As information and communication technologies (ICTs) become increasingly prevalent in modern society, improving students' competency with these technologies has become a key focus of 21st century education. Given the interdisciplinary and information rich nature of ICTs, many advocate for school librarians to actively promote their integrative use across the K-12 curriculum. This article asks, “Are school library media professionals adequately prepared for the task of integrating technology and skills into instruction?” It explores the perceived ICT competencies of students enrolled in school library certification programs and the use of ICTs in their school library education programs. Factors identified for discussion include the age of students enrolled in school library certification programs, the evolutionary process of ICT curricular integration, and perceived preparedness to integrate ICTs into instruction despite self-reported low competency levels with many of emerging technologies. Concluding comments encourage design of authentic and meaningful learning experiences that incorporate and promote the integrative use of ICTs in school library certification programs. 相似文献

Research Findings: Digital play is now commonplace in many young children’s lives, but not in preschool settings. This situation is likely due to the fact that the existent literature seldom highlights what digital play looks like, the various ways it can be situated, and what young children do when they play together with digital devices in the preschool setting. The present study addresses this limitation by providing a close examination of the social interactions of young children as they engage with different types of iPad apps and each other. Observational data of 20 dyads of children during digital play analyzed qualitatively revealed that children exhibited a range of social behaviors from competitive to collaborative as they engaged in 4 types of digital play: practice/task, exploratory, construction, and pretense. Forms of play and exhibited behaviors were shaped by interrelated factors of children’s individual characteristics and relationships, classroom culture and routines, adult views and actions, as well as aspects of the digital device itself. Practice or Policy: Selecting open-design apps, attending to digital play structures, and monitoring peer play more closely may lessen competition, enhance collaboration, and lead to more complex digital play. 相似文献

Participation in organized sports is promoted as a means of increasing physical activity levels and reducing chronic disease risk in adults. Hard martial arts practice (i.e. using body contact techniques), has gained in popularity over time. This review explores the evidence for health benefits of “hard” martial arts practice within the adult population. A systematic electronic database search was conducted, and quality assessments applied the Effective Public Health Practice Project tool. Twenty-eight studies met the inclusion criteria, examining balance, cognitive function, muscular skeletal status, psychological, cardiovascular fitness, and metabolic effects. The majority of studies reported positive effects resulting from hard martial arts practice, showing some improvement and maintenance of balance, cognitive function and psychological health. Benefits may be obtained regardless of the age of practice commencement. However, quality of the evidence is affected by methodological weaknesses across the studies. “Hard” martial arts seem to have potential to improve balance and cognitive functions that decline with age, which can lead to poorer health outcomes among the elderly (e.g. cognitive decline, falls and fractures). Benefits should be further investigated with improved intervention studies, representative samples and longer follow-up periods in order to establish associations with morbidity and mortality in the long term. 相似文献

In Paralympic sports, biomechanical optimisation of movements and equipment seems to be promising for improving performance. In handcycling, information about the biomechanics of this sport is mainly provided by case studies. The aim of the current study was (1) to examine changes in handcycling propulsion kinematics and kinetics due to increasing workloads and (2) identify parameters that are associated with peak aerobic performance. Twelve non-disabled male competitive triathletes without handcycling experience voluntarily participated in the study. They performed an initial familiarisation protocol and incremental step test until exhaustion in a recumbent racing handcycle that was attached to an ergometer. During the incremental test, tangential crank kinetics, 3D joint kinematics, blood lactate and ratings of perceived exertion (local and global) were identified. As a performance criterion, the maximal power output during the step test (Pmax) was calculated and correlated with biomechanical parameters. For higher workloads, an increase in crank torque was observed that was even more pronounced in the pull phase than in the push phase. Furthermore, participants showed an increase in shoulder internal rotation and abduction and a decrease in elbow flexion and retroversion. These changes were negatively correlated with performance. At high workloads, it seems that power output is more limited by the transition from pull to push phase than at low workloads. It is suggested that successful athletes demonstrate small alterations of their kinematic profile due to increasing workloads. Future studies should replicate and expand the test spectrum (sprint and continuous loads) as well as use methods like surface electromyography (sEMG) with elite handcyclists. 相似文献

The questions asked at the traditional reference desk are decreasing while questions asked at the virtual reference desk are on the rise. Over a one-month period, the types of reference questions asked at an academic health sciences library were coded. This paper examines and compares the types of questions asked at the current day reference desk versus the virtual reference desk. This paper also reviews past literature examining the types of questions asked via virtual reference and the traditional reference. 相似文献

This paper presents a case study of the development of a multimedia training product for broad distribution to middle and senior management as well as university students. It compares anticipated and actual costs of project management and where possible makes comparisons with data from similar projects. An unexpected finding was a greater than twofold overrun on the anticipated costs of project management. The greater part of this overrun was an increased administrative effort required to comply with reporting requirements of the funding body and the joint Venture partnership. The results of this study have implications for producers of interactive multimedia in higher education with regard to realistic costing of project management, which is often an unfunded contribution. 相似文献
