ABSTRACT

Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall.  相似文献

Biomechanics and visual-motor control: how it has, is, and will be used to reveal the secrets of hitting a cricket ball   总被引：1，自引：0，他引：1  

Sarpeshkar V  Mann DL 《Sports biomechanics / International Society of Biomechanics in Sports》2011,10(4):306-323

Cricket batting is an incredibly complex task which requires the coordination of full-body movements to successfully hit a fast moving ball. Biomechanical studies on batting have helped to shed light on how this intricate skill may be performed, yet the many different techniques exhibited by batters make the systematic examination of batting difficult. This review seeks to critically evaluate the existing literature examining cricket batting, but doing so by exploring the strong but often neglected relationship between biomechanics and visual-motor control. In three separate sections, the paper seeks to address (i) the different theories of motor control which may help to explain how skilled batters can hit a ball, (ii) strategies used by batters to overcome the (at times excessive) temporal constraints, and (iii) an interpretation from a visual-motor perspective of the prevailing biomechanical data on batting.  相似文献

Closing the Gaps and Filling the STEM Pipeline: A Multidisciplinary Approach     

Peggy Doerschuk  Cristian Bahrim  Jennifer Daniel  Joseph Kruger  Judith Mann  Cristopher Martin 《Journal of Science Education and Technology》2016,25(4):682-695

There is a growing demand for degreed science, technology, engineering and mathematics (STEM) professionals, but the production of degreed STEM students is not keeping pace. Problems exist at every juncture along the pipeline. Too few students choose to major in STEM disciplines. Many of those who do major in STEM drop out or change majors. Females and minorities remain underrepresented in STEM. The success rate of college students who are from low-income background or first-generation students is much lower than that of students who do not face such challenges. Some of those who successfully complete their degree need help in making the transition to the workforce after graduation. A program at Lamar University takes a multidisciplinary approach to addressing these problems. It is designed to recruit, retain and transition undergraduates to careers in STEM, focusing its efforts on five science disciplines and on these “at-risk” students. The program was supported by a 5-year grant from the National Science Foundation and is supported through August 31, 2016 by Lamar University and a grant from ExxonMobil. A formal assessment plan documents the program’s success. The program received an award from the Texas Higher Education Board for its contributions towards Closing the Gaps in Higher Education in Texas. This paper describes the program’s theoretical framework, research questions, methods, evaluation plan, and instruments. It presents an analysis of the results achieved using these methods and implications for improvements to the program resulting from lessons learned.  相似文献   

Seeing in the Dark: Embodied Cognition in Amateur Astronomy Practice     

Flávio S. Azevedo  Michele J. Mann 《学习科学杂志》2018,27(1):89-136

We add to research on embodied cognition by investigating the observational practices of amateur astronomers. Specifically, we take an interactionist perspective and examine how the body is recruited, moment by moment, as a resource for producing and communicating meaning during field activity. The data corpus is a set of ethnographic video records and field notes on the routines of a community of astronomers, especially small-group interactions during planning, searching for, observing, and confirming sight of a celestial target. Within this space, our analysis highlights how different modalities of embodied action and reasoning (gestures, tool use, gaze, touch, and others) were deployed and coordinated throughout the process of observing a celestial object and how those emerged in the transactions among participants. Our findings rehearse many issues and topics in the contemporary literature (e.g., gesturing for measuring or representationally) but also reveal important, novel forms of embodied action and reasoning in science, technology, engineering, and mathematics practices (e.g., training the eyes in averted vision and inscribing a celestial scene onto one’s hand). More broadly, these findings further affirm the power of interactionist analyses of knowing and learning while also surfacing areas in which expanded theorizing is needed to account for the full set of cognitive phenomena we observed.  相似文献   

Penguin Promises: encouraging aquarium visitors to take conservation action     

Judy Brenda Mann  Roy Ballantyne  Jan Packer 《Environmental Education Research》2018,24(6):859-874

