The development of students' interest in school science activities, their understanding of central chemical concepts, and the interplay between both constructs across Grades 5–11 were analyzed in a cross-sectional paper-and-pencil study (N = 2,510, mean age 11–17 years). Previous empirical findings indicate that students' knowledge increases over the time of secondary school while students' interest, especially in natural science subjects, tends to decrease. Concomitantly, there is evidence for an increase in the positive coupling between interest and knowledge across time. However, previous studies mainly rely on rather global measures, for example, school grades or general subject-related interest, and focus on science as an integrated subject instead of specific disciplines, for example, chemistry. For this article, more proximal and differentiated measures for students' understanding of three chemical concepts (Chemical Reaction, Energy, Matter) and interest in seven dimensions of school science activities according to the RIASEC + N model (Realistic, Investigative, Artistic, Social, Enterprising, Conventional, and Networking; cf. Dierks, Höffler, & Parchmann, 2014) were applied. The results are in line with previous research indicating a general increase in conceptual understanding and a decline in students' interest for all school science activities. However, the interplay between conceptual understanding and interest differs across the seven dimensions. Interest in activities which are likely to promote cognitive activation (investigative, networking) or involving the communication of knowledge (social, enterprising, and networking) are increasingly connected to conceptual understanding, especially in upper secondary grades. Interest in guided hands-on activities (realistic) which are typical in secondary science teaching, however, shows only small positive correlations to students' conceptual understanding across all grades. Hence, in upper-secondary school, investigative, social, enterprising, and networking activities seem to provide opportunities to benefit most from the interrelation between students' interests and their understanding. 相似文献

Research Findings: Preventing challenging behavior in young children is a national priority. The number of young children with behavioral problems is on the rise. Discipline policies can help early childhood programs build an infrastructure that promotes social and academic success. This study sought to document the extent to which existing early childhood program discipline policies implement the essential features for developing high-quality, system-wide (viz., program- and school-wide) discipline policies. Using the Early Childhood Discipline Policy Essentials Checklist, investigators assessed the quality of 65 discipline policies from state-licensed early childhood care and education programs. Practice or Policy: Results revealed that early childhood program discipline policies, for the most part, fail to sufficiently address those essential features known to contribute to reducing challenging behavior and promoting prosocial behavior in young children. 相似文献

To meet the rapid evolution of visual media and changing patron expectations, Brigham Young University's Harold B. Lee Library created Byugle, a device to stream videos to their users. This article describes the new challenges streaming video creates for librarians and the cooperative efforts of subject librarians, technical services, and the Information Technology Department as they work together to meet these challenges to provide streaming media for their patrons. 相似文献

A seismic retrofitting project required the UCSB Library (University of California, Santa Barbara) to permanently reduce its on-site collections by 120,000 volumes. To accomplish this successfully, a strong collaboration with the faculty was essential. This article describes a planning process in which the library worked with a faculty committee to implement a campus-wide survey of faculty and graduate students regarding their behaviors and preferences in accessing and using the collections. The survey outcomes informed a common understanding of which physical materials should remain on-site and which could be moved to storage with the least impact on research and teaching. 相似文献

In this article, we address the relatively unsubstantiated claim that there is an important relationship between organizational culture and the ability to successfully implement Quality Management (QM) programs in schools. This relationship has not been adequately explored in the literature due to the lack of a comprehensive framework for defining and measuring the values and beliefs at the root of specific types of organizational cultures. After presenting some background on organizational culture used in research to date, we outline the specific values and beliefs underlying QM practice in schools. These QM values and the accompanying propositions provide an important step toward future empirical research aimed at understanding the relationship between organizational culture, the implementation of systemic improvement initiatives like QM, and key organizational and individual outcomes. The context of our research is U.S. high schools, but the general principles could be applied to other educational settings as well. The results of our review suggest that some of the quality management culture dimensions are highly consistent with educational research on school improvement, while others are more controversial. 相似文献

In this study, the pedagogies of the home used by Latinos as they attend schools in the USA are highlighted. We hope to use the stories of Arturo and Ruben, successful Latinos, as a means to show that Latinos are developing strategies that can be shared through the telling of their stories and to claim the value of voicing the difficult realities of Latinos as they resist falling victim to anticipated self-fulfilling prophecies and move creatively through the educational pipeline to reach their best defined possible selves. 相似文献

An analysis of 19 care-provider interviews demonstrates four different orientations toward spirituality: exclusive spirituality, inclusive spirituality, conflicted spirituality, and spirituality as separate from care. Two prominent ethical dilemmas experienced by care providers are discussed. Care providers face an internal dilemma presented by competing discourses that suggest different ways to incorporate spirituality into care. Care providers also face an interactional dilemma as they seek to balance their own spiritual needs with the needs of care recipients. 相似文献

The purpose of this study was to examine the accuracy of the SW-701 (Yamax Corporation, Tokyo, Japan) and NL-800 (New-Lifestyles, Inc., Lee's Summit, Missouri, USA) pedometer in fifth-grade students while walking, skipping, galloping, sliding, and hopping. Counts registered by both pedometer models were significantly lower than actual counts while skipping, galloping, and sliding, and counts from the NL-800 were significantly lower than the SW-701 during these same movements. No significant differences in step counts were detected between actual counts and the SW-701 and between the pedometer models while walking and hopping; however, the NL-800 registered counts significantly higher than actual counts while hopping. Bland–Altman plots suggest the greatest variability occurred while skipping, galloping, and sliding, with the percent error lowest in the SW-701 during these movements. 相似文献
