远程虚拟微格教学系统的构建

Constituting Long─range Virtual Micro─teaching System

微格教学是对教师职业职前与职后技能培训的有效方法。为了优化微格教学系统，扩大其应用范围，提出了基于Web 2．0与Web 3D，并融合3D网络虚拟环境（NVE）和虚拟交互社区（VIC）概念的远程虚拟微格教学系充架构的可行方案。着重对系统的逻辑结构、主要功能、网络架构及相关协议，以及硬件需求进行了分析与探讨。

Micro─teaching is an effective way for the training of teachers both before serving and after serving. The article puts forward the feasible way of constituting long─range virtual micro─teaching system based on the Web 2．0 and Web 3D， combined with the concept of 3D network virtual environment（NVE）and virtual interactive system（VIC）， the new constituting is to optimize the former micro─teaching system and to widen its using content. The logic frame of the system， the main function， the network architecture， the related agreement and the hardware requirements are also analyzed and discussed.
