Negotiating the Contested Terrain of Equity-Focused Change Efforts in Schools: Critical Race Theory as a Leadership Framework for Creating More Equitable Schools     

Terry M. Pollack  Sabrina Zirkel 《The Urban Review》2013,45(3):290-310

Educational leaders attempting to enact equity-focused change in their schools are frequently met with fierce opposition by politically powerful parents whose children are well served by the status quo. The purpose of this conceptual article is to: (a) explore the utility of Critical Race Theory as a framework for helping K-12 school leaders anticipate and make sense of resistance to change efforts aimed at creating greater educational equity for underserved students, and (b) suggest ways that school leaders can more effectively engage in equity reforms in their schools. To do this, we examine a highly contested public debate over a recent equity-focused change effort at Berkeley High School (BHS)—a large, racially and socioeconomically diverse public school in Northern California. Using the events at BHS as an example, we argue that change efforts could be undertaken more effectively by: (a) identifying and addressing the underlying property interests up front, (b) anticipating how majoritarian narratives rooted in “colorblindness” and deficit thinking would be employed as a means for obscuring and maintaining unequal access to scarce resources, and (c) focusing on specific areas of interest convergence.  相似文献   

Redesign and initial validation of an instrument to assess the motivational qualities of music in exercise: The Brunel Music Rating Inventory-2

Abstract

In the present study, a measure to assess the motivational qualities of music in exercise was redesigned, extending previous research efforts (Karageorghis et al., 1999 Karageorghis, C. I., Terry, P. C. and Lane, A. M. 1999. Development and initial validation of an instrument to assess the motivational qualities of music in exercise and sport: The Brunel Music Rating Inventory. Journal of Sports Sciences, 17: 713–724. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). The original measure, the Brunel Music Rating Inventory (BMRI), had shown limitations in its factor structure and its applicability to non-experts in music selection. Redesign of the BMRI used in-depth interviews with eight participants (mean age 31.9 years, s = 8.9 years) to establish the initial item pool, which was examined using a series of confirmatory factor analyses. A single-factor model provided a good fit across three musical selections with different motivational qualities (comparative fit index, CFI: 0.95–0.98; standardized root mean residual, SRMR: 0.03–0.05). The single-factor model also demonstrated acceptable fit across two independent samples and both sexes using one piece of music (CFI: 0.86–1.00; SRMR: 0.04–0.07). The BMRI was designed for experts in selecting music for exercise (e.g. dance aerobic instructors), whereas the BMRI-2 can be used both by exercise instructors and participants. The psychometric properties of the BMRI-2 are stronger than those of the BMRI and it is easier to use. The BMRI-2 provides a valid and internally consistent tool by which music can be selected to accompany a bout of exercise or a training session. Furthermore, the BMRI-2 enables researchers to standardize music in experimental protocols involving exercise-related tasks.  相似文献   

The Health-Related Fitness Test Opinionnaire: A Pilot Survey     

Margaret J. Safrit  Terry M. Wood 《Research quarterly for exercise and sport》2013,84(2):204-207

We tested the hypothesis that quiet eye, the final fixation before the initiation of a movement in aiming tasks, is used to scale the movement's parameters. Two groups of 12 participants (N = 24) threw darts to targets in the horizontal and vertical axes under conditions of higher (random) or lower (blocked) target variability. Supporting our predictions, random practice and target changes in the vertical axis led to longer quiet eye duration than did blocked practice and target changes in the horizontal axis. Our data suggest that quiet eye is not simply a mediating factor in accuracy, but is responsive to the task's programming demands, being influenced by the necessity to reparameterize the movement from one trial to the next.  相似文献   

Yearly Changes in the Body Composition and Muscular Strength of High School Wrestlers

Abstract

The purpose of this investigation was to determine the yearly changes in body composition as well as absolute and relative isokinetic forearm flexion and extension strength of high school wrestlers. Evaluations of body composition (underwater weighing) were performed on 27 high school wrestlers prior to three consecutive seasons. In addition, isokinetic forearm flexion and extension strength values at 180°/s (Cybex II) were available for 20 of the subjects. The mean ages at the times of laboratory testing were 15.5 (± .5), 16.5 (± .5), and 17.5 (± .5) years. Repeated measures ANOVA or ANCOVA with Tukey post-hoc comparisons were used to locate significant (p<.05) differences across age for height, body weight, relative fat, body density, fat weight, fat-free weight, absolute muscular strength, and muscular strength covaried for body weight and fat-free weight. There were yearly increases in all variables except fat weight, forearm flexion covaried for fat-free weight and forearm extension covaried for fat-free weight. The results of this study indicated that the improved wrestling performance and the increase in weight classification which normally occurs during high school are, in part, a function of yearly changes in body composition and muscular strength.  相似文献   

