Considering the Role of Self-Study of Teaching and Teacher Education Practices Research in Transforming Urban Classrooms     

Mary Lynn Hamilton  Stefinee Pinnegar 《Studying Teacher Education》2015,11(2):180-190

We explore the first four articles in this Special Issue of Studying Teacher Education to identify challenges to the self-study of teaching and teacher education practices (S-STEP) methodology, and how this methodology supports the work of teachers and teacher educators working in urban settings. We respond to these articles by identifying strategies and tools that might be used by S-STEP researchers to strengthen the presentation of their work and to explore the challenges to transforming classrooms using this methodology.  相似文献   

Photo-elicitation: reflexivity on method,analysis, and graphic portraits     

Veronica M. Richard  Maria K.E. Lahman 《International Journal of Research & Method in Education》2015,38(1):3-22

In this methodological discussion, the authors detail and reflect on the processes of using photo-elicitation interviewing as a way to align with positive qualitative methodologies, to gain access to participant beliefs and values, and to highlight participant voices through their choices of words and visuals. A review of the literature and an overview of the educational research experiences leading to the discussion are included. Next, the discoveries regarding what is methodologically new and/or valuable concerning this visual method is presented. In the final section, the authors reflexively contemplate aspects of visual methodological processes in an effort to address methodological crossroads of potential and tension including: (1) the potential of decontextualized photos, (2) photos as metaphors of meaning, (3) photos as representations of inherent meaning, (4) participant empowerment, and (5) graphic representation or graphic portraits.  相似文献   

Towards an adolescent friendly methodology: accessing the authentic through collective reflection     

Mary Keeffe  Dorothy Andrews 《International Journal of Research & Method in Education》2015,38(4):357-370

The re-emergence of student voice presents a challenge to schools and researchers to become more responsive to the voice of adolescents in education and in research. However, the poor articulation of the nature of student voice to date is confirmation of the complex and important nature of the personal advocacy and human agency that is involved in all student voice activities. This lack of clarity leads to interpretations of student voice that range in authenticity from token to active and meaningful (Hart, R. 1997. Children's Participation: The Theory and Practice of Involving Young Citizens in Community Development and Environmental Care. Earthscan Publications. London: UNICEF). Researchers who are guided by more traditional methodologies may implement methods that are appropriate for adults yet are not sensitive to the needs and interests of the young person whose perspectives are usually the focus of the research. This research found that while an advocacy and empowerment worldview supports student voice research, adolescents also prefer a methodology that is agentic, socially based, reflective and embodied (Dempster, N., A. Lizzio, M. Keeffe, J. Skinner, and D. Andrews. 2010. “The Contributions of Research Design and Process Facilitation in Accessing Adolescent views of Leadership.” Leading and Managing 16 [2]: 77–89). Adolescent perspectives on research processes and methods are valuable in helping researchers to choose more responsive approaches to sharing understandings with adolescents, so that research designs may be challenging, meaningful and rewarding for all participants.  相似文献   

Methodology in Sports History: Learning from Legal Scholarship?     

Jack Anderson 《国际体育史杂志》2015,32(15):1764-1768

The brief note aims to illustrate how historical context has contributed to my writing on modern sports law and principally through two pieces of work – the first relating to the historical, sui generis origins of the legality of combat or fighting sports, which continues to stretch the boundaries of core principles of criminal law, such as reasonable consent to bodily harm, to their utmost; and second, and more generally, the ‘historicalegal’ influences on the development of modern sport in mid-nineteenth-century Britain. Before that is done, it is best to give some account of research methodologies in legal scholarship and principally as they apply to legal history.  相似文献   

Archives and Historians of Sport     

Martin Johnes 《国际体育史杂志》2015,32(15):1784-1798

Archives and the documents within them are at the heart of the practice of history and the occupational culture of historians. A majority of historical work has been characterized and defined by research in archives of varying kinds. Yet, the material within archives is both partial and political and using it is never straightforward. For historians of sport, the material available in archives can be especially limited but, with some careful reading between the lines, there is still much to learn from and interpret within traditional archives. This paper explores the different kinds of archives and archival material that historians of sport have used and the uses they have been and can be put to. Archives, however, are not static entities and the paper also discusses the impact and implication of digitization processes and programmes to popularize and legitimize traditional archives. Although sport has been seen as one of the ways of diversifying the content and audience of archives, the paper argues that the practical and interpretative challenges historians of sport face in archives are no different to those faced by other historians.  相似文献   

The impact of data reduction on the intra-trial reliability of a typical measure of lower limb musculoskeletal stiffness     

Mark P. Moresi  Elizabeth J. Bradshaw  David A. Greene  Geraldine A. Naughton 《Journal of sports sciences》2015,33(2):180-191

Double-leg repeated jumping tasks are commonly used as measures of lower limb stiffness in exercise science research. Within similar stiffness calculations, variation in data-reduction criteria exists. The impact of these varied data-reduction methods on stiffness measures is unknown. Sixteen adolescent female participants from varied physical activity backgrounds performed 15 self-paced, bent-knee continuous jumps (CJb) on two force plates. Leg stiffness was calculated as the ratio of the peak force and the centre of mass displacement for each contact. Using combinations of criteria based on previous literature, 83 data-reduction methods were applied to the raw data. Data reduction suitability was assessed based on intra-trial reliability, the number of participants excluded and the average contacts excluded. Four data-reduction methods were deemed suitable for use with adolescent female populations, with three consecutive contacts within 1 SD of the average jump frequency considered optimal. The average individual stiffness values were not greatly influenced by the data-reduction method; however, for a single participant, a stiffness change of up to 6 kN · m^?1 (30%) was observed. The role and potential impact of data-reduction methods used to evaluate measures of lower limb stiffness during repeated jumping tasks warrants consideration.  相似文献   

比较教育方法论的历史传统、现代变革及其启示     

王建梁  陈瑶 《高等教育研究学报》2011,34(1):39-42

方法论问题一直是比较教育学界十分关注的问题,这是由于比较教育学科的特殊性所决定的。借鉴主义方法论、民族主义方法论、实证主义方法论是为比较教育方法论的历史传统,20世纪70年代以后则是比较教育方法论的现代变革时期,主要有人文主义方法论、马克思主义方法论、后现代主义方法论。基于方法论问题在比较教育学科的重要性,比较教育学界仍需关注此一问题。  相似文献
