This paper analyses how three European countries produce and use data within a specific educational policy field, that of school leaving and graduation. It compares how stakeholders in England, Finland and the Netherlands know what happens to the leavers from schools and universities. Through gathering evidence about the methodological underpinnings of the school leavers’ and graduates’ information systems (SLGIS) and whose data needs they aim to satisfy, this research provides insight into the discrepancies of data production. Moreover, as stakeholders from the policy and the institutional level are represented to a different extent when SLGIS are set up, the utility of the resulting data in their work is of differing degrees. The paper models the problems of how SLGIS are set up and utilised, thus suggesting some of the possible solutions. Using this particular example, the paper highlights the discrepancies of data production and utilisation in terms of the focus, the timing, the methodology and sampling as well as the processes of dissemination. To provide a wider relevance, the paper outlines key issues around the utility of research evidence.  相似文献

In this work, we present a marine ecology inquiry-based activity, implemented with 164 primary school students. The main goal was to evaluate the activity's impact on students’ understanding about biodiversity and scientific procedures. We also aimed to analyse the potential use of personal meaning maps (PMMs) to assess the impact of the activity on students’ ideas about the topics explored. The results revealed that fieldwork and the exploration of real data were the aspects most emphasised by all intervenient. Finally, the PMMs proved to be a good tool to evaluate the impact of activities developed outside classroom, with primary school levels.  相似文献

Expansions of trinucleotide repeats at the level of genomic DNA are increasingly recognized as a cause of a number of neuropsychiatric disorders. Triplet repeat disorders are commonly classified into two groups, those with moderate CAG expansions that result in a polyglutamine stretch in the gene products and those with very long expansions, usually non-CAG, that are not translated. The triplet repeat intergeneration and intra-generational instability, and genetic anticipation characterize disorders. Most of the diseases caused by expanded CAG repeat share common features, which include neurodegeneration, a dominant pattern of inheritance and widespread expression of the gene products with neuronal loss restricted to distinct subset of neurons. Neurodegenerative changes associated of CAG expansion disorders is explained in terms of intra and extra cellular aggregation of mutant gene products, the insoluble nature of the protein(s) being attributed to the presence of polyglutamine stretches, hence their neurotoxic effects. methods based on poymerase chain reaction have become handy in the diagnosis of these genetic disorders. Progress in transgenic animal models for these disorders will be critical for understanding the progress of these disorders and for testing new therapeutic strategies.  相似文献

In this study, we assessed the pre-game hydration status and fluid balance of elite young soccer players competing in a match played in the heat (temperature 31.0 ± 2.0 ° C, relative humidity 48.0 ± 5.0%) for an official Brazilian soccer competition. Fluid intake was measured during the match, as were urine specific gravity and body mass before and after the game to estimate hydration status. Data were obtained from 15 male players (age 17.0 ± 0.6 years, height 1.78 ± 0.06 m, mass 65.3 ± 3.8 kg); however, data are only analysed for 10 players who completed the full game. The mean (± s) sweat loss of players amounted to 2.24 ± 0.63 L, and mean fluid intake was 1.12 ± 0.39 L. Pre-game urine specific gravity was 1.021 ± 0.004, ranging from 1.010 to 1.025. There was no significant correlation between sweat loss and fluid intake (r = 0.504, P = 0.137) or between urine specific gravity and fluid intake (r = -0.276, P = 0.440). We conclude that young, native tropical soccer players started the match hypohydrated and replaced about 50% of the sweat lost. Thus, effective strategies to improve fluid replacement are needed for players competing in the heat.  相似文献

Abstract

The WaterCircle (WC) project was implemented in a school, with young adolescents, to address environmental problems. Framed in a participatory research (PR) approach, this school-and-community based intervention includes the use of online tools through which environmental problems in the community are discussed within and by a group of students. Using a quasi-experimental design, with intervention and control groups, the present study involved 361 young adolescents, in grades 7 to 9, from a public school in the northern region of Portugal. Mixed methods were used for data collection and analysis, namely based on questionnaires administered in the pre- and post-test moments, as well as on students’ discourses produced in the classroom during planned activities. Statistically significant changes on self-efficacy were found for the experimental group, suggesting that the intervention program has the potential to raise young people’s empowerment regarding environmental issues. The WC program seems to foster students’ awareness of the socio-political dimensions of environmental problems, since they were able to identify different actors in the community who should be involved in the proposed solutions. Longer-term intervention is required to foster the impact of the PR on the students’ experience.  相似文献

The curiosity of 120 elementary school children, aged five through thirteen years, was assessed by three measures: (1) the amount of coordinated sensory-motor activity directed toward designated objects in a waiting room environment during a 10-minute waiting period, (2) the number of unsolicited questions asked within the same time period and environment, and (3) teacher ratings, where classroom teachers estimated children's curiosity based on their normal classroom behavior. In a three-way analysis of variance, the amount of curiosity expressed through motor activity was found significantly related to groups based on racial-ethnic origins, but not to groups based on age or sex. The amount of curiosity expressed through motor activity was negatively correlated with teacher ratings in one class but not significantly correlated in three other classes. Children who asked most questions were rated highest in curiosity by their teachers, but exhibited least curiosity through motor activity in the waiting room.  相似文献

The Role of Class Teachers in a Key Secondary School in Shanghai   总被引:2,自引:0,他引:2  
This paper reports on an investigation carried out in a 'key' secondary school in Shanghai. This investigation is set in the broader context of current developments in Chinese Education. Perhaps the first surprising discovery is that the affective aspects of education are seen as highly significant in these developments. Given the vast numbers involved and great regional differences, what is described here is likely to be only representative of the best practice. The particular focus of this paper is on the multifaceted role of the class teacher. The second surprise is that though there are great differences, not least in the politicization of education, there are striking parallels with English education and there are some instances where the class teacher's practice as described here is in advance of many of their English counterparts.  相似文献

In this work, we explore journal writing as a way to come to know culture, particularly cultural phenomenon, vastly different from one’s own firmly held and enacted beliefs. In this research, we accept the premise that writing is a way of knowing and adopt journal writing as a tool through which students can explore the knowledge they have developed as a result of their academic travel study experiences, all being participants in the China Study Abroad Program. Narrative threads from numerous graduate students’ journals are seamed together through the use of narrative inquiry’s analytical tools. The narrative exemplars that were created reinforce the personal, social, and professional importance of creating a reflective writing space through which many expressions of culture and students’ reflective responses to them can be channeled in productive and potentially transformative ways.  相似文献

In adolescence, both identity concerns and feelings of loneliness are of utmost importance to the experiences of young people. Yet, a theoretically grounded hypothesis that identity and loneliness are developmentally related has never been tested. Thus, the aim of this study was to disentangle the longitudinal associations between identity processes in educational and interpersonal domains and loneliness in adolescence. The sample consisted of 632 Lithuanian adolescents (53.2% girls; Mage = 14.32; SDage = 1.09) participating in a four-wave study with 6-month intervals between assessments. Cross-lagged analyses revealed reciprocal associations between identity processes and loneliness in the educational domain and unidirectional effects of adolescents' reconsideration of commitment on loneliness in the interpersonal domain.  相似文献
