This article presents a conceptual framework derived from institutional theory in sociology that offers two competing policy contexts in which charter schools operate—a bureaucratic frame versus a decentralized frame. An analysis of evolving charter school types based on three underlying theories of action is considered. As charter school leaders pursue new and different forms of schooling, they are challenged by well-established bureaucratic rules and norms that define what it means to be a legitimate school. Microlevel institution-building efforts, however, may represent viable alternatives to the institutional order of public education as charter school leaders attempt to achieve scale. 相似文献

We study the misconceptions about colour that most people hold, determining the general phenomenological laws that govern them. Concept mapping was used to combat the misconceptions which were found in the application of a test specifically designed to determine these misconceptions, while avoiding the possible misleading inductions that could have arisen from the use of everyday language. In particular, care was taken to avoid the distorting effect that the use of the verb ‘to be’ applied to coloured objects could have on the responses. The misconceptions found were shown to have an internal consistency in the form of authentic mini-theories (implicit theories). We compared experimentally the results of two different teaching methods applied to combat these misconceptions. This study was conducted with 470 undergraduates of the University of Extremadura. We analysed the persistence over time of their learning made to overcome those misconceptions. The students were divided randomly into an experimental group (EG) and a control group (CG). To combat their misconceptions, EG were taught following a method based on the use of concept maps, and CG were taught following traditional teaching methods. The results of a pre-test and a post-test were compared for the two groups, finding statistically significant differences. The results allowed the principal working hypothesis to be accepted—concept maps are learning tools which foster conceptual change and allow misconceptions to be eradicated via meaningful learning maintained over time, i.e. EG acquired a relative long-lasting gain in learning that was superior to that acquired by CG. 相似文献

In this article, the authors describe the ways in which a set of policies has had what seem to be extensive and long lasting effects precisely because these policies are coherently linked to larger dynamics of social transformation and to a coherent strategy that aims to change the mechanisms of the state and the rules of participation in the formation of state policies. They describe and analyze the policies of the 'Popular Administration' in Porto Alegre, Brasil but, more specifically, they focus on the 'Citizen School' and on proposals that are explicitly designed to radically change both the municipal schools and the relationship between communities, the state, and education. This set of polices and the accompanying processes of implementation are constitutive parts of a clear and explicit project aimed at constructing not only a better school for the excluded, but also a larger project of radical and thick democracy. The reforms being built in Porto Alegre are still in formation, but the authors argue that they have crucial implications for how we might think about the politics of education policy and its role in social transformation. 相似文献

The authors used the structural equation model (SEM) approach to test a model hypothesizing the influence of parental involvement on students' academic aptitudes, self-concept, and causal attributions, as well as the influence of the 3 variables on academic achievement. The theoretical model was contrasted in a group of 12- to 18-year-old adolescents (N = 261) attending various educational centers. The results indicate that (a) parental involvement had a positive and significant influence on the participant's measured characteristics; (b) causal attribution was not causally related to self-concept or academic achievement when the task involved finding causes for success, but, self-concept and causal attributions were found to be significantly and reciprocally related when the task involved finding causes accounting for failure; (c) self-concept was statistically and predominantly causally related to academic achievement, but not vice versa; and (d) aptitude and self-concept accounted for academic achievement, although the effect of self-concept was predominant. These results suggest that in adolescence, cognitive-affective variables become crucial in accounting for academic behavior. 相似文献

Education is experiencing a case of misplaced accountability, where an exclusive reliance on high stakes tests overlooks the more subtle judgments of teachers and professional educators and, because of its simplicity, passes as democratic. This article investigates the theoretical underpinnings of current accountability initiatives and draws upon extensive teacher interviews to reveal the practical aspects of accountability pressures in schools today. We provide a discussion of local teacher knowledge that exposes teachers' commitments to a deeper sense of successful education that is eclipsed by testing and that offers a richer resource for improving classrooms and educational outcomes. We provide a discussion of educational foundations and policy that rethinks democratic goals and encourages educationists to shift the current debate in order to make accountability truly democratic. This article suggests that the contemporary climate of accountability may be misplaced in its intentions. 相似文献

Restoring the spans of a historic bridge requires installing tensors to ensure the structural and mechanical stability of the rows of stones that form the resistant body of the bridge. Once the positions where the structure-crossing tensors should be installed have been determined, the entry and exit points of each drill hole must be marked on both sides of the bridge. However, the exit point of each drill hole is not visible from the entry point, making it impossible to drill precisely. Here, we present a method based on a calibrated system that combines precision topography with laser technology. Using this method, drill holes longer than 12 m can be achieved with centimetric precision. 相似文献

AbstractCurrently, direct empirical evidence exists about the amount of mechanical load that climbers apply to each finger during several hand grips specific to sport climbing, but not yet in a specific hanging position.The objectives of this study are a) to draw and build a solid and rigid support that simulates the real action of a hand grip in a hanging position in sport climbing, to enable the measurement of the mechanical load endured by the fingers in a hanging position and in addition, b) to describe the distribution of mechanical load among fingers as a function of the level of climbing during different hand grips in a hanging position.Thirty young male participants took part in the initial phase of reliability of the measurements, while another 64 male climbers participated in the subsequent study phase to check the relations between independent and dependent variables. The level of on sight climbing and the total practice experience were used to define the groups. The research task consisted of performing hanging positions on the created support in order to measure the mechanical load endured by the fingers in the three most characteristic hand grips in climbing (crimp, half crimp and slope). It has been concluded that the performance level of the climbers had no influence on the production of a pattern of differentiated finger mechanical load during the research task. 相似文献

A contemporary view of early childhood motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. However, there has been minimal research examining the relationship between motor development and the home. The present study addresses this gap with the goal of creating an innovative parental self-report instrument to assess the quality and quantity of factors (affordances and events) in the home that are conducive to enhancing motor development in children ages 18–42 months. Following initial face validity determination, expert opinion feedback and selective pilot testing, construct validity was examined using 321 Portuguese families. Factor analysis techniques were used to: (a) compare competing factorial models according to previous theoretical assumptions, and (b) analyze the fit of the preferred model. Of the five plausible models tested, the five-factor solution provided the best fit to the data. Reliability was established through the scale reliability coefficient with a value of .85. The findings of this study suggest that the Affordances in the Home Environment for Motor Development Self-Report is a valid and reliable instrument to assess how well home environments afford movement and potentially promote motor development. 相似文献

Official publications are aimed towards editing and spreading the messages created by governments and other bodies of the public domain. At the beginning, the aim of this activity is twofold: on the one hand, fulfilling the principle of publicity of the norms, as it constitutes a basis for the efficiency of those, and, on the other hand, fulfilling a general function of information about the activities of public authorities. As the action of government generalises, this function of communication between those governing and those governed has extended to other fields of activity, thus, free and pay materials, both printed and electronic, are published. 相似文献
