On improving automated self-assessment with moodle quizzes: Experiences from a cryptography course

Although Moodle quizzes are a wide used tool for e-assessment, they present some limitations regarding the possibility to provide randomized quizzes with different questions for each different student. In this paper, we present different approaches to incorporate variables with randomness in questions within Moodle, so that multiple versions of the same question can be generated automatically reducing the workload of the teacher when preparing the quizzes. Furthermore, we explain our experiences in the design and deployment of self-assessed questions, with randomness and feedback, to an online Cryptography course.