This study investigates the impact of an innovative conservation action campaign called Penguin Promises implemented at uShaka Sea World in Durban, South Africa. Communication tools included interpretive signage, exhibits with and without animals, presentations, and personal interactions, along with a specially designed postcard, on which visitors could write a promise (pledge) to make a change in their daily lives to become more environmentally responsible. Visitors who completed a card were contacted a year or more after their visit and asked about the outcomes of their promise. The results (N = 316) showed that 49.4% of respondents could give an example of something positive they had done for the environment, that they attributed to the campaign. Based on the study, recommendations are provided for the design of effective visitor conservation action campaigns.  相似文献   

The effect of biofeedback training on affective regulation and simulated car-racing performance: A multiple case study analysis

Abstract

In this study, we wished to investigate the factors that determine the direction of the spin axis of a pitched baseball. Nineteen male baseball pitchers were recruited to pitch fastballs. The pitching motion was recorded with a three-dimensional motion analysis system (1000 Hz), and the orientations of the hand segment in a global coordinate system were calculated using Euler rotation angles. Reflective markers were attached to the ball, and the direction of the spin axis was calculated on the basis of their positional changes. The spin axis directions were significantly correlated with the orientations of the hand just before ball release. The ball is released from the fingertip and rotates on a plane that is formed by the palm and fingers; the spin axis of the ball is parallel to this plane. The lift force of the pitched baseball is largest when the angular and translational velocity vectors are mutually perpendicular. Furthermore, to increase the lift forces for the fastballs, the palm must face home plate.  相似文献   

Guiding Attention Aids the Acquisition of Anticipatory Skill in Novice Soccer Goalkeepers     

Donghyun Ryu  Seonjin Kim  Bruce Abernethy  David L. Mann 《Research quarterly for exercise and sport》2013,84(2):252-262

Purpose: The ability to anticipate the actions of opponents can be enhanced through perceptual-skill training, though there is doubt regarding the most effective form of doing so. We sought to evaluate whether perceptual-skill learning would be enhanced when supplemented with guiding visual information. Method: Twenty-eight participants without soccer-playing experience were assigned to a guided perceptual-training group (n = 9), an unguided perceptual-training group (n = 10), or a control group (n = 9). The guided perceptual-training group received half of their trials with color cueing that highlighted either the key kinematic changes in the kicker's action or the known visual search strategy of expert goalkeepers. The unguided perceptual-training group undertook an equal number of trials of practice, but all trials were without guidance. The control group undertook no training intervention. All participants completed an anticipation test immediately before and after the 7-day training intervention, as well as a 24-hr retention test. Results: The guided perceptual-training group significantly improved their response accuracy for anticipating the direction of soccer penalty kicks from preintervention to postintervention, whereas no change in performance was evident at posttest for either the unguided perceptual-training group or the control group. The superior performance of the guided perceptual-training group was preserved in the retention test and was confirmed when relative changes in response time were controlled using a covariate analysis. Conclusions: Perceptual training supplemented with guiding information provides a level of improvement in perceptual anticipatory skill that is not seen without guidance.  相似文献   

Parents’ views of an optimal school life: using Social Role Valorization to explore differences in parental perspectives when children have intellectual disability     

Glenys Mann  Karen Moni  Monica Cuskelly 《International journal of qualitative studies in education》2016,29(7):964-979

Children with disability continue to experience disadvantage in their school lives; thus, the question of what makes up an optimal school life, and whether this is different for children with disability, becomes critical. This paper reports on research into parental views about an optimal school life and the usefulness of Social Role Valorization theory as a framework for exploring this issue. Six focus group interviews were used to collect data from 30 parents. Children of a variety of ages, with and without disability, were represented. All groups were similar in the aspects they regarded as optimal in a child’s school life. These fell into five categories: being connected, growth, personhood, basic needs, and happiness. Despite this similarity across groups, there were some notable differences in the detail; for example, parents of children with disability had a stronger focus on children being wanted, high expectations, and being seen as an individual.  相似文献
