【 摘 要 】

In this thesis, I describe uAssign, an assignment system for teaching and assessing command line terminal skills. It allows an instructor to create terminal assignments where students complete a sequence of operations to achieve a goal correctly that can be automatically graded. Assignments can be randomized, and are created to an instructor's specification. uAssign provides a friendly user interface to a Docker container via an in-browser terminal emulator powered by WebSockets. Performance testing and its use in an ongoing course show that it is efficient enough to handle a large number of concurrent users. A survey of students shows significant improvement in terminal skill confidence after using uAssign and provides interesting insight into the preferences and opinions of freshman-level students on the subject of their development workflows and terminal experience.
