This paper presents a new heuristic device for the analysis of educational policy. Through an examination of the Evaluative State and the work of Brian Fay, the paper considers the way in which educational policy is subject to rational and linear forms of policy action and implementation. To counter this, positioning theory is deployed to consider the way in which we are produced both by discourse and the language of the ‘moment’ in discursive acts. Using the work of Gee, the paper contends that policy texts and policy Discourse ‘themselves form policy, that is, they position policy-explanation and policy-framing within the bounds of the institution and so give policy form’. Problematically, such mechanisms may succumb to the ‘death of subject’ and accordingly I offer a third method by which we might conceive of education policy: the discursively produced position call. Subsequently, I propose a tri-partite theory for the examination and understanding of policy: policy-explaining, the production of policy texts; policy-framing, the ways in which all can be positioned by texts and Discourse to produce the meanings imbued upon policy; and, policy-forming, the impact of moment-by-moment conversational acts for their production of the policy text itself, that is, the ways in which policy is locally formed rather than locally mediated.  相似文献

This article presents a new classroom observation scale that was developed to examine the differential learning activities and experiences of gifted children educated in regular classroom settings. The Differentiated Classroom Observation Scale (DCOS) is presented in total, with clarification of the coding practices and strategies. Although the DCOS was developed to examine the impact of differentiated classroom practices for gifted children, it is expected that the scale could be used for observing the educational experiences of any identifiable group of children. Reflections on the benefits offered by the DCOS that are not available with existing measures are provided, and include (a) the ability to contrast the educational experiences of two groups of learners; (b) documentation of a variety of educational factors including pedagogy, student engagement, and level of cognitive activity; and (c) preservation of contextual factors for deeper investigation through a database‐driven record keeping system that maintains disaggregated data from a series of short observational segments.  相似文献

ABSTRACT

Ageism refers to discrimination against individuals based on age, while aging anxiety is defined as fear about getting older. We were interested in whether ageism and aging anxiety had distinct correlates among young adults. The purpose of this study was to explore the effects that knowledge of aging, contact with older adults, fear of death, and optimism have on ageism and aging anxiety in young adults (N = 623). Knowledge of aging and contact with older adults were associated with lower ageism. Aging anxiety was associated with greater fear of death and lower optimism. Results indicate that the positive effects of contact and knowledge on the attitudes of young adults toward the older adult population. Increased education on the aging process and improving quality of contact with older adults could help reduce ageism and ageing anxiety.  相似文献

One of the central narratives of the 1908 Olympic Games is the intense Anglo-American acrimony which culminated in the nadir of their sporting relations. One of the major controversies involved the 400 metres final which featured Halswelle, a British athlete, and three Americans – Carpenter, Robbins and Taylor. The final was declared void after Carpenter obstructed Halswelle and was disqualified. In protest the Americans withdrew Robbins and Taylor from the re-run and Halswelle won the gold medal unopposed. This paper explores the 400 metres final from the perspective of the British athlete Wyndham Halswelle utilising his diaries, photo albums, scrapbooks and the papers of his elder brother, Gordon. Serendipitously, the continual digitisation of newspapers also gave further insight into allegations of illegal team tactics by Carpenter and Robbins in the initial race. The article then further exploits these resources to develop a case study of Halswelle as an elite early-twentieth-century British amateur athlete. Differences in ideas of the amateur athlete ideal are often identified as an underpinning cause of international squabbling at the IV Olympiad and may have led to Halswelle’s decision to retire after the games at the age of 26 while still improving his performances.  相似文献

Exercise has been demonstrated to have considerable effects upon haemostasis, with activation dependent upon the duration and intensity of the exercise bout. In addition, markers of coagulation and fibrinolysis have been shown to possess circadian rhythms, peaking within the morning (0600–1200?h). Therefore, the time of day in which exercise is performed may influence the activation of the coagulation and fibrinolytic systems. This study aimed to examine coagulation and fibrinolytic responses to short-duration high-intensity exercise when completed at different times of the day. Fifteen male cyclists (VO2max: 60.3?±?8.1?ml?kg?1?min?1) completed a 4-km cycling time trial (TT) on five separate occasions at 0830, 1130, 1430, 1730 and 2030. Venous blood samples were obtained pre- and immediately post-exercise, and analysed for tissue factor (TF), tissue factor pathway inhibitor (TFPI), thrombin–anti-thrombin complexes (TAT) and D-Dimer. Exercise significantly increased plasma concentrations of TF (p?p?p?p?p?=?.004) and TFPI (p?=?.031), with 0830 greater than 1730 (p .001), while 1730 was less than 2030?h (p?=?.008), respectively. There was no significant effect of time of day for TAT (p?=?.364) and D-Dimer (p?=?.228). Power output, TT time and heart rate were not significantly different between TTs (p?>?.05); however, percentage VO2max was greater at 1730 when compared to 2030 (p?=?.04). Due to a time-of-day effect present within TF, peaking at 0830, caution should be applied when prescribing short-duration high-intensity exercise bout within the morning in populations predisposed to hypercoagulability.  相似文献

Nearly 700 US journalism and mass communication faculty (all teaching personnel) reported their perceptions of student email use via a web‐based survey. This nationwide study focused on the content of email sent by faculty to students, email’s effectiveness, and email’s effect on student learning. Comparisons were made based on faculty gender, rank, age, and ethnicity. Findings suggest that despite statistical differences, when gender, rank, age, or ethnicity are considered, faculty are not in the habit of sending course materials like syllabi, project instructions, and lecture notes to students personally via email. Moreover, faculty tend to find favor with email communication and its effectiveness as a tool of teaching. The results of this survey coupled with previous research by the authors and other scholars suggest faculty ought to embrace the technology and develop positive ways to incorporate email, as well as other technology, into the educational process.  相似文献

This article presents the findings of an international collaborative investigation into preservice teachers’ views on the nature of scientific knowledge development with respect to six elements: observations and inferences, tentativeness, scientific theories and laws, social and cultural embeddedness, creativity and imagination, and scientific methods. A total of 640 preservice teachers, 209 from the United States, 212 from China, and 219 from Turkey, participated in the study. The survey “Student Understanding of Science and Scientific Inquiry (SUSSI)”, having a blend of Likert-type items and related open-ended questions, was used to gain a fuller understanding of the preservice teachers’ views of the nature of scientific knowledge development. Across the three countries, the participants demonstrated better understanding of the tentative NOS aspect but less understanding of the nature of and relationship between scientific theories and scientific laws. The Chinese sample scored highest on five of the six Likert sub-scales, the USA sample demonstrated more informed views on observation and inference, and the Turkish preservice teachers possessed relatively more traditional views in all six NOS aspects. Conclusions and limitations of the present study as well as implications and recommendations for future studies, are also discussed.  相似文献
