网络化多媒体数据库的教育应用

Educational Use of Networked Multimedia Databases

作为学习环境的网络化多媒体数据库的教育功能取决于现有的内密(学科)、内容的表现形式(涉及所有的媒体)、内容的组织(涉及信息结构)、内容的存取和呈现方法(恢复机制、视频和音凝的呈现形式)、管理与用户的互动(用户行为的登录和进程控制的机制)、和通讯工具(e-mail、ftp等)。网络化多媒体学习环境可被分解为三个部分,通常是:数据库、数据库工具和会话工具;其在教育上的应用主要是个体学习环境.网络小组学习环境.基于班级的教与学的环境和混合环境四种。我们希望,教学设计范式或模型在与技术发展的互动中将产生更多更好的学习环境。

The functionality of networked multimedia databases as learning environments is determined by available content, the representation of that content, the organization of that content, the way in which the content can be accessed and presented, the management of the interaction with the user, and communication facilities. Networked multimedia learning environments can be devised into three components: database, database tools, and conversational tools. The educational use of these environments includes Individual Learning Settings, Networked Group Learning Settings, Classroom-Based Teaching and Learning Settings, and Hybrid Settings. The interaction between instructional design paradigms and technology will give us learning environments more and better.
