The aim of the present research was to examine adolescents’ definitions of bullying in a nationally representative sample of adolescents in Ireland. Definitions of bullying were examined according to age, gender, and bullying experiences. A sample of 4358 adolescents aged 12–19 years (M?=?14.99 years, SD?=?1.63) provided their definitions of bullying as part of the My World Survey-Second Level. The definitions were explored using content analysis. Adolescents differed in terms of their definition of bullying, with younger students frequently describing the nature of bullying as mean, while older students displayed a heightened awareness of the feelings associated with being a victim of bullying. Older females and those who had experienced bullying were more likely to discuss the emotions associated with bullying compared to males and those who had not been bullied. Adolescent definitions of bullying were not in line with widely accepted researcher definitions. Recommendations are made for researchers and those designing anti-bullying interventions and educational programmes. 相似文献

Abstract The paper addresses the questions of identity, ethics and organization for academic developers ('AD’ is used as an umbrella for academic staff development plus a number of other academic‐related professional university roles). It inquires into the degree of role differentiation between this occupational cluster and others that resemble it, outside as well as inside the universities. It argues, following Clark and Boyer, that ‘AD’ is both a scholarly and an academic pursuit, and adds that it is characterized uniquely by its focus on change and development, and that the nature of its ‘discipline’ is somewhat problematic. The paper examines the occupational freedoms of AD people and their special knowledge‐base, and argues for a ‘temptations‐based’ rather than a ‘virtues‐based’ approach to creating an ethical schema. It concludes with observations about how to achieve a firm professional identity for AD and recommends new organizational machinery to both politicize and defend the distinctive AD role in academia. 相似文献

Undergraduate university students (n = 132) completed a questionnaire containing measures of psychological variables, verbal ability, an evaluation of their course of study, and demographic characteristics. We also had access to their academic results. We examined the relationships among these variables, especially the psychological variables, and compared them with those posited by recent theoretical work that makes connections among motivation, self‐regulation, and self‐efficacy. We then looked at which variables predicted academic achievement. The sample contained two sub‐samples: mature‐age students who had entered university via an enabling program; and younger students who entered university on the basis of high school results. With universities under severe financial pressure, university‐run enabling programs must demonstrate their effectiveness in terms of students’ successful progress in undergraduate degrees if they are to continue. We compared these two groups of students on the measures noted above. 相似文献

The structural change of the oviduct of freshwater shrimp （Macrobrachium nipponense） during spawning was examined by electron microscopy. The oviduct wall structural characteristics seem to be influenced significantly by the spawning process. Before the parturition and ovulation, two types of epithelial cells （types Ⅰ and Ⅱ） are found in the epithelium. The free surfaces of type Ⅰ and type Ⅱ cells have very dense long microvilli. Under the type Ⅰ and type Ⅱ cells, are a relatively thick layer of secreting material and a layer of mostly dead cells. After ovulation, two other types of epithelial cells （types Ⅲ and Ⅳ） are found in the oviduct wall epithelium. The free surface of type Ⅲ cells only has short microvilli scattered on the surface. The thick layer with secreting material and the dead cell layer disappeared at this stage. In some type Ⅲ cells, the leaking out of cytoplasm from broken cell membrane led to the death of these type Ⅲ cells. The transformation of all four types of epithelial cells was in the order： Ⅳ→Ⅰ→Ⅱ→Ⅲ. 相似文献

The present study investigated how pre-service teachers’ motivation and their sense of teaching efficacy influence their expectation about reality shock during the first year of professional teaching. A total of 533 pre-service teachers at a state university in the US Midwest participated in this study. The results showed that the pre-service teachers’ expectation of reality shock was negatively related to teacher efficacy and intrinsic motivation while it was positively related to introjected and external motivation. The results of a hierarchical regression analysis revealed that pre-service teachers’ sense of efficacy and introjected motivation were strong predictors of their expectation of reality shock, when gender difference was controlled for. There was an interaction effect between intrinsic motivation and teachers’ sense of efficacy in predicting the reality shock expectation. We discussed the educational implications for future research in an endeavour to reduce the reality shock among novice teachers. 相似文献

The aim of this self-report study is to analyze proposed interrelations between value orientations, self-control, frequency of school–leisure conflicts, and life-balance in adolescence. Life-balance is defined as satisfying time investment in different life areas. The tested model posits that self-control is negatively related to conflict frequency and that the latter is negatively related to life-balance. Achievement and well-being value orientations, in turn, should be connected to the degree of self-control and the frequency of goal conflicts. In the study, 817 German 8th-graders with a mean age of 13.4 years participated. Results from structural equation modeling supported the proposed model. The results suggest that fostering self-control can be a promising approach to decrease the frequency of goal conflicts, and thus increase students' experience of life-balance. 相似文献

