国内高校图书馆管理集成系统的选择

本文在对我国高等学校图书馆管理集成系统使用情况分析的基础上，简要介绍了几种拥有用户较多的文献信息管理系统，并据此提出高校图书馆在选择文献信息管理系统时应注重的标准、原则，指出高校图书馆管理集成系统的发展趋势。     

Two-stage statistical language models for text database selection

As the number and diversity of distributed Web databases on the Internet exponentially increase, it is difficult for user to know which databases are appropriate to search. Given database language models that describe the content of each database, database selection services can provide assistance in locating databases relevant to the information needs of users. In this paper, we propose a database selection approach based on statistical language modeling. The basic idea behind the approach is that, for databases that are categorized into a topic hierarchy, individual language models are estimated at different search stages, and then the databases are ranked by the similarity to the query according to the estimated language model. Two-stage smoothed language models are presented to circumvent inaccuracy due to word sparseness. Experimental results demonstrate that such a language modeling approach is competitive with current state-of-the-art database selection approaches.     

基于支持向量机的文本自动分类试验研究

提出了将支持向量机应用于文本自动分类的研究，与常用的K-最邻近法相比，无论是对训练数据集还是测试数据集均具有一定的优势，而且不同特征选择方法对支持向量机的影响要比K-最邻近法小。此外，从研究中的不同特征选择的评价函数来看，它们对分类有一定的影响，应用X2统计进行特征选择的分类正确率最高，其次是文本证据权，而期望交叉熵的效果最差，说明特征选择在文本自动分类中也是相当重要的。     

Setting the Students’ Bearings and Balance in Appraisal

The author, a professor at the University of Toronto, touches briefly on the extensive and rich archival literature that supports the teaching of macroappraisal, but notes that this is not the only educational material she offers her students when teaching appraisal theory. She discusses the usefulness to archivists of literature from the fields of ethnography, organizational knowing, records in history, personal documentary behaviour, memory, and communications, noting that the use of texts from these fields can encourage students to reflect on their own presumptions and to develop a taste for the wide reading and research that must support appraisal.     

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。     

基于OBE理念,构建通识教育课程教学与评估体系——以清华大学为例

国内高校积极探索实现通识教育的路径已有多年,但其效果在一定程度上仍然受到质疑。课程是实现通识教育的主要载体,清华大学在探索构建通识教育课程体系过程中,尝试性地采用了工科教育中广泛使用的成效基准教育理念与能力导向课程设计来分析当前我国大学通识教育的课程建设,指出通识教育众课程与通识教育目标之间欠缺逻辑对应的普遍性问题。本文重点介绍了清华大学通识教育课程建设中的困惑和设想,探讨了如何锚定与对应课程与能力目标之间的逻辑关系。本文建议高校在通识教育初建阶段将引入OBE框架以及能力导向课程设计理念可作为一种选择,此举有助于厘清大学通识教育在本科教育中的定位与通识课程之间的逻辑和结构关系。     

新课改背景下教师权威的消解与重构

随着新课程改革的不断推进，教师权威受到严峻的挑战。教师权威的存在是客观且有其合理性的。新课程消解了教师的知识权威、传统权威和法定权威。重建教师权威，需要从转换教师角色、改善知能结构、完善人格等几个方面着手。     

Suggestions for the "Integration in Multiple Certificates" Curriculum System Construction

Business English professional "Integration in Multiple Certificates" refers to these two kinds of certificates——a diploma and vocational certificates. Business English curriculum design unified vocational qualification certificate with professional training objectives. Basis on the meeting of requirements of certificates for graduation, making professional training contents, curriculum,teaching methods together with vocational training and the requirements of professional qualification certificates.     

Finding the common ground: Teachers' and employers' representations of English in an assessment context

There has been a long‐standing debate about how ‘English’ can be defined. Educational policy changes have typically been driven by differing representations of the subject, and have ranged from broad ‘aesthetic’ definitions to more narrow ‘functional’ views. The present study aims to analyse areas of consensus and contention in stakeholders' discourse regarding English. A questionnaire‐based survey and focus groups were used to explore how teachers and employers viewed English as a subject. Their views were conceptualised into three themes: the importance of functional English; English as atomistic versus holistic study; and English as critical thought. These themes are discussed in relation to historical definitions of ‘English’, and their implications for the future reform of English qualifications.     

Six into One: The Contradictory Art School Curriculum and how it Came About

This article reports historical research which sought to understand the present‐day post‐secondary art curriculum through analysing its history in terms of changes in conceptions of art. It found that there have been six distinctive curricula: Apprentice, Academic, Formalist, Expressive, Conceptual and Professional. As a new curriculum has been introduced, it has co‐existed with much contained in a previous one. Most of the curriculum changes have taken place in the past 65 years. During this time, there has been a massive expansion in the education of artists and at the same time art schools accommodated first modernism and then post‐Duchampian aesthetics. A conclusion is that this has made for a very crowded curriculum. Moreover, despite there being an ever increasing choice of things a student might learn, it appears that there is nothing which all students have to learn. It can be problematic that one part of the curriculum is in contradiction to another part, and moreover this lack of a core raises fundamental, ontological questions about what art as a discipline is.
