构建知识地图——论现代目录学理论的发展与创新

20世纪90年代以来目录学发展的社会环境发生了根本性的变化，技术化（自动化、数字化、网络化、虚拟化）和知识化（精确化、个性化、综合化、多样化）是新时期目录学发展过程中两大最明显的特征。目录的本质是知识地图，目录工作的使命是绘制和构建知识地图，目录学是研究知识地图绘制、构建和利用理论与方法的一门学科。用“知识地图学”来替代目录学，是传统目录学的新生。

Collaborative Approaches to the Management of Geospatial Data Collections in Canadian Academic Libraries: A Historical Case Study

The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own.     

微课在民族地区的应用探究

民族地区地理环境恶劣、经济条件差等造成教育存在诸多问题,唯有发展远程教育才能尽量缩小因地域问题带来的教育差距和缩短因教育资源不均衡带来的影响,而微课依托于网络,短小精悍、资源多样,能够解决目前民族地区教育面临的一些问题。为了避免教师、学生的个人单一行为,造成时间、精力的浪费;统一、有序的开发微课也就势在必行,而这需要州教委组织全州教师按照知识地图,划分科目知识点,布置任务,做到资源共享。     

构建思维导图模式促进地理教学的效果分析

二十世纪初,随着我国教学课程教学改革的进行,全新的课程理念和教学目标对各科目的教学提出了更高的要求,打破了传统的以传授讲解知识为目的的教学模式,更加注重对学生主观能动性的发挥和提高主体意识的建设。思维导图作为一种全新的思维策略方式,通过在地理教学过程中加强对其恰当的应用可以有效地促进新时期地理的教学效果。     

Digital body preservation: Technique and applications

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.

新课程视野下的语文基础知识探析

基于新课程视野的语文基础知识是指学习语言文字运用所需要的基础知识。根据现代认知心理学分类理论和中小学语文教学实际,认为语文基础知识由事实性知识、概念性知识和程序性知识构成,三个层面构成的语文基础知识体系就像一座"宝塔",据此来来审视当前的语文基础知识状况,从而提出教学方法的选择必须以知识的分类为基础,选择积累法、感悟法、案例法和训练法。
