25 25  Die Post-Variablen werden nach Beantwortung, Abgabe und automatischer Bewertung der Einzelaufgaben belegt und ermöglichen somit Zugriff auf antwortspezifische Werte wie die Lernerantwort oder Punkteinformationen. Die generierten Werte können für Folgeaufgaben verwendet werden.

94 94  Definieren Sie Testvariablen, welche nach Abgabe jeder Einzelaufgabe neu berechnet werden (kurz: Post-Variablen). In die Werteberechnung können während der Testbearbeitung ermittelte Werte wie die Teilnehmerantwort, erreichte Punkte oder genutzte Lösungsversuche einbezogen werden. Dies ermöglicht beispielsweise Punkte- oder Fehlerzähler und aufbauend die Steuerung von nachfolgenden Aufgaben, Hinweisen oder Feedbackinhalten.

125 125  Specifically, the following scenarios are feasible:
126 126  
127 -* Related question complexes can be parameterised by common, global variables (test variables). The random values allow for different question values in each test attempt and for each participant.
128 -* Learner answers, performance and identified "typical" or systematic mistakes made by the learners can be stored and taken into account for later questions.
129 -* More detailed information on the users’ performance as regards the individual questions can be generated during the test and collected as the basis for a personalised overall assessment (test feedback).
130 -* Initially, participants can configure specific settings (e. g. for the difficulty level and thematic focus) themselves, which will then be stored in global variables and affect subsequent questions.

The generated values can also be used for follow-up questions.
