Teachers' perception of the educational policy is vital to understand the success or failure of the policy's implementation. In this article, we describe the development and use of the Policy Characteristics Scale to measure teachers' perception of a new teacher evaluation policy. An exploratory factor analysis (n = 347) and a confirmative factor analysis (n = 263) revealed a three-factor structure of teachers' perception of the new educational policy: policy's practicality, need, and clarifying function. Our research results indicated that teachers confirm the policy's need. They perceive the reform as clear but they have questions about the policy's implementation. Implications for policy makers and school leaders are discussed. 相似文献

Purpose: The net height in tennis (0.91 m) is approximately 50% of a professional tennis player’s height. Children are also expected to play with this net height, even though it is approximately 70% of the average 10-year-old’s height. This study examined the immediate effect of lowering net height on the performance characteristics of skilled junior tennis players aged 10 years and younger. Method: Sixteen players were matched in 8 pairs of even tennis ability and same sex. Each pair played 25-min singles matches in 4 conditions that varied in net height (0.91 m, 0.78 m, 0.65 m, and 0.52 m). Match-play characteristics were analyzed via video replay. Results: Results showed that lowering the net height to 0.65 m and 0.52 m led to players adopting a more attacking style of play, as evidenced by a significant increase in the number of winners without a commensurate increase in errors and more shots struck inside the baseline. Lower nets also led to a greater percentage of successful first serves. The lowest net (0.52 m), however, reduced rally length significantly and therefore decreased hitting opportunities. Conclusion: These results offer support for equipment scaling to enhance match-play performance for skilled junior tennis players. We propose that current net height recommendations for junior tennis should be revised. 相似文献

Visual search, anticipation and expertise in soccer goalkeepers 总被引:3,自引:3,他引:0
We used a novel methodological approach to examine skill-based differences in anticipation and visual search behaviour during the penalty kick in soccer. Expert and novice goalkeepers were required to move a joystick in response to penalty kicks presented on film. The proportion of penalties saved was assessed, as well as the frequency and time of initiation of joystick corrections. Visual search behaviour was examined using an eye movement registration system. Expert goalkeepers were generally more accurate in predicting the direction of the penalty kick, waited longer before initiating a response and made fewer corrective movements with the joystick. The expert goalkeepers used a more efficient search strategy involving fewer fixations of longer duration to less disparate areas of the display. The novices spent longer fixating on the trunk, arms and hips, whereas the experts found the kicking leg, non-kicking leg and ball areas to be more informative, particularly as the moment of foot-ball contact approached. No differences in visual search behaviour were observed between successful and unsuccessful penalties. The results have implications for improving anticipation skill at penalty kicks. 相似文献

The paper starts from the observation that teacher attrition/retention seems to be a wicked issue: it seems to have strong face validity and a commonsense meaning, but the literature doesn’t provide a clear and distinctive definition. In the first section, the author analyzes the different ways in which the issue of teacher attrition and retention is problematized—in general and educationally—as the basis for a definition: as an educational issue, teacher attrition and retention refers to the need to prevent good teachers from leaving the job for the wrong reasons. Arguing that teacher attrition/retention constitutes both a problem and a challenge, he continues in the second part of the article foregrounding several lessons learned from the research on teacher attrition. A first lesson is related to the central role of social relationships and teachers’ need for social recognition as well as sense of belonging. Secondly, the impact of performativity policies on teacher attrition is discussed. A final lesson looks at teacher attrition and retention from the perspective of career and teachers’ work lives. The conclusion section outlines an agenda for teacher education, teacher induction, and school development to positively deal with the challenge to keep the good teachers in teaching. 相似文献

This article reports on a narrative analysis of one teacher educator’s learning journey in a two-year professional development project. Professional development is conceived of as the complex learning processes resulting from the meaningful interactions between the individual teacher educator and his/her working context. Our analysis indicates that the capacity to manage such interactions contributes strongly to teacher educators’ experience of vulnerability. We analytically describe three strategies (building positive self-esteem, sustaining moral commitment and purpose, and strategical compliance) to cope with this vulnerability and their impact on processes of professional development as well as the outcomes of it. Understanding the role of the working context – and vulnerability as a structural characteristic of that context – in professional development processes adds to existing knowledge of teacher educators’ professional lives and development. 相似文献

