论当代西部生态小说的表征及形成原因

在中国生态文学创作和研究日臻成熟的今天,当代西部生态文学的创作也呈现出了繁荣的趋势,并逐渐形成了独特的面貌,开创了西部文学崭新的局面。探讨当代西部生态小说的一些基本表征及其形成的原因,并以此来进一步深化我们对当代西部生态小说特质的认识和研究。     

身体力行"三个代表"努力构建山西远程开放教育新体系

江泽民总书记“三个代表”的重要论述，是我党的立党之本、力量之源、生命之基，是教育改革的思想武器，也是构建山西远程教育新体系的指导思想。身体力行“三个代表”，就是要搞好高校党建特别是领导班子建设，培育“四有”新人，促进先进化发展，积极推进山西电大改革，满足先进生产力发展的要求，最大限度地满足社会发展和人民群众对教育的需求，为山西经济建设和社会发展服务。     

不同迁移方式与不同学习“方式”对知觉运动序列学习的影响——一项ERP研究

拟采用迁移范式,以事件相关电位(ERP)成分N2、P3作为主要指标,结合不同迁移方式和不同学习"方式"探讨学习者的知识表征方式的差异。结果发现:内隐组和外显组被试在习得了一定的序列知识后,相对于标准序列的反应时,效应器迁移序列的反应时明显变慢;在脑电数据中,以N2的平均波幅作为指标,不管是内隐组还是外显组,标准序列与刺激迁移序列不存在区别,而与效应器迁移序列却差异显著。对于P3的平均波幅的分析得出:在内隐组,标准序列与效应器迁移序列不存在区别;而在外显组,两者却差异显著。该结果说明:效应器水平的编码机制是参与序列知识的学习的;且相对于知觉编码,不管以何种"方式"学习,效应器编码起的作用都要更大。     

Does teaching students how to explicitly model the causal structure of systems improve their understanding of these systems?

If students really understand the systems they study, they would be able to tell how changes in the system would affect a result. This demands that the students understand the mechanisms that drive its behaviour. The study investigates potential merits of learning how to explicitly model the causal structure of systems. The approach and performance of 15 system dynamics students who are taught to explicitly model the causal structure of the systems they study were compared with the approach and performance of 22 engineering students, who generally did not receive such training. The task was to bring a computer-simulated predator-and-prey ecology to equilibrium. The system dynamics students were significantly more likely than the engineering students to correctly frame the problem. They were not much better at solving the task, however. It seemed that they had only learnt how to make models and not how to use them for reasoning.     

Using mobile devices to enhance inquiry-based learning processes

Technological advances offer the possibility of using mobile devices to enrich learning environments with multimedia content. Although physical experiments play a key role in science learning, little is known about integrating multimedia learning in physical experimental processes, especially in realistic classroom settings. In our approach, students use tablets to investigate motion with an application providing multiple representations of the measurement data. We present the results of a cluster-randomized controlled study with high school students (average age = 15.6, N = 286) conducted between 2017 and 2018 in 11 secondary schools in Germany. Conceptual understanding of physics, cognitive load, and assessment of teacher behavior were surveyed. Multilevel regression analysis revealed that this approach leads to a significant reduction of extraneous cognitive load and to greater conceptual knowledge. A confirmatory path analysis revealed that these effects can be traced back to the treatment and are not significantly influenced by teacher behavior.     

Collaborative talk in mathematics – contrasting examples from third graders

There is a substantial body of knowledge on the importance of language for learning in general, and for learning mathematics in particular. Hence, language skills and collaborative learning are emphasised in the Norwegian curriculum. Even so, we have few studies on what supports and what impedes mathematical progress in authentic learning situations. In this article, we investigate contrasting dialogues between two pairs of eight-year-old pupils solving mathematical tasks. The analysis in our video-based study shows that both communication skills and use of tools have a profound impact on third graders’ potential to solve tasks as a joint enterprise.     

《金瓶梅》"我化"史实例评--天水籍官员狄斯彬本事考释

<金瓶梅>在写政治人物时涉及到了一个天水籍官员狄斯彬,历史上真有其人.和史实比较,小说中的人物既有艺术真实,也有历史真实.但小说作者对史实改造过多,容易形成人们对这个历史人物的误解,需要辨明.同时,由塑造这个人物可以体察<金瓶梅>写官员时所用的史实"我化"手法.还可以由作者对狄斯彬的熟悉程度推测小说的创作时间和作者的身份.     

坚持党的性质增强党的基础

坚持党的性质,就要以"三个代表"思想为指针,牢牢把握工人阶级是我们党不可动摇的阶级基础,从而增强党的基础,扩大党的群众基础,进一步加强党的建设.     

在高校全面贯彻"三个代表"的思想--学习江泽民同志"七一"讲话的体会

本文通过对江泽民同志"七一"讲话的学习,从高校应树立正确的育人观和高校如何成为先进文化的发祥地两个方面阐述了作者的基本观点.     

个人人际情报网络分析在中小企业中的应用研究

人际情报网络分析是企业竞争情报研究的重要内容,个人人际情报网络分析是其中一种重要分析类型,它尤其适合于中小企业行动者。本文在前期研究“基于结构洞理论的个人人际网络分析系统研究”基础之上,选取一个中小企业为研究对象,利用所开发的分析系统,对该企业行动者的个人人际情报网络进行了分析,并提出了若干利用和调整其人际情报网络的建议。实践证明,对中小企业行动者实施个人人际情报网络分析,有利于行动者理清和调控自身人际情报网络,同时也是我们将竞争情报研究成果应用于企业实践的有益尝试。
