GeoGebra

The GeoGebra question type plugin allows teachers to set up questions which can be solved and automatically checked using GeoGebra.
This question type also supports randomization of the applet and automatic and manual grading.
With this question type the student has to solve the assignment in GeoGebra. The state of the applet is saved to Moodle for grading or in case it has been possible to automatically grade the assignment for review.
The question type supports randomization of sliders in the applet and substitute variables in the question text with this slider values.
If there are boolean objects present in the applet which indicate the correctness of a solution, those objects can be used for automatically grade the assignment.
