DDTA Quiz for Moodle

The "DDTA Quiz" (Digital Diagnostive Test Assignment) activity is a plugin for the open-source learning platform Moodle. Like the standard "Quiz" activity, a teacher can create a test for students to take. The test also consists of a number of questions, but in contrast to the standard quiz it is possible to show questions depending on the performance of the student in previous questions.

Purpose

The conditional display of certain questions allows a multitude of scenarios. The main motivation for the development of this plugin is to have a possibility to detect the cause of student errors on a fine grained level.

For example a student might be asked to find the local extremum of a parabola. If the question is answered correctly, the student shall just proceed with the test. If it is answered incorrectly however, there will be extra questions to detect the cause of the incorrect answer. In this scenarion this will most likely be a task to find the derivative of the parabola's function and to find the root of it.
