【摘要】 网络电视作为一种新型现代媒体,以其操作便捷、内容丰富及互动交流等优势,成为现代教育教学新的学习方式.当前E-Learning系统普遍存在内容结构单一、教学资源凌乱、重用性与共享率不高、个性化学习需求难以满足等问题.本研究从网络电视与精品课程资源的整合应用、精品课程知识点虚拟切片、切片检索学习模式以及切片检索学习过程中知识点获取、学习习惯及交互环境等多角度构建了面向知识管理的网络电视切片检索学习系统,实现了低成本、支持IPv4/IPv6协议高标清网络电视系统虚拟切片学习平台,并利用这一平台从知识管理的视角分析了精品课程知识点虚拟切片检索学习与传统教育模式的异同.该研究为构建完善的网络电视切片检索学习模式与精品课程资源整合应用提供良好技术支持与平台服务.更多还原

【Abstract】 Network television as a new type of modern media,with its convenience in operation,abundance in content,and the advantages of the interactive environment,is becoming a new approach to learning modern education teaching.The current E-Learning system has universal problems such as the simplification of content and structure,disorders of teaching resources and low reusing and sharing of teaching resources,lack of personalized learning and education,and so on.The present study constructs knowledge management-oriented virtual slice learning model of network television education system including the integration application of network television and excellent curriculum resources,virtual slice of key knowledge point in high-quality courses,application model and knowledge resource acquisition in slice retrieval,study habits,interactive environment,etc.and realizes digital virtual slice learning platform of a low-cost HD and SD network television system supporting IPv4/IPv6 protocol.The similarities and differences about how to manage knowledge between the virtual slice retrieval learning of excellent courses knowledge and traditional educational model are investigated by this platform.This study provides a good technical support and platform services not only for constructing virtual slice retrieval learning mode of network TV system,but also for intergration and application of high-quality courses.更多还原
