With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers’ cultural and economic assets, or capital, according to the work of Pierre Bourdieu’s sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers’ positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups’ habituses are described and analyzed; (1) The Manager of the Traditional, (2) The Challenger for Technology and (3) The Challenger for Citizenship. By constructing the habitus of the teachers in the different groups we can explain why teachers teach as they do and thereby make a contribution to both science education research and to teaching training, whereas reflective approach which also includes the individual dispositions and representations are paramount. In our paper we elaborate the grounds and implications of these findings further. 相似文献

This study's purpose is twofold: to introduce a new format into existing political entertainment research (“serious” political talk shows) and to establish a more specific definition of entertainment in a political context. To do so, the authors rely on a two-process-model of entertainment experiences. A telephone survey (N = 230) was conducted to analyze the antecedents and consequences of eudaimonic and hedonic entertainment experiences and to look into politically relevant variables and their distribution among viewers and nonviewers of such talk shows. The results highlight the importance of introducing new entertainment concepts and their relations to other relevant political and motivational variables into the research of political entertainment. More specifically, the findings demonstrate how entertainment experiences contribute to viewers' feeling of being informed and point out several differences between viewers and nonviewers concerning their internal political efficacy and political interest. Finally, looking at political talk shows from an audience perspective extends previous content-based taxonomies. 相似文献

The transition from further to higher education is marked by a series of challenges for the new student, not least the requirement to learn the discourse of academic practice, and referencing as a part of that. By perceiving what it means to reference, students should also come to understand what it means to write, including the problematic areas of authorship and ownership of ideas. Academic writing and paraphrasing are demanding concepts that require the student writer to enter into the academic discourse and relinquish their hold on the worlds of a text and embrace instead the argument behind them, in a form of ‘language-game’. Taking an interpretative, dialogic approach to referencing, the inherent playfulness of learning is emphasised through the use of Lego, used as a metaphor for the students' construction of meaning and to exemplify the discipline of citation and attribution. This paper outlines a method that metaphorically and literally enables students to construct and make visible the underlying theoretical philosophy of referencing and plagiarism by using Lego as a mode of authorship, in the context of the nature of academic discourse and what it means to write. In addition, the personal, engaging nature of the activity meant that it would be a more memorable activity too. 相似文献

Protein detection and quantification is a routinely performed procedure in research laboratories, predominantly executed either by spectroscopy-based measurements, such as NanoDrop, or by colorimetric assays. The detection limits of such assays, however, are limited to M concentrations. To establish an approach that achieves general protein detection at an enhanced sensitivity and without necessitating the requirement for signal amplification steps or a multicomponent detection system, here, we established a chemiluminescence-based protein detection assay. Our assay specifically targeted primary amines in proteins, which permitted characterization of any protein sample and, moreover, its latent nature eliminated the requirement for washing steps providing a simple route to implementation. Additionally, the use of a chemiluminescence-based readout ensured that the assay could be operated in an excitation source-free manner, which did not only permit an enhanced sensitivity due to a reduced background signal but also allowed for the use of a very simple optical setup comprising only an objective and a detection element. Using this assay, we demonstrated quantitative protein detection over a concentration range of five orders of magnitude and down to a high sensitivity of , corresponding to pM concentrations. The capability of the platform presented here to achieve a high detection sensitivity without the requirement for a multistep operation or a multicomponent optical system sets the basis for a simple yet universal and sensitive protein detection strategy. 相似文献

