学生上课时总有这样那样的原因，偶尔有一次课因为时间冲突不能上课，为了让临时缺课学生赶上上课进度，这里介绍一下如何给学生录制视频并开启相应权限：

1.如果用ZOOM给学生上课的话，共享桌面后点一下共享桌面控制台的 More->Record按钮，Zoom就会开始录制视频，请检查Zoom的系统配置获得视频文件的存放路径：

2.上课完毕关闭ZOOM,ZOOM会将视频文件压缩成MP4文件，稍等一些时间，等MP4文件就绪后，通过网课后台系统"课程列表"找到对应课程，勾选课程并选择视频文件上传，上传过程需要看浏览器左下方的进度条，上传成功后请在"视频文件"列"Open It!"打开播放一下，确认无误后再进入下一步讲视频分享给指定学生：

3.通过后台系统菜单"培训班作业"，找到需要分享视频的指定学生作业，将视频文件的权限给缺课学生打开。请注意：目前的规则是如果学生缺课并要求录制视频，

需要给学生照扣课时(布置作业时为该学生选择"布置作业并扣课时"按钮)；否则不要求录视频则算请假，布置作业时不扣课时(布置作业时为该学生选择"只布置作业不扣课时"按钮)。

4.视频上传和分享完毕。

谢谢你的视频录制、上传和分享工作让缺课学生仍然保持统一的学习进度！

对于像COMC、FRYER、GALIOS、EUCLID需要写步骤的数学竞赛，为了让学生在竞赛中取得好成绩，老师往往需要给学生在做题步骤上做一些指点。

目前我们的后台教学系统已经完全支持这一功能，这里详细列出了使用步骤：

In order to make the students have the best performance in the contest like COMC、FRYER、GALIOS、EUCLID,which require the students to write solution steps, the teachers need to grade the homework and send out the comments and score。

Now this functionality is already provided by our backend system,here are the detailed steps:

1.Click 培训班管理->培训班作业, Choose the student's homework you want to score and click "答卷"：

2.Here you will see all the answers of this practice from the student,click "批改作业" in the row of that question which you want to score:

3.Here you can write anything for the comment of this question in the same way you do the handwriting in the class:
