Physical Activity Practices in Elementary Schools and Associations With Physical Education Staffing and Training

Purpose: Authorities recommend that schools provide a variety of opportunities for students to obtain physical activity (PA) before, during, and after school. This study assessed the prevalence of several school PA practices—including measures of quantity and quality of physical education (PE)—in elementary schools and examined the associations of PA practices with school resources (PE staffing, training, and facilities). Method: Surveys were obtained from respondents in nationally representative samples of elementary schools from 2009–2010 to 2011–2012 (1,831 schools). Results: Few schools (20.8%) provided students with PE class every day, but most (76.3%) had an appropriate PE student-to-teacher ratio ( ≤ 25:1). Many schools (74.0%) offered 20 min of recess daily, but fewer than half offered organized opportunities for PA before or after school (e.g., sports). After controlling for demographics and school size, having a full-time PE teacher and requiring PE teachers to obtain PE-related continuing education (CE) were associated with PE practices such as offering ≥ 150 min of PE per week (for 3rd-grade students) and testing PE knowledge, skills, and fitness. Required CE was also associated with a higher likelihood of offering PA during the school day (i.e., activity breaks and PA outside of PE class) and before or after the school day (i.e., afterschool PA programs). Conclusion: Few schools offer a broad array of PA programming. However, PE staffing and CE are positively associated with many PA practices including those outside of PE, possibly indicating that PE staff serve a crucial role in promoting a whole-school PA-supportive environment.     

Lifestyles and gendered patterns of leisure and sporting interests among Irish adolescents

This paper strives to provide an insight into the multifaceted relationships that young people have, examining the social, cultural and institutional discourses, which shape their lives. We set out to discuss, from an empirical poststructuralist perspective, the way in which Irish adolescents write about the reality of their lives and privilege certain practices and forms of subjectivity. We are particularly interested in the role and significance of physical activity in the lives of young people, asking what institutional and cultural discourses are brought into play to construct particular identities and social practices associated with leisure and sporting interests. This paper focuses on a purposeful sample of 168 written narratives of Irish post-primary students (14–17 years of age), chosen to represent the gender of students, a range of rural and urban school locales from different geographic locations and single sex and co-educational schools. We focus on the inter-relationships between (1) family and friends; (2) community-localism and tradition; (3) commodification and globalisation; (4) popular culture; and (5) gendered patterns of leisure and sporting interests. The family is a strong focal point for these young people as are their friends and being part of a community. The young people (boys in particular) are significant consumers of ‘media sport’ and both girls and boys were knowledgeable of national and international politics. We also comment on the extent to which female and male adolescents negotiate, similarly or differently, culturally dominant discourses within physical activity and sport, with significantly more boys choosing to write about physical activity and sport in their narratives.     

Too much freedom and autonomy in the enactment of assessment? Assessment in physical education in Ireland

This paper sets out to outline current discussions in Ireland around teachers being responsible for assessing their own students’ work, and the subsequent impact such a perspective is having (or not) on the delivery and assessment of physical education in Ireland. Our intention is to contribute to assessment considerations, while acknowledging the nuances of the Irish education context, and the positioning of physical education within such nuances. This discussion is particularly timely given the very recent endorsement for the introduction of the new Leaving Certificate Physical Education as a full optional subject. We begin by discussing more specifically assessment in Irish primary and post-primary schools, drawing attention to the limited Irish assessment-related research being conducted in both contexts. We then explore assessment developments related to Irish primary physical education and post-primary physical education and compare the extent to which such developments are limited in comparison to international assessment interests and practices in physical education. We conclude with suggestions related to studying (pre-service) teachers’ and students’ exposure to assessment in order to understand how we could alter the balance of assessment purposes and uses in Irish schools.

Clapping with two hands: Bringing together local and outside knowledge for innovation in land husbandry in Tanzania and Ethiopia ‐ a comparative case study

Abstract

Promoting rural development in Africa involves learning to clap with two hands, that is to say, creating effective interaction between local knowledge and development initiatives, on the one hand, and the knowledge and initiatives of formal agricultural research and extension, on the other. Farmer innovators ‐men and women farmers who take their own initiative to change local agriculture ‐ are key allies in rural development, as shown by the experience of the ISWC programme in Africa. Focusing on Ethiopia and Tanzania, the authors describe how formal research and extension services are made aware of farmers’ innovative work and are encouraged to document the results, promote their spread, and support further development efforts by farmer innovators. A modified Participatory Technology Development (PTD) approach is thus emerging, which starts not with problem analysis but rather by linking up with local problem‐solving initiatives. While the learning process on this approach continues, dialogue has been initiated with policy‐makers with a view to incorporating the approach into regular government extension, research and training activities.     

An ecological analysis of infant neglect by adolescent mothers

To inform efforts to prevent child neglect, we investigated a wide range of risk factors that have been largely unexamined in relation to infant neglect, the most commonly occurring form of child maltreatment. Using an ecological model of child neglect, we assessed the influence of characteristics at the level of the child, the mother, the family, and broader childrearing contexts on adolescent mothers’ likelihood of being a perpetrator in a substantiated case of neglect against their firstborn infants (n = 383, M = 12 months). Several factors were associated with infant neglect by young mothers: median block income, low infant birth weight, maternal smoking, maternal childhood history of neglect and of positive care, intimate partner violence (IPV) perpetrated by either the mother or her partner, and maternal use of mental health services. In multivariate models, income, a maternal childhood history of positive care, IPV by either a mother or her partner, and mental health service usage made significant contributions to the odds that a mother neglected her infant. Our findings suggest that these factors have particular salience to policymakers’ and practitioners’ efforts to identify high risk families and to intervene during the earliest months of life to prevent child neglect.

A comparison of verbal output and receptivity in relation to attraction and communication satisfaction in interpersonal relationships

This study tested relationships among verbal output, behavioral receptivity, attraction, and communication satisfaction in a variety of longer and shorter term relationships of differing levels of liking. Two behaviorally referenced reports on others were developed to measure perceived behavioral output and perceived behavioral receptivity. The study tested hypotheses within the attraction paradigm. Results generally supported the notion of an important reinforcement value of high behavioral receptivity and moderate verbal output. Substantial proportions of highly verbal people appeared to be below average in receptivity.
