How an understanding of Bakhtin's theory of the chronotope can assist progression in classroom writing

Our argument in this paper is that the model of literary progression which Bakhtin (1981, 1986) expounds in his writing on the chronotope can generate insight into the processes through which pupils improve their writing. We suggest more generally that there are concepts and clues in Bakhtin's historical model of the development of the European novel and in his theory of dialogue which can be helpful in both the evaluation and teaching of classroom writing.     

S变换与小波变换检测信号突变性研究

时间局部谱分析方法的研究对信号突变性检测具有重要意义。S变换是加窗傅里叶变换和连续小波变换思想的延伸或推广,S变换保持了与傅里叶谱的直接联系,提供了依赖于频率的分辨率,具有连续小波变换所没有的一些特点。介绍了S变换和广义S变换的数学原理,分析了S变换与加窗傅里叶变换和小波变换之间的关系,对一个突变信号在S变换与小波变换下的表现特征进行研究,结果表明,S变换能比小波变换更直观更清楚地表现信号突变位置。     

与学习进阶相适宜的科学探究课程方案述评

美国的科学探究课程IQWST提供了把科学探究学习进阶理论转化到教学实践的有效方式。其开发理念为:依据学习进阶框架确定课程目标,以"驱动问题"为线索设计、组织课程内容,强调科学知识和科学实践能力共同进阶。这启发我们在落实以"核心素养"为目标的课程改革中要注重知识的部分与整体的联系,课程中合理设置科学实践活动,做好科学探究课程与传统课程的结合。     

Does working during higher education affect students’ academic progression?

This paper examines the effect of working during higher education on academic progression, in terms of number of credits acquired by first-year university students in Italy. We discuss different contrasting hypotheses on the role of employment during university on academic outcomes: the zero-sum perspective, the reconciliation thesis, the positive and the negative selection to work hypotheses. In the empirical part we analyze data from the Eurostudent survey, which collected data on a representative sample of university students who were enrolled in the academic year 2002/03, after the implementation of the ‘Bologna Process’. We use a negative binomial regression model considering work experience as an endogenous multinomial treatment. Results indicate that, conditional on observed covariates (socio-demographic variables, school-related and university-related variables), there is a positive self-selection into employment, especially for low-intensity work. Traditional multivariate regressions show a penalty in academic progression only for high-intensity workers, but once accounted for unobserved heterogeneity also the low-intensity work experience appears to negatively affect academic progression.     

语篇的主谓推进模式分析

主位推进模式理论是分析篇章段落中连续分句中主位、述位之间关系的一种理论,是分析篇章微观结构的重要手段.Halliday将信息结构与主述位结构分离的观点以及Danes的主位述位出现顺序决定语篇信息结构的观点为进一步划分主位推进模式提供了理论基础.通过了接主位推进模式,可以帮助作者们更好的构建篇章的整体框架.因此主述位推进理论对英语的写作、阅读等教学工作有重要的指导意义.     

Translation Analysis from Functional Linguistics Perspective

As a branch of linguistics,Functional Grammar plays an important role in translation analysis.From the perspective of patterns of progression and cohesion,a text and its translation from TEM8 examination is studied as an example to get some general rules,and thus,a new approach of translation analysis is offered.

初学者英语语音意识培养之浅谈

语音意识与阅读理解,单词拼写及记忆等方面有着极为密切的联系。利用语音意识进行语言学习已成为普遍认同的理论。该文在简单回顾了国内外语音意识发展的历史后,详细阐述了语音意识测试的步骤及方法,指出只有在对英语学习者语音意识进行有效的评估后,才能对症下药,培养他们的语音意识;同时指出语音意识的发展是一个渐进式发展的过程,英语教育教学工作者只有根据其规律,灵活施教,才能起到事倍功半的效果。     

主位推进模式对大学英语写作教学的启示——以一次当堂作文练习为例

由于传统的英语写作教学过分注重语法和句子结构,学生能够写出合乎语法的正确句子,却不知如何布局谋篇,如何处理句子与段落、段落与篇章的关系。该文运用主位推进模式分析非英语专业学生的一次当堂四级水平要求的英语作文,着重从语篇层面分析学生的弱点,探讨该理论在大学英语写作教学中的应用。     

主位推进模式在大学英语写作教学中的应用

衔接与连贯是学生在英语写作中存在的问题。功能语言学的主位推进模式为大学英语写作教学中的衔接与连贯问题提供了新的启发。因此,本文将在系统功能语言学的主位推进模式理论的指导下,对大学英语写作教学进行研究,以期提高学生的语篇组织能力,从而提高学生的写作水平。
