Inter-participant variability in daily physical activity and sedentary time among male youth sport footballers: independent associations with indicators of adiposity and cardiorespiratory fitness

Participation in youth sport is assumed to promote and contribute towards more physically active lifestyles among children and adolescents. The aim of this study was to examine inter-participant variability in objectively measured habitual physical activity (PA) behaviours and sedentary time among youth sport participants and their implications for health. One-hundred-and-eighteen male youth sport footballers (Mean ± s = 11.72 ± 1.60) wore a GT3X accelerometer for 7 days. Average daily PA [min · day^?1, in light (LPA), moderate (MPA), vigorous (VPA) and combined moderate-to-vigorous (MVPA)] and sedentary time were calculated. Participants’ body mass index adjusted for age and sex (BMI–standard deviation score), per cent body fat (BF%), waist circumference and cardiorespiratory fitness were assessed. Results revealed that variability in daily PA behaviours and sedentary time (min · day^?1) was associated with BMI–standard deviation score [VPA (?), MVPA (?)], BF% [sedentary time (+), VPA (?), MVPA (?)], waist circumference [sedentary time (+), LPA (?)] and cardiorespiratory fitness [sedentary time (?), MPA (+), VPA (+), MVPA (+)]. Whilst sedentary time and MVPA were not related to health outcomes independent of one another, associations with markers of adiposity and cardiorespiratory fitness were stronger for sedentary time. Sedentary time was also significantly positively related to waist circumference independent of VPA. Results demonstrate inter-participant variability in habitual PA and sedentary time among youth sport participants which holds implications for their health. Thus, promoting PA and, in particular, reducing sedentary time may contribute towards the prevention of adverse health consequences associated with a physically inactive lifestyle for children and adolescents active in the youth sport context.     

Understanding Differences in Academic Effectiveness: Practitioners’ Views∗

As part of a large‐scale study of the ability of 94 secondary schools to promote academic achievement, case studies of six outlier schools were conducted and headteachers (principals) and their deputies were questioned about the processes of effectiveness. The analysis of their responses ‐ grouped by the performance of their school (measured by value added analyses of three years of public examination results) as effective, ineffective or mixed ‐ reveals considerable support for previously cited characteristics of effective schooling. Despite the limitations imposed by a reliance on the use of retrospective accounts, the study takes forward the field of school effectiveness in its search for generalisable findings and coherent theory.

     

Cultural diversity in science education through Novelization: Against the Epicization of science and cultural centralization

Science educators are confronted with the challenge to accommodate in their classes an increasing cultural and linguistic diversity that results from globalization. Challenged by the call to work towards valuing and keeping this diversity in the face of the canonical nature of school science discourse, we propose a new way of thinking about and investigating these problems. Drawing on the work of Mikhail Bakhtin, we articulate epicization and novelization as concepts that allow us to understand, respectively, the processes of (a) centralizing and homogenizing culture and language and (b) pluralizing culture and language. We present and analyze three examples that exhibit how existing mundane science education practices tend, by means of epicization, towards a unitary language and to cultural centralization. We then propose novelization as a way for thinking the opening up of science education by interacting with and incorporating alternative forms of knowing that arise from cultural diversity. © 2011 Wiley Periodicals, Inc.

Which do students prefer to evaluate their essays: Peers or computer program

The purpose of this study was to investigate problems and potentials of new technologies in English writing education. The effectiveness of automated writing evaluation (AWE) (MY Access) and of peer evaluation (PE) was compared. Twenty‐two English as a foreign language (EFL) learners in Taiwan participated in this study. They submitted their draft to MY Access, received feedback from this automated grading system and then made some revision. In addition to the AWE, they also had peer revision in writing class. Three issues, including how writers used the feedback from these two kinds of evaluation, what progress they made in writing and how they perceived these two kinds of evaluation, are discussed. Results showed that EFL learners in Taiwan generally opted for PE over AWE. These findings raise several relevant issues, including social learning, feedback strategies, computer anxiety and cultural impact.     

Defining the outcomes of teacher education: what's social justice got to do with it?

In the context of escalating criticism of university‐based teacher education across the world, a clear need exists for informed defence of the field and the profession as well as critical evaluation of both teacher education and schooling. This paper takes up the issue of the ‘outcomes question’ in this regard, arguing the case for a strong focus on social justice as the necessary complement to an ongoing concern with academic excellence and rigor. It argues the need for teacher educators and others to look closely at the different ways that educational outcomes are currently being defined and for these differences to be made more openly and widely available for criticism and discussion. The paper seeks to contribute to debate regarding the role and renewal of teacher education, in specific relation to widespread standards movements and the public good, and the conduct and governance of education more generally.     

Classroom justice: Perceptions of fairness as a predictor of student motivation,learning, and aggression

The present study examined the relationship between students’ perceptions of distributive and procedural justice in a college course and student motivation concerning the course, affective learning in the course, and aggression toward the course instructor. Although student perceptions of both distributive and procedural justice were positively correlated with student motivation and affective learning and negatively correlated with student aggression toward the course instructor, multiple regression analyses indicated that only perceptions of procedural justice predicted the three criterion variables at a statistically significant level while distributive justice perceptions did not. Implications and suggestions for future research in classroom justice are offered.     

Identification of gifted students with learning disabilities in a Response‐to‐Intervention era

The identification of children who are twice‐exceptional—those who are gifted and have concomitant learning disabilities (LDs)—has historically posed a number of challenges for school psychologists and other school personnel. With the reauthorization of the Individuals With Disabilities Education Act and the shift to the use of a Response‐to‐Intervention (RtI) model to identify students with LDs, the task of identifying those who are twice exceptional is even more daunting. This article proposes an integrated model for the identification of gifted children with LDs that blends standardized assessment methods with practices consistent with RtI. This balanced approach brings together the best of both worlds to more accurately identify twice‐exceptional students and better meet their educational needs. © 2010 Wiley Periodicals, Inc.     

Assessing the impact of the Graduate Certificate in Anatomical Sciences Instruction: A post‐degree survey

There are few graduate programs available for pursuing a doctorate in anatomy where students gain specific training in gross anatomy dissection and the responsibilities of a medical educator. In light of this fact, the University of Kentucky created a Graduate Certificate in Anatomical Sciences Instruction in 2006. This 12‐credit hour curriculum includes detailed training in gross anatomy and/or neuroscience courses, practicum experiences, a seminar class in pedagogical literature, and a course in educational strategies for the anatomical sciences. The award of certificate completion affirms that the candidate has demonstrated faculty‐supervised proficiency in anatomy dissection, instruction in anatomy topics, and teaching strategies for anatomy. Seventeen graduate students have earned the certificate since its inception; nine students accepted teaching positions in anatomy following their graduate training and currently nine certificate graduates have assistant (six) or associate (three) professor positions in academia. In 2016, an anonymous survey including Likert‐style and open‐ended questions was emailed to all certificate graduates. Graduates favorably responded (each question averaged 4.4 or greater out of 5) that the certificate increased their awareness of teaching‐faculty responsibilities, adequately prepared them for teaching‐related duties, and positively contributed toward their first employment. Graduates indicated that the lecturing and dissection experience, awareness of faculty responsibilities, and job preparation (e.g., teaching philosophy development) were the most helpful aspects of the certificate. These results indicate that the Graduate Certificate in Anatomical Sciences Instruction is viewed by its graduates and their employers as a valuable teaching credential that can be attained alongside a basic science degree.