Objective
The aim of this study was to describe how sexually abused children experience the legal process, a process that includes being questioned by the police during the preliminary investigation and by lawyers and the prosecutor in the courtroom, and meeting other professionals from various agencies.Method
Face-to-face in-depth interviews were conducted with 10 children—9 girls and 1 boy between 9 and 15 years old—who had experienced child sexual abuse (CSA). The interviews were semi structured and carried out and analyzed by interpretative phenomenological analysis (IPA). The aim of IPA is to explore the participants’ views of the world and to adopt as far as possible an “insider perspective.” IPA draws on a tradition of phenomenology and symbolic interactionism in attempting to understand how people make sense of their experiences.Results
Five major themes emerged through the analysis: not being believed, making CSA visible, need for support, sanctions for offenders, and lack of respect for the child's integrity. Almost all the children had a feeling of not being believed. They described feelings ranging from anxiety to dread and even terror when they had to describe the CSA they had experienced. Even though the importance of support for such children is already well understood, the children stated that the support they were given was not sufficient. The children said that they wanted support from a single professional who was well informed about both the legal process and CSA. When the children were asked to reflect on sanctions against the abusers, they said that it was important that the perpetrator got treatment/therapy but they also said that imprisonment was desirable. Financial compensation was not as important to them; the damage had been done and money could not compensate for that damage. The children also said that both the lawyers and the media had treated them with disrespect.Conclusions
It is valuable for children who have been exposed to CSA to learn that they can take part in the legal process as equal partners with the other participants, and it is evident that the quality of psychological care and support needs to be improved. The children want to be participants in the legal process rather than passive objects of that process. 相似文献26.

Physical activity has not only been associated with increased physical and mental health, but also with beneficial effects on various cognitive and brain functions. This study investigated the effects of a motor and coordination oriented exercise intervention on academic achievements, attention/concentration ability, and on different facets of creative potential in a sample of school‐aged children between 11 and 14 years. The intervention was conducted during the morning school‐break over a time period of 4 weeks (5 units per week). The intervention was associated with beneficial effects on attention/concentration ability, basic arithmetic competence, and the fluency facet of creative potential. The finding that regular physical exercise during the morning break improves some basic academic and cognitive functions may motivate efforts to implement physical activity programs as promising and effective tools in the everyday school‐routine of the children to stimulate basic neurocognitive functions. 相似文献

In this paper, we investigate the assessment of educators and parents on the prosocial behavior of 5?year old kindergarteners. Using the data of the Kindergarten cohort (SC2) of the National Educational Panel Study (NEPS) we show that the assessments of two raters differ tremendously on the same subject. Further, the parents assess the prosocial behavior more positive than the educators do. While the parents’ assessment remains mostly stable across the investigated variables, the educators’ assessment highly varies. We find significant differences in the educators’ assessment regarding the age and the sex of the child as well as their language competencies. 相似文献

In 2008, articles by Bell and Schroeder provided an initial platform from which to develop a coherent definition of the term ‘virtual worlds’. Yet over the past ten years, there has been little development of the term. Instead there is confusion in the literature, with the introduction of new terms which are at times used to classify the type of virtual world and at others are used synonymously with the term. At the same time there has been a resurgence of interest in the potential of virtual reality which further muddies the conceptual waters. While the lack of a clear and common understanding of a term is not uncommon, there are implications for researchers and practitioners. To address these issues, this paper presents a new framework for the definition of virtual worlds, arguing what it is for a world to be virtual, the user experience that is a necessary part of this and the technical features which afford this. For the first time the relationships between commonly confused terms and technologies are identified to provide a much needed conceptual clarity for researchers and educators. 相似文献

There have been extensive studies of local residents’ perception and reaction to the impacts of mega events. However, there is limited empirical research on the social impacts that shape foreign attitudes toward the host country. The purpose of this study was to develop and validate the Olympic Games Attitude Scale (OGAS) to examine viewers’ perception of the Olympics hosting country. Participants (N = 483) were based on a convenience sample in a local community of the mid-Atlantic region in the United States. Results of the exploratory factor analysis identified four factors (economic advancement, image enhancement, community enrichment, and turmoil development) with a total variance of 67.59%. Confirmatory factor analysis showed that after removing one item, the 13-item OGAS provided a good fit to the data (comparative fit index [CFI] = .97; incremental fit index [IFI] = .97, standardized root mean square residual [SRMR] = .049; root mean square error of approximation [RMSEA] = .080). It is concluded that the OGAS is a valid measuring instrument for assessing viewers’ perception of hosting the Olympic Games. 相似文献
