Alvin Weinberg’s classic and much debated two articles in Minerva, “Criteria for Scientific Choice” (1963) and “Criteria for Scientific Choice II – The Two Cultures” (1964), represent two of the first and most important attempts to create a meta-discourse about priority setting in science policy, and many of the points advanced remain relevant. The goal of this paper is to elaborate on the relevance of some of Weinberg’s original arguments to priority setting today. We have singled out four issues for attention: The tension between scientific and institutional choice, the assumptions behind the triad of scientific, technological and social merit, the elusive ‘externality from size’ argument for funding promoted by Weinberg, and finally the problems involved in the idea of basic science as an ‘overhead cost’ for applied science, and applied science as an ‘overhead’ on a sectoral mission. These four issues will be elaborated from a policy perspective and connected to present day challenges for science and technology policy. 相似文献

This article explores the use of an evaluation model of learning and development utilizing formative, summative, and confirmative steps, along with a framework for developing evaluation tools aligned with organizational change goals. A case study is presented in which formative, summative, and confirmative evaluations were used to assess materials and learners following implementation of a new performance management process, tools, and supporting training. A specific model for developing evaluation tools and techniques is introduced as a way to integrate the evaluation process with the specific content of a learning and development intervention, as well as link to higher‐order cultural change goals. Results of the case study suggest that evaluation tools can provide evidence of improvement and target areas for further work. Recommendations are provided for the researcher or practitioner interested in applying the same or similar models to evaluation. 相似文献

In spite of the rising tide of metrics in UK higher education, there has been scant attention paid to assessment loads, when evidence demonstrates that heavy demands lead to surface learning. Our study seeks to redress the situation by defining assessment loads and comparing them across research and teaching intensive universities. We clarify the concept of ‘assessment load’ in response to findings about high volumes of summative assessment on modular degrees. We define assessment load across whole undergraduate degrees, according to four measures: the volume of summative assessment; volume of formative assessment; proportion of examinations to coursework; number of different varieties of assessment. All four factors contribute to the weight of an assessment load, and influence students’ approaches to learning. Our research compares programme assessment data from 73 programmes in 14 UK universities, across two institutional categories. Research-intensives have higher summative assessment loads and a greater proportion of examinations; teaching-intensives have higher varieties of assessment. Formative assessment does not differ significantly across both university groups. These findings pose particular challenges for students in different parts of the sector. Our study questions the wisdom that ‘more’ is always better, proposing that lighter assessment loads may make room for ‘slow’ and deep learning. 相似文献

Abstract Parents and teachers play an important role in stimulating student motivation. The aim of this study was to examine if both parent and teacher enthusiasm could predict intrinsic motivation toward STEM activities, and if motivation would be associated with improved STEM achievement over one year in a one-year prospective examination of 288 Swedish students in their final year of a Science High School program (143 females and 145 males). Surveys of parent and teacher enthusiasm were collected at baseline, and student intrinsic motivation and GPA in STEM were assessed at baseline and at the end of the year. Baseline GPA and intrinsic motivation as well as follow-up intrinsic motivation were significantly associated with later GPA. Finally, intrinsic motivation mediated the relation between teacher and parent enthusiasm and change in GPA. Findings show the importance of parent and teacher enthusiasm for adolescent’s intrinsic motivation and achievement in STEM. 相似文献

To improve the versatility, stability and efficiency of the Newton—Raphson technique, further extensions and formalisms are generated in the constrained family of algorithms. Specifically, this paper; (i) introduces the use of piecewise continuous constraint bounds and, (ii) extends the formal rigorous base of the constrained scheme by considering such items as convergence characteristics, the existence of safety zones and self-adaptive attributes. To benchmark the enhancements, the results of several numerical experiments involving large deformation elasticity problems are presented. These illustrate the inherent stability and efficiency of the constrained incremental scheme in handling problems with varying curvature definiteness. 相似文献

This longitudinal study draws on data from a larger project and examines how students’ perceptions of their opportunities to influence their study environment may be enacted in approaches aimed at influencing their studies, and whether this changes during the course of their studies. Ten students from a 4.5‐year Master’s programme in Engineering were studied throughout their education by means of semi‐structured in‐depth interviews, which were analysed thematically. The results indicate that students’ perceptions of their study environment were enacted in three approaches aimed at influencing their study environment: (i) to adapt to the environment and to study alone; (ii) to try to change the programme, to create an individual curriculum and to interact with teachers; and (iii) to cooperate with their peers. The thematic analysis suggests that students’ perceptions of their study environment were enacted in the different approaches and that these changed along with external demands in the programme. 相似文献

Railway transitions experience differential movements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade settlement. This differential movement is especially problematic for high speed rail infrastructure as the ??bump?? at the transition is accentuated at high speeds. Identification of different factors contributing towards this differential movement, as well as development of design and maintenance strategies to mitigate the problem is imperative for the safe and economical operation of both freight and passenger rail networks. This paper presents the research framework and initial instrumentation details from an ongoing research effort at the University of Illinois at Urbana-Champaign. Three bridge approaches experiencing recurrent geometry problems were instrumented using multidepth deflectometers (MDDs) and strain gages to identify different factors contributing to the development of differential movements. 相似文献

In current literature, metaphor is treated as either an instance of implicit comparison or as a nonliteral class‐inclusion statement. I will argue that, contrary to these positions, the notions of comparison and class‐inclusion are not mutually exclusive in character but rather complementary cognitive concepts which entail one another. While initially using the semantic distinction between literal and figurative language, I will argue in the course of this article that metaphor is a matter of extraordinary rather than ordinary language and that it reflects linguistic pragmatics rather than semantics. The most prominent reasons for resorting to the extraordinary use of language may be found in education, where metaphor serves a heuristic function in the interaction between teacher and student, and in scientific activities, when researchers have at their disposal only a restricted dictionary to describe new phenomena. Executive function, flashbulb memory, and the firing of neurons are examples from cognitive psychology and neuroscience that denominate phenomena that might otherwise not have been adequately expressed. I will conclude that metaphors are both comparisons as well as class‐inclusion statements and that these tropes fulfill not only a heuristic but also an epistemic function in as much as they render comprehensible the acquisition of radically new knowledge. 相似文献

OBJECTIVE: The purpose of this article is to: (1) illustrate the application of life table methodology to child abuse and neglect report data and (2) demonstrate the use of indicators derived from the life tables for monitoring the risk of child maltreatment within a community. METHOD: Computerized records of child maltreatment reports from a large, urban county in Ohio are cumulated for 11 years and linked for each child. Life table methods are used to estimate the probability that children from birth to age 10 will be reported victims of maltreatment by age, race, and urban or suburban residence. RESULTS: Using life tables, the estimates in the county of this study are that 33.4% of African American children and 11.8% of White children will appear in substantiated or indicated child abuse or neglect report(s) by their 10th birthday. The age-specific probability of a maltreatment report is highest in the first year of life for both groups. The probability of a child being reported for a substantiated or indicated incident of maltreatment before his or her 10th birthday is more than three times higher for city dwellers than for suburbanites in the urban county studied here. CONCLUSIONS: Life table methodology is useful for creating child well-being indicators for communities. Such indicators reveal that a larger portion of the child population is affected by maltreatment reports than would be concluded from examining cross-sectional rates and can be used to identify racial or geographic disparities. 相似文献
