Abstract Most language instructors use resources found on the Internet to supplement their courses (Adolph and LeBlanc, 1997). This article shows how a teacher can make use of templates to create their own Internet pages. 相似文献

Regulation of clinical practice is a characteristic aspect of the medical profession. Regardless of whether this regulation derives from government-sourced guidelines or materials from government-sponsored institutions, it results in a high production of information resources (institutional information resources), which are disseminated to the clinical stuff in order to ensure compliance. In that case, the issue of credibility of these information resources might arise, since medical practice is characterized by a high frequency of change. The latter involves a continuous effort on the part of the clinical staff, which is motivated by work-related factors (e.g., need for compliance) or personal motivation (e.g., need for self-improvement). In this study we consider a simple trust model, according to which we assume that perceived trust is a direct antecedent of perceived credibility. We evaluate whether work-related or personal motivating factors influence the relation between perceived credibility and trust toward institutional information sources and how the effect of each factor affects this relation. Findings suggest that work-related factors have a higher impact on the relation between credibility and trust than personal motivation factors, while they are stressing the important role of hospital libraries as a dissemination point for government-sponsored information resources. 相似文献

Eight rhesus monkeys were trained on a counterbalanced series of concurrent, two-choice, discrimination tasks that provided different numbers of correct or incorrect objects as lists of discriminanda. Small, large, or infinite lengths of correct or incorrect object lists were combined in different tasks, and acquisition performances were compared. When tasks had an infinite number of objects in their correct list and a small number (4) in their incorrect list, acquisition entailed significantly less error than was seen when a small number of correct objects was paired with an infinite incorrect list. This pattern of outcomes seemed attributable to novelty preference. However, comparison of error distributions from tasks with infinite. list lengths to distributions from analogous tasks with fixed list lengths provided some basis for interpreting the way monkeys integrated information that emerged from the temporally discriminative properties of the tasks. One prospective concern was whether or not these performances represented behaviors like those seen in human cognitive discriminations of frequency of occurrence. 相似文献

The Role of Metacognitive Activities in the Contextual Use of Primary Pupils' Conceptions of Science
Petros Georghiades 《Research in Science Education》2006,36(1-2):29-49
This paper addresses the problematic nature of pupils' attempts to use their science conceptions in contexts other than the
ones in which the original learning of the concept takes place. It reports research with 60 Year-5 primary school children
studying current electricity, during which the researcher employed metacognitive activities alongside normal teaching procedures,
in an attempt to enhance cross-contextual use of taught concepts. In order to assess the effect of different contexts on pupils'
performance, a test was repeatedly administered over one school year that tested the same concepts in distinctly different
contexts. Although the role of a familiar context is only partly determined, the results suggest that pupils' ability to use
concepts in unfamiliar contexts is stable for a long period of time. The results also support the provision of metacognitive
activities as a means of enhancing pupils' ability for cross-contextual use of their conceptions of science. 相似文献

Research and development (R&D) investment activity plays a crucial role in developing high-tech industries. In recent decades, China has made sustained investments in its domestic high-tech industries, with the goal of increasing their productivity. This paper investigates the effect of this investment on relative R&D efficiency across China's high-tech sectors. Data Envelopment Analysis (DEA) was used to generate quantitative indices for sector comparisons. The analysis of this study indicates that overall R&D investment efficiency did not increase from 1998 to 2009, despite R&D expenditure increasing by 2188%. Over the same period, most sectors suffered from decreasing returns to scale (DRS), presumably also reflecting the inefficient R&D investment. Most of the sectors showed significant fluctuation on R&D investment efficiency. This research result indicates that the problem of China's high-tech industry may be from the inefficiency of its technology commercialization processes, and therefore represents a critical parameter for policy makers and managers. 相似文献

This article examines whether European Commission (EC) competition policy and merger control provisions can prevent excessive market power and safeguard open access and consumer choice in the European media and communications industry. The study looks at the structure of the media industry and points to the amalgamation of corporate power. It assesses whether EC competition law and merger provisions can effectively address the dangers of ownership concentration and safeguard diversity of sources. A number of merger cases either blocked or allowed by the EC are reviewed to establish the level of competition. The article suggests that a more rigorous competition policy is required to guarantee competition and prevent domination in merger activity. 相似文献

Abstracts English: This study examined the effectiveness and efficiency of a three‐dimensional virtual reality simulation model designed to train kindergarten teachers in the understanding of kindergarten children's needs and perceptions. Statistical analysis of the data indicates that the kindergarten teachers who were trained through the virtual reality technology were significantly more understanding of children's needs and perceptions than those trained through the workshop method. Thus, in light of the results of the study, it is suggested that teacher trainers should favourably consider using virtual reality simulation models in the training of kindergarten teachers in order to maximize the effectiveness of the teacher‐training process. 相似文献

This study aimed to design a teaching sequence for science education that enabled lower secondary school students to enhance their motivation towards science. Further, it looked to examine the way the designed teaching sequence affected students with different motivational profiles. Industry site visits, with embodied theory-based motivational features were included as part of the designed teaching sequence. The sequence was implemented in Finland and Greece with 54 participants, 27 from each country. Quantitative data was collected using the Evaluation of Science Inquiry Activities Questionnaire, based on the Intrinsic Motivation Inventory but did not map the expected outcomes. Interviews, however, showed that students with different motivational profiles found aspects within the module that met their psychological needs as explained by Self-Determination Theory. The results offer a perspective to adolescents’ psychological needs along with some insights into how students mediate the way they value an activity in the context of science education. 相似文献

Museums are interested in the digitizing of their collections not only for the sake of preserving the cultural heritage, but to also make the information content accessible to the wider public in a manner that is attractive. Emerging technologies, such as VR, AR and Web3D are widely used to create virtual museum exhibitions both in a museum environment through informative kiosks and on the World Wide Web. This paper surveys the field, and while it explores the various kinds of virtual museums in existence, it discusses the advantages and limitation involved with a presentation of old and new methods and of the tools used for their creation. 相似文献
