What do teachers in the USA perceive as the significant goals and purposes of education? To what extent are these perceptions related to those advocated in the reform literature of the 1980s? Responses to a survey administered to 279 teachers in metropolitan Atlanta, Georgia are analyzed in this study. Findings indicate some areas of congruence between teachers and reformers. In areas where the reform literature is divided, especially with regard to educational purpose, teacher opinion is similarly divided. Teacher responses, however, also indicate some attempt to synthesize seemingly disparate views. To provide an expanded frame of reference, the article offers some preliminary findings based on John Goodlad's Teachers for Our Nation's Schools. The article concludes with commentary about the nature and likelihood of educational reform in the USA.  相似文献

Successful tutoring depends in part on child tutors’ ability to recognise and interpret accurately signals of misunderstanding by their tutees. Age- and gender-related differences were investigated in a study which exposed 80 children to a video-recorded episode involving a target child receiving ambiguous instructions in her attempts to move a model car along a designated route on a playmat roadway from one destination to another. The results showed that explicit, general and facial modes of displaying puzzlement by the target child were judged as equally powerful expressions of degree of puzzlement, but 8-10 year olds judged the target child as significantly more puzzled than did 7 year olds. Older children were also more likely to attribute the puzzlement of the target child to the ambiguous instructions than to her verbal or facial expression of puzzlement. Girls were generally more accurate than boys in judging facial expressions and less likely than boys to give wrong or alternatively ambiguous responses when given the opportunity to correct the video-recorded ambiguous instructions. The results throw some light on the developing sensitivities of boys and girls in recognising and attributing failures of understanding by other children.  相似文献

Participants were administered multiple measures of phonological awareness, oral language, and rapid automatized naming at the beginning of kindergarten and multiple measures of word reading at the end of second grade. A structural equation model was fit to the data and latent scores were used to identify children with a deficit in phonological awareness alone or in combination with other kindergarten deficits. Children with a deficit in phonological awareness in kindergarten were found to be five times more likely to have dyslexia in second grade than children without such a deficit. This risk ratio substantially increased with the addition of deficits in both oral language and rapid naming. Whereas children with one or more kindergarten deficits were at heighten risk for dyslexia, some of these children were found to be adequate or better readers. These results are discussed within a multifactorial model of dyslexia that includes both risk and protective factors.  相似文献

This research sought to answer two questions: (1) What are Utah junior and senior high school students' preferences and choices regarding science subjects? (2) Could preferences and choices be related to the type of school, age or gender? Two thousand students from grades six through twelve participated in this study. Findings show that zoology and human anatomy and physiology were most preferred. Ecology was least prefered. Topics in the physical sciences were also low. There was a trend among girls to prefer natural sciences such as botany while boys tended to prefer the physical sciences. Generally, students' choices were limited to those subjects presently taught in the formal school curriculum. They appeared unaware of the many science related subjects outside the texts or the approved course of study.  相似文献

公民教育的进展研究:发达国家的探索   总被引:1,自引:0,他引:1  
21世纪初,无论是在国家层面还是在国际范围,人们都开始对公民教育产生新的兴趣。越来越多具有多元文化的民主国家对作为民主公民教育基础的人权教育的国际共识、全球化进程所带来的统一性与多样性之间关系的冲突特征、许多民主的民族一国家对公民(特别是年轻人)的政治参与水平以及对种族主义倾向的反民主运动的忧虑等,都被看作是引进和加强公民教育的原因。一个由国际学者组成的研究小组,通过考察、研究为我们确认了多元文化的民主体系中公民教育在教学方面的一些重要原则、概念以及公民教育对学校课程的促进。发达国家在实践方面的经验显示,成功的公民教育要求一个清晰的政策框架和专业的教师培训等。  相似文献

An Erosion Model (EM) of employee turnover is introduced to explain the previously observed negative relationship between network centrality and employee turnover. The EM hypothesizes that social support moderates the centrality–turnover relation as those more active in the organization's social network experience less job strain due to esteem provided by work peers. Three EM hypotheses were supported using meta-analytic procedures with significant relations identified between centrality and turnover (k=5, r=.29), social support and centrality (k=7, r=.23), and social support and turnover intentions (k=17, r=.35). Future research for EM expansion and practical applications are proposed.  相似文献

This study examined the unique effects of three forms of enacted (i.e., received) support (emotional, unpaid assistance, financial) on well-being and tested the potential mediating role of perceived control. The analysis was based on a national sample collected through the second wave of the Midlife in the United States (MIDUS) survey conducted in 2004–2006. Findings revealed emotional support exhibited a positive effect direction on well-being, while unpaid assistance and financial support both showed negative effect directions. Perceived control was found to fully mediate the relationships between all three forms of enacted support and well-being: Emotional support boosted well-being through higher perceived control, while unpaid assistance and financial support reduced well-being through lower perceived control. Findings provide evidence that effects of social resources on well-being are mediated through psychological resources.  相似文献

This article introduces a theoretical framework that can serve as a conceptual basis for media economics research of the development of media industries. The framework incorporates dynamic expansion and contraction processes and the constant interaction between strategy, structure, and government policy. The focus in this article is on strategic behavior of firms in the communications industry. I posit that these organizations are part of a system of organizations. As a part of this system the communications firm changes and affects the structure of the system, but at the same time the organization is affected by this same environment. The capability of media organizations to develop, augment, structure, and adapt a bundle of internal and external competencies is the central organizing concept.  相似文献

Fault tolerance of cooperative interception using multiple flight vehicles   总被引:1,自引:0,他引:1  
Cooperative interception of a moving target by multiple vehicles is studied. The main contributions of research work presented in this paper include: (1) cooperative interception is achieved for multiple vehicles to reach the target simultaneously at a finite time, by proposing and solving for a novel finite-time consensus problem and (2) in addition, the cooperative interception is investigated with tolerance of actuator or network failures, where novel fault tolerant consensus protocols are proposed to address actuator failures (or loss of effectiveness) and network failures, respectively. The maximum fault tolerance against network failures can be estimated. Simulations of a three-against-one interception case are presented to demonstrate the effectiveness of the proposed design approaches.  相似文献
