The demand for greater public accountability is changing the nature of ex ante peer review at public science agencies worldwide. Based on a four year research project, this essay examines these changes
through an analysis of the process of grant proposal review at two US public science agencies, the National Institutes of
Health (NIH) and the National Science Foundation (NSF). Weaving historical and conceptual narratives with analytical accounts,
we describe the ways in which these two agencies struggle with the question of incorporating considerations of societal impact
into the process of peer review. We use this comparative analysis to draw two main conclusions. First, evaluation of broader
societal impacts is not different in kind from evaluation of intellectual merit. Second, the scientific community may actually
bolster its autonomy by taking a broader range of considerations into its peer review processes. 相似文献

Seventy‐seven new academics – 59 at a large, public university in the UK and 18 at a medium‐sized, private comprehensive university in the USA – were asked to read an extract of an article on the scholarship of teaching and learning (SoTL) and mark the text according to categories of difficulty or dislike. Analysis of the data revealed six main linguistic barriers in the text: specialist vocabulary, passive constructions, pronouns, figurative language, derivations and poor editorial standards. These barriers were similar at both institutions, suggesting they apply across different contexts. Contrary to expectations, no conclusive disciplinary‐based distinctions were detected. Implications for both readers and writers are explored and proposals are made for developing a literary style in SoTL literature that is simultaneously accessible and credible. Soixante‐dix‐sept nouveaux enseignants – cinquante‐neuf provenant d’une université publique britannique de grande taille et dix‐huit provenant d’une université privée américaine de taille moyenne – ont lu l’extrait d’un article portant sur le scholarship of teaching and learning (SoTL) et ont identifié les parties qu’ils jugeaient difficiles ou qu’ils n’appréciaient pas. Une analyse des données révèle la présence de six barrières linguistiques principales dans le texte: le vocabulaire spécialisé, les constructions passives, les pronoms, le langage figuratif, les dérivations et des standards de rédaction de piètre qualité. Ces barrières étaient similaires dans le cas des deux institutions, ce qui suggère qu’elles sont applicables dans des contextes différents. Contrairement aux attentes, aucune distinction reposant sur les disciplines permettant de tirer des conclusions n’a pu être détectée. Les implications pour les lecteurs et les rédacteurs sont explorées et des propositions visant à développer un style littéraire pour la documentation portant sur le SoTL qui soit à la fois accessible et crédible sont formulées. 相似文献

Inclusive education has been introduced through a number of policy developments in Malaysia over the last 10 years but there is little research investigating the extent and nature of inclusive education for preschoolers with special educational needs (SEN). This study surveyed both regular and special education teachers in Malaysian integrated preschools asking them about the level and nature of inclusion taking place in their preschools and their perceptions and beliefs about inclusion. There was little evidence of practices of inclusion taking place. Both regular and special educators agreed that SEN should be educated alongside their peers in a school but were unlikely to agree that the SEN students should be in the same classroom. Factors identified as influencing inclusion included school culture, skills and competency, guidance and information, workload and students' disabilities. More guidelines and support are required for successful inclusion in Malaysian integrated preschools. 相似文献

When General Certificates of Secondary Education (GCSEs) were introduced in the late 1980s, coursework was included as a requirement in many subjects. Coursework was intended to help best represent students' attainments, but concerns about various issues (e.g., tasks becoming formulaic, authenticity of student work, workload) led to a review and ultimately to its replacement with “controlled assessments”. This research investigated the effects of this change. A questionnaire was completed by 346 teachers across 6 subjects. Most teachers felt the risks of plagiarism are similar or have reduced. Two thirds of teachers reported that the introduction of controlled assessment has affected the way they teach, and around 60% feel it has affected the nature of the knowledge and skills learnt by students. There are reportedly practical challenges relating to timetabling, student absence, and increased administration. However, over 70% of teachers consider it “important” or “very important” to have some form of internal assessment in their subject. 相似文献

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010, 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time. 相似文献

Community colleges have become increasingly reliant on diversifying their revenue sources, and turning to private fund raising has become a common strategy for many of them. Although fund raising has been a common practice in higher education since its inception, it has only emerged in the two-year college sector in the past several decades. The current study sought to identify donors at a case study, suburban community college, specifically exploring giving patterns over time and testing the conceptual framework of a pyramid of giving that overlays institutional involvement and commitment with giving levels. Major infrastructure inconsistencies prevented much of the framework testing, but data were capable of creating an initial donor and giving profile for a typical community college. This profile demonstrated that board members and employees were the most loyal and consistent in making contributions, but that these gifts often were stable over time and did not increase to become major gifts. Also, private business and industry gifts were often given at the same level as individual gifts, perhaps illustrating the responsiveness and cooperation between community colleges and the local workforce. 相似文献

Two Lagrange multiplier (LM) methods may be used in specification searches for adding parameters to models: one based on univariate LM tests and respecification of the model (LM‐respecified method) and the other based on a partitioning of multivariate LM tests (LM‐incremental method). These methods may result in extraneous parameters being included in models due to either sampling error or the model being misspecified. A 2‐stage specification search may be used to reduce errors due to misspecification. In the 1st stage, parameters are added to models based on LM tests to maximize fit. Second, parameters added in the 1st stage are deleted if they are no longer necessary to maintain model fit. Illustrations are presented to demonstrate that errors due to misspecification occur with the LM‐respecified method and are even more likely with the LM‐incremental approach. These illustrations also show how the deletion stage can help eliminate some of these errors. 相似文献

This essay explores the relations between T. S. Eliot's concept of tradition and the ‘modern materialism’ of Walter Benjamin, Jacques Lacan and Louis Althusser, and considers the implications of this resonance for both Eliot's critical legacy and the Marxist tradition. Initially surveying the critical controversy surrounding the canonical figure of Eliot and recent attempts to reconcile his avant-garde poetics with his reactionary social thought, the essay traces the roots of Eliot's tradition in a Nietzschean critique of historicism and its development into a theory of culture. Eliot's persistent drive towards impersonality echoes (and problematises) the efforts of Benjamin, Lacan and Althusser to construct a model of the social process that incorporates the unconscious. Rather than ultimately determining a set of political positions, the ‘missed encounter’ between Eliot's tradition and ‘modern materialism’ draws to light the Hegelian historicisms that haunt materialist theories of culture. 相似文献