The high turnover rates of beginning teachers are an issue of continuing concern in education. However, little is known about the motivational process that encourages beginning teachers to stay in the teaching profession. This study investigated how working conditions (job insecurity, teacher autonomy, collective responsibility, reflective dialogue, and deprivatised practice) and psychological states (teacher self-efficacy and affective commitment) influence turnover intentions. A sample of 272 beginning teachers from 72 Flemish (Belgian) primary schools was recruited for this questionnaire-based study. Path analysis revealed that teacher self-efficacy and affective commitment directly reduced the intention to leave the job. Furthermore, teacher self-efficacy and affective commitment fully mediated the relationships between teacher autonomy and the intention to leave the job and collective responsibility and the intention to leave the job. These findings provide insight into the underlying psychological processes of beginning teachers to leave education. 相似文献

The role of social support in well-being and coping with self-reported stressful events in adolescents 总被引:3,自引:0,他引:3
OBJECTIVE: This study investigated the role that social support plays in well-being and in coping after a stressful event in a group of non-clinical adolescents. Furthermore, this study aimed at replicating the finding that adolescents who reported sexual abuse reported more symptoms and less adequate coping strategies than adolescents who reported another type of stressful event or no stressful episode. METHOD: Eight hundred and twenty adolescents between 12 and 18 years of age filled out questionnaires assessing social support (Social Support Questionnaire, Sarason, Shearin, Pierce, & Sarason, 1987), trauma-related symptoms (Trauma Symptom Checklist for Children, Briere, 1996), behavior problems (Youth Self-Report, Achenbach, 1991), and coping (How I Cope Under Pressure Scale, Ayers, Sandler, West, & Roosa, 1996). RESULTS: 42% of the adolescents reported a stressful experience, and 4.4% reported sexual abuse. Sexually abused adolescents reported more stress-related symptoms and used more avoidance and fewer support-seeking coping strategies than the other adolescents. The main-effect hypothesis of social support was sustained, but social support did not moderate the relation between a stressful event and coping. Yet, a trend was found suggesting that high support from the family was associated with less avoidance coping and more support-seeking in adolescents who reported a non-sexually abusive, stressful event. CONCLUSIONS: Our findings show that a highly perceived availability of social support is directly associated with fewer trauma-related symptoms, especially in adolescents who are non-sexually abused. For adolescents who reported a sexual or another type of stressful event, social support did not play a different role in coping. 相似文献

Teacher perceptions of school culture and their organizational commitment and well-being in a Chinese school 总被引:1,自引:0,他引:1
This study aims to analyze and validate the dimensions and specific features of a school culture in a Chinese context. A sample
of 181 teachers from a Chinese primary and secondary school in Beijing participated in a survey that measures school organizational
cultural characteristics and teacher organizational commitment and well-being as outcomes of school culture. Specific cultural
characteristics of this school and their impact on teacher organizational commitment and well-being were identified. The findings
provide important information for understanding a school culture in the Chinese context. It enriches the theory related to
school culture and the research findings that have been identified in the Western settings. 相似文献

Deaf parents and pediatric cochlear implantation: an exploration of the decision-making process 总被引:1,自引:0,他引:1
Hardonk S Daniels S Desnerck G Loots G Van Hove G Van Kerschaver E Sigurjónsdóttir HB Vanroelen C Louckx F 《American annals of the deaf》2011,156(3):290-304
The study examined factors in deaf parents' decision between cochlear implantation (CI) and traditional hearing aids for their child. The subjects were 6 Flemish children ages 5-9 years with severe/profound congenital hearing loss, with at least 1 deaf parent. The researchers, who conducted thematic content analysis of qualitative data collected through parent interviews, found that with the exception of a family with 1 hearing parent, parents gave priority to Deaf identity, sign language, and ethical issues in deciding between CI and hearing aids. Medical risks were also mentioned. The researchers conclude that the decision-making processes of the parents involved factors that have also been found among hearing parents, as well as aspects that have not been reported to play a role in hearing parents' decision making. A further conclusion is that deaf parents' perspective merits attention in professional practice and empirical research. 相似文献
