防止实验室操作中的作弊
Preventing Cheating in Hands-on Lab Assignments
摘要：
网络、操作系统和网络安全技能在真实的环境中得到最好的锻炼。学生在实验室环境中使用真实的系统和工具，并完成指定的任务。由于所有学生通常都会收到相同的作业，因此他们可以向教师，辅导系统或同龄人咨询他们的方法和进度。他们也可以在互联网上搜索信息。在课堂上为所有学生布置相同的作业是有效学习和发展技能的标准做法。然而，当在诸如评分作业、期中考试或期末考试等总结性评估中使用时，它很容易作弊。学生可以很容易地在没有完成作业的情况下共享并提交正确答案。在本文中，我们讨论的方法自动生成的动手在计算机实验室环境中完成的任务的问题。使用这种方法，每个学生都收到个性化的任务。我们开发了用于生成和提交这些个性化任务的软件，并进行了案例研究。该软件被用于为207名学生注册的安全入门课程的家庭作业创建和评分。该软件发现了七个可疑的提交案例，这些案例可能构成作弊。此外，学生和教师欢迎个性化的任务。教师评论说，这种方法适用于大班。学生在运行个性化实验室环境时很少遇到问题。最后，我们发布了开源软件，使其他教育工作者能够在他们的课程和学习环境中使用它。
英文摘要：
Networking, operating systems, and cybersecurity skills are exercised best in an authentic environment. Students work with real systems and tools in a lab environment and complete assigned tasks. Since all students typically receive the same assignment, they can consult their approach and progress with an instructor, a tutoring system, or their peers. They may also search for information on the Internet. Having the same assignment for all students in class is standard practice efficient for learning and developing skills. However, it is prone to cheating when used in a summative assessment such as graded homework, a mid-term test, or a final exam. Students can easily share and submit correct answers without completing the assignment. In this paper, we discuss methods for automatic problem generation for hands-on tasks completed in a computer lab environment. Using this approach, each student receives personalized tasks. We developed software for generating and submitting these personalized tasks and conducted a case study. The software was used for creating and grading a homework assignment in an introductory security course enrolled by 207 students. The software revealed seven cases of suspicious submissions, which may constitute cheating. In addition, students and instructors welcomed the personalized assignments. Instructors commented that this approach scales well for large classes. Students rarely encountered issues while running their personalized lab environment. Finally, we have released the open-source software to enable other educators to use it in their courses and learning environments.
