Hendrik Zschocke 111.1 4 Adaptive feedback allows for individual feedback based on the learners' answers. The participant can, for example, be provided with concrete hints or error messages. Post-variables ([[post-processed variables>>doc:ONYX.Erstellung von Testinhalten.Aufgaben.Variablen verwenden.WebHome]]) give access to the learners' responses, e. g. to each gap. Attempts at solutions or even previous answers can also be included in the feedback.In the following, the [[Example "Transport" - Use of random parameters>>doc:ONYX.Erstellung von Testinhalten.Aufgaben.Variablen verwenden.Beispiele zum Einsatz von Variablen.Beispiel Transport - Einsatz von Zufallsparametern.WebHome||shape="rect"]] will be extended by simple adaptive feedback. Feedback should give the user an indication of whether their answer was less than or greater than the correct solution or hint at how the correct solution can be calculated.

Hendrik Zschocke 111.1 19 In the first step, the __[[text variable>>doc:ONYX.Erstellung von Testinhalten.Aufgaben.Variablen verwenden.Text Variables.WebHome||shape="rect"]]__ {div} in a condition is set to the value "less" or "more" in the tab **//Variables//**, depending on whether the answer given by the learner was less than or greater than the correct answer.

Hendrik Zschocke 111.1 21 In addition, the learner's answer will be stored in a __[[numerical variable>>doc:ONYX.Erstellung von Testinhalten.Aufgaben.Variablen verwenden.Numerische Variablen.WebHome||shape="rect"]]__ {answer} so that it can be easily accessed from within the feedback.

Hendrik Zschocke 111.1 29 In the second step, concrete task feedback is stored. The participant should see the feedback only if they have submitted an incorrect answer. Therefore, the general feedback **//Answer was wrong// **needs to be selected from the tab **//Feedback//**. For more information about task feedback, refer to the help page [[__Set feedback__>>doc:ONYX.Erstellung von Testinhalten.Aufgaben.Feedback festlegen.WebHome]].

Hendrik Zschocke 111.1 31 Individual feedback and values stored in the variables can be included in the feedback by entering the variable name ({div}, {answer}).

Hendrik Zschocke 111.1 33 Additional feedback blocks can be added as individual feedback. In the example, a hint was added to the feedback, which is permanently displayed regardless of the learner's answer. Feedback can also contain detailed sample solutions and calculations. For tasks with random parameters, for example, pre-processed variables can be added to the feedback.

Hendrik Zschocke 111.1 41 Since the task contains random parameters, different values will be displayed for each test attempt and participant. According to the defined content, the participant will now additionally be shown individual feedback based on their answer.

Hendrik Zschocke 111.1 43 You can decide whether to retain the random parameters of a task or have them redefined for future attempts. For more information, see the section **//Reset variables// **on the help page [[__Set test options__>>doc:ONYX.Erstellung von Testinhalten.Test erstellen.Test-Optionen festlegen.WebHome]].
