A symplectic eigensolution method in transversely isotropic piezoelectric cylindrical media     

徐新生 顾佥梁以德  郑建军 《浙江大学学报(A卷英文版)》2005,6(9):922-927

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse…  相似文献

Two cohorts of children from inner-city elementary schools were provided a tutoring intervention to help in their transition to new schools. Participants were third, fourth, and fifth grade children who were identified as having low-income status, evidencing lags on achievement tests, and experiencing stressful life events. The intervention involved an orientation program with twice weekly paraprofessional tutoring. Two and three year academic and sociometric follow-up data were collected. Those provided the intervention evidenced some improvements over time, and these changes were most prominent in the area of reading grades. Fewer significant findings were found on sociometric indices.  相似文献   

Enacting Informal Science Learning: Exploring the Battle for Informal Learning     

Andrew Clapham 《British Journal of Educational Studies》2016,64(4):485-501

Informal Science Learning (ISL) is a policy narrative of interest in the United Kingdom and abroad. This paper explores how a group of English secondary school science teachers, enacted ISL science clubs through employing the Periodic Table of Videos. It examines how these teachers ‘battled’ to enact ISL policy in performative conditions at the micro-scale, and how this battle reflected macro-scale epistemological and political considerations. Data from the study suggests that for some, ISL was low stakes as it was seen to have negligible impact upon performance data. As a result, there was some resistance towards enacting ISL and conflict between the formal and informal curriculum processes. Nonetheless, analysis indicates that the informants highly valued ISL despite the requirement for them to justify it over more formal and ‘effective’ approaches to learning science.  相似文献   

Student,home, and school socio-demographic factors: links to school,home, and community arts participation     

Marianne?Mansour  Andrew?J.?MartinEmail authorView author&#;s OrcID profile  Michael?Anderson  Robyn?Gibson  Gregory?Arief?D.?Liem  David?Sudmalis 《The Australian Educational Researcher》2016,43(2):221-244

This study explored the role of student (e.g., age, language background, gender), home (e.g., parent/caregiver education), and school (e.g., school type, size) socio-demographic factors in students’ school (e.g., in-school arts tuition, arts engagement), home (e.g., parent/caregiver–child arts interaction), and community (e.g., arts attendance, arts tuition) arts participation. The sample comprised 1172 elementary and secondary school students from 15 schools. Findings revealed that student and home socio-demographic factors were the most salient in predicting arts participation across school, home, and community contexts. Age, gender, and prior achievement were the key student socio-demographic factors, while parent/caregiver education and occupation were also associated with students’ arts participation. Implications for practice and intervention pertinent to young people’s arts participation are discussed.  相似文献   

There and Back Again: Exploring Teacher Attrition and Mobility with Two Transitioning Science Teachers     

Andrew Gilbert 《Journal of Science Teacher Education》2011,22(5):393-415

This study chronicled the professional journeys of two beginning science teachers. The focus of the research effort documents what brought them to science teaching and investigated their resulting career paths. Data artifacts for this instrumental case study approach included: interviews, written survey responses, personal communications and member checks. All data was transcribed and coded into emergent categories using a constant comparative analysis approach. The findings indicated that their decisions to enter and leave teaching were a complex mélange of issues that included career disposition, notions of isolation, overarching culture of the school, and future possibilities. However, most striking was their re-entry into teaching on a temporary basis after considerable time away from the classroom, which suggests that teachers develop a sense of agency regarding their career decisions. This may require researchers to reconsider how we view teacher decision-making within the context of teacher attrition and mobility. Implications for science teacher education indicate that some teachers may enter the profession considering teaching to be a transition into a different career path. Secondary science teachers may perceive multiple career options (beyond the classroom) based on their preparation and teaching experience. Further implications and possibilities for science teacher education are discussed.  相似文献   

WIDENING AND INCREASING POST-16 MATHEMATICS PARTICIPATION: PATHWAYS, PEDAGOGIES AND POLITICS     

Andrew Noyes  Geoff Wake  Pat Drake 《International Journal of Science and Mathematics Education》2011,9(2):483-501

