Access to scholarly information in the disciplines of education and medicine occurred primarily through the simultaneous development of two bibliographic databases. The Education Resource Information Center (ERIC) originated as a resource designed to be comprehensive in its inclusion of peer-reviewed and unpublished literature for the entire education community. MEDLINE began as a resource of selective materials for physicians and researchers. Today, ERIC includes selected peer-reviewed literature directed primarily to researchers and practitioners, although others use the database, while MEDLINE is a vast information system serving all health professionals and consumers. This literature analysis of their policy history shows important differences in their evolution. Application of the Multiple Streams Framework can help in formulating possible explanations for the different developmental paths. These paths include: the degree of centralization or decentralization of the information system's organizational structure; the stability of the organizational mission; and the success of assessment strategies, federal budgetary support, and bias toward science in federal policy-making. These two government-supported databases served as models for a plethora of other databases. However, one was successful in acquiring funding from the outset, while the other continually suffered deficiencies in support. The importance of each to public welfare should have been obvious, but was not.  相似文献

Technology education students: e-tutors for school children   总被引:1,自引:0,他引:1  
E-tutoring refers to individualised learning support mediated by Internet technology. While increased demand for tutors has led to a surge in commercial e-tutoring services, volunteer e-tutoring programs for children are rare. To test the viability of volunteer e-tutoring for elementary school students, 10 undergraduate students enrolled in a technology education (TE) course provided online with instructional support to children in need of tutoring services. Each e-tutor was assigned a specific child, developed a Web Course Tools course and corresponding online activities to improve teacher-identified skill deficiencies, and provided 8 weeks of e-tutoring. Three video conferences complemented online instructional interaction between e-tutor and e-tutee. Children, parents and TE students expressed positive evaluation of the initiative.  相似文献

Research fairly consistently demonstrates that teachers are an important measurable factor in student learning, yet few teacher characteristics are shown to be consistently related to student achievement. Using a state administrative dataset that matches individual students to their teachers over time, I find that math teachers’ undergraduate performance, as measured by GPA (overall, math, and math education) and course hours (math and math education), is predictive of 5th grade math achievement. The effects of the teacher characteristics are mediated by years of experience and vary according to student types.  相似文献

The paper discusses an on-going research project that studies students' and teachers' conceptions and dispositions of mathematics. Conceptions are the views that students hold on a subject, and what they believe is required in learning and doing the subject. Dispositions are the beliefs or tendencies to exhibit a frequent, conscious and voluntary behavior directed towards learning a subject. The participants are high school students, higher education students and mathematics teachers. The study utilizes self-reporting tools as well as focus groups and interviews in a three-stage research model. This is a work on progress. Results to date are briefly discussed.  相似文献

The impact of family background on academic achievement, educational trajectories and life chances more generally has been a point of interest among academics for many years. The issue has been researched both quantitatively and qualitatively, with the two traditions generating quite different pictures of family-level ‘variables’ and processes related to child outcomes and boarder inequalities in education. This paper presents evidence of how parenting aspirations, strategies and practices vary according to social class gradients and work together in a holistic way to (re)produce social advantage and disadvantage during the primary school years.  相似文献

Increasingly, humans are an urban species prone to ‘plant blindness’. This demographic shift and situation has implications for both individual and collective perceptions of nature, as well as for addressing ‘ecophobia’ and encouraging ‘biophilia’ through education. Contemporary humanity occupies a world in which extensive physical change, both in the landscape and its related organisms, is occurring . Education-related debates on these issues links to the noted phenomenon of a ‘bubble wrap generation’ growing up within ‘nature-deficit’ childhoods in ‘megalopolitan cities’. Indeed, some commentators consider that 'nature has already disappeared' and exists only in protected spaces. Such perceptions have consequences for education in ‘presented world’ settings such as zoos, botanic gardens and natural history museums. This editorial, and its associated collection of papers, considers the critical relationships between nature, culture and education in contemporary botanic gardens and the ways in which visitors navigate their journeys, as demonstrated by research.  相似文献

Abstract

The purpose of this study was to establish the characteristics of the movement patterns common to flutter kicking of skilled swimmers and to determine how the movement patterns of swimmers at different levels of a “learn-to-swim” programme differ from those of skilled swimmers. Also, the nature of the skill afforded the opportunity to investigate learning of a cyclical multi-joint task from a motor control perspective. The underwater motion of nine children representing three levels of a “learn-to-swim” programme and 10 skilled swimmers were video-recorded while performing nine cycles of prone flutter kicking. Kinematics including joint angular motion and coordination of joint actions were calculated. Fourier analysis was applied to determine the frequency composition of the vertical undulations of the hip, knee, and ankle and to calculate the velocity of the body wave travelling caudally from hip to ankle. Fourier analysis also enabled investigation of biological noise, as distinct from variability. The results indicated the desired joint angles and coordination towards which learners could be guided. An index based on the ratio of hip – knee and knee – ankle body wave velocities showed that the inter-joint coordination of most learners was not appropriate for effective flutter kicking. There was strong evidence to suggest that skilled performance in flutter kicking is characterized by sequencing of joint actions to produce a single sinusoidal body wave moving caudally with not decreasing and preferably increasing velocity, low biological noise, and small variability.  相似文献

Abstract

Previous research indicates that young athletes as well as athletic administrators hold gender-role stereotypical beliefs about coaches that disfavor females. The validity of two such beliefs (lack of qualified female coaches and time constraints due to family responsibilities) was examined in a statewide survey of 256 female and 296 male interscholastic coaches and a nationwide survey of 2,719 male and 1,449 female interscholastic coaches. Statistical analyses (p < .001) indicated that female coaches were (a) more qualified than their male counterparts with respect to coaching experience with female teams, professional training, and professional experience; (b) as qualified as male coaches with regard to intercollegiate playing experience; and (c) less qualified than male coaches with respect to high school playing experience and coaching experience with male teams. Findings also indicated that male rather than female coaches more often experienced time constraints due to family responsibilities.  相似文献
