This article explores how the post 9/11 climate has impacted Muslim-Canadians' information practices, including their uses of various information sources, and their attitudes and perceptions regarding their information rights in a post 9/11 world. A survey was conducted in 2004-2005 with 120 participants and supplemented by in-depth interviews. The population consisted of Muslim students enrolled in post-secondary institutions in Toronto, Ontario. The findings highlight Muslims' malaise in a post 9/11 environment; the deep mistrust they hold vis-à-vis the media; the importance they give to media and information literacy skills for all; as well as a call for increased introspection inside the Muslim community(ies). The study contributes to shedding light on a community that has often being talked and written about but not often heard. By soliciting Muslim individuals' perspectives, we enable them to voice their opinions about how the 9/11 events impacted on their lives and how their information practices inform their experiences.  相似文献

This study examined perceptions of the learning environment among different subgroups of students within science classes. The purpose was to identify variables that can promote effective science learning environments for all students. Specifically, comparisons were made between the perceptions of male and female students and of black and white students within the same classes. In addition, perceptions of the learning environment were compared for students in classes taught by male and female teachers as well as black and white teachers. A diverse sample of over 1800 ninth-grade science students who attended 13 different high schools across the country participated in this study. Results indicated there were differences between subgroups of students in the same classes concerning perceptions of involvement and difficulty of the class. The implications of these results for science teaching are discussed, as well as recommendations for future science learning environment research. J Res Sci Teach 34: 791–804, 1997.  相似文献

Project SEARCH (Science Education and Research for CHildren) is an outreach program designed to teach science and to foster positive attitudes toward science. Through the project, university science students bring activity-based learning, plus materials and content expertise, to local classrooms and after-school programs. Using observations, surveys, and interviews, we examined the experiences of these students as curriculum planners, teachers, and role models for the children. We found that teachers value the enthusiasm and the resources provided by the SEARCH students. Children were engaged in the activities and looked forward to the students' visits. They also see them as positive and diverse models for the role of scientist. But there were often problems in the areas of preparation, scheduling, and communication, and the classroom activities often replicated traditional didactic lessons. The SEARCH experience highlights both the value of providing diverse and challenging experiences for children, and the need for dialogue and reflection on those experiences. Despite several concerns, the SEARCH model is one that deserves expansion and further study as it is extended into new settings. © 1997 John Wiley & Sons, Inc.

The associations among lower extremity functional performance and quality of life in obese youth are unknown. The aims of this study were to compare lower extremity strength, lower extremity functional performance, and health related quality of life between obese and healthy-weight youth and evaluate the relationships between lower extremity performance and health related quality of life in obese youth. Twenty obese and 20 age and sex matched healthy-weight youth were recruited. Peak torque of the major lower extremity muscles were measured. Functional performance was measured with single leg hop and single leg balance tests. The Paediatric Quality of Life questionnaire's physical and psychosocial health subscales were used. Paired t-tests and multiple regression analyses were performed. Obese youth demonstrated decreased peak torque in all muscles measured (P < 0.05), poorer functional performance (P < 0.05), and worse physical health related quality of life (P < 0.05) compared to healthy-weight youth. Lower extremity functional performance was associated with aspects of quality of life in the obese group (P = 0.002), but not in the healthy-weight group (P < 0.05). These results may assist in encouraging best practices in the promotion of exercise, physical activity, and quality of life in obese youth.  相似文献

Inconsistencies in the use and definition of psychological terms within the talent development literature have been identified. To advance the scientific field, the creation of a shared language is recommended. This review aimed to systematically (1) identify terms used in empirical studies to describe psychological components purported to facilitate athletes’ development; (2) analyse the definition and meanings of these terms; and (3) group, label, and define terms into meaning clusters. A systematic review using a narrative approach to synthesise information was conducted. A comprehensive literature search of SPORTDiscus, PsycINFO, PsycARTICLES, and ERIC was completed in May 2015. In total, 21 empirical studies, published between 2002 and 2015, met the inclusion criteria and were included in the narrative synthesis. Thematic analysis was used to analyse the findings. Identified psychological terms were categorised as psychological skills or psychological characteristics. Psychological skills were defined as athletes’ ability to use learned psychological strategies (e.g., self-talk) to regulate and facilitate the enhancement of psychological characteristics. Psychological characteristics were defined as predispositions that impact upon athlete development (e.g., self-confidence). Despite being relatively enduring and consistent across a range of situations, psychological characteristics can be regulated and enhanced through the use of psychological skills.  相似文献

The aim of the present study was to compare the peak anterior–posterior (Fy) and medio–lateral (Fx) ground reaction forces (GRFs) of women performing stationary running at different intensities in aquatic and dry land environments. Fourteen young women performed the stationary running exercise at three cadences (first ventilatory threshold, second ventilatory threshold and maximum effort, as determined during exercise in water) in aquatic and dry land environments. Two-way repeated measures ANOVA was used to analyse the data (α?=?.05). As a result, significantly lower peak Fy anterior, Fy posterior, Fx medial and Fx lateral values were observed for the aquatic environment, except for the Fy posterior at the first ventilatory threshold. Significant differences were observed between cadences in the peak Fy anterior, Fy posterior, Fx medial and Fx lateral values, with higher values for the cadence corresponding to maximum effort compared to the first ventilatory threshold, except for the Fy posterior and Fx medial in the aquatic environment. The results indicate that the horizontal GRFs are reduced in the aquatic environment and depend on the intensity of stationary running exercise performance.  相似文献

This study provides data from 73 educational team members who used an updated version of the Vermont Interdependent Services Team Approach (VISTA) to assist them in planning educationally necessary support services for 11 students with multiple disabilities in general education classes. These data provide evaluative consumer feedback about changes in VISTA based on limitations identified through previous research. The results indicated that the changes were perceived positively by consumers, particularly related to overall quality, practicality, and more substantive involvement of parents and general education teachers in support service decision-making. Study respondents also identified areas in need of continued improvement in VISTA. Implications for future research, development, and practice are discussed.  相似文献

This paper investigates how a sample of female Singaporean secondary school principals perceived their leadership styles and compares their responses to a similar study carried out recently of female English head teachers. The education systems of England and Singapore are quite different. The English environment allows schools significant autonomy in personnel management and the majority of head teachers and senior managers are male. In contrast, the Singaporean educational environment is quite centralized, including the management of career paths, and the proportion of female senior managers is much higher. Interviews were conducted with 11 female Singaporean principals to identify their styles of management, leadership perspectives, and attitudes. The discussion first focuses on whether or not the styles of the principals in relation to ‘masculine’ or feminine’ stereotypes of leadership were similar to those of the English head teachers. Further comparison is made of the leadership attributes of the two sets of principals, including styles of management, decision‐making, working environment, need for vision, and values.  相似文献

Building carefully on the college teaching and adult development literatures, this paper presents a model that describes the perspective of professors at various developmental positions with regard to their work as teachers. The model comprises five, interrelated positions: (a) three stable periods—Egocentrism (teacher-centeredness), Aliocentrism (learner-centeredness), and Systemocentrism (teacher/learner-centeredness); and (b) two transitional periods—one between each of the two potential movements from one stable period to the next. The model integrates the constructs of previous typologies, adds a significant new construct, and arranges the total array of perspectival constructs in a typical developmental sequence.  相似文献
