Despite the crucial role of teachers in fostering children's academic learning and social–emotional well‐being, addressing teacher stress in the classroom remains a significant challenge in education. This study reports results from a randomized controlled pilot trial of a modified Mindfulness‐Based Stress Reduction course (mMBSR) adapted specifically for teachers. Results suggest that the course may be a promising intervention, with participants showing significant reductions in psychological symptoms and burnout, improvements in observer‐rated classroom organization and performance on a computer task of affective attentional bias, and increases in self‐compassion. In contrast, control group participants showed declines in cortisol functioning over time and marginally significant increases in burnout. Furthermore, changes in mindfulness were correlated in the expected direction with changes across several outcomes (psychological symptoms, burnout, and sustained attention) in the intervention group. Implications of these findings for the training and support of teachers are discussed.  相似文献

We report on a project currently in progress that aims to identify through research the range of factors (individual, school and out-of-school, including home) and their interactions that influence post-16 (i.e. post-compulsory) participation in mathematics and physics in the UK and to assess their relative importance among different student populations. In this project, we are beginning to elucidate the views of students and examine the sources of these views by exploring the contexts in which both school and university students experience barriers or opportunities and form their identities with regard to participation in mathematics and physics. Our focus in this paper is on our methodology, the reasons for it and how and why our approach to data collection developed during the project. We situate our work within a mixed-methods approach, using multilevel modelling and discourse analysis to analyse and interpret our findings that derive from our own questionnaires, interviews and ethnography and from existing large-scale datasets. We argue that greater acknowledgement in the education literatures that investigate student participation in mathematics and science needs to be made than is usual of the range of factors, including unconscious forces that may affect participation.  相似文献

Creating public value is a key goal of public administrations, both in their daily business and in the growing field of smart government and smart cities, which focuses on IT-enabled innovations in the public sphere. However, many public administrations still struggle with such innovations due to complex technologies, high investments, and the numerous stakeholders involved. To address this issue, some local governments in continental Europe have turned to collaborative innovation approaches, partnering with (semi-)public utility companies in the hope that their additional innovation assets will boost innovativeness. Nevertheless, it remains unclear how exactly such collaborations should be governed to ensure that the focus remains on creating public value, as utility companies may have their own agendas. To explore this question, we conducted a comparative case study in the context of smart city initiatives with four cases in Swiss local governments. Drawing on agency and stewardship theory, we then propose a model of public-value-focused collaborative innovation, enabling us to explore various collaboration characteristics and their effects on public value creation. Our findings suggest that both agency- and stewardship-based collaborations increase innovativeness. However, while agency collaborations tend to produce smart city innovations that mainly serve the utility companies' business interests, stewardship relationships lead to innovations that are focused more on public value creation. As such, our study extends the literature on the effects of collaborative innovation on public value, and it provides practical recommendations on how such collaborative innovation should be designed.  相似文献

The use of mixed reality in science education has been increasing and as such it has become more important to understand how information is learned in these virtual environments. Spatial ability is important in many learning contexts, but especially in neuroanatomy education where learning the locations and spatial relationships between brain regions is paramount. It is currently unclear what role spatial ability plays in mixed reality learning environments, and whether it is different compared to traditional physical environments. To test this, a learning experiment was conducted where students learned neuroanatomy using both mixed reality and a physical plastic model of a brain (N = 27). Spatial ability was assessed and analyzed to determine its effect on performance across the two learning modalities. The results showed that spatial ability facilitated learning in mixed reality (β = 0.21, P = 0.003), but not when using a plastic model (β = 0.08, P = 0.318). A non-significant difference was observed between the modalities in terms of knowledge test performance (d = 0.39, P = 0.052); however, mixed reality was more engaging (d = 0.59, P = 0.005) and learners were more confident in the information they learned compared to using a physical model (d = 0.56, P = 0.007). Overall, these findings suggest that spatial ability is more relevant in virtual learning environments, where the ability to manipulate and interact with an object is diminished or abstracted through a virtual user interface.  相似文献

Young boys' ‘underachievement’ and their disaffection with learning continue to dominate education agendas [Francis, B. 2006. “Stop That Sex Drive.” Times Educational Supplement 30; Peeters, J. 2007. “Including Men in Early Childhood Education: Insights from the European Experience.” NZ Research in Early Childhood Education, 10.

In recent years, there has been an eruption of government policy making and public discourse in England [Moran, L. 2011.

Accessed January 10, 2014. http://www.parity-uk.org/Briefing/BoysEducPaperRev1b.pdf] calling for more men to transform young lives by working in the 0–8 sector and acting as male role models in an attempt to narrow the ‘attainment gap’. This paper critically explores the perceived qualities/characteristics of men who seemingly serve as ‘male role models’ by reporting on select doctoral research findings which sought to investigate the ambiguities of the male role model from the perspective of men who work in the 0–8 sector. Research participants were asked to identify the qualities/characteristics that they felt ‘male role models’ should exhibit for young boys in the early years (0–8). The qualities/characteristics identified were categorised by research participants as being ‘masculine’ (e.g. diplomatic), ‘feminine’ (e.g. caring) or ‘natural’ (meaning authentic). Whilst research evidence suggests that male role models will present a diverse range of personal and professional qualities/characteristics, it is argued that these are likely to be shaped by not only the needs and circumstances of the children that the ‘male role model’ comes into contact with, but also the expectations of others, e.g. parents/carers and staff. This paper argues that there is a real tension between those qualities/characteristics of the male role model that are created as a result of their personality/individual beliefs and those which are anticipated or enforced by others.  相似文献

Home Economics (HE) teachers can have a central role in teaching sustainable development (SD) to young adolescents through everyday household management and the promotion of personally and globally sustainable well-being. How well the teachers cope with this task is not well known. The objective of this study was to survey Finnish HE teachers' perceptions of their current practice, coping, and future intentions in terms of teaching SD. Enablers and inhibitors to carrying out this task were further investigated. Findings from this survey suggest that HE teachers have adopted sustainability at a personal level, but often lack the resources and incentives to teach it. Ways to promote cross-curricular projects and wider integration of SD into HE are discussed.  相似文献
