网络教学中的信息共享机制研究

在计算机技术和计算机网络的迅猛发展和广泛普及下,教育已不再限于一时一地,正在从传统课堂走向在线施教。网络教学中的信息共享为教学的参与者提供了一种信息的交流传递功能。网络教学系统对信息共享的支持以异步的文件交流和消息传递为主,本文结合教学过程中教师和学生双方的实时交流与协作,分析其共享特性,给出网络教学中信息共享的层次模型,通过实践表明这种层次模型能更好的应对教学过程中的信息获取、信息解析、信息重构以及信息共享的要求。

With the rapid development and popularization of computer technology and network, education is no longer limited to a certain time or place, and is from traditional classroom to online teaching. The information sharing of online teaching provides information communication and passing function for the participators of teaching. The main support of online teaching system to information sharing is asynchronous file communication and message passing. This paper combined real-time communication and collaboration between students and teachers during teaching to analyze the sharing characteristics, present hierarchical model of information sharing during online teaching, and through practice to show that, this model can better deal with information acquisition, analysis, reconstruction and sharing requirements in the process of teaching.
