Viewing the school environment through multiple lenses: In search of school‐level variables tied to student achievement

The “No Child Left Behind” (NCLB) Act has made schools accountable for assuring adequate yearly progress of students. Therefore, it has become critical to identify school‐level variables that can be controlled to affect student achievement, especially given that, thus far, most school reform efforts have failed to significantly affect student achievement. This study identifies four theoretical constructs, three unique sets of empirical factors (one set for each group: students, teachers, and principals), and seven experiential themes that describe the middle school environment. However, none of these variables show any predictive relationships with achievement, which suggests current federal policies, such as NCLB, are inappropriate and unlikely to lead to improvements in science education in the USA. In addition, students, teachers, and principals were found to perceive the school environment in very different ways, indicating further investigation of student culture is needed to determine appropriate changes that might lead to real improvements in achievement. © 2006 Wiley Periodicals, Inc.

Working with the dense weave of cognitive and affective strands in the classroom

Language teaching is in a post-method age.This means that in the development of EFL/ESOL programmes and classroom practice,we are unlikely to find and implement a new method which will guarantee success in learning.As teachers,we work with an extensive and ever-changing repertoire of pedagogic     

Multicultural Counselor Training Experiences: Training Effects and Perceptions of Training Among a Sample of Predominately Hispanic Students

The effectiveness of multicultural training among a sample of predominately Hispanic counseling students was examined. The results of a series of 2‐factor repeated measures analysis of variance and follow‐up paired‐samples t tests suggest that multicultural training was effective in increasing students' multicultural competencies and in improving their cognitive racial attitudes. Students' affective racial attitudes were not changed. Students' perceptions of their multicultural training suggest that students from diverse racial/ethnic backgrounds may experience multicultural training differently and unique life experiences may help explain this difference. Counselor educators may wish to use a variety of training experiences to provide multicultural training that is effective across diverse student populations.     

Mechanical behaviour of natural turf sports pitches across a season

A study assessing the mechanical behaviour of six natural turf pitches of varying sporting level and surface construction was undertaken over a period of 10?months, spanning a sporting season (August 2010 to May 2011). Penetration resistance and shear resistance were measured with the GoingStick^?, impact hardness and surface energy absorption were measured with the 2.25?kg Clegg Impact Soil Tester and the Dynamic Surface Tester device, respectively. The two sand rootzone pitches were more resistant to deformation and less variable in their impact behaviour (impact hardness and energy absorption) through the season than the native soil pitches containing greater proportions of silt and clay. Greater consistency was shown for penetration resistance and shear resistance on one of the sand rootzone pitches, with the other behaving similar to the native soil pitches for these parameters. The sand rootzone surfaces exhibited greater (P?<?0.05) impact hardness than the native soil pitches in the winter period of the season (November to mid-March) compared to the beginning or end periods of the season, where data were statistically similar (P?>?0.05). The greater consistency of sand rootzone surfaces should be considered for the effect it may have on player and team performance, and injury potential. Analysis of data against Performance Quality Standard benchmarks indicated that all data on the sand rootzones exceeded preferred values for impact hardness, indicating these ranges may be obsolete for the modern elite natural turf surface.     

The influence of equipment variations on sliotar–hurley impact in the Irish game of hurling

The game of hurling is ranked as one of the fastest and most skilful field games in the world. It is played by a stick, hurley, made of ash wood and a ball, sliotar, made of a cork core or similar viscoelastic materials. Better standardisation of the game equipment requires analysing impacts to quantify precisely the effect of variations in equipment design on the resultant impact force at low and high striking speeds. Therefore, the purpose of the present study was to use a high-speed camera to (1) characterise the impact dynamics in term of impact force magnitude and duration, and (2) investigate whether a relationship exists between the game equipment and the magnitude of the impact force. An air cannon unit (ACU) test rig was set up to cause the sliotar to strike the hurley at predetermined speeds. A high-speed camera operating at 12,500 frames per second (fps) was used to capture 32 experimental impacts covering a range of sliotar and hurley brands, impact locations and impact speeds. The factor ??sliotar brand?? was identified as the most significant factor for the impact force among other main factors and two-factor interactions at a constant speed and it had a significant effect with up to 27?% difference between sliotar brands. It was demonstrated that, at higher impact speeds, the force?Cdeformation curves of the sliotar brands varied significantly, even though similar force?Cdeformation curves have been reported at quasi-static compression and similar COR values at low impact speeds using the standard free-drop test. This is the first known study to characterise the unique, highly non-linear and anisotropic sliotar?Churley impact using high-speed camera technology. It highlights the need for a tighter standard for sliotar materials and manufacturing to increase uniformity between different brands and strongly suggests that the standard free-drop test is not sufficient to characterise and compare game equipment.     

