ABSTRACT Reliability of accelerometer-determined physical activity (PA), and thus the required length of a monitoring period, appears to depend on the analytic approach used for its calculation. We compared reliability of objectively measured PA using different resolution of data in a sample of 221 Norwegian 2–6-year-old children providing 2–3 valid 14-day periods of accelerometer monitoring (ActiGraph GT3X+) during September–October, January–February, and May–June 2015–2016. Reliability (intra-class correlation [ICC]) was measured for 1–14 days of monitoring across the measurement periods using linear mixed effect modelling. These results were compared to reliability estimated using different resolution of data using the Spearman–Brown formula. The measured reliability improved only marginally with increased monitoring length and levelled off after 5–6 days. Estimated reliability differed substantially when derived from different resolution of data: 3.9–5.4, 6.7–9.2, 13.4–26.7 and 26.3–87.7 days of monitoring was required to achieve an ICC = 0.80 using an hour-by-hour, a day-by-day, a week-by-week and a period-by-period approach, respectively. Reliability could not be correctly estimated from any single resolution of data. We conclude that reconsideration is needed with regard to how reproducibility of objectively measured PA is analysed and interpreted. 相似文献

A feature of academic literature on physical education teacher education (PETE) is the expectation that it can and should impact upon student teachers' beliefs and prospective practices in some significant ways. This is despite research over the last 20 years or more alluding to the apparent failure of PETE to ‘shake or stir’ (Evans et al., 1996) what might be termed the (typically conservative and conventional) pre-dispositions of student and early career PE teachers. In this article, we examine the perceptions of PE student teachers in Norway in order to ascertain just what it is that makes them so resistant to change and, for that matter, such infertile ground for sowing the seeds of reflexivity. The study involved semi-structured interviews with 41 PE student teachers from the three routes through teacher education available at Nord University College (Nord UC). Among the main themes identified in the data were the PE students' perceptions of: the purposes (and ostensible benefits) of school PE and PETE as well as the nature of PETE itself (including subsidiary themes of sporting and teaching skills, other ‘competencies’, school placements, mentoring and mentors, PETEs' (physical education teacher educators) teaching styles and the students teachers' relationships with the PETEs). The article concludes that, as far as the students at Nord UC were concerned, the significance of PETE revolved around the programme's efficacy in developing the sporting skills and teaching techniques they viewed as central to their preparation for teaching. The minimal impact of the more theoretical aspects of PETE appeared to be partly attributable to the students' perceptions of PE as synonymous with sport in schools and partly to their particularly pragmatic orientations towards PETE. In this vein, the students viewed experience as the most important, most legitimate ‘evidence’ on which to base their beliefs and practices and were resistant to the ‘theory’ of teacher education, rationalising their tendencies to select the evidence that suited them. 相似文献

The aim of this research is to develop and validate a self-report measure of mindfulness and coping, the mindful coping scale (MCS). Dimensions of mindful coping were theoretically deduced from mindfulness theory and coping theory. The MCS was empirically evaluated by use of factor analyses, reliability testing and nomological network validation. The study's participants were high school students from two high schools, covering all streams. Further validation was obtained by correlating the MCS-subscales with an appraisal theory-based measure of coping strategies. Results from factor analyses supported the proposed measurement model and Cronbach's alphas indicated good internal consistency for the four sub-scales. Furthermore, correlations with instrument for measuring coping were mainly in accordance with our expectations. The above supports the validation of our instrument. 相似文献

