Teacher perceptions of a physical education statewide assessment program     

Rink J  Jones L  Kirby K  Mitchell M  Doutis P 《Research quarterly for exercise and sport》2007,78(3):204-215

A statewide program assessment was established to make positive change in physical education school programs in South Carolina. Reform efforts depend both on balancing accountability for change and teacher support for change (Odden &Anderson, 1986). The purpose of the study was to determine teacher perceptions of the South Carolina Physical Education Assessment Program and its effects across six related themes including: changes in teaching and learning, changes in curriculum and instruction, teacher awareness of the assessment program, teacher support for the program, work place conditions, and the advocacy role of the program. It was also the purpose of this study to determine if the survey responses were in any way related to teacher and school variables. The overall results of the study indicated positive change and support for the assessment program, supporting the viability of the standards, assessment, and accountability reform effort to positively impact physical education programs.  相似文献   

Leadership and Leader Behavior in Counseling: Neglected Skills     

Louis Vincent Paradise  Peggy T. Ceballos  Stephanie Hall 《International journal for the advancement of counseling》2010,32(1):46-55

Leadership and leader behavior are important topics for any professional discipline. However, these issues have been neglected throughout the entire short history of counseling. Despite the fact that many counselors attain various leadership positions, little attention has been paid to training for leadership. While much has been written about the various roles of counselors, leadership and the behavior of leaders are rarely the focus. It is our contention that counselors, because of their unique training, can be effective leaders in a wide variety of settings. This article argues for a greater emphasis by counselor education on the role of counselor as leader.  相似文献   

Graduate students' administration and scoring errors on the Woodcock‐Johnson III Tests of Cognitive Abilities     

Erica Ramos  Vincent C. Alfonso  Susan M. Schermerhorn 《Psychology in the schools》2009,46(7):650-657

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the administration and scoring of the Woodcock‐Johnson III Tests of Cognitive Abilities (WJ III COG). Data from 36 graduate students across 108 test records revealed a total of 500 errors across all records. Further analyses indicated three frequently occurring errors, including the use of incorrect ceilings, failure to record errors, and failure to encircle the correct row for the total number correct. The results of this study may be used to inform training programs so that appropriate steps can be taken to decrease the number of examiner errors on the WJ III COG and similar cognitive test batteries. © 2009 Wiley Periodicals, Inc.  相似文献   

Looking at Eye Gaze Processing and Its Neural Correlates in Infancy—Implications for Social Development and Autism Spectrum Disorder     

Stefanie Hoehl  Vincent M. Reid  Eugenio Parise  rea Handl  Letizia Palumbo  Tricia Striano 《Child development》2009,80(4):968-985

The importance of eye gaze as a means of communication is indisputable. However, there is debate about whether there is a dedicated neural module, which functions as an eye gaze detector and when infants are able to use eye gaze cues in a referential way. The application of neuroscience methodologies to developmental psychology has provided new insights into early social cognitive development. This review integrates findings on the development of eye gaze processing with research on the neural mechanisms underlying infant and adult social cognition. This research shows how a cognitive neuroscience approach can improve our understanding of social development and autism spectrum disorder.  相似文献   

Extracting the hydrodynamic resistance of droplets from their behavior in microchannel networks     

Vincent Labrot  Michael Schindler  Pierre Guillot  Annie Colin    Mathieu Joanicot 《Biomicrofluidics》2009,3(1)

The overall traffic of droplets in a network of microfluidic channels is strongly influenced by the liquid properties of the moving droplets. In particular, the effective hydrodynamic resistance of individual droplets plays a key role in their global behavior. Here we propose two simple and low-cost experimental methods for measuring this parameter by analyzing the dynamics of a regular sequence of droplets injected into an “asymmetric loop” network. The choice of a droplet taking either route through the loop is influenced by the presence of previous droplets that modulate the hydrodynamic resistance of the branches they are sitting in. We propose to extract the effective resistance of a droplet from easily observable time series, namely, from the choices the droplets make at junctions and from the interdroplet distances. This becomes possible when utilizing a recently proposed theoretical model based on a number of simplifying assumptions. Here we present several sets of measurements of the hydrodynamic resistance of droplets, expressed in terms of a “resistance length.” The aim is twofold: (1) to reveal its dependence on a number of parameters, such as the viscosity, the volume of droplets, their velocity as well as the spacing between them. At the same time (2), by using a standard measurement technique, we compare the limitations of the proposed methods. As an important result of this comparison, we obtain the range of validity of the simplifying assumptions made in the theoretical model.  相似文献   

The Internet Backbone and the American Metropolis   总被引：19，自引：0，他引：19  

Mitchell L. Moss  Anthony M. Townsend 《The Information Society》2000,16(1):35-47

Despite the rapid growth of advanced telecommunications services, there is a lack of knowledge about the geographic diffusion of these new technologies. The Internet presents an important challenge to communications researchers, as it threatens to redefine the production and delivery of vital services including finance, retailing, and education. This article seeks to address the gap in the current literature by analyzing the development of Internet backbone networks in the United States between 1997 and 1999. We focus upon the intermetropolitan links that have provided transcontinental data transport services since the demise of the federally subsidized networks deployed in the 1970s and 1980s. We find that a select group of seven highly interconnected metropolitan areas consistently dominated the geography of national data networks, despite massive investment in this infrastructure over the study period. Furthermore, while prosperous and internationally oriented American cities lead the nation in adopting and deploying Internet technologies, interior regions and economically distressed cities have failed to keep up. As information-based industries and services account for an increasing share of economic activity, this evidence suggests that the Internet may aggravate the economic disparities among regions, rather than level them. Although the capacity of the backbone system has slowly diffused throughout the metropolitan system, the geographic structure of interconnecting links has changed little. Finally, the continued persistence of the metropolis as the center for telecommunications networks illustrates the need for a more sophisticated understanding of the interaction between societies and technological innovations.  相似文献
