一般来说,为了防止计算机中毒后影响教学,学校微机房的学生用机大都安装了类似“还原精灵”这样的系统还原软件。教师在授课的过程中可能会利用多媒体教室软件分发教程、作业文件。由此带来一个问题:学生在完成作业的过程中一旦计算机死机重启,那么正在完成的作业和教师分发的文件都会丢失,教师要重新分发文件,学生也要重新完成作业,这就给教师和学生增加了额外的负担,而且学生完成的作业在上传后不便很好的管理和长期保存。这样势必会影响到教学的效果,构建这个系统的目的之一就是解决以上问题。
In general, in order to prevent the impact of computer poisoning teaching, students in the school computer room mostly installed a similar “Restore Wizard ” system restore software. Teachers may use multimedia classroom software to distribute tutorials and homework documents during lecture. This poses a problem: students complete the homework in the process of restarting the computer crashes, then the finished homework and teachers distributed files will be lost, the teacher should redistribute the files, students have to complete the homework, which gives teachers and Students add an extra burden and students’ finished assignments are not well managed and stored long after uploading. This will inevitably affect the effectiveness of teaching, one of the purposes of building this system is to solve the above problems.
