8 8  Post-variables are only assigned after the task has been answered, submitted, and automatically assessed, thus allowing access to response-specific values such as the learner's response or the points for correct answers. In this way, adaptive feedback content, follow-up tests, and task series can be enabled. The use of conditions and MAXIMA statements allows responses from learners to be analysed and typical errors identified. Based on these insights, teachers will then be able to provide appropriate feedback or customised exercises.

47 47  Define variables that are determined after the submission of the task in order to create adaptive task and test scenarios. Post-processed variables (in short: post-variables) allow you to access the learners' answers and points achieved. You can use this information to enhance following content such as feedback or task descriptions of follow-up attempts. In addition, it is possible to intervene in the assessment and make subsequent changes to it.
