This study investigated the attitudes of 43 teachers and school administrators towards sex education, young people's sexuality and their communities in 19 secondary schools in rural KwaZulu-Natal, South Africa, and how these attitudes affect school-based HIV prevention and sex education. In interviews, teachers expressed judgemental attitudes towards young people's sexuality and pregnant students, and focused on girls' perceived irresponsible behaviour instead of strategies to minimise HIV risk. Despite general awareness of the HIV epidemic, few teachers perceived it as an immediate threat, and teachers' own HIV risk was infrequently acknowledged. Teachers perceived themselves to have higher personal standards and moral authority than members of the communities and schools they served. Male administrators' authority to determine school policies and teachers' attitudes towards sexuality fundamentally affect the content and delivery of school-based sexuality education and HIV prevention activities. Opportunities to create a supportive educational environment for students and for female teachers are frequently missed. Improving teachers' efficacy to deliver impartial, non-judgemental and accurate information about sex and HIV is essential, as are efforts to acknowledge and address their own HIV risks. 相似文献

In 2004, the Social Sciences and Humanities Library at the University of California–San Diego implemented restaurant-style pagers to notify waiting patrons that the reserve collection materials they needed were available. The authors describe the university libraries’ process for implementing the pagers and the success staff has had with pagers over the past four years, list other libraries that use pagers, suggest other library uses for pagers, and offer guidance to institutions that might consider this service enhancement. 相似文献

Insights and Conflicts in Discussing Recursion: A Case Study 总被引:1,自引:1,他引:0
Dalit Levy 《Computer Science Education》2013,23(4):305-322
Recursion is a significant concept, appearing in almost every introductory course in Computer Science (CS). CS educators and educational researchers often refer to difficulties in learning and teaching recursion. However, the research literature barely addresses the unique ways in which students relate to this interdisciplinary concept and the particular learners’ language concerning recursive phenomena. The gap is most apparent when seen through a constructivist lens, where the students’ prior knowledge and idiosyncratic conceptions should be referred to and reflected upon in order to serve as a basis for further knowledge construction. This paper reports on a study in which a collaborative classification of several recursive phenomena are used to facilitate the construction of recursion. The student discourse was recorded and analyzed, and a grounded categorical system was formed and examined. Preliminary results indicate some basic aspects of recursion in the student discourse, although the students apparently talk a very different language from that of the experts. Some ‘potentially rich’ discourse episodes were evident as well, representing conflicts among alternative conceptions. Such episodes can serve as a springboard for further learning. 相似文献

This study examined the relationship between students’ perceptions of teacher–student interaction and academic performance at an asynchronous, self-paced, statewide virtual high school. Academic performance was measured by grade awarded and course completion. There were 2269 students who responded to an 18-item survey designed to measure student perceptions on the quality and frequency of teacher–student interaction. Quality of interaction was subdivided into three constructs representing feedback, procedural, and social interaction. A confirmatory factor analysis helped to establish the fit of the statistical model for teacher–student interaction. Hierarchical logistical regression indicates that an increase in the quality and frequency of interaction resulted in an increased likelihood of course completion but had minimal influence on grade awarded. The estimated effect for quality and frequency composite items on completion was .83 and .56 respectively. Low practical significance of student–teacher interaction on grade awarded may be the result of mastery-based teaching approaches that skew grades for the completers toward the high end. 相似文献

Roy Levy 《Structural equation modeling》2013,20(4):663-685
Bayesian approaches to modeling are receiving an increasing amount of attention in the areas of model construction and estimation in factor analysis, structural equation modeling (SEM), and related latent variable models. However, model diagnostics and model criticism remain relatively understudied aspects of Bayesian SEM. This article describes and illustrates key features of Bayesian approaches to model diagnostics and assessing data–model fit of structural equation models, discussing their merits relative to traditional procedures. 相似文献

The ability to care for oneself, near and distant others, animals, plants, human-made objects, and even ideas is an antidote for violence in its many forms as experienced in childhood as well as adulthood. This article makes a case for facilitating the development of the ability to care as children develop. The authors emphasize the importance of teachers facilitating this development. However, early education teachers may not be able to nurture the ability to care in others without the ability to care being facilitated in their own development. This article emphasizes the importance of creating caring teacher education programs as a model to foster its development in preservice early education teachers. 相似文献

Abstract The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18 – 38 years (mean = 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes. 相似文献

The Transtheoretical Model (Prochaska & Marcus, 1994) has been widely used as a framework for understanding exercise behavior change. The purpose of this study was to clarify equivocal research findings reported for model predictions when examining stage movement over time rather than static stages and to provide some evidence of the construct validity of transitional stages. Participants were female (n = 285) and male (n = 243) undergraduates (M age = 19.9 years, SD = 2.7) who completed previously validated questionnaires twice, separated by 9 weeks, that assessed stage of change, exercise behavior, processes of change, pros and cons of exercise, and exercise self-efficacy. Participants were classified into one of five transitional shift groups based on their responses at baseline and follow up: (a) stable sedentary, (b) stable active, (c) activity adopters, (d) activity relapsers, and (e) perpetual preparers. Results of a 5 (group) x 2 (time) repeated measures (RM) analysis of variance (ANOVA) examining exercise behavior revealed a significant interaction (p < .001) and supported transitional stage classification, with activity adopters and stable actives increasing exercise over time and relapsers decreasing activity. Separate 5 (group) x 2 (time) RM ANOVAs examining model constructs revealed no significant interaction for cognitive processes of change; however, activity adopters and stable actives reported significant (p < .01) increases in the use of behavioral processes over time, while only the activity relapsers and perpetual preparers reported decreases. Activity relapsers also reported significant (p < .05) decreases in the pros of exercise. No significant interactions were found for the cons of exercise behavior. Unlike findings reported in cross-sectional studies, increases in self-efficacy did not accompany increases in exercise stage. The findings strongly support examination of stage movement classifications rather than static stages, as these transitions provide greater insight into the mechanisms of exercise behavior change. 相似文献

A particular model of scientific achievement is embedded within the Nobel Prize, one that privileges the scientific `loner', whoachieves a distinct discovery at a particularmoment in time. A common criticism of this`individualistic' story of achievement is thatit obscures the social and cultural factors inscientific discovery. A collective story,highlighting the role of social relations andscientific milieux, may offer more explanatorypower in accounting for scientific discoveriesand inventions. This paper explores the processby which Henry Dale became recognized as thediscoverer of the chemical transmission ofnerve impulses. It compares the explanatorypower of the story of individual creativitywith a story that highlights the interactionbetween a scientist and his environment. 相似文献
