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

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

Electroosmotic flow (EOF) with two or more fluids is commonly encountered in various microfluidics applications. However, no investigation has hitherto been conducted to investigate the hysteretic or flow direction-dependent behavior during the displacement flow of solutions with dissimilar ionic species. In this investigation, electroosmotic displacement flow involving dissimilar ionic solutions was studied experimentally through a current monitoring method and numerically through finite element simulations. The flow hysteresis can be characterized by the turning and displacement times; turning time refers to the abrupt gradient change of current-time curve while displacement time is the time for one solution to completely displace the other solution. Both experimental and simulation results illustrate that the turning and displacement times for a particular solution pair can be directional-dependent, indicating that the flow conditions in the microchannel are not the same in the two different flow directions. The mechanics of EOF hysteresis was elucidated through the theoretical model which includes the ionic mobility of each species, a major governing parameter. Two distinct mechanics have been identified as the causes for the EOF hysteresis involving dissimilar ionic solutions: the widening/sharpening effect of interfacial region between the two solutions and the difference in ion concentration distributions (and thus average zeta potentials) in different flow directions. The outcome of this investigation contributes to the fundamental understanding of flow behavior in microfluidic systems involving solution pair with dissimilar ionic species. 相似文献

The purpose of this investigation was to measure the interface pressure exerted by lower body sports compression garments, in order to assess the effect of garment type, size and posture in athletes. Twelve national-level boxers were fitted with sports compression garments (tights and leggings), each in three different sizes (undersized, recommended size and oversized). Interface pressure was assessed across six landmarks on the lower limb (ranging from medial malleolus to upper thigh) as athletes assumed sitting, standing and supine postures. Sports compression leggings exerted a significantly higher mean pressure than sports compression tights (P < 0.001). Oversized tights applied significantly less pressure than manufacturer-recommended size or undersized tights (P < 0.001), yet no significant differences were apparent between different-sized leggings. Standing posture resulted in significantly higher mean pressure application than a seated posture for both tights and leggings (P < 0.001 and P = 0.002, respectively). Pressure was different across landmarks, with analyses revealing a pressure profile that was neither strictly graduated nor progressive in nature. The pressure applied by sports compression garments is significantly affected by garment type, size and posture assumed by the wearer. 相似文献

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined. 相似文献
