汉语对国外学生语言教学的重要性分析     

雷蕾 《南昌教育学院学报》2011,(9):174-175

目前汉语对国外语言教学研究仅仅局限于最初的阶段,与之相关的著作及教材非常少。面对国外学生汉语教学的重要性不能忽视,学生自身的文化语言背景直接对学习新的一门语言有一定的影响,我们要对不同国家学生所处文化环境进行差异分析,进行有针对性的教学辅导。本人通过对学生的问卷调查及个别采访,对欧美和日韩学生之间的语言差异进行重点分析,从这些差异对国外学生的语言教学的重要性进行思考与分析。  相似文献

数据驱动的微信用户信息行为时间特征研究     

张大勇  孔洪新  许磊  景东 《图书情报工作》2019,63(20):104-111

[目的/意义]相对于传统的信息行为分析，数据驱动的信息行为研究更注重数据的外在性与客观性，所得的结果能够更为全面地认识用户信息行为本质特征。[方法/过程]通过自行构建的APP实现对微信用户分享和阅读行为记录的采集，并对微信用户信息行为的时间特性进行系统的分析。[结果/结论]结果表明：微信用户日常信息行为存在显著的假日效应，但是在信息行为时间间隔分布上存在明显厚尾现象和很强的阵发性，预示着微信用户信息行为具有较高的复杂性和不确定性，无法对其产生过程实现有效的预测；此外，微信用户所分享的内容具有很强的时效性，多数内容在微信中能够得到及时的传播，但传播链长度显著受分享内容主题的影响。  相似文献   

Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor     

Haicheng Li  Yinji Ma  Ziwei Liang  Zhouheng Wang  Yu Cao  Yuan Xu  Hua Zhou  Bingwei Lu  Ying Chen  Zhiyuan Han  Shisheng Cai  Xue Feng 《国家科学评论(英文版)》2020,7(5):849

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.  相似文献   

大型赛事赞助、网络关注度与企业市场价值--2018年俄罗斯世界杯中国赞助商实证研究     

付磊  蔡兴林 《体育科学》2020,(4):28-34

企业赞助大型体育赛事目的是为了提升企业的市场价值,针对多家中国企业赞助2018年俄罗斯世界杯的事件,用事件研究方法考察了企业签约赞助和开赛日2个阶段股票价格的异常收益波动,并用百度指数研究了网络关注度对异常收益的影响关系。研究发现,中国企业赞助俄罗斯世界杯,在签约事件窗口内企业获得正向的市场绩效,而在开赛日事件窗口内企业获得负向的市场绩效。百度指数与股票异常收益的关系,说明网络关注度对事件影响产生催化剂的作用。研究结果表明,企业赞助大型赛事需要注重短期和长期的效果,注意防止过度炒作,并要积极采用营销组合的手段扩大赞助带来的影响和收益。  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   

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   

浅谈通过化学实验实施学生的探究性学习     

曹建红 《西北成人教育学报》2007,70(2):79-80

化学实验所具有的获知、激趣、求真、循理、育德的教育功能,决定了其是实施探究性学习的有效途径。中学化学教学中,通过化学实验来实施探究性学习必须创设真实的问题情境,并且充分发挥化学实验的探究功能。  相似文献

从封闭走向开放--研究生培养模式的重构与思考   总被引：6，自引：0，他引：6  

操太圣  雷万鹏 《教育发展研究》2005,25(10):15-19

当人们对我国现行研究生培养模式给予一定程度的关注时,往往会产生如下印象:即无论是研究生培养过程中所设置的课程体系、教学方式、师资组成,还是大学与科研机构的关系,与社会的结合程度,乃至于与外国同行的交往方式,均呈现出相当严重的封闭性.一定意义上,"封闭性"正暴露出我国研究生培养模式的症结所在.本文希望对研究生培养过程中存在的一系列现象进行剖析,将各种习以为常的现象"问题化",进而讨论可能的思考方向和可行的改革路径.  相似文献