This paper explores the potential impact of a national pilot initiative in England aimed at increasing and widening participation in advanced mathematical study through the creation of a new qualification for 16- to 18-year-olds. This proposed qualification pathway—Use of Mathematics—sits in parallel with long-established, traditional advanced level qualifications, what we call ‘traditional Mathematics’ herein. Traditional Mathematics is typically required for entry to mathematically demanding undergraduate programmes. The structure, pedagogy and assessment of Use of Mathematics is designed to better prepare students in the application of mathematics, and its development has surfaced some of the tensions between academic/pure and vocational/applied mathematics. Here, we explore what Use of Mathematics offers, but we also consider some of the objections to its introduction in order to explore aspects of the knowledge politics of mathematics education. Our evaluation of this curriculum innovation raises important issues for the mathematics education community as countries seek to increase the numbers of people that are well prepared to apply mathematics in science and technology-based higher education courses and work places.  相似文献   

Ministerielle Aufsichtskompetenz und Ersatzvornahme     

Manfred Novak 《Zeitschrift für Hochschulrecht, Hochschulmanagement und Hochschulpolitik: zfhr》2011,10(6):231-237

Die ministerielle Aufsichtskompetenz über das Organhandeln an Universit?ten hat im Zuge des Ausbaus der universit?ren Selbstverwaltung, seit dem UOG 1993, eine ma?gebliche Stellenwert?nderung erfahren. Diese beschr?nkt sich nicht auf die formale Zurücknahme der ministeriellen Aufsicht auf eine reine Rechtsaufsicht, sondern ist auch im inhaltlichen Konnex mit der vom UG intendierten neuen Selbstverantwortung der Universit?ten, bei Aufgabenerfüllung und Bestellungsakten, zu sehen. Dabei l?sst sich, hinsichtlich Gehalt und Selbstverst?ndnis ministerieller Verantwortung über die Universit?ten, im intentionalen Wechselspiel von Rücknahmepostulat und Determinierungswillen, eine nicht unbetr?chtliche Unbestimmtheit zwischen ministeriellem K?nnen, Wollen und Sollen bemerken.  相似文献   

What's in It for Me? Incentives,Learning, and Completion in Massive Open Online Courses     

Todd D. Reeves  Andrew A. Tawfik  Fortunata Msilu  Irfan Şimşek 《Journal of Research on Technology in Education》2017,49(3-4):245-259

This study investigated the distribution of incentives (e.g., certificates, badges) for massive open online course (MOOC) completion, and relationships between incentives and MOOC outcomes. Participants were 779 MOOC students internationally who participated in at least 303 different MOOCs offered by at least 12 providers. MOOC participants most commonly intended to receive, and in actuality received, free and paid course certificates of completion; other incentives (e.g., digital badges, postsecondary credits) were far less common. In addition, MOOC participants' intentions to receive both free and paid certificates were consistently and positively related to perceived learning and course completion, net other factors. (Keywords: massive open online courses, MOOCs, motivation, incentives, microcredentials, certificates of completion)  相似文献   

Study-service as a significant factor in career development     

Ulla Kann  Andrew Quarmby 《International journal for the advancement of counseling》1986,9(2):175-188

The purpose of this paper is to describe the role of the Botswana study-service scheme (Tirelo Setshaba) in the career development of its participants. Study-service is defined as community service used to educate those who participate in contrast to other service programmes where the main objective is to provide manpower e.g. by providing service to the community. First, the existing career development situation in Botswana for senior secondary school students is reviewed and findings from some recent research in this field in the country are presented. Second, the nature of the one year experience gained by Tirelo Setshaba participants is described including the uniqueness of Tirelo Setshaba as compared to other similar schemes in that service takes place before post-secondary education, but with other policies being similar to those developed for university students. Third, the paper presents a rationale for career development assistance for Tirelo Setshaba participants and describes career development material prepared for them. The nature of the scheme, with two or a maximum of four participants assigned to a village, has made it necessary to design a career service for clients who are so widely scattered that the often-used career talks, conventions or one-to-one counselling are impractical. Finally, the paper argues for a proper evaluation of Tirelo Setshaba's impact on career development as the conclusions drawn in the paper are based on limited observations.Senior Research Fellow, National Institute of Development Research and Documentation, University of Botswana. She has served for several years as planning officer with the Ministry of Education in Botswana and as a psychologist (career guidance) in Sweden.Tirelo Setshaba Adviser, Ministry of State President, Botswana.
