This article is based on data generated in an ethnographic study of gender in a Swedish preschool. Drawing on Judith Butler’s understanding of performativity and (un)doing of gender, a new theoretical concept, situated decoding of gender, is further developed by showing how the material and spatial dimension of the educational practice and the teachers’ actions contribute to establishing and maintaining this process in an early childhood educational setting. Instead of normalising the gender binary, a reverse process occurs that turns what is perceived as feminine or masculine into a gender decoded state in which gender is made less relevant, or even irrelevant. It is argued that this continuous reiterative process emerges and is maintained by three main factors: (a) the preschool’s physical environment, (b) the regular and repetitive structure of the educational practice and (c) the consistent actions of the teachers in the everyday practice.  相似文献

The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by Vygotsky’s cultural-historical perspective on concept formation. The empirical data consist of pre- and post-interviews with children and documentation of their participation in the intermediate activity. This documentation is used in the post-interviews as a mutual ground for talking with the children about what they remember and how they understand the activity they participated in and what the activity intended to illustrate. The results are presented in terms of three inductively generated categories: ‘everyday’, ‘experientially-based’, and ‘generalized experiences’ concepts, respectively. The implications of these findings for early childhood chemistry (science) education are discussed.

While most German anatomy institutes provide only limited information about body donors and their lives, students have expressed a desire to learn more about these individuals, especially about their motivations to donate their bodies for the sake of medical education. In order to gratify this wish, as well as to further humanize body donors, an educational film was compiled, and a study designed to capture the film's effects on medical students. This is the first study using standardized, validated psychological tools to evaluate the impact of an educational film about body donors on students’ empathy and psychological stress levels. The study followed a longitudinal, controlled, and cluster randomized design, including 77 (48 females/29 males) participants who watched the video either before, midway, or after the dissection course. Questionnaires were completed at four points in time applying the Jefferson Scale for Empathy (JSPE-S) and the Interpersonal Reactivity Index (IRI) to measure empathy. Psychological stress levels were recorded by the Brief Symptom Inventory (BSI). Overall, students recommended the film to be shown to all students (median 6.0; maximum on the six-point Likert scale). Viewing the film revealed no significant changes between study groups or over time in JSPE-S sum scores. All groups demonstrated a significant reduction of BSI values before the dissection course actually started and increased values during the course, but both developments appeared not to be associated with the intervention. Overall, the educational film did not correlate with any negative effects on students’ empathy and psychological stress levels, and it was strongly approved of by students, as it provided more humanizing personal information about body donors without violating their anonymity.  相似文献

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes.  相似文献

Through the historic metaphor of hunting the essay examines the lifestyle of the dominant elites of Hungary between 1945 and 1990 on the basis of archival documents, private records, and oral history interviews. The analysis emphasizes the fact that there were interactions between the old, prewar aristocracy and the new state socialist elites. The co-incidence of lifestyles can be viewed through the lens of social and cultural change: new elements hit against the old, shaping and dissolving old behavioural patterns. The article analyses hunting in the contexts of social differentiation and social grouping. Using semiotics the author shows how, even during the era of state socialism, power and social distinctions were articulated on the level of lifestyles, and transmitted via the social, semiotic function of behaviours, patterns of taste, and forms of interaction. Thus, hunting evolved into a metaphor over time in Hungary: it was not only an indispensable part of the everyday life of the elite, but also became a symbol for belonging to it.  相似文献

This article investigates the implementation of the “förstelärare” or “First teacher” reform in Sweden. We draw upon the insights of a superintendent, union official, principal, three First teachers, and two of their colleagues in one school, and recent literature on career development reform. We employ Michael Fullan’s overview of the “right” and “wrong” drivers of educational reform to analyse the extent to which the First Teacher initiative cultivated productive “professional capital.” The research reveals: how broader national policy aims were in clear tension with municipal-wide school development, and school-level development efforts; the perverse effects of a strong focus upon salary on professional conduct; and how an emphasis upon teachers’ roles per se undermined the espoused policy focus on enhancing teaching. The research cautions against the problematic effects of the initiative on more profession-oriented prerogatives, and how more external, “deleterious,” drivers of reform militate against more productive professional capital.  相似文献

