快速发展的校园网络为指导初中生课外体育锻炼提供了有效途径，但现有的初中校园网中涉及课外体育锻炼指导的内容还不足以满足学生的需求。为了给如何加快课外体育活动指导与校园网络的融合，提高初中生课外体育锻炼的有效性和科学性，增强其参与课外体育活动的积极性等问题提供建议，本文通过文献资料、问卷调查、数理统计、逻辑分析的方法，分析北京市西城区初中校园网站建设情况和当前西城区初中生的课外体育锻炼指导的网络化情况，结论如下：现阶段北京市西城区初中校园网站中已经出现了部分关于课外体育锻炼的栏目，但主要是以校园体育新闻为主，内容相对匮乏，且更新存在滞后性，难以做到全面细致的为学生进行课外体育锻炼指导服务；初中生对利用网络进行课外体育锻炼指导的满意度较高，且对科学的锻炼方法，可供使用的场地、器材，体育项目的教学视频等需求较高。 通过研究分析，本文设计了基于校园网的包括信息发布、技术指导、在线交流、用户管理、资源下载等五个模块的课外体育锻炼指导平台，旨在为校园网络技术有效地用于教学实践及指导初中生自主锻炼提供有效借鉴。

With the campus network developing rapidly, it provides an effective way to guide the extracurricular physical exercise in junior high school. But the present contents of the extracurricular physical exercise guidance in the campus network of junior high school are not substantial enough to meet the needs of students. In order to explore how to promote the integration of extracurricular sports activities and campus network, improve the effectiveness and scientificalness of extracurricular physical exercise, enhance their enthusiasm to participate in extracurricular sports activities, we analyze the network situation in Xicheng District of Beijing and the current Xicheng district extracurricular physical exercise guidance of network situation of junior high school students in the way of literature review, questionnaire, logical analysis and mathematical statistics analysis. There are some information about extracurricular physical exercise in campus website of some junior high schools in Beijing Xicheng district. However, the problems are obvious: the main part of the information is about campus sports news, which means the information is quite limited and simple; it does not update frequently, which results in the difficulty to guide students to do extracurricular physical exercise comprehensively. Besides, generally speaking, students in junior high school are quite satisfied with using campus network to do extracurricular physical exercise, and their high demand of scientific exercise methods, available space, equipment and teaching video can not be ignored as well. This paper designed a platform of extracurricular physical exercise guidance through campus network, based on the following modules: information release, technical guidance, online communication, user management, resource download. The purpose of this paper is to provide an effective reference for the use of campus network technology in teaching practice and students’ autonomous exercise.
