昨天晚上，和博士生同学一起期末总结。
Last night, the final wrap-up was with the doctoral students.
目前在香港一所高校任教的大海同学，介绍了自己这一个学期对开源软件的研究，从Moodle，到 WordPress，再到Ubuntu，他对开放源代码、开源软件、以及开源软件的教育应用，有了更加深刻的理解和认识。
The students who are currently teaching open-source software at a high school in Hong Kong, from Moodle to WordPress to Ubuntu, have a better understanding and understanding of open-source, open-source software and open-source software educational applications.
在他汇报的过程中，他提到了他们大学，为了应对疫情，采取SEB进行在线期末考试，这使得我想起来前些日子，在给家乡的教师同仁在线公益分享的时候，不少教师提到学生居家学校在线考试的问题。
In the course of his reporting, he referred to their universities and, in response to the epidemic, the use of SEB for the online final examination, which reminded me of the fact that a number of teachers mentioned the issue of the online examination at home school when they shared online public goods with their teachers in their home countries.
后来，我还专门撰写了一篇题为《抗击疫情：学校如何在线考试》的推文。
Later, I also wrote a special article entitled ".
结合大海这个汇报，我就去检索有关SEB的信息，发现这个SEB还真是可以解决分布式在线考试的一些现实需求。
In conjunction with the ocean report, I went to retrieve information about the SEB and found that the SEB was a real solution to some of the real needs of the distributed online examination.
安全考试浏览器（Safe Exam Browser，SEB） 是一款定制的、开放源代码的 Web 浏览器，可用于 Windows（7、8.1、10）、macOS（从 10.7 开始，推荐使用 10.11 或更高版本）和 iOS（9.3.5 或更高版本）。
Safe Examination Browser (Safe Exam Brownser, SEB) a custom-made, open source browser that can be used in Windows (7, 8.1, 10), macos (from 10.7, recommended version 10.11 or higher) and iOS (9.3.5 or higher).
目前，在 Android 上，SEB不可用。
Currently, on Android, SEB is not available.
这个安全考试浏览器应用程序必须下载，并安装在居家学习，要参加在线考试的学生的设备上。
The security examination browser application must be downloaded and installed on the equipment of students attending the online examination, who are studying at home.
学生居家学习，学校在线考试，面临很多难题，其中之一就是监考。
Students study at home, and school online examinations face many difficulties, one of which is the supervision of examinations.
尽管教师和家长可以在学生居家考试的地方，通过两个摄像头，使得学生及其电脑公开，但是监考的教师要快速浏览那么多摄像头画面，也是比较困难的。
Although teachers and parents can use two cameras to make students and their computers public in places where students are tested at home, it is also difficult for teachers in supervisory examinations to quickly view so many cameras.
在参加考试的时候，一些学生可能会利用在线接住介入网络的电脑，连接到互联网，以获取有助于他们获得更高分数的试题相关的信息。这不仅会使得在线考试无效，而且还会影响学生的学术诚信。
At the time of the examination, some students may use online access to network computers to connect to the Internet in order to obtain information that will help them gain a higher score. This will not only render online examinations ineffective, but will also affect students’ academic integrity.
安全考试浏览器 (SEB) 可以帮助避免此问题，因为它可以通过浏览器操作控制，来控制 Internet 接入和对特定应用程序的访问。
The Security Examination Browser (SEB) can help to avoid this problem because it can control Internet access and access to specific applications through browser-operated controls.
教师可以将安全考试浏览器配置为针对每项考试采取不同的行为。
Teachers can configure safety examination browsers for different behaviors for each examination.
当学生进入他们的在线考试的时候：
When students enter their online exams:
浏览器窗口将没有 URL 或搜索字段；
The browser window will not have a URL or search field;
教师可以设置禁用后退/前进导航和重新加载；
Teachers can disable backward/future navigation and reload; & nbsp;
在提交在线考试答卷之前，学生无法关闭安全考试浏览器。
The student cannot close the security examination browser before submitting an online examination response. & nbsp;
Win+Tab、Alt+Tab、Ctrl+Alt+Del、Alt+F4、Print Screen、Cmd+Tab 等快捷键被禁用，或不能用于关闭 Safe Exam Browser ，或切换到计算机上的其他用户帐户。
Win+Tab, Alt+Tab, Ctrl+Alt+Del, Alt+F4, Prince Screen, Cmd+Tab etc. are disabled or cannot be used to close Safe Exam Browser or to switch to another user account on the computer. & nbsp;
安装了SEB浏览器的电脑截屏的功能被禁用。

使用 URL 过滤器将特定网站/页面/资源配置为在考试期间可访问。

拼写检查和字典查找可以设置为禁用或允许。

默认情况下，禁用切换到其他应用程序，可以通过使用配置工具，创建自定义配置文件，以允许访问相关应用程序。
By default, disables switching to other applications and can create custom configuration files by using configuration tools to allow access to related applications.
比如，通过设置允许学生使用 Word 或 Excel 等应用程序。
For example, students are allowed to use applications such as Word or Excel through settings.
世界上不存在百分百安全的东西。
There is no 100 per cent security in the world.
在传统的教室里，即便是安排5位监考老师，恐怕也没有人敢保证百分百无人作弊。
In the traditional classroom, there is no guarantee of 100 per cent fraud, even with the placement of five supervisory teachers.
安全只是相对的，绝对的安全几乎是不存在的。
Security is only relative, and absolute security is almost non-existent.
是的！安全考试浏览器是开放源代码软件，它是免费的。
Yes, the security exam browser is open source software, it's free.
