Explaining differences in the metabolic cost and efficiency of treadmill locomotion in children

The metabolic cost of locomotion at any given speed, when expressed per kilogram of body mass, is greater for children than for older individuals. Incomplete explanations for the age-related difference motivated this study, which used a multidisciplinary method to examine metabolic, kinematic and electromyographic data from three maturational groups of children. Thirty children aged 7-8 (n = 10), 10-12 (n = 10) and 15-16 (n = 10) years completed 4 min bouts of submaximal treadmill exercise at six speeds--two walking and four running--assigned in random order. Metabolic (net VO2), kinematic (total body mechanical power, energy transfer rates, stride rate) and electromyographic (co-contraction of agonist and antagonist muscles in thigh and leg segments) data were collected. Multiple regression analysis was performed with net VO2 or efficiency as the dependent variable and mechanical power, thigh and leg co-contraction, stride rate and age as independent variables. It was possible to explain up to 77% of the age-related variance in net VO2 and 62% of the variation in efficiency using combinations of these variables. Age was the best single predictor of both VO2 and efficiency. Co-contraction, possibly used to enhance joint stability, was an important component of the observed age-related differences, although mechanical power was not. Additional variance might be explained as specific growth-related factors affecting the metabolic cost of locomotion are identified, as mechanical work models improve, and as methods are developed to measure the effects of stored elastic energy and the metabolic cost of isometric muscle actions.

‘I'm going to feel stressed,but now I know how to handle it’: reducing test anxiety and improving student well-being at GCSE

Test anxiety has become a widespread issue in many contemporary societies, having a significant detrimental effect on the attainment, health and well-being of many young people. This paper evaluates a school-based, multimodal test anxiety intervention framework, ‘Every Little Helps’ (ELH), developed by educational psychologists and delivered to small groups of GCSE students (aged 15–16) in two secondary schools in the North West of England. A quasi-experimental, mixed methods approach was adopted. Findings suggest that ELH is helpful in reducing test anxiety amongst GCSE students. Participants report a range of helpful outcomes including an increased sense of control and competence through increased academic attainment, enhanced control of emotions and more helpful ways of thinking. Participants also report beneficial wider impacts as a result of being able to generalise learnt skills and techniques to other aspects of their lives. Implications for educational policy and practice and future research are considered.     

The Revolution Will Be Privatized: Teach For America and Charter Schools

This article examines the ways that the charter school movement is experienced and negotiated by educators who entered the profession through Teach For America (TFA). TFA’s impact has been significant in the larger educational trend towards market-based reforms and, in particular, the charter school movement. Analyzed through a critical theory lens that focuses on issues of power and on the ways individuals interact amid larger (and often distal) structural forces, the experiences of TFA corps members are situated within the larger changing context of education. Amid contested, fractured, and complex narratives about charter school reform, TFA’s idea of “relentless pursuit” shaped participants’ conceptions and actions around charter schools.     

The Effect of an Education Program for Mothers of Children with Autism Spectrum Disorder in Jordan

There are few support services for parents of children with a disability in Jordan. The present exploratory study investigated whether the provision of an education program in Jordan for mothers of children with Autism Spectrum Disorder increased mothers’ understanding of their child’s behaviour, improved the mothers’ coping skills, and reduced their stress levels. Following the education program, the mothers reported a statistically significant reduction in stress levels, an increase in coping skills, and an improvement in mother-child interaction. Compared to fathers, mothers’ stress levels were significantly higher and their coping skills were significantly lower. The outcomes have valuable implications for interventions for families with a child with ASD living in Jordan or in other Arabic countries.     

Is the environmental literacy of university students measurable?

We report the development and piloting of an evaluative instrument and process for monitoring the environmental literacy (EL) of undergraduate students in one large research-led university in New Zealand. The instrument addresses knowledge, affect and competencies in the general area of EL in line with this institution’s adoption of EL as a graduate attribute (or in a US context, a general-education learning outcome, and something to be fostered throughout a student’s education). The instrument and associated processes were designed to fit within conventional institutional mechanisms that manage student feedback on the quality of teaching. The instrument was tested with more than 600 students from more than eight programmes over the course of a year and its use stressed that students were anonymous within the survey. We conclude that evaluating (or in a US context, assessing) the extent to which students acquire EL is an achievable objective and is a reasonable expectation for any higher education institution that claims to foster this attribute.     

The Association of Objectively Determined Physical Activity Behavior Among Adolescent Female Friends

The purpose of this study was to examine the extent to which physical activity among adolescent female friends is interdependent. The participants were 318 adolescent girls with a mean age of 16.0 years (range: 15–18 years). Pedometry was used to assess physical activity over 4 days. The relationship between an individual girl and her first-nominated reciprocal friend's physical activity level was moderate (r = 0.45, 90% confidence interval = 0.31, 0.56), when the friendship was nonreciprocal it was trivial (r = -.06, 90% confidence interval = -.36. .25). Friends' physical activity levels explained between 27% and 32% of an individual's pedometer-determined physical activity level. Reciprocity of friendship is an important variable to consider when understanding the relationship between adolescent female friends' physical activity. When friendships are reciprocal, there is a stronger relationship between friends' physical activity.     

Research priorities for YouTube and video‐sharing technologies: A Delphi study

Online video‐sharing services, particularly YouTube, have gained an audience of billions of users including educators and scholars. While the academic literature provides some evidence that YouTube has been studied and written about, little is known about priorities for YouTube research. The study employed the Delphi method to obtain a consensus from experts about areas that are most in need of research in video‐sharing technology (particularly YouTube). An expert panel, identified from a comprehensive review of the literature, participated in a three‐round Delphi process involving two cycles of online questionnaires and feedback reports. Participants responded to the question, ‘What should be the research priorities in video‐sharing technologies (particularly YouTube) over the next 5 years?’ Seven research priority categories were identified and ranked in order of priority: (1) users, groups and communities; (2) teaching/learning; (3) social/political impact; (4) video creation/production; (5) legal/ethical; (6) media management; and (7) commercial interests.

The general and specific effects of educational programmes aimed at promoting awareness of and respect for diversity among young children

This article reports the findings of a mixed‐method evaluation of a pilot educational programme undertaken with six to seven year olds in a sample of primary schools in England with the aim of increasing their awareness of and respect for diversity through theatre, workshops and related teacher‐led classroom activities. The qualitative feedback from the teachers involved was extremely positive and encouraging and an analysis of the actual impact of the pilot programme on the children’s attitudes and awareness, using an experimental design, demonstrated some positive effects. In particular, the programme was found to increase the children’s general awareness of diversity and their ability to recognize instances of exclusion. While not a planned objective of the pilot programme, the evaluation also examined whether it had any effects on the children’s attitudes to specific differences, in this particular case racial differences. Interestingly, however, no evidence was found of any change in the children’s racial attitudes. With this in mind the article suggests that there is a need to distinguish between the general and specific effects of such educational programmes. The article considers the implications of this for future work in the area and also stresses the need to begin undertaking more thorough and rigorous evaluations of such initiatives.
