The Validity of the Tritrac-R3D Activity Monitor for the Assessment of Physical Activity in Children

Abstract

The purpose of this study was to evaluate the validity of the Tritrac-R3D Activity Monitor, a new instrument designed to improve assessments of physical activity. Comparisons were made with a heart rate monitor and with a Caltrac Activity Monitor. Thirty-five children (ages 9–11 years) were monitored on 3 different school days with all 3 instruments. The Tritrac was moderately correlated with the heart rate monitor (r =.58) and highly correlated with the Caltrac monitor (r =.88). By taking advantage of the minute-by-minute timing capability of the Tritrac and the heart rate monitors, it was discovered, that the correlations between these instruments were highest during free play situations (lunch/recess, recess, after school) and were lower when activity was more limited (class time) or structured (physical education). The ability of the Tritrac to assess activity on a minute-by-minute basis may greatly enhance its overall utility.     

Teaching within a Curricular Zone of Safety: School Culture and the Situated Nature of Student Teachers' Pedagogical Content Knowledge

Abstract

The purpose of this paper is to continue the theoretical delineation of the nature of pedagogical content knowledge. Two student teachers were observed teaching an elementary games and high school sport unit and interviewed in depth about their lessons, biography, pedagogical content knowledge, and aspects of the school culture. Data were analyzed by constant comparison and analytic induction. Trustworthiness was established through member checks and triangulation. In the high school, both student teachers tried to use extending and refining tasks, as they had in the elementary school. But, when confronted with aspects of the high school culture, both retreated to a curricular zone of safety relying on application tasks. This zone, the defining aspect of their pedagogical content knowledge of teaching sports, emerged from and was constituted by the relations among goals, capabilities, teaching, inadequate pedagogical content knowledge, and aspects of the school culture. It is argued that situated and cultural orientations contribute to psychological orientations currently used to delineate pedagogical content knowledge. A curricular zone of safety is offered as a concept that helped account for the emergence and persistence of particular ways of knowing content.     

Physiological Effects of Deep Water Running following a Land-Based Training Program

Abstract

The purpose of this study was to examine differences in knowledge representation and problem solutions in expert and novice youth baseball players. Ninety-four players in two age divisions, 7–8 years of age and 9–10 years of age, were assigned to three levels of expertise: high; average; and low skilled. Each subject participated in an interview session to elicit knowledge representation and solutions to five different defensive game situations. Interviews were transcribed and analyzed for content, solution to the problem, errors in problem solution, and qualitative trends. The frequency of advanced solutions to each of the five situations were analyzed in separate chi-square tests for age and expertise. Differences among the levels of expertise were found for the accuracy of solutions to three complex situations. Age was significant for only one situation. Patterns of knowledge content accessed during advanced and less advanced responses indicated both experts and novices were in a beginning stage of developing baseball knowledge structures. Errors in problem solutions indicated children had difficulty monitoring critical conditions and making correct inferences. Players' and teammates' ability to execute baseball skills seemed to influence the content and structure of tactical knowledge accessed during problem solution.     

The use of computers in K-12 schools in turkey

Through the determined efforts of MONE, more than one third of the existing 5,851 schools have at least one computer lab. It is clear that the number of computers in schools in Turkey will continue to increase.

Digital learning lives aims to describe a set of practices in school education and beyond that are well developed and based on digital technology. With rich examples from our digital lives, the author shows that digital natives should be able to go beyond spaces and places with which they are familiar. People closely interested in broadening the scope of digital learning and creativity should think of buying this. Gi‐Zen Liu

This book seeks to formalise approaches to e‐learning by ensuring that e‐resource design is evaluated and appropriately supported by evidence. The book is aimed at academics who design e‐learning systems and need to devise scholarly evaluation research to assess their success. If this book's likely to relate closely to what you do, I suggest you borrow a copy so you can assess it for yourself. John G Hedberg     

On the Need for Dionysian Education in Schools Today

Although much has been written about Friedrich Nietzsche's views on education over the years, and much has also been written about Dionysus, god of wine and ecstasy, very little attention has been given to the meaning of, and need for, Dionysian education. In this article, Sean Steel attempts to begin that project. Drawing Nietzsche's articulation of the Dionysian, Apollonian, and anti‐Dionysian into the orbit of broader scholarship on Dionysus, Steel invites readers to think about what a Dionysian education might look like in a modern‐day school setting, as well as to consider what challenges exist for the implementation of such a vision of education.     

THE ‘RADICAL’ NARRATIVE,POLITICAL THOUGHT AND PRAXIS

This article offers a methodological refinement to the radical narrative of media history and advocates an exploration of the ideological dynamics of media texts as a crucial component of their praxis. Focusing on early to mid nineteenth-century utilitarian theory and praxis as exemplified in newspapers and pamphlets such as the Westminster Review, the Examiner and Pamphlets for the People, the article offers a sophisticated ideological critique which is intended to augment radical analyses of media history. This analysis allows a more focused and precise account of the ways in which early proto-liberal reformers used the press in their political strategy. Despite the Philosophic Radicals Mill, John S. 1873. Autobiography, London: Longmans, Green and Dyer.  [Google Scholar] having democratic aspirations, the article identifies inherent paternalistic and oppressive components of this praxis which has their seeds in classical Greek political thought.