May you enjoy good fortune as expansive as the Eastern Sea, and longevity as long as the Southern Mountain 福如东海寿比南山INTRODUCTION Good fortune and auspicious thought are central to all aspects of Chinese life and culture. The Chinese believe that by layering their lives with lucky objects and images, they increase their chances of a happy and prosperous existence. Over the centuries, a symbolic language has evolved that expresses these ideas in art, craft, architecture, language, and everyday objects. Lucky words and phrases were used to create an environment protected from misfortune, bad omens, and disaster. In the Han dynasty (206 B.C.*-A.D. 相似文献

The field of information technology in education is nearly 30 years old. There have been many impressive achievements during that time. However, the field seems to have developed a number of theories, concepts, and activities that are often taken for granted and are regarded as sacrosanct. A case is made for the notion that theories should be practical and that it is possible to have too much of a good thing. 相似文献

One of the most frequently recurring themes in captioning is whether captions should be edited or verbatim. The authors report on the results of an eye-tracking study of captioning for deaf and hard of hearing viewers reading different types of captions. By examining eye movement patterns when these viewers were watching clips with verbatim, standard, and edited captions, the authors tested whether the three different caption styles were read differently by the study participants (N = 40): 9 deaf, 21 hard of hearing, and 10 hearing individuals. Interesting interaction effects for the proportion of dwell time and fixation count were observed. In terms of group differences, deaf participants differed from the other two groups only in the case of verbatim captions. The results are discussed with reference to classical reading studies, audiovisual translation, and a new concept of viewing speed. 相似文献

This study examined the mediating roles of prospective teachers’ boredom coping strategies (i.e. cognitive-approach, behavioral-approach, cognitive-avoidance, and behavioral-avoidance strategies) in the relationships between their perceptions of instrumentality and four aspects of engagement (i.e. agentic engagement, behavioral, engagement, emotional engagement, and cognitive engagement). A total of 521 prospective teachers participated voluntarily in the study. In addition to the latent factor and observed factor correlation analyses, a series of structural equation modeling analyses were conducted in order to examine the mediating roles of boredom coping strategies. The results demonstrated that perceived instrumentality, boredom coping strategies with the exception of cognitive-avoidance orientation, and four aspects of engagement were significantly related to each other. The results also showed that the relationships between perceived instrumentality and agentic engagement, behavioral engagement, emotional engagement, and cognitive engagement were slightly, but significantly mediated by cognitive-approach orientation. Implications for teacher education and directions for future studies were also discussed in the present study. 相似文献

This essay describes an educational initiative that used environmentally themed (green) hip-hop to stimulate learning in an environmental science classroom. Students were then challenged to compose their own green hip-hop and their lyrics demonstrated skills that have thematic consistency around what is called a Critical Ecological Literacy (CEL). An analysis of more than 200 creative pieces collected from eight runs of this curriculum over four years shows that CEL can be used as a guiding concept for the creation of curriculum targeting urban areas and racially diverse learners. Several examples of this student-produced green hip-hop are shared to delineate elements of CEL that can help educators evaluate student learning as well as their own teaching materials. 相似文献

Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform efforts. Nonetheless, there is a dearth of research on conceptualizing explanation in science education. Using a philosophically guided framework—the Nature of Scientific Explanation (NOSE) framework—the study aims to elucidate and compare college freshmen science students', secondary science teachers', and practicing scientists' scientific explanations and their views of scientific explanations. In particular, this study aims to: (1) analyze students', teachers', and scientists' scientific explanations; (2) explore the nuances about how freshman students, science teachers, and practicing scientists construct explanations; and (3) elucidate the criteria that participants use in analyzing scientific explanations. In two separate interviews, participants first constructed explanations of everyday scientific phenomena and then provided feedback on the explanations constructed by other participants. Major findings showed that, when analyzed using NOSE framework, participant scientists did significantly “better” than teachers and students. Our analysis revealed that scientists, teachers, and students share a lot of similarities in how they construct their explanations in science. However, they differ in some key dimensions. The present study highlighted the need articulated by many researchers in science education to understand additional aspects specific to scientific explanation. The present findings provide an initial analytical framework for examining students' and science teachers' scientific explanations. 相似文献
