The workload connected with grading open-ended questions is a big challenge, especially in large courses. This incentivizes people to use other question types (such as multiple choice) in their exams. According to the participants of our Survey, the workload is the biggest obstacle to the incorporation of open-ended questions in exams.
This challenge must be addressed if people should be encouraged to use more open-ended questions in their exams. This can partly be achieved through the Digitization of the grading process and, related to this, a well-designed Grading Workflow. In order to reduce the workload of the grading process even further, parts of the grading must be automated (see Semiautomated Grading and Automated Grading).
