Development of a Quiz – Implementation of a (Self-) Assessment Tool and its Integration in Moodle

Technology Enhanced Learning has become more popular in recent times and many organizations and universities use it as a key instrument in various teaching and training scenarios. At the University of Technology of Graz, some courses require randomized quizzes where question variables can be assigned by arbitrary mathematical functions and this feature is missing in the current solutions. This article describes the development of a quiz application that can be integrated into Moodle by utilization of the Learning Tools Interoperability protocol (LTI). The PHP application is built to support programmable questions that can contain JavaScript and HTML code. Teachers are able to build interactive, randomized quizzes, in which the random variables can be assigned with complex mathematical functions. Furthermore, the application provides a programmable grading mechanism. With this mechanism, it is possible for students to self-assess their performance, as well as for teachers to formally assess their students' learning success automatically and send the results back to Moodle (or other LTI compatible consumer applications).
