CCLI-EMD: Topic Maps-based Courseware to Support Undergraduate Computer Science Courses

计算机科学(31)这个项目使用新的ISO标准来组织、检索和交换Web上的语义信息，主题地图，用于开发计算机科学的电子学习课件。具体地说，该项目正在为本科计算机科学课程的四个模块开发主题本体，使用它们来创建基于主题地图的综合学习材料，并在网络辅助课程中利用开发的材料来评估它们对学生学习的影响。该项目正在证明，基于概念的组织是构建STEM学科特别是计算机科学中数字学习内容的一种有效形式，并证明主题地图技术适合于在Web上开发高效的可搜索和可重复使用的教育材料。主题地图编辑器和查看器可通过NSDL获得，该项目正在为想要开发自己的主题地图软件的人开发研讨会。该项目的智力优势在于基于概念的教育材料组织，通过支持主题感知内容浏览和基于上下文的信息检索，为改善学生在STEM学科中的学习提供依据。开发的基于主题地图的计算机科学模块将作为本体驱动的课程的模型。该项目对课件开发人员的更广泛影响来自于促进本体在电子学习中的应用和使用新的主题地图标准，以及通过开发提供自我探索和任务相关信息搜索指导的课件，特别是对概念理解和推理困难的学生。

Computer Science (31)This project uses the new ISO standard for organizing, retrieving, and interchanging semantic information on the Web, Topic Maps, for developing e-learning courseware in computer science. Specifically, the project is developing subject ontologies for four modules of undergraduate Computer Science courses, using them to create comprehensive Topic Maps-based learning materials, and utilizing the developed materials in Web-assisted courses to assess their impact on student learning. The project is proving that a concept-based organization is an efficient form of structuring digital learning content in STEM disciplines and especially in Computer Science, as well as proving that Topic Maps technology is suitable for developing efficiently searchable and reusable educational materials on the Web. The topic map editor and viewer are available through the NSDL and the project is developing workshops for persons who want to develop their own topic-map based software.The project's intellectual merit lies in concept-based organization of educational materials, providing grounds for improving students' learning in STEM disciplines by supporting topic-aware content browsing and context-based information retrieval. The developed Topic Maps-based Computer Science modules will serve as a model of ontology-driven courseware.The project's broader impacts on courseware developers comes from promoting the application of ontologies for e-learning and using the new Topic Maps standard, and on learners, by developing courseware that provides guidance in self-exploration and task-related information search, especially for students with difficulties in conceptual understanding and reasoning.
