This study investigated the effectiveness of e-learning by comparing the learning outcomes in conventional face-to-face lectures and e-learning methods. Two video-based e-learning contents were developed based on the rapid prototyping model and loaded onto the learning management system (LMS), which was available at http://www.greenehrd.com. Eighty-five Korean agricultural high school students were randomly assigned into the two groups: face-to-face lecture (control group), and video-based e-learning (experimental group). The students of the experimental group logged onto the LMS in the school computer lab and completed each e-learning module. All students were required to take a pretest and posttest before and after learning under the direction of the subject teachers. One-way analysis of variance (ANOVA) was used to examine any difference between the two groups in terms of learning outcomes. One-way analysis of covariance (ANCOVA) was also administered to verify whether there was any difference between the two groups after controlling for the covariate variable: pretest score. According to the results, e-learning resulted in better learning outcomes than face-to-face lecturing. These findings suggest that the use of well designed and appropriately applied e-learning could be worthy even in agricultural education, which stresses hands-on experience and lab activities. Further research should focus on a different e-learning content type in different agricultural subject fields and its relationship with learning outcome.  相似文献   

Information privacy: a comprehensive analysis of information request and privacy policies of most-visited Web sites     

Jiyoung Cha 《亚洲交流杂志》2013,23(6):613-631

Obtaining consumer data has become an essential practice of Web proprietors. This is because, compared with ‘brick and mortar’ retail stores, it is much more difficult for Web proprietors to build one-on-one or face-to-face relationships with customers. The collection of personal information online boosts customized services for consumers, but at the same time it increases concerns about privacy infringement. Using a content analysis of the most visited Web sites in Korea and the United States, this study compares the amount and breadth of information requested by Web proprietors and examines the relationship between the information requests and privacy policies of Web sites. This study found that Korea-based Web sites present stronger privacy policies than do US-based Web sites. Ironically, they also request a greater amount and variety of information from consumers than do US-based Web sites during registration processes. When narrowing the focus to US sites only, this study also revealed that the stronger the privacy policies presented by US Web sites, the more information the US Web sites request from consumers.  相似文献   

A Theory of Sport and Politics     

Victor D. Cha 《国际体育史杂志》2013,30(11):1581-1610

The study of international relations purports to explain how nation-states and individuals interact around the globe. Yet one major area of such interaction – international sport – remains exceedingly understudied. This in spite of the fact that countries have gone to war over sport, fought for sovereign recognition through sport, and that citizens around the world have it as a daily part of their lives. Indeed it is astounding that a phenomenon that matters so much has been so little studied by a field that purports to explain relations between states and humans around the world. These deficiencies became more apparent in 2008 when we witnessed the world's biggest country hosting the world's biggest sporting event. The Beijing Olympics, though entertaining and exciting, showed how little we have thought about the link between sport and international politics. This article introduces a framework for understanding the link between sport and politics. Its point of entry is to argue that many of the questions about how China portrayed itself during the Olympics and whether the Games marked China's rise as a responsible power cannot be answered without first understanding how sport in general is related to a country's political development, and its sense of nationhood. My arguments do not represent new breakthroughs in political science, rather I attempt merely to offer a systematic way of thinking about how sports and the Olympics matter in world politics through three inter-related causal pathways relating to a country's sense of self, its diplomacy, and its capacity for change.  相似文献

Raising a Difficult Child: Interplay Among Children’s Negative Emotionality Traits,Maternal Parenting,and Children’s Cognitive Development     

Kijoo Cha 《Early education and development》2018,29(8):1095-1114

Research Findings: The present study examined (a) whether children’s negative emotionality traits (anger proneness and unsoothability) interactively predict mothers’ authoritarian parenting (AP) and (b) whether children’s negative emotionality moderates the associations between AP and children’s performance on a spatial cognitive task. Eighty mother–child dyads were recruited from Seoul, Korea (children’s age = 45–66 months). The findings were as follows. First, when children were prone to anger and were simultaneously difficult to soothe, mothers were inclined to show more AP. However, when children were relatively low in either of the traits, such as when children were difficult to soothe but not prone to anger, higher levels of unsoothability were associated with less AP. Second, depending on the degree of children’s anger proneness, the associations between children’s spatial intelligence and AP varied. Among children with higher levels of anger proneness, less AP was associated with lower performance on a spatial cognitive task, whereas the opposite pattern was observed among children with lower anger proneness. Practice or Policy: This study implies that the configurations of temperamental traits and the levels of parental control need to be considered in designing teacher and parent education programs, probably in relation to the cultural context.  相似文献

媒体融合背景下中国高校学报发展现况分析及对策研究     

贾泽军  尹茶  邓晓群 《编辑学报》2016,28(5):474-477

采用文献计量分析、网络查询、电话问询等方法逐一调研中国高校自然科学学报媒体融合发展现况,为新媒体形势下高校学报改革提供决策依据.调研发现,中国高校学报媒体融合发展仍处于起步阶段,与大众传媒相比,其集团化、一体化程度低,数字化平台建设缓慢,“物理融合”阶段尚未完成,参与媒体推介积极性不高,且受不良论文代写群体干扰严重.认为当务之急必须首先着手解决高校学报媒体机构的初步融合,为高校学报可持续发展奠定基础.  相似文献

很长一段时间里,那句"卫生靠检查,体育靠竞赛,教育靠评估"的话颇为流行。因为这些年来,各类教育评估搞得相当热闹。如何看待各类评估?今年《中国远程教育》第六期刊首寄语——"评估教育",值得一读。文章说,2005年4月21日,教育部公布了对54所高校的评估结论,其中30所优秀,19所良好,5所合格。这一结论给人印象是中国高校教育质量令人放心,然而观察身边高校之情形,也许我们又会产生若干疑惑。  相似文献   

Adaptive peer-to-peer streaming with MutualCast     

CHOU Philip A 《浙江大学学报(A卷英文版)》2006,7(5):737-748

INTRODUCTION Many applications, such as software distribution, Internet TV/video streaming, video conferencing, multiplayer gaming, personal media distribution and P2P web content duplication, distribute the same content from one source node to many destination nodes. For these applications, IP multicast is an ideal network layer solution. A distribution tree rooted at the source can be formed to reach an arbitrary number of receivers. During content distribution, every single piece of…  相似文献
