Effectiveness of Physical Activity Interventions for Preschoolers: A Meta-Analysis

Purpose: The purpose of the meta-analysis was to examine the effectiveness of physical activity interventions on physical activity participation among preschoolers. A secondary purpose was to investigate the influence of several possible moderator variables (e.g., intervention length, location, leadership, type) on moderate-to-vigorous physical activity (MVPA). Method: Nine databases were systematically searched for physical activity interventions. Studies were included if they contained statistics necessary to compute an effect size (ES), were written in or translated into English, examined physical activity in preschoolers, incorporated a physical activity intervention, and targeted preschool-aged children. Fifteen studies satisfied these criteria. ESs were calculated using a random-effects model. Results: Results indicated that overall, interventions had a small-to-moderate effect on general physical activity (Hedges g = 0.44, p < .05, n = 73 ESs) and a moderate effect on MVPA (Hedges g = 0.51, p < .05, n = 39 ESs). The greatest effects for MVPA were identified for interventions that were less than 4 weeks in duration, were offered in an early-learning environment, were led by teachers, involved outdoor activity, and incorporated unstructured activity. Conclusions: This meta-analysis provides an overview and synthesis of physical activity interventions and highlights effective strategies for future interventions aimed at increasing physical activity levels among preschoolers.

Well-being in post-primary schools in Ireland: the assessment and contribution of character strengths

Enhancing the well-being of primary and post-primary students is one of the priorities of the Department of Education and Skills in Ireland. Whilst interventions are being implemented across the board, little is known about the current levels of adolescents’ well-being. Drawing from research on positive education, in the current study well-being was assessed amongst 2822 adolescents, aged 12–19 in Ireland, using the PERMA profiler [Butler, J., and M. L. Kern. (2016). “The PERMA-Profiler: A Brief Multidimensional Measure of Flourishing.” International Journal of Wellbeing 6 (3): 1–48. doi:10.5502/ijw.v6i3.526] and “VIA-Youth Survey” [VIA Character (2014). http://www.viacharacter.org/www/Research-Old2/Psychometric-Data-VIA-Youth-Survey]. Mann–Whitney U-test and multiple regression analyses were conducted in the examination of age and sex differences in students’ well-being scores, and the prediction of the contribution of character-strength-development to well-being. The results showed that students’ well-being decreased steadily from the first year, through to the middle and senior years of post-primary school. Furthermore, in comparison to males, females reported lower levels of well-being across the board, and higher levels of negative emotions and loneliness. Finally, the underuse of character strengths predicted lower levels of well-being in Irish schools. Implications for practice include the importance of customising well-being programmes across different schools and age groups, as well as the potential for the incorporation of psychological tests to evaluate the effectiveness of such interventions.     

俚语和成语,让你走出英语学习的黑暗

[接上期]Should Teachers Teach Naughty Words?After years of presenting to numerous teachers and leading discussion groups, I have found that the vast majority of teachers feel that familiarizing students with slang, idioms and even some vulgarities is much more desirable than having students pick up this type of language haphazardly on the street.     

Constructing Dysfunction: News Coverage of Teenagers and Social Media

Cultural storytellers such as journalists play a meaningful role in shaping how adults think about the role that social media play in teenagers’ lives. To better assess what adults might be learning, we employed a critical, qualitative approach to examine how contemporary news media constructed cultural understandings of teens’ relationship with social media. Our analysis of 339 print and online news articles from 2013–2014 found that the news media constructed a mediated reality that placed dysfunction as the defining characteristic of teens’ relationship with social media. The news articles consistently positioned teenagers and social media as at odds with one another, entwined in an unhealthy, frequently dangerous union. Discussions of the self-expressive, creative, and communicative practices of teen social media users were undermined or absent altogether. Altogether, the coverage created a mediated reality that denied teenage agency and obscured the diversity of teenagers’ experiences and social media practices.     

Re/conceptualising time and temporality: an exploration of time in higher education

ABSTRACT

In this paper we deconstruct hegemonic conceptions of time in higher education. Drawing on a recent project, we argue that limiting assumptions about time dominate notions of student capability and prospects of success. The paper reveals how the conceptualisation of time is constituted within a framework that individualises and decontextualises difficulties. Within this frame, socio-cultural elitism is left largely unchallenged, with many students left out and misrecognised as purely lacking capability and commitment. Rethinking simple distinctions between ‘time’ and ‘temporality’, we consider ways to broaden understandings to enable a more inclusive and ‘inventive’ system. We apply a Foucauldian analysis to argue that we co-construct the future in the very ways that we react to the present and think about the past. We must recognise that the way we work in the present is how we create the future. Our everyday actions, assumptions and reactions re/produce our futures.     

Wooden dolls and disarray: rethinking United States’ teacher education to the side of quantification

ABSTRACT

According to the 2013 report by the National Council on Teacher Quality (NCTQ), most teacher education programs are failing in the United States. These programs, NCTQ insists, are not preparing new teachers with sufficiently ‘scientific’ methods and are, in the process, failing to properly train prospective teachers how to ‘lead the classroom’ (p. 2). In the deficit discourses employed by NCTQ, teacher education programs have become a cesspool of ‘mediocrity’ (p. 1) where the overall findings ‘paint a grim picture of teacher preparation in the United States’ (p. 17). We actually agree that things are grim, but for very different reasons and in very different spaces. Using NCTQ’s ‘Teacher Prep Review: A Review of the Nation’s Teacher Preparation Program’ as an entryway, the authors argue that the report typifies not only an alarmist approach usually found in conservative attempts at social policy and reform, but also further reifies quasi-empirically based research as the best (indeed the only) method by which to measure effective teacher education programs. The authors deconstruct the taken-for-granted assumptions within the NCTQ text, challenging quantification as a research/policy paradigm while arguing for the value of newly imagining educational possibility through risk and creation.     

Towards a collaborative methodology: An ethnography of widening educational participation

This paper examines my attempts to develop a collaborative methodology, and critically considers the limitations and possibilities of this approach. It draws on a small-scale ethnography of widening educational participation undertaken for my doctoral degree. I worked with a group of access students in a UK further education college to develop the methods and methodology, to identify research questions and key areas of focus and, to a lesser extent, to analyse the data. Post/structural analytical tools enabled co-participants to deconstruct hegemonic neo-liberal discourses of widening participation. Feminist theory enabled the refashioning of radical discourses that are concerned with destabilising unequal relations of power in research and in education. In the paper I consider issues of power, research relationships, author-ity, reflexivity and ethics in collaborative methodology.
