This longitudinal study examined gender differences among secondary teacher candidates across three categories of criterion measures: (a) levels of self-confidence in teaching, (b) anticipated sources of professional knowledge, and (c) educational orientations and beliefs. Relative to males, females entered teacher preparation programs with lower levels of confidence in themselves as teachers and higher expectations for what they would gain from education courses and practical experiences related to teaching. Females were also more likely to favor student-centered approaches to instruction and to believe that instructional strategies have limited generalizability. These differences in self-confidence and educational beliefs persisted to program completion.  相似文献

This study explores an under-researched phenomenon of how African Americans communicate about patriotism via ordinary political conversation. We conducted two studies that offer a critical-qualitative analysis of how patriotism is colloquially articulated among African Americans. In study one, focus group interviews were conducted, transcribed, and analyzed using constant comparative method. In study two, we conducted a quantitative content analysis. The findings from study one revealed that there are three relational conceptualizations that help characterize one’s orientation to their nation (i.e., community: subordinate, guardian, and tumultuous). Participants expressed having an attachment to, identification with, and commitment to their communities.  相似文献

Changes to the relations between sport-education and employment labour markets have resulted in the increasing diversity of how academic and vocational skills, knowledge and practices are valued within the micro-level of qualifications. The implications of this are particularly felt by further education (FE) sport-lecturers in the UK, who are required to select, transform and transmit messages from both vocational education policy and the sport-industry sectors. To illustrate the implications of these changing relations, the paper offers insight into the experiences of one FE sport-lecturer, Janet (all names are pseudonyms), who, as part of her professional development, engaged within a process of reflective practice that focused on her pedagogic interactions within a Foundation Degree in Sport Coaching (FdSC). Drawing upon a Bernsteinian informed analysis we illustrate how Janet attempted to use a range of pedagogical strategies to frame the selection, transmission and evaluation of academic skills. This process supported students to begin recognising the value of academic skills and assimilate these with the more established vocational skills within the FdSC qualification. The experiences of Janet are then used as a starting point from which to discuss how the possibilities of change to pedagogic relations within the FdSC may be encouraged, developed and enacted across the vocational sport-education sector. We suggest that institutions and stakeholders responsible for shaping higher education sport-qualifications should consider how lecturers are supported in the framing of pedagogical relations that enable academic skills and practices to be integrated and valued within FdSC curricula.  相似文献

This article looks at the ways in which female football fans in England have responded to and become involved in the cooperative supporters’ trust movement. It examines the history and development of the movement, which offers a new, democratic and equitable way for supporters to become involved in the life of their club, and become part of a new, wider fan community, broader than simple club allegiance. The involvement of respondents in the supporters’ trust movement is explored, profiling the ways in which they have immersed or distanced themselves from the trust concept and community, and comparing their experiences as they have described them in interview. I argue that the trust movement offers the opportunity for supporters to help the game progress in a way that is advantageous to all fans, not just females; and this seems to be an element of the movement that has great appeal to women.  相似文献

The mechanical behavior of cells offers insight into many aspects of their properties. We propose an approach to the mechanical analysis of cells that uses a combination of electromanipulation for stimulus and capacitance for sensing. To demonstrate this approach, polystyrene spheres and yeast cells flowing in a 25 μm×100 μm microfluidic channel were detected by a perpendicular pair of gold thin film electrodes in the channel, spaced 25 μm apart. The presence of cells was detected by capacitance changes between the gold electrodes. The capacitance sensor was a resonant coaxial radio frequency cavity (2.3 GHz) coupled to the electrodes. The presence of yeast cells (Saccharomyces cerevisiae) and polystyrene spheres resulted in capacitance changes of approximately 10 and 100 attoFarad (aF), respectively, with an achieved capacitance resolution of less than 2 aF in a 30 Hz bandwidth. The resolution is better than previously reported in the literature, and the capacitance changes are in agreement with values estimated by finite element simulations. Yeast cells were trapped using dielectrophoretic forces by applying a 3 V signal at 1 MHz between the electrodes. After trapping, the cells were displaced using amplitude and frequency modulated voltages to produce modulated dielectrophoretic forces. Repetitive displacement and relaxation of these cells was observed using both capacitance and video microscopy.  相似文献