Background and purpose: Many researchers agree that teachers’ learning processes are social and that teachers need to be brought together to learn from each other. Researchers have also stated that intellectual and pedagogical change requires professional development activities that take place over a period of time in school. The purpose of the study presented in the article was to develop knowledge about the teachers’ learning when taking part in a school-based development project. Main argument: The study shows that it takes some time before the teachers identify with the work in school-based development. Even though the national authorities decided what to focus on during the development work, the participating teachers felt that they had autonomy in the work. The study presented in the article shows that it is important for the teachers’ learning culture that they are listened to and taken into consideration and that the leaders have competence in leading school-based development to support the teachers’ learning. Sources of evidence and method: The article is based on a study connected with school-based development in three lower secondary schools. Qualitative interviews were used as the data-collection strategy to capture the teachers’ and school leaders’ experiences and reflections. Conclusion: The article presents new knowledge connected with teachers’ learning in school-based development. The study presented in the article shows that schools’ learning culture can make a difference for the teachers’ learning and their job satisfaction and wellbeing. 相似文献

Terror attacks force democratic societies to mobilize, reinforce and rethink core values, including media freedom and freedom of speech. The present article analyzes how one traumatic event—the 2011 Oslo terror—challenged editorial practices related to editorial control and open debate in major Norwegian media organizations. Meeting the call for more research on disruptive media events in a hybrid media landscape, it illuminates how professional media balance critical debate with strategies for societal recovery in contemporary post-crisis contexts. Based on in-depth interviews with debate editors, the article documents how terror profoundly challenges editorial practices, routines and norms in media organizations with debates in multiple formats and platforms. In their online comment sections, the media organizations all moved towards a more interventionist policy introducing multiple new control measures. In the traditional op-ed formats, however, they selectively expanded the range of voices and included actors deemed too extreme prior to the attacks. Theoretically the article contributes to the literature on disruptive (key) events, editorial strategies during crisis, editorial control in contemporary media systems and editorial approaches to mediated deviance. 相似文献

Drop-out from upper secondary school is considered a widespread problem, closely connected with youth unemployment. The aim of the current study was to examine whether parents' level of education predicted drop-out for 16–24-year-olds when accounting for basic skills. For this purpose, data from the Norwegian (n?=?996) and American (n?=?641) samples in the Adult Literacy and Life Skills Survey (ALL) were used. Stepwise logistic regression showed that parents' educational level was a significant predictor of early school leaving in both countries, but explained significantly more of the variance in USA than in Norway. Mothers' educational level predicted early school leaving in USA also when accounting for youth's basic skills, but this was not the case in Norway. 相似文献

The aim of this study is to investigate adolescents’ perspectives on mental healthcare services. Based on theoretical perspectives concerning barriers for help-seeking, individual interviews were carried out in order to obtain the adolescents’ perspectives on knowledge of services for mental health problems, potential barriers for help-seeking, and services to which they have access. The sample consisted of vocational students from an upper secondary school in the southwest of Norway (n = 8). None of the informants was currently in treatment for mental health problems. Interview data were transcribed and analysed with the assistance of NVivo Software. Qualitative content analysis indicated that the adolescents have limited knowledge of available resources, and, that stigma-related factors may prevent the adolescents from seeking help for mental health problems. Future directions for delivering mental health services for adolescents are given. 相似文献

Rhythm plays an organisational role in the prosody and phonology of language, and children with literacy difficulties have been found to demonstrate poor rhythmic perception. This study explored whether students’ performance on a simple rhythm task at school entry could serve as a predictor of whether they would face difficulties in word reading and spelling at the end of grade 1. The participants were 479 Norwegian 6-year-old first graders randomized as controls in the longitudinal RCT on track (n = 1171). Rhythmic timing and pre-reading skills were tested individually at school entry on a digital tablet. On the rhythm task, the students were told to tap a drum appearing on the screen to two different rhythms (2 Hz paced and 1.5 Hz paced). Children’s responses were recorded as they tapped on the screen with their index finger. Significant group differences were found in rhythm tapping ability measured at school entry, when groups were defined upon whether children went on to score above or below the 20th percentile reading and spelling thresholds in national assessment tests at the end of grade one. Inclusion of the school-entry rhythmic tapping measure into a model of classification accuracy for above or below threshold reading and spelling improved accuracy of classification by 6.2 and 9.2% respectively. 相似文献
