我国图书情报领域期刊论文的科学数据引用特征研究     

丁文姚  李健  韩毅 《图书情报工作》2019,63(22):118-128

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。  相似文献   

基于用户兴趣度量的知识发现服务精准推荐     

丁梦晓  毕强  许鹏程  李洁  牟冬梅 《图书情报工作》2019,63(3):21-29

[目的/意义]针对当前知识发现服务中存在的个性化程度不高和推荐效果不佳等问题，提出一种基于用户兴趣度量和内容分析的推荐算法。[方法/过程]文章通过特征词分布、LDA主题分布、引文结构网络三个维度构建学术资源模型，并通过对用户行为的度量，计算用户对其浏览学术资源的兴趣度，结合学术资源模型构建用户兴趣模型。将用户兴趣模型与学术资源模型匹配，计算其相似度，得到用户对每条学术资源的兴趣值，最后将兴趣值最高的TOP-N学术资源推荐给用户。[结果/结论]通过实验检验算法的有效性和推荐准确率，结果显示，本文从实时动态度量兴趣的角度，提出的推荐算法能较好地预测用户兴趣，推荐效果显著，为实现发现服务精准推荐提供思路。  相似文献

Xin Yuan 《中外文化交流(英文版)》2014,(12):16-17

On October 17, a unique show of mechanical dragon-horse was unveiled at the Olympic Park in Beijing in celebration of the 50th anniversary of China-France dip-lomatic relations. The three-day event teatures an eight-act performance, with each act lasting one and half hours. On the first day, the dragon-horse and the spider came to life to appear in the Olympic venue. the two mythical each other when On the second day, beasts fought against the spider set a trap in an attempt to capture the drag- on-horse.  相似文献

教师实践智慧的五种常见误解及其澄清——基于循证教育学的视角     

杨文登  谈心 《教师教育研究》2016,(4):1-7

关于教师实践智慧的讨论曾存在以下5种观点:(1)教师实践智慧是教师关于如何做的知识、能力或经验;(2)教师实践智慧具有动态性,依赖于具体情境;(3)教师实践智慧具有缄默性,以难以言说的方式而存在;(4)教师实践智慧具有直觉性,通过反思或体验而获得;(5)教师实践智慧具有个人性,难以学习与传播。长期以来,人们似乎已经习惯并认可这些观点。但从循证教育学的视角来看,它们可能是分别针对教师实践智慧的概念、特征、存在方式、生成手段与传播可能性等存在的误解。混淆实践智慧与实践的界限、概念引入的逻辑倒挂以及教育学缺乏操作性定义的研究氛围等,是导致这些误解的重要原因。  相似文献   

A Meta-Analysis of Single-Case Research on Mathematics Word Problem-Solving Interventions for English Learners with Learning Disabilities and Mathematics Difficulties     

Qingli Lei  Rose A. Mason  Yan Ping Xin  John L. Davis  Marie David  Catharine Lory 《Learning disabilities research & practice》2020,35(4):201-217

This single-case meta-analysis is the first to provide a quantitative synthesis of the published literature on mathematics word problem-solving intervention studies for English learners with learning disabilities and mathematics difficulties. A total of ten single-subject studies were included for analysis. The current study investigated the magnitude of the effect of mathematics interventions targeting the improvement of students’ mathematics word problem-solving performance, and analyzed variables that moderated this effect. Results indicate a moderate overall effect size of 0.81 (95% CI [0.71, 0.90]) on word problem-solving performance for English learners with learning disabilities and mathematics difficulties. Moderator variables such as the implementer of the interventions, instructional focus, and word problem-solving content significantly moderated the mathematics intervention effects.  相似文献   

网络多媒体教学的辅助功能定位及实践     

丁荣荣 《科教文汇》2013,(8):44+46

实践表明,部分教师在应用网络多媒体进行教学时却忽略了主体性的发挥,这一问题将严重削弱专业课程的教学效果。为此,应将网络多媒体技术严格定义在辅助功能的角色,并通过纠正教师教学的主观意识、完善教师教学的内容设计,以及强化教学效果的多方评价来优化网络多媒体教学的实践。  相似文献   

The Effect of Visual‐Chunking‐Representation Accommodation on Geometry Testing for Students with Math Disabilities     

Dake Zhang  Yi Ding  Joanna Stegall  Lei Mo 《Learning disabilities research & practice》2012,27(4):167-177

Students who struggle with learning mathematics often have difficulties with geometry problem solving, which requires strong visual imagery skills. These difficulties have been correlated with deficiencies in visual working memory. Cognitive psychology has shown that chunking of visual items accommodates students’ working memory deficits. This study investigated the effects of visual‐chunking representation as a testing accommodation for improving students’ geometry problem‐solving performance. Participants were four third‐graders with difficulties in mathematics. An adapted reversal design was employed to examine the students’ performance changes during standard testing conditions and accommodated testing conditions. During the accommodated condition, students were presented with visual‐chunking images. Results suggested that the visual‐chunking representation accommodation improved students’ performance on geometry problem‐solving tasks, and an interview confirmed students’ preference for the visual‐chunking representation approach.  相似文献
