In this study, productivity growth in 35 Australian universities is investigated using non-parametric frontier techniques over the period 1998–2003. The five inputs included in the analysis are full-time equivalent academic and non-academic staff, non-labour expenditure and undergraduate and postgraduate student load while the six outputs are undergraduate, postgraduate and Ph.D. completions, national competitive and industry grants and publications. Using Malmquist indices, productivity growth is decomposed into technical efficiency and technological change. The results indicate that annual productivity growth averaged 3.3% across all universities, with a range from −1.8% to 13.0%, and was largely attributable to technological progress. However, separate analyses of research-only and teaching-only productivity indicate that most of this gain was attributable to improvements in research-only productivity associated with pure technical and some scale efficiency improvements. While teaching-only productivity also contributed, the largest source of gain in that instance was technological progress offset by a slight fall in technical efficiency.  相似文献

“Deep learning” represents student engagement in approaches to learning that emphasize integration, synthesis, and reflection. Because learning is a shared responsibility between students and faculty, it is important to determine whether faculty members emphasize deep approaches to learning and to assess how much students employ these approaches. This study examines the effect of discipline on student use of and faculty members’ emphasis on deep approaches to learning as well as on the relationships between deep approaches to learning and selected educational outcomes. Using data from over 80,000 seniors and 10,000 faculty members we found that deep approaches to learning were more prevalent in Biglan’s soft, pure, and life fields compared to their counterparts. The differences were largest between soft and hard fields. We also found that seniors who engage more frequently in deep learning behaviors report greater educational gains, higher grades, and greater satisfaction with college, and that the strength of these relationships is relatively consistent across disciplinary categories.  相似文献

The present study sought to investigate the effects of a multidimensional educational intervention on high school students’ motivation and engagement. The intervention incorporated: (a) multidimensional targets of motivation and engagement, (b) empirically derived intervention methodology, (c) research-based risk and protective factors, (d) established practices that nurture optimal youth development, (e) use of interpersonally skilled staff, and (f) evidence-based programming. Using a pre-/post-treatment/control group design, it was found that the self-complete intervention brought about significant shifts in motivation and engagement. Specifically, findings showed that the treatment group made positive motivation shifts on key dimensions including task management, persistence, anxiety, failure avoidance, and uncertain control. Moreover, against a large weighted external comparison group, the treatment group made positive shifts on valuing, mastery orientation, planning, task management, persistence, failure avoidance, uncertain control, and self-handicapping. Taken together, these findings attest to the potential for multidimensional educational interventions for enhancing students’ motivation and engagement.  相似文献

Abstract

The philosophy of trust is a relatively small subfield. Nonetheless, it contains within it many important insights. Our contention in this paper is that careful study of this subfield can bring with it many insights that can and should be used to reconsider a variety of arguments that have been brought forward in the literature on the philosophy of education and other areas of educational research. Our focus is largely destructive in section 2 of the paper. We object to two recent papers from the philosophy of education literature arguing that they fail to recognise important insights from the philosophical literature on trust. In section 3 we say something more positive, noting the routes forward.  相似文献

Current guidelines recommend using single-degree-of-freedom(SDOF) method for dynamic analysis of reinforced concretec (RC) structures against blast loads, which is not suitable for retrofitted members. Thus, a finite difference procedure developed in another study was used to accurately and efficiently analyze the dynamic response of fibre reinforced polymer (FRP) plated members under blast loads. It can accommodate changes in the mechanical properties of a member's cross section along its length and through its depth in each time step, making it possible to directly incorporate both strain rate effects (which will vary along the length and depth of a member) and non-uniform member loading to solve the partial differential equation of motion. The accuracy of the proposed method was validated in part using data from field blast testing. The finite difference procedure is implemented easily and enables accurate predictions of FRP-plated-member response.  相似文献

This paper explores the nature of, and justification for, copyright in academic texts in the light of recent developments in information technology, in particular the growth of electronic publication on the internet. Copyright, like other forms of property, is best thought of as a cluster of rights. A distinction is drawn within this cluster between first order `control rights' and higher order `commodity rights'. It is argued that copyright in academic texts is founded on its role as a means to allow academics to fulfil their role responsibilities. While the possession and exercise by academics of commodity rights can be thus justified in the case of mechanical print-based publication, since this helps make possible the reproduction and dissemination of academic texts, they cannot be so justified in the case of electronic publication. There are nevertheless good reasons to retain various control rights.  相似文献
