Observations of youth football training: How do coaches structure training sessions for player development?

We used systematic observation tools to explore the structure (i.e., activity and inactivity) and sequencing (i.e., the types of activities used) of football coaching sessions in Australia following the implementation of a new National Curriculum. Youth soccer coaches (n = 34), coaching within the Skill Acquisition (U11–U13 n = 19) and Game Training (U14–U17 n = 15) phases of the Football Federation Australia National Curriculum participated. Participants were filmed during a regular coaching session, with systematic observation of the session undertaken to provide a detailed analysis of the practice activities and coach behaviours. Findings indicated a session comprised of Playing Form activities (40.9%), Training Form activities (22.3%), inactivity (31%), and transitions between activities (5.8%). Coaches prescribed more Training Form activities (e.g., individual (5.4%) and drills (15.1%)) early in the session and progressed to Playing Form activities (i.e., small-sided games (15.3%) then larger games (24.8%)) later in the session. Most inactivity reflected the players listening to the coach – either in a team huddle (9.9%) or frozen on the spot during an activity (16.5%). In addition, coaches generally spent over 3 min communicating to players prior to explaining and introducing an activity regardless of when in the session the activity was scheduled.     

Groin injuries in professional rugby league players: a prospective study

Altogether, 100 uninjured professional rugby league players were evaluated over a 2-year period. Their height, body mass, sum of skinfolds, girths and bone diameters were recorded. A Cybex 340 isokinetic dynamometer was used to determine peak torque, work, power, endurance ratios and peak torque ratios of the hip abductors and adductors (5 repetitions at 0.52 and 2.08 rad?·?s^??1; 20 repetitions at 3.66 rad?·?s^??1) and knee flexors and extensors (4 repetitions at 1.04 and 3.14 rad?·?s^??1; 30 repetitions at 5.22 rad?·?s^??1). Hip abduction and adduction were also assessed with the hip in external rotation. Discriminant function analysis was conducted on all predictor variables to develop a multivariate predictive model capable of classifying players with a high degree of accuracy into groups with and without a groin injury. The model consisted of eight variables and correctly classified 91.7% of the non-injured players and 90.5% of the injured players. The correct classification for the model as a whole was 91.4%. The aetiological factors identified as being related to injury of the groin musculotendinous unit included abduction and adduction-with-rotation peak torque, angle of adduction and abduction-with-rotation peak torque, strength ratio of hip muscle groups, bilateral difference in extension peak torque, femur diameter and body mass.     

An Analysis of Playground Surface Injuries

Abstract

The purpose of this study was to examine the development of skill competence and tactical sophistication during a games unit conducted following the features of sport education provided by Siedentop (1994). One team of six players was followed through a 30-lesson season of “Ultimate.” Using Gréhaigne, Godbout, and Bouthier's (1997) formula for an efficiency index, together with a number of other measures of skill and tactical competence, it was determined that these students made significant improvements in selection and execution dimensions of the game. Furthermore, lower skilled students did not feel marginalized within their teams and believed they had equal opportunities for improvement. The key reasons for developing competence in this setting were the sufficient length of the season to allow for significant practice opportunities and the consistent team membership throughout season, which allowed all players to develop a sense of usefulness. This curriculum model provides one way students can develop skills through a system of game playing, provided sport education units are structured to prevent the more skillful players from dominating the games.     

Pre-K Music and the Emergent Reader: Promoting Literacy in a Music-Enhanced Environment

Emergent literacy may be nurtured in an early childhood environment that integrates literacy experiences with meaningful music activities in which young children develop skills necessary for success in both areas simultaneously. Early childhood educators can develop the knowledge and skills needed to bring music into the classroom as an engaging and stimulating element of literacy education.     

Meeting the challenge of HIV and AIDS in the classroom

Contemporary early childhood teachers are facing new challenges as children who test HIV positive or who have AIDS enter the classroom. Providing appropriate health care and educational programs for these children is a major concern of teachers. This article presents a brief discussion of guidelines and issues that might be addressed in an in-service for teachers in general education to prepare them for a student with HIV or AIDS in their classrooms.     

Making Space for Consuming Practices

This empirically driven paper is about workplace learning with specific focus on the ‘work’ of consuming practices. By consuming we refer to the eating, and the drinking, and (at times) to the smoking that workers, in most organisations, do on a daily basis. Indeed, it is the quotidian nature of consuming, coupled with its absence from workplace learning research that make them noteworthy practices to explore. In using the term practice we draw on the recent tranche of practice based theorisations: notably Schatzki (1996, Organization Studies, 26(3), 465-484, 2005, Organization Studies, 27(12), 1863-1873, 2006) and Gherardi (Human Relations, 54(1), 131-139, 2001, 2006, Learning Organization, 16(5), 352-359, 2009). The paper frames consuming practices as ‘dispersed’ (general) practices and, illustrated through empirical data from multiple projects, we progressively outline how these contribute to the learning of ‘integrative’ (specialized work) practices. Our overall aim is to (re)position consuming practices from prosaic, to having much relevance for research on workplace learning.     

Dyscalculia and dyslexia

Conclusion It is our hope that more practitioners in the field of learning disabilities will include the diagnosis and treatment of dyscalculia as they work with children and older individuals. Although there is much more to be explored, we believe that our clinical experience indicates that information-processing deficits may be a contributory factor in the disability and thus warrant further investigation. Furthermore, we believe that insights gained in the treatment of specific language disability may be fruitfully applied in the treatment of dyscalculia. This paper is a condensed version of a presentation at the 29th Annual Conference of The Orton Society, November 1978, at Minneapolis, Minnesota.     

Arrows of time in early childhood

Three studies with 149 children were conducted to provide information about development of the perception of temporally unidirectional transformations, such as dropping blocks or breaking a cookie. Children 3.5 through 6.5 years of age compared forward and backward videotapes of events or made individual judgments of what would happen if the actions were attempted. Even children 3.5 to 4.5 years of age recognized the anomaly of backward versions of gravity and separation events. In addition, relatively few children predicted impossible transformations in the prediction task. The results show that young children, like adults, are sensitive to the unidirectional nature of varied transformations.
