Robert A. Davis 《Educational theory》2010,60(3):285-298
In this essay, Robert Davis argues that much of the moral anxiety currently surrounding children in Europe and North America emerges at ages and stages curiously familiar from traditional Western constructions of childhood. The symbolism of infancy has proven enduringly effective over the last two centuries in associating the earliest years of children's lives with a peculiar prestige and aura. Infancy is then vouchsafed within this symbolism as a state in which all of society's hopes and ideals for the young might somehow be enthusiastically invested, regardless of the complications that can be anticipated in the later, more ambivalent years of childhood and adolescence. According to Davis, the understanding of the concept of infancy associated with the rise of popular education can trace its pedigree to a genuine shift in sensibility that occurred in the middle of the eighteenth century. After exploring the essentially Romantic positions of Johann Heinrich Pestalozzi and Friedrich Fröbel and their relevance to the pattern of reform of early childhood education in the United Kingdom and the United States, Davis also assesses the influence of figures such as Stanley Hall and John Dewey in determining the rationale for modern early childhood education. A central contention of Davis's essay is that the assumptions evident in the theory and practice of Pestalozzi and his followers crystallize a series of tensions in the understanding of infancy and infant education that have haunted early childhood education from the origins of popular schooling in the late eighteenth century down to the policy dilemmas of the present day. 相似文献

Critiquing and adapting curriculum materials are essential teaching practices but challenging for many preservice teachers.
This study explores the use of educative curriculum materials—materials intended to support both teacher and student learning—to
help preservice elementary teachers develop their pedagogical design capacity for critiquing and adapting lessons. Preservice
teachers received educative supports highlighting pedagogical principles and rationales for those principles. When provided
with educative supports, most individuals attended to the principles targeted in the supports, engaged in an in-depth analysis
with regard to the principles, and used the rationales from the supports to justify their analyses. However, few continued
to do so in subsequent analyses when they no longer received support. Implications for science teacher education and curriculum
design are discussed. 相似文献

This paper is one of a pair that re-examines the evidence from a national initiative to train all teachers in England to bring them up to the level of newly qualified teachers, who are required to know when to use and when not to use information and communication technologies (ICT) in their professional practice. Reanalysis of data gathered for the 2004 evaluation uncovers the complexity of such professional development. The effectiveness of contrasting approaches to ICT-related teacher training was analysed using the national survey of 496 trainees and experts' reports on 11 of the 47 training providers. multilevel evaluation of professional development was shown to be robust for ICT teacher training, including a significant correlation between the views of experts and those of teachers. The presence of the middle level of 'organisational support and change' emerged as a particularly discriminating factor, indicating that higher-quality teacher training supports change in the classroom and in the school. Therefore, we recommend that all five of Guskey's levels be consistently adopted for the evaluation of ICT teacher training, and that research should also adopt a multilevel model. A second paper delves deeper to describe and contrast the highest and lowest-rated approaches to ICT teacher training. 相似文献

For the past three decades, Sanger’s method has been the primary DNA sequencing technology; however, inherent limitations in cost and complexity have limited its usage in personalized medicine and ecological studies. A new technology called “thermosequencing” can potentially reduce both the cost and complexity of DNA sequencing by using a microfluidic platform [Esfandyarpour, Pease, and Davis, J. Vac. Sci. Technol. B26, 661 (2008)]. To optimize the efficiency of the technology, finite element analysis was used to model the thermosequencing system by simulating the DNA incorporation reaction series and the resulting product concentration and heat production. Different models of the thermosequencing platform were created to simulate the effects of the materials surrounding the system, to optimize the geometry of the system, and to concentrate reaction heat into specific regions for detection in the real system. The resulting concentrations of reaction products were used to calibrate the reaction speed and to design the heat sensors in the thermosequencing technology. We recommend a modified gated structure for the microfluidic detection platform by using control valves and show how this new platform could dramatically improve the detection efficiency. 相似文献
