It is no longer effective to provide information literacy instruction that is thought to be “good for” college students, but rather, instruction must focus on the learning styles and preferences of the target population. This case study reports a series of hands-on/minds-on information literacy activities that dissolve student's misconception that “techno-savvy” is synonymous with information literate. Careful and thorough instruction in the mining of popular Internet search engines for authoritative information was coupled with instruction in the use of traditional library resources. It was found that the college students studied possess a high need for clarity and a low tolerance for ambiguity, and therefore any activities assigned must be thoroughly, yet succinctly, described in order to achieve success. Combining traditional information literacy instruction with novel approaches appeals to the confidence in and reliance on Internet search engines that college students exhibit, while it moves this microcosm toward a higher level of information literacy and commitment to life long learning.  相似文献

To Catch a Liar: Challenges for Research in Lie Detection Training   总被引:1,自引:0,他引:1  
Can we train people to detect deception? It is the contention of this article that communication scholars should learn how to train law enforcement professionals on how to detect high stake lies, like those faced by police, judges, customs officials, immigration officials, and so forth. It is proposed that in order to know whether we can train or should bother to train people to detect deception, each training study must meet 6 challenges: (1) relevance, (2) high stakes, (3) proper training, (4) proper testing, (5) generalizability across situations, and (6) generalizability over time. Our quantitative review of the literature suggests that training does significantly raise lie detection accuracy rates. Meta-analytic findings indicate a mean effect size of r = .20 across 20 (11 published studies) paired comparisons of lie detection training versus the control group (i.e., those without some type of training). It should be noted that the majority of the studies that attempt to train lie detectors fall short on many of the above challenges. Current research in lie detection training may actually underestimate the ability to train lie detectors due to the stimulus materials employed in most experiments.  相似文献

The purpose of this article is to enumerate a series of security steps that might be taken by those researchers or organizations that are contemplating web-based tests and performance assessments. From a security viewpoint, much of what goes on with web-based transactions is similar to other general computer activity, but the recommendations here focus on what can be done to avoid the loss, compromising, or modification of data collected by or stored through the Internet.  相似文献

The American Association for the Advancement of Science carried out a study on intellectual property and electronic journal publishing with the aim of identifying those aspects of the intellectual property regime that facilitate or constrain the effective development of electronic scientific publishing. This paper summarizes the conclusions reached, emphasizes the continuing need to maintain the legal framework offered by copyright law, but makes recommendations both for its modification and in its application to ensure that the potential benefits of electronic publishing are fully realized. The full report by AAAS is posted on the Web at www.aaas.org/spp/sfrl/projects/epub/finalrept.html  相似文献

This essay offers a bird's eye view of new directions in the economics of education. An increasing awareness of the socialization function of education, of the screening hypothesis, of the ‘incomplete’ employment contract and of labour market segmentation is leading, it is argued, to a picture of the economic value of schooling which is simply miles removed from the old-fashioned belief that education enhances cognitive knowledge and that employers pay educated people more because they know more. The new way of looking at the economic value of schooling is illustrated by the example of youth training and work experience programmes.  相似文献

Vivarium     
This contribution is an introduction to an online forum, Vivarium, at the new open¦ed web site. The site will be accessible to an audience of: educationalists, artists, producers, development agencies and funding bodies. The forum will discuss the artist as educator, the culture of art in education, and explicitly Live Art as tool for rendering social issues for exploration in the classrooms of the future. In an era of global ecologies of information, offering users data on everything from hydroponics to Derrida's text The Truth in Painting, fertile knowledge is increasingly accessed through non‐hierarchical networks. In such a terrain, a new post‐pedagogical approach to creativity appears essential if we hope to excite, channel and challenge young people. This paper charts a series of critical issues that readers are invited to develop and discuss online, but perhaps more importantly signifies potential topics that might return in a series of subsequent dialogues commissioned by the Arts Council England for Vivarium. The broader aim of Vivarium is to create a context to frame potential initiatives that might be delivered through Creative Partnerships, the unprecedented Arts Council England initiative, promoting cultural and creative activity for young people.  相似文献

The intent of this project was to explore the feasibility of personalising the paddle blade size for individual flatwater kayakers based on their power output profiles. Twelve elite male kayakers performed on a kayak ergometer at the same intensity and resistance that they would normally experience while paddling at race pace for 500 m on the water. The kayak ergometer was instrumented so that power profiles could be determined from the instantaneous force and velocity of the representative centre point of the paddle blade. From the power profile information, the researchers calculated a personalised blade size that was expected to improve performance for those kayakers differing more than 5% from the calculated ‘ideal’ size. For the elite kayakers studied, it was recommended that seven of the paddlers should increase their blade size by approximately 5–10%. For the remaining five paddlers, the results indicated that their current blade sizes were within the expected measurement error of their predicted ideal value and should be retained. It is anticipated that this research will provide the theoretical rationale for elite kayakers to see the need to personalise their blade size based on their own muscle power profiles.  相似文献
