The information age has given library media specialists an unprecedented opportunity to play a leading role in helping teachers, administrators, and especially students access and use information intelligently. As the school??s premier information specialist; the library media specialist has a unique role to play in helping everyone in the school develop a true twenty-first century habit of mind: a habit of thinking about information itself as a basic and powerful tool for learning deeply and living well in the information age. This article explores this role in the ??brave new?? digital age and offers a number of collaborative strategies that can help the library media specialist work with the entire school community. 相似文献

An increasing number of college students enrolling with poor reading fluency and comprehension skills pose a significant challenge to the college reading field in the absence of a strong understanding of the construct of reading fluency and its instruction. In order to contribute to this area of college reading, this article discusses instructional components that have been found to be effective in previous research in terms of their effectiveness and applicability for building fluent reading skills in struggling college readers. 相似文献

Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake. 相似文献

The aim of this study was to investigate videos as potential triggers of behavior. Therefore, we applied the theories of triggers and media richness to learn about the triggering efficiency of mobile marketing videos on participants’ behavioral intentions. The experiment involved three distinct test groups, each comprising 41 student participants. From the perspective of media richness theory, we observed that the different kinds of videos had quite similar effects in terms of triggering behavioral changes. However, the mechanisms explaining why triggers were present differed for each video. Further, the results reveal that the consumer's position in the information search process was the most significant reason for the triggering of any kind of effect. In addition, the instructionally designed videos were able to exert an affective triggering effect: the more participants liked the video, the more it affected their participation intention and recall scores. This study extends the media richness research by demonstrating that the effects of media richness can vary within technically similar videos, as they form different logical connections among non-verbal visual cues related to a video's storyline. 相似文献

The selection of books to read to young children matters enormously in the role books play for enriching children’s lives.
This paper reviews the scientific evidence for the appropriate selection of books, and argues that care in selecting books
targeted to children’s developing skills will enhance the power and the pleasures of reading to young children. 相似文献

In this paper, it is argued that e‐learning environments are currently more like ‘buildings’, ie, learning spaces, rather than ‘schools’, ie, places for learning. The concepts originated from architecture and urban design, where they are used both to distinguish static spaces from inhabited places, and more importantly, as design objectives. The transformation from space to place is supported and enabled by social interactions between the (learning) community members. We argue that this distinction between the concepts explains some of the problems with current e‐learning systems and propose issues to consider when designing new systems. By acknowledging the importance and characteristics of a place, designers and researchers can justify the need and support for social interactions in learning space, consequently enabling social community building in e‐learning environments, and most importantly, supporting the development of a user‐friendly and motivating e‐learning place. 相似文献

This article investigates the extent to which there exist differences in standards for awarding first degrees with distinction amongst universities in Israel (as measured by the percentage of total graduates each year that receive a distinction). Based upon an analysis of annual data for the period 1979–1983, considerable diversity was found in the tendency to award first degrees with distinction between and within universities and faculties, and between the major subject department of the social science faculty, selected for more detailed analysis.This heterogeneity parallels that reported in Nevin's work relating to the situation current at universities in the United Kingdom nearly two decades ago. 相似文献
