Many previous time allocation studies treat work as a single activity and examine trade-offs between work and other activities. This paper investigates the at-work allocation of time among teaching, research, grant writing and service by science and engineering faculty at top US research universities. We focus on the relationship between tenure (and promotion) and time allocation, and we find that tenure and promotion do affect the allocation of time. The specific trade-offs are related to particular career paths. For example, full professors spend increasing time on service at the expense of teaching and research while longer-term associate professors who have not been promoted to full professor spend significantly more time teaching at the expense of research time. Finally, our results suggest that women, on average, allocate more hours to university service and less time to research than do men. 相似文献
In its 50 years of existence, the United Nations Economic Commission of Africa (UNECA) has created and holds a vast quantity of information and knowledge in a variety of formats, including printed and electronic. These represent the corporate memory, providing historical evidence of its actions and decisions. The information resources include published materials such as flagship publications, journal articles, conference proceedings, technical reports, mission reports, annual reports, working papers, policy briefs, speeches and other grey literature, all which outline important research or decisions that have been made on the economic and social development in Africa. In 2009 the Library was awarded seed funding to implement the ECA Institutional Repository (IR). This paper discusses the various activities that have been undertaken to realize the project including; highly customized Dspace installation to support the MARC21 metadata, digitization, migration of metadata from the Library Integrated Management System (HORIZON) and, customization of the Dspace workflow to enable review of imported records. The paper also highlights lessons learnt, challenges and some of the best practices developed throughout the implementation and roll out of the ECA IR project. The Institutional Repository at http://repository.uneca.org/ is the first of its kind within the United Nations Secretariat and offers unique knowledge and information not available elsewhere pertaining to regional programmes, decisions and resolutions promoting social and economic development of Africa. 相似文献

In this report, we adapt and extend a methodology for documenting the collective production of meaning in a classroom community.
A cornerstone of the methodological approach that we develop is a close examination of classroom discourse. Our efforts to
analyze the collective production of meaning by examining classroom interaction are compatible with the relatively recent
emphasis in mathematics and science education research that focuses on how communities of learners establish ideas through
discourse and inquiry. The methodological approach we take builds on and extends an approach from mathematics education that
uses Toulmin’s argumentation model to document and analyze students’ conceptual progress. Our modification introduces a new
criterion for empirically demonstrating when particular ways of reasoning become part of the normative practices of the community.
An example from an undergraduate course in physical chemistry is used to illustrate the methodology. 相似文献
A long‐term, 2 year in‐service provision to develop pupils thinking capability was provided for 91 secondary schools during the period 1998–2002. The science teachers involved reported that the in‐service experience impacted on their pedagogic practice. The evidence was gathered through reflective surveys and interviews. The in‐service programme engaged the teachers in authentic learning activities. The findings suggest that engaging the teachers in actions or processes which are then transformed into conceptual (scientific and cognitive) objectives can influence their perception of learning. Through collective reflection of their active participation they objectified connections between learning processes and learning outcomes. The explicit reflections of the modelled experiences provided the opportunity for the teachers to empathize, as learners, with their pupils' learning situations. They were guided to reflect on how the nature of social interactions can impact on reasoning and meaning making. The reflective cognitive and learning objectivity of the in‐service programme appeared to influence their pedagogy in a variety of ways. The pedagogic changes included a significant increase in pragmatic interpretation and application of learning theories to classroom situations. Teaching strategies were also developed to include: proactive management of collaborative learning; a generally more interactive and dynamic way of learning through questioning; promotion of more prediction opportunities; encouragement of more reflection, in a variety of ways, on the processes by which potential or actual solutions to scientific tasks or challenges were reasoned. As a result of this study pedagogic principles to support learning and cognitive development in science and learning generally are proposed.
Une expérience continue à long terme sur une période de deux ans pour développer la capacité de réfléchir chez les élèves a été offerte à 91 collèges et lycées pendant la période entre 1998 et 2002. Les professeurs de sciences qui y étaient engagés ont déclaré que l'expérience continue a influé sur leur pratique pédagogique. Les preuves ont été réunies grâce aux enquêtes et aux interviews. L'expérience a engagé les professeurs dans des activités d'apprentissage authentiques. Les conclusions semblent indiquer qu'en engageant les professeurs dans des actions ou des procédés qu'on transforme ensuite en objectifs conceptuels (scientifiques et cognitifs) on peut influer sur leur perception de l'apprentissage. En réfléchissant collectivement à leur participation active, ils s'étaient engagés dans l'activité collective de faire de ce qu'on faisait auparavant l'objet de réflexion. Par suite de ces réflexions, les professeurs, en tant qu' apprenants, ont pu comprendre ce que ressentent leurs élèves dans les situations d'apprentissage. Ils ont été guidés à considérer l'effet des relations sociales sur le raisonnement et la compréhension. Il paraît que l'objectivité d'apprentissage cognitive et réflective a influé sur leur pédagogie à bien des égards. En ce qui concerne les changements pédagogiques, il y a eu une augmention significative de l'interprétation pragmatique et de l'application des théories d'apprentissage dans la salle de classe. Des stratégies pédagogiques ont également été développées qui comprennent une direction d'apprentissage qui fait preuve d'initiative; une façon d'apprendre en posant des questions qui est généralement plus interactive et dynamique; la promotion de plus de possibilitiés de prévision et l'encouragement à réfléchir plus à bien des égards sur les procédés qu'on utilise pour arriver aux solutions potentielles ou réelles des tâches et des défis scientifiques. L'impact de ces développements pédagogiques dans la salle de classe a été étudié mais on le présente ailleurs. Par suite de cette étude on propose des principes pédagogiques pour soutenir chez les élèves le développement cognitif et l'apprentissage des sciences et l'apprentissage en général.
