Mentoring in context: A comparison of two U.S. programs for beginning teachers   总被引：1，自引：0，他引：1  

Sharon Feiman-Nemser  Michelle B. Parker 《International Journal of Educational Research》1993,19(8)

In reporting on one aspect of a national center's research on teacher education, this chapter examines two U.S. programs in which experienced teachers are expected to play major roles in the induction and socialization of beginning teachers. By exploring connections between what experienced teachers in the two projects do and the organizational and intellectual contexts within which they work, this analysis demonstrates that the contextual conditions of mentoring can lead to striking differences in the definition and enactment of mentoring roles. The final section then relates this comparative study to broader claims about the power of mentoring to improve teaching.  相似文献   

Coptic Language and Identity in Ayyūbid Egypt1     

Kenneth S. Parker 《Al-Masaq: Islam & the Medieval Mediterranean》2013,25(2):222-239

Abstract

In the late Fā?imid and Ayyūbid periods of Egyptian history, Coptic Christians finally addressed the reality that most of their community no longer understood the Coptic language but were, in fact, losing their communal identity and “figures of memory” to Arabisation and even Islamisation. A Coptic-Arabic “Renaissance” ensued whereby Coptic liturgy, theology and history were translated into Arabic, the lingua franca by this time of the Coptic populace. This creative energy extended into the artistic realm – such as iconography and painting – and ultimately strengthened the identity of the Coptic community as their situation became increasingly more restricted.  相似文献

Effect of environmental constraints on multi-segment coordination patterns during the tennis service in expert performers

The aims of this study were to examine the effect of different environmental constraints on kinematic multi-segment coordination patterns during the service and its coordination with service time variability. Ten expert tennis players (Age: 34.1 ± 5.3) volunteered to take part in this study. Participants served 30 times in 3 different conditions: control, target and opposition. The order of conditions was counterbalanced between participants. A wireless 3D motion capture system (STT Co, Spain) was used to measure 7 joint motions, with a 17 degrees of freedom biomechanical model created to capture the entire service action. Results of the principal component analysis showed that 4 synergies were created; however, their roles were changed relative to the perception of the environment. The results of repeated-measures analysis of variance did not show any significant difference on total variance and individual principal components between conditions; however, one synergy pattern significantly predicted the service time variability in both control and opposition conditions. In conclusion, the findings demonstrated that expert performers reduce the joint dimensionality by creating functional synergies in different phases of service and adapt the service action according to the perception of the environment.  相似文献   

Perspectives of applied collaborative sport science research within professional team sports     

James J. Malone  Liam D. Harper  Ben Jones  John Perry  Chris Barnes  Chris Towlson 《European Journal of Sport Science》2019,19(2):147-155

The purpose of the study was to examine the perspectives of both academics and practitioners in relation to forming applied collaborative sport science research within team sports. Ninety-three participants who had previously engaged in collaborative research partnerships within team sports completed an online survey which focused on motivations and barriers for forming collaborations using blinded sliding scale (0–100) and rank order list. Research collaborations were mainly formed to improve the team performance (Academic: 73.6?±?23.3; Practitioner: 84.3?±?16.0; effect size (ES?=?0.54), small). Academics ranked journal articles’ importance significantly higher than practitioners did (Academic: M_rank?=?53.9; Practitioner: 36.0; z?=??3.18, p?=?.001, p?q). However, practitioners rated one-to-one communication as more preferential (Academic: M_rank?=?41.3; Practitioner 56.1; z?=??2.62, p?=?.009, p?q). Some potential barriers were found in terms of staff buy in (Academic: 70.0?±?25.5; Practitioner: 56.8?±?27.3; ES?=?0.50, small) and funding (Academic: 68.0?±?24.9; Practitioner: 67.5?±?28.0; ES?=?0.02, trivial). Both groups revealed low motivation for invasive mechanistic research (Academic: 36.3?±?24.2; Practitioner: 36.4?±?27.5; ES?=?0.01, trivial), with practitioners have a preference towards ‘fast’ type research. There was a general agreement between academics and practitioners for forming research collaborations. Some potential barriers still exist (e.g. staff buy in and funding), with practitioners preferring ‘fast’ informal research dissemination compared to the ‘slow’ quality control approach of academics.  相似文献
