AbstractThis study focuses on the uses that two groups of higher education students make of technological resources offered by an institution to build their own personal learning environments. The main thesis is that these uses depend on the techno-pedagogical design of the teaching and learning process in which the technological resources are framed. In order to explore and illustrate this thesis two instructional sequences have been analysed. Both use the same technological design, the Elgg platform, which allows users to select and organize a set of resources or widgets according to their interests and needs. The results show that in both cases the uses that students make of technology are related to the characteristics and requirements of the particular techno-pedagogical designs. We conclude that the key is not to offer technological resources to the students so they can build their own personal learning environments, but to design activities that attract and induce them to build these personal environments and to guide and support the process of construction. 相似文献

From the beginning of the 1990s, different types of quality management and evaluation systems have become integrated into higher education institutes throughout Europe due to the creation of the European Higher Education Area (EHEA). This has meant that the university libraries have had to learn how to evaluate their services and improve their quality. Quality audits are one tool that can be used in quality management approaches to assess how well an organization is being managed. This paper describes and benchmarks the use of external and internal auditing in three European academic libraries, i.e. the Medical Library of the University Medical Center Hamburg-Eppendorf (Germany), the Universitat Autònoma de Barcelona Library (Spain) and the University of Eastern Finland Library (Finland). The results reveal the best practices of auditing in these institutions; and recommendations are provided for the further development of library auditing and ways to improve co-operation between libraries. 相似文献

In the light of the modern idea of a sovereign and self-transparent subject, the paper evaluates the philosophical and ethical relevance of Bildung . As a first step, (the early) Nietzsche's and Adorno's criticism of Bildung is explicated, a criticism based upon the thinkers' critical stance towards the modern epistemological relation of subject and object. However, neither thinker abandons the concept of Bildung . The second part of the paper accordingly reconstructs Nietzsche's and Adorno's adherence to Bildung understood as a different relationship of subject and object within Bildung . In the paper's concluding reflections there is an attempt to assess the systematic educational consequences, and to shed light on the ethical relevance, of a non-transparent subject of Bildung. 相似文献

The Competitive State Anxiety Inventory-2 (CSAI-2) is one of the most frequently used instruments when assessing competitive state anxiety in sport psychology research. However, doubts have been expressed about the factorial validity of both the English and the Greek versions of the scale. Hence, a revised version of the inventory (CSAI-2R) has recently been suggested to be more psychometrically sound (Cox et al., 2003). In the present study, the aim was to evaluate the psychometric properties of the Swedish version of the CSAI-2 using confirmatory factor analyses. A total of 969 athletes (571 men and 398 women) competing in 26 different sports completed the Swedish version of the CSAI-2. Three different factor structures were evaluated: the original three-factor model (with cognitive anxiety, somatic anxiety and self-confidence), a two-factor model in which self-confidence was excluded, and a three-factor model containing 17 items (CSAI-2R). The results revealed that only the 17-item model displayed an acceptable fit to the data. Although some doubts remain about the amount of variance that can be attributed to error variance in the subscales, the results suggest that it is better to use the CSAI-2R rather than the original CSAI-2. 相似文献

We have developed a method for studying cellular adhesion by using a custom-designed microfluidic device with parallel non-connected tapered channels. The design enables investigation of cellular responses to a large range of shear stress (ratio of 25) with a single input flow-rate. For each shear stress, a large number of cells are analyzed (500–1500 cells), providing statistically relevant data within a single experiment. Besides adhesion strength measurements, the microsystem presented in this paper enables in-depth analysis of cell detachment kinetics by real-time videomicroscopy. It offers the possibility to analyze adhesion-associated processes, such as migration or cell shape change, within the same experiment. To show the versatility of our device, we examined quantitatively cell adhesion by analyzing kinetics, adhesive strength and migration behaviour or cell shape modifications of the unicellular model cell organism Dictyostelium discoideum at 21 °C and of the human breast cancer cell line MDA-MB-231 at 37 °C. For both cell types, we found that the threshold stresses, which are necessary to detach the cells, follow lognormal distributions, and that the detachment process follows first order kinetics. In addition, for particular conditions’ cells are found to exhibit similar adhesion threshold stresses, but very different detachment kinetics, revealing the importance of dynamics analysis to fully describe cell adhesion. With its rapid implementation and potential for parallel sample processing, such microsystem offers a highly controllable platform for exploring cell adhesion characteristics in a large set of environmental conditions and cell types, and could have wide applications across cell biology, tissue engineering, and cell screening. 相似文献
