采用文献资料、逻辑分析等方法对近10年中国青少年体质健康的现状、影响因素、干预策略、监测与评价标准等进行综述。结果表明,青少年体质健康逐年下降,影响因素主要包括学校、家庭和社会,干预策略主要包括运动和改善体育场地设施,监测与评价标准有待完善,青少年体质健康服务有待建立等。     

90年代《儒林外史》研究述评

90年代的《儒林外史》研究是继 80年代全面繁荣以后又一高峰。经过老中青三代研究者的努力 ,过去传统论题的研究得到深化 ,新的研究方法的运用又使其领域得到拓展。对 90年代这些研究成果加以总结和评论是非常必要的     

国外高等教育服务质量SERVQUAL模型研究及其启示

高等教育具有无形性,异质性,不可分离性,多变性,不可贮存性,及顾客(学生)参与服务过程等服务产业的所有特征。然而与其他服务产业相比,高等教育服务质量的研究相对被忽视。本文对国外学者利用SERVQUAL模型研究高等教育服务质量进行文献综述,同时认为,国外学者的研究有如下几个特点。第一,认为高等教育服务是高等教育的基本产出之一,学生是高等教育中最重要的利益相关者;第二,PZB的服务质量差距分析模型是高等教育SERVQUAL测量的理论基础,高等教育服务质量、学生满意度和学生行为倾向之间存在相关关系;第三,SERVQUAL方法适用于各个类型、层次的高等教育服务质量测量,但必须对其维度及其指标进行修正;第四,SERVQUAL测评是院校研究的一种手段,可以提高大学在市场中的竞争力。     

Voices of teacher candidates of color on white race evasion: ‘I worried about my safety!’

Abstract

This qualitative study investigated the negative impacts minority teacher candidates receive from white teacher candidates in a required multicultural education class. The findings reveal that four teacher candidates of color had difficulty positioning themselves among the overwhelming silencing power of whiteness in the class. The white students were tactful at evading power and race and flattening the existing hierarchical power relations through the discourses of colorblindness and by preying on the minority instructor. Their understanding of diversity was also shallow. On the other hand, the teacher candidates of color were afraid that they might be labeled as the ones who spoke up against the white students and fearful of the possibility of retaliation and ostracism from the white peers. It seems that the teacher education program’s structure allowed the white candidates to impose strong negative peer pressure on the teacher candidates of color.     

Defining the nature of blended learning through its depiction in current research

ABSTRACT

Blended learning has been a feature of higher education practice and research for almost two decades. This article takes stock of current blended learning research, contributing to the growing number of meta-analyses of higher education and blended learning research more generally, through a review of ninety-seven articles relating to blended learning in higher education published in fifteen journals between 2012 and mid-2017. The review focused on where and when the articles were published; their provenance, scale, scope; methodological approach; the broad research themes; and definition of blended learning used. The review shows that despite its ubiquity, blended learning’s definition is all-encompassing; its spread is global but research is dominated by key players; it is of technical interest; and its research is small-scale, individually focused, seeking to evidence the benefits of blended learning. The article concludes with recommendations of how higher education research could provide institutions with evidence to ensure their ‘best of blends’.     

对比修辞:英汉书评比较

书评，作为一种新型写作体裁，同样反映化差异。英美学术书评侧重描述，汉语学术书评则侧重评价；英美书评批评性较强，汉语书评批评性却较弱。两种书评在修辞结构和评价策略上的差异与其不同化背景和风俗习惯有很大联系。     

英语语法三大主要流派述评

英语语法研究经历了几个阶段,出现了若干不同的流派,其中最有影响的是传统语法、结构语法和转换生成语法.这三种语法理论,各有优劣.它们都对语言学的研究和发展作出了各自的贡献,产生了不可磨灭的影响.     

A review of ‘psychology and the study of education: critical perspectives on developing theories’

This review examines Psychology and the Study of Education: Critical Perspectives on Developing Theories, a collection of academic articles edited by Cathal Ó Siochrú. The collection comprehensively considers wide-ranging topics pertinent to the psychology of education, with a target audience of educators and students wishing to learn more about psychology. The review evaluates the collection as an integrated work of entries and analyses each component chapter; recognising the success of the collection with respect to its aim of challenging readers to critically reflect upon and consider the value of psychology in both understanding and influencing education. The book transcends the common formula of academic article collections in this area by being presented in a somewhat conversational manner, making it both interesting and accessible. The book is recommended for anyone interested in the psychology of education and for anyone who values the advancement of learning and teaching.     

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.     

校阅在CAT与FIT中对受测者行为表现与状态焦虑水平的影响

校阅(review)对CAT中受测者心理影响的研究有利于CAT的推广应用。J.Oleat等研究者在CAT(computerizedadaptivetest,计算机自适应性测验)与FIT(fixed-itemtest,固定项目测验)中,将校阅(review)对受测者行为表现与状态焦虑水平的影响作了比较研究。实验结果表明,在允许校阅的环境中,受测者正确反应与被估计的能力水平显著增加,并且状态焦虑水平下降。本文对J.Oleat等研究者的主要研究成果进行了详细的评述,并进一步探讨了在CAT中增设校阅(review)环境的重要性和可能性。
