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.     

An NCME Instructional Module on Polytomous Item Response Theory Models

A polytomous item is one for which the responses are scored according to three or more categories. Given the increasing use of polytomous items in assessment practices, item response theory (IRT) models specialized for polytomous items are becoming increasingly common. The purpose of this ITEMS module is to provide an accessible overview of polytomous IRT models. The module presents commonly encountered polytomous IRT models, describes their properties, and contrasts their defining principles and assumptions. After completing this module, the reader should have a sound understating of what a polytomous IRT model is, the manner in which the equations of the models are generated from the model's underlying step functions, how widely used polytomous IRT models differ with respect to their definitional properties, and how to interpret the parameters of polytomous IRT models.     

Towards the successful integration of e-learning systems in higher education in Iraq: A student perspective

This study aims to analyse the factors that can explain the adoption and effective use of a new e-learning system in Iraq. To achieve this, it uses a selection of factors that are present in the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT) model, and it includes three additional factors. The study hypothesises new relationships between the selected factors. Questionnaires were distributed to 300 university students in Iraq. Partial least squares-structural equation modelling (PLS-SEM) was used to analyse the data received. The findings suggest that perceived usefulness (PU), perceived ease of use (PEOU), subjective norms (SNs), information quality (IQ), system quality (SQ), technical support (TS) and self-efficacy (SE) have significant effects on behavioural intention (BI). In turn, BI and TS have significant direct effects on the actual use (AU) of e-learning systems. The factors age, gender and experience significantly moderated some of the relationships in the model. The research has several implications for policy makers, universities and the management of e-learning systems.     

Teaching the partial products algorithm with the concrete representational abstract sequence and the strategic instruction model

Elementary standards include multiplication of single-digit numbers and students advance to solve complex problems and demonstrate procedural fluency in algorithms. The ability to illustrate procedural fluency in algorithms is dependent on the development of understanding and reasoning in multiplication. Development of multiplicative reasoning provides the foundation for advanced mathematics and algebraic reasoning. For students who struggle in mathematics, instruction in multiplication algorithms should ensure conceptual understanding so that students have a foundation for success in advanced mathematics. The concrete representational abstract (CRA) sequence addresses conceptual understanding and the strategic instruction model (SIM) supports procedural knowledge. The current pilot study combined these methods to teach elementary students the partial products algorithm. Twelve students in grades four and five participated in the study, receiving instruction from teachers in their school during an intervention period. Within a pre-experimental design, using pre- and postintervention data, students showed a significant change in performance. The article will describe and show how teachers implemented the CRA-SIM interventions and discuss implications for practice.     

广播新闻的衔接策略分析

基于韩礼德的衔接理论,试图通过对《晚报浏览》节目中的新闻加以研究,从中找出新闻之间的衔接策略,以便对新闻语篇作出更加客观和科学的分析。     

关于五年一贯制高师课程计划的思考

课程计划是实现培养目标的根本和关键。五年一贯制高师课程计划要体现“直通车”和连贯性的基本特点 ,具有独创性和鲜明的一贯制特色 ,而不能是三年制中师课程计划和两年制高师专科课程计划的简单相加     

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.     

关联理论对语篇连贯的认知解释

连贯是语篇的基础,是一个复杂的语言现象,它涉及到语义、语用及认知等方面。功能语篇连贯的研究主要集中在从形式或语义角度进行考察,认为连贯是文本固有的语言现象。而关联理论的明示推理交际模式给我们提供了从认知的角度探讨交际中话语连贯的实现途径,在语篇话题对连贯理解的作用方面有较强的解释力。     

认知语用框架下的主述位衔接机制及语篇分析与教学

语篇的产生和理解是一个复杂的、动态的认知语用过程。从内部结构上看,一个衔接的语篇不是句子的堆砌,而是句子间的接口,每个句子都建立在前句的基础之上。从意义连贯上分析,新旧信息相互衔接,推动语篇的发展．从认知语用学的视角出发,研究语篇衔接与连贯必然涉及语篇的语境,应该考虑语篇编码的过程,既要分析和总结语篇中出现的所有衔接机制,包括语篇内部的衔接机制和语篇与语境的关系的衔接机制,还要根据对内容的语用推断建立语篇的语境。最后,把衔接与语境联系起来,共同构建语篇的整体意义。只有这样,才符合人们实际对语篇解码的过程。本项研究将为语篇分析教学和语篇分析研究提供一个新的思路。     

基于篇章的衔接与连贯研究

从篇章的视角来研究衔接和连贯的关系,在篇章而不是话语的框架下先就各自的概念意义等进行分别论述,然后再进行对比分析并得出两者关系的相应结论。篇章是指一段传达完整信息、前后连接、意义一致的自然书面语篇。衔接和连贯是篇章中固有的两种语义关系,都有各自的实现手段,分别在篇章的微观和宏观层次上起着连接篇章成分的作用,相互影响作用,共同赋予篇章以篇章性。
