2002年2月,在 K12中国中小学教育教学网的虚拟社区史地政论坛上,一批对历史教学怀有极大热忱的老师自发性地开展起了一个“网上集体备课”行动。2002年9月,活动进一步深入,更名为“历史教师教学网上合作与交流”。为此,陈亚东在《中小学信息技术教育》2002年第5期发表《历史教师网上集体备课的实践和思考》一文,对历史教师网上教研行为指向的特点、虚拟社区论坛支持教研的功能以及相关值得思考的问题进行了论述。本文拟就论坛交流及网上集体备课模式等深层问题进行探讨,旨在为网上教研活动的深入开展、历史教师网上集体备课实践提供理论导向。 In February 2002, at the Virtual Community History and Lands Forum of the K12 China Primary and Secondary Education and Teaching Network, a group of teachers who had great enthusiasm for history teaching voluntarily launched an “online collective preparation lesson”.

The characteristics of the online teaching and research behavior of history teachers, the functions of the virtual community forum in support of teaching and research, and related The issues worth considering are discussed. This article intends to discuss deep issues such as forum exchanges and on-line collective lesson preparation models, aiming to provide a theoretical orientation for the in-depth development of online teaching and research activities and the collective preparation of historical teachers online.
