The course element "Topic assignment" is used within an OpenOLAT course. A course author can configure this element as needed and appoint persons responsible for a topic. Further information on how to configure topic assignments can be found in the chapter dealing with the element "Topic assignment". Persons responsible for topics can offer their course participants a variety of topics before managing these participants along with their topics. Course participants will be able to submit expositions via drop boxes. Corrections can then be returned via return boxes.
