INTRODUCTION Veselago (1968) showed that if both the permit- tivity ε and the magnetic permeability μ of a material are negative, the propagation direction of an elec- tromagnetic (EM) wave will be opposite to its energy flow direction. Such media are called left-handed materials (LHMs) since the electric field E, magnetic field H, and wave vector k in these media form a left-hand triplet of vectors, instead of a right-hand triplet observed in conventional materials. For a long time, … 相似文献

Multiple-choice examination answer copying was indexed by a comparison of the numbers of items answered incorrectly, and in the same way, as adjacent and distant classmates. In Experiment I, which involved a regular university examination, significant copying did occur, did not differ from front to rear of the lecture hall, and appeared primarily among individuals seated next to one another. Copying was not related to the order in which the examinations were returned. Number correct was related to turn-in order in a U-shaped fashion. No significant copying appeared in a second experiment, where test performance did not contribute to course grade. 相似文献

Drawing on the work of Dewey, we present a view of science education from the perspective of art and aesthetics. This perspective
places a transformative, aesthetic experience at the forefront of educational objectives. Such experience involves the application
of learning in everyday contexts, expansion of perception, and development of an increased interest in science ideas and aspects
of the world illuminated by those ideas. We present a pedagogical model focused on fostering transformative, aesthetic experiences.
This model involves two general categories of instructional methods: (a) methods of crafting ideas out of concepts, and (b)
methods of modeling and scaffolding transformative, aesthetic experiences. We discuss how the methods comprising this pedagogical
model relate to established science education methods. 相似文献

University Choice: What Influences the Decisions of Academically Successful Post‐16 Students? 总被引:1,自引:0,他引:1
The questionnaire survey reported in this paper is part of an ongoing evaluation of the effect of a bursary scheme on recruitment to Cambridge University. It sought to identify factors that encouraged or discouraged highly successful A Level students from applying to Cambridge. Findings reveal three main dimensions associated with the decision to apply to Cambridge, the nature of the courses, the prestige of the university and anxiety about the application process combined with fear of failure. Further analyses showed that there were complex interactions between these three dimensions which governed the decision to apply to Cambridge. These findings are relevant to other prestigious universities. The availability of a bursary did appear to influence the decisions of those who were eligible, but its influence was not as great as some of the other factors. 相似文献
