英语语体知识与大学英语教学

大学生入学时英语水平较以往有了提高,这就对大学英语教学提出了新要求,即英语的教和学不能局限于对课本中词句的讲解和篇章的分析,还要了解语体知识,分析各种文体文章的类别和在不同语境中的特点,使学生在实际运用中能够规范得体,从而提高英语综合运用能力。     

三段论格式图的构建与运用

在具体的逻辑推演中,我们不妨从三段论每格所可能具有的有效式着手,构建三段论格式运用图。该图能迅速判定任一三段论式子是否有效,能就三段论的任一项而判定其所有可能式,同时也能从中探讨三段论有效式的组合规律。三段论格式图在实际的教学中也取得了良好的效果,即:既便于学生更直观地理解和掌握三段论的知识,也进一步丰富了形式逻辑的教学内容和方法。     

论言语交际中语境的选择和操控

语境的生成是一个动态的过程,语境生成的动态性不仅体现在言语交际中参与者对相关语境要素的选择和调控上,也体现在言语交际活动之后双方对不同表意框架的选择上.该文通过对一起由手机短信所引发的争议的分析表明:言语交际的参与者为了达到特定的目的,可以对不同语境要素和表意框架进行选择,通过对语境的操控来影响释话人的行为.     

Classroom action research on formative assessment in a context-based chemistry course

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).     

非正式意识形态概念辨析

通过引入“正式意识形态”和“非正式意识形态”概念,以美国为例,试图揭示非正式意识形态的特征、非正式意识形态与正式意识形态的关系,以及非正式意识形态的现实意义。     

系统功能语言学对外语教学的启示

系统功能语法包括“系统语法”和“功能语法”两个部分，但这不是两种语法的简单总和，而是一种完整的语言理论框架的两个不可分割的部分．从韩礼德时语言学和语言的一些基本观点，本文进一步探索贯穿于他的系统功能语法的理论核心。本文主要讨论了系统功能语言学的六个主要思想：纯理功能的思想，系统的思想，层次的思想，功能的思想，近似的或盖然的思想，语境的思想。韩礼德的系统功能语法思想时外语教学具有深刻地的启示意义。本文主要从四个方面来论述这个问题：把外语作为系统来教，语言形式与语言功能在外语教学中并重，在语境教学中进行词汇的文化和语用知识导入。     

批判格莱斯合作原则,探索理解会话含义的新途径

:由于会话含义是隐含于字面意义中的说话者的真实意义 ,缺乏直观性 ,这就为语言的理解 ,特别是跨文化交际中会话含义的理解带来了困难。而格莱斯合作原则只是在微观方面分析了会话含义的产生 ,具有自身的局限性 ,只有结合宏观方面 ,把二者统一起来 ,才能全面地理解会话含义     

语法里的歧义现象

歧义是比较常见的语法现象.最普通的歧义由多义词引起.另外,句子构造层次、语法关系、成分的类型不同,也会造成句法歧义.词汇以外的原因引起的歧义是语境歧义.这三种歧义现象使语言的运用更加丰富多彩.     

Teacher Judgments of Student Reading and Math Skills: Associations With Child- and Classroom-Related Factors

The purpose of the study was to examine whether students’ linguistic skills and task-avoidant behavior (i.e., the child-related factors) and the mean level of academic skills (reading comprehension and math) of classmates (i.e., the class-related factor) are associated with teacher judgments of children’s reading comprehension and math skills. The participants were third-grade Estonian-speaking students (n?=?656; age 9?11 years) and their classroom teachers (n?=?51). The results of the structural equation modeling path analyses indicated that teachers tend to judge students showing higher academic and linguistic skills and lower avoidance behavior as higher on the reading comprehension and math skills. In contrast, the classmates’ higher academic skill level was related to lower judgments of individual children’s reading comprehension and math skills by teachers.     

论认知语境与英语多媒体教学的整合与同构

自上世纪末,我国语言学界掀起了研究认知语言学热潮,尤其是对认知语境与关联理论在对语言教学的指导方面推崇备致,而多媒体在语言教学中的作用却受到了某些人士的质疑。本文的目的在于揭示认知语境和关联理论在指导教学中的局限性,并通过多媒体与传统教学手段进行比照,说明多媒体教学比传统教学更能有效地解决认知语境与关联理论的这一局限性。
