Making Multimedia in the Classroom: A Teachers' Guide

Interactive relationships in online learning communities can influence the process and quality of knowledge building. The aim of this study is to empirically investigate the relationships between network structures and social knowledge building in an asynchronous writing environment through discussion forums in a learning management system. The quality of the knowledge construction process is evaluated through content analysis, and the network structures are analyzed using a social network analysis of the response relations among participants during online discussions. Structural equation modeling is used to analyze relations between network structures and knowledge construction. Working on data extracted from a 6-week distance-learning experiment, we analyzed how 10 groups developed collaborative learning social networks when participants worked together on case resolution. The results show a positive correlation between cohesion and centralization, and the positive influence of the cohesion index and the centralization index on social presence and cognitive presence in knowledge building. However, this must be understood within the context of social networks in which messages sent to all group members occupy the center. This underlines the need for reinforcing participations that are directed to the group as a whole, and the importance of the fact the network contains both central and intermediate members. By contrast, we propose that the combination of analysis techniques used is a good option for this type of study while recognizing that it is necessary to continue validating the instruments in terms of their own theoretical suppositions.     

Discourse measures for Basque summary grading

In the context of Learning Technologies, the need to be able to assess the learning and domain comprehension in open-ended learner responses has been present in artificial intelligence and education since its beginnings. The advantage of using summaries is that they allow teachers to diagnose comprehension and the amount of information remembered from text in the learning process. This study addresses the issue of automatically obtaining overall discourse scores from surface discourse measures for Basque language. Global measures have been studied for cohesion, adequacy and use of language. The approach taken was to estimate the presence of the automatically gathered surface discourse measures in expert grading decisions in cohesion, adequacy and use of language. As a consequence, three grading decision-making regression models were obtained to estimate overall grades from text written in Basque. Next, the obtained regression models were tested in corpus-containing summaries written by learners with different degrees of summarisation maturity. The results show that the obtained grading frameworks significantly reflect human decisions and are able to discriminate summarisation maturity differences.     

语境对词义演变和词义运用的影 响

从语境与词义的定义入手,结合相关语料,剖析语境对词义演变和词义运用产生的影响。结果表明,语境不仅是导致词义演变的一个重要因素,而且还会影响到词义组合在语言中的具体运用。     

从USA Today和China Daily网站看英语新闻标题用词的特点

英语新闻标题用词丰富多彩。从USA Today以及China Daily网站获取语料,建立英语新闻标题的语料库,来分析这些用词特点：多使用小词、缩略词及复合词;频繁使用新词和外来词;俚语、省略、借代等大量涌现。从而为新闻标题的翻译提出建议。     

略论英语语篇的词汇衔接手段

功能语言学从语言本身的角度详尽而系统地分析了语篇的连贯,揭示了词汇衔接对语篇连贯的作用.词汇衔接可分为复现关系和同现关系两方面,是英语语篇衔接的最重要手段之一.     

翻译中词汇空缺现象的认知解读

从认知的角度看,词汇空缺的形成既可能是由于不同的文化或生活经验而导致的概念缺失,也可能是由于不同民族概念化差异而导致的语义域错配(dismatch between semantic fields)。词汇空缺在翻译中可以通过“音译”、“意译”和“诠释”等多种手段进行处理。通过“音译”或“意译”产生的某些“借词”(borrowed word或loan word),久而久之有被目的语吸收,从而弥补词汇空缺的倾向。     

衔接教学在中学生英语说明文写作中的应用

衔接是连贯性的基础和具体体现,在英语运行机制中起着非常重要的作用.根据以往的研究背景以及目前中学生英语写作教学现状,笔者针对高三学生进行了为期五个月的衔接教学训练.利用Halliday和Hasan的语篇衔接和连贯理论,分别对实验班和控制班的成绩进行了对比研究,发现衔接教学可以有效影响和提高学生的写作能力.

Appreciation of Hardy＇s poem ＂Neutral Tones＂ from the point of view of functional analysis

According to the theory of Systemic-Functional Linguistics （SFL）, language cannot be disassociated from meaning. Function and semantics, as SFL suggests, are considered as the basis of human language and communicative activity. In order to reveal the inseparability of language and semantic, this paper aims to analyze and appreciate Hardy＇s poem ＂Neutral Tones＂ as a piece of literary work based on the theory of functional analysis specifically on field, tenor and mode.