An Organizational Life Cycle Approach to Exploring the Elite Sport Legacy of Summer Olympic Host Nations: The Cases of China (Beijing 2008) and Australia (Sydney 2000)

Abstract

This paper investigates the elite sport legacies of hosting the Summer Olympics for China (Beijing 2008) and Australia (Sydney 2000). The classic organizational life cycle approach provides the conceptual framework for this retroductive study. The data for both cases are sourced from official publications, academic research, and documents from various government departments and organizations. Additional data are drawn from three semi-structured interviews with key Chinese stakeholders. The analysis provides clear evidence that governments and their stakeholders use the opportunities afforded by a home Olympics to boost Olympic performance. China and Australia experienced a similar four-phase pattern of elite sport legacy life cycle: start-up, growth, maintenance, and decline. Both countries also shared many similar policy and management factors throughout each stage. An increased awareness of the sequential nature of elite sport legacy can help Olympic host countries make a more informed decision about their long-term strategies for elite sport success.     

Coworker knowledge sharing and peer learning among elite footballers: Insights from German Bundesliga players

This research focuses on coworker learning and knowledge sharing amongst elite footballers. The authors provide an in-depth understanding on how elite footballers learn from their peers and which channels are used to share their knowledge. The authors also analyze how peer learning impacts an elite footballer’s development and performance and to what extent elite football clubs actively support peer learning. Data were collected through semi-structured interviews with 12 elite footballers from first and second division German Bundesliga clubs. The findings demonstrate that peers are very important sources of knowledge for elite footballers. There are four main knowledge sharing channels: observing/imitating, peer exchange/peer communication, labor mobility and knowledge brokers. The findings highlight the positive impact of knowledge sharing on elite players’ development and performance and call for future (knowledge) management tactics to specifically use this untapped potential.     

Time-motion analysis of elite field hockey, with special reference to repeated-sprint activity

Limited information exists about the movement patterns of field-hockey players, especially during elite competition. Time-motion analysis was used to document the movement patterns during an international field-hockey game. In addition, the movement patterns of repeated-sprint activity were investigated, as repeated-sprint ability is considered to be an important fitness component of team-sport performance. Fourteen members of the Australian men's field-hockey team (age 26+/-3 years, body mass 76.7+/-5.6 kg, VO2max 57.9+/-3.6 ml.kg(-1).min(-1); mean+/-s) were filmed during an international game and their movement patterns were analysed. The majority of the total player game time was spent in the low-intensity motions of walking, jogging and standing (46.5+/-8.1, 40.5+/-7.0 and 7.4+/-0.9%, respectively). In comparison, the proportions of time spent in striding and sprinting were 4.1+/-1.1 and 1.5+/-0.6%, respectively. Our criteria for 'repeated-sprint' activity (defined as a minimum of three sprints, with mean recovery duration between sprints of less than 21 s) was met on 17 occasions during the game (total for all players), with a mean 4+/-1 sprints per bout. On average, 95% of the recovery during the repeated-sprint bouts was of an active nature. In summary, the results suggest that the motion activities of an elite field-hockey competition are similar to those of elite soccer, rugby and Australian Rules football. In addition, the investigation of repeated-sprint activity during competition has provided additional information about the unique physiological demands of elite field-hockey performance.
