The use of vacuum interrupters(VIs)as the current interruption component for switches,circuit breakers,reclosers and contactors operating at distribution voltages has escalated since their introduction in the mid-1950’s.This electrical product has developed a dominating position for switching and protecting distribution circuits.VIs are even being introduced into switching products operating at transmission voltages.Among the reasons for the VI’s popularity are its compactness,its range of application,its low cost,its superb electrical and mechanical life and its ease of application.Its major advantage is its well-established reliability.In this paper we show how this reliability has been achieved by design,by mechanical life testing and by electrical performance testing.We introduce the“sealed for life”concept for the VI’s integrity.We discuss this in terms of what is meant by a practical leak rate for VIs with a life of over 30 years.We show that a simple high voltage withstand test is an easy and effective method for monitoring the long-term vacuum integrity.Finally we evaluate the need for routine inspection of this electrical product when it is used in adverse ambient environments.  相似文献

Metacognition and Self-Regulation in James,Piaget, and Vygotsky   总被引：3，自引：3，他引：0  
This article investigates the intertwined constructs of metacognition and self-regulation as they emerge in the works and theories of James, Piaget, and Vygotsky. To coordinate this exploration, we use an interpretive framework based on the relation of subject and object. In this framework, James’s perspective on metacognition and self-regulation is aligned with the Self, Piaget’s with the other and object, and Vygotsky’s with the medium or agency of language. We explore how metacognition and self-regulation function within the realm of human behavior and development as described in the works of each of these theorists. Key questions or issues that emerge for current research are outlined, and the limitations and benefits of each theorist’s perspective vis-à-vis metacognition and self-regulation are discussed.  相似文献

We report an attempted replication of G. T. W. Patrick and J. A. Gilbert’s pioneering sleep deprivation experiment ‘Studies from the psychological laboratory of the University of Iowa. On the effects of loss of sleep’, conducted in 1895/96. Patrick and Gilbert’s study was the first sleep deprivation experiment of its kind, performed by some of the first formally trained psychologists. We attempted to recreate the original experience in two subjects, using similar apparatus and methodology, and drawing direct comparisons to the original study whenever possible. We argue for a strong influence of an ‘Americanized’ Wundtian psychology on Patrick and Gilbert, a claim supported biographically by their education and by their experimental methods. The replication thus opens interesting new perspectives, which are unlikely to be generated by any other historical approach.

This paper is grounded in a deep appreciation of Nel Noddings’ “ethics of care” as an important contribution to moral philosophy and moral education. We seek to offer some philosophical reflections that have the potential to strengthen this important alternative to mainstream ethics and to how moral education might be conceived and practiced differently. After identifying some ambivalence in Noddings’ own position toward abstract philosophy, and despite the practical reasons for this that we share, we then find grounds for pressing in this speculative direction, some of which indeed accord with Noddings’ own statements and philosophical concerns. To show how such further philosophical reflection upon her relational morality could help, we focus on elaborating a perspective on ontological issues that we find in the work of Thomas Hill Green, a 19th century idealist, and seek to show its compatibility with Noddings’ more pragmatic stance. A concluding point addresses, and dispels, a possible worry that the grand narrative structure of Green’s idealism might undercut Noddings’ aim of having an ethic that is melioristic and open.  相似文献

Previous studies with university students have shown that resource interdependence during cooperative dyadic work on texts produces two different dynamics in student interaction and learning. Working on complementary information produces positive interactions, but a good quality of information transmission is needed to foster student learning. Working on identical information produces a confrontation of viewpoints but also encourages a threatening social comparison of competence, which can be detrimental for learning. The aim of present study is to test the moderating role of a partner’s competence in two peer-learning methods by manipulating a partner’s competence through a confederate. Results indicate that a partner’s competence is beneficial when students work on complementary information while it is detrimental when students work on identical information.  相似文献

In this paper we explore the portrayal of the “authentic” past in children’s literature in Ghana, as well as the problems it poses for the achievement of the broader goal of moulding children to fit into tomorrow’s society. We look at two main aspects: the social and moral settings portrayed in selected books. The social order refers to the time and place in which the story is set, as well as the nature of social organization pertaining to this setting. The moral order denotes the moral and psychological implications of the physical and social environment. Based on these criteria, we examine some unsuccessful texts and contrast them with successful ones. Our aim is to explore how tradition, more broadly conceived, can be effectively used in children’s books in order to combine the goal of cultural preservation and transmission with other equally lofty ones such as stimulating children’s imagination, arousing and sharpening their perception, developing their sense of observation and critical thinking, and shaping their emotional potential.  相似文献

We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher’s conceptions of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when teaching science lessons. The data gathering procedures were interviews analyzed by means of cognitive maps and classroom observations. The results reflected Miguel’s relativist conceptions of the nature of science that were consistent with his constructivist orientation in learning and teaching. In the classroom, however, he followed a strategy of transmission of external knowledge based exclusively on teacher explanations, the students being regarded as mere passive receptors of that knowledge. Miguel’s classroom behavior was completely contrary to his conceptions, which were to reinforce the students’ alternative ideas through debate, and not by means of teacher explanation.  相似文献

This study examines how teachers’ use of affective strategies (voice intonation, dramatization, personal involvement comments) during the reading and discussion of books influence young children’s affective reactions (dramatization, personal engagement, language play comments). Twenty kindergarten teachers read four books, two fiction and two information ones (narrative/expository text). We found significant differences in both teachers’ affective presentation and young children’s affective reactions between fiction and information books, between the two fiction books but not between the narrative and expository text. A strong bi-directional relationship was found between teachers’ affective presentation of stories and young children’s affective reactions. In particular, teachers’ personal involvement comments prompted children’s personal engagement reactions, teachers’ reenactment was followed by children’s imitations of such reenactments and teachers’ voice intonation elicited children’s personal engagement comments. On the other hand, children’s use of paralinguistic cues and personal engagement comments reinforced teachers’ use of voice intonation and personal involvement comments. Finally, text features, such as rhyming, were followed by children’s language play.  相似文献

The ‘Green Classroom’ in the Botanical Garden of Ulm is an experiential learning forum outside school. Its educational concept is based on experimental learning and is geared towards expanding biological knowledge and developing positive attitudes towards small animals such as invertebrates and insects. The attitudes of 68 school students towards small animals, before and after they visited the ‘Green Classroom’, were assessed and the answers they gave in their questionnaires were compared with those of 60 students froma control group that was not yet exposed to this learning environment. Although the students spent only one morning in the ‘Green Classroom’, some of their attitudes towards small animals improved after their visit. These studies underscore the necessity for direct observation and familiarization of the environment including small animals such as invertebrates and insects for appreciating issues related to biodiversity and conservation.  相似文献

The paper by White in this issue of Interchange contains an interesting model for a global educational perspective based on the writings of Aurobindo and Pierre Teilhard de Chardin. White proposes a foundation for this new perspective based on the synthesis of Aurobindo’s and de Chardin’s theories of global, social, and conscious evolution. In our response we critique the author’s proposal from the perspective of the current challenges to social justice within the educational community. In particular the writings of Charles Darwin, Paolo Freire, Karl Marx, and Vivekananda (Aurobindo’s peer) are examined to present evolutionary and philosophical viewpoints on the origins and causes of inequity. We contend that no global multicultural perspective on education is possible unless we first address the fundamental inequities present within the socio-economic and educational structures that characterize the world today. Thus any attempt to introduce a “global educational agenda” within an educational institutional structure is bound to be problematic.  相似文献