Un estudio a largo plazo de dos años se llevó a cabo en 91 escuelas secundarias durante el periodo de 1998–2002, para desarrollar las capacidades de pensamiento de los alumnos. Los profesores de ciencia que participaron en el estudio informaron que la experiencia tuvo impacto en sus prácticas pedagógicas. La evidencia se obtuvo a través sondeos y entrevistas de reflexión. El estudio involucró a los profesores en experiencias auténticas de enseñanza. Los hallazgos sugieren que involucrar a los profesores en acciones o procesos los cuales luego son transformados en objetivos cognoscitivos (científicos o conceptuales), puede influenciar su percepción a cerca del aprendizaje. Las reflexiones explícitas de las experiencias modeladas proveyeron la oportunidad a los profesores de tener empatía, como estudiantes, con las situaciones de aprendizaje de sus alumnos. Ellos fueron guiados a reflexionar a cerca de cómo la naturaleza de las interacciones sociales puede tener impacto en el razonamiento y en el proceso de crear significado. La reflexión cognoscitiva y la objetividad del aprendizaje por parte de los profesores participante pareció influenciar sus métodos pedagógicos de varias formas. Los cambios pedagógicos incluyeron un aumento significativo en la interpretación pragmática y la aplicación de las teorías de enseñanza en las situaciones en la sala de clases. También se desarrollaron estrategias de enseñanza para la administración activa del aprendizaje en colaboración; una forma de aprendizaje a través de hacer preguntas que es generalmente más interactiva y dinámica; el promover más oportunidades para hacer predicciones y estimular más reflexión, de varias maneras, en los procesos por los cuales se razonan las soluciones actuales o potenciales para las tareas o retos científicos. Se estudió el impacto de estos desarrollos pedagógicos en el aprendizaje de los alumnos, pero son mencionados en otra parte. Como resultado de este estudio se proponen principios pedagógicos que apoyan la enseñanza y el desarrollo cognoscitivo en las ciencias y la enseñanza en general.
Zwischen 1998 und 2002 wurde an 91 amerikanischen Mittelstufenschulen ein zweijähriges Projekt durchgeführt, das dazu diente, die Fähigkeit zu selbständigem, wissenschaftlichem Denken der Schüler zu entwickeln und zu fördern. Die beteiligten Lehrer in den wissenschaftlichen Fächern berichteten, dass dieses Experiment ihre pädagogische Praxis beeinflusst hat. Dieses Ergebnis beruht auf der Auswertung von Fragebögen und Einzelgesprächen. Durch das Projekt wurden die Lehrer mit authentischen Lernprozessen konfrontiert. Die Ergebnisse deuten darauf hin, dass die Einbeziehung der Lehrer in Prozesse, die anschließend in konzeptionelle (wissenschaftliche und kognitive) Zielsetzungen umgewandelt werden konnten, ihre Vorstellung vom Lernprozess ändern kann. Durch die expliziten Reflektionen über die gewonnene Erfahrung wurde es den Lehrern ermöglicht, sich als Lernende mit den Lernsituationen ihrer Schüler zu identifizieren. Sie wurden angeregt, darüber nachzudenken, wie die Art sozialen Umgangs Einfluss auf Argumentation und Meinungsbildung haben kann. Die reflektive kognitive Objektivität des Experiments scheint die Pädagogik auf mehrere Arten zu beeinflussen. Pädagogische Änderungen erstreckten sich u.a. auf eine signifikante Zunahme der pragmatischen Interpretation und Anwendung von Lerntheorien auf Situationen im Klassenzimmer. Darüber hinaus wurden Lernstrategien entwickelt, um proaktives Management kollektiven Lernens, eine generell interaktivere und dynamischere Art des Lernens durch gezielte Fragen, eine Förderung von Vorhersagemöglichkeiten und Ermutigung zu mehr Reflektion auf verschiedene Arten einzuschließen. Die Auswirkungen dieser pädagogischen Entwicklungen auf das Lernverhalten von Schülern wurden untersucht und in einer separaten Studie veröffentlicht. Aufgrund dieser Studie werden pädagogische Prinzipien zur Unterstützung kognitiver Entwicklungen in Wissenschaft und Lehre vorgeschlagen. 相似文献
This paper discusses an emerging development methodology, Performance Support Engineering, that can be used to design and build performance support systems. It introduces a new model called the Organizational Performance/Learning Cycle that describes the dynamics of the organizational learning process and provides a framework for thinking about the technologies (Ariel 1994) and methodologies that enable that process. The author argues that previous definitions of EPSS were too limited and restricted in their scope and expands on these earlier definitions to take into account this new model of organizational learning. The new dofinition clparly distinguishes EPSS from traditional systems development, which focuses on data, not on knowledge, and from expert systems development, which focuses on knowledge rather than on enabling performance. This new view of EPSS offers a clear opportunity for organizations to recognize the strategic importance of managing their knowledge assets. Most of the current methodologies in use by different functional groups are limited in their capability to enable this model and the expanded definition of EPSS. The author describes how the emerging Performance Support Engineering methodology overcomes those limitations. 相似文献
This article considers the determinants of student access of a specific course Web site from a Principles of Macroeconomics course. As they prepare for the course's in-class exams, students may choose either or both of two Web resource types, a dynamic resource (interactive multiple choice practice exams) or various static resources. The article addresses two related questions. First, we ask whether a given set of characteristics affects the access of these different Web site resources similarly. Second, we explore the influence of certain student characteristics on the student decision to access a given Web resource. In general terms, our findings suggest results that are consistent with existing studies of how students learn. Our results also suggest that a greater diversity of resources will, in fact, elicit wider use of one's course Web site. 相似文献
