national regions of the UK. Having briefly clarified some issues of definition, the article offers an analysis of the central problem faced by schools (secondary schools in particular) involved in cross‐curriculum developments of this kind. That analysis focuses upon the aspiration of these schools to bring about whole‐school change within an institutional context characterised by strong boundary maintenance. The article then outlines the first of two findings: where education for sustainability is being developed within a secondary school setting, whole‐school change is likely to be conceived as modest modifications to existing structures. The article goes on, however, to outline some of the changing practices within these schools and, in doing so, introduces the second finding: where education for sustainability is being developed within a secondary school setting, whole‐school change is likely to be conceived in terms of a reorientation of professional interest and practice towards the local community and wider community concerns. These two findings, we argue, should be seen neither as complementary nor as existing in creative tension. They point to a school system seriously at odds with itself: pulled by one set of professional and managerial priorities towards piecemeal change within fixed parameters and by a very different set of professional and educational responses towards the reconceptualisa‐tion of teaching and learning and the closer involvement of schools in the local communities. This increased interest in the outward‐looking school community extends to issues of global concern. The article concludes with some thoughts on how this tension might be resolved through a radical reordering of educational priorities in favour of boundary realignment and community participation.

Two conflicting visions of education and their consilience

Over the past two decades, two heavily funded initiatives of the Federal government of Australia have been founded on two very different and seemingly conflicting (if not antithetical) visions of education. The first, the Australian Values Education Program (AVEP, 2003–2010) enshrines what may be called an ‘embedded values’ vision of education; the second, the National Assessments Program-Literacy and Numeracy (NAPLAN, 2008-present) enshrines a ‘performative’ vision. The purpose of this article is to unpack these two seemingly conflicting visions and to argue instead for their possible consilience, bringing together apparently incompatible phenomena to coalesce into a single, more expansive vision of schooling. Against the historical context that gave rise to AVEP and NAPLAN in Australia, the article argues that the visions of education rendered in these abrupt policy shifts are vestiges of a history of dichotomous and dualistic thinking in western educational philosophy. Underpinning this dualism is a fundamental schism between cognition and emotion and a Cartesian separation of mind from body that can no longer be sustained. Our increased understanding of the neural substrates of cognition, the ‘intertwined’ nature of cognition and emotion, combined with a philosophy of mind that does not dissociate propositional knowledge from the disposition of the learner, points to an alternative vision of education. A vision that is thoroughly values embedded, concerned with the educational wellbeing of each child, while also giving value to and prioritising educational performance and achievement, and the intellectual liberation these can offer each and every child.
