图式理论与英语阅读教学:启示与限制

本文从心理语言学和应用语言学的角度出发,分析了图式理论在英语阅读教学中的重要地位,并立足英语阅读教学的特殊性,进一步介绍了如何在教学中激活和建立图示,以及图式理论在英语阅读教学中的局限性.     

E-R图向关系模型转换不一致性的研究

在E-R图向关系模型转换过程中,用转换规则得到的候选码与用候选码定义得到的候选码有时会不一致.本文探讨了转换规则在什么情况下会产生这种不一致的现象,并给出相应的处理措施.     

数学概念图式的加工机制

采用数学测验，对高一、高二、高三420名学生进行了测试，探究学生数学概念图式的加工机制，调查结果表明：（1）不同年级学生的概念图式加工水平存在一定的差异，其中高一组和高三组学生的加工水平的差异性在0．05水平上显著；（2）学生的概念图式在结构和复杂性不同的题目上表现出不同的加工水平，在调查的基础上，提出数学概念图式的“激活扩散”加工模型，这种加工模型体现了更深层次的数学概念加工机制。     

语义图在英语阅读中的运用

在英语教学中构建语义图,是引导学生深入理解文章的一个有效方法。语义图的各层次分别包括学生对相关主题的联想、篇章的背景知识、文章的重点内容等。因此,可以激励学生在课前主动搜索相关知识、积极加入课堂讨论,并在教师的引导下一步步理解文章内容。除了在阅读方面的作用,语义图也是进行听力、口语、写作等方面训练的有效辅助手段。     

Book matters: The effect of Cocky’s Reading Express on student performance

The literature argues that children are more likely to succeed academically if they acquire strong reading skills and a love of reading at a young age. In this paper, I evaluate an early childhood literacy program, Cocky’s Reading Express (CRE), to understand how reading events at school and the gifts of books impact learning. Combining the CRE visit records with administrative student data, I find that CRE leads to 0.02–0.03 of a standard deviation increase in statewide English Language Arts test scores among low-income students one year after the visit and find suggestive evidence that CRE improves the math scores for subgroups of students in poverty. In particular, the CRE effect varies based on locality and access to reading materials, with a larger effect on students residing in metropolitan areas or close to public libraries. However, the positive effects on low-income students diminish over time; CRE does not show impacts on the scores of students from better-off families either.     

Specifying Hotel Guestroom Reservation ystem Using Z Notation

The use of formal specification in software development is becoming increasingly prevalent. The Z nota-tion is a formal method, a language, and a style for expressing formal specification of software systems. This paperpresents a part of the specification work on a hotel guestroom reservation system.

英文阅读图示、空缺与图示建构

从心理语言学的角度分析,阅读理解的成败在很大程度上取决于读者对阅读材料主题的先期了解——即“图示”。如果阅读过程中图示出现空缺,理解就会遇到障碍;填补空缺,阅读活动便可顺利完成。语言图示空缺与自下而上阅读模式中语言认知能力有关;内容图示则影响到自上而下阅读模式中读者预测、验证和把握阅读材料的主题理解,涉及语言本体意义之外的知识。     

面向企业业务的智能知识推送研究

企业在生产过程中会不断产生新的知识,但用户却不能及时地了解这些新知识的存在,为了提高知识主动服务的能力,提出了构建面向企业业务的知识推送系统。首先阐述了企业业务活动与知识的关系,然后提出了一种面向企业业务的智能知识推送系统模型,并对其实现的关键技术作了进一步的阐述。该模型为构建面向企业业务的知识推送系统以及解决系统构建中的关键问题提供了理论指导。

Abstract：

New knowledge is continuously generated in enterprise production process,however,users can not know the existence of new knowledge in time.In order to improve the active service capacity of knowledge,this paper proposes to build a knowledge push system for enterprise business.The paper firstly expounds the relationships between enterprise business activities and knowledge,then proposes a model of the intelligent knowledge push system for enterprise business.The key technologies for the construction of the system are also elaborated.The model provides theoretical guidance for building the knowledge push system for enterprise business and for solving the key technologies in the construction of the system.