Assessing comfort of running footwear reliably is challenging. The purpose of this study was to compare the intra-rater reliability between different assessment types, to calculate intra-individual reliability scores and to evaluate the effect of rater selection based on individual reliability scores on group level reliability. Three assessment types: ranking, Visual Analogue Scale (VAS), and Likert Scale (LS) were provided twice in six separate sessions among 30 participants, who assessed comfort of five shoes after treadmill running. Spearman's rho provided an evaluation of inter-session relative reliability and typical error as a measure of absolute reliability for each assessment type. Ranking (r?=?0.70, 95% confidence interval [CI] 0.61–0.78) yielded the highest relative reliability for overall comfort, followed by VAS (r?=?0.67, 95% CI 0.56–0.75) and LS (r?=?0.63, 95% CI 0.52–0.72), with large-scale overlaps of CIs between assessment types. The same order of assessment types was found for the percentage of reliable raters (r?≥?0.7) with 60% in ranking scale, 47% in VAS and 37% in LS. Forming subgroups corresponding to the intra-individual reliability substantially increased group level reliabilities. Based on measures of relative reliability, an extreme reduction in resolution as provided by the ranking from pairwise comparisons seems to be a valuable tool in footwear comfort assessments if assessment time is of minor importance. No preference can be provided for the two investigated rating scales. Besides the assessment type, a selection of the best raters in additional reliability checks seems to be a prerequisite for further comfort-related studies.  相似文献

The lower limb kinetics of curve sprinting in amputees are not well described in the literature, particularly with respect to the effect of the side of amputation. This is an issue due to the importance of the knowledge for prosthetic design and classification of athletes. Thus, the aim of this study was to investigate the influence of side of amputation on curve sprinting performance in athletes with a unilateral leg amputation. A three-dimensional motion analysis system (Vicon), four force plates (Kistler) and a modified mathematical human model (ALASKA) were used to compare clockwise and counter clockwise curve sprinting lower limb kinematics and kinetics of a Paralympic medalist with a left-sided knee exarticular amputation. Results reveal that vertical ground reaction force application and total vertical impulse were lower when the affected limb was at the inside of the curve. The unaffected limb showed joint mechanics different to those established for non-amputee athletes and might contribute better to propulsion when being the inside limb. Curve sprinting biomechanics and the ability to attain high radial velocities are directly dependent on the side of amputation relative to the curve direction in a unilateral amputee athlete of highest performance level.  相似文献

Background: Due to migration processes, cultural diversity and strangeness are becoming characteristics of modern society. The competence to handle this heterogeneity – the so-called intercultural competence – is a key competence for all children and youths. Sports and physical education (PE) are often considered as a particular field for enhancing intercultural competence. However, until now there is no theory-based empirical study that proves this assumption. Purpose: This study was designed to examine the effects of a standardised, theoretically driven programme in PE on the development of underlying cognitive concepts of intercultural competence: acculturation attitudes and attitudes towards cultural diversity. Research design: The research design consists of a quasi-experimental design with four measurement points. The intervention group (N?=?69; mean age?=?11.6 years (SD?=?0.60)) followed standardised and theory-driven intervention lessons following the didactical guidelines of the concept of ‘Intercultural Movement Education’ (IME). The developed games tend to trigger ‘crises’ with the aim to insecure students. These experienced insecurities were afterwards reflected upon with the students. The internal control group (N?=?63; mean age?=?11.8 years (SD?=?0.62)) and external control group (N?=?93; mean age?=?10.8 years (SD?=?0.69)) were taught in a unspecific manner. The impact of the intervention study programme was tested with a reliable and valid questionnaire. Results: A significant time by group interaction effect for the subscale ‘assimilation/segregation’ of acculturation attitudes was found in boys and in girls. The attitudes increased significantly after the intervention. For the girls, the intervention group showed also a significant decrease of the attitude ‘integration’. No significant impact of the intervention study on the attitudes towards cultural diversity could be identified either with boys or girls. Discussion: The effects of the study are ambivalent. The significantly increased assimilative attitudes can be interpreted as a need for a sense of security. This is also underlined by the decrease of the integration attitude that values the maintenance of cultural integrity. It must be critically discussed whether the ‘crises’ were too intense and not adapted to the children’s skills to overcome them. Second, we have to critically analyse whether the discussions with the students about their experiences were sufficiently focused to debrief the students. Summary for practitioners: The competence to handle heterogeneity – the so-called intercultural competence – is a key competence for children and youths. Sports and PE are often considered as a particular field for enhancing intercultural competence. However, until now there has been no theory-based empirical study that proves this assumption. This paper describes the development, implementation and evaluation of an intervention programme on intercultural learning in PE along the didactic guidelines of IME. This programme tries to trigger ‘crises’ that stimulate the students to react and think about their self- and world relations. The statistical analyses show that the ‘crises’ were probably too intense as the students’ scores in assimilation attitudes increased. This lead to the didactical reflection of the implementation of intercultural learning processes in PE.  相似文献
