合作学习中自我监控的探析

运用情境实验和问卷测量的方法,可以测量合作学习中自我监控水平不同的学生在合作学习的小组活动自评中的差异.自我监控高的学生比自我监控低的学生对组织者有更积极的评价,但在对合作学习的喜爱程度上却比不上自我监控低的同学.     

大孔吸附树脂柱色谱法分离纯化重楼皂苷过程中的质量控制与评价

以重楼根茎粉末为原料,加热回流提取粗皂苷后,用近红外在线检测AB-8大孔吸附树脂除杂和洗脱分离的全过程,并以近红外光谱判别变量为表征手段,将分离过程分为四个阶段。分别对每个阶段收集的洗脱液进行比色和水解,通过离线的紫外光谱和高效液相色谱分析,结果显示,用70%的乙醇对大孔吸附树脂中除杂以后的重楼总皂苷进行洗脱,基本能将重楼总皂苷分为几类有效组分群。     

论高校后勤人力资本投资与收益的不对称性

当前我国高校后勤人力资本投资与收益不对称性的主要原因是:目前的管理体制约束了人力资本投资的不足,劳动收益的不对称造成人力资本的进一步流失,从而影响了经济的发展。高校可采取加大人力资本投资、加强人事制度改革、建立健全激励机制、增强企业文化建设等一系列措施来克服这一矛盾。     

Students working online for group projects: a test of an extended theory of planned behaviour model

This study examined an extended theory of planned behaviour (TPB) model that specified factors affecting students’ intentions to collaborate online for group work. Past behaviour, past experience and actual behavioural control were incorporated in the extended TPB model. The mediating roles of attitudes, subjective norms and perceived behavioural control were also examined. Data were collected from primary and secondary students in Hong Kong (N = 957). The partial least square approach to structural equation modelling was used to analyse the a priori hypothesised model. In general, the model fitted the data very well and the major relationships were found to be significant. The results indicated that past experience and actual behavioural control played individual roles in the model. Theoretical and practical implications are considered in this study.     

Requisite participant characteristics for effective peer group mentoring

Effective mentorship, due to the developmental nature of the experience, hinges upon the people involved—specifically, the personal characteristics of the mentoring collaborators. In this paper, the author explored requisite participant characteristics for peer group mentoring. One dozen executive-level professional women shared their stories-of-experience as participants in peer mentoring groups. A thematic analysis was utilized to investigate the narrative data from these interviews. Findings suggest that these participant characteristics include (a) an intrinsic interest; (b) a learning disposition; (c) a commitment to the mentoring experience; (d) comfortability with vulnerability and having the courage to share struggles; and (e) an inherent desire to support others in their learning, growth, and development.     

电磁波穿过DNG媒质时的传播特性分析

针对广泛关注的DNG媒质(负折射率媒质),以有损耗的Drude型媒质为模型,对电磁波穿过DNG媒质的平行板时的传播特性做了理论分析;采用FDTD方法对正弦电磁波穿过DNG媒质的平行板的传播过程进行了数值建模,数值模拟的结果证明了正弦电磁波在穿过DNG媒质的平行板时仍然具有相速度与群速度方向相反的特性,为DNG媒质的广泛应用提供了理论基础.     

浅析陈十四信仰的畲族民族化

陈十四信仰主要分布于闽浙粤台等地。这一信仰不仅在汉族社会广为流传,而且深入到畲族社会,并完美地与畲族文化融合,并在畲族人民的生活中展现出民族个性。通过对畲族民间文学、民俗生活和音乐舞蹈中陈十四信仰表现的论述,认为陈十四信仰的畲化主要源于畲汉共通的师祖关系、畲族自身的内部需求、民族生存的外部认同和强势文化的民族融合。     

网络环境下学习策略群体差异研究——基于陕西师范大学《现代教育技术》网络课程的研究

为了解学习者网络学习策略在不同性别、学历及学科背景间的群体差异,该研究在对网络学习策略的内涵及结构进行重新分析的基础上,以参与陕西师范大学《现代教育技术》网络公共必修课的1713名本科生和教育硕士为研究对象,采用问卷调查法对学习者的网络学习策略使用水平进行调查。通过对研究数据进行方差齐性检验、独立样本T检验以及单因素ANOVA分析,结果表明:网络学习中,学习者的信息素养策略、资源管理策略、合作交流策略以及自我调节策略在性别、学历及学科背景间均存在显著性差异,反思性学习策略无显著性群体差异。     

The Cultural Attitudes Towards Cooperative Learning: What Proverbs Can Offer

ABSTRACT

Cooperative Learning (CL) is acclaimed for its effectiveness, but is not widely used, partly because the role of culture in its implementation is overlooked. To fill this gap and to introduce an alternative methodology for the study of culture, this interdisciplinary paper examines Iranian proverbs to see how Iranians' culture feels about group work and what psychosocial factors contribute to their attitudes. The findings suggest Iranians’ culture, notwithstanding its potentiality for cooperation, is relatively non-cooperative. This ambivalence was observed to originate culturally from distrust, egoism, antipathy towards reciprocal altruism, and diffusion of responsibility. These findings substantiate the functionality of this alternative methodology.     

我国网络科技期刊开放访问现状及利用对策浅析

“开放访问”是近年采兴起的学术出版方式和学术成果无障碍交流模式，受其影响我国一些科技期刊也通过网络向用户提供免费全文的开放访问服务，表现为学科分布不均衡、服务方式和文件格式多样化及质量较高等特征。图书情报界和个人用户应积极采取应对策略，以促使我国科技期刊开放访问学术资源的充分利用。
