本教学互动网站系统由三个模块组成。学生模块，教师模块以及管理员模块。网络教学管理系统规定了管理员、教师、学生的可以进行的操作，管理员、教师通过后台来对教学资源等进行管理，教师和学生登陆后在各自的空间进行教学和学习。因此，平台可分为两条主线：教师和学生。

（1）教师

教师用户登录成功后，进入教师用户界面，他可以对自己所授课程进行管理，发

布课程公告，发布课件、教案，参与讨论区，管理个人信息等。

（2）学生

学生用户登录后，进入学生用户界面。学生用户拥有的功能包括：课程学习、讨

论区、在线考试、完成作业等。

学生模块：

学生端主要包括的功能有：系统说明、个人信息、修改密码、信息公告、网络课堂、成绩查询、作业提交、在线交流、上机考试、自测练习、讲义资料、答疑论坛等功能。

管理员模块：

管理员端主要包括的功能有：系统说明、添加学生、修改教师、添加公告、考试

管理、新闻列表、论坛管理等功能。

教师模块：

教师端主要包括的功能有：作业管理、课程通知、课程答疑、信息公告、课程讲义、成绩管理功能等。
