田径理论课运用个别化教学系统的实验研究

采用组间比较分析、专家评定、问卷调查、数理统计等方法,对田径专项理论课运用个别化教学系统进行了实验研究,并得出如下结论:1)个别化教学系统的教学结构基本特征为:定向掌握,学生自定学习速度,教师少量讲课;使用指导性教材,评估测试。符合以学生为中心,学生自主型向学的原理发展的基本要求。2)个别化教学系统适用于田径专项理论课的教学,并能够较好地掌握田径专项理论知识内容。3)个别化教学系统有利于培养学生的自学习惯和自学能力的发展,为学生向个性化、个别化方向发展提供了空间。

Personalised Indexing and Retrieval of Heterogeneous Structured Documents

In this paper the problem of indexing heterogeneous structured documents and of retrieving semi-structured documents is considered. We propose a flexible paradigm for both indexing such documents and formulating user queries specifying soft constraints on both documents structure and content. At the indexing level we propose a model that achieves flexibility by constructing personalised document representations based on users views of the documents. This is obtained by allowing users to specify their preferences on the documents sections that they estimate to bear the most interesting information, as well as to linguistically quantify the number of sections which determine the global potential interest of the documents. At the query language level, a flexible query language for expressing soft selection conditions on both the documents structure and content is proposed.     

TIJAH: Embracing IR Methods in XML Databases

This paper discusses our participation in INEX (the Initiative for the Evaluation of XML Retrieval) using the TIJAH XML-IR system. TIJAHs system design follows a standard layered database architecture, carefully separating the conceptual, logical and physical levels. At the conceptual level, we classify the INEX XPath-based query expressions into three different query patterns. For each pattern, we present its mapping into a query execution strategy. The logical layer exploits score region algebra (SRA) as the basis for query processing. We discuss the region operators used to select and manipulate XML document components. The logical algebra expressions are mapped into efficient relational algebra expressions over a physical representation of the XML document collection using the pre-post numbering scheme. The paper concludes with an analysis of experiments performed with the INEX test collection.

基于先前知识的说明性文本的阅读教学

说明性文本的阅读理解对英语学习者是一个挑战。通过对阅读本质的认识和说明性文本的特点的分析,本文得出结论认为说明文本阅读理解失败的原因在于先前知识的缺损,特别是有关阅读材料涉及的题材和说明方法知识的缺损,因此,确保阅读理解成功的关键在于建立日趋完善的先前知识体系。对于说明性文本的阅读教学而言,读写结合,选择适当的材料,创造性地运用各种指导方法则是提高教学效果的有效措施。

Technology, math, and the early learner: Models for learning

As today’s preschoolers become the school-age children of tomorrow, early learning educators are faced with a unique and exciting challenge of integrating technology into mathematics instruction. This article examines theory, standards, guidelines, and rationale that supports technology in the preschool environment. Examining practices at 12 diverse preschool sites, four designs emerge as the “typical” models that enable early learners to engage and experience technology within a developmentally appropriate learning environment. The designs outlined are viewed through the lens of preschool mathematics instruction and provide early learning educators as well as parents with models for replication.