Isokinetic Leg Flexion and Extension Strength of Elite Adolescent Female Track and Field Athletes     

Terry J. Housh  William G. Thorland  Gerald D. Tharp  Glen O. Johnson  Craig J. Cisar 《Research quarterly for exercise and sport》2013,84(4):347-350

Abstract

Sixty-two elite adolescent (age: 16.39 ± 1.62 yrs) female track and field athletes volunteered to be measured isokinetically for peak torque of the leg flexors and extensors. The sample included 16 throwers, 11 jumpers, 12 middle-distance runners (> 400 m), and 23 sprinters. A Cybex II isokinetic dynamometer was used to measure dominant leg strength at 180°/sec. One-way ANOVA revealed significant between group differences for absolute flexion and extension (Nm), extension/body weight (Nm/Kg), and extension/lean body weight (Nm/Kg). Scheffe post-hoc comparisons showed that, for absolute leg extension strength, throwers were stronger than middle-distance runners (by 54.4%), sprinters (35.6%), and jumpers (23.6%). For absolute leg flexion movements, throwers were stronger than middle distance runners (37.4%) and sprinters (32.1%). Jumpers had greater extension peak torque values than middle-distance runners relative to body weight (14.0%), and throwers were stronger than middle-distance runners for extension/lean body weight (14.9%)). No other comparisons were significant. However, when strength was expressed relative to body weight or lean body weight, there were few differences between events for flexion or extension. Given that absolute strength scores were correlated with body weight and lean body weight, peak torque/body weight or peak torque/lean body weight may be more sensitive than absolute values as indicators of underlying factors (such as training status or fiber type composition) responsible for the differences in muscular strength between groups.  相似文献   

A Methodological Consideration for the Determination of Critical Power and Anaerobic Work Capacity     

Dona J. Housh  Terry J. Housh  Sonja M. Bauge 《Research quarterly for exercise and sport》2013,84(4):406-409

Abstract

Laboratory research in motor learning has consistently demonstrated higher retention and!or transfer when practice occurs under conditions of high contextual variety (e.g., Lee &; Magill, 1983; Newell &; Shapiro, 1976; Shea of Morgan, 1979;). In the present study, an attempt was made to determine whether a contextual variety effect could be demonstrated in a standard physical education instructional setting. During practice trials on the long and short badminton serves, male and female subjects performed under either blocked (i.e., all trials of one serve followed by all trials of the other) or varied (i.e., alternating trials of long and short serves) conditions. Retention and transfer tests (i.e., using the service area opposite that employed during the practice phase) were administered at the end of the badminton unit. Although little difference was observed in the performance of the two groups during practice, alternating-trial subjects demonstrated significantly higher retention of the short serve and significantly higher transfer of both serves than blocked-trial subjects. The performance of male and female subjects was not differentially influenced by practice structure conditions. It was concluded that a practice schedule that requires performers to change their plan of action from trial to trial may facilitate the retention and transfer of motor skills in applied instructional settings.  相似文献   

A Proposed Test for Determining Physical Working Capacity at the Heart Rate Threshold     

Loree L. Wagner  Terry J. Housh 《Research quarterly for exercise and sport》2013,84(3):361-364

Abstract

Forty-four subjects were given an all-out run test on a motor driven treadmill. The times for attaining heart rates of 150, 160, 170, 180 beats per minute were recorded along with measurements of ventilation, oxygen uptake and carbon dioxide production. The correlations between heart rate times and the all-out run times increased with the heart rate, a correlation of .85 calculated at the rate of 180 beats per minute. Using criteria established by Balke, it was demonstrated that the 180 heart rate serves as a valid cut-off point in measuring circulorespiratory capacity under variable exercise stress conditions.  相似文献

Terry O’Brien  Philip Russell 《International Information and Library Review》2012,44(1):1-7

The authors of this paper provide an overview of the activities of the Irish Working Group on Information Literacy (WGIL) and its role in advancing a national policy for information literacy in the Republic of Ireland.The study focuses on the work of the group during its lifetime including the various activities, marketing and advocacy initiatives and some of the challenges and issues the group faced, in particular, the diversity of the Irish library and information sector and the lack of an integrated approach for information literacy development.The study presents the findings of the report produced by WGIL entitled Library Association of Ireland: Working Group on Information Literacy: Review of Cross-Sector Activity 2006–2008 and Initial Recommendations for Further Action which reviewed best practices and information literacy activities in the various LIS sectors in the Republic of Ireland during a two-year period. The key recommendation of this report is for the leadership of the Library Association of Ireland to develop a national information literacy strategy that advocates for the importance of information literacy as a lifelong and transferable skill.  相似文献
