The Recruitment of New Teachers from Minority Ethnic Groups

This article reports on part of a larger, ongoing two-year investigation supported by the Teacher Training Agency into the recruitment of new teachers from minority ethnic backgrounds via Postgraduate Certificate in Education (PGCE) courses in England. The authors focus here on interviews with admissions tutors, course directors and other senior staff at teacher training institutions. The interviews revealed differences between institutions in the measures taken to attract minority ethnic students. The research indicates a need for much clearer guidelines for admissions tutors on the issues surrounding the question of 'positive action' on the recruitment of new teachers from minority ethnic groups.  相似文献   

Linear Acceleration Measurement Utilizing Inter-Instrument Synchronization: A Comparison between Accelerometers and Motion-Based Tracking Approaches     

Andrew J. Callaway  Jon E. Cobb 《Measurement in physical education and exercise science》2013,17(2):151-163

Where as video cameras are a reliable and established technology for the measurement of kinematic parameters, accelerometers are increasingly being employed for this type of measurement due to their ease of use, performance, and comparatively low cost. However, the majority of accelerometer-based studies involve a single channel due to the difficulty associated with synchronizing multiple accelerometer channels. The authors of this article outline a method to synchronize multiple accelerometers using a maxima detection method. Results are presented that demonstrate the effectiveness of the new synchronization method with 52 of 54 recorded data sets showing no time lag error and two tests showing an error of .04 sec. Inter-instrument and instrument-video correlations are all greater than r = .94 (p < .01), with inter-instrument precision (Root Mean Square Error; RMSE) ≈ .1ms^?2, demonstrating the efficacy of the technique. In conclusion, the new technique offers a robust solution, giving further support to the movement toward wider adoption of accelerometer-based performance measurement systems in sports science.  相似文献   

Estimating propulsive forces in swimming from three‐dimensional kinematic data     

Carl J. Payton  Roger M. Bartlett 《Journal of sports sciences》2013,31(6):447-454

Propulsive forces are important determinants of swimming performance. The aim of this study was to quantify the measurement error (uncertainty) in propulsive forces calculated from kinematic data. Ten operators digitized underwater video recordings of a breaststroke swimmer's right arm action. Four landmarks on the hand were digitized at 50 Hz and their three‐dimensional coordinates obtained using a DLT algorithm. Two angles (α and ψ) defining the orientation of the hand relative to the fluid flow were calculated following the procedures of Schleihauf et al. (1983). The hydrodynamic force acting on the hand (F _R) was calculated using the force coefficients of Schleihauf (1979). Errors in single measurements of hand speed, α and ψ were estimated for each video field analysed. Errors in α and ψ led to average errors in the lift and drag coefficients of 27 and 20% respectively, which, when combined with an average hand speed error of 6%, produced an average error in F _R of 26%. Each of these errors was reduced by a factor of √10 when the mean of 10 measurements was used to calculate F _R . Researchers should report both the estimated errors in their hydrodynamic data and the procedures used to reduce them.  相似文献   

Usāma Ibn munqidh's book of the staff: autobiographical and historical excerpts     

Paul M. Cobb 《Al-Masaq: Islam & the Medieval Mediterranean》2005,17(1):109-123

Usāma ibn Munqidh (d. 584/1188) is best known to historians for his “memoirs” entitled Kitāb al-i‘tibār, which provides a very personal and detailed window into the world of an aristocratic Syrian Muslim in the period of the Crusades. But historians have almost completely ignored a lesser-known work by Usāma called Kitāb al–‘a.(s)ā, or The Book of the Staff. This anthology consists mostly of poetic excerpts relating to walking-sticks and staves, but, scattered throughout, it also contains a handful of narrative anecdotes about Usāma and his times very much akin to the material found in his “memoirs”: tales of miracles, of encounters with the Franks, of Usāma's family, and the courts of the amirs and atabegs of his day. This article presents these extracts translated into English for the first time, with commentary, in the hope that the Book of the Staff will attract the attention of historians that it deserves.  相似文献   

“Because uni is totally different than what you do at TAFE”: protective strategies and provisions for diploma students traversing their first professional experience placement at university     

Fay Hadley  Rebecca Andrews 《Asia-Pacific Journal of Teacher Education》2015,43(3):262-276

Students who enrol in a Bachelor of Education (Early Childhood Education) at the Institute of Early Childhood, Macquarie University, with a Diploma in Children’s Services attained from a Technical and Further Education (TAFE) institution or a Registered Training Organisation (RTO) often experience challenges in their first professional experience unit. Utilising a phenomenological approach to understand the students’ previous knowledge and experiences as they navigated through their first professional experience unit, this qualitative study identified factors including institutional structures and course content as challenging to the diploma student. To ensure diploma students can successfully transition to and participate in their first professional experience unit at university, all stakeholders including the university, the academics teaching the students, and the students themselves need to commit to a multilevel support programme. Key findings from this study support the previous research on this student cohort.  相似文献

To succeed or not to succeed: A critical review of issues in learned helplessness     

Sandra Fay Mark 《Contemporary educational psychology》1983,8(1):1-19

A critical analysis of theoretical and methodological issues in learned helplessness is presented. Researchers have tended to focus upon learned helplessness as a behavioral trait independent of contextual conditions. Learned helplessness has been studied exclusively in achievement settings using achievement tasks, perceived as maladaptive behavior requiring some intervention strategy or retraining program. It has not been studied as an adaptive response to situational demands. It is the purpose of this paper to analyze the theoretical backgrounds and methodological limitations of much of the research in learned helplessness and to suggest new directions and implications for education.  相似文献
