In this paper, we focus on an initiative in England devised to prepare non-mathematics graduates to train as secondary mathematics teachers through a 6-month Mathematics Enhancement Course (MEC) to boost their subject knowledge. The course documentation focuses on the need to develop “understanding mathematics in-depth” in students in order for them to become successful mathematics teachers. We take a poststructural approach, so we are not interested in asking what such an understanding is, about the value of this approach or about the effectiveness of the MECs in developing this understanding in their participants. Instead we explore what positions this discourse of “understanding mathematics in-depth” makes available to MEC students. We do this by looking in detail at the “identity work” of two students, analysing how they use and are used by this discourse to position themselves as future mathematics teachers. In doing so, we show how even benign-looking social practices such as “understanding mathematics in-depth” are implicated in practices of inclusion and exclusion. We show this through detailed readings of interviews with two participants, one of whom fits with the dominant discourses in the MEC and the other who, despite passing the MEC, experiences tensions between her national identity work and MEC discourses. We argue that it is vital to explore “identity work” within teacher education contexts to ensure that becoming a successful mathematics teacher is equally available to all.  相似文献

As in many countries, such as Germany, Turkey, the United States and Japan the history/culture wars of the past two decades have increased public interest in what is taught in schools. This has resulted in rigorous debates in the general community, encouraged and sustained through regular media coverage. Partly as a response to this, History has been designated as a separate subject in the first wave of planning and implementation of the Australian National Curriculum. Two of the reasons for this include first, to recognise the importance of teaching historical skills as a distinct subject; and second there is an ongoing bipartisan political interest in privileging history disciplinary knowledge and content to ensure that national history narratives are taught to students. To contribute meaningfully towards the development and implementation of a National Curriculum, it is important to understand past curriculum constructions, so that the disciplinary knowledge and content of history remains independent, and not subsumed within current (or future) political trends. Based on examples of national history from the Queensland Social Studies syllabus and government endorsed sourcebooks in the lead-up to the 1988 Bicentennial of British colonisation of the Australian continent, this article examines the influence and role of multiculturalism in History teaching in primary schools. Particular attention is paid to Indigenous representations and British heritages, as an example of two groups that have often been represented as binaries to each other throughout Australian history. An analysis of the curriculum materials illuminates the differences between multiculturalism and history—highlighting how the two are merged at the expense of accurate historical knowledge and concepts, particularly in the area of national history. This study will demonstrate that as a result of the infiltration of multiculturalism into history content within the Social Studies curriculum, historical knowledge becomes silenced in the school curriculum – resulting in vague and sometimes historically inaccurate information being presented to students; and the privileging of certain types of multiculturalism.  相似文献

The purpose of this paper is to study the expressive part of game performance in soccer by introducing the concept of theatricality to describe a special form of expression. The aim is to contribute to the understanding of game performance by looking into the appearance, role and value of theatricality. The main argument of the paper is that theatricality can describe an important, but rarely noticed performance aspect, as it provides a unifying concept for expressive distancing in four dimensions of the players’ life-worlds: the subjective, intersubjective, collective and institutional. By explicating the value of this kind of expression in soccer the paper can provide a philosophical basis for including theatricality in performance and development strategies.  相似文献

This text introduces recently completed research on ‘no touch’ sports coaching, by placing it in a broader social context which problematises the way child abuse and child protection (or safeguarding) are conceived and discussed in terms of policy and practice. It also provides a brief indicative summary of the research findings and offers a discussion of moral panic, risk society and worst case thinking, before drawing on Foucault's work on governmentality to offer an explanation of how the current situation arose. The authors suggest that the approach to discussing child abuse, and the guidelines and training stemming from the dominant discourse, for the most part initiated by the NSPCC's Child Protection in Sport Unit, together create an environment in which many coaches and PE teachers are confused and fearful, and consequently unsure of how to be around the children and young people they teach and coach.  相似文献

The purposes of this research were to quantify the kinematics of the lacrosse shot, based on arm dominance and player experience level. Male players (N = 39; 14–30 years; high school [n = 24], collegiate [n = 9], professional [n = 6]), performed overhead shots using dominant and non-dominant sides. Motion was captured using a high-speed, 12-camera optical system and high-speed filming. Body segment rotational velocities and joint angles were determined at key points in the shot cycle from foot contact (0% of shot) to ball release (100% of shot). All players shot with less anterior trunk lean, less transverse shoulder rotation, and slower trunk-shoulder rotational velocities with the non-dominant side than the dominant side (all p < 0.05). Professional players produced crosse angular velocities 21% faster than high school or collegiate players (p < 0.05). Transverse shoulder rotation range of motion on both dominant and non-dominant and trunk rotation sides was highest in the professional players (p < 0.05). These kinematic features enable professional players to produce faster ball speeds than younger players (138 ± 7 km/h vs. 112 ± 15 km/h, respectively; p < 0.05). Less anterior lean or suboptimal rotation sequence could increase proximal shoulder forces that could contribute to injury as in other throwing sports.  相似文献
